Active clinical trials for "Malaria, Falciparum"

The primary objectives of this study is to identify a safe, tolerable dose of pentoxifylline in children with cerebral malaria and to establish an acceptable pentoxifylline dosage regimen for use in multi center Phase II and Phase III studies.

The present proof-of-concept Phase IIa study aims to confirm, in patients, the observed activity of MMV390048 against P. falciparum in pre-clinical models and the human Induced Blood-Stage Malaria (IBSM) challenge model, and to determine the activity against P. vivax malaria in patients, both over 14 and 28 days. Additional aims are to characterise the safety of MMV390048 in patients. Patient safety will be monitored for up to 35 days post-dose including pharmacokinetic assessments. The study will investigate descending single doses of MMV390048 in response to results obtained in the first cohort/dose in each malaria sub-type. The results of this trial will identify active, well-tolerated doses for investigation in combination with a partner drug within a Phase IIb clinical trial.

This is a single-center open label study conducted in multiple sequential cohorts using Induced Blood Stage Malaria infection in healthy volunteers to characterize the effectiveness of KAE609 against sexual and asexual blood stage forms of Plasmodium falciparum. This study is divided in 2 parts (Part A and part B). A total of 8 healthy volunteers per cohort will be enrolled. Based on the results of Part A, Part B will be undertaken to evaluate the effect of KAE609 following pretreatment with Piperaquine on sexual stage/gametocytemia and its activity as an inhibitor of onward transmission to mosquito vectors using experimental mosquito feeding assays.

The purpose of this study is to determine if Azithromycin in combination with chloroquine is superior to chloroquine alone in eradicating P. falciparum asexual parasitemia in asymptomatic, semi-immune adults in Western Kenya.

The purpose of this study is to compare the effectiveness and safety of two Artemisinin Combination Therapies (ACTs) for the treatment of children with uncomplicated Plasmodium falciparum malaria

Primary Objective: To determine whether a single dose combination of OZ439 (Artefenomel)/FQ (Ferroquine) was an efficacious treatment for uncomplicated Plasmodium falciparum malaria in adults and children. Secondary Objectives: To evaluate the efficacy of OZ439/FQ: To determine the incidence of recrudescence and re-infection. To determine the time to relief of fever and parasite clearance. To evaluate the safety and tolerability of OZ439/FQ in adults and children. To characterize the pharmacokinetics of OZ439 in plasma, FQ and its active metabolite SSR97213 in blood. To determine the blood/plasma ratio for FQ and SSR97213 in some participants at limited time points in selected sites.

The RTS,S/AS01 malaria vaccine is being introduced sub-nationally in phased pilot introductions through the EPI programmes in Malawi Ghana and Kenya. Vaccine introduction is by the respective MoH in selected areas randomly assigned to receive the vaccine at the beginning of the pilots. In the context of this programmatic activity, the Malaria Vaccine Pilot Evaluation (MVPE) registered here as observational evaluations during early vaccine introduction, include a series of 3 household surveys, and sentinel hospital and community mortality surveillance, building on routine systems. These observational evaluations will measure: The programmatic feasibility of delivering a 4 dose schedule; Safety in routine use, with focus on cerebral malaria and meningitis; The impact of the malaria vaccine in routine use on severe malaria and all-cause mortality

The purpose of this study is to determine the safety and efficacy of sulfadoxine-pyrimethamine (SP) versus artemether-lumefantrine (Coartem) when administered to HIV+ and HIV- patients with uncomplicated P. falciparum malaria. Patients will be randomised to one of the 2 treatment and followed up (until day 14 actively) for 45 days.

The primary objective is to confirm the hypothesis that azithromycin (optimal dose once daily for three days) plus chloroquine is non-inferior to sulfadoxine-pyrimethamine plus chloroquine for the treatment of uncomplicated, symptomatic malaria due to P. falciparum.

This is an individually randomized, controlled, single blind four arm clinical trial of malaria chemoprevention strategies Arm 1: Intermittent preventive treatment with dihydroartemisinin-piperaquine (IPT-DP). Arm 2: Intermittent preventive treatment with sulfadoxine-pyrimethamine (SP) plus chloroquine (CQ) (IPT-SPCQ). Arm 3: Intermittent preventive treatment with sulfadoxine-pyrimethamine (SP) plus amodiaquine (AQ) (IPT-SPAQ).Arm 4: Control - students will receive standard of care (no preventive treatment). Outcomes include P. falciparum infection and parasite density, anemia, cognitive function and educational testing, as well as infection prevalence and disease incidence in young children sleeping student's households to assess the impact on transmission.
