WHO Launches Clinical Trial for Ebola Treatments
- Trial Launch: The WHO has initiated a clinical trial in Congo's Ituri province to evaluate Mapp Biopharmaceutical's monoclonal antibody MBP134 and Gilead's antiviral remdesivir, aimed at improving treatment for the rare Bundibugyo Ebola strain.
- Patient Recruitment: The study plans to enroll several hundred patients, with participants randomly assigned to receive either a single-dose infusion of MBP134, daily remdesivir for up to 10 days, a combination of both treatments, or optimized supportive care to assess treatment efficacy.
- Flexible Trial Design: Structured as an adaptive platform trial, it can continue through future Ebola outbreaks, ensuring conclusive results can be generated even if the current epidemic ends before sufficient patient enrollment.
- Primary and Secondary Endpoints: The primary endpoint focuses on all-cause mortality 28 days post-enrollment, while secondary endpoints include viral clearance, changes in viral load, organ function, and pregnancy outcomes, with special monitoring for pregnant participants to ensure maternal and infant safety.
