Optimization of Antiretroviral Therapy in Patients With AIDS-Related Lymphoma

The goal of this clinical trial is to evaluate the efficacy and safety of different antiretroviral therapy (ART) strategies in adults with AIDS-related lymphoma (ARL) receiving anti-lymphoma treatment. The main questions it aims to answer are: Does long-acting injectable ART, including albuvirtide (ABT) or long-acting cabotegravir/rilpivirine (CAB/RPV), improve virological suppression compared with oral ART during anti-lymphoma treatment? Do different ART strategies differ in immune recovery, virological failure, low-level viremia, and safety in patients with ARL? Researchers will compare three treatment strategies-oral ART alone, oral ART plus long-acting albuvirtide (ABT), and long-acting cabotegravir/rilpivirine (CAB/RPV)-to determine whether long-acting injectable ART provides better virological control and comparable safety during lymphoma treatment. Participants will: Receive one of three ART strategies according to their clinical condition and treatment preference while receiving standard anti-lymphoma therapy. Attend scheduled study visits at baseline and Weeks 4, 8, 12, 24, 36, and 48. Undergo plasma HIV-1 RNA testing, CD4+ T-cell count measurement, laboratory assessments, and safety evaluations throughout the 48-week follow-up period. Be monitored for virological suppression, immune recovery, adverse events, and lymphoma-related clinical outcomes.
