Sotyktu (deucravacitinib), the tyrosine kinase 2 (TYK2) inhibitor for psoriasis from Bristol Myers Squibb Co., is “a good first-in-class” drug, said Nimbus Therapeutics LLC CEO Jeb Keiper, but his firm may have the best in class, ready for phase III trials. Takeda Pharmaceutical Co. Ltd. apparently believes so. The company has agreed to pay $4 billion up front and pledge as much as $2 billion more in potential milestone payments to acquire Nimbus’s wholly owned subsidiary, Nimbus Lakshmi Inc., thereby bringing aboard the TYK2 prospect called NDI-034858.
