Brief summary

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.

Detailed description

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.

Complete remission (CR) is defined as \< 5% marrow aspirate blasts, neutrophils ≥ 1000/uL, platelets \> 100,000/uL, no blasts in peripheral blood, and C1 Extramedullary disease status.

Response Rate (CR+CRi) Among Expansion Cohort

The response rate (CR + CRi) is defined as the rate of complete remission (CR) + complete remission with incomplete count recovery (CRi). Complete remission (CR) is defined as \< 5% marrow aspirate blasts, neutrophils ≥ 1000/uL, platelets \> 100,000/uL, no blasts in peripheral blood, and C1 Extramedullary disease status. C1 Extramedullary disease status is characterized by complete disappearance of all measurable and non-measurable extramedullary disease with the exception of lesions for which the following must be true: for participants with at least one measurable lesion, all lesions must have reduced by 75% in sum of products of greatest diameters (SPD), have no new lesions, and the spleen and other previously enlarged organs must have regressed in size. Complete remission with incomplete platelet recovery (CRi) is defined the same as CR, except absolute neutrophil count may be \<1000/uL and/or platelet count may be ≤ 100,000/uL.

Time frame: Up to 3 years

Population: MTD arm only, including eligible patients who received treatment and were evaluable for response
