There are about 465 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.
The goal of this observational study was to evaluate the safety and acceptability of the ShangRing device for male circumcision among men in Shinyanga, Tanzania. The main question aims to answer both provider acceptability (practicality of device use and placement and removal times) and client acceptability (comfort during placement and removal, experience while wearing the ring, and penile appearance after healing). Participants voluntarily underwent male circumcision using the ShangRing device and before being discharged, were interviewed about their experience. Participants were also interviewed at device removal day (day 7), during a follow-up phone call (day 10), a sample were selected to participate in in-depth interviews (day28), and finally all men were asked to return for a follow-up visit (day 49).
This trial aims to characterise the pharmacokinetic (PK) profile and estimate drug exposure of a single oral dose of piperaquine (PQP) in a dispersible granule formulation compared to the PQP hard tablet formulation in the fasted state (Part 1), to advise the selection of dose when the PQP granule formulation is administered in a fed state in healthy adult participants. Part 2 will assess the effect on different types of meal composition on the PK of a single dose of PQP granule formulation in healthy adult participants.
The goal of this ancillary study, part of the DYNAMIC project, is to reduce antibiotic prescription and improve the quality of care for children in primary care in Tanzania using a near real-time mentoring tool (called medAL-mentor), based on a monitoring and benchmarking dashboard and feedback by the monitoring team. The main question to be answered is: Can real-time mentoring, based on clinical decision support algorithm data, improve healthcare workers' compliance with guidelines - and therefore quality of care for paediatric outpatients? Health providers in participating health facilities will receive either the medAL-mentor tool and feedback from the monitoring team (intervention group), or standard mentoring (control group), so that the impact on antibiotic prescription and other quality of care indicators can be compared between the two arms.
Background: Malaria prevalence has declined globally following the scale-up of the interventions, including insecticide-treated bed-net, indoor residual spraying, and prompt diagnosis and treatment with artemisinin-based combination therapy (ACT). Despite the gained success in the control, malaria has remained a major public health problem, particularly affecting children aged < 5 years in sub-Saharan Africa. Most of the malaria transmissions occur during the rainy season, a relatively short period. Intervention using antimalarial chemotherapy in children during the transmission season has been shown to prevent malaria-related morbidity and mortality. The World Health Organization has recommended seasonal malaria chemoprevention (SMC) using Sulphadoxine-pyrimethamine (SP) plus amodiaquine (AQ) in children aged 3-59 months in areas with highly seasonal malaria transmission. However, SP-AQ resistance is widespread in Tanzania. Therefore, this study will assess the effectiveness of Dihydroartemisinin-piperaquine (DHA-PQ) as SMC for the control of malaria among children in Tanzania. Methods: Afebrile children aged 3-59 months from Nanyumbu and Masasi districts in the Mtwara region will be enrolled in an open cluster randomized clinical trial, administered monthly with a full course of DHA-PQ for three or four consecutive months during the high malaria transmission season of the three consecutive years. Three approaches of DHA-PQ SMC administration will be tested; a door-to-door approach using community health workers (CHWs), outreach visits using local health facilities clinicians/nurses, and village health posts using selected CHWs. Study participants will then be followed-up to evaluate the impact of the intervention on all-course of malaria morbidity and mortality; adverse events associated with the intervention; acceptability, adherence, coverage, and cost-effectiveness of the intervention; treatment-seeking behavior; and the risk of rebound after the withdrawal of the intervention. The primary outcome will be a prevalence of clinical malaria defined as the presence of fever (axillary temperature of 37.5 degrees Celsius) or a history of fever in the past 24 hours and the presence of P. falciparum asexual parasitemia at any density. Findings: The findings will be disseminated through community meetings, seminars, local and international conferences, and publication in international journals. Impact: The findings from this study will provide information on the effectiveness of DHA-PQ for seasonal prevention of malaria morbidity and mortality in children aged < 5 years in Tanzania.
This project was a facility-based program intervention for People Living with HIV (PLHIV) aged 18 years and above who attended a Care and Treatment Center (CTC) in Dar es Salaam, Tanzania. Clients received preventive, diagnostic, and treatment services for Hypertension (HTN) and Type Two Diabetes Mellitus (T2DM). The primary health outcomes were all-cause mortality, disease-specific morbidity, HTN, and T2DM control rates. Secondary outcomes included access to care, retention in care adherence, and quality of care. Results obtained can be used to strengthen Non-Communicable Diseases (NCDs) care delivery in HIV/AIDS care in CTC in Tanzania.
Onchocerciasis is a neglected tropical disease associated with epilepsy, particularly in areas of high Onchocerciasis volvulus transmission. Onchocerciasis-associated epilepsy is characterised by seizures that start between the ages of five to 18 years. The tropical disease can be controlled through community-directed treatment with ivermectin (CDTi). Mahenge, in Tanzania, had a high prevalence of onchocerciasis and epilepsy despite more than 20 years of annual CDTi. Hence, the Tanzanian Neglected Tropical Diseases Control Programme has switched from annual to bi-annually CDTi since 2019. After this switch, the CDTi coverage increased and was sustained in both ivermectin rounds in 2021, and the number of new epilepsy cases decreased. The latter were persons who did not take ivermectin the year they had the first seizures. Hence, all ivermectin-eligible children at risk of onchocerciasis should take ivermectin at least annually. Overall, increasing the frequency and coverage of the CDTi programme should be considered in onchocerciasis-endemic areas with a high prevalence of epilepsy.
Malaria remains a major infectious disease causing a heavy burden of mortality and morbidity in populations living in tropical and subtropical regions. Large, international research efforts have been invested into the development of anti-malaria vaccination strategies, however, currently there is only one malaria vaccine approved for use in the pediatric population, which provides a moderate and short-lived protection. Therefore, there is a need to develop a malaria vaccine that will be essential to further strengthen malaria control measures in future. A Phase Ia trial with the same IMP (SumayaVac-1 vaccine developed using a full-length recombinant MSP-1 administered along with the adjuvant GLA-SE) in Caucasians in Heidelberg, Germany, proved to be well tolerated and safe. However, a Phase Ib clinical trial on healthy participants residing in a malaria endemic country would be essential to evaluate the safety and reactogenicity in the target population. The project aims to investigate the safety, reactogenicity, immunogenicity of the candidate malaria vaccine, SumayaVac-1 (SUM-101) in 40 healthy participants (men and women) of African origin in Bagamoyo, Tanzania.
The long-term objective of the parent study is "to reduce the effects of OPCa through secondary prevention (i.e., early detection, diagnosis and treatment referral)." Consistent with this, this supplement will test HPV-related interventions tailored for Sexual Minority Men (SMM). Acceptability, feasibility and preliminary effectiveness of a smart-phone delivered Oropharyngeal Cancer (OPCA) self-assessment tool will be assessed. Given that homosexuality is stigmatized and criminalized in Tanzania, and that cell phone use is the key way SMM communicate in Tanzania, a self-assessment screening cell phone intervention holds particular promise for SMM in Tanzania but warrants separate evaluation.
To compare the efficacy and safety of emodepside to that of albendazole (Zentel®) in participants aged 12-60, inclusive, infected with hookworm.
This study will work in Tanzania to develop and pilot test a simulation and experiential learning intervention for labor and delivery providers, in order to address HIV stigma during childbirth. The primary endpoint will be patient-rated changes in respectful maternity care, comparing women who deliver in the pre-intervention time period and women who deliver in the post-intervention period.
