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

Purpose

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.

Conditions

  • B Acute Lymphoblastic Leukemia, Philadelphia Chromosome Negative
  • Recurrent B Acute Lymphoblastic Leukemia

Criteria

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.

- 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.

- Eastern Cooperative Oncology Group (ECOG) performance status: 0-2

- No unstable cardiac disease such as myocardial infarction, angina pectoris,
uncontrolled heart failure, or uncontrolled cardiac arrhythmia within 6 months of
registration.

- No impaired cardiac function, defined as left ventricular ejection fraction (LVEF) <
45% or New York Heart Association (NYHA) stage III or IV congestive heart failure
(CHF).

basal- or squamous-cell skin cancer, in situ cervical cancer, stage I or II cancer
from which the patient is currently in complete remission, or any other cancer from
which the patient has been disease-free for >= 2 years.

- No history of clinically significant ventricular arrhythmia, unexplained
non-vasovagal syncope, or chronic bradycardic states such as sinoatrial block or
higher degree of atrioventricular block unless a permanent pacemaker has been
implanted.
