Del. Ch.Jul 9, 2026Background
- Axsome Therapeutics disclosed regulatory setbacks for its AXS-07 migraine drug by April 25, 2022, and its stock dropped after the FDA reported unresolved CMC issues. 1
- Plaintiffs claim Axsome and its officers made materially false or misleading statements from 2019 to April 2022 about AXS-07’s NDA prospects and CMC status. 2
- A stockholder filed a federal securities class action in 2022, and two stockholders later filed a consolidated federal derivative action that remained stayed during the securities case. 3
- Wickstrom sent a books-and-records demand on April 24, 2025, Gildea served one on May 2, 2025, and Axsome produced documents in September 2025. 4
- Wickstrom filed this Delaware derivative action on September 23, 2025, Gildea filed six days later, and defendants moved to dismiss. 5
- The court held the claims accrued by April 22, 2022, were filed after the three-year limitations period, and were time-barred by laches. 6
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| When did the fiduciary-duty claims accrue? 7 | Claims accrued only when plaintiffs learned the truth through later demand responses. | Claims accrued when the challenged statements were made. | Claims accrued by April 22, 2022, when the statements were disseminated. 8 |
| Did inquiry notice toll limitations? 9 | The limitations period was tolled until suit because the fraud was not fully revealed sooner. | Inquiry notice arose by April 25, 2022, ending any tolling. | Tolling ended by April 25, 2022; the suit was still untimely. 10 |
| Did the Section 220 demands equitably toll limitations? 11 | Serving books-and-records demands suspended limitations until filing suit. | Only a diligent Section 220 action can toll; out-of-court demands do not. | No tolling; the demands were untimely or improperly served and not diligently pursued. 12 |
| Were defendants prejudiced by the late filing? 13 | Parallel federal derivative litigation eliminated any prejudice. | Late filing presumes prejudice, compounded by parallel litigation. | Prejudice is presumed and unrebutted; laches bars the claims. 14 |
