The Roche group has staked out fibrotic disease as a growth area with the planned acquisition of Promedior Inc of Lexington, Massachusetts, US for up to $1.39 billion. Promedior has a product for idiopathic pulmonary fibrosis (IPF) poised to enter Phase 3 which has shown an ability to slow the decline of lung function in a randomised Phase 2 study of patients with the disease. The drug, PRM-151, is a recombinant form of the human pentraxin-2 protein, reportedly with a potential to treat a wide range of systemic fibrotic diseases.
