What this trial studies

This observational study investigates how well people living with HIV in Indonesia adhere to their antiretroviral therapy, specifically focusing on tenofovir-based regimens. It employs multiple methods to measure adherence, including self-reports, pill counting, and electronic monitoring, alongside drug-level testing in various biological matrices. The study aims to correlate adherence levels with tenofovir concentrations in plasma, urine, saliva, and dried blood spots, while also assessing clinical outcomes like viral load and CD4 count. By developing assays for measuring drug concentrations, the research seeks to enhance understanding of adherence and its impact on treatment efficacy.

Who should consider this trial

Good fit: Ideal candidates are adults living with HIV who have been on tenofovir-based antiretroviral therapy for at least six months.

Not a fit: Patients who are pregnant, breastfeeding, have kidney failure, or uncontrolled chronic conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for monitoring and enhancing medication adherence in HIV patients, ultimately improving health outcomes.

How similar studies have performed: Other studies have shown success in using biological matrices for adherence monitoring, making this approach promising yet still evolving.
