S1312, Inotuzumab Ozogamicin and Combination Chemotherapy in Treating Patients With Relapsed or Refractory Acute Leukemia
S1312, Inotuzumab Ozogamicin and Combination Chemotherapy in Treating Patients With Relapsed or Refractory Acute Leukemia
This phase I trial studies the side effects and best dose of inotuzumab ozogamicin when given
 together with combination chemotherapy in treating patients with relapsed or refractory acute
 leukemia. Immunotoxins, such as inotuzumab ozogamicin, can find cancer cells that express
 cluster of differentiation (CD)22 and kill them without harming normal cells. Drugs used in
 chemotherapy, such as cyclophosphamide, vincristine sulfate, and prednisone, work in
 different ways to stop the growth of cancer cells, either by killing the cells or by stopping
 them from dividing. Giving inotuzumab ozogamicin together with combination chemotherapy may
 kill more cancer cells.
PRIMARY OBJECTIVES:

 I. To assess the safety of inotuzumab ozogamicin in combination with cyclophosphamide,
 vincristine (vincristine sulfate) and prednisone (CVP) and to determine the maximum tolerated
 dose (MTD) of inotuzumab ozogamicin in this regimen for patients with relapsed or refractory
 CD22+ acute leukemia (B-cell acute lymphoblastic leukemia [B-ALL], mixed phenotype, and
 Burkitt's).

 SECONDARY OBJECTIVES:

 I. To estimate the preliminary activity (response rate: complete remission [CR] + complete
 remission with incomplete count recovery [CRi]) of this combination in the expansion cohort.

 II. To estimate the frequency and severity of toxicities of this combination in this patient
 population.

 OUTLINE: This is a dose-escalation study of inotuzumab ozogamicin.

 Patients receive cyclophosphamide intravenously (IV) on day 1, vincristine sulfate IV on day
 1, prednisone orally (PO) on days 1-5, and inotuzumab ozogamicin IV over 1 hour on days 1, 8,
 and 15. Treatment repeats every 28 days for up to 6 courses in the absence of disease
 progression or unacceptable toxicity.

 After completion of study treatment, patients are followed up every 2 months for 1 year,
 every 3 months for 1 year, and then every 6 months for 1 year.

 leukemia, must have a lumbar puncture which is negative for CNS involvement of acute
 leukemia; the lumbar puncture must be completed within 14 days prior to registration;
 patients with no previous history of documented CNS involvement and with no clinical
