Clinical trial

Phase IIa Proof of Concept, Multicenter, Randomized, Open-label Study to Evaluate the Safety, Efficacy, and Pharmacokinetics of the Combination M5717 Plus Pyronaridine Administered Once Daily for 1 or 2 Days to Adults and Adolescents With Acute Uncomplicated Plasmodium Falciparum Malaria (CAPTURE 1)

Name
MS201618_0033
Description
The purpose of this study is to evaluate the safety, efficacy, and pharmacokinetic of the combination M5717 plus pyronaridine in participants with acute uncomplicated Plasmodium falciparum malaria. Pyramax (Artesunate/Pyronaridine) will act as an internal control providing reference safety data and a benchmark for the efficacy evaluation.
