Cadonilimab with S-1 or Capecitabine for advanced pancreatic cancer

A Single-arm Phase II Clinical Study of Cadonilimab Combined With S-1 or Capecitabine as Second-line Treatment for Patients With Advanced Pancreatic Cancer

Phase 2 Interventional Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine · NCT06532617

This study is testing if a new combination of Cadonilimab with either S-1 or capecitabine can help people with advanced pancreatic cancer who have already tried other treatments.

What this trial studies

This clinical trial evaluates the effectiveness and safety of Cadonilimab, a PD-1/CTLA-4 bispecific antibody, when combined with either S-1 or capecitabine as a second-line treatment for patients with advanced pancreatic cancer. It is a single-arm, single-center phase II trial, focusing on patients who have previously undergone standard first-line treatments. The study aims to determine how well this combination therapy works in managing locally advanced pancreatic ductal adenocarcinoma.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-80 with histopathologically confirmed locally advanced pancreatic ductal adenocarcinoma who have received prior standard treatment.

Not a fit: Patients with distant metastasis or those who have not received any prior anti-tumor treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with advanced pancreatic cancer who have limited treatment choices.

How similar studies have performed: While this approach is novel in the context of pancreatic cancer, similar immunotherapy strategies have shown promise in other malignancies.

Main Inclusion Criteria:

* Signed written informed consent
* Age 18-80, female or male
* Histopathologically confirmed pancreatic ductal adenocarcinoma
* Patients with locally advanced pancreatic cancer who have previously received standard first-line anti-tumor treatment (radiotherapy, chemotherapy, targeted or immunotherapy, etc.)
* Locally advanced pancreatic cancer is defined as follows: a. The tumor has no distant metastasis; b. Pancreatic head/uncinate process: The tumor contacts the superior mesenteric artery \>180˚; c. Pancreatic body and tail: The tumor contacts the superior mesenteric artery or celiac artery \>180˚; The tumor contacts the celiac artery and infiltrates the abdominal aorta; d. The tumor invades the jejunal branch of the superior mesenteric artery. Portal vein-superior mesenteric vein cannot be safely reconstructed due to tumor invasion, vein occlusion, or involvement of a large range of jejunal branches of the superior mesenteric vein.
