Gastrointestinal Cancer
Conditions
Brief summary
Researchers are looking for new ways to treat certain types of advanced gastrointestinal (GI) cancers. The study medicine raludotatug deruxtecan (also called MK-5909, R-DXd, or DS-6000a) is a type of medicine called an antibody-drug conjugate (ADC). An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells. The main goal of this study is to learn if the cancer responds to treatment (gets smaller or goes away).
Interventions
Administered via intravenous (IV) infusion.

Inclusion criteria
The main inclusion criteria include but are not limited to the following: * Has one of the following cancers: * Unresectable or metastatic pancreatic ductal adenocarcinoma (PDAC) * Unresectable or metastatic adenocarcinoma of the biliary tract \[intra- or extrahepatic holangiocarcinoma (CCA) or gallbladder cancer (GBC)\] * Unresectable or metastatic colorectal adenocarcinoma * Unresectable or metastatic gastric adenocarcinoma * Gastroesophageal junction adenocarcinoma (GEJAC) * Esophageal adenocarcinoma (EAC) * Has received prior therapy for the cancer * Has a life expectancy of at least 3 months * If human immunodeficiency virus (HIV) infected, must have well controlled HIV on antiretroviral therapy (ART)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Objective Response Rate (ORR) | Approximately 15 months | ORR is defined as the percentage of participants with Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1. The percentage of participants who experience CR or PR as assessed by BICR will be presented. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants who Experience One or More Adverse Events (AEs) | Up to approximately 14 months | An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants who experience an AE will be reported. |
| Number of Participants who Discontinue Study Treatment due to an AE | Up to approximately 12 months | An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants who discontinue study treatment due to an AE will be reported. |
| Duration of Response (DOR) | Up to approximately 49 months | For participants who demonstrate a confirmed Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until progressive disease (PD) or death. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. DOR as assessed by BICR will be presented. |
| Progression Free Survival (PFS) | Up to approximately 49 months | PFS is defined as the time from first day of study intervention to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as assessed by BICR. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. The appearance of one or more new lesions is also considered PD. PFS as assessed by BICR will be presented. |
| Overall Survival (OS) | Up to approximately 49 months | OS is defined as the time from the first dose to death due to any cause. |
