NCT ID: NCT06285110 Recruiting - Hiv Clinical Trials

HIV-1 Subtype-specific Drug Resistance in Patients Failing Dolutegravir (DTG) Based Regimen

DTG-Resist
Start date: June 13, 2022
Phase:
Study type: Observational

This is a prospective observational study enrolling People Living with HIV (PLHIV) who are on a Dolutegravir-based AntiRetroviral Treatment (ART) regimen and experiencing virologic failure. Virologic failure is defined as two consecutive viral load measurements of >1000 copies/mL of blood. The main aim of the study is to identify the drug-resistance mutations in the viral genome that are associated with this failure. To achieve this goal, patients fulfilling the eligibility criteria will be invited for a single study visit for the collection of blood. The extracted HIV virus will be sequenced through whole genome sequencing methods to identify the drug-resistance mutations. The study is conducted in 15-20 countries within six regions of the IeDEA cohort (International epidemiology Databases to Evaluate AIDS).

NCT ID: NCT06253715 Not yet recruiting - Tuberculosis Clinical Trials

Shortened Regimen for Drug-susceptible TB in Children

SMILE-TB
Start date: September 30, 2024
Phase: Phase 3
Study type: Interventional

While drug-susceptible tuberculosis (TB) disease in children currently requires four to six months of treatment, most children may be able to be cured with a shorter treatment of more powerful drugs. Shorter treatment may be easier for children to tolerate and finish as well as ease caregiver strain from managing treatment side effects and supporting children over many months. The primary objective of this study is to evaluate if a 2-month regimen (including isoniazid (H), rifapentine (P), pyrazinamide (Z) and moxifloxacin (M)) is as safe and effective as a 4- to 6-month regimen (isoniazid, rifampicin (R), pyrazinamide, ethambutol (E)) in curing drug-susceptible TB disease in children under 10 years old. The study is also evaluating the safety of the HPZM in children with and without HIV.

NCT ID: NCT06226636 Recruiting - High Blood Pressure Clinical Trials

Immediate Pressor Response to Oral Salt

IPROS
Start date: July 7, 2023
Phase: N/A
Study type: Interventional

The goal of this study is to establish a diagnostic accuracy of an immediate pressor response to oral salt (IPROS) to identify salt sensitivity of blood pressure (SSBP)

NCT ID: NCT06166498 Not yet recruiting - Malaria Clinical Trials

Parasite Clearance and Protection From Infection (PCPI) in Zambia

Start date: February 15, 2024
Phase: Phase 3
Study type: Interventional

The Zambia PCPI study will measure the effect of the parasite genotypes associated with SP resistance on parasite clearance and protection from infection when exposed to SP. The total number of participants is expected to be 600 healthy between 3 to 5 years old who have no symptoms of malaria infection of which 400 children will be assigned to the SP group and 200 to the AS group. The results of this study will allow to measure the effect of the parasite genotypes associated with SP resistance on parasite clearance and protection from infection when exposed to SP.

NCT ID: NCT06135818 Recruiting - Clinical trials for Tuberculosis, Extrapulmonary

Same Day Diagnosis of Extrapulmonary TB (TB Serositis and TB Meningitis).

Epi-TB
Start date: March 16, 2021
Phase: N/A
Study type: Interventional

Extrapulmonary TB (EPTB) accounts for nearly 30% of TB cases in HIV endemic settings, such as South Africa. The diagnosis of extrapulmonary TB is complicated by the poor performance of Gene Xpert and TB Culture in extrapulmonary fluid (30-50% sensitive), as well as the poor specificity of ADA. We can therefore not reliably use these tests to diagnose EPTB as effectively as we use them in sputum samples. The current best practice for diagnosing pleural TB is to perform a pleural biopsy, which is both invasive and costly. A rapid, easy to use test is needed to allow accurate and fast diagnosis of EPTB. Interferon-gamma is released at high concentrations in extrapulmonary fluid in active EPTB. Antrum Biotech has developed the IRISA-TB assay (validated and SAHPRA licenced) for the diagnosis of EPTB. The study will assess the real-world performance of IRISA-TB compared to ADA, Gene Xpert, and TB Culture when used to diagnose EPTB. We will evaluate IRISA-TB's performance in the following patient groups: - Suspected TB pleural effusion (n= 650) - Suspected TB pericardial effusion (n= 280) - Suspected TB peritonitis (n= 200) - Suspected TB meningitis (n = 1040) As part of our evaluation, we will ask clinicians who treat these patients to provide their feedback on IRISA-TB. We will ask them to indicate to what extent the IRISA-TB test helped them to make treatment decisions. Finally, we will conduct an economic assessment to determine the true cost of diagnosing and treating EPTB to the health system and patients, and we will determine how IRISA-TB could potentially result in cost savings.

NCT ID: NCT06129253 Not yet recruiting - HPV Infection Clinical Trials

Global Burden Estimation of Human Papillomavirus (GLOBE-HPV)

HPV
Start date: November 2023
Phase:
Study type: Observational

This study is a multi-country and multi-site project to estimate the point-prevalence of high-risk (HR) HPV genotype infections among representative samples of girls and women aged 9-50 years, and among specific sub-populations to estimate the incidence of persistent HPV infection among sexually active young women. The data to fulfill the objectives will be collected through a series of Cross-Sectional Surveys (CSS) and Longitudinal Studies (LS) in all 8 countries 3 South Asian countries including Bangladesh, Pakistan, Nepal and 5 sub-Saharan African countries including Sierra Leone, Tanzania, Ghana, Zambia and DR Congo. Qualitative sub-studies (QS) will be conducted in selected countries and populations following the CSS to further understand and unpack risk factors for HPV infection as well as to explore how gender-related dynamics including perceptions of gender norms and stigma, influence HPV burden and/or create barriers that shape girls/women access to and uptake of HPV prevention, screening, and treatment services. Specific study protocols and corresponding ethical applications for the qualitative sub-studies will be developed separately.

NCT ID: NCT06062238 Recruiting - Tuberculosis Clinical Trials

Study to Assess Efficacy and Safety of M72/AS01E-4 Mycobacterium Tuberculosis (Mtb) Vaccine in Adolescents and Adults
