Genmab Announces Decision in Arbitration Appeal under License Agreement with Janssen

​

Company Announcement

COPENHAGEN, Denmark; January 23, 2024 – Genmab A/S (Nasdaq: GMAB) announced today that the appeal arbitrator in its second arbitration arising under its license agreement with Janssen Biotech, Inc. (Janssen) for daratumumab has denied Genmab’s appeal. As a result, the dismissal of Genmab’s claims in the second arbitration is now concluded. Genmab had appealed the tribunal’s two-to-one decision dismissing Genmab’s claims on the basis that the claims should have been brought in the prior arbitration between Genmab and Janssen.

Genmab’s claims were based upon its position that the subcutaneous formulation of daratumumab (SC daratumumab, marketed as DARZALEX FASPRO^® in the United States) is a new licensed product under the license agreement. The claims included both a claim for milestone payments with respect to SC daratumumab and a claim for a new 13-year royalty term, on a country-by-country basis, from the date of the first commercial sale of SC daratumumab in each such country. The decision in the arbitration appeal will have no effect on Genmab’s upcoming financial guidance for 2024.
