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

• Status: Recruiting
• Trial end date: 2023-08-21
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies how well olaparib works in treating patients with urothelial cancer 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.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Olaparib; Poly(ADP-ribose) Polymerase Inhibitors

• 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 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 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

• 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

• Chemotherapy-induced menopause with > 1 year interval since last menses

• Surgical sterilization (bilateral oophorectomy or hysterectomy)

• Patients is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations

Exclusion Criteria:

• 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

• 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
