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.
More than 1.7 billion children worldwide experience violence in their upbringing. Prevalence rates are particularly high in Africa. Toxic stress associated with violence impacts the developing brain. This affects behavioral, social, and emotional functioning of children. The present project will test an intervention that simultaneously aims at reducing violence against children at home and at school. Within the project, (1) the feasibility, acceptability, and cost-effectiveness of the Intervention and (2) the initial effectiveness of reducing parental and teacher violence will be tested. To this end, a mixed-methods two-arm school-based pilot cluster-randomized controlled trial (CRCT) in Tanzania will be conducted. One unique and novel aspect of this project is to test a school-based intervention approach that targets both teachers and parents. A school-based approach including both teachers and parents has the following key advantages: (1) parents of different social, economic, and educational backgrounds can be motivated to participate and (2) using the existing infrastructure of schools reduces costs and will later improve the scalability of the program. The project is bringing together the global health, development economy, and psychological perspectives to promote our collaboration within the German global health community and with research and policy partners in Tanzania.
This is an independent evaluation of World VIsion's 7-year quasi-experimental intervention to improve nutrition, nutrition-related rights and gender equality for women, adolescent girls, and children under five years of age in rural Bangladesh, Kenya, and Tanzania. The evaluation will collect baseline, midline, and end-line data from intervention and comparison communities, schools, and health facilities. The evaluation objectives are to test if the intervention improved indicators for (i) child anthropometry, (ii) maternal and child dietary practices, (iii) women's empowerment, and (iv) equitable health service access for nutrition and sexual and reproductive needs. The evaluation analysis will take into account gender differences in the indicators.
This study aims to determine the effectiveness of community engagement using M-MAMA Champions on awareness of Obstetric Danger Signs, Birth Preparedness, and Complication Readiness among Pregnant Women in Bahi, Dodoma. This is a community-based, cluster randomized controlled trial (cRCT) study, whereby 120 first and second-trimester pregnant women will be randomized at a ratio of 1:1 to the intervention and control groups. The intervention of sensitizing pregnant women on Obstetric danger signs, birth preparedness, and complication readiness by the empowered M-MAMA Champions to the intervention arm clusters will be done for one month, a two-hour session will be delivered every two weeks, using participatory learning and action model for women groups to test the effectiveness of M-MAMA Champions in improving literacy level of obstetric danger signs, birth preparedness and complication readiness and its practice among pregnant women. The following is the hypothesis being tested Null Hypothesis; There is no difference in improvement of awareness of Obstetric Danger Signs, Birth Preparedness, and Complication Readiness among Pregnant Women when community engagement is done using M-MAMA Champions compared to routine approaches. Alternative hypothesis; Community engagement using M-MAMA Champions to improve awareness of Obstetric Danger Signs, Birth Preparedness, and Complication Readiness among Pregnant Women is more effective than routine approaches. During each 2-hour session, five (5) women will gather up and discuss the obstetric danger signs, birth preparedness, and complication readiness with the assistance of the M-MAMA Champion as a facilitator. An approved brochure on the concerned subject will be used for sensitization. Baseline data will be collected before and after the intervention. The control arm won't receive any intervention.
This study aims to improve HIV healthcare services for mothers living with HIV and their newborns in Tanzania and Mozambique. The main questions it aims to answer are: 1) does enhancing screening with maternal HIV viral load monitoring at delivery identify more mother-child pairs at high-risk for HIV vertical transmission? and 2) are high-risk infants linked to appropriate prevention and care? The study will expand access to HIV testing services to more rural settings using a hub-and-spoke referral system.
This study is a double-blind randomized controlled superiority trial aiming at providing evidence on the efficacy and safety of co-administered moxidectin and albendazole compared to albendazole monotherapy in school-aged children (SAC; aged 6-12 years) infected with whipworm (Trichuris trichiura) on Pemba Island, Tanzania. Additionally, evidence on the safety profile of moxidectin-albendazole combination in this age group will be substantiated using a placebo (and albendazole) only arm. To date, this has only been established in adolescents (aged 16-18 years), who might present different symptoms or symptom severity compared with SAC. As measure of efficacy of the treatment the cure rate (percentage of eggpositive subjects at baseline who become egg-negative after treatment) will be determined 14-21 days post-treatment.
This study is a single-blind randomized controlled dose-ranging trial aiming at providing evidence on the on the optimal dose of co-administered ivermectin and albendazole in terms of efficacy, safety and acceptability in preschool-aged children (PSAC; aged 2-5 years) infected with whipworm (Trichuris trichiura) on Pemba Island, Tanzania. Additionally, the pharmacokinetics of the newly developed ODTs and the standard ivermectin tablets (Stromectol®) will be compared in this age group. As measure of efficacy of the treatment the cure rate (percentage of egg-positive participants at baseline who become egg-negative after treatment) will be determined 14-21 days post-treatment.
Controlled human malaria infection (CHMI) has revolutionized the development of malaria vaccines. It involves the administration of either known numbers of sporozoites or infected erythrocytes to healthy human volunteers under a controlled environment. The use of highly sensitive molecular malaria diagnostic methods informs treatment decisions before symptom development and allows the characterization of parasite growth dynamics. Sporozoite CHMI has safely been used in six countries in Africa providing a platform to assess the efficacy of candidate malaria vaccines and study the natural immunity to malaria. Blood stage CHMI involves administration of known number of Artemether Lumefantrine sensitive infected erythrocytes in healthy volunteers, and it is a more sensitive model for modelling parasite growths and study the efficacy of blood-stage malaria vaccines. It has been safely used in Australia and Europe but not in Africa. Adaptation of this model by administration of combination of suboptimal and optimal antimalarial drugs lead to increased gametocytaemia, and infection rates in mosquitoes following standard membrane feeding assay. Such adaptation allows the model to be used to study parasite transmission from human to mosquitoes and evaluate transmission blocking malaria interventions. There is an urgent need to establish an in vivo model for early-stage clinical evaluation of transmission blocking interventions (TBI) in volunteers living in malaria endemic countries. This would allow rapid and cost-effective way to down-select transmission blocking candidate malaria vaccine and gametocidal antimalarial drugs before larger, more complex, and expensive field efficacy studies are conducted. A study done in naïve individual showed 100% success in establishing a malaria infection using 2800 P. falciparum infected RBCs, while a recent study (manuscript in development) has demonstrated success in establishing infection in Tanzanian semi-immune individuals with low malaria exposure using 1000 P. falciparum infected RBCs. We will use 1000 ALU-sensitive 3D7 P. falciparum infected RBCs to establish an in vivo transmission model for studying Transmission blocking interventions and assess the efficiency of two antimalarial drugs regimens (Piperaquine and doxycycline) to induce high levels of gametocytaemia and mosquito infection rates in healthy African adults. We will also investigate the determinants of successful transmission to mosquitoes including underlying immune responses to both asexual and sexual malaria antigens, asexual parasite dynamics and gametocyte burden, sex ratio of male and female gametocytes, and the relationship between gametocyte density and mosquito infection rate
This study is a multi-country and multi-site project to estimate the point-prevalence of high-risk (HR) HPV genotype infections among representative samples of girls and women aged 9-50 years, and among specific sub-populations to estimate the incidence of persistent HPV infection among sexually active young women. The data to fulfill the objectives will be collected through a series of Cross-Sectional Surveys (CSS) and Longitudinal Studies (LS) in all 8 countries 3 South Asian countries including Bangladesh, Pakistan, Nepal and 5 sub-Saharan African countries including Sierra Leone, Tanzania, Ghana, Zambia and DR Congo. Qualitative sub-studies (QS) will be conducted in selected countries and populations following the CSS to further understand and unpack risk factors for HPV infection as well as to explore how gender-related dynamics including perceptions of gender norms and stigma, influence HPV burden and/or create barriers that shape girls/women access to and uptake of HPV prevention, screening, and treatment services. Specific study protocols and corresponding ethical applications for the qualitative sub-studies will be developed separately.
Bacterial infections among young infants, including sepsis, meningitis, and pneumonia, continue to cause a substantial number of deaths globally. Zinc supplementation in combination with standard antibiotic therapy may represent a new intervention to reduce mortality and improve treatment outcomes for young infants with clinical severe infection. The Investigators will conduct a randomized, double-blind, placebo-controlled trial of zinc supplementation among young infants 0-59 days with severe clinical infection. The trial will enroll 3,250 Tanzanian infants hospitalized with clinical severe infection as defined by WHO Integrated Management of Childhood Illness (IMCI) guidelines. Enrolled infants will receive standard clinical management including antibiotics and will be randomized to receive either a 14-day course of twice-daily 5 mg elemental zinc (10 mg per day) or a matching placebo regimen.
The objective of the proposed research is to develop and pilot a locally-relevant, multicomponent intervention to streamline the triage process (e.g. patient assessment, stabilization, and disposition) for pediatric injury patients in Tanzania. This health systems intervention will work at the first level of medical contact (e.g., health center and district hospital), in order to facilitate timely disposition and referrals, and subsequently decrease time to definitive care. The proposed study has three aims: 1) With a mixed methods approach, describe the barriers to pediatric injury care at the first medical contact; 2) Iteratively develop the P-KIDs CARE intervention using a nominal group technique and conduct a pre-implementation assessment and refinement; 3) Pilot the P-KIDs CARE intervention and perform an implementation-focused formative evaluation. The proposed study focuses on pediatric injury patients and the family members and healthcare providers that care for them in Kilimanjaro, Tanzania. The investigators will recruit pediatric injury patients, family members, and healthcare providers from 2 health facilities in the Kilimanjaro Region.
