Revenue of $9.7 million this quarter represented growth from the previous year's $8.5 million, primarily fueled by the collaboration with Astellas, indicating strong partnerships are paying off.
Restructuring for Growth
In response to dynamic market conditions, Sutro recently initiated a corporate restructuring aimed at optimizing its operational capabilities. By reallocating resources towards the most promising programs, the company expects to enhance efficiency and focus on collaboration opportunities that align with its long-term objectives.
