- FDA Clinical Hold: REGENXBIO's gene therapy RGX-111 for Hurler syndrome faces a clinical hold from the FDA due to a tumor case in a trial participant, causing shares to plummet approximately 30% in premarket trading, highlighting market sensitivity to FDA unpredictability.
- Analyst Perspectives: Clear Street analyst Bill Maughan reiterated a ‘Buy’ rating with a $50 price target, noting that the causality between RGX-111 and the tumor remains unestablished, and the patient was asymptomatic, suggesting the market's reaction may be an overreaction.
- Market Reaction: Despite the stock's decline post-announcement, Leerink views the selloff as excessive, believing that the financial impact of Hunter/Hurler syndrome on the company's fundamental value is modest, thus presenting a buying opportunity while maintaining an ‘Outperform’ rating.
- Future Outlook: Stifel also reaffirmed a ‘Buy’ rating with a $45 price target, expecting a delay in FDA approval for RGX-121, yet maintains that the risk-benefit profile for other gene therapies remains favorable.
