Future After Wind Down

On Monday, Galapagos said that the wind-down of the cell therapy activities will position it for longer-term growth. The company will continue to manage its non-cell therapy programs and evaluate all strategic alternatives for GLPG3667, an investigational, oral, selective inhibitor of tyrosine kinase 2, to accelerate its development in dermatomyositis and potentially other severe auto-immune indications, the company said.

The company will also consider resuming the partnering process for the drug, it said. Galapagos also added that it will continue to maintain its presence at its headquarters in Belgium as well as its hubs in Chicago and San Francisco.
