This trial is testing how safe and effective a new oral targeted therapy (Ponatinib) is when combined with chemotherapy in the treatment of children, adolescents and young adults diagnosed with Acute Lymphoblastic LeukemiaA Pivotal Phase 1/2, Single-Arm, Open-label Study to Evaluate the Safety and Efficacy of Ponatinib With Chemotherapy in Pediatric Patients With Philadelphia Chromosome-Positive (Ph+) Acute Lymphoblastic Leukemia (ALL) Who Have Relapsed or Are Resistant or Intolerant to a Prior Tyrosine Kinase Inhibitor-Containing Therapy, or Who Have the T315I Mutation

Clinical summary

Summary

Eligible patients will asked to take ponatinib once daily. In phase 1 ponatinib will be administered in combination with chemotherapy to determine the recommended phase 2 dose (RP2D) of ponatinib. In both phase 1 and phase 2, treatment consists of two 35-day blocks of therapy (reinduction block and consolidation block). Each block will include 29 days of treatment of daily ponatinib and chemotherapy, followed by a rest period from chemotherapy for a minimum of 6 days, during which time patients will receive daily ponatinib only.

Scientific Title

A Pivotal Phase 1/2, Single-Arm, Open-label Study to Evaluate the Safety and Efficacy of Ponatinib With Chemotherapy in Pediatric Patients With Philadelphia Chromosome-Positive (Ph+) Acute Lymphoblastic Leukemia (ALL) Who Have Relapsed or Are Resistant or Intolerant to a Prior Tyrosine Kinase Inhibitor-Containing Therapy, or Who Have the T315I Mutation

Eligibility

Inclusion

  1. Participants must have a diagnosis of Ph+ ALL, Philadelphia chromosome-positive plus mixed phenotype acute leukemia (Ph+ MPAL), or Ph-like ALL with:

    a) Involvement of BM with ALL, including one of the following: i. M2 BM (5%-24% lymphoblasts): by morphology with confirmatory testing consisting of at least one of the following: flow cytometry lymphoblasts ≥5%, or BCR-ABL1 fluorescence in situ hybridization, or ≥10-2 leukemic clone identified by immunoglobulin heavy chain-T-cell receptor polymerase chain reaction, OR ii. M3 BM (≥25% lymphoblasts): by morphology, OR iii. Participants with combined BM (as defined above) and extramedullary disease.

    b) Evidence of Ph+ ALL, MPAL, or Ph-like ALL: i. Definite evidence of BCR-ABL1 fusion (Ph) for Ph+ ALL and MPAL, OR ii. Definite evidence of Ph-like ALL with targetable kinase-activating lesions involving any of the following kinase genes: ABL1, ABL2, CSF1R, and PDGFRB.

    Ph-like ALL diagnosis requires the identification of specified targetable kinase-activating lesions preferably by ribonucleic acid (RNA) sequencing or by alternative accredited method used by the site.

    c) Disease status: (i) For non-US sites: participants who have relapsed (post 0 or 1 HSCT) or are resistant or intolerant to at least one prior therapy that contained a BCR-ABL-targeted tyrosine kinase inhibitor (TKI), or for US sites: participants who have relapsed (post 0 or 1 HSCT) or are resistant or intolerant to at least one prior therapy that contained a second-generation BCR-ABL1-targeted TKI (i.e, dasatinib, nilotinib, and bosutinib); OR (ii) Have a BCR-ABL1 T315I mutation irrespective of relapse, resistance/intolerance, or transplant status and irrespective of any prior TKI use.

    Notes:

    A participant will be defined as intolerant if they had a Grade ≥3 nonhematologic toxicity or a Grade 4 hematologic toxicity considered related to the last TKI and lasting for >2 weeks, and led to discontinuation of therapy.

  2. Weight: Participants must be weighing at least 5 kg at the time of enrollment.
  3. Performance Status: Karnofsky performance status ≥50% for participants ≥16 years of age or Lansky Play Scale ≥50% for participants <16 years of age.
  4. Have recovered to less than Grade 2 National Cancer Institute common terminology criteria for adverse events (NCI CTCAE) Version 5.0, or to baseline, from any nonhematologic toxicities (except alopecia) due to previous therapy.
  5. Participants must meet the following criteria related to prior therapies:

    • Cytoreduction with hydroxyurea: Hydroxyurea can be initiated and continued for up to 24 hours before the start of protocol therapy.
    • Participants who relapsed while receiving cytotoxic therapy: At least 14 days must have passed since the completion of the last dose of chemotherapy before the first dose of ponatinib can be given except for the following: intrathecal (IT) chemotherapy and/or maintenance therapy such as vincristine, mercaptopurine, methotrexate, or glucocorticoids. There is no waiting period for those relapsing on maintenance-like therapy.
    • HSCT: Participants who have experienced relapse after a HSCT are eligible, provided they have no evidence of acute or chronic graft-versus-host disease (GVHD), are not receiving GVHD prophylaxis or treatment, and are at least 90 days posttransplant at the time of enrollment.
    • Hematopoietic growth factors: Before the first dose of ponatinib, at least 7 days must have passed since completion of therapy with granulocyte colony-stimulating factor or other growth factors, and at least 14 days must have passed since completion of therapy with pegfilgrastim.
    • Biologics and targeted therapies: Before the first dose of ponatinib, at least 7 days must have passed since the last dose of a biologic agent. For agents that have known AEs occurring beyond 7 days after administration, this period must be extended beyond the time during which AEs are known to occur. The duration of this interval must be discussed with the sponsor's medical monitor/designee.
    • Monoclonal antibodies: After the last dose of monoclonal antibody, at least 3 half-lives of the administered antibody must have passed before the first dose of ponatinib.
    • Immunotherapy: Before the first dose of ponatinib, at least 30 days must have passed after the completion of any type of immunotherapy (eg, tumor vaccines, chimeric antigen receptor T-cell [CAR-T-cell]).
    • Immunosuppressive therapy: Before the first dose of ponatinib, at least 14 days must have passed after the completion of immunosuppressive therapy (including regimens following stem cell transplant).
