There are about 470 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 purpose of the study is to evaluate the pharmacokinetics (PK), safety, tolerability, and acceptability of a single dose of pretomanid, added to an optimized background tuberculosis treatment regimen (OBR), in children with rifampicin-resistant tuberculosis (RR-TB) with or without human immunodeficiency virus (HIV).
A double blinded, placebo-controlled, multicenter trial to evaluate effectiveness of azithromycin prophylaxis on mortality in advanced HIV.
Tuberculosis (TB) remains a major global public health problem, particularly in low- and middle-income countries (LMICs) in Africa, Asia, and Eastern Europe. Approximately 10 million people fall sick with TB, causing up to 2 million deaths, worldwide per year. Considerable progress was made in TB control from 1990-2015, motivating the World Health Organization (WHO) to launch an ambitious EndTB strategy. However, the effect of the ongoing Coronavirus Disease 2019 (Covid-19) pandemic has been devastating and the last two years have seen the first year-on-year increases (of 5.6%) in TB mortality since 2005 . In order to regain lost ground, and re-establish progress towards elimination of TB, innovation is needed in all aspects of TB control, including development of shorter treatment regimens for drug susceptible (DS) and multi-drug resistant / rifampicin resistant (MDR/RR) forms of the disease. This protocol seeks to conduct the TB clinical trial combining the 8-methoxyfluroquinolone and optimised dose of rifamycing to address two questions. The first is to confirm the non-inferiority of a four-month optimised dose rifamycin and moxifloxacin-based regimen amongst African TB patient populations with high rates of co-incident HIV. Secondly, we seek to establish that the rifamycin of choice in potent 4-month anti-TB treatments could be rifampicin as this will be more rapidly up-scalable for public health impact.
This trial will assess the long-term health and socioeconomic impact of interventions targeting low-density malaria infection (LMI) among children in Tanzania
Heavy bleeding after childbirth, known as a postpartum haemorrhage (PPH), causes about 70,000 maternal deaths every year. Tranexamic acid (TXA) is a lifesaving treatment for women with PPH. The I'M WOMAN trial is a research study to see whether giving TXA just before childbirth will stop women developing PPH. The trial will assess the effects of intramuscular (IM) and intravenous (IV) tranexamic acid on PPH, side effects and other important maternal health outcomes.
To compare the efficacy and safety of emodepside to that of albendazole (Zentel®) in participants aged 12-60, inclusive, infected with hookworm.
The goal of the study is to operationalize and test the preliminary impact of providing regular customer feedback from adolescent girls and young women (AGYW) to drug shopkeepers on the distribution of contraceptives and HIV self-testing to AGYW over 18 months.
Introduction An increase in cardiovascular disease (CVD) among people living with HIV infection is linked to platelet and immune activation, a phenomenon unabolished by antiretroviral (ARV) drugs alone. In small studies, aspirin (acetylsalicylic acid [ASA]) has been shown to control immune activation, increase CD4+ count, halt HIV disease progression and reduce HIV viral load (HVL). The investigators present a protocol for a larger suspended randomised placebo controlled trial on the effect of an addition of ASA to ARV drugs on HIV disease progression. Methods and analysis A single-centre phase IIA double-blind, parallel-group randomised controlled trial intended to recruit 454 consenting ARV drug-naïve, HIV-infected adults initiating ART. Participants were randomised in blocks of 10 in a 1:1 ratio to receive, in addition to ARV drugs, 75 mg ASA or placebo for 6 months. The primary outcome is the proportion of participants attaining HVL of <50 copies/mL by 8, 12 and 24 weeks. Secondary outcomes include proportions of participants with HVL of >1000 copies/mL at week 24, attaining a >30% rise of CD4 count from baseline value at week 12, experiencing adverse events, with normal levels of biomarkers of platelet and immune activation at weeks 12 and 24 and rates of morbidity and all-cause mortality. Intention-to-treat analysis will be done for all study outcomes.
The purpose of this study is to learn more about the challenges with breast cancer diagnosis in Tanzania and the support available to improve this process.
Vitamin B12 is a cofactor for 2 enzymes that have essential functions in pregnancy, both for maternal health and for fetal development. However, there is currently limited data regarding the metabolic fate and optimal dose of supplemental vitamin B12 and its relationship to vitamin B12 status in pregnancy. This is a single-blinded, stratified, dose-ranging trial of maternal vitamin B12 supplementation during pregnancy that will be conducted at the Ifakara Health Institute Bagamoyo Clinical Trial Unit in Tanzania. The investigators will enroll 40 pregnant women (gestational age 25-28 weeks) and 10 non-pregnant women (comparison group). Participants will be blinded to dosing (2.6, 10, and 50 µg) and supplementation will be given for four weeks. With this trial, the investigators aim to enhance our understanding of vitamin B12 bioavailability during pregnancy in people with sufficient and insufficient baseline B12 status, identify priority dose regimens of vitamin B12 in pregnancy for investigation in later phase clinical trials to be conducted in populations where vitamin B12 insufficiency or deficiency is common, and identify biomarkers of vitamin B12 intake appropriate for pregnancy.
