EXTON, PA, USA I April 9, 2018 I Morphotek®, Inc., a subsidiary of Eisai Inc., announced today that it licensed its eribulin-linker payload to Bliss Biopharmaceutical Co., Ltd. (BlissBio) of China. The licensing agreement grants BlissBio the exclusive right to use the eribulin-linker payload to develop a therapeutic ADC against an undisclosed oncology target for the China market. The licensing agreement includes an upfront payment, milestones and sales royalty payments, which are undisclosed. BlissBio has an exclusivity option to expand the territory beyond China to the global market and to develop therapeutic ADCs to two additional undisclosed oncology targets.
Morphotek's ADC Services offer third parties the opportunity to license the proprietary eribulin-linker payload to develop investigational ADCs using either Morphotek's REsidue-SPEcific Conjugation Technology (RESPECT™) or an alternative approach to conjugation. The eribulin-linker payload consists of a cytotoxic agent, eribulin, modified by a chemical linker to facilitate optimal conjugation. Eribulin's anti-tumor activity is mediated by the inhibition of microtubule elongation and mitotic spindle formation, resulting in apoptosis. Eribulin mesylate, marketed as Halaven®, is approved in the U.S. for the treatment of patients with metastatic breast cancer who have previously received at least two chemotherapeutic regimens for metastatic disease, including an anthracycline and a taxane in either the adjuvant or metastatic setting.
*The ADCs described herein are investigational, as efficacy and safety have not been established. There is no guarantee that the ADCs will be available commercially.

About Halaven® (eribulin mesylate) Injection
Halaven® (eribulin mesylate) is a microtubule dynamics inhibitor indicated for the treatment of patients with:
- Metastatic breast cancer who have previously received at least two chemotherapeutic regimens for the treatment of metastatic disease. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting.
- Unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen.
Discovered and developed by Eisai, eribulin is a synthetic analog of halichondrin B, a natural product that was isolated from the marine sponge Halichondria okadai. First in the halichondrin class, Halaven is a microtubule dynamics inhibitor. Eribulin is believed to work primarily via a tubulin-based mechanism that causes prolonged and irreversible mitotic blockage, ultimately leading to apoptotic cell death. Additionally, in preclinical studies of human breast cancer, eribulin demonstrated complex effects on the tumor biology of surviving cancer cells, including increases in vascular perfusion resulting in reduced tumor hypoxia, and changes in the expression of genes in tumor specimens associated with a change in phenotype, promoting the epithelial phenotype, opposing the mesenchymal phenotype. Eribulin has also been shown to decrease the migration and invasiveness of human breast cancer cells. Halaven is approved in approximately 60 countries worldwide.
