A Phase 1b/2 Open-Label Study of Disitamab Vedotin in Combination With Other Anticancer Therapies in Solid Tumors
Seagen, a wholly owned subsidiary of Pfizer
Summary
This clinical trial is studying solid tumor cancers. A solid tumor is one that starts in part of your body like your lungs or liver instead of your blood. Once they've grown bigger in one spot or spread to other parts of the body, they're harder to treat. This is called advanced or metastatic cancer. Participants in this study must have breast cancer or gastric cancer. Participants must have tumors that have HER2 on them. This allows the cancer to grow more quickly or spread faster. There are few treatment options for patients with advanced or metastatic solid tumors that express HER2. This clinical trial uses an experimental drug called disitamab vedotin (DV). Disitamab vedotin is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial uses a drug called tucatinib, which has been approved to treat cancer in the United States and some other countries. This drug is sold under the brand name TUKYSA®. This study will test how safe and how well DV with tucatinib works for participants with solid tumors. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.
Description
This clinical trial is to evaluate disitamab vedotin in combination with tucatinib in subjects with LA/metastatic breast cancer or gastric cancer/GEJC that express HER2. The study has a dose escalation phase evaluating disitamab vedotin plus tucatinib followed by a dose optimization phase. The 2 dose levels identified in the dose escalation phase will be assessed in the optimization phase for both safety and efficacy in HER2-expressing LA/mBC and LA/mGC/GEJC. Once the safety and efficacy profile of disitamab vedotin plus tucatinib has been established and a disitamab vedotin dose with the opti…
