(TSE: 4503, President and CEO: Kenji Yasukawa, Ph.D., "Astellas") will share new research during the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting from June 3-7 and the European Hematology Association (EHA) 2022 Hybrid Congress from June 9-12. A total of 13 abstracts from the company's expanding portfolio of approved and investigational therapies will be presented across both meetings, underscoring the company's commitment to advancing treatment options for advanced and rare cancers, including prostate, pancreatic and urothelial cancer, as well as acute myeloid leukemia (AML).

"While a robust Phase 3 clinical trial program in gastric/gastroesophageal junction cancer for our investigational therapy zolbetuximab is well underway, the ASCO Annual Meeting will include the first trial-in-progress presentation from our expanded Phase 2 clinical trial in Claudin 18.2-positive pancreatic cancer," said Ahsan Arozullah, M.D., M.P.H., Senior Vice President and Head of Development Therapeutic Areas, Astellas. "The progress of these clinical studies reflects our enthusiasm to continue investigating the potential to benefit patients by targeting the emerging Claudin 18.2 biomarker."

"At Astellas, our mission is to not only advance innovative science, but to create value for patients and the oncology community," said Erhan Berrak, M.D., Vice President of Global Medical Affairs, Oncology, Astellas. "Our advanced prostate cancer data at ASCO, which range from new analyses of our ARCHES pivotal trial in metastatic hormone-sensitive prostate cancer to data on patient preferences and prescriber treatment decisions, will help inform discussions between patients and providers about novel hormone therapies." 

Highlights at the 2022 ASCO Annual Meeting include:

• An overview of the expanded Phase 2 open-label, randomized study of zolbetuximab in combination with nab-paclitaxel and gemcitabine as an investigational first-line treatment for patients with Claudin 18.2-positive metastatic pancreatic cancer

• Four post-hoc analyses from the Phase 3 ARCHES study, which compared enzalutamide plus androgen deprivation therapy (ADT) versus placebo plus ADT in men with metastatic hormone-sensitive prostate cancer (mHSPC)

Highlights at the EHA 2022 Hybrid Congress include:

• Encore data from the COMMODORE Phase 3 confirmatory study of gilteritinib versus salvage chemotherapy in FLT3 mutation-positive relapsed or refractory AML in China and other countries
