There are about 36 clinical studies being (or have been) conducted in Madagascar. 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.
The goal of this phase 1b, multicenter, randomized, placebo-controlled, observer-blinded, dose-escalation study is to assess the safety, tolerability, and immunogenicity of a three-dose regimen, spaced four weeks apart, given intramuscularly in healthy adults (20-59 years old). Three different dose formulations of the study product with varying antigen contents will be investigated. A total of 120 eligible participants will be recruited in 3 sequential cohorts (A, B, and C) in Burkina Faso (N=60) and in Madagascar (N=60). Cohort A will receive the low-dose antigen formulation (10 µg) or placebo, Cohort B will receive the medium-dose antigen formulation (30 µg) or placebo, and Cohort C will receive the high-dose antigen formulation (100 µg) or placebo; all antigens with 5 μg adjuvant (GLA-SE). In each cohort, volunteers will be randomized in a blinded manner into one of two arms, candidate vaccine or placebo, by a 3:1 ratio. A subset of five out of 20 subjects in each cohort will be sampled by convenience to enable us to further characterize the immune response using the peripheral blood mononuclear cells (PBMC). The Primary Objective of the study is to evaluate the safety and tolerability of 3 different dose formulations (low dose, medium dose, and high dose) of SchistoShield® vaccine given intramuscularly on D0, D28 and D56 to healthy participants 2018 to 59 years of age in Burkina Faso and Madagascar.
1. To evaluate the performance of a lateral flow POC test, namely the Genital InFlammation Test (GIFT), for identifying women with inflammatory STIs and BV, who are at higher risk of HIV infection and reproductive complications; 2. To evaluate how the GIFT device can be integrated in a feasible, acceptable, and cost-effective way into routine care.
Tuberculosis (TB) whole genome sequencing (WGS) allows outbreak identification and disease transmission tracking. It is hypothesized that prospective WGS-guided epidemiological investigations improve case detection compared to current best practices by adapting contact tracing strategies to local transmission patterns. A cluster randomized controlled trial (cRCT) will be performed in high TB incidence villages of Haute Matsiatra region in Madagascar. Communities will be randomized in three separate TB control strategies comparing (1) standard of care, (2) the World Health Organization (WHO) recommended best practices and (3) a novel intervention involving TB WGS cluster-guided epidemiological investigations. The incremental value of TB WGS on case notifications and reduction of TB burden will be measured. Secondary studies will be nested within this cRCT will include: - A qualitative study which will increase the understanding of the factors facilitating and hindering implementation of WGS-based diagnostics within health systems. - A cost effectiveness analysis study which will measure the cost effectiveness of newly implemented laboratory methods. Field and genomic epidemiology data from this project will inform future work on the design of community-level TB elimination strategies in collaboration with Madagascar National TB program
Many people are affected by atopic dermatitis (AD) worldwide. However, clinical studies on AD in Sub-Saharan Africa are rare and there is a lack of knowledge about possible differences in pathogenesis between European and African AD. This study will collect clinical and laboratory data with the aim to compare clinical characteristics and immune responses in AD patients in Sub-Saharan Africa and Central Europe. Furthermore, relevant allergens as well as the nasal, skin and gut micro- and mycobiome will be investigated.
The overall objective of the study is to examine the effects of integrating early child development group sessions into the existing, at-scale, community health and nutrition programs administered by the government in Madagascar.
Enterobacteriaceae, more specifically Escherichia coli and Klebsiella pneumoniae, are the bacteria most often responsible for neonatal infections in low-income countries. Infections caused by multidrug-resistant Enterobacteriaceae: Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E), are more often associated with an unfavorable outcome of the infection. Enterobacteriaceae colonize the digestive tract which is the first step in developing a potential infection. Very few studies have been carried out at the community level. Colonization of the mother with ESBL-E is generally considered to be a major route of acquisition. The carrying of ESBL-E by other family members and other potential sources of transmission (food, objects and surfaces in contact with the newborn) have never been documented. In addition, with a view to offering an intervention adapted to the local context, the local cultural determinants which govern the interactions of the newborn with his environment are important to understand.
Plague is a deadly but highly treatable disease caused by the bacterium Y. pestis. Due to the historical development of Y. pestis as a bioweapon by several nation states, it is listed by the US as a potential bioweapon that could be used against US warfighters. Although this bacterium is ecologically established worldwide, it mostly affects impoverished people who live in rural low-resource areas of Madagascar. Plague is acquired directly from bites of infected fleas but, if left untreated, it can progress to the highly lethal pneumonic form that can result in human to human transmission. With the dangers of pneumonic plague in the context of both natural outbreak and as a bioweapon used against warfighter, the goal of this study is to investigate a diagnostic test that is able to rapidly and locally diagnose this disease in low-resource settings. This study aims to evaluate a US-developed new LFI (Lateral Flow Immunoassay) assay intended for capillary blood (finger-prick) to diagnose humans infected with Y. pestis. The investigators will rigorously validate with assay on human populations from active plague sites and correlate the results with the results of paired clinical samples used in standard medical workup using existing diagnostics tests.

As the survival of children with retinoblastoma in high income countries is higher than 95% including the bilateral forms this study hopes to improve the outcome in low income countries in Africa by improving early diagnosis and early implementation of this protocol of therapeutic recommendations for treatment.
This is the 4th LMB study by the French African Pediatric Oncology Group (GFAOP). The study hopes to be able to evaluate children earlier with stage I and II disease and to evaluate treatment response earlier so that the units can decide if a change in treatment is necessary, it is also hoped to provide an intensification of treatment for the stage IV disease.
