About
This phase II trial studies how well olaparib works in treating patients with bladder cancer and other genitourinary tumors with deoxyribonucleic acid (DNA)-repair defects that has spread to other places in the body (advanced or metastatic) and usually cannot be cured or controlled with treatment. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing.
Full description
PRIMARY OBJECTIVE:
I. To evaluate the efficacy of olaparib in two cohorts of patients with metastatic/advanced non prostate genitourinary (GU) cancer pre-selected by DNA-repair defects as measured by overall response rate (ORR).
SECONDARY OBJECTIVES:
I. To describe the effect of therapy on progression free survival (PFS). II. To describe the effect of therapy on overall survival (OS). III. To describe the safety/tolerability and drug-related toxicities of olaparib.
IV. To follow patients without the pre-selected DNA-repair defects for survival. (Cohort 3 only)
CORRELATIVE OBJECTIVES:
I. To determine the proportion of patients with DNA-repair pathway-mutated genes in metastatic non-prostate GU cancer (patient cohort referred for screening).
II. To correlate levels of baseline circulating tumor cells (CTCs) with survival in untreated patients.
III. To explore tumor-mutational profiles in metastatic tumor biopsies, saliva "normal" DNA, changes in tumor or peripheral immune characteristics, or tumor associated somatic mutation load in blood DNA in response to treatment.
IV. To explore changes in plasma cytokines and correlate with clinical response.
V. To correlate levels of circulating endothelial cells with clinical outcome. VI. To correlate levels of circulating tumor cells (CTCs) with clinical outcome.
VII. To correlate peripheral immune and DNA damage response transcriptional signatures with clinical outcomes.
VIII. To determine the effectiveness of using next-generation sequencing (NGS) to identify DNA-repair pathway gene defects in tumor samples and circulating DNA and identify patients with non-prostate GU cancer suitable for PARP inhibition.
IX. To determine the expression of Schlafen 11 (SLFN11) in tumor versus (vs.) stroma cells, and the potential tumor heterogeneity based on SLFN11 expression.
X. To determine if the levels of hyaluron (HA) detected in circulating plasma correlates with outcomes in patients treated with olaparib.
XI. To determine if the levels of HGF and MET detected in circulating plasma correlates with outcomes in patients with olaparib.
OUTLINE: Patients are assigned to 1 of 3 cohorts.
COHORT I and II: Patients that have cancer-associated DNA-repair gene mutations receive olaparib orally (PO) twice daily (BID) on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo blood sample collection, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET)/CT, or bone scan and optional tumor biopsy and bone marrow biopsy on study.
COHORT III: Patients that do not have cancer-associated DNA-repair gene mutations undergo blood sample collection at baseline. Additionally, patients undergo CT, MRI, PET/CT, or bone scan and optional tumor biopsy and bone marrow biopsy on study.
After completion of study treatment, patients are followed up at 4 weeks, every 2 months for 1 year, then every 3 months thereafter.

Inclusion criteria
Patients must have a histologically confirmed diagnosis non-prostate GU cancer
Patients with the presence of cancer-associated genetic mutations in one or more pathogenic or likely pathogenic gene alterations tested in the FoundationOne FoundationOne®CDx (F1CDx) panel will be enrolled in cohorts 1 or 2 as follows:
Patients with benign or variants of unknown significance as determined by FoundationOne FoundationOne®CDx (F1CDx) panel and Genetics Review Panel review will be enrolled in Cohort 3 to be followed for survival
Foundation One mutation analysis results performed prior to enrollment on this study may be accepted for eligibility review and in the event that a patient cannot undergo a biopsy and tumor is not available, Foundation Medicine liquid biopsy may be performed
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 CT scan, MRI, or calipers by clinical exam
Evidence of disease progression as defined by Response Evaluation Criteria in Solid Tumors (RECIST) (version 1.1) during treatment or after the most recent dose of therapy with at least one platinum-based regimen of chemotherapy and/or an immune-checkpoint inhibitor (atezolizumab, pembrolizumab, nivolumab, avelumab or durvalumab) (2-week washout from chemotherapy and 4-weeks washout from monoclonal antibodies is required)
Age >= 18 years. Because no dosing or adverse event data are currently available on the use of olaparib in patients < 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials
Eastern Cooperative Oncology Group (ECOG) performance status =< 1 (or Karnofsky >= 70%)
Leukocytes >= 3,000/mcL
Absolute neutrophil count >= 1,500/mcL
Platelets >= 100,000/mcL
Total bilirubin =< 1.5 x upper limit of normal (ULN) (for subjects with documented Gilbert's disease total bilirubin =< 3.0 mg/dL)
Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal (for subjects with liver metastasis AST/ALT =< 5 x ULN)
Creatinine clearance >= 50 mL/min/1.73 m^2
Hemoglobin >= 9 g/dL; transfusions are allowed
Prothrombin time (PT)/international normalized ratio (INR) and activated partial thromboplastin time (aPTT) within 1.25 x ULN institutional limits, except where a lupus anti-coagulant has been confirmed or the patient is on direct oral anticoagulant (DOA)
Patients must be able to tolerate oral medications and not have gastrointestinal illnesses that would preclude absorption of olaparib
Pre-clinical data indicate that olaparib adversely affects embryofetal survival and development. Therefore, women of child-bearing potential and their partners should agree to use two (2) highly effective forms of contraception throughout study participation and for at least six (6) months after the last dose of olaparib. Male study participants should avoid fathering a child or donating sperm during the study and for three (3) months after the last dose of olaparib.
Ability to understand and the willingness to sign a written informed consent document or patients with impaired decision making capacity (IDMC) if they are represented by a legally authorized representative (LAR)
Patients must provide archival tumor sample for mutation analysis or be willing to undergo mandatory screening biopsy. In the event that the patient cannot undergo biopsy and tumor is not available, Foundation Medicine liquid biopsy will be performed

Patients receiving strong or moderate CYP3A inhibitors or inducers are ineligible. A washout period prior to the first dose of olaparib for patients on CYP3A inhibitors/inducers is 5 half-lives or 3 weeks , whichever is shorter. Medications with limited systemic absorption (e.g., ophthalmic, otic) do not require a washout and are permitted.
Pregnant women are excluded from this study because olaparib is a PARP inhibitor agent with the potential for teratogenic or abortifacient effects
