There are about 93 clinical studies being (or have been) conducted in Gambia. 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.
Diarrhea remains a leading cause of death among young children, with the majority of diarrhea deaths occurring in low- and middle-income countries. Childhood diarrhea caused by a type of bacteria called "Shigella" is responsible for an estimated 60,000 deaths each year and may cause particularly severe illness among children. Currently, there are several promising vaccines to prevent Shigella diarrhea in development, but key information is still needed to inform future vaccine studies. The purpose of this study, titled Enterics for Global Health (or the "EFGH"), is to determine the number and rate of new cases of Shigella diarrhea among children 6 to 35 months of age presenting to health facilities with diarrhea or dysentery. Over a two-year period, the EFGH study will enroll 1,400 children from each of the seven countries: Peru, Pakistan, Bangladesh, Mali, Malawi, Kenya, and The Gambia (9,800 children total).
This study will evaluate the efficacy and safety of a single dose of M5717 plus pyronaridine tetraphosphate in clearing current Plasmodium falciparum infection and protecting against recurrent infections in asymptomatic adults and adolescents. The study will also assess the duration of protection provided by different doses of M5717 plus pyronaridine and the additional contribution of M5717 to the duration of protection using external study data.
The study is designed as a Phase III, double-blind, multi-center, randomized, active-controlled study in which four groups of participants (n=554 per group) will receive either one of three different manufacturing lots of SII-YFV or STAMARIL® - a licensed and WHO pre-qualified YFV.
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
This study aims to describe the long-term adverse outcomes associated with PTB in children, to describe the evolution of these sequelae, and to determine the epidemiological risk factors associated with these sequelae. The investigators will conduct a prospective cohort study. Children who have completed treatment for PTB will be enrolled. The study visit will be performed in the study clinic, where clinical assessment, spirometry and radiography will be performed. The planned duration of the study is 36 months. Participant enrolment is estimated to begin in March 2022. The estimated date of the last participant enrolled is December 2022.
The trial aims to assess the impact of cheap, licenced and widely available investigational products on the natural history of SARS-CoV-2 infection in 2 groups of patients - those with mild or moderate pneumonia (Cohort 1) and those with severe pneumonia (Cohort 2), through randomisation to non-identical placebo or intervention arm.
This trial will evaluate the safety, pharmacokinetics, and efficacy of ivermectin in scabies infected children weighing 5 to less than 15kg. This will allow future efforts to expand the indication of ivermectin treatment to infants weighing 5 to less than 15kg to treat numerous NTDs, allowing this young age group equitable access to the numerous benefits of ivermectin therapy.
Investigator have previously shown that hepcidin is up-regulated even by low levels of inflammation and, according to our prior stable isotope studies, is predicted to block iron absorption. In this follow-up observational study, investigator aim to elucidate the potential drivers of this low-grade inflammation and to recalibrate the relationship between hepcidin and iron absorption using a more direct measure of absorption than the stable isotope method which measures the net of absorption and utilization. Investigator will study 120 ostensibly well children (6-24m) living in the rural region of West Kiang. Investigator will: 1. Use detailed clinical screening for possible origins of the low grade inflammation. 2. Assess iron absorption and its relationship to iron and anaemia status, inflammation, EPO, erythroferrone and hepcidin.
The Investigator have previously shown that hepcidin is up-regulated even by low levels of inflammation and, according to our prior stable isotope studies, is predicted to block iron absorption. In this follow-up observational study, the investigator aim to characterise the relationship between infections, acute inflammation, hepcidin and iron iron deficiency anaemia in rural African children. The Investigator will study 200 sick children (6-36 months of age) living in the rural region of West Kiang. The Investigator will: 1. Recruit 50 sick febrile children in each of 4 categories; Upper Respiratory tract infections, Lower respiratory tract infections (pneumonia), Urinary tract infections, gastroenteritis. 2. Assess iron absorption and its relationship to iron and anaemia status, inflammation, EPO, erythroferrone and hepcidin.
In the current study, three experimental approaches aiming at reducing malaria transmission will be tested. The study will cover two transmission season (2019 and 2020) and the interventions will vary by season. More specifically, in the 2019 transmission season (June-December) (Year 1), community case management of malaria (CCM) will be implemented in all eight villages as improved standard of care; in the 2020 transmission season (Year 2), the eight study villages will be divided into 4 study arms. CCM will continue in all villages; two villages will continue with CCM only (Arm 1, control); the three other pairs of villages will receive active fever screening and treatment (Arm 2); monthly mass screening and treatment (MSAT) (Arm 3); and mass drug administration (MDA) during the last 3 months of the dry season (April-June) (Arm 4). For MDA, the whole population (except for those not fulfilling the entry criteria) will be treated with a full course of dihydroartemisinin-piperaquine (DP) (320/40mg and 160/20mg piperaquine/ dihydroartemisinin per tablet) per manufacturer's guidelines (once daily for 3 days and according to body weight). The MDA treatment will be repeated 3 times at monthly intervals.
