About

This study is an Ib/II phase clinical trial evaluating the safety and efficacy of IBI363 combined with chemotherapy as a second-line treatment for unresectable locally advanced or metastatic pancreatic cancer.

Approximately 39-48 patients with unresectable locally advanced or metastatic pancreatic cancer, who have progressed on or are intolerant to first-line chemotherapy (albumin-bound paclitaxel + gemcitabine, AG regimen), will be enrolled. Treatment involves IBI363 combined with chemotherapy and continues until disease progression, death, intolerable toxicity, withdrawal of informed consent, initiation of new antitumor therapy, or other protocol-specified reasons for discontinuation.
