Breast Cancer Clinical Trial
Measuring the Effects of Talazoparib in Patients With Advanced Cancer and DNA Repair Variations
This phase II trial studies if talazoparib works in patients with cancer that has spread to other places in the body (advanced) and has mutation(s) in deoxyribonucleic acid (DNA) damage response genes who have or have not already been treated with another PARP inhibitor. Talazoparib is an inhibitor of PARP, a protein that helps repair damaged DNA. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. All patients who take part on this study must have a gene aberration that changes how their tumors are able to repair DNA. This trial may help scientists learn whether some patients might benefit from taking different PARP inhibitors "one after the other" and learn how talazoparib works in treating patients with advanced cancer who have aberration in DNA repair genes.
I. Determine the pharmacodynamic (PD) effect of talazoparib in tumor biopsies for patients with aberrations in deoxyribonucleic acid (DNA) damage response genes who have or have not received prior PARP inhibitor treatment (separately).
I. Determine the response rate (complete response [CR] + partial response [PR]) of treatment with talazoparib in patients with aberrations in DNA damage response genes.
I. Investigate tumor genomic alterations potentially associated with sensitivity or acquired resistance to talazoparib.
Patients receive talazoparib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo biopsy at baseline and 4 hours after talazoparib dose on day 1 of cycle 2, and an optional biopsy either at the restaging follow up or at the time of disease progression.
After completion of study treatment, patients are followed up at 30 days.
Adult patients with solid tumors and documented germline or somatic aberrations in genes involved in DNA damage response (DDR) and whose disease has progressed following at least one standard therapy or who have no acceptable standard treatment options. Molecular testing performed at an National Cancer Institute-Molecular Analysis for Therapy Choice (NCI-MATCH) (NCT02465060) study-designated Clinical Laboratory Improvement Act (CLIA) laboratory or at Myriad Genetics, GeneDx, Invitae, or the Frederick National Laboratory for Cancer Research (FNLCR) Molecular Characterization Laboratory (MoCha) will be acceptable for determination of eligibility
Patients with the following germline or somatic genetic aberrations will be eligible based on compelling preclinical and/or clinical data suggesting that these deleterious mutations confer sensitivity to PARP inhibitors; no more than 6 patients (across both cohorts) with an eligibility mutation in any one gene will be enrolled

Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >= 20 mm (>= 2 cm) by chest x-ray or as >= 10 mm (>= 1 cm) with computed tomography (CT) scan, magnetic resonance imaging (MRI), or calipers by clinical exam
Patients must have a tumor site amenable to biopsy. If avoidable, the lesion for biopsy should not be selected as a target lesion for RECIST measurements
The effects of talazoparib on the developing human fetus are unknown. For this reason and because PARP inhibitors are known to be teratogenic, women of child-bearing potential must agree to use a highly effective method of contraception for the duration of study participation and for at least 7 months after completing study treatment. 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. Male patients with female partners of reproductive potential and pregnant partners who are treated or enrolled on this protocol must also agree to use adequate contraception for the duration of study participation and for at least 4 months after completion of talazoparib administration
