Trial Outcomes & Findings for A Study to Find the Minimum Inhibitory Concentration of KAE609 in Adult Male Patients With P. Falciparum Monoinfection (NCT NCT01836458)

NCT ID: NCT01836458

Last Updated: 2016-10-31

Results Overview

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.

PRIMARY outcome

Timeframe: Up to Day 8 after a single dose of KAE609

Population: The primary Outcome Measure (OM) could not be determined due to small sample size no data was collected from any participants.

Population: Pharmacodynamic Analysis Set includes all enrolled patients

Fever is monitored on participants every 4 hours for the first 24 hours, then every 6 hours until negative reading obtained.

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).
