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 purpose of this study is to determine the efficacy of pyronaridine-artesunate and artemether-lumefantrine for the treatment of uncomplicated Plasmodium falciparum malaria in Kenyan children.
The purpose of this study is to determine whether one or two four-month regimens of tuberculosis treatment are as effective as a standard six-month regimen for treatment of pulmonary tuberculosis (TB). All three regimens are administered daily, seven days each week, with direct observation of each dose by a health-care worker at least five of the seven days of each week. The standard six-month regimen is two months of isoniazid, rifampin, ethambutol, and pyrazinamide followed by four months of isoniazid and rifampin. The first short regimen is a single substitution of rifapentine for rifampin: two months of isoniazid, rifapentine, ethambutol, and pyrazinamide, followed by two months of isoniazid and rifapentine. The second short regimen is a double substitution of rifapentine for rifampin and moxifloxacin for ethambutol: two months of isoniazid, rifapentine, moxifloxacin, and pyrazinamide, followed by two months of isoniazid, rifapentine, and moxifloxacin. Target enrollment is 2500 participants. Each study participant will remain in the study for 18 months in order to include at least 12 months of evaluation of whether the participant's TB recurs.
Available data suggest that low dose aspirin may be a safe, widely available and inexpensive intervention that may significantly reduce the risk of preterm birth. However, this possibility needs to be proven in a properly designed randomized controlled trial (RCT) with preterm birth as the primary outcome. Such a clinical trial in a racially, ethnically and geographically diverse population could best be accomplished by the established infrastructure of the Global Network for Women's and Children's Health Research (GN).
The purpose of the study is to develop and pilot-test a home-based intervention to facilitate sate HIV testing and disclosure within pregnant couples in order to increase use of prevention-of-mother-to-child-transmission (PMTCT) and family health services in Kenya.
The investigators are conducting a 3-arm randomized trial comparing the effects of unidirectional SMS (ie: "push" messaging to participant) vs. bidirectional SMS dialogue between participant and provider vs. control (no SMS) among HIV-infected Kenyan mothers in Kenyan PMTCT-ART for outcomes of ART adherence and retention in care.
The mainstay of control of soil-transmitted helminths (STH) is school-based deworming but recent modelling has highlights that in all but low very transmission settings, the treatment of school-aged children is unlikely to interrupt transmission, and that new treatment strategies are required. This study seeks to answer the question: is it possible to interrupt the transmission of STH and if so, what is the most cost-effective treatment strategy and delivery system to achieve this goal? In this study, two paired community cluster randomised trials in different settings in Kenya will evaluate the impact and cost-effectiveness of annual school-based deworming, annual community-based deworming, and biannual community-based deworming. The interventions are (i) annual mass anthelmintic treatment delivered either to pre-school and school-aged children, as part of a national school-based deworming programme, or to the entire community delivered by community health workers. The primary outcome measure is the prevalence of hookworm infection (the most common STH species), assessed by periodic cross-sectional, age-stratified parasitological surveys. Secondary outcomes include intensity of hookworm, prevalence and intensity of Ascaris lumbricoides, treatment coverage, and among a randomly selected sub-sample of participants who will be followed longitudinally, worm burden and proportion of eggs unfertilised. A nested process evaluation, using semi-structured interviews, focus group discussions and a stakeholder analysis will investigate the community acceptability, feasibility given the local and regional health system structures and processes, and scale-up of the interventions.
The enumeration of T lymphocytes positive for the CD4 antigen is used to determine the immune status of patients with, or suspected of developing, immune deficiencies such as AIDS. The BD FACS Presto™ is an investigational automated system for in vitro diagnostic use in performing the direct enumeration of CD4 absolute count, CD4 percentage of lymphocytes, and hemoglobin (Hb) concentration in human whole blood. This is a prospective study to determine the relative bias between the investigational BD FACS Presto system and the predicate BD FACS Calibur with BD Tritest system in their determination of absolute CD4, % CD4, and Hb concentrations.
In the past decade, massive scale-up of insecticide-treated nets (ITN) and indoor residual spraying (IRS), together with the introduction of artemisinin-combination treatments, have led to substantial reductions in malaria prevalence and incidence in African highlands. However, rising insecticide resistance and increased outdoor transmission have greatly hampered the effectiveness of ITN and IRS because the current indoor-based interventions do not target the outdoor-biting mosquitoes. Therefore, new supplemental interventions that can tackle outdoor transmission and pyrethroid insecticide resistance are urgently needed. The central objective of this study is to determine the efficacy and cost-effectiveness of EPA-approved long-lasting microbial larvicides in reducing malaria transmission and clinical malaria incidence in western Kenya highlands.
This is a research study in Kenya that will examine the outcomes of participants aged 10-15 and 16 and older; and provider acceptability of the Shang Ring technique for male circumcision that would simplify use. The study will be in two phases: Phase 1 will explore the no-flip technique that has been used in China but will be used for the first time in Africa. Phase 2 will be a randomized trial comparing use of tropical vs. injectable anesthesia.
The purpose of the two RCT registered here is to determine whether clinicians trained on the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST)-linked brief intervention (BI) through the NextGenU.org model of training are able to deliver effective brief intervention for risky level of alcohol use. It is one study part of a larger program of research. The investigators hypothesize that the NextGenU.org model of online training with mentor and peer activities is an effective way to train clinicians to deliver the ASSIST-linked brief intervention. The investigators hypothesize that eligible participants receiving the brief intervention will decrease their alcohol consumption and experienced improved health and social outcomes more than those receiving only screening results and written information (p<0.05). The investigators hypothesize the level of decrease in alcohol consumption will be similar to that of trials conducted in high-income countries (HIC).
