Volatility is currently expanding

REGENXBIO stock plunges 25% after the FDA places a clinical hold on RGX-121 for MPS II, following asymptomatic spine MRI findings in five participants.

Regenxbio is rated a 'risky buy' due to high volatility, regulatory setbacks, and significant near-term catalysts. RGNX faces a clinical hold on RGX-121 for Hunter Syndrome, complicating milestone payments and royalty streams, but maintains sufficient cash runway into Q4 2027. Pivotal data for the AbbVie-partnered eye disease program and BLA submission for RGX-202 in DMD represent major binary catalysts by year-end and 2027.
