BOTHELL, Wash.--(BUSINESS WIRE)--Seagen Inc. (Nasdaq: SGEN) today announced the presentation of 17 abstracts at the upcoming 2023 American Society of Clinical Oncology (ASCO) Annual Meeting taking place June 2-6, 2023, in Chicago. Data will be presented across Seagen's portfolio of approved medicines and pipeline agents in a range of cancer types and in earlier lines of therapy.
'Seagen has worked towards revolutionizing cancer care for 25 years by linking scientific innovation to meaningful impacts in patients\u2019 lives'
Seagen has worked towards revolutionizing cancer care for 25 years by linking scientific innovation to meaningful impacts in patients’ lives,” said Roger Dansey, M.D., President, Research and Development and Chief Medical Officer at Seagen. “Our data presented at ASCO demonstrate continued progress in our efforts to discover and develop transformative medicines.”
Highlights include new data from a robust clinical development program in bladder cancer with trials across multiple lines of treatment and into earlier stages of disease for muscle-invasive and non-muscle invasive forms of bladder cancer. Long-term follow-up data from a clinical trial of PADCEV® (enfortumab vedotin-ejfv) (EV-103 dose-escalation and Cohort A) will be featured in an oral presentation on Monday, June 5. The EV-103 dose-escalation/Cohort A study is evaluating PADCEV, developed in partnership with Astellas, in combination with Merck’s anti-PD-1 therapy KEYTRUDA® (pembrolizumab) as first-line treatment in patients with locally advanced or metastatic urothelial carcinoma who are ineligible to receive cisplatin-based chemotherapy. Merck is known as MSD outside the United States and Canada.
Updated Phase 1 data will be presented for SGN-B6A, a wholly-owned, first-in-class vedotin ADC directed to integrin beta-6, a novel target that is highly expressed in multiple solid tumors.
Additionally, initial data will be presented from studies evaluating Seagen’s approved medicines in potential new cancer types. Data from a Phase 2 basket study of TUKYSA® (tucatinib) and trastuzumab in previously treated HER2-positive metastatic biliary tract cancerHER2-positive metastatic biliary tract cancer will be featured in an oral presentation on Friday, June 2.
Key data presentations for Seagen include:
