I. To evaluate the efficacy of olaparib in two cohorts of patients with metastatic/advanced urothelial carcinoma (UC) pre-selected by DNA-repair defects as measured by overall response rate (ORR).
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.
I. To determine the proportion of patients with DNA-repair pathway-mutated genes in metastatic UC (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 UC 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.
OUTLINE: Patients are assigned to 1 of 2 cohorts.
COHORT I: Patients that have cancer-associated DNA-repair gene mutations receive olaparib orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
COHORT II: Patients that do not have cancer-associated DNA-repair gene mutations undergo blood sample collection at baseline.
After completion of study treatment, patients are followed up at 4 weeks, every 2 months for 1 year, then every 3 months thereafter.

|Official Title:||A Phase II Study of Olaparib (AZD2281) in Patients With Metastatic/Advanced Urothelial Carcinoma With DNA-Repair Defects|
|Actual Study Start Date :||August 3, 2018|
|Estimated Primary Completion Date :||August 21, 2023|
|Estimated Study Completion Date :||August 21, 2023|
Experimental: Cohort I (olaparib)
Patients that have cancer-associated DNA-repair gene mutations receive olaparib PO BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Experimental: Cohort II (biospecimen collection)
Patients that do not have cancer-associated DNA-repair gene mutations undergo blood sample collection at baseline.
Procedure: Biospecimen Collection
Undergo blood collection
- Overall response rate (ORR) [ Time Frame: Up to 5 years ]Will be evaluated by Response Evaluation Criteria in Solid Tumors (RECIST). ORR will be reported along with 95% exact confidence intervals.
- Progression free survival (PFS) [ Time Frame: From the date of olaparib initiation to investigator-assessed clinical progression or radiographic progression (by RECIST), or death from any cause, whichever occurs first, assessed up to 5 years ]PFS will be determined using a Kaplan-Meier curve, with probabilities at various time points indicated along with appropriate confidence intervals.
- Incidence of adverse events [ Time Frame: Up to 5 years ]Will be assessed according to the Common Terminology Criteria for Adverse Events version 5.0.
- Individual deoxyribonucleic acid (DNA)-repair defects [ Time Frame: Up to 5 years ]The association between individual DNA-repair defects and ORR will be determined using Fisher's exact test.
