This study investigates advanced gastrointestinal cancers. The purpose of this study is to determine the safety and effectiveness of an investigational medication for individuals with these conditions.
This study evaluates how the investigational medication is processed by the body and its overall safety and effectiveness. Participants will be monitored to see how well the treatment works.
- Who can participate: Adults aged 18 years and older with advanced gastrointestinal cancers that cannot be surgically removed may be eligible. Key factors include having previously received treatment and providing tumor tissue samples.
- Study details: Participants will receive either the investigational medication alone or in combination with other treatments. Some participants may receive a placebo, which is an inactive substance that looks like the investigational medicine but does not contain any medicine.
