Description

Summary

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 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.

Official Title

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

Details

PRIMARY OBJECTIVES:

  1. To evaluate the efficacy of olaparib in two cohorts of patients with metastatic/advanced urothelial carcinoma (UC) pre-selected by deoxyribonucleic acid (DNA)-repair defects as measured by overall response rate (ORR).

SECONDARY OBJECTIVES:

  1. 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.

TERTIARY OBJECTIVES:

  1. To determine the proportion of patients with DNA-repair pathway-mutated genes in metastatic UC (patient cohort referred for screening).

II. 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.

III. To explore changes in plasma cytokines and correlate with clinical response.

IV. To correlate levels of circulating endothelial cells with clinical outcome. V. To correlate levels of circulating tumor cells (CTCs) with clinical outcome. VI. To correlate peripheral immune and DNA damage response transcriptional signatures with clinical outcomes.

VII. 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.

OUTLINE:

Patients receive olaparib orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 4 weeks, every 3 months for 1 year, and annually thereafter.

Open to people ages 18 years and up

  • Patients must have a histologically confirmed diagnosis of urothelial carcinoma of the urothelial tract/bladder cancer
  • Patients must have Clinical Laboratory Improvement Act (CLIA) confirmed presence of a somatic or germline alteration considered pathogenic/likely pathogenic by FM and/or the Genetics Review Panel in one or more of the following genes: BRCA1, BRCA2, ATM, BAP1, FANCF, PALB2, and BRIP1 or in one or more of the DNA-repair genes tested in the

FoundationOne panel including the following genes: ABL1, ATR, ATRX, BARD1, BLM, BRD4, CCND1, CHEK1, CHEK2, DOT1L, FANCC, FANCD2, FANCE, FANCG, FANCL, IKBKE, MEN1, MLH1, MSH2, MSH6, MUTYH, NPM1, PMS2, POLD1, POLE, PRKDC, RAD50, RAD51, SMARCB1, STK11

  • Note: FoundationOne is a comprehensive and fully informative genomic profile that can reveal both somatic and germinal gene alterations in the tumor tissue sample; if the patient has prior evidence of a somatic or germline alterations that are considered actionable (pathogenic/likely pathogenic) by FoundationOne panel and the Genetics Review Panel in one of the genes listed in cohort 1 and 2 using FoundationOne panel prior to enrollment in this protocol, confirmation of this alteration won't be required
  • 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 =< 2 (or Karnofsky >= 60%)

  • Absolute neutrophil count >= 1,500/mcL
  • Platelets >= 100,000/mcL
