Overview
The goal of this clinical trial is to assess the efficacy and safety of Pimicotinib (ABSK021) in combination with chemotherapy with or without Toripalimab in patients with advanced pancreatic cancer. The main questions it aims to answer are:
- Whether the Pimicotinib (ABSK021) in combination with chemotherapy with or without Toripalimab is safe in patients with advanced pancreatic cancer.
- Whether the Pimicotinib (ABSK021) in combination with chemotherapy with or without Toripalimab is effective in patients with advanced pancreatic cancer.
Participants will be asked to complete the study procedures:
- Receive the administration of Pimicotinib (ABSK021) in combination with chemotherapy with or without Toripalimab about 24 weeks in study Part A or Part B.
- Receive the administration of Pimicotinib(ABSK021) about 24 weeks in study part 2.
- Complete the study procedures specified in the protocol, which is guided by researchers.
Description
This is a phase II, open-label study to evaluate safety, tolerability, pharmacokinetics (PK), and clinical benefit of Pimicotinib (ABSK021) in combination with chemotherapy with or without Toripalimab in patients with advanced pancreatic cancer.
