Pharmaceutical Deal-making news last week featured US pharma giant Merck & Co further expanding its cytokines portfolio, signing a license and research collaboration with Synthekine on novel therapeutics for autoimmune diseases. Also, Swiss giant Novartis extended its interest in the area of protein degraders, announcing an up to $1.3 billion deal with Dunad Therapeutics. Long rumored and finally announced, Novartis said it has agreed to sell back to Roche the 33% of voting shares it has been holding in its Swiss rival for 20 years or so.
