EISAI TO PRESENT PRECLINICAL AND CLINICAL RESEARCH ON ERIBULIN AT THE 2022 SAN ANTONIO BREAST CANCER SYMPOSIUM

¾«¶«Ó°Òµ. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) announced today that new study results on its in-house discovered and developed anticancer agent eribulin mesylate (HALAVEN®, “eribulin”) will be presented during the 2022 San Antonio Breast Cancer Symposium (SABCS), which is taking place virtually and in-person in San Antonio, Texas from December 6-10.

 

¾«¶«Ó°Òµwill present five eribulin-related abstracts, including a post hoc subgroup analysis from two pivotal Phase 3 studies (EMBRACE and Study 301), as well as:

-    Real world use of eribulin following treatment with a P13K inhibitor, mostly in people with Hormone Receptor (HR)-positive/HER2-negative metastatic breast cancer.

-    Preclinical data exploring a liposomal formulation of eribulin, in a Phase 1 expansion cohort for breast cancer, versus eribulin at the same dose, in patient-derived breast cancer xenografts.

 

"We continue to relentlessly pursue research that provides useful insights for people living with breast cancer,” said Dr. Takashi Owa, Chief Scientific Officer, Senior Vice President, ¾«¶«Ó°Òµ. “A big part of this commitment is the ongoing sharing of our preclinical and clinical data with eribulin.”

 

This release discusses investigational compounds and investigational uses for FDA-approved products. It is not intended to convey conclusions about efficacy and safety. There is no guarantee that any investigational compounds or investigational uses of FDA-approved products will successfully complete clinical development or gain FDA approval.

1. Eisais Focus on Cancer

¾«¶«Ó°Òµfocuses on the development of anticancer drugs, targeting the tumor microenvironment (with experience and knowledge from existing in-house discovered compounds) and the driver gene mutation and aberrant splicing (leveraging RNA Splicing Platform) as areas (Ricchi) where real patient needs are still unmet, and where ¾«¶«Ó°Òµcan aim to become a frontrunner in oncology. ¾«¶«Ó°Òµaspires to discover innovative new drugs with new targets and mechanisms of action from these Ricchi, with the aim of contributing to the cure of cancers.
