What Is This Lawsuit About? The lawsuit alleges that the Company represented that the key clinical trials supporting the use of relacorilant as treatment for patients with hypercortisolism were “powerful support” for the New Drug Application (“NDA”) that Corcept submitted to the U.S. Food and Drug Administration (“FDA”) for this indication. The Company also stated that they had communicated with the FDA about this NDA and were confident in submitting the NDA, foreseeing no impediments to approval. Toward the latter part of the Class Period, Corcept repeatedly told investors that “relacorilant is approaching approval.” In truth, the FDA had repeatedly raised concerns about the adequacy of the clinical evidence supporting the relacorilant NDA and, as a result, there was a known material risk that Corcept’s relacorilant NDA would not be approved.

On December 31, 2025, when Corcept revealed that the FDA had issued a Complete Response Letter (“CRL”) regarding the NDA for relacorilant as a treatment for patients with hypercortisolism. The press release issued by the Company stated that the FDA had “concluded it could not arrive at a favorable benefit-risk assessment for relacorilant without Corcept providing additional evidence of effectiveness.” As a result of this disclosure, the price of Corcept common stock declined by $35.40 per share, or 50.4%. On this news, the price of Corcept shares declined by $35.40 per share, or approximately 50.4%, from $70.20 per share on December 30, 2025 to close at $34.80 on December 31, 2025.

On January 30, 2026, after the end of the Class Period, the FDA published a redacted copy of the CRL. The CRL detailed the FDA’s concerns with the relacorilant NDA, including concerns that the clinical studies that were submitted as part of the NDA were not sufficient evidence of relacorilant’s efficacy for the proposed indication. The CRL also noted that, during pre-submission meetings, the FDA informed Corcept “on several occasions” of its “concerns about the adequacy of the clinical development program,” and had warned the Company “to expect significant review issues,” if it submitted the application. On this news, the price of Corcept shares declined by $4.74 per share, or approximately 10.6%, from $44.61 per share on January 29, 2026 to close at $39.87 on January 30, 2026.

The Lead Plaintiff Appointment Process. The federal securities laws permit any investor who acquired eligible securities during the class period to seek appointment as lead plaintiff in a class action lawsuit. Courts typically appoint the investor(s) with the largest financial loss in the case and the ability to represent the class rather than investors with simply the largest investment portfolio. Courts regularly appoint individual investors, whether acting alone or as a group, as lead plaintiffs. The rights of any investor who bought shares during the class period are generally already protected. However, lead plaintiffs have the power to influence case strategy and have a say in settlement decisions, as well as decisions concerning allocation of settlement funds among class members.
