What this trial studies

This observational study evaluates the real-world effectiveness of Lenacapavir, a novel capsid inhibitor, as an add-on treatment to an optimized background regimen for adults with multidrug-resistant HIV-1 infection in France. Participants who have received Lenacapavir since its availability on June 20, 2023, will have their data collected to assess viral suppression and overall health outcomes. The study aims to gather insights on the long-term efficacy and safety of Lenacapavir in a clinical setting, contributing to better management strategies for patients with treatment-resistant HIV.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients with multidrug-resistant HIV-1, improving their viral suppression and overall health.

How similar studies have gone: Previous studies, including the CAPELLA trial, have shown promising results with Lenacapavir, indicating its potential effectiveness in treating multidrug-resistant HIV-1.
