Testing Olaparib in Patients With Advanced or Metastatic (Cancer That Has Spread) Bladder Cancer and Other Genitourinary Tumors With DNA-Repair Genetic Changes

May 12, 2026 updated by: National Cancer Institute (NCI)

A Phase II Study of Olaparib (AZD2281) in Patients With Metastatic/Advanced Urothelial Carcinoma and Other Genitourinary Tumors With DNA-Repair Defects

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.

Study Overview

Detailed 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.

  • 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.

    • Note: Olaparib is a PARP inhibitor with the potential for teratogenic or abortifacient effects. Because there is a potential risk for adverse events in nursing infants secondary to treatment of the mother with olaparib, breastfeeding should be discontinued if the mother is treated with 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

  • Persistent toxicities (>= Common Terminology Criteria for Adverse Events [CTCAE] grade 2) with the exception of alopecia or peripheral neuropathy, caused by previous cancer therapy
  • Patients who are receiving any other investigational agents. Patients may be on other clinical trials or treatment during screening to determine eligibility
  • Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. A scan to confirm the absence of brain metastases is not required. Patients with spinal cord compression unless considered to have received definitive treatment for this and evidence of clinically stable disease for 28 days
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition of olaparib
  • 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.

    • 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

    • Unstable or untreated cardiac conditions or ejection fraction of < 50% as determined by echocardiogram (ECHO) or multiple gated acquisition scan (MUGA)
    • Uncontrolled diabetes mellitus
    • Psychiatric illness/social situations that would limit compliance with study requirements
  • Other severe, acute, or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration or that may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for the study
  • Immunocompromised patients, e.g., those with known HIV not on highly active antiretroviral therapy (HAART) with detectable levels of virus
  • Patients with known active hepatitis (i.e., hepatitis B or C)
  • Other malignancy within the last two (2) years except: adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS), stage 1, grade 1 endometrial carcinoma, or other solid tumors including lymphomas (without bone marrow involvement) curatively treated with no evidence of disease for >= 5 years. Patients with a history of localized triple negative breast cancer or localized resected prostate cancer may be eligible, provided they completed their adjuvant chemotherapy more than two (2) years prior to registration, and that the patient remains free of recurrent or metastatic disease
