Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the gametocytocidal and transmission reducing activity of pyronaridine-artesunate (PA) and dihydroartemisinin-piperaquine (DP) with and without a single low dose of primaquine (PQ; 0.25mg/kg). Outcome measures will include infectivity at 2 and 7 days after treatment, the duration of infectivity in the artemisinin combination therapy (ACT) only arms, and the production and detectability of histidine rich protein II.

Outcome Assessors
This is a single blind randomised controlled trial. The treating physician and staff involved with assessing all laboratory outcomes of the study are blinded, but no placebo will be used. The study pharmacist will be unblinded and responsible for randomisation and treatment administration.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pyronaridine-artesunate (PA)

Subjects will receive pyronaridine-artesunate (PA) once daily for 3 days.

Group Type ACTIVE_COMPARATOR

Pyronaridine Tetraphosphate/Artesunate

Intervention Type DRUG

Adults: Tablets containing 180 mg pyronaridine-tetraphosphate/60mg artesunate (Pyramax, Shin Poong Pharmaceutical Co.), administered according to weight. Children: Granules containing 60 mg pyronaridine-tetraphosphate/20mg artesunate, administered according to weight.

PA with single low dose primaquine (PQ)
