A Phase I Trial of Combined Chemotherapy and Donor Lymphocyte Infusion for Aggressive Hematologic Malignancies in Relapse After Allogeneic Bone Marrow Transplantation

OBJECTIVES:

• Determine the maximum tolerated dose of doxorubicin HCl liposome when combined with etoposide, cyclophosphamide, and allogeneic donor lymphocyte infusion with or without interleukin-2 after allogeneic bone marrow transplantation in patients with relapsed or persistent aggressive hematologic malignancies.

OUTLINE: This is a partially randomized, dose-escalation study of doxorubicin HCl liposome (LipoDox).

Patients enter 1 of 4 cohorts.

• Cohort 1: Three to six patients receive induction comprising etoposide IV over 1 hour on days 1-3, cyclophosphamide IV over 1-2 hours on day 8, and allogeneic donor lymphocyte infusion on day 10. Filgrastim (G-CSF) is administered subcutaneously (SC) or IV daily beginning on day 10 and continuing until blood counts recover.
• Cohort 2: In the absence of dose-limiting toxicity (DLT) on cohort 1, 3-6 patients receive treatment as in cohort 1 and LipoDox IV over 2 hours on day 1.
• Cohort 3: In the absence of DLT on cohort 2, 3-6 patients are randomized to 1 of 2 treatment arms.
