Clinical Trial Summary

This is a single arm open label multi-institutional phase II trial of olaparib monotherapy in subjects with metastatic urothelial cancer harboring somatic DNA damage response (DDR) alterations. The primary objective of the study is to estimate the objective response rate (per RECIST 1.1) to treatment with olaparib.

All subjects must have adequate archival tissue available prior to registration (i.e., at least 15 unstained slides or paraffin block). Archival tissue should represent invasive or metastatic urothelial cancer with a preference for metastatic tissue if available. Archival tissue should be identified at screening and shipped by C1D1. Subjects without adequate tissue may be considered on a case by case basis after discussion with the sponsor-investigator. Exclusion Criteria - Active infection requiring systemic therapy. - Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study). - Known additional malignancy that is active and/or progressive requiring treatment; subjects with other malignancies that have been definitively treated and who have been rendered disease free will be eligible. - Prior treatment with a PARP inhibitor, including olaparib. - Treatment with any investigational drug within 30 days prior to registration. - Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site). - Resting ECG with QTc > 470 msec on 2 or more time points within a 24 hour period or family history of long QT syndrome. - Concomitant use of known strong CYP3A inhibitors (eg. itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (eg. ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil). The required washout period prior to starting olaparib is 2 weeks. - Concomitant use of known strong (eg. phenobarbital, enzalutamide, phenytoin, rifampicin, rifabutin, rifapentine, carbamazepine, nevirapine and St John's Wort) or moderate CYP3A inducers (eg. bosentan, efavirenz, modafinil). The required washout period prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital and 3 weeks for other agents. - Subjects with myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of MDS/AML. - Major surgery within 2 weeks of starting study treatment and subjects must have recovered from any effects of any major surgery. - Subjects considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on High Resolution Computed Tomography (HRCT) scan, history of pneumonitis, or any psychiatric disorder that prohibits obtaining informed consent. - Subjects unable to swallow orally administered medication and subjects with gastrointestinal disorders likely to interfere with absorption of the study medication. - Immunocompromised subjects, e.g., subjects who are known to be serologically positive for human immunodeficiency virus (HIV). - Subjects with a known hypersensitivity to olaparib or any of the excipients of the product. - Subjects with known active hepatitis (i.e. Hepatitis B or C) due to risk of transmitting the infection through blood or other body fluids - Previous allogeneic bone marrow transplant or double umbilical cord blood transplantation (dUCBT)

Outcome

Type Measure Description Time frame Safety issue
Other Overall Survival (OS) Overall survival is defined as the time from treatment start until death or date of last contact. Time of treatment start until death or date of last contact, up to a maximum of 23 months.
Other Adverse Events Number of participants with treatment related adverse events are reported by CTCAEv4 term and grade. AE had been recorded from time of signed informed consent until 30 days after discontinuation of study drug(s) or until a new anti-cancer treatment starts, whichever occurs first, up to a maximum of 18 months.
Primary Objective Response Rate (ORR) Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST): Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD) >= 20% increase in tumor burden relative to nadir or the appearance of one or more new lesions; Stable Disease (SD), not meet criteria for CR/PR/PD.
ORR is defined as the proportion of all subjects with confirmed PR or CR according to RECIST 1.1.
Up to a maximum of 17 months
Secondary Progression-Free Survival (PFS) Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST): Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD) >= 20% increase in tumor burden relative to nadir or the appearance of one or more new lesions; Stable Disease (SD), not meet criteria for CR/PR/PD. PFS is defined as time from registration until disease progression met by RECIST 1.1 or death from any cause. Time of treatment start until the criteria for disease progression or death. Up to a maximum of 17 months.
