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 find out how, why, and when Rift Valley Fever (RVF) spreads. Participants will be 250 adults and children, aged 1 year and older, from the Ijara District, Kenya. They will be given a questionnaire, undergo a medical examination that includes an eye exam, and have a 1-teaspoon sample of blood taken from a vein. Participation will take about 3 hours.
This study proposes a 4-armed factorial randomized clinical trial in Nairobi, Kenya to determine the effect of cognitive and behavioral interventions on HAART adherence.
The purpose of this study is to assess the efficacy and safety of SSG 30 days alone, PM 21 days alone and SSG and PM as a combination course of 17 days in the treatment of patients with VL.
The goals of this research are: 1) To test the efficacy of a self-care symptom management manual by examining whether people who use the manual find it to be useful; 2) To examine symptom and demographic data related to self-care behaviors, symptom control, medication adherence and enhanced quality of life. The University of California, San Francisco is the coordinating site for this multi-site international study.
This trial is currently evaluating one candidate malaria vaccine, FMP1/AS02A. This candidate malaria vaccine is being developed for the routine immunization of infants and children living in malaria-endemic areas. This vaccine would offer protection against malaria disease due to the parasite Plasmodium falciparum. Prior to the start of this study, FMP1/AS02A had been given to approximately 60 malaria-naïve adults and 40 adults and 90 children living in malaria-endemic regions. This study will investigate whether the candidate vaccine prevents malaria disease for 6 months post-vaccination. One half of the enrolled subjects will receive FMP1/AS02A and the other half rabies vaccine (RabAvert).
Tuberculosis is currently treated with a 6-month course regimen. During this time many patients might fail to adhere to treatment and default, increasing the risk of recurrent disease which might be multidrug resistant. A shorter duration of treatment is expected to provide improved patient compliance and at least equal or better clinical outcome. The aim of the trial is to evaluate the efficacy and safety of a gatifloxacin-containing regimen of four months duration for the treatment of pulmonary tuberculosis,
The candidate malaria vaccine RTS,S/AS02A developed by GSK Biologicals demonstrated 30% efficacy against clinical episodes of malaria and approximately 58% efficacy against severe malaria disease. As a potential improvement to RTS,S/AS02A, another candidate vaccine RTS,S/AS01B is being developed in parallel in collaboration with the Walter Reed Army Institute of Research (WRAIR). This study will be the first administration of the RTS,S/AS01B vaccine to the African adults to establish safety and immunogenicity in this population. Preliminary indication of vaccine efficacy with this adjuvant will be established by monitoring the time to the first infection with Plasmodium falciparum.
Following significant reduction in antiretroviral drug prices over the past two years, more HIV-1 infected African adults and children are gaining access to treatment. However, due to complex drug regimens that have to be taken continuously, suboptimal adherence is likely to be a formidable challenge. As programs providing antiretroviral drugs in Africa scale up, achievement of excellent adherence is a high priority as this will result in maximum benefits from the drugs and forestall development of resistant virus. A better understanding of predictors of pediatric HAART adherence in African children is essential in order to formulate feasible, culturally appropriate, strategies to monitor and enhance adherence. There is also urgent need to evaluate simple, inexpensive interventions that are widely applicable in the African setting. The medication diary has been used empirically among HIV infected adults and children in Western countries, mainly as a tool for monitoring and to a lesser extent improving HAART adherence. Literacy levels have risen significantly in most African regions over the past few years, and the diary can also be further modified using pictures to suit parents of different literacy levels. We propose to conduct a randomized control trial to determine the effect of medication diaries and counseling versus counseling alone on HAART-adherence in HIV-1 infected children and their parents/caregivers in Nairobi Kenya.
The University of Washington has received funding to conduct a proof-of-concept trial to assess the impact of suppression of genital herpes on HIV infectiousness. This study (the Partners in Prevention Study) will enroll HIV discordant heterosexual couples in which the HIV-infected partner is co-infected with herpes simplex virus type 2 (HSV-2) to test the efficacy of twice daily (bid) acyclovir (400 mg) given to the HIV-infected partner to prevent transmission to his/her HIV negative partner(s). This randomized, double-blind, placebo-controlled proof-of-concept trial will provide evidence for the efficacy of HSV-2 suppression with daily acyclovir on HIV transmission among HIV-discordant couples among whom the HIV-positive partner is also HSV-2 seropositive with CD4 >250. The researchers hypothesis is that, by decreasing the frequency and amount of genital HIV shedding, standard doses of daily acyclovir 400 mg bid will reduce the rate of HIV transmission by 50% in HIV-discordant couples among whom the HIV-infected partner is HSV-2 positive. Under the study protocol version 4.1.1, 3000 HIV-discordant heterosexual couples in which the HIV-positive partner is HSV-2 positive and has a CD4 count >250 will be recruited; participants will be followed for up to 2 years. A 4% per year HIV incidence in the placebo arm is assumed. The first study site began enrolling participants on 17 November 2005. As of September 2006, 14 sites in Eastern and Southern Africa had participated in recruiting the 2300 HIV-discordant couples enrolled to date.
The purpose of this study is to see if taking medication once a month can help to decrease the risk of vaginal infections. Additionally, researchers will study whether personal habits, such as douching, bathing, and sexual practices can influence the risk of vaginal infections. Vaginal infections may influence the risk of becoming infected with HIV-1 and other sexually transmitted diseases (STDs). Study participants will include 400 female prostitutes ages 16 and older, living in Mombasa. Study procedures will include sexual behavior questions, physical examinations including pelvic exams, testing of vaginal and cervical secretions for STDs, urine collection and blood samples. Participants will receive 2 different types of pills to treat vaginal infections (metronidazole or fluconazole) or placebo (contains no medication). Participants will be involved in study related procedures for 1 year and will return to the study clinic at one month intervals.
