Rocket Pharmaceuticals Faces Lawsuit Over Gene Therapy Protocol Changes

Rocket Pharmaceuticals Faces Class Action Lawsuit
Rocket Pharmaceuticals, Inc. (NASDAQ: RCKT) recently found itself at the center of a legal storm when it announced that the FDA had placed a clinical hold on its critical Phase 2 trial for RP-A501. This therapy is intended for patients with Danon disease, a rare genetic disorder. Following this announcement, investors witnessed a staggering decline in share value, with losses exceeding 60% in a single trading session.
The Background of the Litigation
Danon disease is recognized for causing multiple organ dysfunctions and is often associated with severe cardiac issues that can lead to premature death. The implications of this condition highlight the urgency behind Rocket Pharmaceuticals’ efforts and the stakes for its investors.
As a response to these troubling developments, a class action lawsuit titled Ho v. Rocket Pharmaceuticals, Inc. was initiated. The suit is seeking to represent those investors who purchased shares of Rocket Pharmaceuticals from February 27, 2025, through May 26, 2025, who may have suffered financial losses as a result of the recent events.
Investor Advocacy
Hagens Berman, the law firm leading the case, has encouraged investors impacted by these events to join the lawsuit. The firm also welcomes individuals who possess pertinent information about the case to reach out, potentially assisting in their investigation.
Timing of Events
According to the lawsuit, the class period runs from February 27 to May 26, 2025, focusing on statements made by Rocket Pharmaceuticals regarding its RP-A501 clinical trial. Investors were reassured by the company’s communications about the trial’s progress and potential efficacy without full disclosure of the risks associated with the treatment.
Investors were reportedly unaware that the study protocol had been modified to include a new agent, which was not communicated to them in a timely manner. Such modifications, especially involving a therapy aimed at a vulnerable population, raise significant ethical and legal questions.
The Impact of the Clinical Hold
The fallout from the FDA’s clinical hold was severe. On May 27, during a communications update with analysts, Rocket Pharmaceuticals revealed that the hold was enacted following a patient’s serious adverse event that culminated in death. This revelation contradicted previous company assurances and led to a dramatic drop in stock prices, highlighting the disconnect between corporate statements and investor realities.
From a closing price of $9.40 on February 27, the stock price plummeted by over 62% in one day, and down approximately 75% compared to its earlier share value recorded before the announcement.
Legal Implications and Investor Rights
The class action lawsuit argues that Rocket's previous statements resulted in an artificially inflated stock price. The failure to disclose changes in the clinical trial protocol and the potential risks had monumental repercussions for investors, many of whom faced substantial financial losses.
Lead attorney Reed Kathrein from Hagens Berman stated that the firm is looking into claims suggesting that Rocket Pharmaceuticals misled its investors regarding the safety and efficacy of the RP-A501 trial protocol.
What Investors Need to Know
If you are an investor in Rocket Pharmaceuticals and experienced financial setbacks from these developments, it is recommended to document your losses and consider joining the class action. The deadline to apply for lead plaintiff status is August 11, 2025.
