An Open Label Phase 1b Study to Characterise the Pharmacokinetic/Pharmacodynamic Relationship and Safety of MMV367 in Healthy Adult Participants Experimentally Infected With Blood Stage Plasmodium Falciparum
In Brief
A Phase 1 clinical trial evaluating MMV367 3mg, P. falciparum IBSM infection, and 5 other interventions for Infections and 11 related conditions. Completed, enrolled 12 participants across 2 sites.
Detailed Summary
This is an open-label, adaptive study using the P. falciparum induced blood stage malaria (IBSM) model to characterise the pharmacokinetic/pharmacodynamic (PK/PD) profile and safety of MMV367 (the IMP). Up to 18 participants will be enrolled in cohorts of up to 6 participants each. The study will proceed as follows for all participants: * Screening period of up to 28 days to recruit healthy adult participants. * Day 0: Intravenous inoculation with approximately 2,800 viable P. falciparum-infected red blood cells. * Days 1-3: Daily follow up via phone call or text message. * Days 4-7: Daily site visits for clinical evaluation and blood sampling to monitor malaria parasite numbers via quantitative polymerase chain reaction (qPCR). * Day 7 PM: Start of confinement within the clinical trial unit. * Day 8: Administration of a single oral dose of the IMP (MMV367). Different doses of MMV367 will be administered across and within cohorts in order to effectively characterise the PK/PD relationship. * Days 8-11: Regular clinical evaluation and blood sampling while confined to monitor malaria parasite numbers and measure MMV367 plasma concentration. * Day 11 AM: End of confinement within clinical trial unit. * Days 12-23: Outpatient follow-up for clinical evaluation and blood sampling. * Day 24: Initiation of compulsory definitive antimalarial treatment with Riamet® (artemether/lumefantrine) and/or other registered antimalarials if required. Treatment will be initiated earlier than Day 24 in the event of: * Insufficient parasite clearance following IMP dosing * Parasite regrowth following IMP dosing Characterising the pharmacokinetic/pharmacodynamic relationship of MMV367 * Participant discontinuation/withdrawal, * Investigator's discretion in the interest of participant safety. * Day 27: End of study visit for final clinical evaluation and to ensure complete clearance of malaria parasites.
