Efficacy and Safety Study of Tafenoquine (TQ) Co-administered With Dihydroartemisinin-piperaquine...
MalariaVivaxTafenoquine (TQ) is an 8-aminoquinoline anti-malarial drug which is in development as a single-dose treatment for the radical cure of P.vivax malaria when given with standard doses of chloroquine. Currently, the only available drug for radical cure is primaquine (PQ) which requires administration over 14 days, resulting in poor compliance. In Indonesia, chloroquine has been replaced by artemisinin-based combination therapy (i.e. ACTs) due to widespread chloroquine resistance. This study will evaluate the efficacy and safety of a single dose of tafenoquine when co-administered with an ACT (i.e. DHA-PQP). This single-center, double-blind, double-dummy, randomized study will test the superiority of DHA-PQP plus TQ against DHA-PQP alone in the prevention of P. vivax malaria relapse at 6 months. The study will be conducted in male Indonesian soldiers diagnosed with P.vivax malaria on return from deployment to a malarious region of Indonesia. A PQ plus DHA-PQP comparator arm is included to provide an informal comparison against the standard 14 day treatment for P.vivax malaria in Indonesia. Subjects who are glucose-6-phosphate dehydrogenase deficient (G6PD deficient) will be excluded due to the risk of acute hemolysis following dosing with 8-aminoquinolines drugs. Subjects who have a recurrence of P.vivax malaria during the study will be treated with an ACT plus PQ (0.5mg/kg for 14 days), in line with local treatment guidelines. At the end of the 6 month follow up period, any subject who has not relapsed will be given open label PQ (0.5mg/kg daily for 14 days) to minimize the likelihood of relapse after the study. Approximately 200 subjects will be screened to achieve 150 randomized subjects. The total duration of study for each subject will be 180-195 days. This study is being carried out to support registration of TQ in Indonesia and other countries where ACTs are first line therapy.
Safety, Tolerability and Pharmacokinetic Profile of Ascending Oral Doses of MMV390048, Part A
MalariaThis Phase I study will evaluate the safety, tolerability and pharmacokinetic properties of escalating single doses of reformulated MMV390048 when administered to healthy men and women of non-childbearing potential (WNCBP) under fasted conditions (Part A).

MalariaPharmacodynamic profiling will also be studied to characterize the effects of MMV390048 on P. falciparum clearance kinetics in healthy subjects using the Induced Blood Stage Malaria (IBSM) challenge model to determine the minimum inhibitory concentration of MMV390048 for P. falciparum (Part B).
Phase 2 Efficacy Study of Primaquine and Methylene Blue
MalariaThe purpose of this study is to determine the most efficacious transmission blocking drug regimen for seasonal malaria chemoprophylaxis in Mali. The primary outcome measure will be the proportion of mosquitoes infected pre and post-treatment, assessed through membrane feeding and measured by oocyst prevalence in mosquitoes dissected on day 7 post feed. Primary endpoint will be a within group comparison between the mean of the pretreatment infectivity (Day 0) and infectivity at 7 days post first dose.
Artemisinin-based Combination Therapy for Treatment of Plasmodium Falciparum Malaria in North Sumatera,...
MalariaFalciparumThis is a prospective, open label, randomised controlled trial to assess the safety and efficacy of dihydroartemisinin-piperaquine and artemether-lumefantrine in children and adults with uncomplicated Plasmodium falciparum malaria infection. Molecular markers for antimalarial resistance will also be assessed and the presence of molecular markers in the parasites will be associated with treatment outcomes.
Efficacy and Safety of ASAQ and PD for the Treatment of Uncomplicated Falciparum Malaria in Mainland...
Uncomplicated Falciparum MalariaThe World Health Organization recommends regular surveillance of antimalarial efficacy to monitor the performance of different drugs. The Tanzanian National Malaria Control Programme (NMCP) in collaboration with its partners have been implementing therapeutic efficacy studies (TES) to monitor the performance of different antimalarials in the country. Most of the studies conducted in recent years focused on artemether-lumefantrine which is the first line antimalarial for the treatment of uncomplicated malaria in Mainland Tanzania. However, data on the performance of other artemisinin based combination therapy (ACTs) is urgently needed to support timely review and changes of treatment guidelines in case of drug resistance to current regimen. This study was undertaken in the same NMCP framework to assess the efficacy and safety of alternative ACTs used or with potential use in Tanzania. The study assessed the efficacy and safety of artesunate-amodiaquine (ASAQ) and dihydroartemisinin-piperaquine (DP) for the treatment of uncomplicated malaria in Tanzania. The study was undertaken at two NMCP sentinel sites of Kibaha and Ujiji from July to December 2017.

Plasmodium Falciparum MalariaThe primary objective of the study was to determine PCR corrected cure-rates up to day 42 in children with uncomplicated malaria, treated with either Artesunate + Amodiaquine or Coartem®. Secondary objectives were to determine safety and possible selection of mutations related to the resistance of the tested drugs.

Gut and Azithromycin Mechanisms in Infants and Children II
MalariaChildhood mortality is decreasing worldwide. However, many sub-Saharan countries still have high children under 5 mortality rates. The MORDOR trial in Niger, Tanzania, and Malawi demonstrated a near 14% decrease in all-cause child mortality following biannual azithromycin in children 1-59 months. Current trials in Burkina aim to replicate these results from the MORDOR study with mass azithromycin treatment. The investigators conducted an individually randomized placebo-controlled trial in Burkina Faso called the Gut and Azithromycin Mechanisms in Infants and Neonates Trial (GAMIN: NCT03676751) to evaluate the effect of a single dose of azithromycin (20 mg/kg) on potential mediators of the effect of azithromycin on all-cause mortality and to evaluate changes in the gut microbiome longitudinally (results pending). Here, the investigators propose to conduct an expansion of the original GAMIN trial. In GAMIN II, the investigators will evaluate 450 additional 1-59 month old children longitudinally for 6 months with a focus on stool collection and malaria status. Objectives: 1. To determine the effect of a single dose of azithromycin for children aged 8 days-59 months on malaria. The investigators hypothesize that a single dose of azithromycin will result in a reduced malaria status within the treatment group compared to the placebo group after a 14 day period within children ages 8 days-59 months. The study will be conducted in Nouna Town in northwestern Burkina Faso.
