NCT04207190

Brief Summary

This phase I/Ib trial studies the side effects and best dose of talazoparib given together with gemtuzumab ozogamicin and to see how well they work in treating patients with CD33 positive acute myeloid leukemia that has come back (relapsed) or does not respond to treatment (refractory). Talazoparib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Gemtuzumab ozogamicin is a protein (antibody) combined with a chemotherapy drug which specifically targets acute myeloid leukemia cells expressing a marker (CD33). Adding talazoparib to the gemtuzumab ozogamicin therapy may lead to an increased effectiveness in treatment.

Outcome Measures

Primary Outcomes (2)

  • Maximum tolerated dose

    Will identify the maximum tolerated dose of talazoparib in combination with gemtuzumab ozogamicin. The maximum dose level where 1 or fewer dose limiting toxicities (DLTs) are observed in 6 patients will be defined as the recommended phase 2 dose.

    Up to 28 days

  • Overall response rate (ORR)

    ORR will consist of complete remission (CR), complete remission with incomplete hematologic recovery (CRi) of combination therapy with talazoparib and gemtuzumab ozogamicin. Will be estimated by a 90% confidence interval obtained by Jeffrey's prior method.

    Up to 12 months post treatment

Secondary Outcomes (8)

  • Complete remission rate

    Up to 12 months post treatment

  • Best response rate

    Up to 12 months post treatment

  • Duration of remission

    Up to 12 months post treatment

  • Leukemia-free survival (LFS)

    Up to 12 months post treatment

  • Transfusion independence rate

    Up to 12 months post treatment

  • +3 more secondary outcomes

Study Arms (1)

Treatment (talazoparib, gemtuzumab ozogamicin)

EXPERIMENTAL

Patients receive talazoparib PO daily on days 1-21 and gemtuzumab ozogamicin IV over 2 hours on days 1, 4, and 7 or day 1 for patients who CR/CRi after cycles 1 or 2. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Eastern Cooperative Oncology Group performance status between 0-1
  • Creatinine =\< 1.5 x upper limit of normal (ULN) or calculated creatinine clearance (Cockcroft and Gault ) \> 30 mL/min (performed on plasma unless otherwise indicated)
  • Alanine aminotransferase (ALT) =\< 2.5 x ULN (performed on plasma unless otherwise indicated)
  • Direct bilirubin \< 1.5 mg/dL (performed on plasma unless otherwise indicated)
  • Left ventricular ejection fraction (LVEF) \>= 40% as assessed by echocardiogram (ECHO) or multiple-gated acquisition (MUGA) scan performed within 28 days of enrollment
  • Diagnosis of CD33+ acute myeloid leukemia (AML) with evidence of \>= 5% myeloblasts in the bone marrow, peripheral blood, or in an extramedullary site by pathology. Any CD33 receptor expression level \> 0.01% by institute flow cytometric analysis will suffice
  • Relapsed or refractory disease, defined as:
  • Any bone marrow relapse after allogeneic HSCT: subjects must be at least 1 month from HSCT at the time of screening and off immunosuppressive medication for at least 2 weeks at time of initial treatment (with the exception of low-dose steroids =\< 20 mg prednisone equivalent) and have no active graft versus (vs.) host disease (GVHD)
