Privately held Amphista Therapeutics Ltd. has cut massive deals with two biopharma giants, Merck KGaA and Bristol Myers Squibb Co. (BMS), that together could bring the company up to $2.25 billion. The companies will use Amphista’s Eclipsys platform to generate protein degrader-based therapeutics. Merck is looking to discover and develop small-molecule protein degraders for treating cancer and immune disease. Indications in the BMS deal were not announced.
