About this trial
This is a single-center, open-label, randomized, four-period, six-sequence study with a planned enrollment of 24 healthy participants. The study consists of a screening period, a dosing period (Cycles 1, 2, 3, and 4), and a follow-up period. Screening must occur within 14 days prior to the first dose of study drug. Enrolled participants will be randomly assigned to one of 6 dosing sequences in the ratio of 1:1:1:1:1:1 to complete Cycles 1-3 dosing to evaluate the effect of different types of food on the PK of HMPL-760, and then to receive rabeprazole and HMPL-760 in Cycle 4 to assess the effect of PPI on the PK of HMPL-760 (see dosing sequence table for details).
