London: GSK subsidiary, TESARO, Inc., has initiated litigation against AnaptysBio, Inc. in the Delaware Chancery Court. This action contends that recent conduct by AnaptysBio is in material breach of the existing license agreement with TESARO regarding the oncology treatment Jemperli (dostarlimab).
The breach entitles TESARO to terminate the current license agreement, obtain a perpetual and irrevocable license to dostarlimab, and to reduce the royalties and milestone payments due by TESARO to AnaptysBio by 50%.
