Inotuzumab Ozogamicin and Blinatumomab With or Without Ponatinib in Treating Patients With Newly Diagnosed, Recurrent, or Refractory CD22-Positive B-Lineage Acute Lymphoblastic Leukemia

What this study is about

This phase II trial studies how well inotuzumab ozogamicin and blinatumomab with or without ponatinib work in treating patients with CD22-positive B-lineage acute lymphoblastic leukemia that is newly diagnosed, has come back after a period of improvement (recurrent), or does not respond to treatment (refractory).

View original scientific description

This phase II trial studies how well inotuzumab ozogamicin and blinatumomab with or without ponatinib work in treating patients with CD22-positive B-lineage acute lymphoblastic leukemia that is newly diagnosed, has come back after a period of improvement (recurrent), or does not respond to treatment (refractory). Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a chemotherapy drug, called ozogamicin. Inotuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD22 receptors, and delivers ozogamicin to kill them. Blinatumomab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Ponatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving inotuzumab ozogamicin and blinatumomab with or without ponatinib may be effective in treating patients with newly diagnosed, recurrent or refractory CD22 positive B-lineage acute lymphoblastic leukemia.

Who can participate

This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Inclusion 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.
  • 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.
  • STEP 1: CD22-positive disease defined as CD22 expression by \>= 20% of lymphoblasts by local hematopathology evaluation.
  • STEP 1: Philadelphia chromosome/BCR-ABL1-negative or Philadelphia chromosome/BCR-ABL1-positive B-cell ALL by cytogenetics, fluorescence in situ hybridization (FISH), and/or polymerase chain reaction (PCR).
  • STEP 1: 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 criteria

  • 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).

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)
  • STEP 1: 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.

Frequently asked questions

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
