May 6 (Reuters) – Bayer said on Wednesday that it will ​buy biopharmaceutical ‌company Perfuse Therapeutics to complement its ophthalmology pipeline.

The deal has a ‌potential ​value of ⁠up to $2.45 billion, ⁠the company said in a statement, with a $300 million upfront ​payment and additional development, regulatory ⁠and commercial ⁠milestone payments based ​on success criteria.

The acquisition will ​become ‌effective after receiving ​the necessary ⁠antitrust clearances and Perfuse stockholder approvals, Bayer said.
