NCT ID: NCT05551273 Recruiting - HIV Infections Clinical Trials

Study of Oral TLR8 Agonist Selgantolimod on HBsAg in Participants With Both Chronic Hepatitis B and HIV

Start date: December 14, 2022
Phase: Phase 2
Study type: Interventional

The study aims to assess safety and tolerability of oral toll-like receptor (TLR) 8 agonist Selgantolimod (SLGN) administered for 24 weeks in participants with both CHB and HIV who have been receiving suppressive antiviral therapy for both viruses for ≥5 years and have qHBsAg level >1000 (3 log10) IU/mL at screening. The study will also evaluate if TLR8 stimulation with SLGN will reduce hepatitis B surface antigen (HBsAg) titers in the blood.

Study type: Interventional

The purpose of this study is to assess the efficacy of topical emollient treatments in improving neonatal growth and mortality rates.

NCT ID: NCT05458765 Recruiting - Clinical trials for Adherence, Medication

Project Engage: Oral PrEP Acceptability

Start date: June 21, 2022
Phase: Phase 2
Study type: Interventional

This study is a two-arm open label acceptability study that will examine acceptability of, and adherence to, once daily dosing regimen of F/TDF (Truvada) and an investigational once daily dosing regimen of F/TAF (Descovy) under standard of care counselling. The study will recruit approximately 330 healthy, HIV negative, AGYW in up to three sites in Africa. Eligible participants will be randomized 1:1 to receive F/TAF 200 mg/25 mg or F/TDF 200 mg/300 mg for once daily oral administration for 24 weeks. Study visits will take place according to standard of care at month 1, month 3 and month 6. Acceptability and adherence will be assessed by questionnaires and DBS at months 3 and 6; questionnaires will assess acceptability of product attributes; perceived pill side effects; ease of pill-taking and reasons for missed pills, and future interest in PrEP use beyond the trial context. Exit interviews at the final visit and additional qualitative interviews and focus group discussions with a subset of participants as well as other key stakeholders will further inform potential differences in acceptability and adherence between the two products. Data collection will also focus on gathering insights and input from participants that will aid uptake and continuation and inform future programming of oral PrEP.

NCT ID: NCT05383742 Not yet recruiting - Clinical trials for Tuberculous Meningitis

Trial of a Six-Month Regimen of High-Dose Rifampicin, High-Dose Isoniazid, Linezolid, and Pyrazinamide Versus a Standard Nine-Month Regimen for the Treatment of Adults and Adolescents With Tuberculous Meningitis

Start date: March 1, 2023
Phase: Phase 2
Study type: Interventional

The purpose of this study is to compare a 6-month regimen of high-dose rifampicin (RIF), high-dose isoniazid (INH), linezolid (LZD), and pyrazinamide (PZA) versus the World Health Organization (WHO) standard of care (SOC) treatment for tuberculosis meningitis (TBM).

NCT ID: NCT05278559 Recruiting - HIV/AIDS Clinical Trials

Can Undetectable (Viral Load) = Untransmissible (Virus) Change the Life Course of Adolescents Living in Africa

Start date: March 24, 2022
Study type: Observational

The scientific breakthrough related to Undetectable (viral load) = Untransmissible (virus) has had a major impact on motivation to take up and adhere to antiretroviral therapy among people living with HIV all over the world. The aim of the study is to work with MoHCC and other stakeholders to explore whether routine VL testing using DBS can provide sufficiently robust evidence of 'undetectability' to support introduction of U=U messaging in ALHIV. The study will provide scientific evidence on whether routine VL testing using DBS as available in LIC can provide sufficiently robust evidence of 'undetectability' and on the variability of an individual's virological response over 12 months. It will provide contextually orientated evidence to inform U=U messaging which has the potential to change the motivation of ALHIV to engage with their treatment and care.It will also explore responsible ways to disseminate this message to ALHIV living in Zimbabwe, and across the Southern African region.

NCT ID: NCT05220163 Recruiting - HIV Infections Clinical Trials

Evaluating the Impact of Computer-assisted X-ray Diagnosis and Other Triage Tools to Optimise Xpert Orientated Community-based Active Case Finding for TB and COVID-19

Start date: February 23, 2022
Phase: N/A
Study type: Interventional

Tuberculosis (TB) is now the commonest cause of death in many African countries. Globally, ~35% (almost 1 in 3) of TB cases are 'missed' (remain undiagnosed or undetected). In sub-Saharan Africa, 40-50% of the TB case burden remains undiagnosed within the community. These 'missed' TB cases (at primary care level) serve as a reservoir, which severely undermines TB control. With rapid advances in the development of TB screening tests, the investigators aim to determine the pragmatic utility of computer-assisted x-ray diagnosis (CAD). Recent data suggest that CAD performs on par with experienced radiologists to identify potential TB cases, hereby reducing the frequency at which Xpert tests are requested and helps to focus limited resources on the relevant cases. In addition, the investigators aim to test nascent screening technologies for TB diagnosis such as evaluating urine-based TB screening biosignatures. The COVID-19 pandemic has ravaged African peri-urban communities where TB is also common. With the pressing need to improve screening and diagnosis of COVID-19, the investigators plan to explore the potential for urine- and blood-based COVID-19 screening assays. Symptoms of COVID-19 and TB overlap, and limited affordability, as well as the stigma associated with both diseases, severely limits testing. Data are now urgently needed about the feasibility of co-screening and testing for TB and COVID-19. The utility of such an approach, if any, has not been studied in African communities.

NCT ID: NCT05184452 Active, not recruiting - HIV Infections Clinical Trials

A Clinical Trial to Evaluate the Safety, Tolerability, and Pharmacokinetics of PGDM1400LS Alone and in Combination With VRC07-523LS and PGT121.414.LS in Healthy, HIV-uninfected Adult Participants

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

Part A: The purpose of this part of the study is to understand how the body's immune system responds to a new lab-made antibody against HIV. The study is looking to see if the way the antibody is given affects the immune response. The study will also look at whether the antibody is safe to give to people and does not make them too uncomfortable. Part B: The purpose of this part of the study is to understand how the body's immune system responds to lab-made antibodies against HIV when they are given in combination at different doses. The study also wants to see if the way the antibodies are given affects the immune response.
