There are about 119 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.
Background: Half of the world's population is at risk of malaria. Malaria is a disease that affects many people in Mali and other parts of Africa. It is caused by germs spread by mosquito bites. Malaria may be mild. But it can also be serious or can lead to death if it is not diagnosed and treated promptly. Researchers want to learn more about the disease so they can develop new approaches to malaria control. Objective: To collect data on how mosquitoes spread malaria and how many people get malaria in the community by comparing different areas, seasons, and years. Eligibility: Residents of a certain area of Mali who are any age Design: Participants will be screened with a physical exam and medical history. All participants will have at least 1 visit. They will answer questions about their health and malaria. They may have a physical exam. They will have blood collected. Some participants will have 1 visit every month for 3 years. They will repeat the procedures above. These participants will have mosquitoes collected in their home monthly. They may be able to catch some of the mosquitoes alive or may need to use a spray to kill the mosquitoes. Participants in this part of the study can be up to 65 years old. Some participants will also have about 60 mosquitoes directly feed on their arm or leg for 15-20 minutes each month. These participants must be 5-65 years old.
Background: Malaria is caused by parasites carried by some mosquitos. When the mosquitos bite people, the parasites can infect them. One of these parasites is Plasmodium vivax (P. vivax). Some children have P. vivax in their blood. They did not have malaria symptoms, but some also had a blood problem called anemia. This can make people feel tired or weak. This could have been caused by P. vivax. Researchers want to know how P. vivax infects these children, and if it affects their health. Objective: To collect blood, stool, and urine monthly from children to look for infections with P. vivax, worms, and other parasites. Eligibility: Children between 6 months and 10 years old Design: For screening, the study will be explained to the participant s parents or guardians, who will provide consent. Participants will have a visit once a month for about 3 months, from November to January, and then for about 6 months from June to November 2018. Visits include: Questions about their health Medical history Physical exam Blood draw by pricking the finger tip Urine and stool collection. They may collect these at home and bring them back. If participants have P. vivax in their blood, them may need to come back to the clinic within 3 days. They will have blood taken from their arm using a needle. If participants feel ill during the study, they can go to the clinic for an exam and blood tests. If participants develop malaria while on the study, they will be treated. Participants samples will be stored for future research studies.
Recent advances in molecular diagnostics of tuberculosis, especially the GeneXpert Mycobacterium tuberculosis/Rifampicin test have reduced the time to diagnose Rifampicin Resistant Tuberculosis (RR-TB) but only rifampicin resistance is diagnosed, leading to presumptive diagnosis of resistance to isoniazid and maybe other drugs. Thus in low and middle income countries, most drug sensitivity testing relies on phenotypic drug resistance testing, which takes up to 4 months. In addition, currently, culture on monthly sputum samples is recommended by the World Health Organization for follow-up of Rifampicin Resistant Tuberculosis patients under treatment. Unfortunately, culture is often not locally available and samples need to be transported from field to culture laboratories. The associated transport delays lead to high rates of contamination and false negative culture, particularly in laboratories in low resource settings. Many gaps for the diagnosis and management of RR-TB patients still need to be addressed and the DIAMA project (DIAgnostics for Multidrug resistant tuberculosis in Africa) study aims to address some of them.
Out of the 13 identified serogroups of Neisseria meningitidis (Nm) the six serogroups (A, B, C, W, Y and X) are responsible for majority of infections. Presently available vaccines effectively protect against A, B, C, W and Y serogroups; but no vaccine that is protective against serogroup X is available yet. Serum Institute of India Private Limited (SIIPL) has developed a conjugate vaccine against serogroups A, C, Y, W and X (NmCV-5). The first-in-human Phase 1 study was among 60 healthy adults in USA did not show no any safety issues. This phase 2 study is designed to evaluate safety and immunogenicity of the non-adjuvanted and adjuvanted formulations of NmCV-5 in healthy children 12-16 months of age, in comparison with the licensed quadrivalent meningococcal conjugate vaccine (Menactra®). Both vaccines will be administered in two dose schedule 3 months apart. among vaccine-naïve healthy subjects in Mali. Safety will be assessed by collecting solicited reactions till day 7 post each dose whereas adverse events will be collected throughout the study. Each subject will be followed up for 84 days post each vaccine dose. The vaccine immunogenicity will measured using a rabbit complement serum bactericidal activity assay (rSBA).
This study aims to determine the most effective and tolerable dose at the shortest dosing regimen of the investigational drug KAF156 in combination with a solid dispersion formulation of lumefantrine (LUM-SDF) in adult/adolescent and pediatric patients with uncomplicated P. falciparum malaria. There is unmet medical need for anti-malarial treatment with new mechanism of action to reduce probability of developing resistance, and for duration shorter than 3 days of treatment and/or reduced pill burden.
A double-blind, individual randomised trial will be undertaken in 6000 children under the age of five years living in areas of Burkina Faso or Mali where the transmission of malaria is intense and highly seasonal to determine whether the malaria vaccine RTS,S/AS01 is (a) as effective as SMC with SP + AQ in preventing clinical malaria (b) provides additional, useful protection when given together with SMC. The primary trial end-point will be the incidence of clinical episodes of malaria detected by passive case detection. The costs of each intervention and its delivery will be determined and compared
Although the current World Health Organization (WHO) recommended management package for acute diarrhoea (ORS, zinc and feeding advice) has contributed to significant reductions in diarrhoea associated mortality, over half a million children continue to die annually as a result of acute diarrhoeal episodes. In addition, rates of mortality in young children in the 90 days following an episode of acute diarrhoea appear at least as high as mortality that occurs during the acute episode. The long-term benefits of antibiotic administration may result from direct antimicrobial effects on pathogens or from other incompletely understood mechanisms including improved nutrition, alterations in immune tolerance or improved enteric function. Optimizing antibiotic treatment of acute diarrhoea episodes in very young children with severe disease may offer the opportunity to significantly reduce diarrhoea associated deaths in the 90 days following presentation for acute diarrhoea and may also improve growth. The investigators propose to evaluate the efficacy of an antibiotic (azithromycin) delivered in a specific, targeted fashion to young children (< 2 years of age) at high risk of diarrhoea associated mortality in a multi-site randomized, double-blind, placebo-controlled trial. The study will evaluate the ability of the intervention to reduce mortality within 90 days of the acute diarrhoeal episode, and improve nutritional status over the same period.
The CADRE study is a multinational observational cohort of patients with sickle-cell disease (SCD) in five west and central sub-Saharan African countries. The aim of this project is to describe the incidence and assess the predictive factors of SCD-related micro- and macro-vascular complications in sub-Saharan Africa.
STUDY OBJECTIVE To confirm the incidence of in-hospital postoperative complications in adult surgical patients in Africa. STUDY DESIGN Seven day, African national multi-centre prospective observational cohort study of adult (≥18 years) patients undergoing surgery. Patients will be followed up for a maximum of 30 days. We will follow the original International Surgical Outcomes Study (ISOS) study design. The primary outcome is in-hospital postoperative complications in adult surgical patients in Africa. Secondary outcomes include in-hospital mortality and the relationship between postoperative complications and postoperative mortality. The intention is to present a representative sample of surgical outcomes across all African countries. This study will run between February and March 2016.
SMC LNS Mali is a interventional matched-pair clustered cohort carried out between August and November 2017 in 18 health areas in Kolokani Circle, Koulikoro region, Mali. The objective of this study is to determine whether the association SMC and LNS reduces the number of confirmed malaria cases among children 6-59 months during the monthly SMC distribution sessions.
