Clinical Trials for Chloroquine Phosphate; Primaquine Phosphate

Trial ID Title Status Sponsor Phase Summary
NCT00158587 Eight Week Primaquine Regimen for the Treatment of Vivax Malaria Completed HealthNet TPO Phase 3 Plasmodium vivax represents a major health problem throughout the tropics. Outside Africa it accounts for over 50% of cases, affecting an estimated 70-80 million people per year. A substantial proportion of clinical cases are not caused by infective bites of Anopheles spp, but by activation of latent hypnozoites in the liver. These relapses may significantly impede development since each illness may result in 5-15 days of absence from work or school. Primaquine(PQ) is the only drug available that eliminates hypnozoites, though its use is beset by clinical problems; it may precipitate haemolytic anaemia in individuals deficient in the blood enzyme glucose 6 phosphate dehydrogenase (G6PD). Without affordable G6PD testing, primaquine use is precluded. Evidence suggests, however, that a course of 8 weekly doses may be a safe and effective alternative to the traditional 14 day course of the drug. The aim of the proposed study, therefore, is to test whether 8 weekly doses of primaquine is as effective as the 14 day course at preventing relapse malaria, without the risk of hemolysis in G6PD deficient individuals.

NCT01205178 G6PD (Glucose-6-phosphate Dehydrogenase) Study to Evaluate Hemolysis Potential of TFQ (Tafenoquine) Completed Medicines for Malaria Venture Phase 1 SB-252263 (Tafenoquine, TQ) is an 8-aminoquinoline (8-AQ) antimalarial drug being developed by GlaxoSmithKline (GSK), the U.S. Army Medical Research and Materiel Command (USAMRMC) and Medicines for Malaria Venture (MMV). TQ is currently being developed for the radical cure of acute P. vivax malaria in combination with standard doses of CQ, which is 1500 mg over 3 days. The current gold standard for radical cure of P. vivax malaria in many areas of the world is chloroquine (CQ) for clearance of the acute parasitemia immediately followed by primaquine (PQ) to clear the liver stages of the parasite and prevent disease relapse. The 8-AQ class of drugs, including PQ, is hemolytic in subjects with glucose-6-phosphate dehydrogenase (G6PD) deficiency. The current study will identify a dose of TQ within the target efficacious dose range that has a hemolytic effect similar to or less than PQ 15 mg OD x 14 days (i.e. ≤ 25-30% hemoglobin decline in WHO class III G6PD-deficient subjects).
