Fenwick Represents Seagen in Its Worldwide License and Co-Development Agreement with RemeGen

Fenwick represented Seagen Inc. (Nasdaq: SGEN), a world leader and pioneer in antibody-drug conjugate (ADC) therapies, in its license and co-development agreement with RemeGen Co., Ltd. (9995.HK), a leading innovative biopharmaceutical company in China. The companies have entered into an exclusive worldwide licensing agreement to develop and commercialize disitamab vedotin, a novel ADC that selectively delivers the anti-cancer agent monomethyl auristatin E (MMAE) into HER2-expressing tumor cells.

Under the terms of the agreement, Seagen will make a $200 million upfront payment to exclusively license rights to disitamab vedotin for global development and commercialization, outside of RemeGen’s territory. RemeGen will retain development and commercialization rights for Asia, excluding Japan and Singapore. Seagen will lead global development and RemeGen will fund and operationalize the portion of global clinical trials attributable to its territory. RemeGen will also be responsible for all clinical development and regulatory submissions specific to its territory.

Seagen will pay RemeGen up to $2.4 billion in potential total milestone payments based upon the achievement of specified development, regulatory and commercialization goals across multiple indications and products. RemeGen will be entitled to a tiered, high single digit to mid-teen percentage royalty based on net sales of disitamab vedotin in Seagen’s territory.

More information about the collaborations can be obtained from SeaGen’s announcement.

The Fenwick transaction team was led by life sciences partner Stefano Quintini and counsel Amy Manning.
