Filter by:This study is a non-randomized, open-label, multi-cohort, multi-site, pilot feasibility therapeutic trial. The study will enroll 20 patients across 4 cohorts (CRC, gastric, PDAC, and HCC/intra-hepatic-/extra-hepatic-, gall bladder adenocarcinomas) diagnosed with histologically confirmed GI cancers. These patients will have already completed all Standard of Care (SOC) treatments (including neoadjuvant, surgery, local therapies, and/or adjuvant therapy as applicable), as defined by the treating primary physician or research team, with curative intent but have a positive SignateraTM tumor-informed ctDNA test and NED radiographically by standard imaging within 28 days prior to enrollment and within 1 year of completing all curative-intent therapy. All patients will be treated with intravenous (IV) atezolizumab 1200 mg IV and bevacizumab 15 mg/kg on Day 1 of 21-day cycles until disease recurrence, ctDNA POD, unacceptable toxicity, or subject withdrawal of consent with a maximum 12 month total duration of study therapy. Atezolizumab and bevacizumab drug will be provided.
Gallbladder adenocarcinoma is a devastating disease associated with a poor prognosis. Gallbladder and other biliary cancers will be responsible for an estimated 11,980 new cases, and 4,090 deaths in the US during 2020. The 5-year survival for all patients with gallbladder cancer is 18%, however this plummets to 2% for patients with metastatic disease. Patients with gallbladder cancer frequently develop peritoneal recurrence, particularly after intra-operative bile spillage during cholecystectomy for incidentally discovered gallbladder malignancy. Once developed, peritoneal metastases are difficult to treat and result in significant morbidity and mortality. As a result, novel approaches that target peritoneal metastases are needed for this disease. Prophylactic use of heated intraperitoneal chemotherapy (HIPEC) has been explored or is under active investigation for numerous gastrointestinal malignancies, including colon, gastric, and appendiceal cancers. HIPEC has efficacy in gallbladder cancer patients with macroscopic peritoneal disease undergoing cytoreductive surgery (CRS)/HIPEC and has been associated with a survival advantage in a multi-institutional retrospective case series. Incidentally discovered gallbladder cancer is treated with central hepatectomy and portal lymphadenectomy, therefore a prophylactic HIPEC can be easily incorporated into the second operation performed as part of the standard of care. In this early phase clinical trial, the investigators will explore the safety and feasibility of prophylactic HIPEC for gallbladder cancer in patients at high-risk of peritoneal recurrence. The primary endpoint is to assess feasibility of the prophylactic heated intraperitoneal chemotherapy (HIPEC) approach in gallbladder cancer. The primary endpoints include occurrence of intra-operative complications, technical challenges, 90-day postoperative morbidity and mortality, length of stay and readmission, which will be documented and compared with historical controls after follow-up.
