Phase I/II Study of the Combination of Inotuzumab Ozogamycin (CMC-544) With Low-Intensity Chemotherapy in Patients With Acute Lymphoblastic Leukemia (ALL)
M.D. Anderson Cancer Center
Summary
This phase I/II trial studies the side effects and best dose of inotuzumab ozogamicin and to see how well it works when given together with combination chemotherapy in treating patients with acute lymphoblastic leukemia. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a toxic agent called N-acetyl-gamma-calicheamicin dimethyl hydrazide (CalichDMH). Inotuzumab attaches to CD22 positive cancer cells in a targeted way and delivers CalichDMH to kill them. Immunotherapy with monoclonal antibodies, such as blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving inotuzumab ozogamicin together with combination chemotherapy may be a better treatment for acute lymphoblastic leukemia.
Description
PRIMARY OBJECTIVES: I. Determine the maximum tolerated dose (MTD) of inotuzumab ozogamicin (inotuzumab ozogamycin) in combination with low-intensity chemotherapy in elderly patients (age 60 or older) with acute lymphoblastic leukemia (ALL). (Phase I) II. Evaluate the efficacy of inotuzumab ozogamycin in combination with low-intensity chemotherapy in elderly and unfit to receive intensive therapy patients with ALL. (Phase II) III. To evaluate the side effects of the treatment. (Phase II) IV. Evaluate the regimen efficacy in refractory-relapsed ALL. (Phase II) EXPLORATORY OBJECTIVES: I. To…
