Brief summary: This phase I trial studies the side effects and best dose of talazoparib in treating patients with solid tumors that have spread to other places in the body and usually cannot be cured or controlled with treatment (advanced) or have spread to other places in the body (metastatic) and cannot be removed by surgery and liver or kidney dysfunction. Talazoparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description: PRIMARY OBJECTIVES:

I. To determine safety, tolerability and recommended phase 2 dose (RP2D) of talazoparib in patients with varying degrees of hepatic and renal dysfunction.

SECONDARY OBJECTIVES:

I. To observe preliminary antitumor activity of talazoparib in patients with cancers that commonly harbor defects in homologous recombination repair.

II. To assess the pharmacokinetic (PK) profiles of talazoparib in patients with varying degrees of hepatic and renal dysfunction.

III. To evaluate the pharmacodynamic (PD) effects of talazoparib. IV. To evaluate biomarkers associated with response or resistance to talazoparib.

OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 6 cohorts based on the degree of hepatic or renal dysfunction.

Patients receive talazoparib orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 4 weeks.

Eligibility criteria: Inclusion Criteria:

* Patients must have histologically confirmed malignancy that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective
* Any advanced solid malignancy will be eligible, with a strong preference for tumors that are known to commonly harbor defects in homologous recombination repair including triple-negative breast cancer, high-grade serous ovarian cancer, non-small cell lung cancer, small cell lung cancer, mesothelioma castration-resistant prostate cancer, pancreatic adenocarcinoma, gastric cancer and head \& neck squamous cell cancer
* Measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 criteria
* All patients must have completed any prior chemotherapy, targeted therapy, radiotherapy (unless palliative doses which must be discussed with study principal investigator), and surgery, \>= 28 days before study entry
* Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (Karnofsky \>= 60%)
* Life expectancy of greater than 3 months
* Able to swallow and retain orally-administered medication and does not have any clinically significant gastrointestinal abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach or bowels

* Absolute neutrophil count \>= 1,500/mcL
* Platelets \>= 100,000/mcL
* Hemoglobin \>= 90 g/L
* Hepatic and renal function meeting the strata as outlined below; nota bene (NB): patients must fulfill both total bilirubin and serum glutamic-oxaloacetic transaminase (SGOT)/aspartate aminotransferase (AST) criteria and creatinine function to be included in a group; however, if a patient's total bilirubin and SGOT/AST and creatinine levels indicate different groups, the patient may be enrolled in the indicated group with the greatest degree of liver dysfunction; all liver and renal function tests must be completed within 24 hours prior to the start of treatment; Note: patients on dialysis will not be eligible

  * Group A: hepatic function: normal function (bilirubin =\< upper limit of normal \[ULN\]; AST =\< ULN); renal function: normal function (creatinine clearance \[CrCl\] \>= 60 mL/min)
  * Group B: hepatic function: normal function (bilirubin =\< ULN; AST =\< ULN); renal function: moderate dysfunction (CrCl \>= 30 and \< 60 ml/min)
  * Group C: hepatic function: normal function (bilirubin =\< ULN; AST =\< ULN); renal function: severe dysfunction (CrCl \>= 15 and \< 30 ml/min)
  * Group D: hepatic function: mild dysfunction D1: bilirubin =\< ULN; AST \> ULN, D2: bilirubin \> ULN and =\< 1.5 x ULN; any AST; renal function: normal function (creatinine clearance \[CrCl\] \>= 60 mL/min)
  * Group E: hepatic function: mooderate dysfunction (bilirubin 1.5 x \> ULN and =\< 3 x ULN; any AST); renal function: normal function (creatinine clearance \[CrCl\] \>= 60 mL/min)
  * Group F: hepatic function: severe dysfunction (bilirubin \> 3 x ULN and up to investigator's discretion; any AST); renal function: normal function (creatinine clearance \[CrCl\] \>= 60 mL/min)
* 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 talazoparib administration
* All prior treatment-related toxicities must be Common Terminology Criteria for Adverse Events (CTCAE) v4.03 grade =\< 1 (except for adverse events \[AEs\] not considered to be dose-limiting toxicities \[DLTs\] in this trial such as alopecia and lymphopenia) at the time of enrollment; if there are any questions, please contact the study's principal investigator
* Females of childbearing potential must have a negative serum pregnancy test at screening
* Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

* Prior treatment with talazoparib or a poly(adenosine diphosphate \[ADP\]-ribosyl)ation (PARP)1/2 inhibitor; prior treatment with other agents that inhibit deoxyribonucleic acid (DNA) repair (i.e. WEE1 homolog \[S. pombe\] \[WEE1\] inhibitors, ataxia telangiectasia mutated \[ATM\] inhibitors), is allowed; if there are any questions, please contact the study's principal investigator
* Any major surgery, extensive radiotherapy, chemotherapy with delayed toxicity, biologic therapy, or immunotherapy must not be given within 28 days prior to study enrollment; for daily or weekly chemotherapy without the potential for delayed toxicity, a washout period of 14 days prior to enrollment may be acceptable, and questions related to this can be discussed with study principal investigator

* Symptomatic or untreated leptomeningeal or brain metastases or spinal cord compression; patients with treated central nervous system (CNS) metastasis, no longer requiring steroid therapy are potentially eligible; patients with primary glioblastoma multiforme not requiring steroid therapy will be eligible
* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmias, or psychiatric illness/social situations that would limit compliance with study requirements
