There are about 751 clinical studies being (or have been) conducted in Kenya. 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 study will measure the incidence of moderate and severe adverse events (AEs) associated with PrePex procedures, including both procedural and post-procedure events, and all device-related incidents such as dislodgment. To assure complete ascertainment of AEs, study-specific forms will be used to collect standardized data from the circumcision visit and all follow-up visits. Follow-up will be more intensive for the first 50 cases, and will revert to routine practice (two follow-up visits) for the remaining 375 cases.
The purpose of this study is to demonstrate noninferiority (a new treatment is equivalent to standard treatment) in terms of the percentage of patients who have plasma human immunodeficiency virus-type 1 (HIV-1) ribonucleic acid (RNA) levels less than 400 copies per mL after 48 weeks of randomized treatment with tenofovir disoproxil fumarate/emtricitabine/rilpivirine (TDF/FTC/RPV) versus TDF/FTC/efavirenz (TDF/FTC/EFV).
The purpose of this study is to evaluate the safety, tolerability and immunogenicity of Sendai HIV vaccine SeV-G(NP) given intranasally and Ad35-GRIN administered intramuscularly in prime-boost regimens in HIV-uninfected, healthy adult volunteers.
The purpose of this study is to measure the independent and combined effects of interventions that improve sanitation, water quality, handwashing, and nutrition on child health and development in the first years of life.
The overarching aim of the Integra Initiative is to strengthen the evidence base on the impact of integrating family planning (FP), postnatal care (PNC) and HIV services in sub-Saharan Africa. Specifically, in the study the investigators aim to test the following hypotheses: the provision of integrated services, compared to separate services, will: 1. lead to increased uptake of a range of SRH services . 2. attract a greater number and diversity of clients. 3. lead to increased quality of a range of SRH services 4. lead to healthier sexual and reproductive behavior. 5. lead to reduced stigma at health facilities. 6. lead to the more efficient use of resources, with a lower unit cost of provision of key services. For the purposes of this study integration is defined as offering clients both HIV and postnatal care (PNC) or HIV and family planning (FP) services in the same visit. To better understand how services can be integrated in different countries this study focuses on two key models of integration in Kenya and Swaziland. - The first model focuses on integration of FP and HIV services (integrated FP model) and entails performing HIV testing, STI screening and management, cervical cancer screening, condom promotion within FP consultations, as well as active referral to antiretroviral (ART) units for HIV-positive clients. The FP model will be evaluated in Kenya only. - The second model focuses on integration of PNC and HIV services (integrated PNC model) and will be implemented in both Kenya and Swaziland. The model focuses on the provision of PNC services to mother and baby, FP services, repeat HIV testing for mother, HIV testing for infant and referral to HIV services for HIV positive mothers and infants, as well as referrals for clients requiring other additional services.
The underlying concept behind this feasibility trial is to achieve a reduction in indoor smoke from biomass fuels and minimize changes in cooking practices such that it prompts one of the two improved, ventilated cookstoves to be the selection of choice. Typical fuel sources used in developing countries include wood, dried dung, and agricultural waste. The investigators propose to reduce indoor air pollution by replacing the household traditional cookstove with an improved design that incorporates the following key elements: - Burner openings customized to the size and shape of the cooking vessels in the home. - Flue designed to draw air into the fire box under the cooking pots and pass it out through a chimney. - A chimney with adequate height to create a draft and vented to the exterior. - An exterior port that has bidirectional openings to prevent backflow of smoke. - An access port for the chimney that permits cleaning of soot. The investigators propose to use two types of improved cookstoves that meet these criteria. As part of piloting activities, the investigators will test several different types of commercially-available cookstoves with a chimney, and we may also want to test a locally-made improved cookstove. The investigators want to evaluate those designs by comparing their ability to reduce indoor air pollution, the reliability between cookstoves of the same type, the functioning over time, the logistics of import/build locally, preferences and cultural compatibility, and costs. The investigators will select two types of improved cookstoves to use in the feasibility trial. The study design will be a crossover intervention trial in which all patients will first have a run-in observational period of 4 months with the traditional cookstove prior to randomization. At baseline, the investigators will obtain sociodemographic information for each household, respiratory outcomes and other health data for the participating women, and cooking times and practices including the types of fuels used. All 40 patients at each site will receive the two types of improved cookstoves, one after the other: 20 will be randomized to receive the first type of cookstove with a chimney and the other 20 to first receive the second type of improved cookstove with a chimney. The patients will be followed for 4 months before the crossover. The investigators will assess cooking behavioral practices and compliance with cookstove use monthly, and respiratory and environmental measures at the mid-point of the 4 month period to minimize carry-over effects. At the end of second 4 month period, the investigators will switch the order of the improved cookstoves and follow all participants for another 4 months. The investigators will assess behavior, compliance, respiratory and environmental measures as above. The study is expected to require 12 months to complete.
The primary purpose of this pre-post evaluation is to test the impact on perinatal mortality (fresh stillbirths or early neonatal deaths) among births > 1500g of training birth attendants at health facilities in the Helping Babies Breathe (HBB) and Essential Newborn Care (ENC) curricula. These facilities are located within clusters in the Global Network for Women's and Children's Health Research sites in Belgaum and Nagpur, India, and Eldoret, Kenya.
Malaria in pregnancy (MiP) due to Plasmodium falciparum infection is a major cause of maternal morbidity and poor birth outcomes. Intermittent preventive treatment in pregnancy (IPTp) with Sulfadoxine pyrimethamine (SP), the administration of SP at predefined intervals in the second and third trimesters of pregnancy irrespective of the presence of malaria parasitemia, is currently recommended for HIV-negative women in all areas with stable moderate to high transmission of malaria. Due to increasing resistance to SP, it is no longer used as a treatment for symptomatic malaria, and the efficacy of IPTp-SP seems to be decreased. This study aims to look at a new drug, Dihydroartemisinin-Piperaquine (DP) for IPTp, as well as to explore the strategy of intermittent screening and treatment in pregnancy (ISTp) with DP. This strategy uses increased screening at time of focused antenatal care (FANC) with treatment of women who screen positive. The hypothesis is that the efficacy of both IPTp-DP and ISTp-DP will be associated with a reduction in malaria infection at delivery among HIV(-) women when compared to IPTp-SP, in an area with decreasing malaria transmission and high levels of SP resistance in Kenya.
Malaria transmission is falling in some parts of Africa as bed nets and anti-malarials become more widely available. However, transmission still persists and it appears that additional control measures are required. The leading malaria vaccine candidate in development is RTS,S which has efficacy against clinical malaria measured at 30-50% in the field. This partial protection might be enhanced by combination with other components. The other vaccination approach that has produced repeatable efficacy in humans is the use of viral vectors to induce T cell responses. Previous attempts with this vaccine approach have been effective in challenge studies in Oxford, but ineffective in the field, probably because of reduced immunogenicity. Recently, studies in Oxford, Kenya and the Gambia have shown higher levels of immunogenicity by using a chimpanzee adenovirus (ChAd63) followed by an attenuated vaccinia virus (modified vaccinia Ankara) to deliver the pre-erythrocytic antigen, multiple epitope string with thrombospondin- related adhesion protein (ME-TRAP). The increase in immunogenicity has lead to sterile protection in 3 out of 14 volunteers and partial protection in 5 out of 14 volunteers in challenge studies. The investigators propose a Phase 2b study of 120 healthy adult men in Kenya. The investigators will assess the efficacy and further evaluate the immunogenicity and safety profile of the vaccine regimen. The investigators also intend to assess the correlates of efficacy and natural immunity.
Kenya is one of the countries in sub-Saharan Africa that still experience high maternal mortality. For instance, in 2008/09 maternal mortality ratio was estimated to be 488/100,000 live births. Direct obstetric complications such as puerperal sepsis, postpartum hemorrhage, pre-eclampsia and eclampsia, obstructed labor and indirect causes including HIV, malaria and anemia in pregnancy are responsible for the majority of these cases. Just under 44% of births in Kenya are delivered under the supervision of a skilled birth attendant. The overall objective of this study is to determine the effect of provider type in the occurrence and management of serious childbirth related complications among postpartum women at the community level in Bungoma and Lugari Districts of Western Province, Kenya. The proposed study will employ a case control study design in which women with obstetric complication(s)will be cases and women without obstetric complications will be controls. Controls will be sampled concurrently with the cases. Each time a new case is diagnosed, a control is selected from the population at risk in the neighborhood at that point in time. The study population will consist of women aged 15-49 years with a delivery in the past 12 months. A woman who reports having experienced a birth-related complication will be recruited as a case while woman who reports having experienced no complication during child-birth will be recruited as a control.
