"We look forward to the presentation featuring antibody-drug conjugate enfortumab vedotin in combination with the immune therapy pembrolizumab in patients with previously untreated advanced urothelial cancer," said Roger Dansey, M.D., Chief Medical Officer at Seattle Genetics. "We are also pleased to see initial results from an investigator-sponsored study called MOUNTAINEER examining the combination of our novel tyrosine kinase inhibitor tucatinib with trastuzumab for the treatment of HER2-amplified metastatic colorectal cancer. The development of these and other targeted medicines support our efforts toward becoming a multi-product oncology company."

About Enfortumab Vedotin
Enfortumab vedotin is an investigational antibody-drug conjugate (ADC) composed of an anti-Nectin-4 monoclonal antibody attached to a microtubule-disrupting agent, MMAE, using Seattle Genetics’ proprietary linker technology. Enfortumab vedotin targets Nectin-4, a cell adhesion molecule that is expressed on many solid tumors, and that has been identified as an ADC target by Astellas. A Biologics License Application is currently under review by the U.S. Food and Drug Administration (FDA) for the treatment of patients with locally advanced or metastatic urothelial cancer who have received a PD-1/PD-L1 inhibitor and who have received a platinum-containing chemotherapy before (neoadjuvant) or after (adjuvant) surgery or in a locally advanced or metastatic setting. Enfortumab vedotin is being co-developed by Seattle Genetics and Astellas Pharma Inc.
The safety and efficacy of enfortumab vedotin are under investigation and have not been established. There is no guarantee that the agent will receive regulatory approval or become commercially available for the uses being investigated.
About Tisotumab Vedotin
Tisotumab vedotin is an antibody-drug conjugate (ADC) composed of Genmab’s human antibody that binds to Tissue Factor and Seattle Genetics’ ADC technology that utilizes a cleavable linker and the microtubule disrupting agent monomethyl auristatin E (MMAE). In cancer biology, Tissue Factor is a protein involved in tumor signaling and angiogenesis. The Tissue Factor antigen target is overexpressed in the vast majority of patients with cervical cancer and in many other solid tumors, including ovarian, lung, pancreatic, colorectal and head and neck. Based on its high expression on many solid tumors and its rapid internalization, Tissue Factor was selected as a target for an ADC approach. Tisotumab vedotin is being co-developed by Seattle Genetics and Genmab.
About Tucatinib
Tucatinib is an investigational, orally bioavailable, potent tyrosine kinase inhibitor that is highly selective for HER2 without significant inhibition of EGFR. Inhibition of EGFR has been associated with significant toxicities, including skin rash and diarrhea. Tucatinib has shown activity as a single agent and in combination with both chemotherapy and other HER2 directed agents such as trastuzumab.1 Studies of tucatinib in these combinations have shown activity both systemically and in brain metastases. 1 HER2 is a growth factor receptor that is overexpressed in multiple cancers, including breast, ovarian and gastric cancers. HER2 mediates cell growth, differentiation and survival. Tumors that overexpress HER2 are more aggressive and historically have been associated with poor overall survival compared with HER2-negative cancers. Tucatinib has been granted orphan drug designation by the FDA for the treatment of breast cancer patients with brain metastases.
