Filter by:This study will assess the efficacy of Pyramax administered for three-day, two-day or one day, in clearing a P. falciparum infection in asymptomatic carriers. .
This is an open label, randomized, controlled clinical trial. The primary aim of this project is to determine the safety and tolerability of NF135.C10 sporozoite immunization under chemoprophylaxis against homologous and heterologous challenge infection.
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: 1. The programmatic feasibility of delivering a 4 dose schedule; 2. Safety in routine use, with focus on cerebral malaria and meningitis; 3. The impact of the malaria vaccine in routine use on severe malaria and all-cause mortality
This study assesses the effectiveness of targeted active case detection among high-risk populations in Southern Lao Peoples Democratic Republic (PDR). The investigators hypothesize that active case detection using the next generation of HRP-2 rapid diagnostic tests (RDTs) can help bridge gaps in identification of high-risk asymptomatic individuals with low density parasitemia, allowing for targeting of this reservoir and thereby reducing transmission. The investigators hypothesize that active case detection (testing and treating positive cases) with these RDTs will lead to a reduction in P. falciparum transmission.
The general objective of this study is to assess the therapeutic efficacy and safety of artesunate + amodiaquine combined with a single low dose of primaquine (0.25 mg/kg) for the treatment of uncomplicated P. falciparum malaria patients in Zanzibar. The specific objectives are: - To determine the clinical and parasitological efficacy of artesunate + amodiaquine and primaquine in the treatment of uncomplicated Plasmodium falciparum infection. - To differentiate recurrent infections during follow-up, i.e. recrudescence from new infections, by polymerase chain reaction (PCR). - To evaluate the incidence of adverse events, particularly with regards to potential hematological adverse events of primaquine. - To determine the polymorphism of molecular markers associated with artesunate + amodiaquine tolerance/resistance. - To formulate recommendations, which will enable the Zanzibar Ministry of Health to make informed decisions about whether the current national antimalarial treatment guidelines should be updated or not. - To determine efficacy rate of the first line treatment compared to the first efficacy trial thirteen years ago.
The primary objective of the study was to determine the PCR-APCR up to day 42 in children <60 months of age, weighing ≥5kg with uncomplicated malaria, treated with either artesunate+ amodiaquine (ASAQ) or artemether-lumefantrine (AL; Coartem®). Secondary objectives included: clinical and laboratory assessment of drug tolerability and safety, evaluation of possible correlation between drug bioavailability and clinical outcome, comparison of efficacy data with the pre-implementation "ACO I" study, parasite and fever clearance, gametocyte carriage, and possible selection of mutations related to quinoline resistance.
The 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.
Investigators are conducting this study due to recent reports of many of existing malaria drugs becoming less effective for treatment of malaria. The drugs may not always kill all the parasites, therefore not all patients with malaria are being cured. The main objective of the study is to find out which malaria drugs and what drug combinations are still effective in Cambodia, an area of multi-drug resistance where 4-5 artemisinin-based combination therapies have shown inadequate response, below that established by the World Health Organization (WHO). New drug combinations (taking more than one drug for malaria at the same time), as long as well tolerated, can provide cure in patients that harbor parasites not responsive to standard first-line medications. Human genetic testing will be done to identify patients who may have suboptimal response to treatments and to study the differences in human gene expression to explain why some persons are at higher risk of complications during treatment. Markers of drug resistance to commonly used antimalarial drugs will also be evaluated and shared with national malaria program (CNM) to better guide future malaria treatment decisions in Cambodia.
The purpose of this study is to provide a new drug combination for a better treatment of P. falciparum for a faster parasite clearance and to counteract artemisinin resistance.
Primary Objective: To show the contribution of artefenomel (OZ439) to the clinical and parasiticidal effect of OZ439/Ferroquine (FQ) combination by analyzing exposure-response of OZ439 measured by Day 28 polymerase chain reaction (PCR)-corrected adequate clinical and parasitological response (ACPR) for the effect and the area under the curve (AUC) of OZ439 as pharmacokinetic (PK) predictor. Secondary Objectives: - To evaluate the exposure-response of OZ439 combined with FQ on crude Day 28 ACPR. - To evaluate the dose response of OZ439 combined with FQ on PCR-corrected and crude Day 28 ACPR. - To evaluate the dose-response of OZ439 combined with FQ on selected secondary endpoints. - To evaluate the safety and tolerability of different dosages of OZ439 in combination with FQ and FQ alone. - To characterize the PK of OZ439 in plasma, and of FQ and its active metabolite SSR97213 in blood.
