Astellas Showcases Scientific Advancements Across its Oncology Portfolio at 2024 ASCO Annual Meeting

16 abstracts feature new data and post-hoc analyses of pivotal trials across several types of hard-to-treat cancers

TOKYO, May 13, 2024 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, "Astellas") will share new research from across its innovative portfolio of approved and investigational cancer therapies during the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting from May 31 - June 4. A total of 16 abstracts will be presented, including new data from pivotal trials supporting ongoing regulatory reviews. The volume of data being presented by Astellas reinforces its commitment to changing the course of cancer treatment through targeted therapies for hard-to-treat cancers like prostate, urothelial, and gastric/gastroesophageal junction (GEJ) cancers.

Tadaaki Taniguchi, MD, PhD, Chief Medical Officer, Astellas
"The data at ASCO demonstrate the strength and breadth of our growing oncology portfolio and provide new insights into our transformative therapies for patients living with some of the most devastating cancers. Recent regulatory achievements mean our oncology medicines are reaching more patients than ever worldwide, and we are continuing to pursue novel targets and invest in research to improve overall survival and raise quality of life."

Highlights at the 2024 ASCO Annual Meeting include:

    --  Further data from the Phase 3 EV-302 trial evaluating enfortumab vedotin
        in combination with pembrolizumab versus chemotherapy in previously
        untreated locally advanced or metastatic urothelial carcinoma (la/mUC),
        including data in cisplatin-eligible and cisplatin-ineligible
        populations. These results support the combination as a landmark
        advancement in the care of patients with la/mUC, regardless of cisplatin
        eligibility, and serve as the basis of ongoing regulatory reviews by the
        European Medicines Agency's (EMA) Committee for Medicinal Products for
        Human Use (CHMP), Japan's Ministry of Health, Labour and Welfare (MHLW),
        and the China National Medical Products Administration (NMPA).
    --  Final overall survival (OS) results from the Phase 3 SPOTLIGHT study,
        evaluating the efficacy and safety of zolbetuximab - a first-in-class
        claudin (CLDN) 18.2-targeted monoclonal antibody approved by Japan's
        MLHW and currently in review by multiple regulatory authorities for
        approval worldwide. In this abstract, zolbetuximab is evaluated in
        combination with mFOLFOX6 (a combination chemotherapy regimen that
        includes oxaliplatin, leucovorin, and fluorouracil) for the first-line
        treatment of patients with CLDN18.2 positive, human epidermal growth
        factor receptor 2 (HER2)-negative, locally advanced unresectable or
        metastatic gastric or GEJ adenocarcinoma. These results underpin the
        strength of the zolbetuximab clinical data supporting the pursuit of
        regulatory approvals worldwide.
    --  Two new post-hoc analyses of the Phase 3 EMBARK trial, which evaluated
        enzalutamide plus leuprolide, placebo plus leuprolide, and enzalutamide
        (single agent) in patients with nonmetastatic hormone- (or castration-)
        sensitive prostate cancer (nmHSPC or nmCSPC) with high-risk biochemical
        recurrence (BCR), including an oral presentation on the impact of
        treatment suspension on health-related quality of life and a poster
        presentation on sexual activity patient-reported outcomes.
