Fexinidazole – New Orphan Drug Approval
Fexinidazole – New orphan drug approval • On July 19, 2021, Sanofi announced the FDA approval of fexinidazole, for the treatment of both the first-stage (hemolymphatic) and second-stage (meningoencephalitic) human African trypanosomiasis (HAT) due to Trypanosoma brucei gambiense (T. brucei gambiense) in patients 6 years of age and older and weighing at least 20 kg. — Due to the decreased efficacy observed in patients with severe second stage HAT (cerebrospinal fluid white blood cell count > 100 cells/µL) due to T. brucei gambiense disease, fexinidazole should only be used in these patients if there are no other available treatment options. • Sleeping sickness is a parasitic disease transmitted by the bite of an infected tse-tse fly. It affects mostly populations living in remote rural areas of sub-Saharan Africa. Left untreated, sleeping sickness is almost always fatal. — According to the CDC, less than 100 cases of sleeping sickness have been reported annually to the World Health Organization. Infection of international travelers is rare, but it occasionally occurs and most cases of sleeping sickness imported into the U.S. have been in travelers who were on safari in East Africa. • The efficacy of fexinidazole was established in a randomized, comparative open-label trial in 394 adult patients with late second-stage HAT due to T. brucei gambiense. Patients were randomized to a 10-day treatment regimen of either fexinidazole or nifurtimox-eflornithine combination therapy (NECT). The outcome at 18 months was considered a success if patients were classified as a cure or probable cure. — Success at 18 months was achieved in 91.2% of patients treated with fexinidazole vs. -

Human African trypanosomiasis (HAT) can affect travelers to sub-Saharan Africa, as well as migrants from disease endemic countries (DECs), posing diagnosis challenges to travel health services in non-disease endemic countries (non-DECs). Methods. Cases reported in journals have been collected through a bibliographic research and complemented by cases reported to the World Health Organization (WHO) during the process to obtain anti-trypanosome drugs. These drugs are distributed to DECs solely by WHO. Drugs are also provided to non-DECs when an HAT case is diagnosed. However, in non-DEC pentamidine can also be purchased in the market due to its indication to treat Pneumocystis and Leishmania infections. Any request for drugs from non-DECs should be accompanied by epidemiological and clinical data on the patient. Results. During the period 2000 to 2010, 94 cases of HAT were reported in 19 non-DECs. Seventy-two percent of them corresponded to the Rhodesiense form, whereas 28% corresponded to the Gambiense. Cases of Rhodesiense HAT were mainly diagnosed in tourists after short visits to DECs, usually within a few days of return. -

Nifurtimox-Eflornithine Combination Therapy for Second-Stage
MAJOR ARTICLE Nifurtimox-Eflornithine Combination Therapy for Second-Stage Gambiense Human African Trypanosomiasis: Médecins Sans Frontières Experience in the Democratic Republic of the Congo Emilie Alirol,1,2,a David Schrumpf,1,2,a Josué Amici Heradi,2 Andrea Riedel,2 Catherine de Patoul,2 Michel Quere,2 and François Chappuis1,2 1 2 Division of International and Humanitarian Medicine, University Hospitals of Geneva, and Médecins Sans Frontières, Operational Centre Geneva, Downloaded from Switzerland Background. Existing diagnostic and treatment tools for human African trypanosomiasis (HAT) are limited. The recent development of nifurtimox-eflornithine combination therapy (NECT) has brought new hopes for pa- tients in the second stage. While NECT has been rolled out in most endemic countries, safety data are scarce and derive only from clinical trials. The World Health Organization (WHO) coordinates a pharmacovigilance program http://cid.oxfordjournals.org/ to collect additional data on NECT safety and efficacy. We report here the results of 18 months of experience of NECT use in treatment centers run by Médecins Sans Frontières in the Democratic Republic of the Congo (DRC). Methods. This cohort study included 684 second-stage HAT patients (including 120 children) treated with NECT in Doruma and Dingila hospitals, northeastern DRC, between January 2010 and June 2011. All treatment- emergent adverse events (AEs) were recorded and graded according to the Common Terminology Criteria for Adverse Events version 3.0. Safety and efficacy data were retrieved from the WHO pharmacovigilance forms and from Epitryps, a program monitoring database. by guest on June 13, 2014 Results. Eighty-six percent of the patients experienced at least 1 AE during treatment. -
