OUTLINE: Patients receive initial cell dose of donor lymphocytes (CD3+ cells) IV over 15-30 minutes. Patients with rapidly progressive disease may skip the initial cell dose and proceed directly to dose escalation to receive CD3+ cells at a higher cell dose. Patients who achieve complete response to the initial treatment may receive up to 2 additional courses of escalating doses of CD3+ cells 8-12 weeks apart in the absence of unacceptable toxicity. Patients are evaluated at 4 and 8 weeks after each infusion. Patients with disease progression at 8 weeks are retreated at that time. Patients who achieve partial response or stable disease at 8 weeks are re-evaluated at 12 weeks and may then be retreated.
