Inotuzumab Ozogamicin and Blinatumomab in Treating Patients With Newly Diagnosed, Recurrent, or Refractory CD22-Positive B-Lineage Acute Lymphoblastic Leukemia

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.

Stanford is currently not accepting patients for this trial.

Phase 2


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

         - 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.

      - This study involves agents that have known genotoxic, mutagenic, and teratogenic
      effects. Therefore, for women of childbearing potential only, a negative
      pregnancy test done =< 7 days prior to registration is required.
