With the U.S. FDA go-ahead granted June 26 for Viridian Therapeutics Inc.’s IGF-1R antagonist Lumvoa (veligrotug-vvze, or “veli”) as a new thyroid eye disease (TED) therapy – due to launch immediately, the company said – Wall Street will be watching near-term payer dynamics. The drug is set to take on similarly targeted Tepezza (teprotumumab-trbw), owned by Amgen Inc. and approved in January 2020 to treat TED.

Viridian Therapeutics Inc.’s U.S. FDA clearance of Lumvoa (veligrotug-vvze) to treat thyroid eye disease (TED) includes labeling for chronic as well as active forms, and fewer infusions – plus fast, durable effects – should give the IGF-1R antagonist leverage in competing with similarly targeted TED drug Tepezza (teprotumumab-trbw), owned by Amgen Inc. and approved in January 2020.

The oversubscribed $330 million series B round secured by Ollin Biosciences Inc. marks more than another large venture round in ophthalmology. It also highlights an emerging biotech financing model in which Chinese pharma companies discover and clinically validate promising drugs before handing global development to well-capitalized U.S. startups backed by blue-chip venture investors.
