Contingencies Disclosure [Text Block] | 12. Contingencies The Company is, and from time to time, the Company may become, involved in litigation or other legal proceedings and claims, including U.S. government inquiries, investigations and Citizen Petitions submitted to FDA. In addition, the Company has received, and from time to time may receive, inquiries from government authorities relating to matters arising from the ordinary course of business. The outcome of these proceedings is inherently uncertain. Regardless of outcome, legal proceedings can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors. At this time, no assessment can be made as to their likely outcome or whether the outcome will be material to the Company other than as disclosed below. The Company believes that its total provisions for legal matters are adequate based upon currently available information. Update on Government Investigations Beginning in August 2021, the Company has received subpoenas, a Civil Investigative Demand (“CID”) and other requests for documents and information from the Department of Justice (“DOJ”) and document requests from the SEC, each seeking corporate information and documents concerning the research and development of simufilam and/or SavaDx. The Company has been providing documents and information in response to these subpoenas, the CID and requests for information. On September 26, 2024, the Company announced that it had reached a settlement with the SEC resolving the SEC investigation of the Company’s disclosures regarding its Phase 2b clinical trial of simufilam for the treatment of Alzheimer’s disease (the “Phase 2b Study”) and related matters. The SEC also agreed to a settlement with two former senior employees of the Company. Pursuant to these settlements, the U.S. District Court for the Western District of Texas entered final consent judgment on October 18, 2024, on a complaint filed by the SEC against the Company and its two former senior employees. The Company has neither admitted nor denied the allegations of the complaint. The SEC’s complaint alleged that certain disclosures by the Company regarding the Phase 2b Study violated certain federal securities laws and SEC rules, including negligence-based disclosure violations of Sections 17(a)(2) and 17(a)(3) of the Securities Act of 1933, as amended (the “Securities Act”), as well as recordkeeping and reporting requirements under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The complaint alleges that the Company’s SEC reports and other public statements regarding the Phase 2b Study negligently contained materially misleading statements and omissions. The SEC’s allegations with respect to the Company’s two former employees relate to these employees’ roles in such disclosures. Under its settlement, the Company consented to a permanent injunction against future violations of Section 17(a) of the Securities Act, Section 13(a)(1) of the Exchange Act and Rules 12b-20, 13a-1, 13a-11 and 13a-13 under the Exchange Act. In addition, the Company paid a civil monetary penalty of $40 million in November 2024. The Company continues to cooperate with the DOJ related to requests for documents and information, including those related to conduct alleged in the indictment of Dr. Hoau-Yan Wang announced by DOJ on June 28, 2024. The Company cannot predict the outcome or impact of ongoing matters, including whether a government authority may pursue an enforcement action against the Company or others. The Company does not at this time anticipate, however, that DOJ will bring criminal charges against or seek a criminal resolution with the Company. Securities Class Actions and Shareholder Derivative Actions Between August 27, 2021 and October 26, 2021, four putative class action lawsuits were filed alleging violations of the federal securities laws by the Company and certain named officers. The complaints rely on allegations contained in Citizen Petitions submitted to FDA and allege that various statements made by the defendants regarding simufilam were rendered materially false and misleading. The Citizen Petitions were all subsequently denied by FDA. These actions were filed in the U.S. District Court for the Western District of Texas. The complaints seek unspecified compensatory damages and other relief on behalf of a purported class of purchasers. On June 30, 2022, a federal judge consolidated the four class action lawsuits into one case and appointed a lead plaintiff and a lead counsel. Lead plaintiff filed a consolidated amended complaint on August 18, 2022 on behalf of a putative class of purchasers of the Company’s securities between September 14, 2020 and July 26, 2022. On May 11, 2023, the court dismissed with prejudice plaintiffs’ claims against defendant Nadav Friedmann, PhD, MD, our former Chief Medical Officer and a Company director, who is now deceased, but otherwise denied defendants’ motion to dismiss. Defendants filed an answer to the consolidated amended complaint on July 3, 2023. On February 22, 2024, plaintiffs filed a motion to supplement their complaint to extend the putative class period through October 12, 2023. The court granted that Motion on June 12, 2024, and plaintiffs filed a supplemental complaint on June 13, 2024. On November 13, 2024, Plaintiffs filed a second motion to supplement their complaint. On March 13, 2024, plaintiffs filed a Motion for Class Certification. On February 25, 2025, the Court denied Plaintiff’s Motion for Class Certification without prejudice, explaining that rulings on pending motions, including specifically Plaintiffs’ second motion to supplement their complaint, could affect disposition of class certification. On November 4, 2021, a related shareholder derivative action was filed, purportedly on behalf of the Company, in the U.S. District Court for the Western District of Texas, asserting claims under the U.S. securities laws and state fiduciary duty laws against certain named officers and the members of the Company’s Board. This complaint relies on the allegations made in Citizen Petitions that were submitted to (and subsequently denied by) FDA. The complaint alleges, among other things, that the individual defendants exposed the Company to unspecified damages and securities law liability by causing it to make materially false and misleading statements, in violation of the U.S. securities laws and in breach of their fiduciary duties to the Company. The derivative case seeks, among other things, to recover unspecified compensatory damages on behalf of the Company arising out of the individual defendants’ alleged wrongful conduct. Although the plaintiff in this derivative case does not seek relief against the Company, the Company has certain indemnification obligations to the individual defendants. Between November 4, 2021 and June 20, 2023, four additional shareholder derivative actions were filed alleging substantially similar claims, two in the U.S. District Court for the Western District of Texas, one in Texas state court (Travis County District Court) and one in the Delaware Court of Chancery. On July 5, 2022, the three actions in the Western District of Texas were consolidated into a single action. All of the foregoing actions are currently stayed pending further developments in the consolidated securities action described above. On November 9, 2023, another shareholder derivative action alleging substantially similar claims was filed in the U.S. District Court for the Western District of Texas. The parties to that case expect that it will be consolidated into the existing consolidated federal court shareholder derivative action. On February 2, 2024, a putative class action lawsuit was filed, purportedly on behalf of the Company, alleging violations of the federal securities law by the Company and certain named officers. The complaint relies on an October 12, 2023 article that describes a purported leaked report of alleged scientific misconduct by a scientific collaborator of the Company at City University of New York. The complaint alleges that various statements made by the defendants regarding simufilam were rendered materially false and misleading by this article. The action was filed in the U.S. District Court for the Northern District of Illinois. The complaint seeks unspecified compensatory damages and other relief on behalf of a purported class of purchasers of the Company’s securities between August 18, 2022 and October 12, 2023. On May 28, 2024, the Northern District of Illinois transferred this action to the Western District of Texas. Beginning on March 18, 2024, two related shareholder derivative actions were filed, purportedly on behalf of the Company, in the U.S. District Court for the Northern District of Illinois, asserting claims under the U.S. securities laws and state fiduciary duty laws against certain named officers and the members of the Company’s Board. The complaints rely on an October 12, 2023 article that describes a purported leaked report of alleged scientific misconduct by a scientific collaborator of the Company at City University of New York. The complaints allege, among other things, that the individual defendants exposed the Company to unspecified damages and securities law liability by causing it to make materially false and misleading statements, in violation of the U.S. securities laws and in breach of their fiduciary duties to the Company. The derivative cases seek, among other things, to recover unspecified compensatory damages on behalf of the Company arising out of the individual defendant’s alleged wrongful conduct. Although the plaintiffs in these derivative cases do not seek relief against the Company, the Company has certain indemnification obligations to the individual defendants. On September 6, 2024, these two cases were consolidated and stayed pending further developments in the shareholder class action initially filed in the Northern District of Illinois on February 2, 2024. The Company disputes the allegations and intends to defend against these lawsuits vigorously. The Company is unable to estimate the possible loss or range of loss, if any, associated with these lawsuits. On December 13, 2024, a putative class action lawsuit was filed, purportedly on behalf of the Company, alleging violations of the federal securities law by the Company and certain named officers. The complaint alleges that various statements made by the defendants regarding simufilam were revealed to be materially false and misleading by the release of top-line results for the Company’s RETHINK-ALZ Phase 3 clinical trial on November 25, 2024. The action was filed in the U.S. District Court for the Western District of Texas. The complaint seeks unspecified compensatory damages and other relief on behalf of a purported class of purchasers of the Company’s securities between February 7, 2024, and November 24, 2024. The Company believes that the likelihood of an unfavorable outcome is not probable, however, it is reasonably possible that the Company may incur a loss. The Company is unable to reasonably estimate the amount or range of potential loss at this time. On August 19, 2022, a shareholder derivative action was filed, purportedly on behalf of the Company, in the Delaware Court of Chancery, asserting claims under state fiduciary duty laws against certain named officers and members of the Company’s Board. The complaint alleges, among other things, that the individual defendants breached their fiduciary duties by approving the CIB Plan in August 2020. The complaints sought unspecified compensatory damages and other relief. On January 6, 2023, the plaintiffs filed an amended complaint. Defendants filed a partial answer to the amended complaint on March 10, 2023, and moved to partially dismiss the amended complaint on March 14, 2023. On May 28, 2024, the parties entered into a Stipulation and Agreement of Settlement, Compromise, and Release (the “Stipulation”) to resolve the action. The Stipulation and exhibits thereto, including the proposed Notice of Pendency of Settlement of Class and Derivative Action (the “Notice”) and [Proposed] Scheduling Order with Respect to Notice and Settlement Hearing (the “Scheduling Order”), were filed in the Delaware Court of Chancery on May 28, 2024. On June 26, 2024, the Delaware Court of Chancery entered the Scheduling Order, which included approval of the Notice. The Delaware Court of Chancery held a settlement hearing on September 9, 2024. On January 24, 2025, the Delaware Court of Chancery entered a Final Order and Judgment approving the Stipulation and dismissing the action with prejudice. Pursuant to the Final Order, the Company paid $1 million in attorneys’ fees and expenses in February 2025, which was recorded in accounts payable and other accrued expenses at December 31, 2024. Anti-SLAPP Lawsuit On August 6, 2024, a lawsuit was filed in the District Court for the Southern District of New York which, as amended and as joined by intervenor plaintiffs, asserts claims, including a claim under the New York Anti-SLAPP Law, against the Company and against two former officers to whom the Company has certain indemnification obligations. The amended complaint and the complaint in intervention seeks costs and damages relating to a defamation action filed by the Company against the plaintiffs and subsequently dismissed voluntarily and without prejudice by the Company. The Company intends to defend the lawsuit vigorously. The Company is unable to estimate the possible loss or range of loss, if any, associated with this lawsuit.
