A venture capital syndicate has mobilised $141 million in Series B financing for an Italian biotech which is developing two gene therapies for retinal disorders. The company, AAVantgarde Bio Srl of Milan, is developing therapies for Stargardt disease and retinitis pigmentosa due to Usher syndrome type 1B. Both conditions are inherited retinal diseases for which there are no approved therapies. AAVantgarde is a spin-off of the Telethon Institute for Genetics and Medicine, an international research institute based in Naples.
