The Purpose of This Study
This clinical trial is evaluating an investigational treatment combination for participants with advanced or metastatic solid tumors. Specifically, the study focuses on breast cancer or gastric cancer where the tumors have spread to other parts of the body and are harder to treat.
Focusing on HER2
Participants in this study must have tumors that express HER2. The presence of HER2 can cause cancer to grow more quickly or spread faster. Currently, there are limited treatment options for patients with advanced solid tumors expressing HER2, making this research critical.
How the Treatment Works
- Investigational DrugUses disitamab vedotin (DV), an antibody drug conjugate (ADC) designed to stick to and eliminate cancer cells.
- Combination TherapyDV is paired with tucatinib (TUKYSA®), a drug already approved to treat certain cancers in multiple countries.
- Careful EvaluationThe study team will closely monitor how safe and effective this combination is, while documenting any side effects.
