简要总结
RATIONALE: The CAT-8015 immunotoxin can bind tumor cells and kill them without harming normal cells. This may be an effective treatment for hairy cell leukemia(HCL) that has not responded to chemotherapy, surgery or radiation therapy.
PURPOSE: Phase I dose escalation study to determine the maximum tolerated dose of CAT-8015 immunotoxin in treating patients who have hairy cell leukemia (HCL) that has not responded to treatment.
详细描述
OUTLINE: Patients receive CAT-8015 IV over 30 minutes on days 1, 3, and 5 followed by rest. Treatment repeats every 4 weeks for up to a total of 10 courses in the absence of dose limiting toxicity, complete response or disease progression. Patients are followed at 1, 3, 6,12,15,18, 21, 24 months following the start of the last treatment cycle.
Cohorts of 3-6 patients each will receive escalating doses of recombinant CAT-8015 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose proceeding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, between16 to 25 new patients will be added to the MTD cohort depending on how well the CAT-8015 is tolerated.
