Astellas is presenting a record number of abstracts at ASCO (Free ASCO Whitepaper), including data for gilteritinib in acute myeloid leukemia, enfortumab vedotin in urothelial cancer, and IMAB362 from the recently acquired Ganymed. A number of XTANDI (enzalutamide) abstracts accepted for presentation also speak to the comprehensive clinical trial program in metastatic CRPC and other prostate cancer populations. In just over a decade, Astellas has built a leadership position and substantial Oncology pipeline through a thoughtful blend of investments in organic R&D, strategic business development and strong collaborative partnerships with some of the most renowned institutions around the world.
"We are thrilled to announce our largest presence to date at this year’s ASCO (Free ASCO Whitepaper) meeting," said Steven Benner, M.D., senior vice president and global therapeutic area head, oncology development, Astellas. "We believe these data reflect significant progress in our pursuit to create innovative treatment options for some of the most difficult-to-treat cancers and further underscore our ongoing commitment to becoming a world-class oncology company focusing on patients with cancer."
Additionally, the Company announced today the joint decision with Pfizer to discontinue the planned ENDEAR trial (A Phase III, Randomized, International Study Comparing the Efficacy and Safety of Enzalutamide in Combination With Paclitaxel Chemotherapy or as Monotherapy Versus Placebo With Paclitaxel in Patients With Advanced, Diagnostic-Positive, Triple-Negative Breast Cancer); no patients were ever enrolled in the trial. The companies have also decided that based on the enzalutamide data from the Phase 2 HER2+ and ER/PR+ breast cancer studies, there will not be follow-on Phase 3 studies at this time.
About XTANDI (enzalutamide) capsules
XTANDI (enzalutamide) is an androgen receptor inhibitor that blocks multiple steps in the androgen receptor signaling pathway within the tumor cell. In preclinical studies, enzalutamide has been shown to competitively inhibit androgen binding to androgen receptors, and inhibit androgen receptor nuclear translocation and interaction with DNA. The clinical significance of this mechanism of action (MOA) is unknown.
XTANDI is approved by the U.S. Food and Drug Administration for the treatment of patients with metastatic castration-resistant prostate cancer (mCRPC). Enzalutamide is not approved for use in patients with breast cancer.
