SNDX shareholders saw the market open to losses of more than 11% after the Phase 2 MAXPIRe trial of axatilimab missed its primary endpoint in idiopathic pulmonary fibrosis. SueWallSt notifies investors of a pending investigation into potential securities law violations on behalf of investors who lost money.

NEW YORK, Oct. 13, 2026 /PRNewswire/ -- On the morning of October 13, 2026, Syndax Pharmaceuticals (NASDAQ: SNDX) shares opened at about $14.61 per share, down 11.72% from the October 12 close after the Company announced that axatilimab failed to meet the primary endpoint of its Phase 2 MAXPIRe trial in idiopathic pulmonary fibrosis (IPF). If you bought SNDX and are now holding a loss, or sold into the decline, you may be able to seek recovery. Submit your SNDX loss details now for a free evaluation, or contact Joseph E. Levi, Esq. via email at [email protected] or by telephone at (888) SueWallSt.

The 145-patient MAXPIRe trial measured the annualized rate of decline in forced vital capacity (FVC), a measure of lung function. The trial showed no benefit for axatilimab on that endpoint. Syndax said it would not pursue further development of axatilimab in IPF, and its graft-versus-host disease programs continue. Previously, during Syndax's fourth quarter fiscal 2025 earnings call on February 26, 2026, Chief Medical Officer Botwood described the study as having the "potential to provide robust proof-of-concept data for axatilimab in IPF" and later indicated they were "feeling really quite confident in both the design and the outcome" of the trial.

SueWallSt notifies investors of a pending investigation on behalf of SNDX shareholders who suffered losses. Any SNDX investor who lost money in the October 13 selloff is encouraged to request a free review of their losses. Joseph E. Levi, Esq. can also be reached by email at [email protected] or by telephone at (888) SueWallSt.

By midday the stock had faltered by more than $2.50, or 15%, from the previous day's closing price.

Investors who purchased shares at allegedly inflated prices and suffered losses may be eligible to seek compensation.

Q: Who is eligible to participate in the SNDX investigation?A: Investors who purchased SNDX stock or securities and suffered financial losses may be eligible. Eligibility is based on purchase date and documented losses -- not on whether you still hold the shares.

Submit your information for a no-cost, no-obligation evaluation of your potential recovery. No immediate action is required to remain eligible to participate in the investigation.
