This study focuses on treating patients with advanced solid gastrointestinal tumors, including colorectal cancer, pancreatic cancer, gastric cancer, and cholangiocarcinoma. The research evaluates a new treatment that combines an investigational drug called BOLD-100 with a standard chemotherapy regimen known as FOLFOX. FOLFOX consists of three medications: fluorouracil, folinic acid, and oxaliplatin.
The purpose of this study is to determine the safety and effectiveness of combining BOLD-100 with FOLFOX chemotherapy in treating these types of cancers. The study is conducted in two parts. In the first part, different dose levels of BOLD-100 will be tested to find the safest and most appropriate dose. In the second part, the selected dose will be given to more patients to further study how well the treatment works.
During the study, participants will receive BOLD-100 and FOLFOX through an intravenous line (a small tube inserted into a vein). The medications will be given according to a specific schedule determined by the healthcare team. Throughout the treatment, patients will have regular check-ups to monitor their health and how well the treatment is working.
