Clinical Trial Summary

This Phase 2a trial recruits adult patients with uncomplicated P. vivax or P. falciparum blood-stage malaria mono-infection. The study drug SJ733 will be administered to examine its antimalarial efficacy, safety, and tolerability. This study also evaluates whether or not a fixed dose of the pharmacoenhancer cobicistat when given in combination with SJ733 significantly improves drug efficacy.


Clinical Trial Description

This is an adaptive open label Phase 2a study to examine the antimalarial efficacy, safety, and tolerability of SJ733 in adult patients with uncomplicated P. vivax or P. falciparum blood-stage malaria monoinfection. SJ733 will be administered orally once every day for three consecutive days, with or without a fixed dose of the pharmacoenhancer cobicistat. The Phase 1 clinical data (completed under a US IND) and PK/PD models suggest that SJ733 is most likely to be curative as a 3-daily-dose pharmacoenhanced therapy, due to its moderately rapid clearance. There will be 1-3 cohorts with each cohort containing two treatment arms, P. falciparum (a) and P. vivax (b). Cohort progression will be managed independently for each treatment arm. Interim analysis will determine whether the data for a given treatment arm meets the success criteria, is inconclusive, or meets the failure criteria. Antimalarial efficacy will be examined over the period of 42 days. Additional aims are to characterize the safety and pharmacokinetics of SJ733. The results of this trial will identify active, well-tolerated doses for investigation in a larger Phase 2b clinical trial. ;
