IDEAYA Biosciences (IDYA) stock surged 31.15% during pre-market trading on Monday following the announcement of positive clinical trial results for its experimental cancer treatment.
The oncology company reported that its Phase 2/3 registrational trial, OptimUM-02, evaluating darovasertib in combination with crizotinib for metastatic uveal melanoma, met its primary endpoint. The combination therapy showed a statistically significant improvement in median progression-free survival, extending it to 6.9 months compared to 3.1 months for the investigator's choice of therapy.
Based on these results, IDEAYA Biosciences plans to submit a New Drug Application to the U.S. Food and Drug Administration in the second half of 2026, aiming for accelerated approval of the treatment for this rare and aggressive form of eye cancer.
