Clinical Investigation Study to Evaluate the Consistency and Reproducibility of Two Consecutive Mosquito Feeding Assays

In the direct feeding assay a cup with 60 unfed, sterile insectary-reared Anopheles gambiae mosquitoes will be allowed to feed on a participant's calf or arm for 15 minutes.

Participants will receive one dose of primaquine 26.3 mg tablet on Day 2 after completion of the direct feeding assay.

Participants will receive artemether (80 mg) and lumefantrine (480 mg) combination tablets twice a day for 3 days, starting after completion of the direct feeding assay on Day 2.
