PREVAIL VIIIa: Evaluation of Latent Tuberculosis Infection Screening Methods in People Living With Retroviral Infection in Liberia
NCT04926922 · View on ClinicalTrials.gov ↗
Study Summary
Background: Tuberculosis (TB) is a health threat for people living with human immunodeficiency virus (HIV). People living with HIV are more likely than others to develop active TB. Also, TB makes HIV progress faster. TB is a leading cause of death among people in the West African country of Liberia. Researchers want to find an effective testing method for latent tuberculosis infection (LTBI) to help people living with HIV in Liberia. Objective: To compare the interferon-gamma release assay (IGRA) and tuberculin skin test (TST) as LTBI screening tests in people living with HIV in Liberia. Eligibility: People ages 18 and older who take part in NIH study #19-I-N014 and are scheduled to have or have had IGRA at a Month 12 HONOR study visit. Design: Participants will be screened with a medical history and physical exam. Their medical records and HONOR study records will be reviewed. Participants will have TST. Purified protein derivative will be placed in the skin of their forearm. They will be observed for adverse reactions for 15 minutes. Between 48 and 72 hours after placement, they will have a second study visit to have the TST read. If they miss this time frame, they can return up to 7 days after placement. If they have a positive test result, they will have a chest x-ray. They will have a third study visit to review the results of the chest x-ray. They will be referred for clinical care if needed. They will take a pregnancy test if needed. Participation will last from 2 days to 6 weeks. ...

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04926922
The ClinicalTrials.gov registry entry for NCT04926922 describes a study currently listed as active not recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 200 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Allergy and Infectious Diseases (NIAID), which has 1,295 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with HIV appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04926922 reports 5 study locations spanning 2 distinct geographic areas — top geographies include Other, Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
