There are about 3545 clinical studies being (or have been) conducted in South Africa. 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 this study is to measure the efficacy and safety of baxdrostat/dapagliflozin in participants ≥ 18 years of age with CKD and HTN. This study consists of a screening, a 4-week dapagliflozin run-in period for participants naïve to SGLT2i at baseline; a 24-month double-blind period in which participants will receive either baxdrostat/dapagliflozin or dapagliflozin; and a 6-week open-label period in which all participants will discontinue baxdrostat/placebo and receive dapagliflozin alone. Site visits will take place at 2-, 4-, 8-, and 16- weeks following randomisation. Thereafter visits will occur approximately every 4 months, until the 24-month visit at which time baxdrostat/placebo will be discontinued. Participants will continue open-label dapagliflozin for another 6-weeks (approximately), where reassessment of GFR will occur for the primary efficacy endpoint. In the event of premature discontinuation of blinded study intervention, participants will continue in the study and receive open-label dapagliflozin monotherapy, unless the participant meets dapagliflozin specific discontinuation criteria, in which case all study interventions will be discontinued.
The goal of this hybrid (1a) Cluster Randomised Controlled Trial phase 3B trial is to evaluate the effectiveness and implementation of offering a choice of HIV Pre-Exposure Products (PrEP) through community-based sexual and reproductive health services, on PrEP uptake and retention, and population prevalence of sexually transmissible HIV amongst adolescents and young adults living in rural South Africa. Researchers will compare adding the choice of long-acting PrEP, i.e. two monthly injectable cabotegravir (CAB LA) or dapiravine vaginal ring and HIV post exposure prophylaxis packs to daily oral PrEP integrated with community-based SRH in the 20 intervention clusters with standard of care (SoC), daily oral PrEP integrated with community-based SRH in the 20 control clusters, on uptake and retention on PrEP. We hypothesise that offering a choice of long-acting or oral PrEP and PEP within the community-based delivery of SRH services will overcome the challenges and barriers to effective use of oral daily PrEP and lead to a population-level effect on uptake and retention on PrEP and thus the prevalence of sexually transmissible HIV amongst 15-30 year olds living in rural KwaZulu-Natal, South Africa.
The goal of this study is to determine the effect of the ENHANCE intervention in improving clinical outcomes and evaluating the effects of the intervention on implementation processes and outcomes. The specific questions it aims to answer are: 1. To test and estimate the effect of the intervention in people with MLTCs attending PHCs on: i. Detection of, and initiation of treatment for, additional chronic conditions ii. Treatment intensification and changes in medication iii. Control of chronic conditions iv. patient reported health-related quality of life and functioning v. health care utilisation and adherence vi. costs of health care 2. To use the RE-AIM framework to assess implementation processes and outcomes through measurements of reach, adoption, implementation, and maintenance. 3. To understand implementation processes and outcomes within the wider context of primary healthcare, provide explanations for the observed effects of the clinical findings and identify recommendations for wider implementation of the ENHANCE intervention. The participants in the control group will receive usual care at their primary health care facility, which includes the use of the Practical Approach to Care Kit (PACK) or Adult Primary Care (APC) clinical decision support tool. Participants in the intervention group will receive care for their multiple chronic condition by a clinician trained to use the ENHANCE clinical decision support tool (intervention tool), and receive two CHW visits in their home to provide treatment literacy and adherence support.
This study will look at how well CagriSema helps people with type 2 diabetes lower their blood sugar and body weight. CagriSema is a new investigational medicine. Doctors may not yet prescribe CagriSema. CagriSema will be compared to a medicine called tirzepatide that doctors may prescribe in some countries. Participants will get either CagriSema or tirzepatide. Which treatment participant get is decided by chance like flipping a coin. Participant will have an equal chance of receiving either drug. For each participant, the study will last for up to one and a half years.
It has been estimated that 1.7 billion people have tuberculosis (TB) infection; yet current tests are unable to predict which people are at highest risk of developing TB disease, which can be life-threatening. THWART-TB is a prospective longitudinal cohort study of health workers (HWs) in Cape Town, South Africa, where our preliminary data reveals HWs have a high annual TB infection risk (34%). This cohort, who will undergo frequent serial evaluation (every 3 months) with a combination of novel assays never previously evaluated together, presents a unique opportunity to evaluate immune responses at the time of initial infection and to characterize the dynamic profile of these immune responses over time in a high-risk population. The knowledge generated will improve our understanding of TB infection and help to identify which people exposed to TB may remain at risk, enabling us to better target preventive strategies.
This study will compare community-delivered, multi-month dispensing of tuberculosis preventive therapy (TPT) to standard-of-care clinic-based TPT delivery in a population of South African adults who are recommended to receive TB preventive therapy. We hypothesize that persons receiving multi-month dispensing of TPT in the community will have a higher rate of TPT completion at 3 months than persons receiving TPT via standard of care with monthly clinic-based refills.
Background A vast majority of adolescents do not meet guidelines for healthy physical activity, sedentary behaviour, and sleep, posing major risks for developing multiple non-communicable diseases. Unhealthy lifestyles seem more prevalent in urban than rural areas, with the neighbourhood environment as a mediating pathway linking urban living and poor health. How to develop and implement sustainable and effective interventions focused on adolescent health and wellbeing in urban vulnerable life situations is a key challenge and research gap. This paper describes the protocol of a Youth-centred Participatory Action (YoPA) project aiming to tailor, implement, and evaluate social and physical environmental interventions using an evidence-informed youth-centred co-creation approach, for structural improvement of the lifestyles of adolescents in urban vulnerable life situations. Methods In diverse urban environments in Denmark, the Netherlands, Nigeria, and South Africa, academic researchers will engage adolescents (12-19 years) growing up in vulnerable life situations and other key stakeholders (e.g., policy makers, urban planners, community leaders) in local co-creation communities. Together with academic researchers and local stakeholders, adolescents will take a leading role in mapping the local system for needs and opportunities; tailoring interventions to their local context; implementing and evaluating interventions during participatory meetings over the course of three years. YoPA applies a participatory mixed methods design guided by the newly developed SUPER-AIM framework assessing: (i) the local Systems, (ii) User perspectives, (iii) the Participatory co-creation process, (ii) Effects, iv) Reach, (vi) Adoption, (vii) Implementation, and (viii) Maintenance of interventions, in an integrated manner. Discussion YoPA aims to fill various research gaps, including the development of a practical protocol guiding the application of co-creation to tailor evidence-informed interventions to divers, multi-country contexts. Additionally, it focuses on advancing the research gap in physical activity and health within Sub-Saharan Africa and the involvement of adolescents in shaping their physical and social environments. Academic researchers envision that the YoPA co-creation approach will serve as a guide for participation of adolescents in vulnerable life situations in implementation of health promotion and urban planning in Europe, Africa and globally.
The overall goal is to determine whether an end-to-end decentralized delivery service for PrEP is more effective, safe, acceptable, and cost-effective than facility-based PrEP delivery.
This is a Phase III, multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the safety, tolerability and the effect of 2 mg Baxdrostat vs. placebo, administered QD orally, on the reduction of SBP, measured by average 24-hour ABPM in 212 participants with rHTN (defined as seated SBP ≥ 140 mmHg at Screening and mean ambulatory SBP ≥ 130 mmHg at baseline, despite a stable regimen of ≥ 3 antihypertensive agents, one of which is a diuretic).
This research study is being conducted to find out how easy, comfortable, and safe intravaginal rings are for women to use. The two rings used in this study do not dispense any medications, are the same size, but differ in their flexibility and hardness. This study will enroll approximately 100 HIV-negative persons, aged18-45 years, and assigned female sex at birth from sites in the United States, South Africa, and Zimbabwe. Participants will be randomly assigned to use (self-insert) Ring A for 4 weeks and then Ring B for 4 weeks or Ring B first followed by Ring A. There will be a 1-3-week rest period between using the two different rings. The study involves answering questions, undergoing pelvic examinations, and collecting blood and vaginal fluid samples over a total of 7 in-person visits and 2 telephone calls over approximately 9-11 weeks. In addition, both participants and approximately 30 of their sexual partners will be asked to take part in in-depth interviews to further assess acceptability, attitudes, and experiences with ring use to gauge interest in the future use of intravaginal rings as a HIV prevention option.
