LEO Pharma to buy U.S. drug developer Replay for $50 million upfront

Industry:    2026-05-02

Danish drugmaker LEO Pharma said on Thursday it had agreed to buy U.S. drug developer Replay for $50 million upfront, adding ​an experimental treatment platform for rare genetic skin diseases ‌to its dermatology business.

The deal includes milestone payments and tiered single-digit royalties, though the company did not disclose the size of the milestones.

Replay’s virus design and manufacturing ​team would join LEO Pharma dermatology portfolio as part of ​the acquisition, the company added.

“On top of all the ⁠pipelines that we have now, we’re entering the promise of gene ​therapy,” CEO Christophe Bourdon told Reuters.

Replay is developing an experimental gene ​therapy applied to the skin as a gel, using a modified herpes virus to carry genetic material into skin cells.

Its lead candidate targets dystrophic epidermolysis ​bullosa, a rare blistering disease, and remains in preclinical testing.

The deal ​pushes LEO Pharma deeper into rare skin diseases, building on its Boehringer Ingelheim ‌partnership ⁠for Spevigo and a DEBRA research tie-up targeting epidermolysis bullosa, a rare condition that leaves skin fragile and easily blistered.

“There is a preclinical proof of concept that makes us believe that we can ​really unfold it ​into several ⁠diseases,” Chief Scientific Officer Jacob Pontoppidan Thyssen told Reuters.

The purchase comes as the company prepares for a ​possible stock-market listing, making growth deals more important ​as it ⁠tries to show investors where future sales could come from.

After a leadership and organizational reshuffle four years ago, LEO Pharma has been sharpening ⁠its ​focus, but stronger results have given ​it more room to do deals that add to its skin-disease business.
