1 2 3 Second Hospital of traditional Chinese Medicine(Rongming Lin) 4 5 6 ABSTRACT 7 8 9 Objective: To evaluated the safety and efficacy of herbal medicine for 10 11 the treatment of acute intracerebral hemorrhage (AICH) within a 6h time 12 13 14 window. 15 16 For peer review only 17 Study design: A randomized, multicenter, doubleblind, 18 19 placebocontrolled study performed in 14 hospitals in China. 20 21 22 23 Participants and Interventions: Patients with AICH were randomly 24 25 assigned to receive a placebo, the ICH1 formula (8 herbs, including the 26 27 28 removing blood stasis (RBS) herbs hirudo and tabanus) or the ICH2 29 30 formula (6 herbs without the RBS herbs hirudo and tabanus) within 6 h 31 32 of ICH onset. 33 34 35 36 Outcomes: The primary safety outcome was the hematoma enlargement 37 38 (HE)rate at 24 h and on 10 days after treatment. The secondary outcome 39 40 41 endpoint was incidence of poor prognosis (mortality or modified Rankin 42 43 Scale (mRS) score ≥5) assessed on 90 days after symptom onset. 44 45 46 Results: A total of 324 subjects were randomized between October 2013 47 48 49 and May 2016: 105 patients received placebo; 108 patients received the 50 51 ICH1 formula; and 111 patients received the ICH2 formula. The HE 52 53 54 rates at 24 h were 7.8% in the placebo group, 12.3% in the ICH1 group, 55 56 and 7.5% in the ICH2 group, and the HE rates on day 10 were 1.1% in 57 2 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 4 of 55

1 2 3 4 the placebo group, 1.1% in the ICH1 group, and 3.1% in the ICH2 5 6 group, with no significant differences between the groups (P>0.05). The 7 8 9 mortality rates were 3.8% in the placebo group, 2.8% in the ICH1 group, 10 11 and 0.9% in the ICH2 group,and the incidences of poor prognosis were 12 13 7.1% in the placebo group, 6.0% in the ICH1 group, and 4.8% in the 14 15 16 ICH2 groupFor at 3 peer months, with review no significant only differences between the 17 18 groups (P>0.05). However, the overall frequency of adverse events in the 19 20 21 ICH1 group (12.1%) was higher than that in the placebo and ICH2 22 23 groups (5.8% and 2.8%, respectively, P<0.022). The 3 cases of serious 24 25 26 adverse events were all in the ICH1 group. 27 28 29 Conclusions: Ultraearly administration of RBS herbal medicine, within 30 31 6 h of ICH onset, for AICH patients did not exert significantly beneficial 32 33 34 effects on clinical outcomes, but increased the risk of bleeding, such as 35 36 gastrointestinal bleeding, and hematoma growth. 37 38 39 Clinical Trial Registration: URL:http//www.ClinicalTrials.gov. 40 41 42 Unique identifier: NCT01918722. 43 44 45 Keywords: intracerebral hemorrhage; herbal medicine; randomized 46 47 48 controlled trials; hematoma enlargement; CRRICH 49 50 51 Word count: 4568 52 53 54 55 56 57 3 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 5 of 55 BMJ Open

1 2 3 4 Strengths and limitations of this study 5 6 7 ▪ The CRRICH trial is the largest Multicenter clinical trial to examine the 8 9 safety and efficacy of a Chinese compound formula in patients with 10 11 12 HICH. 13 14 15 ▪ This study highlights the possibility that the early use of RBS herbal 16 For peer review only 17 medicine in HICH could increase the risk of bleeding, which spurs further 18 19 20 research on the safety of Chinese medicines. 21 22 23 ▪ there were no available data to elucidate the mechanism of AEs or 24 25 26 serious AEs. 27 28 29 30 31 32 Introduction 33 34 35 Hypertensive intracerebral hemorrhage (HICH) accounts for 36 37 [1] 38 approximately 15% of all acute strokes which is the third most common 39 40 cause of death in most Western countries, following coronary heart 41 42 [2, 3] 43 disease and cancer. HICH has been the leading cause of death in 44 [4] 45 China in recent years, being responsible for approximately onethird of 46 47 [5] the total number of deaths from stroke worldwide. 48 49 50 51 Available specific medical and surgical treatments do not improve 52 53 prognosis substantially,[7, 8] and intracerebral hemorrhage (ICH) still 54 55 56 accounts for a higher proportion of stroke in Chinese people compared 57 4 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 6 of 55

1 2 3 [6] 4 with that in white populations. Therefore, traditional Chinese medicine 5 6 (TCM) physicians in China widely use removing blood stasis (RBS) 7 8 9 herbs for the treatment of HICH, which was proven previously to provide 10 [9] 11 some benefit for HICH patients in a metaanalysis. RBS herbal 12 13 medicine maybe promotes hematoma absorption and improves recovery 14 15 [10, 11] 16 of neurologicalFor impairment peer review, which is already only included by a 17 18 guidelines for the management of spontaneous intracerebral 19 20 [24] 21 hemorrhage .However, sufficient evidence of longterm benefits and 22 23 risks of superacute stage is lacking. RBS herbals, such as hirudo, that act 24 25 26 as a thrombin inhibitor with anticoagulant pharmacological effects, may 27 28 cause rebleeding risk in clinical practice.[12] A total of 90% of hematoma 29 30 31 growth, which plays an important role in prognosis, occurs within a 6h 32 [13] 33 time window. Therefore, confirmation of the safety and efficacy of 34 35 RBS herbal medicines in the treatment of earlystage HICH is urgently 36 37 38 needed. 39 40 41 We performed a retrospective study that demonstrated that RBS 42 43 [14] 44 herbal medicine for HICH patients was safe and effective. However, 45 46 little additional evidence of the safety and efficacy of this treatment exists. 47 48 We designed a multicenter, threegroup, prospective, randomized, 49 50 51 doubleblinded and placebocontrolled clinical trial on hematoma 52 53 enlargement in HICH patients treated with RBS herbal medicine within a 54 55 56 6h time window from symptom onset (CRRICH) to evaluate its safety 57 5 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 7 of 55 BMJ Open

This trial is registered at 22 23 clinicaltrials.gov (NCT01918722), and the research design proposal has 24 25 [15] 26 been published. 27 28 29 Participants 30 31 32 Patients with a Glasgow Coma Scale [GCS] score ≥6 were enrolled 33 34 if they were ≥18 years of age and had a clinical diagnosis of ICH 35 36 37 confirmed with computed tomography within 6h of onset. All participants 38 39 signed an informed consent form. Patients who suffered secondary ICH 40 41 42 resulting from trauma, brain tumor, blood diseases, arteriovenous 43 44 malformation or aneurysm were excluded. A detailed patient history was 45 46 47 recorded.

The 30 31 32 study consisted of a screening and randomization period (≤6 h 33 34 poststroke), a 10day doubleblinded treatment period and a 3month 35 36 37 followup period (S1 Figure in the onlineonly Data Supplement). 38 39 Participants were randomly assigned to one of three treatment groups at a 40 41 42 ratio of 1:1:1 during the doubleblinded treatment: (1) Group ICH1 43 44 received the ICH1 formula, which consisted of 8 herbs including RBS 45 46 medicines [Hirudo, Tabanus, Rhubarb, Typha angustifolia L, Fructus 47 48 49 trichosanthis, Panax notoginseng, Acorus tatarinowii, and Chinemys 50 51 reevesii (Gray)]; (2) Group ICH2 received the ICH2 formula, which 52 53 54 consisted of 6 herbal medicines without RBS herbs [Rhubarb, Typha 55 56 angustifolia L, Fructus trichosanthis, Panax notoginseng, Acorus 57 7 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 9 of 55 BMJ Open

1 2 3 4 tatarinowii, and Chinemys reevesii (Gray)] in the same doses as ICH1, 5 6 with the remaining dose filled with a placebo; and (3) Group placebo 7 8 9 received a placebo that included dextrin and farina. Each unit of TCM 10 11 medicine or placebo was dissolved in 200 ml of boiling water. Each 12 13 patient received 200 ml orally or through a nasogastric tube two times 14 15 16 daily for 10For days (S2 peer Table in thereview onlineonly Data only Supplement). 17 18 19 Patients were followed up for 3 months after the 10day 20 21 22 doubleblinded treatment period. Patients were hospitalized in stroke 23 24 units and received standard stroke care in accordance with local 25 26 guidelines, which included general supportive care, treatment of acute 27 28 29 complications, and rehabilitation. Astringents and other RBS drugs were 30 31 prohibited. Visits were scheduled at baseline, 24 h poststroke, at the end 32 33 34 of the treatment period, and a single visit was scheduled 3 months 35 36 poststroke (S1 Figure in the onlineonly Data Supplement). Adverse 37 38 39 events (AEs), treatment compliance, and concomitant medication use 40 41 were reported during each visit. Participants were randomly assigned to 42 43 44 one of three treatment groups at a ratio of 1:1:1 during doubleblinded 45 46 treatment. 47 48 49 Primary and Secondary Outcomes 50 51 52 The hematoma enlargement rate, which is a radiographic outcome, 53 54 55 was the primary outcome in the study. Hematoma enlargement was 56 57 8 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 10 of 55

1 2 3 4 operationally defined as an increase in hematoma volume of >33% or 5 6 12.5 ml as measured on image analysis on the 24h CT compared with the 7 8 9 baseline CT scan. Hematoma volume was measured using the ABC/2 10 [16] 11 Coniglobus formula at 24 h after onset. The same measurement was 12 13 performed on days 1014 as a primary outcome measure. The following 14 15 16 secondary Forend points peer were assessed: review change in NIHSS only score at 3 months; 17 18 mortality at 3 months; and poor prognosis rate, which was defined as the 19 20 21 proportion of patients who died or were severely disabled based on an 22 23 mRS score ≥5 at 3 months.[17] Safety data focused on treatmentemergent 24 25 26 AEs (TEAEs). TEAEs were defined as AEs that first occurred or 27 28 worsened (increased in severity) after the first dose of study drug. The 29 30 31 patient spontaneously reported TEAEs in response to an openended 32 33 question from the contact person at each visit. Patients with a worsened 34 35 condition, prolonged hospitalization, and lifethreatening TEAEs were 36 37 38 reported as serious adverse events (TEsAEs). Abnormal laboratory values 39 40 that constituted a serious AE or led to the discontinuation of experimental 41 42 43 drugs were also reported as TEsAEs.

1 2 3 4 analysis set (FAS) (patients who were randomized and received any study 5 6 medication) according to the intenttotreat (ITT) principle. Supportive 7 8 9 analyses were performed in a predefined per protocol population set 10 11 (PPS), which included FAS patients who did not have one or more key 12 13 protocol deviations, including violations of inclusion and exclusion 14 15 16 criteria. TheFor last observation peer for review surviving patients only with missing outcome 17 18 data was carried forward. Patients who had died at the 90day followup 19 20 21 were assigned a Barthel index score of 0 and mRS score of 6, and the last 22 23 recorded NIHSS score was carried forward. Hematoma enlargement rate 24 25 26 at 24 h (primary end point), the rate of poor prognosis and the incidence 27 28 of total adverse events between the three groups were analyzed using the 29 30 2 31 χ test. The hematoma enlargement rate on days 1014 (primary end point) 32 33 and mortality between the three groups were compared using Fisher’s 34 35 exact test. Mean differences in NIHSS score between groups were 36 37 38 analyzed using oneway ANOVA. Demographic characteristics and 39 40 serious AEs were summarized using descriptive statistics. 41 42 43 44 Power and sample size were determined using relative hematoma 45 46 volume at 24 h as the primary outcome variable. A total of 285 47 48 participants were required at the final followup to provide 90% power 49 50 51 with a twosided alpha level at 0.05 to test the primary effectiveness, 52 53 which was calculated using the PASS (Power Analysis and Sample Size) 54 55 56 software program (licensed by NCSS, LLC).

Dr. Jianwen Guo had full access to all study data 5 6 and had final responsibility for the decision to submit for publication. 7 8 9 Each respective institutional review board or ethics committee 10 11 12 approved the study protocol, which followed established Good Clinical 13 14 Practice guidelines. All patients provided written informed consent to 15 16 For peer review only 17 participate in the study. An independent contract research organization, 18 19 S&R (Department of Science and Research of Guangdong Provincial 20 21 22 Hospital of Chinese medicine), managed the administration, coordination, 23 24 and monitoring of the study, including researcher training, study 25 26 inspection, data management and statistical analyses, with oversight by 27 28 29 the State Administration of Traditional Chinese Medicine of the P.R.C. 30 31 32 Results 33 34 35 Study Population 36 37 Patient recruitment began in October 2013, and the study ended in 38 39 40 May 2016. A total of 5589 individuals with ICH were screened (Figure 1). 41 42 The most frequent reasons for exclusion in descending order were time 43 44 45 window >6 hours, refusal to participate, secondary ICH (i.e., not HICH) 46 47 and other reasons. A total of 319 of the 324 randomized patients (105 48 49 50 placebo, 108 ICH1, 111 ICH2) received the assigned treatment 51 52 following the elimination of five patients (one patient for missing the 53 54 55 time window, one patient for kidney failure, one patient for secondary 56 57 12 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 14 of 55

1 2 3 4 ICH, one patient for surgery within 24 h and one patient withdrew 5 6 consent). Therefore, only the 319 participants who underwent 7 8 9 randomization and received study medication were included in the FAS 10 11 and safety analysis set based on ITT. Twentythree patients in the FAS 12 13 did not completely adhere to the protocol and dropped out during the 14 15 16 treatment period.For A peertotal of 296 review patients were included only in the PPS (see 17 18 Figure 1 for patient flow diagram). The mean dropout rate was <8%. 19 20 21 Table 1 presents the demographics and baseline characteristics of the 22 23 FAS, which were well balanced with no significant betweengroup 24 25 26 differences. The mean age was 62.5±12.7 years (mean±SD, n=319); 27 28 65.5% of the patients were male, and 98.7% were ethnic Han. The 29 30 31 median GCS score was 15 (range, 3 to 15), and the mean NIHSS score 32 33 was 8 (range, 0 to 47). The deep gray matter was involved in 93.4% of 34 35 cases, and the lobar regions were involved in 6.6% of cases. The baseline 36 37 38 characteristics of the three treatment groups were similar. The mean 39 40 volume of the ICH at baseline for all patients was 11.0 ml (range, 0.3 to 41 42 43 86.7 ml), which was similar in the three groups (Table 1). The mean time 44 45 from onset of symptoms to admission was 3.36±1.49 h, and the mean 46 47 48 time from onset of symptoms to treatment was 4.10±1.38 h. Fourteen 49 50 percent of patients were treated within 3 h after symptom onset. Two 51 52 53 patients were treated outside the 6h time window. The timing of the 54 55 treatment was similar in the three groups (Table 1). 56 57 13 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 15 of 55 BMJ Open

1 2 3 4 RBS administration within 6 h after symptom onset of ICH did not 5 6 significantly reduce hematoma growth and failed to improve survival or 7 8 9 functional outcome at 90 days. Conversely, the incidence of AEs 10 11 increased significantly. A significant increase was demonstrated in total 12 13 AE frequency and serious AEs. Three serious bleeding events occurred in 14 15 16 the RBS groupFor (ICH1, peer with 2 RBSreview herbals), including only two cases of 17 18 gastrointestinal bleeding and one case of intracerebral rebleeding. All 19 20 21 three cases were fatal serious AEs (Table 2). These data suggest that RBS 22 23 treatment for ICH patients within 6 h of symptom onset is a safety 24 25 26 concern. However, no data were available to suggest a mechanism for 27 28 this effect. 29 30 31 This result contrasts with the clinical benefit demonstrated in a 32 33 [9] 34 previous metaanalysis , which included 9 randomizedcontrolled 35 36 clinical trials with 798 individuals who demonstrated that RBS therapy 37 38 39 for acute ICH reduced brain hematoma and cerebral edema volumes, 40 41 improved the neural function and reduced the mortality and disability 42 43 44 rates with fewer AEs. The present trial revealed significant heterogeneity 45 46 compared with the studies included in the metaanalysis possibly because 47 48 of differences in the intervention time window. This research is the first 49 50 51 prospective, multicenter, randomized, doubleblind, placebocontrolled 52 53 study to assess the effect and safety of RBS in HICH patients within a 6h 54 55 56 time window from symptom onset, unlike prior studies that examined 57 19 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 21 of 55 BMJ Open

1 2 3 4 these effects within a 24h or later intervention time window. Earlier RBS 5 6 administration increased the risk of bleeding events (e.g., gastrointestinal 7 8 9 bleeding or intracerebral rebleeding) counteracted the benefit to some 10 11 extent. 12 13 14 The primary outcome of the rate of hematoma enlargement, which is 15 16 For peer review only [17] 17 an independent prognostic determinant of mortality and poor prognosis, 18 19 was also used to assess safety. The hematoma enlargement rates at 24 h in 20 21 22 the three groups in the CRRICH trial (placebo, ICH2, and ICH1) were 23 24 7.8%, 7.5%, and 12.3%, respectively, which were not significantly 25 26 different (Table 2). The mean hematoma enlargement rate was only 9.2%, 27 28 [27] 29 which was far lower than the mean level of 1830%. The main reasons 30 31 of lower hematoma expansion incidence may include the following: (1) 32 33 34 the investigators’ inclination toward surgery in HICH patients with large 35 36 hemorrhage volumes within 24 h of onset, which resulted in the exclusion 37 38 39 of patients susceptible to rebleed in the study; and (2) patients with 40 41 terrible and unstable conditions who were prone to hematoma expansion 42 43 44 were excluded by investigators privately for fear that deterioration risk 45 46 would rise during study. 47 48 49 Hematoma growth is an independent determinant of death and 50 51 [18] 52 disability. Therefore, hematoma expansion may be an attractive 53 54 therapeutic target.[19, 20] However, no proven specific therapies or 55 56 57 20 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 22 of 55

1 2 3 4 treatments exist to prevent hematoma expansion or improve outcomes 5 6 after ICH. Sufficient evidencebased medical research to prove that 7 8 9 minitraumatic surgeries and the present available medicines provide 10 [7, 8] 11 ideal treatment is lacking. 12 13 14 Herbal medicine in China has been used to treat ICH for at least 2,000 15 16 For peer review only 17 years, and RBS herbal medicines are listed in the 2010 Chinese 18 [21] 19 Pharmacopeia. Dr. Si reported the earliest available literature on HICH 20 21 [22] 22 with RBS herbal medicine therapy in 1981. Another RBS medicine, 23 24 Naoxuekang capsule, was approved as routine treatment for HICH 25 [21] 26 patients by the Chinese state food and drug administration . 27 28 29 (Naoxuekang capsule, register No. Z10960009). RBS herbal medicines 30 31 have been studied in HICH patients in more than 200 clinical studies in 32 33 34 the past 30 years, and it gradually became a regular therapy that reached a 35 36 consensus.[23] HICH management guideline in China cited this 37 38 [24] 39 treatment. However, safety evidence in the early stage of HICH is 40 41 lacking. Some studies demonstrated 30% of ICH patients suffered 42 43 [25] 44 continued bleeding within 6 h of onset . Some research has provided 45 46 lowlevel evidence of the safety of RBS herbal medicine for superacute 47 48 cerebral hemorrhage, but whether RBS herbal medicine administration in 49 50 51 an earlystage induced hematoma growth was not known because RBS 52 53 herbal medicine exhibits an anticoagulation effect.[26] Marketed RBS 54 55 56 drugs that are clinically recognized and widely used did not illustrate a 57 21 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 23 of 55 BMJ Open

1 2 3 4 specific application time window. Early administration of RBS drugs may 5 6 cause hematoma expansion and increase the risk of death and serious 7 8 9 disability. The CRRICH trial was a prospective, doubleblinded, 10 11 multicenter clinical trial that demonstrated that early administration of 12 13 RBS drugs did not increase hematoma growth but significantly increased 14 15 16 AEs. For peer review only 17 18 19 The CRRICH trial is the largest clinical trial to investigate the safety 20 21 22 and efficacy of a Chinese compound formula in patients with HICH. 23 24 Three other influential RCT trials of medical treatment with drugs that 25 26 exhibit very different mechanisms than RBS, including FAST, 27 28 29 INTERACT2, and CHANT, used similar methods to evaluate the safety 30 31 and efficacy and found no significant benefit.[2830] 32 33 34 35 Data from the clinical study suggested that administration of RBS 36 37 herbal medicine should be avoided in HICH patients during the initial 6h 38 39 time window from stroke onset to avoid the increased risk of bleeding. 40 41 42 Further clinical studies should be performed to confirm the safety and 43 44 efficacy of these agents beyond the 6 h of ICH onset. This research 45 46 47 suggests that early administration of RBS herbal medicine in ICH patients 48 49 increases the risk of bleeding, such as gastrointestinal bleeding and 50 51 52 hematoma growth. Some Chinese patent drugs (Naoxuekang capsule 53 54 (Z10960009), Naoxuekang pill (Z20050312) or Naoxuekang drop pills 55 56 57 22 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 24 of 55

1 2 3 4 (Z10980039)), which primarily consist of hirudo, should be reevaluated 5 6 and used under supervision. The relevant manufacturers should revise the 7 8 9 drug instruction and add a warning of “Do not use for superacute cerebral 10 11 hemorrhage within 6 h from onset”, if necessary. 12 13 14 This study had some limitations. First, there were no available data 15 16 For peer review only 17 to elucidate the mechanism of AEs or serious AEs. Second, there was a 18 19 significant difference in the number of patients between research centers. 20 21 22 Third, the investigators would rather study on the patients with minor 23 24 hematoma’ volume, because they were afraid of the rebleeding risk of the 25 26 herbal medicine. 27 28 29 30 Summary 31 32 33 This study demonstrates that ultraearly administration of RBS 34 35 herbal medicine, within 6 h of ICH onset, for AICH patients increased the 36 37 38 risk of bleeding, such as gastrointestinal bleeding, and hematoma growth. 39 40 It also shows that RBS herbal medicine did not exert significantly 41 42 43 beneficial effects on clinical outcomes in hypertensive ICH patients in the 44 45 ultraearly stage. These results support that ultraearly administration of 46 47 48 RBS herbal medicine is unsafe and less effective. Future highquality 49 50 research should further assess the effectiveness and safety of herbal 51 52 medicine for the intracerebral hemorrhage beyond 6 hrs time window. 53 54 55 56 57 23 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 25 of 55 BMJ Open

The secondary 49 50 51 outcome was the incidence of poor prognosis (mortality or modified 52 53 54 Rankin Scale (mRS) score ≥5) assessed at 90 days after symptom onset. 55 56 57 Results: A total of 324 subjects were randomized between October 2013 58 59 60 and May 2016: 105 patients received placebo; 108 patients received the 2

1 2 3 4 ICH-1 formula; and 111 patients received the ICH-2 formula. The 5 6 7 incidence of hematoma enlargement at 24 h were 7.8% in the placebo 8 9 group, 12.3% in the ICH-1 group, and 7.5% in the ICH-2 group; the 10 11 12 incidence of hematoma enlargement on day 10 were 1.1% in the placebo 13 14 15 group, 1.1% in the ICH-1 group, and 3.1% in the ICH-2 group, with no 16 17 significant differences among the groups (P>0.05). The mortality rates 18 For peer review only 19 20 were 3.8% in the placebo group, 2.8% in the ICH-1 group, and 0.9% in 21 22 the ICH-2 group; the incidences of poor prognosis were 7.1% in the 23 24 25 placebo group, 6.0% in the ICH-1 group, and 4.8% in the ICH-2 group at 26 27 28 3 months, with no significant differences among the groups (P>0.05). 29 30 However, the overall frequency of treatment-emergent adverse events in 31 32 33 the ICH-1 group (12.1%) was higher among the three groups (5.8% and 34 35 2.8%, respectively, P<0.05). All 3 cases of serious adverse events were 36 37 38 in the ICH-1 group. 39 40 41 Conclusions: Ultra-early administration, namely, within 6 h of ICH 42 43 44 onset, of RBS herbal medicine for AICH patients did not exert significant 45 46 47 beneficial effects on clinical outcomes but increased the risk of bleeding, 48 49 such as gastrointestinal bleeding, and hematoma growth. 50 51 52 53 Clinical Trial Registration: URL:http//www.ClinicalTrials.gov. 54 55 Unique identifier: NCT01918722. 56 57 58 59 Keywords: intracerebral hemorrhage; herbal medicine; randomized 60 3

1 2 3 4 controlled trials; hematoma enlargement; CRRICH 5 6 7 8 Word count: 4646 9 10 11 Strengths and limitations of this study 12 13 14 ▪ The CRRICH trial is the largest multicenter clinical trial to examine the 15 16 17 safety and efficacy of a Chinese compound formula in patients with 18 For peer review only 19 20 AICH. 21 22 23 ▪ This study highlights the possibility that the early use of RBS herbal 24 25 26 medicine in AICH could increase the risk of bleeding, which spurs further 27 28 research on the safety of Chinese medicines. 29 30 31 32 ▪ There were no available data to elucidate the mechanisms of TEAEs or 33 34 serious TEAEs. 35 36 37 38 39 40 41 Introduction 42 43 44 [1] 45 Acute intracerebral hemorrhage accounts for approximately 15% of 46 47 all acute strokes; stroke is the third most common cause of death in most 48 49 [2, 3] 50 Western countries, following coronary heart disease and cancer. 51 52 AICH has been the leading cause of death in China in recent years[4] and 53 54 55 is responsible for approximately one-third of the total number of deaths 56 57 [5] 58 from stroke worldwide. 59 60 4

1 2 3 4 Available specific medical and surgical treatments do not improve 5 6 [6, 7] 7 prognosis substantially, and AICH still accounts for a higher 8 9 proportion of stroke in Chinese people than in white populations.[8] 10 11 12 Therefore, traditional Chinese medicine (TCM) physicians in China 13 14 15 widely use removing blood stasis (RBS) herbs for the treatment of AICH. 16 17 Meta-analysis showed that RBS herbal therapy for AICH could improve 18 For peer review only 19 20 the neurological function deficit, reduce the volume of hematoma and 21 22 perihematomal edema, and lower the mortality rate and dependency.[9] It 23 24 25 is possible that RBS herbal medicine promotes hematoma absorption and 26 27 [10, 11] 28 improves the recovery of neurological impairment ; RBS herbal 29 30 medicine has already been included by guidelines for the management of 31 32 33 spontaneous ICH. However, sufficient evidence of long-term benefits and 34 35 risks of superacute stage is lacking. RBS herbals, such as Hirudo 36 37 38 nipponica Whitman, which acts as a thrombin inhibitor with anticoagulant 39 40 [12] 41 pharmacological effects, may cause rebleeding risk in clinical practice. 42 43 A total of 90% of hematoma growth, which plays an important role in 44 45 [13] 46 prognosis, occurs within a 6-h time window. Therefore, a confirmation 47 48 of the safety and efficacy of RBS herbal medicines in the treatment of 49 50 51 early-stage AICH is urgently needed. 52 53 54 We performed a retrospective study that demonstrated that RBS 55 56 57 herbal medicine for AICH patients was safe and effective.[14] However, 58 59 60 little additional evidence of the safety and efficacy of this treatment 5

1 2 3 4 exists. We designed a multicenter, three-group, prospective, randomized, 5 6 7 double-blinded and placebo-controlled clinical trial on hematoma 8 9 enlargement in AICH patients treated with RBS herbal medicine within a 10 11 12 6-h time window from symptom onset (CRRICH) to evaluate its safety 13 14 15 and efficacy in AICH patients and to provide a high level of evidence for 16 17 clinical practice. 18 For peer review only 19 20 21 Methods 22 23 24 Study Design 25 26 27 The CRRICH trial was a multicenter, randomized, double-blinded, 28 29 30 placebo-controlled, parallel-group study to assess the safety and efficacy 31 32 33 of RBS herbal medicine in AICH patients. This trial is registered at 34 35 clinicaltrials.gov (NCT01918722), and the research design proposal has 36 37 [15] 38 been published. 39 40 41 Participants 42 43 44 45 Patients with a Glasgow Coma Scale [GCS] score ≥6 were enrolled 46 47 if they were ≥18 years of age and had a clinical diagnosis of ICH 48 49 50 confirmed with computed tomography within 6 h of onset. All 51 52 participants signed an informed consent form. If the participants don’t 53 54 55 have the capacity to sign the informed consent for serious condition or 56 57 58 illiteracy, the researcher will explain the informed consent to the patients 59 60 or their authorized immediate family.

1 2 3 4 sides, their immediate family will decide whether to sign the informed 5 6 7 consent on behalf of the patient. Patients who suffered secondary ICH 8 9 resulting from trauma, brain tumor, blood diseases, arteriovenous 10 11 12 malformation or aneurysm were excluded. A detailed patient history was 13 14 15 recorded. S1 Table in the online-only Data Supplement provides a full list 16 17 of study inclusion and exclusion criteria during the screening period. 18 For peer review only 19 20 21 Randomization and Blinding 22 23 24 Patients were randomized to receive placebo, ICH-1, or ICH-2 in 25 26 27 a 1:1:1 ratio with a stratification and block size of 6 using the PROC 28 29 PLAN process in SAS software version 9.13. Stratified block and 30 31 32 randomization were concealed using sequentially numbered opaque 33 34 envelopes. Persons involved in the study, including the investigators, 35 36 37 patients and data analysts, were blinded to treatment assignment during 38 39 40 double-blinded treatment until the end of follow-up. Only the data 41 42 administrators were permitted access to unblinded data. 43 44 45 46 Procedures 47 48 Enrollment, Intervention and Follow-up 49 50 51 Patients were recruited from October 2013 through May 2016 at 14 52 53 54 hospitals in China (S2 Table in the online-only Data Supplement). The 55 56 57 study consisted of a screening and randomization period (≤6 h poststroke), 58 59 a 10-day double-blinded treatment period and a 3-month follow-up period 60 7

1 2 3 4 (S1 Figure in the online-only Data Supplement). Participants were 5 6 7 randomly assigned to one of three treatment groups at a ratio of 1:1:1 8 9 during the double-blinded treatment (shown in the S3 and S4 Table in the 10 11 12 online-only Data Supplement): (1) The ICH-1 group received the ICH-1 13 14 15 formula, which consisted of 8 herbs including RBS medicines; (2) The 16 17 ICH-2 group received the ICH-2 formula, which consisted of 6 herbal 18 For peer review only 19 20 medicines without RBS herbs(Hirudo nipponica Whitman and Tabanus 21 22 bivittatus Matsumura) in the same doses as those in the ICH-1 group, 23 24 25 with the remaining dose filled with a placebo; and (3) The placebo group 26 27 28 received a placebo that included dextrin and farina. Each unit of TCM 29 30 medicine or placebo was dissolved in 200 ml of boiling water. Each 31 32 33 patient received 200 ml orally or through a nasogastric tube two times 34 35 daily for 10 days (S3 Table in the online-only Data Supplement). 36 37 38 39 Patients were followed up for 3 months after the 10-day 40 41 double-blinded treatment period. Patients were hospitalized in stroke 42 43 44 units and received standard stroke care in accordance with local 45 46 47 guidelines, which included general supportive care, treatment of acute 48 49 complications, and rehabilitation. Astringents and other RBS drugs were 50 51 52 prohibited. Visits were scheduled at baseline, 24 h poststroke, and at the 53 54 end of the treatment period, with a single visit scheduled 3 months 55 56 57 poststroke (S1 Figure in the online-only Data Supplement). Adverse 58 59 60 events (AEs), treatment compliance, and concomitant medication use 8

1 2 3 4 were reported during each visit. Participants were randomly assigned to 5 6 7 one of three treatment groups at a ratio of 1:1:1 during double-blinded 8 9 treatment. 10 11 12 13 Primary and Secondary Outcomes 14 15 16 The incidence of hematoma enlargement, which was defined as the 17 18 For peer review only 19 percentage of participants experienced hematoma enlargement, was the 20 21 primary outcome of the study. Hematoma enlargement was operationally 22 23 24 defined as an increase in hematoma volume of >33% or 12.5 ml, as 25 26 27 measured on image analysis on the 24-h CT compared with the baseline 28 29 CT scan. Hematoma volume was measured using the ABC/2 Coniglobus 30 31 [16] 32 formula at 24 h after onset. The same measurement was performed on 33 34 days 10-14 as a primary outcome measure. The following secondary end 35 36 37 points were assessed: change in NIHSS score at 3 months; mortality at 3 38 39 40 months; and poor prognosis rate, which was defined as the proportion of 41 42 patients who died or were severely disabled based on an mRS score ≥5 at 43 44 [17] 45 3 months. Safety data focused on treatment-emergent AEs (TEAEs). 46 47 TEAEs were defined as AEs that first occurred or worsened (increased in 48 49 50 severity) after the first dose of study drug. The patient spontaneously 51 52 53 reported TEAEs in response to an open-ended question from the contact 54 55 person at each visit. A worsened patient condition, prolonged patient 56 57 58 hospitalization, and life-threatening TEAEs in patients were reported as 59 60 9

1 2 3 4 serious adverse events (TEsAEs). Abnormal laboratory values that 5 6 7 constituted a serious AE or led to the discontinuation of experimental 8 9 drugs were also reported as TEsAEs. S5 Table in the online-only Data 10 11 12 Supplement provides a full list of all primary, secondary and safety end 13 14 15 points. 16 17 18 Statistical AnalysesFor peer review only 19 20 21 All reported efficacy analyses were predefined and based on the full 22 23 24 analysis set (FAS) (patients who were randomized and received any study 25 26 27 medication) according to the intent-to-treat (ITT) principle. Supportive 28 29 analyses were performed in a predefined per-protocol population set 30 31 32 (PPS), which included FAS patients who did not have one or more key 33 34 protocol deviations, including violations of inclusion and exclusion 35 36 37 criteria. The last observation for surviving patients with missing outcome 38 39 40 data was carried forward. Patients who had died by the 90-day follow-up 41 42 were assigned a Barthel index score of 0 and an mRS score of 6, and the 43 44 45 last recorded NIHSS score was carried forward. The incidence of 46 47 hematoma enlargement at 24 h (primary end point), the rate of poor 48 49 50 prognosis and the incidence of total TEAEs among the three groups were 51 52 2 53 analyzed using the χ test. The incidence of hematoma enlargement on 54 55 days 10-14 (primary end point) and mortality among the three groups 56 57 58 were compared using Fisher’s exact test. The mean differences in NIHSS 59 60 10

1 2 3 4 score among groups were analyzed using one-way ANOVA. 5 6 7 Demographic characteristics and serious TEAEs were summarized using 8 9 descriptive statistics. 10 11 12 13 Power and sample size were determined using relative hematoma 14 15 volume at 24 h as the primary outcome variable. A total of 285 16 17 18 participants wereFor required peer at the review final follow-up only to provide 90% power 19 20 21 with a two-sided alpha level at 0.05 to test the primary efficacy, which 22 23 was calculated using the PASS (Power Analysis and Sample Size) 24 25 26 software program (licensed by NCSS, LLC). A total of 360 participants 27 28 were needed for primary outcome randomization assuming a dropout rate 29 30 31 of 20%, with 120 patients per treatment arm. The statistical package 32 33 34 STATA (version 13.1) was used for all statistical analyses. 35 36 37 Patient and Public Involvement Statement 38 39 40 While we put forward the research question and outcome measures, 41 42 43 the patients’ priorities, experience, and preferences were fully considered 44 45 46 by a survey. Patients were involved in the recruitment to and conduct of 47 48 the study. The results would be disseminated to study participants by 49 50 51 posting a letter. The CRRICH trial was a randomized controlled trial, and 52 53 the patients themselves had fully assessed the burden of the intervention. 54 55 56 Patient advisors should also be thanked in the contributorship 57 58 59 statement/acknowledgments. 60 11

A total of 5589 individuals with ICH were screened (Figure 1). 17 18 For peer review only 19 The most frequent reasons for exclusion in descending order were time 20 21 window >6 h, refusal to participate, secondary ICH (i.e., not AICH) and 22 23 24 other reasons. A total of 319 of the 324 randomized patients (105 placebo, 25 26 108 ICH-1, 111 ICH-2) received the assigned treatment following the 27 28 29 elimination of five patients (one patient for missing the time window, one 30 31 32 patient for kidney failure, one patient for secondary ICH, one patient for 33 34 surgery within 24 h and one patient withdrew consent). Therefore, only 35 36 37 the 319 participants who underwent randomization and received study 38 39 medication were included in the FAS and safety analysis set based on ITT. 40 41 42 Twenty-three patients in the FAS did not completely adhere to the 43 44 45 protocol and dropped out during the treatment period. A total of 296 46 47 patients were included in the PPS (see Figure 1 for patient flow diagram). 48 49 50 The mean dropout rate was <8%. Table 1 presents the demographics and 51 52 baseline characteristics of the FAS, which were well balanced with no 53 54 55 significant between-group differences. The mean age was 62.5±12.7 56 57 58 years (mean±SD, n=319); 65.5% of the patients were male, and 98.7% 59 60 were ethnic Han. The median GCS score was 15 (range, 3 to 15), and the 13

The baseline characteristics of the three treatment groups were 10 11 12 similar. The mean volume of the ICH at baseline for all patients was 11.0 13 14 15 ml (range, 0.3 to 86.7 ml), which was similar in the three groups (Table 16 17 1). The mean time from onset of symptoms to admission was 3.36±1.49 h, 18 For peer review only 19 20 and the mean time from onset of symptoms to treatment was 4.10±1.38 h. 21 22 Fourteen percent of patients were treated within 3 h after symptom onset. 23 24 25 Two patients were treated outside of the 6-h time window. The timing of 26 27 28 the treatment was similar in the three groups (Table 1). 29 30 31 32 33 34 Figure 1. Enrollment and Follow-up.

The incidence of hematoma enlargement were 23 24 25 7.8% in the placebo group, 12.3% in the ICH-1 group and 7.5% in the 26 27 28 ICH-2 group. There was no significant difference in the incidence of 29 30 hematoma enlargement at 24 h among the three groups (P=0.409). The 31 32 33 incidence of hematoma enlargement on days 10-14 were 1.1% in the 34 35 placebo group, 3.1% in the ICH-2 group and 1.1% in the ICH-1 group. 36 37 38 There was also no significant difference among the three groups in the 39 40 41 incidence of hematoma enlargement on days 10-14 (P=0.625) (Table 2). 42 43 44 Secondary Outcomes (Clinical Outcomes) 45 46 47 48 Mortality at 3 months was approximately 2.6% in the three groups 49 50 (Table 2). Poor prognosis (i.e., the proportion of patients who died or 51 52 53 were severely disabled, mRS ≥5) did not differ significantly among the 54 55 three groups.

The modified Rankin Scale 19 20 evaluates global disability and handicap. Scores range from 0 (no symptoms or disability) to 6 (death). There were 21 no significant differences among the three groups. 22 23 24 25 26 Adverse Events 27 28 29 30 There were altogether 35 AEs reported by investigators, of which 22 31 32 AEs may have been TEAEs. All the TEAEs occurred during the 33 34 35 double-blinded treatment period (within 2 weeks). TEAEs occurred in 13 36 37 38 (12.1%) ICH-1-treated patients, 3 (2.8%) ICH-2-treated patients and 6 39 40 (5.8%) placebo-treated patients. The patterns of TEAEs were similar in 41 42 43 the 3 groups, but the overall frequencies of TEAEs among the three 44 45 groups were significantly different (P=0.022), as shown in Table 2. And 46 47 48 the paired comparisons showed that the test for difference in the overall 49 50 51 TEAEs rate between group ICH-1 and group ICH-2 yields a p-value of 52 53 0.029. Table 3 shows the TEAEs that occurred during the study. The most 54 55 56 frequent event was diarrhea, and its incidence was similar in the 3 57 58 treatment groups .

There was no consistent 10 11 12 pattern to this difference, and all serious TEAEs occurred within the 13 14 15 10-day drug treatment period. There were no statistically significant 16 17 differences in the incidence or type of serious TEAEs leading to death 18 For peer review only 19 20 among groups (data not shown).

Conversely, compared to the ICH-2, the 58 59 incidence of TEAEs showed an increasing trend in the ICH-1 group (P= 60 19

1 2 3 4 0.029, ICH-1vs. ICH-2). Significant increases were also demonstrated in 5 6 7 total TEAE frequency and in serious TEAEs in the ICH-1 group. Three 8 9 serious bleeding events occurred in the RBS group (ICH-1, with 2 RBS 10 11 12 herbals), including two cases of gastrointestinal bleeding and one case of 13 14 15 intracerebral rebleeding. All three cases were fatal serious TEAEs (Table 16 17 2). These data suggest that RBS treatment for ICH patients within 6 h of 18 For peer review only 19 20 symptom onset is a safety concern. However, no data were available to 21 22 suggest a mechanism for this effect. 23 24 25 26 As can be seen from the table 2, ICH-2 treatment 27 28 was least vulnerable to poor prognosis and TEAEs. Therefore, ICH-2 29 30 31 formula would have the potential to be an effective herbal drug for ICH 32 33 34 patients of superacute stage. 35 36 37 This result contrasts with the clinical benefit demonstrated in a 38 39 [9] 40 previous meta-analysis , which included 9 randomized controlled 41 42 clinical trials with 798 individuals, demonstrating that RBS therapy for 43 44 45 acute ICH reduced brain hematoma and cerebral edema volumes, 46 47 improved the neural function and reduced the mortality and disability 48 49 50 rates with fewer TEAEs. The present trial revealed significant 51 52 53 heterogeneity compared with the studies included in the meta-analysis, 54 55 possibly because of differences in the intervention time window. This 56 57 58 research is the first prospective, multicenter, randomized, double-blind, 59 60 20

1 2 3 4 placebo-controlled study to assess the efficacy and safety of RBS in 5 6 7 AICH patients within a 6-h time window from symptom onset, unlike 8 9 prior studies that examined these effects within a 24-h or later 10 11 12 intervention time window. Earlier RBS administration increased the risk 13 14 15 of bleeding events (e.g., gastrointestinal bleeding or intracerebral 16 17 rebleeding), which counteracted the benefit to some extent. 18 For peer review only 19 20 21 The primary outcome of the incidence of hematoma enlargement, 22 23 which is an independent prognostic determinant of mortality and poor 24 25 [18] 26 prognosis, was also used to assess safety. The incidence of hematoma 27 28 enlargement at 24 h in the three groups in the CRRICH trial (placebo, 29 30 31 ICH-2, and ICH-1) were 7.8%, 7.5%, and 12.3%, respectively, and they 32 33 34 were not significantly different (Table 2). The mean incidence of 35 36 hematoma enlargement was only 9.2%, which was far lower than the 37 38 [18] 39 mean level of 18-30%. The main reasons for lower hematoma 40 41 expansion incidence may include the following: (1) the investigators’ 42 43 44 inclination toward surgery in AICH patients with large hemorrhage 45 46 47 volumes within 24 h of onset, which resulted in the exclusion of patients 48 49 susceptible to rebleed in the study; and (2) patients with terrible and 50 51 52 unstable conditions who were prone to hematoma expansion were 53 54 excluded by investigators privately for fear that deterioration risk would 55 56 57 increase during study. 58 59 60 21

1 2 3 4 Hematoma growth is an independent determinant of death and 5 6 [19] 7 disability. Therefore, hematoma expansion may be an attractive 8 9 therapeutic target.[20, 21] However, no proven specific therapies or 10 11 12 treatments exist to prevent hematoma expansion or improve outcomes 13 14 15 after ICH. Sufficient evidence-based medical research to prove that 16 17 mini-traumatic surgeries and the present available medicines provide 18 For peer review only 19 [6, 7] 20 ideal treatment is lacking. 21 22 23 Herbal medicine in China has been used to treat ICH for at least 2,000 24 25 26 years, and RBS herbal medicines are listed in the 2010 Chinese 27 28 Pharmacopeia.[22] Dr. Si reported the earliest available literature on AICH 29 30 31 with RBS herbal medicine therapy in 1981.[23] Another RBS medicine, 32 33 34 Naoxuekang capsule, was approved as routine treatment for AICH 35 36 patients by the Chinese State Food and Drug Administration [22] 37 38 39 (Naoxuekang capsule, register No. Z10960009). RBS herbal medicines 40 41 have been studied in AICH patients in more than 200 clinical studies over 42 43 44 the past 30 years, and they have gradually come to be considered a 45 46 [24] 47 regular therapy. AICH management guideline in China cited this 48 49 treatment.[25] However, safety evidence in the early stage of AICH is 50 51 52 lacking. Some studies demonstrated that 30% of ICH patients suffered 53 54 continued bleeding within 6 h of onset[26]. Some research has provided 55 56 57 low-level evidence of the safety of RBS herbal medicine for superacute 58 59 60 cerebral hemorrhage, but whether RBS herbal medicine administration in 22

1 2 3 4 an early-stage induced hematoma growth was not known because RBS 5 6 [27] 7 herbal medicine exhibits an anticoagulation effect. Marketed RBS 8 9 drugs that are clinically recognized and widely used did not illustrate a 10 11 12 specific application time window. Early administration of RBS drugs may 13 14 15 cause hematoma expansion and increase the risk of death and serious 16 17 disability. The CRRICH trial was a prospective, double-blinded, 18 For peer review only 19 20 multicenter clinical trial that demonstrated that early administration of 21 22 RBS drugs did not increase hematoma growth but significantly increased 23 24 25 TEAEs. 26 27 28 The CRRICH trial is the largest clinical trial to investigate the safety 29 30 31 and efficacy of a Chinese compound formula in patients with AICH. 32 33 34 Three other influential RCT trials of medical treatments with drugs, 35 36 including FAST, INTERACT2, and CHANT, that exhibit mechanisms 37 38 39 very different from those of RBS used similar methods to evaluate the 40 41 safety and efficacy and found no significant benefit.[28-30] 42 43 44 45 Data from the clinical study suggested that the administration of 46 47 RBS herbal medicine should be avoided in AICH patients during the 48 49 50 initial 6-h time window from stroke onset to avoid the increased risk of 51 52 53 bleeding. Further clinical studies should be performed to confirm the 54 55 safety and efficacy of these agents beyond the 6 h of ICH onset. This 56 57 58 research suggests that the early administration of RBS herbal medicine in 59 60 23

1 2 3 4 ICH patients increases the risk of bleeding, such as gastrointestinal 5 6 7 bleeding, and hematoma growth. Some Chinese patent drugs 8 9 (Naoxuekang capsule (Z10960009), Naoxuekang pill (Z20050312) or 10 11 12 Naoxuekang drop pills (Z10980039)), which primarily consist of Hirudo 13 14 15 nipponica Whitman, should be reevaluated and used under supervision. 16 17 The relevant manufacturers should revise the drug instructions and add a 18 For peer review only 19 20 warning, “Do not use for superacute cerebral hemorrhage within 6 h from 21 22 onset”, if necessary. 23 24 25 26 This study had some limitations. First, there were no available data 27 28 to elucidate the mechanism of TEAEs or serious TEAEs. Second, there 29 30 31 was a significant difference in the number of patients among research 32 33 34 centers. Third, the investigators preferred to study patients with minor 35 36 hematoma volume because they were afraid of the rebleed risk from the 37 38 39 herbal medicine. 40 41 42 Summary 43 44 45 46 This study demonstrates that ultra-early administration, namely, 47 48 within 6 h of ICH onset, of RBS herbal medicine for AICH patients 49 50 51 increased the risk of bleeding, such as gastrointestinal bleeding, and 52 53 hematoma growth. This study also shows that RBS herbal medicine did 54 55 56 not exert significantly beneficial effects on clinical outcomes in 57 58 59 hypertensive ICH patients in the ultra-early stage. These results support 60 24

1 2 3 4 the idea that the ultra-early administration of RBS herbal medicine is 5 6 7 unsafe and has a low efficacy. Future high-quality research should further 8 9 assess the efficacy and safety of herbal medicine for intracerebral 10 11 12 hemorrhage beyond the 6- h time window. 13 14 15 16 17 18 SupplementaryFor Material peer A complete review list of supplementary only material in the CCRICH 19 20 trial is provided in the Supplementary Appendix. 21 22 Data Sharing Statement No additional unpublished data are available. 23 24 Acknowledgments We thank the patients and families who volunteered for this study; 25 26 Zehuai Wen and Ouyang Wen for their assistance with data summarization; and Yubo 27 Lv for his guidance.

1 2 3 removing blood stasis (RBS) herbs hirudo and tabanus) or the ICH-2 4 5 formula (6 herbs without the RBS herbs hirudo and tabanus) within 6 h 6 of ICH onset. 7 8 Outcomes: The primary safety outcome was the incidence of hematoma 9 enlargement at 24 h and at 10 days after treatment. The secondary 10 outcome was the incidence of poor prognosis (mortality or modified 11 12 Rankin Scale (mRS) score ≥5) assessed at 90 days after symptom onset. 13 Results: A total of 324 subjects were randomized between October 2013 14 and May 2016: 105 patients received placebo; 108 patients received the 15 16 ICH-1 formula; and 111 patients received the ICH-2 formula. The 17 incidence of hematoma enlargement at 24 h was 7.8% in the placebo group, 18 12.3% in the ForICH-1 group,peer and 7.5%review in the ICH-2 only group; the incidence of 19 20 hematoma enlargement on day 10 was 1.1% in the placebo group, 1.1% in 21 the ICH-1 group, and 3.1% in the ICH-2 group, with no significant 22 differences among the groups (P>0.05). The mortality rates were 3.8% in 23 24 the placebo group, 2.8% in the ICH-1 group, and 0.9% in the ICH-2 group; 25 the incidences of poor prognosis were 7.1% in the placebo group, 6.0% in 26 the ICH-1 group, and 4.8% in the ICH-2 group at 3 months, with no 27 28 significant differences among the groups (P>0.05). However, the overall 29 frequency of treatment-emergent adverse events(TEAEs) in the ICH-1 30 group (12.1%) was higher among the three groups (5.8% and 2.8%, 31 32 respectively, P<0.05). All 3 cases of serious adverse events were in the 33 ICH-1 group. 34 35 Conclusions: Ultra-early administration of ICH-1formula for AICH 36 patients did not exert significant beneficial effects on clinical outcomes 37 but increased the risk of bleeding, which probably resulted from the 38 39 inclusion of RBS herbal medicines in ICH-1. 40 Clinical Trial Registration: URL:http//www.ClinicalTrials.gov. 41 Unique identifier: NCT01918722. 42 43 Keywords: intracerebral hemorrhage; herbal medicine; randomized 44 controlled trials; hematoma enlargement; CRRICH 45 46 Word count: 4646 47 Strengths and limitations of this study 48 ▪ The CRRICH trial is the largest multicenter clinical trial to examine the 49 50 safety and efficacy of two Chinese compound formulas in patients with 51 AICH. 52 ▪ This study highlights the possibility that the early use of RBS herbal 53 54 medicine in AICH could increase the risk of bleeding, which spurs further 55 research on the safety of Chinese medicines. 56 ▪ There were no available data to elucidate the mechanisms of TEAEs or 57 58 serious TEAEs. 59 60

1 2 3 4 Introduction 5 Acute intracerebral hemorrhage(AICH) accounts for approximately 6 15%[1] of all acute strokes; stroke is the third most common cause of 7 8 death in most Western countries, following coronary heart disease and 9 cancer.[2, 3] AICH has been the leading cause of death in China in recent 10 years[4] and is responsible for approximately one-third of the total number 11 [5] 12 of deaths from stroke worldwide. 13 Available specific medical and surgical treatments do not improve 14 prognosis substantially,[6, 7] and AICH still accounts for a higher 15 [8] 16 proportion of stroke in Chinese people than in white populations. 17 Therefore, traditional Chinese medicine (TCM) physicians in China 18 widely use removingFor peerblood stasis review (RBS) herbs onlyfor the treatment of AICH. 19 20 Meta-analysis showed that RBS herbal therapy for AICH could improve 21 the neurological function deficit, reduce the volume of hematoma and 22 perihematomal edema, and lower the mortality rate and dependency.[9] It 23 24 is possible that RBS herbal medicine promotes hematoma absorption and 25 improves the recovery of neurological impairment[10, 11]; RBS herbal 26 medicine has already been included by guidelines for the management of 27 28 spontaneous ICH. However, sufficient evidence of long-term benefits and 29 risks of superacute stage is lacking. RBS herbals, such as Hirudo 30 nipponica Whitman, which acts as a thrombin inhibitor with 31 32 anticoagulant pharmacological effects, may cause rebleeding risk in 33 clinical practice.[12] A total of 90% of hematoma growth, which plays an 34 important role in prognosis, occurs within a 6-h time window.[13] 35 36 Therefore, a confirmation of the safety and efficacy of RBS herbal 37 medicines in the treatment of early-stage AICH is urgently needed. 38 We performed a retrospective study that demonstrated that RBS 39 [14] 40 herbal medicine for AICH patients was safe and effective. However, 41 little additional evidence of the safety and efficacy of this treatment 42 exists. We designed a multicenter, three-group, prospective, randomized, 43 44 double-blinded and placebo-controlled clinical trial on hematoma 45 enlargement in AICH patients treated with RBS herbal medicine within a 46 47 6-h time window from symptom onset (CRRICH) to evaluate its safety 48 and efficacy in AICH patients and to provide a high level of evidence for 49 clinical practice. 50 51 Methods 52 Study Design 53 The CRRICH trial was a multicenter, randomized, double-blinded, 54 55 placebo-controlled, parallel-group study to assess the safety and efficacy 56 of RBS herbal medicine in AICH patients. This trial is registered at 57 clinicaltrials.gov (NCT01918722), and the research design proposal has 58 [15] 59 been published. 60 Participants

1 2 3 Patients with a Glasgow Coma Scale [GCS] score ≥6 were enrolled 4 5 if they were ≥18 years of age and had a clinical diagnosis of ICH 6 confirmed with computed tomography within 6 h of onset. All 7 8 participants signed an informed consent form. If the participants did not 9 have the capacity to sign the informed consent for serious condition or 10 illiteracy, the researcher will explain the informed consent to the patients 11 12 or their authorized immediate family. Weighing the pros and cons of both 13 sides, their immediate family will decide whether to sign the informed 14 consent on behalf of the patient. Patients who suffered secondary ICH 15 16 resulting from trauma, brain tumor, blood diseases, arteriovenous 17 malformation or aneurysm were excluded. A detailed patient history was 18 recorded. S1 TableFor in peer the online-only review Data Supplement only provides a full list 19 20 of study inclusion and exclusion criteria during the screening period. 21 Randomization and Blinding 22 Patients were randomized to receive placebo, ICH-1, or ICH-2 in 23 24 a 1:1:1 ratio with a stratification and block size of 6 using the PROC 25 PLAN process in SAS software version 9.13. Stratified block and 26 randomization were concealed using sequentially numbered opaque 27 28 envelopes. Persons involved in the study, including the investigators, 29 patients and data analysts, were blinded to treatment assignment during 30 double-blinded treatment until the end of follow-up. Only the data 31 32 administrators were permitted access to unblinded data. 33 Procedures 34 Enrollment, Intervention and Follow-up 35 Patients were recruited from October 2013 through May 2016 at 14 36 37 hospitals in China (S2 Table in the online-only Data Supplement). The 38 study consisted of a screening and randomization period (≤6 h 39 40 poststroke), a 10-day double-blinded treatment period and a 3-month 41 follow-up period (S1 Figure in the online-only Data Supplement). 42 Participants were randomly assigned to one of three treatment groups at a 43 44 ratio of 1:1:1 during the double-blinded treatment (shown in the S3 and 45 S4 Table in the online-only Data Supplement): (1) The ICH-1 group 46 received the ICH-1 formula, which consisted of 8 herbs including RBS 47 48 medicines; (2) The ICH-2 group received the ICH-2 formula, which 49 consisted of 6 herbal medicines without RBS herbs(Hirudo nipponica 50 Whitman and Tabanus bivittatus Matsumura) in the same doses as those 51 52 in the ICH-1 group, with the remaining dose filled with a placebo; and (3) 53 The placebo group received a placebo that included dextrin and farina. 54 Each unit of TCM medicine or placebo was dissolved in 200 ml of 55 56 boiling water. Each patient received 200 ml orally or through a 57 nasogastric tube two times daily for 10 days (S3 Table in the online-only 58 Data Supplement). 59 60 Patients were followed up for 3 months after the 10-day double-

1 2 3 blinded treatment period. Patients were hospitalized in stroke units and 4 5 received standard stroke care in accordance with local guidelines, which 6 included general supportive care, treatment of acute complications, and 7 8 rehabilitation. Astringents and other RBS drugs were prohibited. Visits 9 were scheduled at baseline, 24 h poststroke, and at the end of the 10 treatment period, with a single visit scheduled 3 months poststroke (S1 11 12 Figure in the online-only Data Supplement). Adverse events (AEs), 13 treatment compliance, and concomitant medication use were reported 14 during each visit. Participants were randomly assigned to one of three 15 16 treatment groups at a ratio of 1:1:1 during double-blinded treatment. 17 Primary and Secondary Outcomes 18 The incidenceFor of peer hematoma review enlargement, onlywhich was defined as the 19 20 percentage of participants who experienced hematoma enlargement, was 21 the primary outcome of the study. Hematoma enlargement was 22 operationally defined as an increase in hematoma volume of >33% or 23 24 12.5 ml, as measured on image analysis on the 24-h CT compared with 25 the baseline CT scan. Hematoma volume was measured using the ABC/2 26 Coniglobus formula[16] at 24 h after onset. The same measurement was 27 28 performed on days 10-14 as a primary outcome measure. 29 NIHSS(National Institutes of Health Stroke Scale) scores range from 0 30 (normal) to 42 (coma with quadriplegia); and mRS(modified Rankin 31 32 Scale) scores range from 0 (no symptoms or disability) to 6 (death). Both 33 of them can be used to evaluate the clinical outcomes.The following 34 secondary end points were assessed: change in NIHSS score at 3 months; 35 36 mortality at 3 months; and poor prognosis rate, which was defined as the 37 proportion of patients who died or were severely disabled based on an 38 mRS score ≥5 at 3 months.[17] Safety data focused on treatment-emergent 39 40 AEs (TEAEs). TEAEs were defined as AEs that first occurred or 41 worsened (increased in severity) after the first dose of study drug. The 42 patient spontaneously reported TEAEs in response to an open-ended 43 44 question from the contact person at each visit. A worsened patient 45 condition, prolonged patient hospitalization, and life-threatening TEAEs 46 in patients were reported as serious adverse events (TEsAEs). Abnormal 47 48 laboratory values that constituted a serious AE or led to the 49 discontinuation of experimental drugs were also reported as TEsAEs. S5 50 Table in the online-only Data Supplement provides a full list of all 51 52 primary, secondary and safety end points. 53 Statistical Analyses 54 All reported efficacy analyses were predefined and based on the full 55 56 analysis set (FAS) (patients who were randomized and received any study 57 medication) according to the intent-to-treat (ITT) principle. Supportive 58 analyses were performed in a predefined per-protocol population set 59 60 (PPS), which included FAS patients who did not have one or more key

1 2 3 protocol deviations, including violations of inclusion and exclusion 4 5 criteria. The last observation for surviving patients with missing outcome 6 data was carried forward. Patients who had died by the 90-day follow-up 7 8 were assigned a Barthel index score of 0 and an mRS score of 6, and the 9 last recorded NIHSS score was carried forward. The incidence of 10 hematoma enlargement at 24 h (primary end point), the rate of poor 11 12 prognosis and the incidence of total TEAEs among the three groups were 2 13 analyzed using the χ test. The incidence of hematoma enlargement on 14 days 10-14 (primary end point) and mortality among the three groups 15 16 were compared using Fisher’s exact test. The mean differences in NIHSS 17 score among groups were analyzed using one-way ANOVA. 18 DemographicFor characteristics peer and review serious TEAEs only were summarized using 19 20 descriptive statistics. 21 Power and sample size were determined using relative hematoma 22 volume at 24 h as the primary outcome variable. A total of 285 23 24 participants were required at the final follow-up to provide 90% power 25 with a two-sided alpha level at 0.05 to test the primary efficacy, which 26 was calculated using the PASS (Power Analysis and Sample Size) 27 28 software program (licensed by NCSS, LLC). A total of 360 participants 29 were needed for primary outcome randomization assuming a dropout rate 30 of 20%, with 120 patients per treatment arm. The statistical package 31 32 STATA (version 13.1) was used for all statistical analyses. 33 Patient and Public Involvement Statement 34 While we put forward the research question and outcome measures, 35 36 the patients’ priorities, experience, and preferences were fully considered 37 by a survey. Patients were involved in the recruitment to and conduct of 38 the study. The results would be disseminated to study participants by 39 40 posting a letter. The CRRICH trial was a randomized controlled trial, and 41 the patients themselves had fully assessed the burden of the intervention. 42 Patient advisors should also be thanked in the contributorship 43 44 statement/acknowledgments. 45 Funding and Ethical Statements 46 The State Administration of Traditional Chinese Medicine of the 47 48 P.R.C.

All patients provided written informed 7 8 consent to participate in the study. An independent contract research 9 organization, S&R (Department of Science and Research of Guangdong 10 Provincial Hospital of Chinese medicine), managed the administration, 11 12 coordination, and monitoring of the study, including researcher training, 13 study inspection, data management and statistical analyses, with 14 oversight by the State Administration of Traditional Chinese Medicine of 15 16 the P.R.C. 17 Results 18 Study PopulationFor peer review only 19 20 Patient recruitment began in October 2013, and the study ended in 21 May 2016. A total of 5589 individuals with ICH were screened (Figure 22 1). The most frequent reasons for exclusion in descending order were 23 24 time window >6 h, refusal to participate, secondary ICH (i.e., not AICH) 25 and other reasons. A total of 319 of the 324 randomized patients (105 26 placebo, 108 ICH-1, 111 ICH-2) received the assigned treatment 27 28 following the elimination of five patients (one patient for missing the 29 time window, one patient for kidney failure, one patient for secondary 30 ICH, one patient for surgery within 24 h and one patient withdrew 31 32 consent). Therefore, only the 319 participants who underwent 33 randomization and received study medication were included in the FAS 34 and safety analysis set based on ITT. Twenty-three patients in the FAS 35 36 did not completely adhere to the protocol and dropped out during the 37 treatment period. A total of 296 patients were included in the PPS (see 38 Figure 1 for patient flow diagram). The mean dropout rate was <8%. 39 40 Table 1 presents the demographics and baseline characteristics of the 41 FAS, which were well balanced with no significant between-group 42 differences. The mean age was 62.5±12.7 years (mean±SD, n=319); 43 44 65.5% of the patients were male, and 98.7% were ethnic Han. The 45 median GCS score was 15 (range, 3 to 15), and the mean NIHSS score 46 was 8 (range, 0 to 47). The deep gray matter was involved in 93.4% of 47 48 cases, and the lobar regions were involved in 6.6% of cases. The baseline 49 characteristics of the three treatment groups were similar. The mean 50 volume of the ICH at baseline for all patients was 11.0 ml (range, 0.3 to 51 52 86.7 ml), which was similar in the three groups (Table 1). The mean time 53 from onset of symptoms to admission was 3.36±1.49 h, and the mean 54 time from onset of symptoms to treatment was 4.10±1.38 h. Fourteen 55 56 percent of patients were treated within 3 h after symptom onset. Two 57 patients were treated outside of the 6-h time window. The timing of the 58 59 treatment was similar in the three groups (Table 1). 60

The incidence of hematoma enlargement were 7.8% 21 in the placebo group, 12.3% in the ICH-1 group and 7.5% in the ICH-2 22 group. There was no significant difference in the incidence of hematoma 23 24 enlargement at 24 h among the three groups (P=0.409). The incidence of 25 hematoma enlargement on days 10-14 was 1.1% in the placebo group, 26 3.1% in the ICH-2 group and 1.1% in the ICH-1 group. There was also no 27 28 significant difference among the three groups in the incidence of hematoma 29 enlargement on days 10-14 (P=0.625) (Table 2). 30 Secondary Outcomes (Clinical Outcomes) 31 32 Mortality at 3 months was approximately 2.6% in the three groups 33 (Table 2). Poor prognosis (i.e., the proportion of patients who died or 34 were severely disabled, mRS ≥5) did not differ significantly among the 35 36 three groups. It is the least patients of poor prognosis occurred in the 37 ICH-2 treatment, but no statistical difference compared with placebo 38 treatment (Table 2). The distributions of outcomes on the modified 39 40 Rankin Scale (Figure 2) were similar among the three groups. The 41 differences in the NIHSS scores at 3 months among the three groups were 42 not significant (Table 2). 43 44 45 Figure2 Clinical Outcome at 90 Days According to the Modified Rankin Scale. The modified Rankin Scale 46 evaluates global disability and handicap. Scores range from 0 (no symptoms or disability) to 6 (death). There were no significant differences among the three groups. 47 48 49 Adverse Events 50 There were altogether 35 AEs reported by investigators, of which 22 51 AEs may have been TEAEs. All the TEAEs occurred during the double- 52 53 blinded treatment period (within 2 weeks). TEAEs occurred in 13 54 (12.1%) ICH-1-treated patients, 3 (2.8%) ICH-2-treated patients and 6 55 (5.8%) placebo-treated patients. The patterns of TEAEs were similar in 56 57 the 3 groups, but the overall frequencies of TEAEs among the three 58 groups were significantly different (P=0.022), as shown in Table 2. And 59 the paired comparisons showed that the test for difference in the overall 60

1 2 3 TEAEs rate between group ICH-1 and group ICH-2 yields a p-value of 4 5 0.029. Table 3 shows the TEAEs that occurred during the study. The most 6 frequent event was diarrhea, and its incidence was similar in the 3 7 8 treatment groups . Treatment was discontinued because of TEsAEs in 3 9 (1.9%) ICH-1-treated patients. The 3 cases with TEsAEs (2 cases of 10 gastrointestinal bleeding, 1 case of cerebral hernia) reported by 11 12 investigators occurred in ICH-1-treated patients. There was no consistent 13 pattern to this difference, and all serious TEAEs occurred within the 10- 14 day drug treatment period. There were no statistically significant 15 16 differences in the incidence or type of serious TEAEs leading to death 17 among groups (data not shown). There was no relationship between 18 TEAEs, seriousFor TEAEs, peer or mortality review and poor outcomeonly (data not shown). 19 20 Table 2 Primary outcome and secondary outcomes 21 22 Differences 23 Placebo ICH-2 ICH-1 Among Groups 24 P Value 25 26 Primary outcome: the incidence of hematoma enlargement at 24 h and at day 14 27 28 At 24 h 8/104(7.8) 8/108(7.5) 13/107(12.3) 0.409 29 30 On days 10-14 1/92(1.1) 3/97(3.1) 1/91(1.1) 0.625 31 Hemorrhage Volumes(ml)at Baseline and Follow-up 32 33 At baseline 9.82±7.45 11.56±9.67 11.57±11.55 0.284 34 35 At 24 h 9.71±6.94 11.97±10.02 14.44±19.33 0.313 36 37 percent increase from 38 baseline- means% (95% -14.1(4.5-32.7) 3.4(0.2-6.5) 41(9.4-91.4) 0.22 39 CI) 40 milliliters of increase -0.13±1.41 0.22±2.24 3.13±16.10 0.168 41 from baseline 42 43 Secondary outcomes: 44 # 45 NIHSS at 3 months 3.58±5.32 3.58±5.32 3.58±5.32 0.475 46 Mortality at 3 months 4/104(3.8) 1/108(0.9) 3/107(2.8) 0.328 47 48 Poor prognosis (mRS 0.783 7/99(7.1) 5/105(4.8) 6/100(6.0) 49 ≥5) 50 51 Total TEAEs 6/104(5.8) 3/108(2.8) 13/107(12.1) 0.022 52 The values are expressed as n/N(%) within group or the means±SD; # denotes the number of patients at 3 months: 53 104 in the placebo group, 107 in the ICH-2 group, and 105 in the ICH-1 group. 54 55 56 57 58 59 60

Conversely, compared to the ICH-2, 35 36 the incidence of TEAEs showed an increasing trend in the ICH-1 group 37 38 (P= 0.029, ICH-1vs. ICH-2). Significant increases were also 39 40 demonstrated in total TEAE frequency and in serious TEAEs in the ICH- 41 42 1 group. Three serious bleeding events occurred in the ICH-1 group 43 44 (ICH-1, with 2 RBS herbals), including two cases of gastrointestinal 45 46 bleeding and one case of intracerebral rebleeding. All three cases were 47 48 fatal serious TEAEs (Table 2). These data suggest that RBS treatment for 49 50 ICH patients within 6 h of symptom onset is a safety concern. However, 51 52 no data were available to suggest a mechanism for this effect. The 53 54 possible rebreeding mechanism is that RBS medicine, such as Hirudo 55 56 nipponica Whitman, which has anticoagulant pharmacological effects, 57 [12] 58 could increase bleeding risk according to the previous literature. 59 60 As can be seen from the table 2, ICH-2 treatment

1 2 3 was least vulnerable to poor prognosis and TEAEs. Therefore, ICH-2 4 5 6 formula would have the potential to be an effective herbal drug for ICH 7 8 patients of superacute stage. 9 10 This result contrasts with the clinical benefit demonstrated in a 11 [9] 12 previous meta-analysis , which included 9 randomized controlled 13 14 clinical trials with 798 individuals, demonstrating that RBS therapy for 15 16 acute ICH reduced brain hematoma and cerebral edema volumes, 17 18 improved the Forneural functionpeer and review reduced the mortalityonly and disability 19 20 rates with fewer TEAEs. The present trial revealed significant 21 22 heterogeneity compared with the studies included in the meta-analysis, 23 24 possibly because of differences in the intervention time window. This 25 26 research is the first prospective, multicenter, randomized, double-blind, 27 28 placebo-controlled study to assess the efficacy and safety of ICH-1 in 29 30 AICH patients within a 6-h time window from symptom onset, unlike 31 32 prior studies that examined these effects within a 24-h or later 33 34 intervention time window. Earlier RBS administration increased the risk 35 36 of bleeding events (e.g., gastrointestinal bleeding or intracerebral 37 38 rebleeding), which counteracted the benefit to some extent. 39 40 The primary outcome of the incidence of hematoma enlargement, 41 42 which is an independent prognostic determinant of mortality and poor 43 [18] 44 prognosis, was also used to assess safety. The incidence of hematoma 45 46 enlargement at 24 h in the three groups in the CRRICH trial (placebo, 47 48 ICH-2, and ICH-1) were 7.8%, 7.5%, and 12.3%, respectively, and they 49 50 were not significantly different (Table 2). The mean incidence of 51 52 hematoma enlargement was only 9.2%, which was far lower than the 53 [18] 54 mean level of 18-30%. The main reasons for lower hematoma 55 56 expansion incidence may include the following: (1) the investigators’ 57 58 inclination toward surgery in AICH patients with large hemorrhage 59 60 volumes within 24 h of onset, which resulted in the exclusion of patients

1 2 3 susceptible to rebleed in the study; and (2) patients with terrible and 4 5 6 unstable conditions who were prone to hematoma expansion were 7 8 excluded by investigators privately for fear that deterioration risk would 9 10 increase during study. 11 12 Hematoma growth is an independent determinant of death and 13 [19] 14 disability. Therefore, hematoma expansion may be an attractive 15 [20, 21] 16 therapeutic target. However, no proven specific therapies or 17 18 treatments existFor to prevent peer hematoma review expansion only or improve outcomes 19 20 after ICH. Sufficient evidence-based medical research to prove that mini- 21 22 traumatic surgeries and the present available medicines provide ideal 23 [6, 7] 24 treatment is lacking. 25 26 Herbal medicine in China has been used to treat ICH for at least 2,000 27 28 years, and RBS herbal medicines are listed in the 2010 Chinese 29 [22] 30 Pharmacopeia. Dr. Si reported the earliest available literature on AICH 31 [23] 32 with RBS herbal medicine therapy in 1981. Another RBS medicine, 33 34 Naoxuekang capsule, was approved as routine treatment for AICH 35 [22] 36 patients by the Chinese State Food and Drug Administration 37 38 (Naoxuekang capsule, register No. Z10960009). RBS herbal medicines 39 40 have been studied in AICH patients in more than 200 clinical studies over 41 42 the past 30 years, and they have gradually come to be considered a 43 [24] 44 regular therapy. AICH management guideline in China cited this 45 [25] 46 treatment. However, safety evidence in the early stage of AICH is 47 48 lacking. Some studies demonstrated that 30% of ICH patients suffered 49 [26] 50 continued bleeding within 6 h of onset . Some research has provided 51 52 low-level evidence of the safety of RBS herbal medicine for superacute 53 54 cerebral hemorrhage, but whether RBS herbal medicine administration in 55 56 an early-stage induced hematoma growth was not known because RBS 57 [27] 58 herbal medicine exhibits an anticoagulation effect. Marketed RBS 59 60 drugs that are clinically recognized and widely used did not illustrate a

1 2 3 specific application time window. Early administration of RBS drugs 4 5 6 may cause hematoma expansion and increase the risk of death and serious 7 8 disability. The CRRICH trial was a prospective, double-blinded, 9 10 multicenter clinical trial that demonstrated that early administration of 11 12 RBS drugs did not increase hematoma growth but significantly increased 13 14 TEAEs. 15 16 The CRRICH trial is the largest clinical trial to investigate the safety 17 18 and efficacy ofFor a Chinese peer compound review formula in only patients with AICH. 19 20 Three other influential RCT trials of medical treatments with drugs, 21 22 including FAST, INTERACT2, and CHANT, that exhibit mechanisms 23 24 very different from those of RBS used similar methods to evaluate the 25 [28-30] 26 safety and efficacy and found no significant benefit. 27 28 Data from the clinical study suggested that the administration of 29 30 RBS herbal medicine should be avoided in AICH patients during the 31 32 initial 6-h time window from stroke onset to avoid the increased risk of 33 34 bleeding. Further clinical studies should be performed to confirm the 35 36 safety and efficacy of these agents beyond the 6 h of ICH onset. This 37 38 research suggests that the early administration of RBS herbal medicine in 39 40 ICH patients increases the risk of bleeding, such as gastrointestinal 41 42 bleeding, and hematoma growth. Some Chinese patent drugs 43 44 (Naoxuekang capsule (Z10960009), Naoxuekang pill (Z20050312) or 45 46 Naoxuekang drop pills (Z10980039)), which primarily consist of Hirudo 47 48 nipponica Whitman, should be reevaluated and used under supervision. 49 50 The relevant manufacturers should revise the drug instructions and add a 51 52 warning, “Do not use for superacute cerebral hemorrhage within 6 h from 53 54 onset”, if necessary. 55 56 This study had some limitations. First, there were no available data 57 58 to elucidate the mechanism of TEAEs or serious TEAEs. Second, there 59 60 was a significant difference in the number of patients among research

1 2 3 centers. Third, the investigators preferred to study patients with minor 4 5 6 hematoma volume because they were afraid of the rebleed risk from the 7 8 herbal medicine. 9 10 Summary 11 12 This study demonstrates that ultra-early administration, namely, 13 14 within 6 h of ICH onset, of RBS herbal medicine for AICH patients 15 16 increased the risk of bleeding, such as gastrointestinal bleeding, and 17 18 hematoma growth.For This peer study also review shows that RBSonly herbal medicine did 19 20 not exert significantly beneficial effects on clinical outcomes in 21 22 hypertensive ICH patients in the ultra-early stage. These results support 23 24 the idea that the ultra-early administration of RBS herbal medicine is 25 26 unsafe and has a low efficacy. Future high-quality research should further 27 28 assess the efficacy and safety of RBS herbal medicine for intracerebral 29 30 hemorrhage beyond the 6- h time window. 31 32 33 Supplementary Material A complete list of supplementary material in the CCRICH 34 trial is provided in the Supplementary Appendix. 35 Data Sharing Statement No additional unpublished data are available. 36 Acknowledgments We thank the patients and families who volunteered for this 37 38 study; Zehuai Wen and Ouyang Wen for their assistance with data summarization; 39 and Yubo Lv for his guidance.
