Ollin Biosciences has secured $330 million in venture financing to advance pivotal trials of its experimental eye drug, a direct challenger to Roche's Vabysmo. The funding is among the year's largest biotech rounds and follows a head-to-head study showing the therapy has certain advantages over the established blockbuster.

The company's drug, licensed from a China-based developer, targets wet age-related macular degeneration and diabetic macular edema. Data from the comparative trial indicated benefits over Vabysmo, though specific efficacy numbers and safety details were not disclosed in the announcement.

Ollin plans to use the capital to fund pivotal-stage testing. The regulatory pathway for the therapy remains under development, with no specific FDA or EMA submission dates provided. A timeline to market has not been established.

The $330 million injection positions Ollin to compete in the $12 billion-plus retinal disease market currently dominated by Roche and Regeneron. The funding signals strong investor confidence in the therapy's potential to capture market share from Vabysmo, which generated nearly $3 billion in 2023 sales.

A key caveat: the data supporting the drug's reported advantages have not been published or peer-reviewed, and the assets are licensed from an outside developer, introducing execution risk. The therapy must still prove itself in larger, registrational trials before reaching patients.
