Inotuzumab Ozogamicin

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 identify genomic alterations in adult ALL predictive for response and long-term outcomes with the combination of hyper-CVD (cyclophosphamide, dexamethasone, methotrexate, and cytarabine) + inotuzumab + blinatumomab. II.

Giving inotuzumab ozogamicin together with combination chemotherapy may be a better treatment for acute lymphoblastic leukemia.

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.

• Patients age 60 years or older with previously untreated ALL pre-B, Philadelphia chromosome (Ph-) negative or (Ph+) positive ALL Minimal prior therapy (less than 1 week of steroids, vincristine, and/or 1 dose of anthracycline or alkylating agents) are allowed.
• Patients unfit ≥ 18 - \< 60 years of age with previously untreated ALL pre- B, Philadelphia chromosome (Ph-) negative or (Ph+) positive ALL (includes patients initiated on first cycle of hyper-CVAD before cytogenetics known. These patients could have received one or two cycles of chemotherapy with or without other TKIs and still eligible.
• These patients are defined as having at least one of the below comorbidities:
• ECOG performance status ≥ 2
• Severe cardiac disorder (e.g., congestive heart failure requiring treatment, ejection fraction ≤ 50%, or chronic stable angina)
• Severe pulmonary disorder (e.g., DLCO ≤ 65% or FEV1 ≤ 65%)
