Pancreatic ductal adenocarcinoma (PDAC) remains a dreadful disease due to its often advanced stage at diagnosis and poor sensitivity to chemotherapy. A locally unresectable tumor (locally advanced pancreatic cancer (LAPC)) is present in 30% of the cases and is defined as a surgically unresectable tumor encasing the adjacent arteries [celiac axis, superior mesenteric artery (SMA)]. In these patients, chemotherapy has been the standard treatment for decades, optionally combined with radiotherapy. The results of small randomized trials comparing chemoradiotherapy with chemotherapy of patients with LAPC are divergent. Considering the emerging role of the tumor microenvironment (TME), the combination of checkpoint blocking antibodies with agents that target the inhibitory effects of the TME could lead to better responses in tumor historically resistant to checkpoint blocking antibody approaches. Furthermore, the addition of standard-of-care chemotherapy could further potentiate the anti-tumor effects of immunotherapy approaches by reducing the tumor burden, exposing antigens, and directly affecting the immunosuppressive TME compartment.
To explore the safety and synergy of the proposed combinatorial approach, participants with locally advanced PC will receive nivolumab and ipilimumab administered in combination with gemcitabine and nab-paclitaxel followed by immune-chemoradiation.

Experimental: Experimental
Nivolumab 3 mg/kg will be given on day 1 (± 2 days) of each 28-day treatment cycle until the progression of disease, discontinuation due to toxicity, withdrawal of consent. Ipilimumab 1 mg/kg will be given once only on day 1 cycle 1. Nivolumab will be administered as an IV infusion over 30 (± 5) minutes and then, after a 30 minutes rest period, ipilimumab will be administered as an IV infusion over 30 (± 5) minutes. Pre-medication for chemotherapy (based on standard-of-care and local institutional standards) and chemotherapy will then be administered after a further 30 minutes rest period. The recommended dose of nab-paclitaxel is 100 mg/m2 administered as an IV infusion over 30 to 40 minutes on Days 1, 8, and 15 of each 28-day cycle. Gemcitabine 800 mg/m2 will be administered over 30 to 40 minutes immediately after nab-paclitaxel on Days 1, 8, and 15 of each 28-day cycle. |

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Gender Based Eligibility: | Yes |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
-
Signed informed consent
- Subjects must have signed and dated an IRB/IEC approved written informed consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol related procedures that are not part of normal subject care
- Subjects must be willing and able to comply with scheduled visits, treatment schedule, laboratory testing, and other requirements of the study
- Histological or cytological confirmation of locally advanced pancreatic carcinoma prior to entering this study
- No prior chemotherapy regimens received for PC
- Age 18 years or older
- Life expectancy greater than 6 months
- ECOG/WHO Performance Status (PS) 0-1
- All participants will be required to undergo mandatory pre- and on-treatment biopsies at acceptable clinical risk as judged by the investigator. An archival pre-treatment sample is acceptable
-
Patients must have normal organ and marrow function as defined below:
- Absolute neutrophil count (ANC) ≥ 1.5 x 10⁹/L
- Platelet count ≥ 100 x 10⁹/L
- Serum bilirubin ≤ 1.5 x upper limit of normal (ULN) (patients with Gilbert's Syndrome must have a total bilirubin ≤ 50 mmol/L)
- AST/ALT ≤ 5 x ULN
- Serum creatinine ≤ 1.5 x ULN or CrCl ≥ 40 mL/min (using the Cockcroft-Gault formula)
- Women of child bearing potential (WOCBP) must use method(s) of contraception as indicated in Appendix 3. For a teratogenic study drug and/or when there is insufficient information to assess teratogenicity (preclinical studies have not been done), a highly effective method(s) of contraception (failure rate of less than 1% per year) is required. The individual methods of contraception and duration should be determined in consultation with the investigator. WOCBP must follow instructions for birth control when the half-life of the investigational drug is greater than 24 hours, contraception should be continued for a period of 30 days plus the time required for the investigational drug to undergo five half-lives. The half-life of nivolumab and ipilimumab is up to 25 days and 18 days, respectively. WOCBP should therefore use an adequate method to avoid pregnancy for 23 weeks (30 days plus the time required for nivolumab to undergo five half-lives) after the last dose of investigational drug
- Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year (Appendix 3). The investigator shall review contraception methods and the time period that contraception must be followed. Men that are sexually active with WOCBP must follow instructions for birth control when the half-life of the investigational drug is greater than 24 hours, contraception should be continued for a period of 90 days plus the time required for the investigational drug to undergo five half-lives. The half-life of nivolumab is up to 25 days. Men who are sexually active with WOCBP must continue contraception for 31 weeks (90 days plus the time required for nivolumab to undergo five half-lives) after the last dose of investigational drug. Women who are not of childbearing potential (ie, who are postmenopausal or surgically sterile as well as azoospermic men do not require contraception
- Subjects must have signed and dated a BIOPAC approved written informed consent form in accordance with regulatory and institutional guidelines
Exclusion Criteria:
