Summary

Pancreatic cancer is a kind of digestive system tumor with extremely high malignancy and poor prognosis. Although the trend of benefit from immunotherapy in combination with chemotherapy is currently reflected in several exploratory studies, the overall efficacy is still relatively limited.

Dysregulation of epigenetic mechanisms, which is common in cancer, leads to down-regulation of genes involved in tumor antigen processing or presentation, resulting in immune evasion and thus affecting the efficacy of immunotherapy. Epigenetic inhibitors may enhance the efficacy of immunotherapy by enhancing antigenicity and presentation of tumor-associated antigens, reprogramming the tumor microenvironment to counteract immunosuppression, and reversing cytotoxic T-cell depletion. Thus, decitabine-promoted immunotherapeutic sensitization is a potential therapeutic avenue for mPDAC patients that warrants further exploration in clinical trials. Taking into account the characteristics of pancreatic cancer immunophenotype, exploring combination therapy regimens that enhance anti-tumor immune response and improve the efficacy of immunotherapy has become an urgent clinical problem.

This study is a prospective, single-arm, single-center, phase IB/II clinical study exploring the efficacy and safety of adebrelimab in combination with decitabine, albumin-bound paclitaxel, and gemcitabine in the first-line treatment of metastatic pancreatic cancer. The primary study endpoints are DLT, RP2D and ORR. Secondary study endpoints are OS, PFS, DCR, DoR and safety.
