Testing onvansertib plus chemo for first-line advanced pancreatic cancer
This trial tests a new drug called onvansertib combined with standard chemotherapy (NALIRIFOX) as the first treatment for advanced pancreatic cancer that cannot be removed by surgery or has spread. The goal is to see if adding onvansertib helps shrink tumors or slow the cancer better than chemo alone.
