Official Title: Feasibility Study of CO-administering Combination Antiretroviral Therapy (cART) and R-EPOCH Chemotherapy for the Management of Acquired Immunodeficiency Syndrome (AIDS)-Related Lymphoma
Brief Summary: No standard regimen currently exists for the treatment of AIDS-related lymphoma. Based on the encouraging NCI results with DA-EPOCH, the US AIDS Malignancy Consortium is currently administering a phase II randomized protocol comparing EPOCH with sequential versus concurrent rituximab (AMC protocol 034). In this AMC trial, the decision to co-administer cART is left to the discretion of the treating physician and the patient. While the AMC phase II study may establish an acceptable chemotherapy regimen suitable for further study in a phase III randomized trial, the results will not address adherence, pharmacokinetic interactions or the role of cART in AIDS-related lymphoma. The contribution of cART to the anti-lymphoma efficacy of any regimen needs to be formally studied. Our proposed trial to demonstrate the feasibility of co-administering cART with chemotherapy would justify the use of combined therapy in future AMC/International phase III protocols.
Detailed Summary:
Study Design & Duration This is a prospective, single-arm, multi-centre, phase II trial of immuno-chemotherapy (rituximab and EPOCH) with mandatory combination antiretroviral therapy for initial treatment of AIDS-related lymphoma. Patients diagnosed with previously-untreated AIDS-related diffuse large B-cell lymphoma will be eligible for this trial. Patients are eligible regardless of whether they have previously been treated with or are naïve to antiretroviral therapy. The total sample size of 18 patients is required to determine the feasibility of co-administering cART and chemotherapy as measured by adequate adherence to the antiretroviral regimen.
Patients will receive EPOCH and rituximab chemotherapy for 6 cycles each given every 21 days. Day 1 of each cycle will consist of an infusion of rituximab followed by the initiation of a 96-hour continuous infusion of etoposide, doxorubicin, and vincristine and oral prednisone. Cyclophosphamide will be administered on Day 5 with initial dose based on initial CD4+ cell count to minimize hematologic toxicity.
Combination antiretroviral therapy will be administered to all patients enrolled in the trial. Patients already responding to their current cART regimen will continue with the same therapy. Otherwise, patients can be initiated on a preferred regimen of tenofovir (TDF), emtricitabine (FTC), and efavirenz (EFV) according to the US Department of Health and Human Services (DHHS) guidelines. Patients initiated on the preferred regimen of TDF/FTC/EFV will start the antiretroviral treatments on Day 7 of the trial, after the first cycle of R-EPOCH is administered. Treatment will subsequently be continued for the duration of the trial and thereafter, according to the discretion of the treating physician.

Current Primary Outcome: The primary outcome for this feasibility study will be medication adherence. Acceptable adherence, defined as compliance to ≥90% of all prescribed doses of cART during the course of chemotherapy, will be measured by pill counting and patient self-report [ Time Frame: 4 -6 weeks after 6 cycles of R-EPOCH ]
Original Primary Outcome: Same as current
Current Secondary Outcome: Toxicity Lymphoma response Rate Progression -free Survival and Overall Survival Pharmacokinetics [ Time Frame: 2 years post completion ]
Original Secondary Outcome: Same as current
