COMPASS-B-MUHC: Molecular Profiling of Advanced Biliary Tract Cancers
Study Details
Study Description
Brief Summary
Biliary tract cancer (BTC) accounts for <1% of all cancers, but remains a highly fatal malignancy. Surgical resection is the only hope for cure, but most patients present with advanced disease when curative-intent surgery is not possible. The therapeutic options for patients with advanced disease are limited, primarily to chemotherapeutic regimens, which are based on empiric evidence without the use of biomarkers. These current treatment strategies have been largely ineffective in controlling the disease, resulting in poor survival outcomes of less than 1 year. An understanding of the molecular characteristics of biliary tract cancer may enable stratification of patients into therapies that target specific molecular alterations with greater efficacies and improved clinical outcomes. This study aims to investigate the feasibility and clinical utility of prospective molecular profiling of advanced biliary tract cancer. The primary endpoint of this study is to demonstrate the feasibility of returning whole genome sequencing results within 8 weeks of tumour biopsy for second-line treatment consideration (n=30 patients). In parallel, tumour whole transcriptome sequencing will be performed to identify actionable molecular alterations (e.g., fusion transcripts). Once the primary endpoint is met, the study will be expanded. Current funding allows expansion to 40 patients in total.

Outcome Measures
Primary Outcome Measures
- Number of participants with tumour whole genome sequencing returned within 8 weeks [2 years]
We have estimated that 30 patients will be required to reach the primary end point, which will be met if we demonstrate that tumor whole genome sequencing data is available at 8 weeks from the tumour biopsy for 80% of patients.
Secondary Outcome Measures
- Disease control rate [4 years]
Number of patients that achieve stability of disease (cancer) by imaging (RECIST criteria) with first-line standard chemotherapy, consisting of gemcitabine backbone.
- Progression-free survival rate [4 years]
Progression free survival (PFS) defined as the interval between the date of registration and the earliest date of disease progression or death due to any cause of patients treated with 1st line chemotherapy.
- Overall survival rate [4 years]
Overall survival (OS) defined as the interval between the date of registration and the date of death of patients treated with 1st line chemotherapy.
- Number of patients in whom at least 1 actionable mutation is identified [4 years]
based on whole genome sequencing or RNA sequencing analyses.
- Number of patients who received a targeted therapy (after first-line treatment) [4 years]
based on the identification of an actionable mutation by whole genome sequencing or RNA sequencing.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Patients must have a histological or radiological diagnosis of inoperable or metastatic BTC.

Patients who are currently on anti-cancer treatment.
-
Patients with known brain metastases.
-
Uncontrolled concurrent illness that would limit compliance with study requirements.
-
Any other condition that would contraindicate the patient's participation due to safety concerns or compliance with clinical study procedures.
