About
The purpose of this study is to evaluate whether combining cyclophosphamide (CY), pembrolizumab, GVAX and IMC-CS4 is effective and safe in patients with borderline resectable pancreatic cancer.
Full description
This was a single center, open label, pilot study to evaluate the safety and intratumoral immune response of neoadjuvant/adjuvant triplet immunotherapy: CY/GVAX, Pembrolizumab, and IMC-CS4 in patients with resectable or borderline resectable Pancreatic ductal adenocarcinoma.
Patients received the combination of CY/GVAX with pembrolizumab and IMC-CS4 following completion of standard neoadjuvant chemotherapy (with or without radiation). Immunotherapy agents were given prior to and after surgical resection.
Patients receive neoadjuvant immunotherapy consisting of cyclophosphamide and pembrolizumab on day 1, IMC-CS4 on days 1, 8, and 15, and GVAX on day 2 of Cycles 1 and 2 (3 weeks/cycle). Patients will then undergo pancreaticoduodenectomy 2-3 weeks later, followed by standard of care adjuvant chemotherapy at the discretion of the primary oncologist. Patients may then receive 4 cycles (3 weeks/cycle) of adjuvant immunotherapy (same regimen as Cycles 1 and 2). Disease free patients may receive an additional 12 booster cycles (3 weeks/cycle) of immunotherapy consisting of pembrolizumab on day 1 of all 12 booster cycles, as well as cyclophosphamide on day 1 and GVAX on day 2 of the 6th and 12th booster cycle.
