There are about 3576 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 primary objective of this study is to observe the long-term safety of filgotinib in adults who have completed or met protocol specified efficacy discontinuation criteria in a prior filgotinib treatment study in ulcerative colitis (UC).
P1108 is a Phase I/II, open-label, single-arm, exposure-controlled dose finding study of BDQ in infants, children, and adolescents living with and without HIV, with clinically diagnosed or bacteriologically confirmed rifampin-resistant tuberculosis (RR-TB). The study is designed to evaluate the PK, safety, and tolerability of BDQ over 24 weeks.
South Africa has one of the highest rates of violence towards women globally. However, little is known about how to prevent men's use of violence. The Sonke CHANGE Trial tests an intervention that targets men as individuals, groups, and community members in a peri-urban setting in South Africa. Eighteen neighborhoods will be randomly assigned to either the intervention condition or a control group. By speaking to men at baseline, 12 months, and 24 months, investigators will learn whether violence and other health behaviors shift over time. Alongside the trial, qualitative research will explore how the intervention took place and why participants may change attitudes or behaviors.
The main purpose of this study is to evaluate the efficacy of the study drug abemaciclib in postmenopausal women with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) locoregionally recurrent or metastatic breast cancer.

Large genital warts are frequently diagnosed in general gynaecology and oncology clinics in South Africa. Medical and destructive therapy for small warts is generally very effective, however unique problems posed by large or extensive genital warts are not so easily solved and treatment of affected patients remains very challenging. Recurrences are common especially among immune-compromised women. This study will test whether giving the quadrivalent human papilloma virus (HPV) vaccine to women with extensive genital warts prior to surgical treatment will improve outcomes. Investigators hypothesize that pre-treatment with HPV vaccine can play a role in the control of both malignant and benign HPV disease in women with and without HIV infection through stimulation of the antibody response. In addition, HPV types and other associated diseases will be studied in women receiving HPV vaccine and placebo.
Effective tuberculosis (TB) control requires that people who progress from latent Mycobacterium tuberculosis (MTB) infection (LTBI) to TB disease are identified and treated before they infect others. A prognostic correlate of risk (COR), based on messenger ribonucleic acid (mRNA) expression signatures, which prospectively discriminates between TB cases and healthy controls, has been constructed and validated. Based on published microarray case-control datasets, the COR has 87% diagnostic sensitivity and 97% specificity for prevalent TB disease; and in two nested case-control studies, 70% prognostic sensitivity and 84% specificity for incident TB disease occurring within one year of sampling (HIV uninfected persons). Diagnostic and prognostic performance of the COR has not yet been tested in a prospective cohort. COR+ status is not directly associated with LTBI; and may, or may not, be amenable to preventive therapy. Although effective in the short-term, preventive therapy is not recommended for treatment of LTBI in HIV uninfected adults living in high TB burden countries, due to rapid loss of protection; and treatment burden. A 3-month, 12-dose, once-weekly preventive therapy regimen of high dose Isoniazid (INH) and Rifapentine (3HP) has been recommended as equivalent to 6 months of daily INH for treatment of LTBI in low TB burden countries by the World Health Organization (WHO). A 'screen & treat' strategy, based on serial mass campaigns to provide targeted, short-course preventive therapy only to COR+ persons at highest risk of TB disease, may offer the solution for durable, community-wide protection in high TB burden countries. The efficacy of 3HP for prevention of incident TB disease in COR+ persons has not yet been tested in a clinical trial. Primary Aims 1. Test whether preventive therapy (3HP) reduces the rate of incident TB disease, compared to standard of care (active surveillance), in COR+ persons. 2. Test whether COR status differentiates persons with cumulative prevalent or incident TB disease from persons without TB disease. Secondary Aims 1. Estimate whether COR status differentiates persons at high risk for incident TB disease from persons at low risk for incident TB disease 2. Compare prognostic performance of the COR for incident TB disease with Interferon-gamma release assay (IGRA).
This study will evaluate the safety and efficacy of the injectable drug cabotegravir (CAB LA), for pre-exposure prophylaxis (PrEP) in HIV-uninfected cisgender men and transgender women who have sex with men (MSM and TGW).
The purpose of this study was to assess efficacy, including inhibition of radiographic progression, and safety with upadacitinib versus placebo and versus an active comparator, adalimumab, in adults with with moderately to severely active rheumatoid arthritis (RA) who are on a stable background of methotrexate (MTX and who have an inadequate response to MTX.
The main aim of the study is to check for long-term side effects of Vedolizumab Subcutaneous (also known as Vedolizumab SC) in people with ulcerative colitis and Crohn's disease. Vedolizumab SC will be given as an injection just under the skin. This type of injection is called a subcutaneous injection or SC for short. Another aim of the study is to collect information on whether the participant's condition remains under control or improves during and after treatment with Vedolizumab SC. Participants who previously took part in studies MLN0002SC-3027 or MLN0002SC-3031 will be invited to visit the study clinic. At this visit, the study doctor will check if each participant can take part in this study. For those who can take part, participants will receive a subcutaneous injection of vedolizumab SC either once a week or once every 2 weeks. How often each participant receives vedolizumab SC will depend on their results from the previous study and on how active their condition is. Participants might be able to self-inject vedolizumab SC after being trained by the study doctors. During this study, the dose of vedolizumab SC might be increased for participants whose condition worsens. Participants will continue treatment with vedolizumab SC until it is approved in their particular country, the participant decides to stop treatment, or the sponsor stops the study. If the sponsor stops the study before vedolizumab SC is approved in all countries, the sponsor will make sure all affected participants will have access to vedolizumab SC outside of the study. After their final dose of vedolizumab SC, participants will visit the clinic 18 weeks later for a final check-up. Then, the clinic will telephone the participants 6 months after their final dose of vedolizumab SC to check if they have any health problems.
