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 this clinical trial is to learn about the safety, extent of the side effects, and immune responses of the study vaccine (called variant-adapted BNT162b2 RNA-based vaccine) in healthy children. The trial is divided into 5 individual studies or substudies based on age group and prior history of COVID-19 vaccinations. All participants in each of the 5 sub-studies will receive study vaccine as a shot depending on what group they are in. - Substudy A design: Phase 1 includes participants 6 months through less than 4 years 3 months of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naïve) and will receive 3 doses of study vaccine as their initial series, followed by a fourth dose of study vaccine. Phase 2/3 includes participants 6 months through less than 5 years of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naive) and will receive 1, 2, or 3 doses of study vaccine, depending on what group they are in. - Substudy B design: includes participants 6 months through less than 5 years of age who have either received 2 or 3 prior doses of BNT162b2 and will receive study vaccine as their third or fourth dose. - Substudy C design: Phase 1 includes participants 6 months through less than 5 years of age who have received 3 prior doses of BNT162b2 and will receive study vaccine as their fourth dose. - Substudy D design: includes participants 5 through less than12 years of age who have received 2 or 3 prior doses of BNT162b2 and will receive study vaccine as their third or fourth dose. - Substudy E design: includes participants 2 through less than 12 years of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naive) and will receive a single dose of study vaccine.
Tuberculosis (TB) is the biggest infectious cause of death worldwide, and the biggest cause of death in Sub-Saharan Africa among HIV-positive patients. There is need for a non-sputum-based rapid triage test that identifies individuals with presumptive TB requiring confirmatory diagnostic investigation. Such a test could reduce the burden on health systems, expedite referral and confirmatory testing, and treatment thereby reducing transmission. A non-sputum triage test is needed as many symptomatic patients including those with HIV, can often not produce high quality sputum (which most current diagnostics rely on). Several blood transcriptional diagnostic signatures produced due to immune responses to M. tuberculosis infection have previously been described, however there is lack of real-world performance data especially in high TB/HIV-endemic African settings where rates of HIV (that could compromise sensitivity) and previous TB (that could compromise specificity) are high. Furthermore, by building on prior research that used untargeted sequencing approaches to identify candidate signatures, the investigators are now at a stage to perform the targeted signature measurement at a large scale and cost-efficient manner as part of prospective diagnostic accuracy analyses in real-world settings. Using the framework provided by an EDCTP-funded parent study (SeroSelectTB; PI Holm-Hansen), which is a pan-African evaluation of a point-of-care serological test for active TB, RADIANT has a unique opportunity to pursue several important research questions. RADIANT aims are to 1) evaluate the sensitivity and specificity of selected concise peripheral host transcriptional signatures for active TB among symptomatic persons in South Africa; 2) design a cost-optimised diagnostic algorithm based on transcriptional signatures, SeroSelectTB results, and confirmatory bacteriological testing, and 3) characterise bacteriologically-negative patients classified as non-TB to determine if those with elevated host transcriptional signatures (n=100 expected) have other respiratory pathogens (detected in nasopharyngeal swabs using a commercial multiplex panel) and/or develop active TB within six months (incident active TB).
The purpose of the study is to evaluate the long term safety and efficacy of orally administered M5049 in participants with subacute cutaneous lupus erythematosus (SCLE), discoid lupus erythematosus (DLE) and/or systemic lupus erythematosus (SLE) who have completed the 24 week treatment period of Willow study (MS200569_0003 [NCT05162586]).
A5418 is a randomized, placebo-controlled, double-blind study to establish the efficacy of tecovirimat for the treatment of people with laboratory-confirmed or presumptive HMPXV disease.
The main objectives of the trial are to assess the efficacy and safety of trimodulin as adjunctive treatment to standard of care (SoC) compared to placebo plus SoC in adult hospitalized subjects with non-severe community-acquired pneumonia (CAP) or moderate / severe Coronavirus Disease 2019 (COVID-19) pneumonia. Other objectives are to determine pharmacokinetic (PK) and pharmacodynamic (PD) properties of trimodulin.
According to WHO, about 40% of the incident TB cases in 2020 are either under-reported or under-diagnosed causing on one hand major health risks and on the other hand catastrophic financial consequences. In particular, indigent people in hard-to-reach communities with high TB/HIV burden are at high risk of missed or delayed diagnoses. Hence, active case finding for TB remains an integral part of tuberculosis control in high-risk groups, such as people living with HIV (PLHIV) or diabetes mellitus, people living in specific geographical locations associated with a high burden of TB and poor access to health care, miners, or prisoners. CAD4TB (Delft Imaging, NL), a digital chest X-ray analysis software, and point-of care C-reactive protein assay (POC-CRP; e.g. LumiraDx, UK), which detects a cytokine induced acute phase protein, are two tests which have great potential of becoming a screening and triage test for TB as outlined in the WHO target product profiles. Data on CAD4TB and CRP suggest that accuracy can be improved if thresholds are stratified by patient characteristics, such as HIV status, history of TB and TB symptoms. TB TRIAGE+ Trial takes place in the communities of Lesotho and South Africa, which present high prevalence of subclinical TB, where a symptom-based screening would miss almost half of all infectious TB cases. TB TRIAGE+ Trials conducts a direct (in the same individual) comparison of the two screening/triaging approaches which are not based on symptoms: CAD4TB screening alone (approach 1) versus CAD4TB screening with POC-CRP triage testing (approach 2), and followed by confirmatory Xpert MTB/RIF Ultra testing in both approaches. TB TRIAGE TRIAL is investigates the hypothesis that a community-based active case finding strategy with CAD4TB screening with POC-CRP triage testing (approach 2) will be non-inferior compared to CAD4TB screening alone (approach 1) with regard to yield of detected TB cases and superior with regard to cost effectiveness.
The purpose of this study is to assess the long-term safety and tolerability of aticaprant administered as adjunctive therapy to a current antidepressant (selective serotonin reuptake inhibitor [SSRI] or serotonin and norepinephrine reuptake inhibitor [SNRI]) in all participants with major depressive disorder (MDD).
This is a multicenter, randomized, observer blind clinical trial. A total of 750 evaluable HIV-infected (660) and HIV-uninfected (90) adult participants meeting all entry criteria (all inclusion and no exclusion criteria) will be enrolled in 3 treatment strategies in 3 participant groups dependent on prior vaccination with a single dose Janssen (Group 1), 2 doses of Pfizer (Group 2) or no prior COVID-19 vaccination with evidence of prior SARS-CoV-2 infection (Group 3) .A total of 300 participants per group will be enrolled in Groups 1 and 2 (255 HIV-infected and 45 HIV-uninfected per group), and 150 HIV-infected, unvaccinated participants in Group 3. Each treatment regimen (Vaccine Arm: A, B or C) will evaluate 250 participants. Groups 1 and 2 will enrol 85 HIV-infected and 15 HIV-uninfected per vaccine arm.
This study compares semaglutide, together with a lower dose of insulin glargine, to a higher dose of insulin glargine in participants with type 2 diabetes. The study looks at how well the study medicines control blood glucose levels. Participants will either get semaglutide together with a lower dose of insulin glargine or a higher dose of insulin glargine. The study will last for about 47 weeks (approximately 11 months). Participants will have 9 clinic visits, 15 phone/video calls and 1 home visit. Participants will be asked to wear a sensor that measures their blood sugar all the time in 2 periods of 10 days during the study.
The purpose of this extension study is to collect long-term efficacy, safety and tolerability data on remibrutinib in a selected group of participants with Chronic Spontaneous Urticaria (CSU) who previously completed the treatment phase of remibrutinib preceding Phase 3 studies. This study will also fulfill the Novartis commitment to provide post-trial access to participants who have completed the preceding Phase 3 studies, where applicable.
