Rivaroxaban Versus Warfarin for Treatment and Prevention Of
Costa et al. Thrombosis Journal (2020) 18:6 https://doi.org/10.1186/s12959-020-00219-w RESEARCH Open Access Rivaroxaban versus warfarin for treatment and prevention of recurrence of venous thromboembolism in African American patients: a retrospective cohort analysis Olivia S. Costa1,2, Stanley Thompson3, Veronica Ashton4, Michael Palladino5, Thomas J. Bunz6 and Craig I. Coleman1,2* Abstract Background: African Americans are under-represented in trials evaluating oral anticoagulants for the treatment of acute venous thromboembolism (VTE). The aim of this study was to evaluate the effectiveness and safety of rivaroxaban versus warfarin for the treatment of VTE in African Americans. Methods: We utilized Optum® De-Identified Electronic Health Record data from 11/1/2012–9/30/2018. We included African Americans experiencing an acute VTE during a hospital or emergency department visit, who received rivaroxaban or warfarin as their first oral anticoagulant within 7-days of the acute VTE event and had ≥1 provider visit in the prior 12-months. Differences in baseline characteristics between cohorts were adjusted using inverse probability-of-treatment weighting based on propensity scores (standard differences < 0.10 were achieved for all covariates). Our primary endpoint was the composite of recurrent VTE or major bleeding at 6-months. Three- and 12-month timepoints were also assessed. Secondary endpoints included recurrent VTE and major bleeding as individual endpoints. Cohort risk was compared using Cox regression and reported as hazard ratios (HRs) with 95% confidence intervals (CIs). Results: We identified 2097 rivaroxaban and 2842 warfarin users with incident VTE. At 6-months, no significant differences in the composite endpoint (HR = 0.96, 95%CI = 0.75–1.24), recurrent VTE (HR = 1.02, 95%CI = 0.76–1.36) or major bleeding alone (HR = 0.93, 95%CI = 0.59–1.47) were observed between cohorts. -

Subsequent studies have shown that surfen can indicated that surfen bound to glycosaminoglycans, and the extent block C5a receptor binding (17) and lethal factor (LF) produced of binding increased according to charge density in the order by anthrax (18). It was also reported to have modest heparin- heparin > dermatan sulfate > heparan sulfate > chondroitin neutralizing effects in an oral feeding experiments in rats (19), sulfate.

ANNEX I SUMMARY OF PRODUCT CHARACTERISTICS 1 1. NAME OF THE MEDICINAL PRODUCT Kengrexal 50 mg powder for concentrate for solution for injection/infusion 2. QUALITATIVE AND QUANTITATIVE COMPOSITION Each vial contains cangrelor tetrasodium corresponding to 50 mg cangrelor. After reconstitution 1 mL of concentrate contains 10 mg cangrelor. After dilution 1 mL of solution contains 200 micrograms cangrelor. Excipient with known effect Each vial contains 52.2 mg sorbitol. For the full list of excipients, see section 6.1. 3. PHARMACEUTICAL FORM Powder for concentrate for solution for injection/infusion. White to off-white lyophilised powder. 4. CLINICAL PARTICULARS 4.1 Therapeutic indications Kengrexal, co-administered with acetylsalicylic acid (ASA), is indicated for the reduction of thrombotic cardiovascular events in adult patients with coronary artery disease undergoing percutaneous coronary intervention (PCI) who have not received an oral P2Y12 inhibitor prior to the PCI procedure and in whom oral therapy with P2Y12 inhibitors is not feasible or desirable. 4.2 Posology and method of administration Kengrexal should be administered by a physician experienced in either acute coronary care or in coronary intervention procedures and is intended for specialised use in an acute and hospital setting. Posology The recommended dose of Kengrexal for patients undergoing PCI is a 30 micrograms/kg intravenous bolus followed immediately by 4 micrograms/kg/min intravenous infusion. The bolus and infusion should be initiated prior to the procedure and continued for at least two hours or for the duration of the procedure, whichever is longer. At the discretion of the physician, the infusion may be continued for a total duration of four hours, see section 5.1. -
The Evolving Role of Direct Thrombin Inhibitors in Acute Coronary

PII S0735-1097(02)02687-6 The Evolving Role of Direct Thrombin Inhibitors in Acute Coronary Syndromes John Eikelboom, MBBS, MSC, FRACP, FRCPA,* Harvey White, MB, CHB, DSC, FRACP, FACC,† Salim Yusuf, MBBS, DPHIL, FRCP (UK), FRCPC, FACC‡ Perth, Australia; Auckland, New Zealand; and Hamilton, Ontario, Canada The central role of thrombin in the initiation and propagation of intravascular thrombus provides a strong rationale for direct thrombin inhibitors in acute coronary syndromes (ACS). Direct thrombin inhibitors are theoretically likely to be more effective than indirect thrombin inhibitors, such as unfractionated heparin or low-molecular-weight heparin, because the heparins block only circulating thrombin, whereas direct thrombin inhibitors block both circulating and clot-bound thrombin. Several initial phase 3 trials did not demonstrate a convincing benefit of direct thrombin inhibitors over unfractionated heparin. However, the Direct Thrombin Inhibitor Trialists’ Collaboration meta-analysis confirms the superiority of direct thrombin inhibitors, particularly hirudin and bivalirudin, over unfractionated heparin for the prevention of death or myocardial infarction (MI) during treatment in patients with ACS, primarily due to a reduction in MI (odds ratio, 0.80; 95% confidence interval, 0.70 to 0.91) with little impact on death. The absolute risk reduction in the composite of death or MI at the end of treatment (0.8%) was similar at 30 days (0.7%), indicating no loss of benefit after cessation of therapy. -

The presentations include several containing benzyl alcohol as a preservative and one preservative-free presentation. The first cycle review of the NDA found the application acceptable from a clinical viewpoint. However, manufacturing facilities inspection identified deficiencies that precluded approval and a Complete Response (CR) letter was issued on April 7, 2011. Labeling review was not completed at that time. In the current resubmission the sponsor has responded to the identified deficiencies deleting the two heparin supplier sites where deficiencies were found.
