REGENXBIO (Nasdaq: RGNX) announced the FDA issued a Complete Response Letter (CRL) on February 7, 2026 for its BLA for RGX-121 (clemidsogene lanparvovec) for Mucopolysaccharidosis II (MPS II). The CRL cited concerns about defining the neuronopathic population, comparability of the external natural-history control, and the CSF HS D2S6 surrogate endpoint.
REGENXBIO said the FDA agreed to the study protocol in principle, the company will request a Type A meeting, pursue paths outlined in the CRL, and aims to resubmit the BLA after providing additional analyses and longer-term clinical data.
Summary not available.
REGENXBIO (Nasdaq: RGNX) said the FDA placed a clinical hold on investigational gene therapies RGX-111 (MPS I) and RGX-121 (MPS II) after a single case of an intraventricular CNS tumor was found in a participant treated with RGX-111.
Preliminary analysis detected an AAV vector genome integration event linked to PLAG1 overexpression; causality is undetermined and the investigation is ongoing. The affected participant is asymptomatic with developmental gains. No neoplasm reported in nine other RGX-111 patients or 32 RGX-121 patients. REGENXBIO awaits the full FDA hold letter.
