Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to Parasite Clearance
Time Frame: Day 5
Parasite clearance was determined by assessing the parasite count in blood, using thin film, thick film and blood density assessments.
Day 5
28-day Cure Rate - Part 2
Time Frame: Day 28
28-day cure rate was defined as the percentage of participants with blood parasite count of zero after 28 days of treatment.

Secondary Outcome Measures
