The study will be divided into two parts. The first part will comprise up to seven fasted cohorts (8 to 10 volunteers in each) that will receive a single, ascending dose (SAD) of MMV390048 to assess its safety, tolerability and pharmacokinetic profile. The starting dose administered to the first cohort will be 5 mg. An additional cohort (cohort 8, re-using volunteers from one of the previous cohorts) will receive a single dose of MMV390048 in a fed state to evaluate the effect of food on the pharmacokinetics and tolerability of the compound.
