This phase I trial studies the side effects and best dose of talazoparib and heat shock protein (HSP)90 inhibitor AT13387 when given together in treating patients with solid tumors that have spread to other places in the body (metastatic) or ovarian, fallopian tube, primary peritoneal, or hormone negative breast cancer that have come back after a period of improvement (recurrent). Talazoparib and HSp90 inhibitor AT13387 may stop the growth of tumor cells by blocking some enzymes that are need for cell growth. HSp90 inhibitor AT1338 may also help talazoparib work better by making tumor cells more sensitive to the drug.
PRIMARY OBJECTIVES: I. To establish the maximum tolerated dose (MTDs) of BMN673 (talazoparib) and AT13387 (HSP90 Inhibitor AT13387) administered in combination in patients with advanced solid tumors. SECONDARY OBJECTIVES: I. To identify the dose-limiting toxicity (DLT) and other toxicities associated with BMN673 and AT13387 administered in combination as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v) 4.0. II. To determine the recommended phase 2 doses (RP2D) of the combination of BMN673 and AT13387. III. To determine the plasma pharmacokinetics of BMN673 and AT13387. IV. To document anti-tumor activity of the combination of BMN673 and AT13387 as assessed by (Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and progression free survival (PFS). OUTLINE: This is a dose-escalation study. Patients receive talazoparib orally (PO) once daily (QD) on days 1-7 (course 0). Beginning in course 1, patients receive talazoparib PO QD on days 1-28 and HSP90 inhibitor AT13387 intravenously (IV) over 1 hour on days 1, 2, 8, 9, 15, and 16. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 30 days and then every 3 months for up to 2 years.

MTD based on the dose-limiting toxicity based on the National Cancer Institute (NCI) CTCAE v. 4.0
DLT defined as non-hematologic and hematologic toxicities experienced during course 0 and the first course (i.e. first 4 weeks) of treatment.
Time frame: 35 days
Incidence of adverse events as assessed by NCI CTCAE v. 4.0
Time frame: 30 days post-treatment
Pharmacokinetic (PK) parameters of talazoparib and HSP90 inhibitor AT13387
Pearson correlation coefficients, presented with 95% confidence intervals, will be used to investigate the association of the percent change heat shock protein 90 and poly(adenosine diphosphate-ribose) polymerase 1 activities with PK parameters, including maximum concentration observed and area under the curve.
Time frame: Baseline, at 1, 2, 4 and 8 hours of day 1 (course 0), baseline of days 1, 8, and 15 of course 1, and at 1, 2, 4, and 8 hours post-dosing on day 8 and 15 of course 1
