Description

Summary

This phase II trial studies how well inotuzumab ozogamicin and blinatumomab work in treating patients with CD22-positive B-lineage acute lymphoblastic leukemia that is newly diagnosed, has come back, or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as inotuzumab ozogamicin and blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Official Title

A Phase II Study of Inotuzumab Ozogamicin Followed by Blinatumomab for Ph-Negative CD22-Positive B-Lineage Acute Lymphoblastic Leukemia in Newly Diagnosed Older Adults or Adults With Relapsed or Refractory Disease

Details

PRIMARY OBJECTIVES:

  1. To confirm tolerability of the combination regimen of inotuzumab ozogamicin followed by blinatumomab.

II. To estimate the 1-year event-free survival of older, transplant-ineligible patients with newly diagnosed, Philadelphia (Ph)-negative, CD22-positive, B-cell acute lymphoblastic leukemia (ALL) treated with inotuzumab ozogamicin induction followed by blinatumomab consolidation. (Cohort 1) III. To estimate the 1-year event-free survival of patients with relapsed or refractory Ph-negative, CD22-positive, B-cell ALL treated with inotuzumab ozogamicin induction followed by blinatumomab consolidation. (Cohort 2)

SECONDARY OBJECTIVES:

  1. To estimate the median, 1-year, and 3-year overall survival (OS) in all eligible patients. (Cohort 1) II. To estimate the median, 1-year, and 3-year relapse-free survival (RFS) in all eligible patients. (Cohort 1) III. To estimate the median and 3-year event-free survival (EFS) in all eligible patients. (Cohort 1) IV. To estimate the complete response (CR) rate and overall response rate (ORR, defined as complete response [CR] + complete response with incomplete count recovery [CRi]) to inotuzumab ozogamicin followed by blinatumomab (regimen CR rate and ORR). (Cohort 1) V. To estimate the CR rate and ORR (CR + CRi) to inotuzumab ozogamicin induction alone (induction CR and ORR). (Cohort 1) VI. To estimate the minimal residual disease (MRD) negativity rate in subjects achieving a CR or CRi. (Cohort 1) VII. To estimate the treatment-related mortality with this regimen. (Cohort 1) VIII.

II. To correlate specific karyotype groups with response rates, response duration, survival, and cure in patients treated with inotuzumab ozogamicin followed by blinatumomab.

III. To correlate specific karyotype groups with MRD. IV. To determine karyotype changes at relapse and the influence of the type of change (or no change) in karyotype at relapse.

  1. To assess the correlation of quantitative MRD post-induction with inotuzumab ozogamicin and at sequential consolidation time points with blinatumomab with RFS, EFS, and OS.

VI. To correlate the influence of MRD status (detectable versus [vs.] not and as a continuous measure) in relation to EFS, RFS, and OS with other clinical and biological factors (e.g. previously untreated vs. relapsed disease cohorts; age, initial white blood cell [WBC] count, cytogenetics).

VII. To identify genetic variants and predictors of ex vivo resistance. VIII. To identify genetic variants and predictors of MRD. IX. To identify genetic variants and predictors of relapse. X.

OUTLINE: Patients are assigned to 1 of 2 cohorts.

COHORT 1: Patients receive inotuzumab ozogamicin intravenously (IV) over 1 hour on day 1, 8, and 15 (Course IA). By the end of Course IA (day 21), patients with adequate ALL cytoreduction continue to Course IB/IC, and patients who fail to achieve ALL cytoreduction continue to Course II. By the end of Course II, patients with CR-CRi to Course IB/IC and Course II continue to Course IIIA, patients without adequate ALL cytoreduction to Course IA or refractory to Course IB/IC but CR/CRi to Course II continue to Course IIIB.

COHORT 2: Patients receive inotuzumab ozogamicin IV over 1 hour on day 1, 8, and 15 (Course IA). By the end of Course IA (day 21), patients with adequate ALL cytoreduction continue to Course IB/IC, and patients who fail to achieve ALL cytoreduction continue to Course II. Patients with CR/CRi at the end of Course II continue to Course IIIB.

COURSE IB/IC: Patients receive inotuzumab ozogamicin IV over 1 hour on days 1, 8, and 15. Treatment continues for 1 course (28 days) in the absence of disease progression or unacceptable toxicity.

COURSE II: Patients receive blinatumomab IV continuously on days 1-28 and 43-70. Treatment continues for 1 course (84 days) in the absence of disease progression or unacceptable toxicity.

COURSE IIIA: Patients receive blinatumomab IV continuously on days 1-28 and 43-70. Treatment continues for 1 course (84 days) in the absence of disease progression or unacceptable toxicity.

COURSE IIIB: Patients receive blinatumomab IV continuously on days 1-28, 43-70, and 85-112. Treatment continues for 1 course (126 days) in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 3 years, and then every 6 months for up to 10 years.

Eligibility

For people ages 18 years and up

Inclusion Criteria:

  • Pre-registration Eligibility Criteria (Step 0)
  • Submission of bone marrow aspirate and peripheral blood for MRD analysis is mandatory prior to registration; the bone marrow sample should be from the first aspiration (i.e. first pull). Aspirate needle should be redirected if needed to get first pull bone marrow aspirate. It should be initiated as soon as possible after pre-registration. The specimens should be sent to the HEME Biobank.

    • Lumbar Puncture (Spinal Tap) and Intrathecal Methotrexate:

      - Patients may receive the day 1 of course IA dose of intrathecal (IT) methotrexate during the prior-to-registration lumbar puncture (or the venous line placement) to avoid a second lumbar puncture. If the dose is administered prior to registration, then systemic chemotherapy must begin within 7 days of this IT chemotherapy.

  • Registration Eligibility Criteria (Step 1)
  • Morphologic diagnosis of precursor B-cell acute lymphoblastic leukemia (ALL) based on World Health Organization (WHO) criteria. Patients with Burkitt lymphoma/leukemia are not eligible.
  • CD22-positive disease defined as CD22 expression by >= 20% of lymphoblasts by local hematopathology evaluation.
  • Philadelphia chromosome/BCR-ABL1-negative ALL by cytogenetics, fluorescence in situ hybridization (FISH), and/or polymerase chain reaction (PCR). If any test is positive for Philadelphia chromosome/BCR-ABL1, then the patient is ineligible.
  • No active central nervous system (CNS) leukemia (i.e. only CNS-1 disease allowed). Active CNS leukemia is defined as morphologic evidence of lymphoblasts in the cerebrospinal fluid (CSF), use of CNS-directed local treatment for active disease within 28 days prior to registration, symptomatic CNS leukemia (i.e. cranial nerve palsies or other significant neurological dysfunction) within the 28 days prior to registration, and/or known asymptomatic parenchymal CNS mass lesions; see below for additional guidance. Prophylactic intrathecal medication alone is not an exclusion.

    • Categories of CNS Involvement for CNS Evaluation Prior to Registration:

      - CNS 1: CSF has < 5 WBC/uL with cytospin negative for blasts; or >= 10 red blood cell (RBC)/uL with cytospin negative for blasts. - CNS 2: CSF has < 5 WBC/uL with cytospin positive for blasts; or >= 10 RBC/uL with cytospin positive for blasts; or >= 10 RBC/uL, WBC/uL >= 5 but less than Steinherz/Bleyer algorithm with cytospin positive for blasts (see below). - CNS 3: CSF has >= 5 WBC/uL with cytospin positive for blasts; or >= 10 RBC/uL, >= 5 WBC/uL and positive by Steinherz/Bleyer algorithm (see below); or clinical signs of CNS leukemia (such as facial nerve palsy, brain/eye involvement or hypothalamic syndrome). Steinherz/Bleyer Method of Evaluating Initial Traumatic Lumbar Punctures: - If the patient has leukemia cells in the peripheral blood and the lumbar puncture is traumatic and contains >= 5 WBC/uL with blasts, the following algorithm should be used to define CNS disease: CSF WBC/CSF RBC > 2 x (Blood WBC/Blood RBC count)

  • Patients with known or suspected testicular involvement by leukemia are allowed provided that the patient receives concomitant scrotal/testicular radiotherapy.
    • Unilateral or bilateral testicular enlargement should be assessed by ultrasound or other imaging technique. Biopsy is recommended if clinical findings are equivocal or suggestive of hydrocele or a non-leukemic mass, but further assessments are per treating physician discretion.
  • Not pregnant and not nursing.
