The completion of patient recruitment removes a key binary risk and de-risks the timeline to a potential blockbuster product. Traders should watch for top-line data in mid-2027 and any partnership or licensing announcements before then. The strong insider buying and RMAT designation support a positive outlook, but the long wait for data means near-term volatility may be limited.
