There are about 154 clinical studies being (or have been) conducted in Mali. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
In this randomized, double-blind, placebo-controlled trial, 222 healthy Malian children aged 6-10 years, residing in Bancoumana and surrounding villages, will be administered three doses of 9.0x10^5 Pf sporozoites (PfSPZ) of PfSPZ Vaccine (or placebo) at 1, 8, and 29-days using direct venous inoculation (DVI). The study is composed of a single cohort with two arms (categorized by placebo control/experimental groups) designed to assess the safety, immunogenicity and protective efficacy of PfSPZ Vaccine. All subjects will receive artemether-lumefantrine (AL) approximately 1- 2 weeks before the first and third doses of PfSPZ Vaccine or normal saline for clearance of Pf parasitemia. Vaccinated participants and non-immunized controls will be followed for safety and monitored for development of parasitemia through the natural malaria transmission season to estimate vaccine efficacy (VE).
Vaccine hesitancy is defined by the WHO's Strategic Advisory Group of Experts on Immunization as a 'delay in acceptance or refusal of vaccination despite availability of vaccination services'. This varies in form and intensity based on when and where it occurs and what vaccine is involved. Several prophylactic vaccines against COVID-19 are currently available. As the world is beginning the roll-out the first approved vaccines, little is known about people's potential acceptance of a COVID-19 vaccine in most of the African countries. ACHES (African COVID -19Vaccine Hesitancy) is an observational study aimed at measuring COVID-19 vaccine hesitancy in five west African countries and exploring causes behind the hesitancy with the main objective of informing guidelines for the proficient roll-out of the vaccines in the region.
The primary objective of the study is to demonstrate and quantify the protective efficacy of a single Spatial Repellent (SR) product, in reducing malaria infection in a human cohort. The study design will be a prospective cluster Randomized Control Trial (cRCT).
The new coronavirus known as SARS-Cov-2 (severe acute respiratory syndrome -coronavirus 2) was first reported in December 2019 and rapidly became a public health emergency. The COVID-19 pandemic is now affecting sensitive regions with fragile health care systems, such as South America and Africa. Caregivers, in the front line of Covid19 patient management, may accidentally become infected and a source of infection during the incubation phase or in case of asymptomatic infection. The objectives of this project are thus i) to assess SARS-Cov-2 spread over the hospital departments of Bamako by carrying out a systematic molecular screening of patients and caregivers, ii) to evaluate the feasibility of Point-Of-Care molecular assays in Mali and iii) to estimate the immunity acquired from SARS-Cov-2 among health workers through serological testing, allowing also the assessment of asymptomatic caregiver rate and absence of re-infection among the immunized caregivers. Finally, iv) variability of the virus over time and spread of different variants around the world will be studied by sequencing the viral genome.
This study is part of a series of projects to improve protection against meningitis. Previously, researchers have given nose drops containing N. lactamica to over 400 volunteers and shown that many of them become colonised with N. lactamica without causing any illness or disease. This has previously been shown to prevent people from becoming colonised with N. meningitidis which can cause meningitis. This study aims to give nose drops containing N. lactamica to healthy adults in Mali, to see if they become safely colonised. In the future the study team would like to find out how N.lactamica helps children resist N.meningitidis, and develop new vaccines that exploit that mechanism.
The purpose of this study is to assess the gametocytocidal and transmission reducing activity of dihydroartemisinin-piperaquine (DP) with and without various low doses of tafenoquine (TQ; 1.66mg/kg, 0.83mg/kg, or 0.415mg/kg). Outcome measures will include infectivity to mosquitoes at 2 and 7 days after treatment, gametocyte density throughout follow-up, and safety measures including haemoglobin density.
This is a randomized crossover study, where clinicians will be randomized to periods where they will use a rehydration calculator application with or without the Diarrheal Etiology Prediction (DEP) algorithm. The crossover will include a washout period to reduce carryover effect. The study will be conducted over a 9-week period. The Investigators will use a random number generator to randomize clinicians to DEP (use of the etiology calculator) or control arm (use of a previously-tested rehydration calculator) within site for the first 4 weeks. After the first 4 weeks, there will be 1-week washout period without decision support, after which each clinician will cross-over to the other arm for the next 4 weeks. The Investigators will enroll diarrhea-treating clinicians who treat children presenting with acute diarrhea at sites in Bangladesh and Mali. Utah investigators will only analyze de-identified data provided by our collaborators in Bangladesh and Mali.
This study aims to determine the efficacy, safety and tolerability of the investigational drug KAF156 in combination with a solid dispersion formulation of lumefantrine (LUM-SDF) in pediatric patients (6 months to < 18 years of age) with uncomplicated P. falciparum malaria. There is an unmet medical need for anti-malarial treatment with a new mechanism of action to reduce the probability of developing resistance, and for a duration shorter than 3 days of treatment and/or reduced pill burden.
Sanu Gundo ANRS 12392 is a non-randomized and non-comparative intervention trial in Mali. The main objective of the project is to study the feasibility of the community-based HIV care in the context of the artisanal gold mining zones and to evaluate its contribution to the linkage-to-care of PLWHIV with the health system and their retention in care, as well as its effect on their health status.
This is a phase IV, single-center, observer-blind, randomized, controlled vaccine trial in 2 to 10 years old healthy subjects. Each participant will receive a single intramuscular injection of one of the two vaccines either MPV ACYW® vaccine or Menactra ® vaccine according to the vaccine group assignment and will be followed up for one month for immunogenicity evaluation and for 6 months for safety evaluation. Statistical Hypothesis: H0: Seroconversion rate of test group is inferior to that of control group HA: Seroconversion rate of test group is non-inferior to that of control group Sample size calculation: the sample size was calculated based on non-inferiority test with alpha level of 0.025 and 80% power, assuming seroconversion rate in control group was 95% with non-inferiority margin at 10%. The sample size required for the study is 124 per arm. After adjusting for 5% drop-out, the final sample size required is 130 per arm.
