There are about 140 clinical studies being (or have been) conducted in Mozambique. 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 purpose of this clinical trial is to evaluate a fixed-dose co-formulation (FDC) of ivermectin and albendazole for the treatment of all Soil Transmitted helminths (STH). The current strategy to control STH in endemic areas is mass administration of albendazole or mebendazole, mainly to pre-school and school-aged children. Although this treatment works well for some STH species, efficacy against Trichuris trichiura is poor and it is not effective Strongyloides stercoralis. Thus new drugs or drug combinations are an urgent priority to increase the effectiveness of control programmes. Furthermore, the World Health Organisation has recommended combination therapy of ivermectin with albendazole. The trial proposed, is an adaptive phase II/III trial where the phase II component will evaluate the safety of the FDC as a single dose or 3-day single dose regimen for the treatment of T. trichiura in paediatric population. After analysis of the safety results the phase III trial will be executed to evaluate the efficacy of the FDC as a single dose or 3-day single dose regimen compared to the standard single dose regimen of ALB (400 mg) for the treatment of T. trichiura, hookworm and S. stercoralis in paediatric and young adult population. The estimated total sample size for the adaptive design (phase II and III component) is 1223 participants. Of these, 126 will be enrolled in the phase II and 1097 in the phase III components respectively in an adaptive trial design.
The primary purpose of this study is to assess the preventive vaccine efficacy (VE), safety and tolerability of a heterologous prime/boost regimen utilizing Ad26.Mos4.HIV and aluminum-phosphate adjuvanted Clade C gp 140 for the prevention of Human Immuno Virus (HIV) infection in HIV-seronegative women residing in sub-Saharan Africa from confirmed HIV-1 infections diagnosed between the Month 7 and Month 24 visits.
Primary Objective: To determine whether a single dose combination of OZ439 (Artefenomel)/FQ (Ferroquine) was an efficacious treatment for uncomplicated Plasmodium falciparum malaria in adults and children. Secondary Objectives: - To evaluate the efficacy of OZ439/FQ: - To determine the incidence of recrudescence and re-infection. - To determine the time to relief of fever and parasite clearance. - To evaluate the safety and tolerability of OZ439/FQ in adults and children. - To characterize the pharmacokinetics of OZ439 in plasma, FQ and its active metabolite SSR97213 in blood. - To determine the blood/plasma ratio for FQ and SSR97213 in some participants at limited time points in selected sites.
This study investigates the prevention of early mortality in patients initiating antiretroviral therapy (ART) in sub-Saharan Africa where 79% of the co-infected cases of TB reside. Many published studies have shown a surprisingly high proportion of all patients initiated on ART dying within 6 months (8-26%) with increasing risk with decreasing CD4 T cell count. The majority (median 70%) occur in the first 3 months with the greatest proportion of deaths due to previously undiagnosed tuberculosis (TB). The investigators will enroll patients from 4 geographically diverse countries (Gabon, Mozambique, South Africa, and Uganda) in a randomized open label clinical trial targeting a population of people with high mortality risk; patients with CD4 T cell count < 50 cells/μl and body mass index (BMI) < 18 kg/m2. Severely immunocompromised patients with low BMI in the intervention arm will receive presumptive anti-TB 4-drug chemotherapy and subsequently initiate ART within 2 weeks compared to ART alone. The main objective is to measure and compare early mortality in the group presumptively treated for TB in addition to ART. Other sub-objectives are to determine the predictors of early mortality and the causes of death by autopsy (traditional and verbal), to determine if presumptive anti-TB treatment affects viral suppression with ART, and to assess incidence rates and characterize drug toxicity in patients dually treated. Because of the high rates of TB co-infection in sub-Saharan Africa in the HIV-infected, the investigators expect that patients presumptively treated for TB in addition to HIV will have a lower mortality rate than patients receiving ART only. This trial is expected to be of great public health benefit and generalisability.
The main purpose of this study is to compare the drug levels of artesunate and sulfadoxine-pyrimethamine found in pregnant women with malaria to those drug levels found in non-pregnant women from other studies. In addition the efficacy and safety of the study drugs will be determined for pregnant women and their babies.
