About

This study is a single-arm, multi-center, multi-cohort, prospective clinical study initiated by the investigator.

The indication of this study is: patients with advanced metastatic pancreatic cancer who have progressed after first-line chemotherapy. Eligible patients will be assigned to liposomal irinotecan (nal-IRI) plus 5-fluorouracil (5-FU)/leucovorin (LV) (nal-IRI/5-FU/LV) combined with benmelstobart and anlotinib ± SBRT.

The total sample size for this study is expected to be 56 subjects.

Full description

For patients with advanced metastatic pancreatic cancer who failed first-line treatment, the screening and enrollment will be completed according to the enrollment and exclusion criteria described in the study protocol, and the informed consent form will be signed after full communication. After enrollment, patients will be treated with cohort A) or cohort B), and followed up regularly.

Cohort A: nal-IRI/5-FU/LV + PD-L1 inhibitor + multi-target anti-angiogenic small molecule:

Irinotecan liposome: 50mg/m2 IV D1, D15 LV: 400mg/m2 IV D1, D15 5-FU ：2.4g/m2 CIV 46h D1, D15 bemosubaemab: 1200mg IV Q3W Anlotinib: 12mg po D1-D14 Q3W

Cohort B: nal-IRI/5-FU/LV + PD-L1 inhibitor+ multi-target anti-angiogenic small molecule+SBRT Group:

Irinotecan liposomes: 50mg/m2 IV D1, D15 LV: 400mg/m2 IV D1, D15 5-FU ：2.4g/m2 CIV 46h D1, D15 bemosubaemab: 1200mg IV Q3W Anlotinib: 12mg po D1-D14 Q3W SBRT
