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.
2-arm, double blind, placebo controlled, randomised trial, with 50 6-week-old infants per arm randomized to 98 days of daily iron (1.5mg/kg/day as ferrous sulphate) or placebo drops
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 randomized, double-blinded, placebo-controlled Phase 3 study is designed to evaluate the efficacy and safety of maternal immunization with RSVpreF against medically attended lower respiratory tract illness (MA-LRTI) in infants.
This is a phase 1/2, single-centre, double-blind, double-dummy, randomized, active-controlled, age de-escalation trial. Age de-escalation will be based on a review of the safety data from the preceding cohort (adults for toddlers and toddlers for infants) up to day 14 post study product administration by a data monitoring committee (DMC). All participants will receive either the MRV-MNP and a placebo (0.9% sodium chloride) SC injection (PLA-SC) or a placebo-MNP (PLA-MNP) and MRV by the SC route (MRV-SC). Only those study staff randomizing participants and preparing the study products for administration will be aware of the products administered. Those administering the study products, all other trial staff and the participants and parents will be blinded to treatment group. 45 adults (18 to 40-years-of-age) will be randomized in a 2:1 ratio. Thus, 30 adults will receive MRV-MNP and PLA-SC while 15 adults will receive MRV-SC and PLA-MNP. 120 toddlers (15 to 18 months-of-age) will be randomized in a 1:1 ratio. Thus, 60 toddlers will receive MRV-MNP and PLA-SC while the same number of toddlers will receive MRV-SC and PLA-MNP. 120 infants (9 to 10 months) will also be randomized in a 1:1 ratio. Thus, 60 infants will receive MRV-MNP and PLA-SC while the same number of infants will receive MRV-SC and PLA-MNP. Solicited local and systemic AE will be collected daily from all participants from the day of study product administration to day 13 post study product administration. Unsolicited AE and SAE will be collected from the day of study product administration to day 180 post study product administration. All participants will have laboratory investigations (hepatitis B, hepatitis C, hematology and biochemistry) conducted as part of screening. Adults will have safety laboratory investigations repeated on day seven and day 14 post study product administration. Toddlers and infants will have safety laboratory investigations repeated on day seven post study product administration. All participants will have measles- and rubella-specific SNA titers and measles- and rubella-specific IgG concentrations measured at baseline and day 42 and 180 post study product administration. Other Expanded Program on Immunization (EPI) vaccines due in toddler (oral poliovirus vaccine, diphtheria-tetanus-pertussis) and in infants (oral poliovirus vaccine, yellow fever vaccine and MenAfriVac® [due at 12 months]) will be given by the investigator team at the day 42 study visit (V4).
This study aims at investigating handwashing behavior during COVID-19 pandemic. It was hypothesized that social-cognitive and emotional predictors as well as COVID-19 morbidity and mortality rates within the country would be associated with handwashing behavior in the general population of adults in 14 countries.
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.
Clinical pneumonia is a leading cause of pediatric hospitalization. The etiology is generally bacterial or viral. Prompt and optimal treatment of pneumonia is critical to reduce mortality. However, adequate pneumonia management is hampered by: a) the lack of a diagnostic tool that can be used at point-of-care (POC) and promptly and accurately allow the diagnosis of bacterial disease and b) lack of a prognostic POC test to help triage children in need of intensive assistance. Antibiotic therapy is frequently overprescribed as a result of suspected bacterial infections resulting in development of antibiotic resistance. Conversely, in malaria-endemic areas, antibiotics may also be "underprescribed" and children with bacterial pneumonia sent home without antibiotic therapy, when the clinical pneumonia is mistakenly attributed to a co-existing malaria infection. The investigators previously identified combinations of protein with 96% sensitivity and 86% specificity for detecting bacterial disease in Mozambican children with clinical pneumonia. The investigators' prior work showed that it is possible to identify biosignatures for diagnosis and prognosis using few proteins. Recently, other authors also identified different accurate biosignatures (e.g., IP-10, TRAIL and CRP). In this study, the investigators propose to validate and improve upon previous biosignatures by testing prior combinations and seeking novel combinations of markers in 900 pediatric inpatients aged 2 months to 5 years with clinical pneumonia in The Gambia. The investigators will also use alternative case criteria and seek diagnostic and prognostic combination of markers. This study will be conducted in Basse, rural Gambia, in two hospitals associated with the Medical Research Council Unity The Gambia (MRCG). Approximately 900 pediatric patients with clinical pneumonia aged 2 months to 5 years of age will be enrolled. Patients will undergo standard of care test and will have blood proteins measured through Luminex®-based immunoassays. Results of this study may ultimately support future development of an accurate point-of-care test for bacterial disease to guide clinicians in choices of treatment and to assist in the prioritization of intensive care in resource-limited settings.
