Elsalys Biotech SAS, a 2013 spinout from Transgene SA, achieved a significant milestone with the finding that lead candidate inolimomab (Leukotac) showed clinical benefit during long-term follow-up of up to 8.5 years in individuals treated in the phase III study in acute steroid-resistant graft-vs.-host disease (SR-aGVHD). The positive overall survival (OS) outcome in the long-term analysis positions the Lyon, France-based company for a regulatory filing in the EU next year and puts discussions with commercial partners on the front burner – admirable achievements for a company of just 16 employees that's raised less than €20 million (US$22.8 million).
