About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
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.
ECOG performance status ≥ 2
Severe cardiac disorder (e.g., congestive heart failure requiring treatment, ejection fraction ≤ 50%, or chronic stable angina)
Disqualifiers
Newly diagnosed Burkitt's Leukemia or Lymphoma, T-cell ALL or lymphoblastic lymphoma.
Patient with active heart disease (NYHA class > 3 as assessed by history and physical examination).
Patients with a cardiac ejection fraction (as measured by either MUGA or echocardiogram) < 40% are excluded.
Patients with active hepatitis are excluded.

Trial outcomes
Primary outcomes
Maximum tolerated dose of inotuzumab ozogamicin based on incidence of dose limiting toxicities (Phase I)
Defined as non-hematologic grade 3 or 4 toxicities during the first course. Toxicities will be monitored using the method of Thall, Simon, and Estey. Adverse events will be summarized and toxicity rate will be estimated with a 90% credible interval.
Progression free survival (PFS) in frontline elderly acute lymphoblastic leukemia (ALL) (Phase II)
Bayesian time-to-event model will be used. Kaplan and Meier product limit method will be used to estimate the PFS along with the 95% confidence intervals for the median PFS. Univariate and multivariate Cox proportional hazards regression models will be used to identify prognostic factors.
Response rate in refractory-relapsed acute lymphoblastic leukemia (ALL) (Phase II)
The precise complete remission (CR) and marrow CR rate will be defined.
Survival in refractory-relapsed acute lymphoblastic leukemia (ALL) (Phase II)
The median and 1-year survival rate will be defined. Kaplan and Meier product limit method will be used to estimate the overall survival (OS) along with the 95% confidence intervals for the median OS. Univariate and multivariate Cox proportional hazards regression models will be used to identify prognostic factors.
