Filter by:Lactating women requiring treatment for uncomplicated malaria will be identified and invited for sampling. The decision to treat them with first-line treatment will have been made by the clinician, not by a member of the study team. The study team will not make any adjustments to the prescribed treatment. Artemether-lumefantrine comprises six doses of medication, with the initial two doses given 8 hours apart on Day 1, and dosing 12-hourly on Day 2 and Day 3. Intensive pharmacokinetic sampling will be undertaken after Dose 5, as indicated in the schema under Section 5: plasma and breastmilk samples will be obtained pre-dose and at 2, 4, 6, 8 hours after dose. In addition, sparse sampling will be undertaken on either of these occasions; at pre-dose and between 1 to 6 hours after the first dose; a trough (pre-dose) sample after the Dose 3 or Dose 4 and lastly at 5, 7, and up to 14-days after the first dose. A heelprick sample will also be obtained from the breastfed infants at maternal trough (prior to maternal dose) and at a random timepoint (once per infant) over the 8-hour pharmacokinetic sampling visit to characterize concentrations of these drugs over an 8-hour dosing interval. In addition, a single heelprick sample will be obtained from the infant whenever the mother returns after treatment for the late sampling time points (5, 7, and 14 days post the first dose). Due to the long half-life of lumefantrine of approximately 6 days plasma sampling will be performed up to day 14 to characterise the terminal elimination of the drug. Concentrations of total plasma and breastmilk lumefantrine and desbutyl-lumefantrine will be determined.
USSPZV7 is a randomized, phase 1, double-blind, placebo-controlled trial of Sanaria® PfSPZ Vaccine administered on Days 1, 8 and 29 by direct venous inoculation (DVI) to assess safety, tolerability, immunogenicity, and vaccine efficacy (VE) against heterologous controlled human malaria infection (CHMI) with the 7G8 clone of Plasmodium falciparum (Pf) conducted at 3 or 12 weeks after the third immunization. The trial is designed to determine if individuals living in a non-malaria endemic area such as the United States (US) are protected against heterologous CHMI conducted at these time points.
This trial will assess the long-term health and socioeconomic impact of interventions targeting low-density malaria infection (LMI) among children in Tanzania
The purpose of this study is to compare the gametocytocidal and transmission reducing activity of artesunate-amodiaquine (ASAQ) and artemether-lumefantrine-amodiaquine (ALAQ) with and without a single dose of 0.25mg/kg primaquine (PQ). Outcome measures will include infectivity to mosquitoes at 2, 7 and 14 days after treatment, gametocyte density throughout follow-up, and safety measures including haemoglobin density and the frequency of adverse events.
This three-part, first-in-human, healthy volunteer study aims to assess the safety and tolerability of the test medicine as well as how it is taken up by the body when given as single and multiple doses. The effect of food on the test medicine will also be investigated. In Part 1, up to 40 volunteers will be split into up to 5 groups and will receive single oral doses of the test medicine or dummy medicine (placebo), at different dose levels. In Part 2, up to 8 volunteers will receive one oral dose of the test medicine in the fed state and one oral dose in the fasted state. In Part 3, up to 24 volunteers will be split into up to 3 groups and will receive single oral daily doses of the test medicine or placebo for 3 consecutive days. Volunteers' blood and urine will be taken throughout the study for analysis of the test medicine and for their safety. In Part 1 and Part 3, volunteers will be discharged from the clinical unit 4 days after the final dose of the test medicine and will return to the clinical unit on two occasions for safety assessments to be performed. In Part 2, volunteers will be discharged from the clinical unit 4 days after the final dose of the test medicine and will return to the clinical unit on a single occasion for safety assessments to be performed. Volunteers are expected to be involved in this study for approximately 6 weeks for all study parts, from screening to the final return visit.
This study will assess the coadministration of genetically attenuated Plasmodium falciparum ∆mei2 (GA2) sporozoites with adjuvants (BCG and YF-17D vaccination and imiquimod cream). Primary outcomes will be safety, tolerability and protective efficacy against CHMI.
This is an open label, single-site, first-in-human, dose-escalation Phase Ia study to assess safety and immunogenicity of the Plasmodium falciparum malaria vaccine candidate Pfs48/45 in Matrix-M adjuvant in healthy adults living in the UK
This is an open-label, single-centre Phase I P. falciparum blood-stage vaccine trial to assess the safety and immunogenicity and efficacy of the candidate malaria vaccines R78C and RH5.1 formulated in adjuvant Matrix-M
This is a Phase Ib multi-stage Plasmodium falciparum malaria vaccine study to assess the safety and immunogenicity of the blood-stage vaccine candidate RH5.2 virus-like particle (VLP) in Matrix-MTM and the pre-erythrocytic stage vaccine candidate R21 in Matrix-MTM, both alone and in combination, in adults and infants in the Gambia
Mozambique is among the ten countries with the highest burden of malaria worldwide, with an estimated 9.3 million cases in 2018, and constitutes a core target for the World Health Organization (WHO) and the Roll Back Malaria Partnership to End Malaria's country-led 'high burden to high impact' initiative. At the same time, the National Malaria Control Program (NMCP) of Mozambique seeks to accelerate elimination in the south, where transmission is lowest. NMCP is currently working with partners (Malaria Consortium, PMI, Global Fund) to set up a high-resolution surveillance system that can drive decision-making across all transmission strata through strengthening of routine data quality, data use and data to action packages. However, decisions become more complex as control reveals heterogeneity and better tools are required for a strategic use of information to drive impact. The overall objective of the study is to operationalize a functional malaria molecular surveillance (MMS) system that generates reliable and reproducible genomic data over time for programmatic decisions. The integration of genomic data into routine surveillance activities has the potential to increase the actionable intelligence for making programmatic decisions on the optimal mix of control and elimination measures in Mozambique by: 1. Informing drug and diagnostic choices through the monitoring of antimalarial drug resistance and diagnostic resistance (hrp2/3 deletions); 2. Targeting the reservoirs sustaining transmission through the use of transmission network models to quantify parasite importation, identify sources and characterize local transmission in near-elimination settings; 3. Improving stratification, monitoring and impact evaluations in different epidemiological and health system contexts through the use of measures of P. falciparum genetic diversity (routinely from positive cases) to supplement traditional surveillance, especially where it is sparse; 4. Using alternative, cost-effective, approaches targeting easy-access populations (e.g. pregnant women at antenatal care clinics) to monitor transmission and antimalarial/diagnostic resistance.
