NCT ID: NCT05007821 Not yet recruiting - Tuberculosis Clinical Trials

Linezolid Dosing Strategies in Drug-Resistant TB

Start date: September 13, 2021
Phase: Phase 2
Study type: Interventional

The purpose of the study is to evaluate the efficacy (how well the medicines work) and tolerability (whether participants stop treatment because of side effects from a drug or treatment) of an anti-TB treatment regimen that compares two doses of linezolid (LZD), combined with bedaquiline (BDQ), delamanid (DLM), and clofazimine (CFZ). This study will also measure the level of these medicines in the participants' blood.

NCT ID: NCT04874688 Active, not recruiting - Stunting Clinical Trials

Child Health, Agriculture and Integrated Nutrition

Start date: April 26, 2021
Phase: N/A
Study type: Interventional

CHAIN is an open-label, individually randomized trial of improved infant and young child feeding (IYCF) versus "IYCF-plus" among 192 infants enrolled between 5-6 months of age in Shurugwi district, rural Zimbabwe. Interventions comprise sequential behaviour-change interventions delivered by village health workers together with food supplements. In the IYCF arm, infants will receive white maize and small-quantity lipid-based nutrient supplement (SQ-LNS) daily from 6 months of age. In the IYCF-plus arm, infants will receive orange pro-vitamin A-biofortified maize, and SQ-LNS, plus powdered sugar beans, moringa and whole egg powder. The primary outcome will be the proportion of infants in each trial arm reaching daily energy requirements at 9 months of age (visit window 9-11 months of age). Secondary outcomes are other nutrient intake, anthropometry and haemoglobin. Tertiary outcomes are laboratory measures of microbiome composition, environmental enteric dysfunction, inflammation, innate immune function, circulating choline and essential amino acids, and urinary metabolic profile. Two qualitative substudies will explore i) the feasibility and acceptability of the IYCF-plus intervention; and ii) the influence of migration on household food consumption and production.

NCT ID: NCT04860323 Recruiting - HIV Infection Clinical Trials

Analytical Treatment Interruption (ATI) to Assess the Immune System's Ability to Control HIV in Participants Who Became HIV-infected During the HVTN 703/HPTN 081 AMP Study

Start date: May 28, 2021
Phase: N/A
Study type: Interventional

The purpose of this study is to learn whether having the AMP Study antibody (called VRC01) in a person's body might help their immune system control HIV better, even without HIV medication called antiretroviral therapy or ART, if they get HIV. This study will evaluate the viral and immune system responses in an Analytical Treatment Interruption (ATI), in participants who received VRC01 or placebo and got HIV while enrolled in HVTN 703/HPTN 081 (NCT02568215). Participants in this study will stop taking their HIV medication. They will stay off HIV medication unless and until the HIV levels in their blood show that their immune system is unable to control the HIV or they meet other ART re-start criteria as noted in section "Detailed Description". While they are not taking HIV medication, their HIV levels will be tested frequently, and their health will be monitored closely. This is called an analytical treatment interruption, or an ATI. An ATI is an experimental procedure that is only used in carefully monitored research.

NCT ID: NCT04782739 Recruiting - HIV Infections Clinical Trials

Evaluation of the Impact of the COVID-19 Pandemic on Provision and Uptake of Services for the Prevention of Mother-to-child Transmission of HIV and Syphilis in Zimbabwe

Start date: March 15, 2021
Study type: Observational

The COVID-19 pandemic and response are likely to lead to severe unintended consequences for the prevention of mother-to-child transmission (PMTCT) of HIV and syphilis. Zimbabwe has made huge progress in coverage of antenatal testing of HIV and syphilis, which reached 98% and 91% in 2019, and is aiming for dual elimination. However, there is emerging evidence of disruption to health services due to COVID-19, similar to that seen in prior epidemics, which may reverse this progress. Mathematical modelling has estimated 3 and 6 month interruptions to ART supply would lead to 1.67 and 2.07 times more babies being born with HIV in SSA over the next year respectively. This study aims to provide real-world data to understand the effects of COVID-19 on the provision and uptake of PMTCT services. Our study has five objectives. Firstly, to conduct a retrospective analysis of national data routinely collected by healthcare facilities to explore changes before, during and after the pandemic in key indicators related to antenatal testing and treatment of HIV and syphilis, and management of HIV-exposed and infected infants. Secondly, data on neonates admitted to Sally Mugabe Central Hospital, already collected for the NeoTree study, will be analysed to explore the impact of COVID-19 on the number of HIV-exposed infants hospitalised, their clinical status at presentation and outcomes. Thirdly, qualitative studies with mothers and healthcare workers will explore barriers to optimal engagement with care and provision of PMTCT services respectively. Fourthly, quantitative results on testing and ART provision will be used to model the impact of disruptions on the rate of PMTCT of HIV enabling policy makers to plan for subsequent waves of COVID-19 and future epidemics. Finally, educational materials will be developed, piloted and disseminated during the project to provide information to pregnant women on safe access to PMTCT services.

NCT ID: NCT04781257 Recruiting - Tuberculosis Clinical Trials

Early Risk Assessment in Household Contacts (≥10 Years) of TB Patients by New Diagnostic Tests in 3 African Countries

Start date: March 2021
Study type: Observational

The ERASE - TB study will be conducted in order to fill a critical unmet need for tuberculosis control. Persons who are in contact with an infectious TB case may become infected themselves. Among those who are infected, most will stay healthy but some will develop TB themselves. These people would benefit from preventive treatment, which would also stop TB from being spread to other persons. The problem currently is that it is impossible to determine with certainty who would require preventive treatment, and who will remain healthy. Out of 100 persons exposed to an infectious TB patient, only 2 will go on to have TB according to a study in Vietnam, but there are no good tests available to identify those with a risk for TB disease. Treating 100 persons to prevent 2 cases of TB is not effective, so preventive treatment is not used in adults and adolescents in Tanzania, Mozambique and Zimbabwe, where this study will be conducted, but also in many other settings. The ERASE - TB project will evaluate a number of newly developed diagnostic tests, to see which of those will be able to predict TB in persons at risk, and therefore steer preventive treatment well. For this, the investigators will invite 2,100 household contacts (HHC) of infectious TB patients, who are at least 10 years old, into the study. Everyone will be examined initially, and again in regular intervals, for 1.5 to 2 years; and whenever the participants will present with symptoms that could indicate that they develop TB. At every visit, the investigators will perform an X-ray and take some blood and urine samples to perform new candidate tests. At the first/baseline visit, all household contacts without TB will undergo a spirometry to evaluate their pulmonary function. If someone is unwell, the investigators will also examine sputum for the presence of TB bacilli. In the end, the investigators will then be able to say who of the persons in the study developed TB, and who remained healthy. From all samples taken at different timepoints, the investigators will then determine which test found TB early, and clearly distinguished between persons developing TB, and persons who would remain healthy .

NCT ID: NCT04733157 Recruiting - Clinical trials for Postpartum Hemorrhage

NCT ID: NCT04480749 Active, not recruiting - Syphilis Clinical Trials

Syphilis Self-testing to Expand Test Uptake Among Men Who Have Sex With Men (SST)

Start date: October 14, 2020
Phase: Phase 4
Study type: Interventional

Syphilis infection is a major global health problem, leading to substantial morbidity among key populations in low- and middle-income countries (LMICs). Men who have sex with men (MSM) are disproportionately affected by syphilis worldwide. Rates of syphilis diagnoses have been increasing amongst MSM in many countries in the last decade. A growing evidence base supporting HIV self-testing shows that self-testing kits based on the same proposed clinical pathways are feasible and reliable. The proposed study will leverage this body of evidence and apply it to syphilis self-testing. This is a pilot study conducted in Zimbabwe. It aims to collect initial data on the feasability of implementing syphilis self-testing to establish if a large scale-RCT of this approach would be appropriate and, if so, to inform the design of this trial. The investigators will recruit 100 MSM in Harare to join the pilot program. Participants will be recruited through two methods: in-person at MSM community-based organizations that currently operate HIV self-testing programs and online through banner advertisements that advertise HIV self-testing. Study Arms: Arm 1: One arm of the pilot will receive a free syphilis self-test kit (Intervention Arm) Arm 2: One arm will receive standard free facility-based syphilis testing (Control Arm). Intervention: In the intervention arm the investigators will provide a treponemal rapid syphilis test kit to all participants in the intervention arm of the pilot, delivered through MSM community facilitators. This is similar to existing rapid treponemal test kits that are available at many clinical facilities. Kits will be accompanied by simplified pictorial instructions on finger prick blood sample collection. Among participants in the control group, they will receive a list of local clinics that can provide free syphilis testing. Data Collection: For individuals in the intervention am the investigators will aim to obtain confirmation of test uptake. This will be done using either photographic confirmation sent via encrypted message on a smartphone, SMS message of a unique code or sending a unique five-digit code along with their test result to the study coordinator. The investigators will conduct cross-sectional surveys at baseline and six months later to assess sexual risk behaviours, HIV and syphilis testing experiences, and self-testing experiences. In addition to the survey data tool the investigators will conduct in-depth interviews with a small number of participants to gain additional data about their experience of syphilis self-testing. The investigators will obtain information on linkage to care from routine clinic administrative records and by providing study participants with a unique code to be provided when attending at the facility. Analysis: The investigators will used mixed-methods to evaluate our pilot intervention including The investigators will examine the proportion of individuals who undertake a syphilis test in the interventional and control arms; among those who receive a test, the proportion of individuals who receive appropriate post-testing services. The investigators will also collect qualitative data on attitudes to syphilis self-testing and quantitative data on syphilis prevalence to inform a subsequent clinical trial.
