There are about 3551 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 pilot randomized controlled trial study aims to address the unmet need for feasible and efficacious strategies for reducing combustible cigarette (CC) use among people living with HIV/AIDS (PLWHA) in South Africa, which has the potential to significantly improve the health and long-term survival of PLWHA CC smokers. Using the proposed intervention, based on the Information-Motivation-Behavioral Skills (IMB), and a simultaneous embedded mixed methods approach, the investigators will evaluate a telehealth program targeting CC harm reduction, comparing E-cigarettes (EC) to nicotine replacement therapy (NRT) that is enhanced by integrating ecological momentary intervention (EMI) texting. As such, this proposal will significantly build research capacity in South Africa to conduct telehealth tobacco treatment interventions using innovative EMI approaches enhancing participants' engagement, as well as state-of-the art evaluation approaches.
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.
The goal of this pilot trial is to test the effectiveness of a newly developed multicomponent clinic-level intervention for improving retention in HIV care among people living with HIV in South Africa. The intervention was developed based on intensive study of clinics with high retention rates. The main questions this study aims to answer are: 1. Does the intervention improve retention in HIV care for people living with HIV (PLWH)? 2. Does the intervention improve viral load suppression for PLWH on antiretroviral therapy? The intervention, called "Connect," consists of several strategies within three domains, as follows: Domain 1: Engage, Encourage, Support Staff Strategy 1a: Monthly staff huddle with staff recognition activities and compassion-focused rounds Strategy 1b: Compassion training Domain 2: Create a welcome physical environment Strategy 2a: Aesthetic improvements toward a warm, welcoming environment Domain 3: Expedite and augment workflow practices Strategy 3a: Pre-pull patient folders; hold folders for immediate tracking; map patients to identify locations Strategy 3b: Integrate welcome-back services for those who miss follow-up appointments HIV staff at three clinics with below-average retention rates who consent to participate will take part in intervention activities. Results will be compared to those of all other lower-retention clinics within the same health system.
The purpose of the study is to evaluate the reactogenicity, safety, and immunogenicity of an investigational respiratory syncytial virus (RSV) vaccine, mRNA-1345, in pregnant women, and safety and immunogenicity in infants born to vaccinated mothers.
This is a mixed methods study employing a convergence model triangulation design. Participants in the study will be sexually active young adults starting PrEP at private pharmacies, who will be offered either CAB-LA, oral PrEP (TDF/FTC[3TC]), or PrEP deferment at each of their regular visits, with the option to switch between options for up to 15 months, with a final exit interview following the transition to standard-of-care. The number of study visits will vary, depending on participant PrEP choices. Those choosing oral PrEP, will be seen 3 monthly from V2 onwards, but those choosing CAB-LA, will be seen 2 monthly from V2. A maximum of 9 visits is possible.
The goal of this randomized clinical trial is to evaluate safety and biologic effect of a multi-strain vaginal L. crispatus live biotherapeutic product (LBP) in people receiving antibiotic treatment for bacterial vaginosis (BV). The main question[s] it aims to answer are whether the intervention is safe, and whether the strains of L. crispatus will colonize recipients' vagina. The study will evaluate one LBP with 6 strains of L. crispatus (LC106) and one LBP with 15 strains (LC115) vs. placebo. Participants will: - be treated with oral antibiotics for BV - receive 7 days of vaginal study product - collect daily home swabs and make short daily diary entries for 5 weeks, including the week of antibiotic treatment and the week of study product treatment. Researchers will compare the 3 groups receiving different dosing strategies of LC106 and 1 group receiving LC115 vs. 1 group receiving placebo to see if the live biotherapeutic strains colonize the vagina after antibiotic treatment for BV.
Extrapulmonary TB (EPTB) accounts for nearly 30% of TB cases in HIV endemic settings, such as South Africa. The diagnosis of extrapulmonary TB is complicated by the poor performance of Gene Xpert and TB Culture in extrapulmonary fluid (30-50% sensitive), as well as the poor specificity of ADA. We can therefore not reliably use these tests to diagnose EPTB as effectively as we use them in sputum samples. The current best practice for diagnosing pleural TB is to perform a pleural biopsy, which is both invasive and costly. A rapid, easy to use test is needed to allow accurate and fast diagnosis of EPTB. Interferon-gamma is released at high concentrations in extrapulmonary fluid in active EPTB. Antrum Biotech has developed the IRISA-TB assay (validated and SAHPRA licenced) for the diagnosis of EPTB. The study will assess the real-world performance of IRISA-TB compared to ADA, Gene Xpert, and TB Culture when used to diagnose EPTB. We will evaluate IRISA-TB's performance in the following patient groups: - Suspected TB pleural effusion (n= 650) - Suspected TB pericardial effusion (n= 280) - Suspected TB peritonitis (n= 200) - Suspected TB meningitis (n = 1040) As part of our evaluation, we will ask clinicians who treat these patients to provide their feedback on IRISA-TB. We will ask them to indicate to what extent the IRISA-TB test helped them to make treatment decisions. Finally, we will conduct an economic assessment to determine the true cost of diagnosing and treating EPTB to the health system and patients, and we will determine how IRISA-TB could potentially result in cost savings.
The purpose of this study is long-term evaluation of long-acting injectable cabotegravir (CAB LA) for HIV pre-exposure prophylaxis (PrEP) in eligible participants who have completed DAIDS (Division of AIDS) sponsored studies HPTN 083 and HPTN 084 and associated sub-studies. Participants will continue receiving CAB LA and be followed for new HIV diagnosis, SAEs (serious adverse events), Grade 3 and Grade 4 ISRs (injection site reactions), and AEs (adverse events) leading to withdrawal.
This cohort study plans to investigate associations between the presence of multiple lower genital tract microorganisms in pregnancy and gestational age at birth. The study enrols pregnant women at one public health care facility in East London, South Africa. At enrolment and 30-34 weeks of pregnancy, participants provide swabs for testing for sexually transmitted infections, vaginal yeasts and genital mycoplasmas; for microscopy and Nugent scoring; and for 16S ribosomal ribonucleic acid gene sequencing and quantification. The primary outcome is gestational age at birth. Statistical analyses include: regression modelling to explore associations between specific microorganisms (including microbiota) and gestational age at birth; construction of an index of vaginal inflammation, using data about microorganism load and inflammatory potential; classification and regression tree analysis to examine which combinations of microorganisms contribute to earlier gestational age at birth.
