Bayer’s $2.45 Billion Perfuse Deal Puts Eye-Drug Pipeline Back in Focus
Bayer agreed to acquire Perfuse Therapeutics for up to $2.45 billion, including $300 million upfront, to gain access to a mid-stage eye-disease drug, PER-001. Eylea, Bayer’s top-selling eye drug, saw 2025 sales fall 5.9% to €3.11 billion amid generic competition. The deal awaits antitrust and shareholder approval. PER-001 is in Phase II trials for glaucoma and diabetic retinopathy.
