Analysis
Ligand Pharmaceuticals has terminated its Master License Agreement for the TR-Beta Program, including key assets VK2809 and VK0214, with Viking Therapeutics. Ligand asserts that Viking materially breached its obligation to use commercially reasonable efforts in developing and commercializing the program. This action allows Ligand to regain all licenses and obtain a royalty-bearing license from Viking for any related intellectual property. However, Viking is disputing Ligand's right to terminate, introducing potential legal uncertainty. This move reflects Ligand's active portfolio management, following its recent $739 million acquisition of XOMA Royalty Corporation, and could be an effort to re-evaluate or take direct control of underperforming assets.
