Bortezomib and Antiviral Therapy Followed By Effusion Drainage, Bevacizumab, and Combination Chemotherapy in Treating Patients With Primary Effusion Lymphoma

OBJECTIVES:

Primary

* Determine the complete response rate in patients with previously untreated primary effusion lymphoma treated with effusion drainage and bevacizumab in combination with chemotherapy comprising cyclophosphamide, doxorubicin, and etoposide.

Secondary

* Determine the overall survival, disease-free survival, and progression-free survival of patients treated with this regimen. * Determine the toxicity of this regimen in previously treated or untreated patients. * Determine, preliminarily, the biologic effects of targeted oncolytic virotherapy comprising bortezomib, zidovudine, and valganciclovir in these patients.

OUTLINE: This is a 2-part, pilot study.

Patients who are HIV-positive receive highly-active antiretroviral therapy during study treatment.

* Part 1 (targeted oncolytic virotherapy)\*: Patients receive bortezomib IV over 3-5 seconds on days 1, 4, and 8, zidovudine IV over 1 hour twice daily on days 1-10, and oral valganciclovir (or ganciclovir IV) twice daily on days 1-14. One day after completion of zidovudine, patients begin treatment in part 2.

NOTE: \*Part 1 treatment may be omitted in patients who are acutely ill with primary effusion lymphoma at study entry AND a 10- to 14-day delay of starting part 2 treatment may pose a hazard to the patient.

* Part 2

* Effusion drainage: Patients undergo effusion drainage prior to each course of bevacizumab\* and chemotherapy. The drainage tube may remain in place to allow for continuous drainage of effusion during treatment with bevacizumab\* and chemotherapy. * Bevacizumab\* plus cyclophosphamide, doxorubicin, and etoposide (iCDE): Patients receive bevacizumab\* IV over 30-90 minutes on days 1 and 6, cyclophosphamide, doxorubicin, and etoposide IV continuously over 96 hours beginning on day 1 and continuing until day 5, and filgrastim (G-CSF) subcutaneously (SC) daily beginning on day 6 and continuing until day 19 or until blood counts recover OR pegfilgrastim SC on day 6.

NOTE: \*Patients may receive iCDE without bevacizumab if they meet any exclusion criteria for receiving bevacizumab.

Treatment with bevacizumab and iCDE repeats every 21 days for 4-8 courses in the absence of disease progression or unacceptable toxicity. Patients achieving complete response (CR) receive 2 additional courses beyond CR.

After completion of study treatment, patients are followed monthly for 6 months, every 2 months for 6 months, every 3 months for 1 year, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 15 patients will be accrued for this study within 2.5 years.
