Investigation into Regenxbio Inc.: Disclosure Concerns Amid FDA Action

Introduction

The recent turmoil surrounding Regenxbio Inc. (NASDAQ: RGNX) has come under scrutiny as law firm Levi & Korsinsky, LLP seeks to determine whether the biotech company adequately communicated crucial information to investors related to its gene therapy clinical programs. Following the FDA's decision to place clinical holds on Regenxbio's RGX-111 and RGX-121 programs, concerns have emerged regarding the completeness and transparency of disclosures made to shareholders.

Background on the Issue

On January 28, 2026, Regenxbio filed a Form 8-K statement announcing that the FDA had halted testing for its clinical programs after a tumor was discovered in a participant. This disclosure triggered a dramatic fall in stock prices, estimated to be between 30% to 35%. The situation raises significant questions about the information provided to investors, particularly related to the risks inherent in the ongoing clinical trials.

Legal Compliance and Obligations

Publicly traded companies, as mandated by SEC disclosure rules, must provide material information to investors that is essential for making informed investment decisions. The guidelines allow companies to report critical events that may not be covered by existing reporting requirements through Form 8-K. Additionally, Rule 10b-5 under the Securities Exchange Act of 1934 prohibits any misrepresentation or omission of facts that could mislead investors.

During Regenxbio's Q3 2025 earnings call on November 6, 2025, CEO Curran Simpson expressed optimism regarding favorable inspections from the FDA, stating that the agency completed assessments of their clinical sites without reservations, labeling it a significant milestone. However, the absence of any mention regarding the RGX-111 program or safety concerns indicated a potential oversight in providing a balanced view of the company’s regulatory standing.

Disclosure Gaps

The court of public opinion is questioning the completeness of disclosures, especially since the Q3 earnings call did not address key developments related to the RGX-111 gene therapy program for MPS I. This omission raises alarms about the firm’s communication strategy and the potential impact it could have had on investors who could have failed to analyze the associated risks thoroughly.

Investors are now left pondering whether they had been adequately informed of the risks involved when they purchased shares in Regenxbio. The lack of comprehensive disclosures creates a perception of an asymmetric representation of the company's overall health and regulatory compliance, leading to investor mistrust and legal scrutiny.

Next Steps for Affected Investors

For shareholders who may have incurred losses due to the decline in stock value following the FDA’s announcement, Levi & Korsinsky has invited interested parties to come forward to discuss their legal rights. The firm emphasizes that consultations are without cost or obligation, highlighting their extensive experience and proven track record in securities litigation.

Conclusion

The situation surrounding Regenxbio, marked by its rapid stock decline and questions regarding the adequacy of disclosures, serves as a crucial reminder of the importance of transparency in the biotech sector. As the investigation continues, the outcome will not only affect the company’s future but also serve as a gauge of regulatory and corporate accountability. Stakeholders should remain vigilant as this situation unfolds, ensuring that compliance and disclosure obligations are met moving forward.
