NCT ID: NCT04832932 Active, not recruiting - COVID-19 Vaccines Clinical Trials

The COVID-19 Back-to-Normal Study: Analysis of Multiple Outcomes

Start date: January 5, 2021
Phase:
Study type: Observational

During the study, members of different online and offline communities will be followed post COVID-19 vaccination. Injection-site (local) and systemic reaction data will be assessed on vaccination day and afterwards using either web surveys or personal communication, depending on study participant preference. Hypothesis to be tested: The safety profile and the magnitude and durability of immune responses to the COVID-19 vaccines as well as adverse reactions depend on health conditions, metabolism and microbiomes.

NCT ID: NCT04826094 Completed - HIV Infections Clinical Trials

A Study to Assess the Safety and Immune Response to Env-C DNA and Protein Vaccines in Kenya

Start date: March 15, 2021
Phase: Phase 1
Study type: Interventional

This is a study of HIV vaccines. A vaccine is a medical product given to prevent certain diseases. The vaccine may educate the body to form a defensive response to try to prevent the disease from the beginning, or preventing it from taking hold of the body. This defensive response is called the immune response. The experimental vaccines in this study are Env-C Plasmid DNA and HIV Env gp145 C690 protein, given with different adjuvants. An adjuvant is a substance added to vaccines that can help make the vaccine more effective by improving the immune response, or by causing the immune response to last longer than it would without the adjuvant. The adjuvants are mixed with the vaccines and injected into muscle or placed on top of the skin. The HIV vaccines contain a piece of genetic material or a protein copied drom the HIV virus cover (Env), but they do not contain the virus itself. The vaccines cannot cause HIV infection or Acquired Immune Deficiency Syndrome (AIDS). The purpose of this study is to find out if the study vaccines with adjuvants cause side effects and are tolerable, whether humans respond (develop immune responses) to the vaccines, and how ling the effects of the study vaccines last. The study will also compare the effects of the study vaccines with adjuvants and adjuvant patch to those of placebo injections and placebo patch. The placebo will consist of saline (sterile saltwater) and will look like study vaccines, be given in the same way, but will have no active vaccine or adjuvant in it. A total of 126 participants will take part in the study and each will have up to 26 clinic visits and will be followed-up for a total of 108 weeks.

NCT ID: NCT04825782 Recruiting - Pregnancy Related Clinical Trials

MiMBa Pregnancy Registry

Start date: February 22, 2021
Phase:
Study type: Observational

The MiMBa (Malaria in Mothers and Babies) Pregnancy Registry aims to generate robust evidence on the safety of a range of antimalarials when used in pregnancy, particularly in the first trimester. This will be a multi-country observational study and will be deployed in several field sites in Africa.

NCT ID: NCT04814927 Completed - Clinical trials for Mucosal Inflammation

Impact of Contraceptives on Cervico-Vaginal Mucosa

UMPALA
Start date: March 1, 2021
Phase: Phase 4
Study type: Interventional

UMPALA is a research study to look at the effect of four different, approved contraceptives on the cervical and vaginal tissues as well as on factors in the blood. Participants will have a baseline examination then receive one of four approved, marketed contraceptive products. Cervico-vaginal assessments will take place 4 weeks after contraceptive initiation and 3 months after to assess changes in mucosal safety after use of various contraceptive products in young, healthy, HIV uninfected women.

NCT ID: NCT04814680 Completed - Clinical trials for Prediction of Blood Pressure, Glycated Haemoglobin and Estimated Glomerular Filtration Rate From Digital Retinal Images

Machine-Learning Algorithm for Prediction of Blood Pressure, Glycated Haemoglobin and Estimated Glomerular Filtration Rate

Start date: November 8, 2021
Phase:
Study type: Observational

This is a non-interventional pilot study with the following objectives: - Establish scalable methodology for collection of retinal images, blood pressure (BP) and laboratory-based assessments - Compare the results of a machine-learning algorithm in predicting BP, glycated haemoglobin (HbA1c) and estimated glomerular filtration rate (eGFR) from digital retinal images with clinical and laboratory-based measures - Determine the required sample size needed to support a future study to fully validate the machine-learning algorithm

NCT ID: NCT04813159 Recruiting - STEMI Clinical Trials

Remote Ischaemic Conditioning in STEMI Patients in Sub-Saharan AFRICA

RIC-AFRICA
Start date: January 12, 2022
Phase: N/A
Study type: Interventional

The RIC-AFRICA trial is a multi-centre, sham-controlled, double-blinded, randomised controlled trial (RCT) involving 1200 ST-segment elevation myocardial infarction (STEMI) patients presenting within ≤ 24 hours of myocardial infarction (MI) onset, across approximately 20 sites in four sub-Saharan African countries (South Africa, Kenya, Sudan and Uganda). Patients presenting with STEMI and deemed ineligible for the RIC AFRICA RCT because they present >24 hours from MI onset but less than 72 hours, will be recruited into the observational arm of the study with the same endpoints as the trial. The purpose of the RCT is to determine whether Remote Ischaemic Conditioning (RIC) can reduce the rates of all-cause death and early post-myocardial heart failure at 30-days in STEMI patients treated predominantly with thrombolytic therapy.

Start date: March 2, 2021
Phase: N/A
Study type: Interventional

This randomized controlled trial will assess the feasibility, acceptability and impact of the provision of multiple oral-fluid based HIV self-test kits to HIV-negative adolescents aged 15-19 years to promote HIV testing among their sexual partners and couples testing.

NCT ID: NCT04801602 Completed - Typhoid Fever Clinical Trials

Commercial Typhoid Tests Validation Trial

Start date: October 25, 2020
Phase:
Study type: Observational

Typhoid fever (typhoid) is an enteric bacterial infection caused by Salmonella enterica serovar Typhi (Salmonella Typhi; S. Typhi). It is one of the most common bacterial causes of acute febrile illness in the developing world, with an estimated 10.9 million new cases worldwide and 116.8 thousand deaths in 2017. Like many febrile illnesses, typhoid presents with non-specific symptoms and signs, especially in its early stages. In routine healthcare settings in low- and middle-income countries (LMIC), typhoid fever is commonly suspected and treated empirically with antibiotics. This overuse of antibiotics creates a selective pressure for the development of antimicrobial resistance (AMR), that has resulted in the emergence and spread of typhoid strains that are resistant to all first-line antibiotics. Similarly, the low specificity of current rapid diagnostic tests (RDTs) can lead to an over diagnosis of typhoid fever that may result in the overuse of antibiotics and delay the proper treatment for underlying conditions. FIND in collaboration with international typhoid experts developed a target product profile outlining the ideal characteristics of point of care tests. As part of this activity it became apparent that no quality data are available that systematically compare all available commercially point of care tests against the same set of reference standards used in multiple populations (e.g. Africa vs Asia). This lack of benchmarking data significantly impedes health provider's ability to decide on the utility of commercial tests in different settings, ultimately restricting use and access. Further the lack of well characterized samples reduces the ability for targeted innovation in the typhoid space. The current study aims to benchmark different commercial typhoid tests against a defined reference standard applied in multiple population and simultaneously develop a sample set that can be used in future evaluations of emerging technologies and/or to support innovative test development.
