NCT04609098 ↗	Single Low Dose Tafenoquine to Reduce P. Falciparum Transmission in Mali (NECTAR2)	Completed	London School of Hygiene and Tropical Medicine	Phase 2	2020-10-29	The purpose of this study is to assess the gametocytocidal and transmission reducing activity of dihydroartemisinin-piperaquine (DP) with and without various low doses of tafenoquine (TQ; 1.66mg/kg, 0.83mg/kg, or 0.415mg/kg). Outcome measures will include infectivity to mosquitoes at 2 and 7 days after treatment, gametocyte density throughout follow-up, and safety measures including haemoglobin density.
NCT05081089 ↗	Gametocytocidal and Transmission-blocking Efficacy of PQ in Combination With AL and TQ in Combination With SPAQ in Mali	Not yet recruiting	London School of Hygiene and Tropical Medicine	Phase 2	2021-10-01	The purpose of this study is to compare the gametocytocidal and transmission reducing activity of artemether-lumefantrine (AL) with and without a single dose of 0.25mg/kg primaquine (PQ) and sulfadoxine-pyrimethamine with amodiaquine (SPAQ) with and without single dose of 1.66mg/kg tafenoquine (TQ). Outcome measures will include infectivity to mosquitoes at 2, 5 and 7 days after treatment, gametocyte density throughout follow-up, and safety measures including haemoglobin density and the frequency of adverse events.
NCT05203744 ↗	Escalating Monthly Doses of Tafenoquine in Healthy Volunteers	Not yet recruiting	Australian Defence Force Malaria and Infectious Disease Institute (ADF MIDI)	Phase 4	2022-02-10	In 2018, the U.S. Food and Drug Administration (FDA) and the Australian Therapeutic Goods Administration (TGA) approved tafenoquine for malaria prevention. The approved tafenoquine prophylactic regimen is 600 mg loading dose (200 mg daily for 3 days) prior to travel and a weekly 200 mg maintenance dose commencing 7 days after the last loading dose. This weekly tafenoquine regimen is more convenient with potentially improved compliance than daily doxycycline or atovaquone proguanil (Malarone), the other recommended prophylactic agents by the U.S. Centers for Disease Control and Prevention (CDC) for the prevention of malaria infections. Current assumptions are that a systemic minimum inhibitory concentration (MIC) of tafenoquine in plasma is 80 ng/mL in nonimmune individuals is required to prevent symptomatic breakthroughs of malaria infections. Because of tafenoquine's lengthy blood elimination half-life of 2-3 weeks, a monthly regimen of 600 mg and 800 mg of tafenoquine in individuals weighing 60 kg and 80 kg, respectively, have pharmacokinetic (PK) profiles (i.e., drug concentration versus time curves) of achieving MIC values of at least 80 ng/mL in the majority of healthy individuals. The aim of this study is to determine whether the safety and tolerability profiles in healthy participants taking monthly doses of 600 mg or 800 mg tafenoquine are comparable in the same participants taking weekly 200 mg tafenoquine. Study Hypothesis: The study hypothesis is that the frequency of tafenoquine-related safety (e.g. blood chemistries) and adverse events (AEs) in healthy participants who take a higher dose (600 mg and 800 mg) of tafenoquine monthly would be comparable to the frequency of treatment related safety and AEs in the same individuals who take weekly tafenoquine (200 mg).
