The ASCO data presentation in June is a key near-term catalyst for OBX-115; traders should monitor for clinical efficacy signals in the melanoma data, which could drive valuation for the combined entity post-close. Galera shareholders face significant dilution and should assess whether the CVR and minimal equity stake justify holding through closing.
