Talazoparib and Gemtuzumab Ozogamicin for the Treatment of CD33 Positive Relapsed or Refractory Acute Myeloid Leukemia
Phase 1/1b Trial of Talazoparib and Gemtuzumab Ozogamicin in Adult Patients With Relapsed and/or Refractory Acute Myeloid Leukemia
Study Overview
Status
Detailed Description
PRIMARY OBJECTIVES:
I. Determine the safety and tolerability of talazoparib given in combination with gemtuzumab ozogamicin therapy in adult patients with relapsed and/or refractory acute myeloid leukemia (AML).
II. Determine the overall response rate (ORR consisting of complete remission [CR] or complete remission with incomplete hematologic recovery [CRi]) of combination therapy with talazoparib and gemtuzumab ozogamicin in patients with relapsed and/or refractory AML.
SECONDARY OBJECTIVE:
I. Evaluate the preliminary anti-leukemic efficacy of talazoparib given in combination with gemtuzumab ozogamicin as determined by complete remission (CR) rate, best response rate (CRi + partial remission [PR]), duration of remission, leukemia-free survival (LFS), transfusion independence (TI), and overall survival (OS) in patients treated with this combination therapy.
EXPLORATORY OBJECTIVES:
I. Evaluate the efficacy of talazoparib given in combination with gemtuzumab ozogamicin on minimal residual disease (MRD) in treated patients.
II. Evaluate mechanistic biomarkers including levels of PARP inhibition and deoxyribonucleic acid (DNA) damage effects in peripheral blood and marrow samples from patients treated with combination therapy.
III. Evaluate quality of life (QOL) of patients with relapsed/refractory AML treated with talazoparib and gemtuzumab ozogamicin.
IV. Evaluate the number of patients able to proceed onto subsequent hematopoietic stem cell transplantation (HSCT) following combination therapy.
OUTLINE: This is a dose-escalation study of talazoparib.
Patients receive talazoparib orally (PO) daily on days 1-21 and gemtuzumab ozogamicin intravenously (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.
After completion of study treatment, patients are followed up at 30 days, then every 3 months for up to 12 months.
