Study Overview
Brief Summary
The outcome of pancreatic cancer is extremely poor. NCCN guidelines recommend FOLFIRINOX or modified-FOLFIRINOX as the first-line chemotherapeutic regimen, but the response rate is unacceptably low. PD-1 blockade has been developed to a new class of cancer immunotherapy that could restore an adequate immunosurveillance against the neoplasm and enhance T-cell-mediated anticancer immune responses. Manganese has been confirmed to activate antigen-presenting cells and function as mucosal immunoadjuvants in pre-clinical studies. This one-arm, phase I/II study is designed to assess the safety and efficacy of Manganese primed combined therapy of anti-PD-1 antibody and chemotherapy.

Arms & Interventions
Manganese primed anti-PD-1 antibody plus nPG chemotherapy
Subject received Manganese primed anti-PD-1 antibody, nab-paclitaxel and gemcitabine every 3 weeks until achieving a second assessable stable disease or up to a maximum of 12 cycles. Treatment continued until progressive disease, development of unacceptable toxicity, or withdrawal of consent.
Intervention: anti-PD-1 antibody (Drug)
Manganese primed anti-PD-1 antibody plus nPG chemotherapy

Intervention: Manganese Chloride (Drug)

Outcomes
Primary Outcomes
Disease control rate (DCR)
Time Frame: 12 months
DCR is defined as the proportion of subjects who achieved a stable disease (SD), partial response (PR) or complete response (CR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
Number of Subjects with treatment-related adverse events (AEs)
Time Frame: 12 months
Incidence, nature, and severity of adverse events graded according to the NCI CTCAE v5.0. AEs were considered to be treatment-related if they had started or worsened within the interval from first study drug administration until the follow-up visit.
Secondary Outcomes
- Object response rate (ORR)(12 months)
- Progression-free survival (PFS)(12 months)
- Overall survival (OS)(24 months)
- Number of participants with laboratory test abnormalities(12 months)
