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.

Medications with limited systemic absorption (e.g., ophthalmic, otic) do not require a washout and are permitted.
- Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference texts such as the Physicians' Desk Reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
-
Pregnant women are excluded from this study because olaparib is a PARP inhibitor agent with the potential for teratogenic or abortifacient effects
