Talazoparib and Gemtuzumab Ozogamicin for the Treatment of CD33 Positive Relapsed or Refractory Acute Myeloid Leukemia

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

Leukemia-free survival (LFS)
Up to 12 months post treatment
Transfusion independence rate

Study Arms (1)
Treatment (talazoparib, gemtuzumab ozogamicin)
EXPERIMENTALPatients 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
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)
- AML with no prior CR/CRi after at least 1 prior cycle of remission induction chemotherapy (i.e. cytarabine or hypomethylating based regimen(s) allowed)
- AML recurring after prior CR/CRi, which was achieved following at least one prior chemotherapy cycle (i.e. cytarabine or hypomethylating based regimen(s) allowed)
- Peripheral white blood cell (WBC) counts \<25,000/mcL. Patients are allowed to receive hydroxyurea and/or leukapheresis to control and maintain WBC count prior to enrollment and can continue on hydroxyurea through Cycle 1 Day 28 or until first disease assessment
- Participants of childbearing potential must agree to use adequate contraceptive methods (e.g., hormonal or barrier method of birth control; abstinence) prior to study entry. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
- Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure
You may not qualify if:
- Acute promyelocytic leukemia (APL, FAB M3) with t(15-17) and/or evidence of promyelocytic leukemia/retinoic acid receptor alpha (PML-RAR alpha)
- Blast phase of prior chronic phase chronic myeloid leukemia with t(9;22)
- Receipt of chemotherapy (except for hydroxyurea), radiotherapy, or investigational drug therapy within 2 weeks prior to treatment on study or those who have not recovered from adverse events due to agents administered \> 2 weeks earlier
- Known active central nervous system involvement; patients who have a history of central nervous system (CNS) disease which has been effectively treated as defined by at least one negative cerebrospinal sample prior to screening are eligible
- Active uncontrolled malignancy requiring ongoing chemotherapy and/or radiation. Examples of eligible patients include individuals with a prior history of malignancy treated with curative intent with no current evidence of active disease such as:
- Subjects with stage I breast cancer that has been completely and successfully treated, requiring no therapy or only anti-hormonal therapy
- Subjects with T1N0M0 or T2N0M0 colorectal cancer who have been completely and successfully resected and who are disease-free for \> 2 years prior to screening
- Subjects with indolent prostate cancer, defined as clinical stage T1 or T2a, Gleason score =\< 6, and prostate specific antigen (PSA) \< 10 ng/mL, requiring no therapy or only anti-hormonal therapy
- Subjects with a history of basal cell or squamous cell carcinoma of the skin, or carcinoma in situ of the cervix, fully resected, and with no evidence of active disease
- Other prior or concurrent malignancies will be considered on a case-by-case basis after discussion with the principal investigator (PI)
- Uncontrolled current medical illness including, but not limited to:
- Severe cardiac disorder (symptomatic congestive heart failure requiring treatment, chronic unstable angina pectoris, myocardial infarction, cardiac arrhythmia, torsades de pointes,
- Neurologic impairment (cerebrovascular accident, transient ischemic attack)
- Severe pulmonary disorder (e.g. DLCO of 65% or less or a forced expiratory volume in 1 second \[FEV1\]) of 65% of less)
- Moderate hepatic impairment with total bilirubin \>1.5 x upper limit of normal (ULN),
