Abstract
Drug–drug interactions between cART and chemotherapy may impact HIV and lymphoma control or lead to increased toxicities. No prospective comparative data informs potential harms and benefits. In AMC034, HIV-associated high-grade B-cell NHL patients received DA-EPOCH with rituximab. cART was given with EPOCH or delayed until chemotherapy completion per investigator choice. Pharmacokinetic, immunological, and treatment effects of concurrent cART were evaluated. CD4 counts dropped during EPOCH in both groups but recovered to higher than baseline 6 months post-EPOCH only in the cART group. HIV viral load decreased during chemotherapy in the cART group but increased in the non-cART group. Incidence of grade ≥3 infectious, hematologic, or neurological toxicities was similar. Concurrent cART was not associated with 1-year EFS or OS. cART with EPOCH was well-tolerated and allowed for faster immune recovery. While we did not observe differences in outcome, the preponderance of evidence is in favor of combining cART with chemotherapy.
