"The research presented at ASCO (Free ASCO Whitepaper) reflects our intense focus on how we are continuing to grow the breadth and utility of our oncology portfolio and pipeline for the oncology community and patients with cancer, particularly those with advanced disease," said Ahsan Arozullah, MD, MPH, Senior Vice President, Head of Oncology Development, Astellas. "Across our clinical development programs, these data add to the growing body of evidence and support our efforts to identify ways we can impact the course of disease, and redefine what is possible for patients who need it most."
Highlights at the 2023 ASCO (Free ASCO Whitepaper) Annual Meeting include:
A rapid abstract update presentation of investigational data from the Phase 3 GLOW clinical trial, evaluating the efficacy and safety of zolbetuximab – an investigational first-in-class Claudin-18.2 (CLDN18.2) targeted monoclonal antibody – in combination with CAPOX (a combination chemotherapy regimen that includes capecitabine and oxaliplatin) for the first-line treatment of patients with CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or GEJ adenocarcinoma.
The first clinical data from the Phase 1 EV-104 study evaluating intravesical administration of enfortumab vedotin, an antibody-drug conjugate developed in partnership with Seagen, in patients with non-muscle invasive bladder cancer.
The first clinical data from the Phase 2 EV-202 study evaluating enfortumab vedotin monotherapy in previously treated advanced head & neck cancers.
"For the first time, we will present clinical data at ASCO (Free ASCO Whitepaper) investigating the potential of enfortumab vedotin as monotherapy in patients with previously treated advanced head and neck cancers, who have ongoing and unmet therapeutic needs," said Erhan Berrak, MD, Vice President, Medical Affairs, Oncology Therapeutic Area Head, Astellas. "Additionally, Astellas is pleased to share investigational data at ASCO (Free ASCO Whitepaper) that demonstrate continued progress for our zolbetuximab clinical development program in locally advanced or metastatic gastric and GEJ cancers, which have limited effective treatment options."
