Brief summary
The primary objective of this study is to determine the bioequivalence of the combination of pyronaridine and artesunate (180:60mg) to-be-marketed tablet to the clinical trial reference tablet administered as a single total dose of 720:240 mg in healthy adults. The secondary objective is to assess the safety of the two formulations.
Detailed description
This is a phase I, randomized, single dose, two-way cross-over study of two tablet formulations of the combination of pyronaridine and artesunate (180:60 mg). The study will include 42 healthy participants, comprising male and female adults. Participants will be randomized to receive either reference tablet formulation or to-be-marketed formulation first and then will be crossed over to receive the opposite Intervention. The study will consist of two single dose treatments of 720:240 mg tablets, separated by a washout period of 43 days. Participants will go to the clinic the evening before dosing (dosing days were Day 0 for period 1 and Day 43 for period 2) under fasting condition and remain in the hospital for 24 hours after receiving dosing. Participants will stay in the hospital for 24 hours after their arrival at the clinic. They will return to the clinic at Day 2, 3, 5, 7, 14, 21, 28, 35 and 42 on an ambulatory basis. At Day 43, the dosing for the second sequence will start and a similar schedule of visits will be followed. Each participant will be followed-up for an additional 42 days after the start of the second study period, until the final visit (Day 85). The total duration of participation is 85 days plus a maximum of 2 weeks screening period.
