Complaint Allegations
A previously filed federal securities class action complaint alleges that defendants made materially false and/or misleading statements and/or failed to disclose that:
- REGENXBIO’s positive statements concerning the anticipated success of RGX-111’s Phase I/II clinical trial emphasized favorable biomarker, safety, and neurodevelopmental data while allegedly omitting material safety concerns;
- Defendants allegedly concealed or minimized serious safety risks associated with the RGX-111 study, including the potential for a central nervous system neoplasm; and
- As a result, defendants’ statements concerning REGENXBIO’s business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times.
The complaint further alleges that, on January 28, 2026, REGENXBIO announced that the FDA had placed RGX-111 on clinical hold after an intraventricular central nervous system tumor was identified in a participant treated in the RGX-111 Phase I/II study. REGENXBIO’s stock price fell from $13.41 per share on January 27, 2026, to $11.01 per share on January 28, 2026, a decline of approximately 17.8%.
