Study of the Combination of Inotuzumab Ozogamycin (CMC-544) With Low-intensity Chemotherapy in Patients With Acute Lymphoblastic Leukemia (ALL)
The goal of the Phase I part of this clinical research study is to test 2 dose levels of the drug inotuzumab ozogamycin to find the highest tolerable dose that can be given in combination with chemotherapy. The goal of Phase II is to learn if inotuzumab ozogamycin given in combination with chemotherapy can help to control acute lymphoblastic leukemia (ALL). The safety of the study drugs will also be studied.
Participants in this study are at least 60 years of age and have newly diagnosed ALL or have refractory-relapsed ALL regardless of age.
Inotuzumab ozogamycin is designed to attach to a protein that is often found in leukemia cells. This may cause the cancer cells to die.
Rituximab is designed to attach to cancer cells and damage them, which may cause the cells to die.
Hyper-CVD includes a combination of cyclophosphamide, vincristine, dexamethasone, methotrexate, Ara-C (cytarabine), and Neulasta (pegfilgrastim). The maintenance therapy used in this study is called POMP, which includes a combination of mercaptopurine, methotrexate, vincristine, and prednisone. These chemotherapy drugs are designed to interfere with the multiplication of cancer cells, which may slow or stop their growth and spread throughout the body. This may cause the cancer cells to die.
Acute Lymphoblastic Leukemia
Drug: Inotuzumab Ozogamycin
|Study Design:||Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Treatment
|Official Title:||Phase I/II Study of the Combination of Inotuzumab Ozogamycin (CMC-544) With Low-intensity Chemotherapy in Patients With Acute Lymphoblastic Leukemia (ALL)|
- Phase I: Maximum Tolerated Dose (MTD) of Inotuzumab Ozogamycin in Combination With Low-Intensity Chemotherapy [ Time Frame: With each 4 week study cycle ]
MTD defined by Dose Limiting Toxicities (DLTs) where DLTS observed in less than 2/6 participants treated at dose level 1 results in testing dose level 2 of inotuzumab ozogamycin. If DLTs are observed in < 2/6 patients treated, the second dose level is utilized for Phase II.
Dose limiting toxicities according to the NCI CTEP criteria
- Phase II: Progression-free survival (PFS) [ Time Frame: 2 years ]
Progression-free survival (PFS) was defined as the time between randomization and the date of first documented disease progression, relapse or death by any cause, whichever came first.
Bone marrow aspiration and/or biopsy (about 1 teaspoon) to check the status of the disease between Days 14-21 (+/- 3 days) of Cycle 1, and then every 2-4 cycles during consolidation.
|Actual Study Start Date:||August 2011|
|Estimated Study Completion Date:||September 2018|
|Estimated Primary Completion Date:||September 2018 (Final data collection date for primary outcome measure)|
