Detailed Description
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.
The primary endpoint for this feasibility study will be medication adherence to cART treatment. "Acceptable adherence" will be defined as the proportion of patients able to complete >90% of all prescribed cART doses during the course of chemotherapy as measured by pill counts. As previously reported, study participants will be asked to bring their pill bottles to clinic prior to each chemotherapy cycle (every three weeks) so that remaining pills can be counted by the participating study nurse/pharmacist. The number of missed doses will be computed from the difference between the actual and expected number of pills remaining in the bottle. Secondary outcomes include the toxicity of the combination therapy, as measured by adverse events graded according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0. CD4+ cell counts and HIV-1 mRNA viral loads will be obtained on all patients at baseline, following recovery from cycles 3 and 6, and every three months thereafter for two years. Secondary outcomes will also include complete and partial lymphoma response rate, progression-free survival, and overall survival, all defined by International Working Group criteria. The pharmacokinetics of etoposide, vincristine and doxorubicin will be studied in the patients initiating the preferred antiretrovirals TDF/3TC/EFV on Day 7 of the protocol (after completion of the first cycle of R-EPOCH). Thus the analysis of PK interactions will be on this subgroup of patients receiving a uniform treatment strategy. Pharmacokinetics will be assessed with the first cycle (when chemotherapy is given alone) and subsequent cycle of R-EPOCH (when chemotherapy is given with cART).
Study administration and data collection will occur under the auspices of the Ontario Clinical Oncology Group (OCOG). OCOG operates from within the Clinical Trials Methodology Group at the Henderson Research Centre in Hamilton and is co-directed by oncologists at the Juravinski Cancer Centre and Toronto Sunnybrook Cancer Centres. OCOG has a well-established research environment to guide the administration of this trial across four unique clinical sites across Canada. The clinical sites for the study include Toronto Sunnybrook Regional Cancer Centre (TSRCC), Princess Margaret Hospital (PMH), St. Michael's Hospital (SMH), and at the St. Paul's Hospital (SPH) in Vancouver. Each clinical site is expected to enroll 1-4 patients per year. An overall accrual rate of 8-10 patients per year is expected. Therefore, it will be possible to register 18 patients within 2 years of study initiation. For the individual patient, the chemotherapy treatment duration is 18 weeks. Following this phase of therapy (18 weeks), individual patients will be followed every 3 months for an additional 2 years.
