BioMarin Discontinues Voxzogo Trials Amid Safety Concerns
- Trial Discontinuation: BioMarin announced the discontinuation of dosing and enrollment in its phase 2 trials for Voxzogo in Turner syndrome, SHOX deficiency, and ACAN deficiency due to multiple slipped capital femoral epiphysis (SCFE) events, indicating potential safety concerns that could impact future drug development strategies.
- Safety Profile Maintained: Although no SCFE events were observed in BioMarin's other phase 2 trials and none in over 5,000 children treated with Voxzogo, the occurrence of these events may still undermine investor confidence in the company's products, potentially affecting stock performance.
- Continued Trials: BioMarin stated that the Canopy phase 2 trials for children with Noonan syndrome and idiopathic short stature (ISS) without ACAN deficiency will proceed as planned, suggesting that the company still sees potential in Voxzogo for certain indications, which may support future market performance.
- Stock Price Reaction: Following this announcement, BioMarin's shares fell 4.6% to $55.80 in premarket trading, reflecting the market's negative reaction to the trial discontinuation, which could impact its future financing and R&D capabilities.
