  • Drug: Olaparib

Purpose: This phase II trial studies how well olaparib works in treating patients with urothelial cancer with DNA-repair defects that has spread to other places in the body (advanced or metastatic) and usually cannot be cured or controlled with treatment. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

  • Note: FoundationOneCDx (F1CDx) is a next generation sequencing based in vitro diagnostic device for detection of substitutions, insertion and deletion alterations (indels), and copy number alterations (CNAs) in 324 genes and select gene rearrangements, as well as genomic signatures including microsatellite instability (MSI) and tumor mutational burden (TMB) using DNA isolated from formalin-fixed paraffin embedded (FFPE) tumor tissue specimens
  • 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 computed tomography (CT) scan, magnetic resonance imaging (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)
  • 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 >= 10 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
  • 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 one (1) month 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 tumor sample for mutation analysis or be willing to undergo mandatory screening biopsy
  • Patients must have a life expectancy >= 16 weeks
  • Postmenopausal or evidence of non-childbearing status for women of childbearing potential: negative urine or serum pregnancy test within 28 days of study treatment and confirmed prior to treatment on day 1
  • Postmenopausal is defined as:
  • Amenorrheic for 1 year or more following cessation of exogenous hormonal treatments
  • Luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels in the post menopausal range for women under 50
  • Radiation-induced oophorectomy with last menses > 1 year ago

  • Patients who have had prior treatment with olaparib or any other PARP inhibitor (PARPi)
  • Patients with myelodysplastic syndrome/acute myeloid leukemia; or baseline features suggestive of myelodysplastic syndrome or acute myelogenous leukemia on peripheral blood smear or bone marrow biopsy, if clinically indicated
  • Persistent toxicities (>= Common Terminology Criteria for Adverse Events [CTCAE] grade 2) with the exception of alopecia, 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 any medications or substances that are inhibitors or inducers of CYP3A are ineligible; a washout period prior to starting olaparib for patients on CYP3A inhibitors is 2 weeks; and the required washout period for CYP3A inducers is 5 weeks for enzalutamide or phenobarbital and 3 weeks for other agents
  • 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
  • Any chronic or concurrent acute liver disease
  • History of stroke, transient ischemic attack (TIA), or myocardial infarction, within 6 months prior to enrollment
  • Uncontrolled concurrent disease or illness including but not limited to:

  • 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., patients who are known to be serologically positive for human immunodeficiency virus (HIV)
  • Patients with known active hepatitis (i.e., hepatitis B or C) due to risk of transmitting the infection through blood or other body fluids
