July 2 (Reuters) – Celea Therapeutics, linked to PureTech Health, on Thursday completed a $180 million financing round for a late-stage trial ​of its lung disease drug, deupirfenidone, ‌in patients with idiopathic pulmonary fibrosis (IPF).

• Celea expects to start a head-to-head trial in the third quarter, it said in a statement on Thursday.

• As ‌well ​as PureTech, RA Capital, Leaps ⁠by Bayer, a ⁠large, U.S.-based healthcare-focused fund, and a sovereign wealth fund, participated in the round.

• Celea and the transferred assets were valued at $100 ​million before the round and $302.5 million after it on a fully diluted basis.

• PureTech ⁠contributed $30 million to the ⁠financing and is reserving $70 million to ​support Celea in the future.

• After the financing, ​PureTech will hold a 35.4% stake in ‌the biotech and is entitled to receive tiered royalties on annual net sales of Celea’s products using deupirfenidone technology.

• PureTech is ⁠also eligible for up to $190 million in aggregate milestone payments.

• Deupirfenidone is an experimental drug designed to ⁠slow or ‌prevent lung scarring with improved ⁠tolerability, potentially making patients more likely to ​stick ‌to their treatments than with existing ​medications.

• Idiopathic ⁠pulmonary fibrosis is a disease of unknown cause where the lung tissue becomes damaged and scarred, making it increasingly difficult to breathe.
