Brief Summary
The purpose of this pilot study is to examine the safety and feasibility of histotripsy in two cohorts of 12 patients each with Biliary Track Cancer (BTC), with a plan to expand to a larger multi-center study if both safety and feasibility are demonstrated. All patients from cohort 1 will be evaluated for objective response rate (ORR), duration of response (DOR), disease control rate (DCR), progression free survival (PFS) and overall survival (OS) of histotripsy in combination with chemoimmunotherapy. Toxicity profile of histotripsy will be characterized for this cohort. For Cohort 2, in addition to the above evaluations, changes in serum bilirubin levels (total and direct) over time, time to biliary decompression or normalization of bilirubin (total and direct), and percent of patients rendered eligible for chemoimmunotherapy with GCD/P will also be assessed.

Study Arms (2)
Cohort 1: Patients eligible for chemoimmunotherapy
EXPERIMENTALEligible patients will undergo histotripsy and therapy with GCD/P (gemcitabine 1,000 mg/m2 IV and cisplatin 25 mg/m2 IV days 1 and 8 with durvalumab 1,500 mg IV or pembrolizumab 200 mg IV day 1 in 21-day cycles) until disease progression or intolerable toxicity. Patients will have the option of narrowing to maintenance durvalumab/pembrolizumab with or without gemcitabine after 4-6 months of GCD/P as per standard-of-care.
Cohort 2: Patients not eligible for chemoimmunotherapy
EXPERIMENTALEligible patients will undergo histotripsy (with or without standard of care biliary tract stenting) and then be monitored with weekly hepatic function panels and clinic visits to monitor status of biliary tract obstruction and for candidacy for chemoimmunotherapy. Patients who become eligible for chemoimmunotherapy will undergo treatment with GCD/P as per Cohort 1 until disease progression or intolerable toxicity following the same peripheral blood and imaging schedule as Cohort 1.
Interventions
1000 mg/m2 over 30 minutes on Days 1, 8, of each cycle (every 3 weeks), infused according to local labeling.
The reconstituted solution should be administered by IV infusion over a 6- to 8-hour period. Cisplatin is given on Days 1 and 8 of each cycle (every 3 weeks), infused according to local labeling
Given on day 1 of each cycle (every 3 weeks), infused according to local labeling. Administer infusion solution intravenously over 60 minutes through an intravenous line containing a sterile, low-protein binding 0.2 or 0.22 micron in-line filter.
Given on day 1 of each cycle (every 3 weeks), infused according to local labeling. Administer diluted solution intravenously over 30 minutes through an intravenous line containing a sterile, non-pyrogenic, low-protein binding 0.2 micron to 5 micron in-line or add-on filter.
Histotripsy is a non-invasive medical technique that uses focused ultrasound waves to mechanically break down and destroy targeted tissues through a process called cavitation.
