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 purpose of the study is to evaluate the safety and efficacy of talazoparib in combination with enzalutamide compared with placebo in combination with enzalutamide in participants with DDR-deficient mCSPC.
A Phase 3 study to evaluate the safety and efficacy of efgartigimod PH20 subcutaneous in adult patients with primary immune thrombocytopenia
The main objectives of CESTA are (1) to compare the efficacy of two cervical cancer screening algorithms: HPV test followed by visual inspection with acetic acid (VIA) and treatment (HPV + VIA + treat) and HPV test followed by immediate treatment (HPV + treat). The study will be conducted to address its objectives in women living with HIV (from now on called HIV positive women); and 2) To evaluate the performance of other techniques for primary screening and as triage for HPV positives WLHIV. 1,500 women living with HIV WLHIV will be recruited from HIV care clinics, also called antiretrovirals (ARV) clinics in South Africa. After giving informed consent, women will be screened with HPV testing and those that have a HPV positive test will be randomized at a 4:1 ratio into HPV + VIA + treat (Arm 1) and HPV + treat (Arm 2). Women in Arm 1 will receive VIA and only positive for VIA will be treated. In Arm 2, all HPV positive women will be treated. Women that are eligible for ablative treatment will be randomized into treatment with TA or cryotherapy in both arms. Others will be referred to colposcopy. After VIA in Arm 1 or before treatment in Arm 2, the nurses will collect 2-4 biopsies on all HPV positive women. The biopsies will be used as gold standard for disease detection. Treated women will be called by telephone after 1 week and 1 month to assess side-effects and satisfaction with the procedures. Cervical samples from women will be tested with HPV DNA test and HPV mRNA test to evaluate different screening tests for WLHIV. All women with a positive HPV test (treated or not) will be called back after 1 year for a follow-up visit. At this visit, women will be screened with HPV testing and VIA and 2-4 colposcopy-directed biopsies will be taken from all HPV positive women. Women with remaining/recurrent CIN2+ disease will receive appropriate management.
The study will evaluate the efficacy and safety of trastuzumab deruxtecan (also known as T-DXd, DS-8201a), either alone or in combination with pertuzumab, in treating patients with Human epidermal growth factor receptor 2 (HER2)-positive breast cancer as a first line of treatment in the metastatic setting.
A randomized, crossover study to compare adherence, preference and acceptability of an over-encapsulated dual prevention pill (DPP capsule) containing oral pre-exposure prophylaxis (PrEP) and a combined oral contraceptive (COC) versus two separate tablets (PrEP and COC) among women at risk of HIV and unintended pregnancy in Johannesburg, South Africa
This study is done to find out whether the medicine, semaglutide, has a positive effect on early Alzheimer's disease. Participants will either get semaglutide or placebo (a "dummy" medicine which does not contain any study medicine) - which treatment participants get is decided by an equal chance. The study will last for up to 173 weeks (about 3 years and 4 months). Participants will have 17 clinic visits and 1 phone call with the study doctor. The study includes various tests and scans. At 10 of the clinic visits participants will have blood samples taken. Participants must have a study partner, who is willing to take part in the study. Women cannot take part if pregnant, breastfeeding or plan to become pregnant during the study period. A cerebrospinal fluid (CSF) sub-study will be performed as a part of the study. The sub-study will be performed on a selection of sites based on their experience with CSF sampling and willingness to participate in this sub-study. The endpoints related to this sub-study are exploratory only.

The safety and tolerability of MK-8591A, a 2-drug fixed dose combination (FDC) of doravirine (DOR 100mg) and islatravir (ISL 0.75mg) will be evaluated in participants with Human Immunodeficiency Virus -1 (HIV-1) who were treated with DOR and ISL in earlier clinical studies.
The primary objectives of this phase 2b/3 double-blind, randomized, placebo-controlled study are to evaluate the efficacy and safety of clesrovimab in healthy pre-term and full-term infants. It is hypothesized that clesrovimab will reduce the incidence of respiratory syncytial virus (RSV)-associated medically attended lower respiratory infection (MALRI) from Days 1 through 150 postdose compared to placebo.
To achieve an AIDS-free generation, there is a critical need for programs which go beyond individual-level behavior change to reduce HIV and STI infections among adolescent girls and young women in sub-Saharan Africa. Informed, Motivated, Aware, and Responsible Adolescents and Adults (IMARA) is an evidence-based HIV-prevention intervention for adolescent girls and young women (AGYW) and their female caregivers, which has been adapted for a South African audience. The study will test whether AGYW receiving IMARA will have fewer sexually-transmitted infections (STI) and greater acceptance of HIV testing and counseling (HTC) and pre-exposure prophylaxis (PrEP) at 6-month follow-up compared to AGYW assigned to the health-promotion control intervention.
