A Pilot Study of a GVAX Pancreas Vaccine (With Cyclophosphamide) in Combination With a PD-1 Blockade Antibody (Pembrolizumab) and a Macrophage Targeting Agent (CSF1R Inhibitor) for the Treatment of Patients With Borderline Resectable Adenocarcinoma of the Pancreas
In Brief
A Early Phase 1 clinical trial evaluating Cyclophosphamide, GVAX Pancreas Vaccine (GVAX), and 2 other interventions for Pancreatic Cancer. Completed, enrolled 11 participants across 1 site.
Detailed Summary
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.

Interventions
200 mg/m\^2, intravenous (IV) infusion 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.
5x10\^8 cells, six intradermal (ID) injections 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.

75 mg (dose level 1) or 100 mg (dose level 2), intravenous (IV) infusion 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).
