There are about 351 clinical studies being (or have been) conducted in Nigeria. 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 study is to assess the safety, tolerability and immunogenicity of different vaccination schedules of Ad26.ZEBOV and MVA-BN-Filo administered intramuscularly (IM) as 2-dose heterologous regimens in healthy and in HIV-infected adults.
The aim of this study is to compare the effectiveness and safety of Foley's catheter and misoprostol in cervical ripening.
The overall goal of this proposal is to conduct a partial double-blind randomized Phase III clinical trial for primary stroke prevention in children with sickle cell anemia (SCA) in sub-Saharan Africa.

The purpose of this study is to assess the safety and immunogenicity of the investigational ChAd3-EBO-Z vaccine administered to approximately 3 000 adults in Africa as a single IM dose Considering the risk of exposure to Ebola and the potential (based on animal data) for the investigational ChAd3-EBO-Z vaccine to afford at least partial protection, all subjects in the study will receive the investigational ChAd3-EBO-Z vaccine. The subjects in the Group EBO-Z will receive the vaccine at Day 0 of the study, whereas the subjects in the Group Placebo/ EBO-Z will receive a placebo at Day 0 (as a control) and will receive the investigational ChAd3-EBO-Z vaccine at Month 6, provided that no safety concerns are raised. In addition, vaccinating all subjects in the study with the investigational ChAd3 EBO Z vaccine will allow an increase of the safety database of the investigational vaccine. In case the geographic range of Ebola virus Zaire (EBOV) transmission expands to encompass any of the regions where this trial is conducted, earlier administration of the investigational ChAd3-EBO-Z vaccine to the subjects in the Group Placebo/ EBO-Z will be considered in that region.
A randomized controlled trial will be conducted to assess the effectiveness of conditional cash transfers (CCTs) at increasing retention in prevention of mother-to-child transmission (PMTCT) services specifically, in relation to pickup of ARV drugs for infected mothers, delivery in the hospital setting, and receipt of drugs for exposed infants. Administrative data will be extracted from the All Babies are Equal program and hospital records. At 8-10 weeks after delivery, an endline survey will also be conducted with each participant to provide a deeper understanding of the impact of the CCTs and to assess the reasons for retention in PMTCT services.
Mother-to-child transmission of HIV (MTCT) during pregnancy and breastfeeding is prevented with maternal antiretroviral drugs (ARV) and infant nevirapine post-exposure prophylaxis (PEP). However, the pharmacokinetics of certain ARVs is associated with marked inter-individual variability. This variability has been associated with single nucleotide polymorphisms (SNPs) in genes encoding metabolising enzymes, transporters and transcriptional regulators. Pregnancy is also associated with additional changes in pharmacokinetics. The resulting sub-therapeutic or supra-therapeutic drug exposures may have serious consequences for virological control, MTCT, emergence of drug resistance, and toxicity. Foetal and infant exposure to maternal ARV during pregnancy and breastfeeding is believed to play a role in the prevention of mother-to-child transmission of HIV (PMTCT). However, such exposures may also result in toxicity. For example, efavirenz is contraindicated in children less than 3 years old or 10kg but transferred to breastfed babies through breast milk. On the other hand, double exposure to nevirapine from breast milk and PEP may also predispose breastfed infants to nevirapine-associated toxicity. In the proposed study, the influence of selected SNPs in certain drug disposition genes on the pharmacokinetics of efavirenz and nevirapine during pregnancy and lactation, as well as the level of infant exposure to both drugs through breast milk, will be studied. Mathematical models will be developed to predict potential dose optimisation strategies during pregnancy, and to predict infant exposure to maternal drugs through breast milk.
This trials of cognitive stimulation therapy (CST) in Tanzania is part of the larger Identification and Intervention for Dementia in Elderly Africans (IDEA) study. The overall aim of the IDEA study is to set up and evaluate sustainable programmes to facilitate diagnosis of, and therapy for, people with dementia led by local communities in sub-Saharan Africa. The investigators seek to improve quality of life for people with dementia and their caregivers. Within this trial of CST, the investigators hypothesise that CST can significantly improve the quality of people with dementia and their carers living in Africa
This study aims to address the research question: Will continuous quality improvement, using a Break Through Series approach, increase uptake of PMTCT services and retention-in-care of HIV-infected pregnant women and mothers at six and 12 months postpartum? Continuous Quality Improvement (CQI) is a health systems intervention to assist programs to systematically improve services and health outcomes. The Break Through Series (BTS) is a specific CQI approach is a short-term (6- to 15-month) learning system that brings together teams from several hospitals or clinics ("collaboratives") to seek improvement in a focused topic area through a common process of data sharing and review Primary Objective To assess whether retention-in-care of HIV-infected women at six (6) months postpartum is higher at health facilities implementing CQI-BTS approaches than at health facilities not implementing CQI-BTS approaches. Secondary Objectives To assess whether implementation of CQI-BTS initiatives at health facilities increases: 1. Uptake of PMTCT services by HIV-infected pregnant women; 2. Retention-in-care of HIV-infected women at twelve (12) months postpartum; 3. Retention-in-care of HIV-exposed babies at six (6) and twelve (12) months of age; 4. Uptake of a pre-defined, minimum set of integrated RH/PMTCT services by HIV-infected women in health facilities.
