LONDON – A year on from delivering positive phase IIb data, Oculis SA has raised $57 million in an oversubscribed series C, to take OCS-01, a topical nanoparticle formulation of dexamethasone, through two phase III trials.

Lexington, Mass.-based Aldeyra Therapeutics Inc.’s phase III win in the study called Invigorate with reproxalap for allergic conjunctivitis (AC) restarted speculation about odds of the drug, a small-molecule, immune-modulating covalent inhibitor of reactive aldehyde species (RASP), to treat dry eye disease (DED). “I do think there is potential read-through,” CEO Todd Brady said, especially with regard to the redness endpoint. A six-week safety study necessary before going to the FDA has not yet started, he told investors during a conference call. “That will require some discussions with the FDA, but I do not think, given the length of the trial, the safety study would impair our guidance of potentially filing NDAs by the end of this year.”

Stuart Therapeutics Inc., a company developing peptide therapeutics for ophthalmic disease, has completed an $11 million series A financing led by Infocus Capital Partners, an ophthalmology-focused life sciences venture capital fund, with significant participation by the Wisconsin Alumni Research Foundation, Mimo Capital and Biobrit.
