  A putative securities class action complaint was filed in February 2026, alleging the company misled investors regarding the viability and safety of its RGX-111 study, following the FDA's regulatory actions.

The 10-K filing reveals REGENXBIO's auditors have raised "substantial doubt" about the company's ability to continue as a going concern, citing cumulative losses and cash outflows. This critical financial warning is compounded by significant setbacks in its gene therapy pipeline. The FDA issued clinical holds on both RGX-121 (MPS II) and RGX-111 (MPS I) programs in January 2026, followed by a Complete Response Letter (CRL) for the RGX-121 BLA in February 2026, questioning the study design and efficacy evidence. These regulatory hurdles directly impact the company's ability to commercialize these therapies and have led to a putative securities class action lawsuit. Additionally, a key supplier for its retinal program, Clearside Biomedical, filed for bankruptcy, introducing supply chain risks. While the company reported increased revenue from collaborations and pipeline progress in other areas, these severe challenges create a highly uncertain outlook for investors.
