| NCT03153410 | Pilot Study With CY, Pembrolizumab, GVAX, and IMC-CS4 (LY3022855) in Patients With Borderline Resectable Adenocarcinoma of the Pancreas | EARLY_PHASE1 | COMPLETED | 11 | — | — | Sep 27, 2018 | Aug 29, 2023 | Jan 9, 2025 | 1 | United States |
Treatment-related immunologic effect is defined as an 80% or greater increase in the number of CD8+ T cells (and at least 1.8 times the baseline median absolute deviation) in surgically resected tumor tissue in comparison to the baseline biopsy in subjects that received at least 1 dose of neoadjuvant combination immunotherapy and underwent a R0, R1, or R2 surgical resection.

| Name | Type | Description |
|---|---|---|
| Cyclophosphamide | DRUG | 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. |
| GVAX Pancreas Vaccine (GVAX) | DRUG | 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. |
| Pembrolizumab | DRUG | 200 mg, 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).

| IMC-CS4 | DRUG | 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). Patients will then undergo pancreaticoduodenectomy 2-3 weeks later, followed by standard of care adjuvant chemotherapy at the discretion of the primary oncologist.
