TOKYO and MUNICH and BASKING RIDGE, New Jersey, March 28, 2019 /PRNewswire/ -- Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) announced today that it has entered into a global development and commercialization agreement with AstraZeneca for Daiichi Sankyo's lead antibody drug conjugate (ADC), [fam-] trastuzumab deruxtecan (DS-8201), currently in pivotal development for multiple HER2 expressing cancers including breast and gastric cancer, and additional development in non-small cell lung and colorectal cancer.

Daiichi Sankyo and AstraZeneca will jointly develop and commercialize [fam-] trastuzumab deruxtecan as a monotherapy or a combination therapy worldwide, except in Japan where Daiichi Sankyo will maintain exclusive rights. Daiichi Sankyo will be solely responsible for manufacturing and the supply of [fam-] trastuzumab deruxtecan.

As announced separately by Daiichi Sankyo, a Biologics License Application (BLA) submission to U.S. FDA for [fam-] trastuzumab deruxtecan in HER2 positive metastatic breast cancer previously treated with ado trastuzumab emtansine (T-DM1) will be accelerated to the first half of fiscal year 2019.

It is designed to target and deliver chemotherapy inside cancer cells and reduce systemic exposure to the cytotoxic payload compared to the way chemotherapy is commonly delivered.
