Combined Modality Radioimmunotherapy For Non-Hodgkin's Lymphoma With Three Cycles Of 90Y-DOTA-peptide-Lym-1, Paclitaxel and Cyclosporin A

OBJECTIVES:

• Determine the maximum tolerated dose of yttrium Y 90 monoclonal antibody Lym-1 in combination with paclitaxel and cyclosporine in patients with recurrent or refractory non-Hodgkin's lymphoma.

OUTLINE: This is a dose-escalation study of yttrium Y 90 monoclonal antibody Lym-1 (Y90 MOAB Lym-1).

Patients receive oral cyclosporine every 12 hours on days -2 to 14. Patients receive unlabeled MOAB Lym-1 IV followed by a tracer dose of indium In 111 MOAB Lym-1 IV on day 0. On day 7, patients receive unlabeled MOAB Lym-1 IV followed by Y90 MOAB Lym-1 IV. Patients in cohorts 2-4 also receive paclitaxel IV over 3 hours on day 9. Courses repeat every 8 weeks for a total of 3 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3 patients receive escalating doses of Y90 MOAB Lym-1 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 patients experience dose-limiting toxicity.
