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.
This post-marketing study is designed to compare the safety of baricitinib versus tumor necrosis factor (TNF) inhibitors with respect to venous thromboembolic events (VTEs) when given to participants with rheumatoid arthritis.
The researchers are doing this study to look whether the type 2 diabetes medicine, semaglutide, has a positive effect on heart disease. Participants will either get semaglutide tablets or placebo tablets ("dummy" medicine) - which treatment is decided by chance. Participants must take one tablet with water every morning on an empty stomach and not eat or drink anything for at least 30 minutes. The study will last for about 3.5-5 years. Participants will have up to 25 clinic visits and 1 phone call with the study doctor. Women cannot be in the study if pregnant, breast-feeding or if they plan to become pregnant during the study period.
Combination therapy in pulmonary arterial hypertension (PAH) has been the subject of active investigation for more than a decade, with the benefit of targeting different pathways known to be involved in the pathogenesis of the disease. Adherence to prescribed therapy has an impact on clinical outcomes. Reducing the pill/tablet count and frequency has a major impact on patients' adherence to therapies and therefore the observed clinical outcomes. One way to simplify treatment is to use fixed-dose combination (FDC) products that combine multiple treatments targeting different pathways into a single tablet. This study aims to demonstrate that the FDC of macitentan and tadalafil is more effective than therapy with 10 mg of macitentan alone or 40 mg of tadalafil alone. This phase 3 study will evaluate the efficacy and safety at 16 weeks of an FDC (macitentan 10 mg and tadalafil 40 mg) against these two PAH-approved therapies given as monotherapy to further confirm the added value of the FDC.
The investigators will conduct an observational cohort study in 1200 pregnant women who will be recruited at the first antenatal care (ANC) visit from the Gugulethu and one additional facility in the Klipfontein-Mitchell's Plain subdistrict of the Metro Region (to be identified in conjunction with provincial and local health authorities) Midwife Obstetric Units in Cape Town (n=600 pregnant women per site). The enrolled women will be followed through 12-months post-delivery.
This clinical study will evaluate the short-term (1- and 2-year) and medium term (5-year) safety and performance of the ANTHEM™ CR Total Knee System in patients with non-inflammatory degenerative joint disease of the knee requiring total knee replacement. Clinical, radiographic, Health Economic Outcomes and safety outcomes will be evaluated.
This study evaluates the duration of intraocular pressure (IOP)-lowering effect and safety of as needed administrations of Bimatoprost sustained release (SR) in participants with open-angle glaucoma (OAG) or ocular hypertension (OHT) who are not adequately managed with topical IOP-lowering medication for reasons other than medication efficacy.
The purpose of this study is to evaluate the efficacy and safety of acalabrutinib in combination with venetoclax and acalabrutinib in combination with venetoclax with and without obinutuzumab compared to chemoimmunotherapy in subjects with previously untreated CLL
QT interval prolongation and neutropenia are considered to be important identified risks for ribociclib. The approved dosing regimen of ribociclib is 600 mg daily (QD) on a 3 weeks on/1 week off schedule. The purpose of the study is to explore whether a reduced dosing regimen of 400 mg ribociclib orally QD 3 weeks on/1 week off may decrease the risk of QTc prolongation without compromising the efficacy of ribociclib in combination with a non-steroidal aromatase inhibitor (NSAI) in pre- and postmenopausal women with hormone receptor-positive (HR-positive), HER2-negative advanced breast cancer (aBC) who have not received prior therapy for advanced disease.
The purpose of this study is to assess the safety and efficacy of pembrolizumab (MK-3475) combined with lenvatinib (MK-7902/E7080) compared to pembrolizumab alone (with placebo for lenvatinib) as first-line treatment in adults with no prior systemic therapy for their advanced melanoma. The primary study hypotheses are that: 1) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1), and 2) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Overall Survival (OS). For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ.
The researchers are doing this study to see if semaglutide can slow down the growth and worsening of chronic kidney disease in people with type 2 diabetes. Participants will get semaglutide (active medicine) or placebo ('dummy medicine'). This is known as participants' study medicine - which treatment participants get is decided by chance. Semaglutide is a medicine, doctors can prescribe in some countries for the treatment of type 2 diabetes. Participants will get the study medicine in a pen. Participants will use the pen to inject the medicine in a skin fold once a week. The study will close when there is enough information collected to show clear result of the study. The total time participants will be in this study is about 3 to 5 years, but it could be longer.
