There are about 472 clinical studies being (or have been) conducted in Tanzania. 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.
DAR-901 booster vaccine or placebo will be administered to adolescents in Tanzania primed with BCG to determine if immunization reduces the risk of TB infection
Home delivery of antiretroviral therapy (ART) by community health workers (CHWs) has the potential to reduce key barriers to ART care retention. The aim of this study is to determine whether CHW-led home delivery of ART for patients who are stable on ART combined with facility-based care for those not stable on ART is non-inferior to the standard of care (facility-based care for all ART patients) in achieving and maintaining virological suppression. The primary endpoint of this trial is the proportion of ART patients (regardless of whether they were clinically stable on ART at enrollment) who are in viral failure at the end of the study period. The non-inferiority design applies only to this primary endpoint. The margin of non-inferiority was set at a Risk Ratio (comparing intervention to control) of 1.45. This is a cluster-randomized controlled trial set in Dar es Salaam. The unit of randomization is a healthcare facility with its surrounding neighborhoods (the 'catchment area'). We matched all 48 healthcare facilities offering ART services and having affiliated public-sector CHWs in Dar es Salaam into pairs (stratified by district) based on having a similar number of patients currently on ART. In each pair, one cluster was randomized to the intervention and one to the control arm. The intervention consists of home visits by CHWs to provide counseling and deliver ART to patients who are stable on ART, while the control is the standard of care (facility-based ART care and CHW home visits at least every three months without ART home delivery). In addition, within each study arm, half of the healthcare facilities were randomized to enhanced CHW-led nutrition counseling and half to standard counseling.
The purpose of this study is to determine whether motivational text messages and/or travel vouchers are effective in increasing cervical cancer screening rates in urban and rural regions of Northern Tanzania.
The Malezi ne Kilimo Bora ("Good Parenting and Farming" in Kiswahili) Skilful Parenting and Agribusiness Child Abuse Prevention Study is a collaboration between the University of Oxford, University of Glasgow, and the Tanzania National Medical Research Institute (NIMR). It is pilot cluster randomised controlled trial (cRCT) of a community-based intervention implemented by Investing in Children and Our Societies (ICS), an international non-governmental organization (NGO) with extensive experience operating in rural Tanzania. The overall focus of the project is to evaluate ICS's agribusiness and skilful parenting programmes' impact on the prevention of child maltreatment and improvement of child and family psychosocial and economic wellbeing (n = 8 villages, n = 16 farmer groups, n = 240 families).
The present trial will evaluate safety and tolerability as well as the vaccine-induced humoral and cellular immune responses in healthy Tanzanian adults, adolescents, children, and infants who receive doses of 1.8x10^6, 9.0x10^5, 4.5x10^5 or 2.7x10^5 PfSPZ of PfSPZ Vaccine by direct venous inoculation (DVI),compared with control groups receiving normal saline (NS) placebo by DVI. In addition, as an exploratory objective, controlled human malaria infection (CHMI) will be used to assess efficacy in adults three weeks following immunization.
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.
This study will evaluate the safety and virologic effect of an experimental human monoclonal antibody (mAb), VRC-HIVMAB060-00-AB (VRC01), alone or in combination with antiretroviral therapy (ART), in adults during early acute HIV infection.
Drug efficacy testing is one of the most important tasks that is routinely undertaken by the National Malaria Control Program (NMCP) in Tanzania and has been recommended by the World health Organisation to monitor the efficacy of artemisinin based combination therapy (ACT) and possibly detect evolution/emergency of tolerance/resistance to these drugs. Currently, Artemether-lumefantrine (ALu) is the only ACT recommended by the Ministry of Health and Social Welfare and therefore testing of new ACTs such as dihydroartemisinin-piperaquine (DHA-PQ) is important because alternative drugs are urgently required. Meanwhile, NMCP is revising the guidelines for treatment of malaria in Tanzania and DHA-PQ has been earmarked as an alternative ACT to be used together with ALu. However, efficacy and safety data of DHA-PQ is missing since no studies have been done in Tanzania. Thus, a study is proposed to assess the efficacy and safety of DHA-PQ Vs ALu and provide important data which will enable the NMCP to make informed decisions; and possibly recommend DHA-PQ in the new Malaria treatment guidelines as the second line drug for the treatment of uncomplicated malaria in the country.
This study will evaluate the safety and efficacy of the human monoclonal antibody (mAb) VRC-HIVMAB060-00-AB (VRC01) in preventing HIV-1 infection in high-risk, HIV-uninfected women.
The use of long-lasting insecticide treated nets (LLINs) is shown to reduce malaria prevalence. The Tanzania Net Voucher Scheme has been an active component of bed net distribution to pregnant women in Tanzania since 2004. The transition from paper vouchers to electronic vouchers in this program has increased efficiency and the ability to track and distribute nets since 2007. Although the program has been successful, to date, electronic voucher redemption varies widely across the country and it has not been clearly established as to what barriers exist for women who receive electronic vouchers in the program. This cluster-randomized trial was designed to examine perceived barriers to electronic voucher redemption among pregnant women and to evaluate if educational and personalized text messages around electronic voucher redemption and bed net usage will increase electronic voucher redemption when directed at pregnant women who receive electronic vouchers in the currently existing program.
