Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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
Minimum Inhibitory Concentration (MIC) of KAE609
Time Frame: Up to Day 8 after a single dose of KAE609
To observe the exposure-response (PK/PD) relationship for a single dose of KAE609. The key parameter is MIC, defined as the concentration at which the relative rate of change in parasitemia is equal to zero. Approximation of MIC will assist in identifying the optimal dose of KAE609, which will be one component of a future combination antimalarial. MIC could not be determined due to small sample size no data was collected from any participants.
Up to Day 8 after a single dose of KAE609

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Median Time to Parasite Clearance
Time Frame: pre-dose, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 24, 30, 36, 42, 48, 54, 60, 66, 72 hours post dose of KAE609
Parasite clearance time will be estimated using thick/thin blood films.
pre-dose, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 24, 30, 36, 42, 48, 54, 60, 66, 72 hours post dose of KAE609
Median Time to Fever Clearance
Time Frame: Day 1 to Day 5
Fever is monitored on participants every 4 hours for the first 24 hours, then every 6 hours until negative reading obtained.
Day 1 to Day 5
Percentage of Patients PCR-corrected Cure Rate by Day 28, Day 35 & Day 42
Time Frame: Day 28, Day 35 & Day 42
PCR-corrected cure rate after a single dose of KAE609 by Day 28, Day 35 & Day 42. PCR-corrected cure rate accounts for failures due to reappearance of parasites that were present in the blood before treatment (i.e. recrudescent infection) but not for failures due to a post-treatment inoculation (i.e. new infection).
Day 28, Day 35 & Day 42
