OUTLINE: This is a dose-escalation study of talazoparib. Patients are assigned to 1 of 2 dosing schedules.
SCHEDULE A: Patients receive talazoparib orally (PO) once daily (QD) on days 1-7, paclitaxel intravenously (IV) over 1 hour on days 1, 8, and 15, and carboplatin IV over 30 minutes on day 1. Treatment repeats every 21 days for 4-6 courses in the absence of disease progression or unacceptable toxicity.
SCHEDULE B: Patients receive talazoparib PO QD on days 1-3, paclitaxel IV over 1 hour on days 1, 8, and 15, and carboplatin IV over 30 minutes on day 1. Treatment repeats every 21 days for 4-6 courses in the absence of disease progression or unacceptable toxicity.
At any time after 4-6 courses of treatment, patients may continue combination study therapy with talazoparib, carboplatin, and paclitaxel, talazoparib and carboplatin, talazoparib alone (continuous dosing), or observation without therapy at the discretion of the treating physician.
After completion of study treatment, patients are followed up for 4 weeks.
- Patients must have histologically confirmed solid malignancy (excluding lymphoma) that is metastatic or unresectable and for which standard curative measures do not exist or are no longer effective, and for which: a) there is reasonable expectation of response to the combination of carboplatin/paclitaxel OR b) breast cancer (BRCA) 1/2 germline mutation is present; results from Myriad will be acceptable; if testing for BRCA 1 and 2 germline mutations is done through another organization, a report from a genetics consult with a qualified medical professional confirming that the laboratory results show a recognized germline deleterious BRCA 1 or 2 mutation or rearrangement is required; if the latter cannot be obtained, principal investigator (PI) or study chair review of the lab results and confirmation of BRCA mutation or rearrangement will be required OR c) BRCA 1/2 somatic mutation previously identified using a Clinical Laboratory Improvement Amendments (CLIA) certified assay
- Patients must have measurable or evaluable disease, as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
- Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
- Life expectancy of greater than 12 weeks
- Absolute neutrophil count >= 1,500/mcL
- Hemoglobin >= 9 g/dL
- Platelets >= 150,000/mcL
- Total bilirubin =< 1.25 x institutional upper limit of normal (ULN), with the exception of < 2.9 mg/dL for patients with Gilbert's disease
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x ULN; =< 5 x ULN in setting of metastatic liver disease
- Creatinine =< 1.5 x upper limit of normal OR creatinine clearance >= 50 mL/min
- Ability to take oral medications
- Patients with central nervous system (CNS) metastases must be stable after therapy for CNS metastases (such as surgery, radiotherapy or stereotactic radiosurgery) for at least 3 months and must be off steroid treatment for 2 weeks prior to study enrollment
- Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; 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; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of BMN 673 administration
- Ability to understand and the willingness to sign a written informed consent document
- Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) or targeted therapies within 2 weeks prior to entering the study or those who have not recovered (=< grade 1) from adverse events due to agents administered with the exception of any grade of alopecia
- No prior carboplatin unless given in neoadjuvant/adjuvant setting for curative intent and more than 6 months have elapsed since last carboplatin dose; in the case of relapsed ovarian cancer, patients are eligible if more than 6 months have elapsed since last carboplatin dose
- Patients who are receiving any other investigational agents
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to BMN 673 or other agents used in study
- Peripheral neuropathy of severity greater than grade 1
- The following medications are contraindicated or must be used with caution

- CYP3A4 sensitive substrates
- Exclusions: the following supportive care medications will be allowed: dexamethasone, aprepitant, fosaprepitant, and ondansetron; oral pain medications such as hydrocodone, oxycodone taken on an as needed basis are also permitted; transdermal products designed for systemic delivery must be assessed for interaction potential; topical products not designed to provide systemic delivery (including inhaled products, ophthalmologic products and transvaginal preparations) do not need to be considered since they do not have appreciable systemic absorption
- Other contraindicated medications (per above) are not allowed unless close monitoring with labs or drug levels with dose adjustments is feasible; patients taking these concurrent medications are ineligible unless they can discontinue or switched to alternative medications prior to initiation of the study drug (at least 5 half-lives)
- Use with caution:
- CYP2C8 sensitive substrates
- CYP2C8 weak inhibitors
- CYP3A4 non-sensitive substrates
- CYP3A4 weak inhibitors
- These agents may be permitted if discontinuation is not feasible and no acceptable alternatives are available as determined by the treating physician; however, caution should be used; consider monitoring with labs or drug levels and dose adjustments of the medication
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
