Measure Type Secondary
Measure Title Number of Participants With Day 28 Adequate Clinical and Parasitologic Response in Each Treatment Arm
Measure Description Adequate clinical and parasitologic response (ACPR) was defined as the absence of parasitemia at Day 28 and without previously meeting any of the criteria of early treatment or late clinical failure.
Time Frame Day 28 of third subsequent malaria episode (Episode 3)  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
This analysis was per protocol, which includes participants who had at least 3 subsequent malaria episodes, but excludes participants if the third episode was not caused by p. falciparum or if the participant did not receive all 3 doses of treatment for the third episode.

unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.


Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
