PURPOSE: This phase I/II trial is studying the side effects and best dose of radiolabeled monoclonal antibody when given together with pentetic acid calcium and to see how well they work in treating patients with recurrent Hodgkin's lymphoma or non-Hodgkin's lymphoma.
- Assess the toxicity and therapeutic efficacy of yttrium Y 90 radiolabeled humanized anti-Tac (HAT) monoclonal antibody in patients with Tac expressing hematologic malignancies.
- Define the pharmacokinetics of indium In 111 and yttrium Y 90 HAT monoclonal antibodies.
OUTLINE: This is a dose-escalation study.
Patients are given yttrium Y 90 labeled humanized anti-Tac monoclonal antibody (Y-HAT) according to an escalating dose schedule along with a fixed dose of pentetic acid calcium (Ca-DTPA) and indium In 111 labeled humanized anti-Tac monoclonal antibody (In-HAT). On day 1, Y-HAT and In-HAT are administered IV over 2 hours followed by a 5-hour infusion of Ca-DTPA. Additional 5-hour infusions of Ca-DTPA are given on days 2 and 3. Treatment may repeat every 6 weeks for up to 7 courses.
Cohorts of 3 to 6 patients are enrolled at each dose level. Dose escalation continues until the maximum-tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 or more patients experience dose-limiting toxicity. After the MTD is defined the phase II portion of the study begins.
PROJECTED ACCRUAL: Approximately 65 patients will be accrued in phase I and an additional 30 patients in phase II.
