Filter by:This study is a multi-centre, open-label randomised trial to assess the efficacy, safety and tolerability of the Triple ACT artemether-lumefantrine+amodiaquine (AL+AQ) compared to the ACT artemether-lumefantrine (AL) in uncomplicated falciparum malaria in Cambodia and Vietnam. The estimated total sample size is 600 patients from 2 sites in Cambodia and 2 sites in Vietnam. There are 2 treatment arms Arm 1: Artemether-lumefantrine for 3 days Arm 2: Artemether-lumefantrine for 3 days plus Amodiaquine for 3 days. According to the World Health Organization guideline, all patients except children under 10 kilograms will also be treated with a single dose of primaquine as a gametocytocidal treatment.

KAE609 will be evaluated primarily for hepatic safety of single and multiple doses in sequential cohorts with increasing doses.This study aims to determine the maximum safe dose of the investigational drug KAE609 in malaria patients.
This clinical trial evaluates the advantage of prolonging the therapeutic life span of Artemether-lumefantrine from 3 days to 6 days, and addition of single low dose of Primaquine 0.25mg/kg. The study will have two arms, one that will receive standard treatment of uncomplicated malaria with Artemether-lumefantrine, and the other arm will receive the prolonged dose of 6 days together with single low dose primaquine. This approach is expected to provide strategies for malaria control in an era of imminent Plasmodium falciparum resistance.
The study is to be performed in public health facilities in Central and West Africa where Pyramax will be used as treatment of uncomplicated malaria episodes, including repeat episodes. The study is to assess the safety of Pyramax, particularly in patients with underlying liver function abnormalities, in patients who have co-morbid conditions, such as HIV, and also in very small children (<1 year of age).
This study follows a First-In-Human dose-escalation study of MMV390048 (5 to 120 mg MMV390048 powder-in-bottle formulation), a formulation bioavailability study to establish suitable tablet formulation, and a two-part dose-escalation (40 to 120 mg of MMV390048) / induced blood stage malaria (ISBM) challenge study with the new tablet formulation. After identification of the predicted efficacious MMV390048 plasma concentrations in the IBSM model, the current study will evaluate the chemoprotective efficacy of MMV390048 in a standardised and validated controlled human malaria infection (CHMI) model using direct venous inoculation (DVI) of aseptic, purified, cryopreserved, vialed P. falciparum sporozoites (PfSPZ Challenge). Three sequential cohorts of healthy men and women of non-childbearing potential (WONCBP) will be administered the investigational medicinal product (IMP, i.e. MMV390048) under different conditions. This may identify preventative regimens, to be further investigated in a Phase II program. In the first two cohorts, protective administration of the IMP will occur 1 and 7 days before DVI of PfSPZ challenge. The timing of IMP administration and dosage in the last cohort will be determined on the basis of emerging data from the preceding cohorts, but will not exceed 28 days prior to the challenge nor 120 mg MMV390048.
This is a randomized, three-arm, open-label, clinical trial of malaria chemoprevention in children with sickle-cell anemia (SCA) at a single site in Homa Bay, Kenya. The study will enroll 246 children under 10 years of age, randomize participants 1:1:1 to one of three malaria chemoprevention regimens, and follow participants monthly for 12 months in order to record clinical episodes of malaria or SCA-related morbidity. Analyses will compare the efficacy of each regimen to prevent malaria and SCA morbidity.
It has long been recognized that the positive effects of vaccination on childhood mortality cannot be solely attributed to a decline in the disease targeted by the vaccine. These so-called non-specific effects of vaccination have so far mostly been linked to mortality. However, it has been suggested that non-specific effects may also effect morbidity and nutritional status. This study aims to further explore the correlation between vaccination, susceptibility to infectious diseases (particularly malaria and bacterial infections), nutritional status and immunity. With this prospective cross sectional study among healthy individuals in rural west-Africa we aim to address several research questions at the same time. This study will assess the influence of (time-point of) vaccination on morbidity, mortality and immune status among healthy individuals in a rural sub-Saharan African setting. Secondly, to explore the prevalence of subclinical malaria, iron deficiency anemia, sickle cell anemia and thallasemia among a healthy rural sub-Saharan African population. And finally to assess normal hemocytometry values among a healthy rural sub-Saharan African population.
This study was designed to determine the most effective and tolerable dose at the shortest dosing regimen of the investigational drug KAF156 in combination with a solid dispersion formulation of lumefantrine (LUM-SDF) in adult/adolescent and pediatric patients with uncomplicated Plasmodium falciparum malaria. There is unmet medical need for anti-malarial treatment with new mechanism of action to reduce probability of developing resistance, and for duration shorter than 3 days of treatment and/or reduced pill burden.
A double-blind, individual randomised trial will be undertaken in 6000 children under the age of five years living in areas of Burkina Faso or Mali where the transmission of malaria is intense and highly seasonal to determine whether the malaria vaccine RTS,S/AS01 is (a) as effective as SMC with SP + AQ in preventing clinical malaria (b) provides additional, useful protection when given together with SMC. The primary trial end-point will be the incidence of clinical episodes of malaria detected by passive case detection.
In the underlying study, a genetically modified P. berghei parasite is used. P. berghei is one of the four Plasmodium species that causes malaria in rodents. The hypothesis is that immunization of humans with P. berghei will induce a cross-species immune response without the risk of a breakthrough infection. To further increase the potential for protective efficacy, the P. falciparum circumsporozoite (CS)- protein gene has been integrated in the P. berghei parasite, generating a genetically modified P. berghei parasite, abbreviated as Pb(PfCS@UIS4).
