Filter by:The purpose of this study is to measure the impact of maternal malaria on child growth in the two first years of life in relation to fetal growth. This study is following a birth cohort of children born to pregnant women enrolled in the study "Impact of malaria infection in pregnancy on fetal and newborn growth" (protocol OXTREC 14 08 and Mahidol 2009-003-01). In this cohort growth monitoring is conducted until 2 years of age using routine anthropometric measurements such as weight, length, arm and head circumference. A few additional tests will enhance the sensitivity of the study outcomes with minimal risk. These tests will include anthropometry, screening, nutrition questionnaire and neurodevelopmental assessment. This study was funded by Wellcome Trust core funding, grant ref. number Wellcome Trust Major Overseas Program Grant no. 220211 (2020-2025)
This will be a double-blinded randomized controlled phase III trial of 782 HIV uninfected pregnant women and the children born to them. HIV uninfected women at 12-20 weeks gestation will be randomized in equal proportions to one of two intermittent preventive treatment in pregnancy (IPTp) treatment arms: 1) monthly sulfadoxine-pyrimethamine (SP), or 2) monthly dihydroartemisinin-piperaquine (DP). Both interventions arms will have either SP or DP placebo to ensure adequate blinding is achieved in the study. Follow-up for the pregnant women will end approximately 6 weeks after giving birth. All children born to mothers enrolled in the study will be followed from birth until they reach 12 months of age.
Malaria remains an important cause of illness in young infants. Our clinical and epidemiological studies in Papua (Indonesia) have shown the magnitude of malaria morbidity in infants in the first 5 years of life, including recurrent episodes of malaria, anaemia, malnutrition and coinfection. Together these contribute significantly morbidity in early life, and almost certainly to the very high infant mortality rates in this region. However the body of knowledge around infant malaria outside of Africa, where both species P. vivax and P. falciparum are prevalent is considerable smaller. The impact of recurrent vivax malaria and severe anaemia on neurodevelopment and growth in young children is unknown in Papua. This study therefore aims to provide longitudinal data on the incidence of symptomatic and asymptomatic malaria (P. falciparum and P. vivax) and the associated risk of anaemia. It also provides an opportunity to assess incidence risk of non-malaria febrile illnesses and bacterial co-infections and the long term outcomes in terms of neurodevelopment and growth in a vulnerable age group. The study is a continuation from two already established cohort studies: "STOP MIP", which enrolled pregnant women and followed them until delivery and a "baby-cohort", which enrolled babies from mothers included in the cohort and followed them through their first year of life. Continuous follow up of those babies until they are 4 years old will increase our understanding of long term impact especially of vivax malaria. The cohort will be linked to a randomized controlled trial (RCT) and will offer cohort patients to be enrolled into the RCT when they are diagnosed with malaria (symptomatic), allowing to estimate treatment effectiveness.
Efficacy and safety of the artemisinin combination therapy (ACT) in uncomplicated falciparum malaria patients in Myanmar and artemisinin molecular markers analysis
The purpose of the study is to assess if the antimalarial drugs Dihydroartemisinine + Piperaquine (DP) are effective in preventing malaria infection for forest ranger
Plasmodium vivax can form dormant liver stages that reactivate weeks or months following an acute infection. Recurrent infections can be associated with a febrile illness, a cumulative risk of severe anaemia, and even mortality. In co-endemic areas the risk of recurrence after both P. vivax and P. falciparum infections can be over 50% within 3 months. The only drug we have to kill P. vivax hypnozoites is primaquine which is currently given as a 14 day regimen. In Papua a retrospective study found very low effectiveness for unsupervised treatment. If true this has profound effects on treatment policy, suggesting that greater efforts are needed to encourage adherence to treatment. We propose a cluster randomized, controlled, open label trial to assess the effectiveness of unsupervised versus supervised primaquine treatment in patients with uncomplicated malaria. Since the risk of recurrent P. vivax is high in patients with either P. vivax or P. falciparum, both infections will be included in the study. The study will be conducted in Mimika, in the southern part of Papua Province, Indonesia. Participants will be enrolled at village health posts and provided with schizontocidal treatment plus primaquine radical cure which will be either supervised or unsupervised depending on which cluster the clinic is in. Participants will be followed up for 6 months and assessed in regular intervals for the presence of patent and sub-patent malaria. The outcome of the study will contribute to an improved treatment scheme for uncomplicated malaria in this area.
Pharmacodynamic 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).
This 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).
This is a single center, randomized and controlled human study to optimize controlled human malaria infection (CHMI) administered by direct venous inoculation (DVI). 36 healthy adults aged between 18 and 45 years, will be randomized to one of five groups and will be inoculated with PfSPZ Challenge DVI. Participation duration is estimated to be 2 months, while the study duration is planned to be 4 months. The primary objective of this study is to assess the safety and reactogenicity of PfSPZ Challenge administered by DVI using 7G8 and NF54 P. falciparum strains.
This phase I trial of the replication-intact PfSPZ Challenge vaccine given under CQ cover will enroll 28 healthy volunteers to receive PfSPZ or placebo, as well as suppressive doses of chloroquine (CQ)on varying schedules. 10 weeks post 3rd immunization subjects will be subjected to controlled human malarial infection. The primary objective of this study is to evaluate the safety and tolerability of escalating doses of Sanaria PfSPZ Challenge administered by DVI on varying schedules to healthy malaria-naïve adults taking suppressive doses of CQ (PfSPZ-CVac).
