NEW YORK, Feb. 23, 2026 (GLOBE NEWSWIRE) -- Axsome Therapeutics, Inc. (NASDAQ: AXSM), a biopharmaceutical company leading a new era in the treatment of central nervous system (CNS) disorders, today announced financial results for the fourth quarter and full year 2025 and provided a general business update.

“Our fourth quarter and full year 2025 results demonstrate strong commercial momentum across our marketed products, and advancement and expansion of our innovative CNS pipeline, which now includes five differentiated product candidates,” said Herriot Tabuteau, MD, Chief Executive Officer of Axsome Therapeutics. “2026 promises to be another eventful year for Axsome with continued commercial execution, and multiple regulatory and clinical milestones including potential FDA action on our sNDA for AXS-05 in Alzheimer’s disease agitation, NDA filing for AXS-12 in narcolepsy, and clinical trial progress across our development portfolio.”

Fourth Quarter and Full Year 2025 Financial Highlights

Total net product revenue was $196.0 million for the fourth quarter 2025 and $638.5 million for the full year 2025, representing 65% and 66% year-over-year growth. Total net product revenue for the comparable periods in 2024 were $118.8 million and $385.7 million, respectively. The increase was driven by strong growth of AUVELITY and SUNOSI, and contributions from the recent launch of SYMBRAVO.

AUVELITY net product sales were $155.1 million for the fourth quarter 2025 and $507.1 million for the full year 2025, representing 68% and 74% year-over-year growth, in the third full year of commercial launch. AUVELITY net product sales for the comparable periods in 2024 were $92.6 million and $291.4 million, respectively.

SUNOSI net product revenue was $36.7 million for the fourth quarter 2025 and $124.8 million for the full year 2025, representing 40% and 32% year-over-year growth. SUNOSI revenue for the fourth quarter consisted of $35.4 million in net product sales and $1.3 million in royalty revenue from sales in out-licensed territories. SUNOSI revenue for the year consisted of $120.1 million in net product sales and $4.7 million in royalty revenue from sales in out-licensed territories. SUNOSI net product revenues for the comparable periods in 2024 were $26.2 million and $94.3 million, respectively, which consisted of $24.7 million and $90.3 million in net product sales.

SYMBRAVO net product sales were $4.1 million for the fourth quarter 2025 and $6.6 million for the full year 2025.

Total cost of revenue was $12.3 million for the fourth quarter 2025 and $47.5 million for the full year 2025, compared to $10.5 million and $33.3 million for the fourth quarter and full year 2024.

Research and development (R&D) expenses were $48.8 million for the fourth quarter 2025 and $183.3 million for the full year 2025, compared to $55.0 million and $187.1 million for the fourth quarter and full year 2024. The decrease for the year primarily reflects the completion of clinical trials for AXS-05 in Alzheimer’s disease agitation and for solriamfetol in ADHD and MDD, partially offset by one-time acquisition-related expenses and higher costs related to AXS-07.

Selling, general, and administrative (SG&A) expenses were $169.3 million for the fourth quarter 2025 and $570.6 million for the full year 2025, compared to $113.3 million and $411.4 million for the fourth quarter and full year 2024. The increase for the year primarily reflects commercialization activities for AUVELITY, including the sales force expansion and the national launch of our direct-to-consumer advertising campaign, and the commercial launch of SYMBRAVO.

Net loss was $28.6 million, or $(0.56) per share, for the fourth quarter 2025 and $183.2 million, or $(3.68) per share, for the full year 2025, compared to a net loss of $74.9 million, or $(1.54) per share, for the fourth quarter 2024 and $287.2 million, or $(5.99) per share, for the full year 2024. Net loss for the fourth quarter 2025 includes $22.7 million in stock-based compensation expense compared to $22.0 million in stock-based compensation expense for the fourth quarter 2024. Net loss for the full year 2025 includes $93.8 million in stock-based compensation expense, compared to $85.2 million in stock-based compensation expense for the full year 2024.

Cash and cash equivalents totaled $322.9 million at December 31, 2025, compared to $315.4 million at December 31, 2024.

Shares of common stock outstanding were 50,882,766 at December 31, 2025.

Development Pipeline

Axsome is advancing an industry-leading neuroscience pipeline of multiple, innovative, patent-protected product candidates addressing serious psychiatric and neurological conditions. Recent and anticipated progress for key pipeline programs is summarized below.

AXS-05

AXS-05 (dextromethorphan-bupropion) is Axsome’s novel, oral, investigational N-methyl-D-aspartate (NMDA) receptor antagonist, sigma-1 agonist, and aminoketone CYP2D6 inhibitor being developed for the treatment of Alzheimer’s disease (AD) agitation and smoking cessation.

Alzheimer’s Disease Agitation: Axsome’s sNDA for AXS-05 for the treatment of Alzheimer’s disease agitation was accepted for filing and granted Priority Review designation by the U.S. Food and Drug Administration (FDA) with a Prescription Drug User Fee Act (PDUFA) target action date of April 30, 2026. AXS-05 was previously granted FDA Breakthrough Therapy designation for AD agitation.

Smoking Cessation: Axsome plans to initiate a pivotal Phase 2/3 trial of AXS-05 in smoking cessation in the second quarter of 2026.

Solriamfetol

Solriamfetol is Axsome’s dopamine and norepinephrine reuptake inhibitor (DNRI), TAAR1 agonist, and 5-HT_1A agonist being developed for the treatment of attention deficit hyperactivity disorder (ADHD), major depressive disorder (MDD) with excessive daytime sleepiness (EDS) symptoms, binge eating disorder (BED), and excessive sleepiness associated with shift work disorder (SWD).

Attention Deficit Hyperactivity Disorder: Axsome plans to conduct two pediatric Phase 3 trials of solriamfetol, one in children and one in adolescents, following a recent Type B meeting with the FDA. The Company plans to initiate both trials in the first half of 2026.

Major Depressive Disorder with Excessive Daytime Sleepiness symptoms: Axsome is on track to initiate a Phase 3 trial of solriamfetol in MDD patients with EDS symptoms in the first quarter of 2026.

Binge Eating Disorder: Axsome is conducting the ENGAGE study, a Phase 3, randomized, double-blind, placebo-controlled, multicenter trial evaluating the efficacy and safety of solriamfetol in BED. The Company anticipates topline results from the ENGAGE Phase 3 trial in the second half of 2026.

Shift Work Disorder: Axsome is conducting the SUSTAIN study, a Phase 3, randomized, double-blind, placebo-controlled, multicenter trial evaluating the efficacy and safety of solriamfetol in SWD in adults. Based on current enrollment trends, the Company anticipates topline results from the SUSTAIN Phase 3 trial in 2027.

AXS-12

AXS-12 (reboxetine) is Axsome’s novel, oral, investigational, highly selective and potent norepinephrine reuptake inhibitor and cortical dopamine modulator being developed for the treatment of narcolepsy.

Narcolepsy: In December 2025, Axsome received formal pre-NDA meeting minutes from the FDA supporting an NDA submission for AXS-12 in narcolepsy. The Company is on track to submit the NDA this quarter. AXS-12 has been granted FDA Orphan Drug designation for narcolepsy.

AXS-14 (esreboxetine) is Axsome’s novel, oral, investigational, highly selective and potent norepinephrine reuptake inhibitor being developed for the management of fibromyalgia. Esreboxetine is the SS-enantiomer of reboxetine.

Fibromyalgia: In January 2026, Axsome initiated the FORWARD study, a Phase 3, double-blind, placebo-controlled, randomized withdrawal trial evaluating the efficacy and safety of AXS-14 for the management of fibromyalgia. This trial will complement the previously completed parallel-group Phase 2 and Phase 3 trials, both of which met their primary endpoints.

AXS-17

AXS-17 is Axsome’s novel oral GABA_A receptor α2,3 subtype-selective positive allosteric modulator (PAM) being developed for the treatment of epilepsy.

Epilepsy: In November 2025, Axsome acquired AZD7325, now designated AXS-17. The Company has initiated tech transfer activities and Phase 2 trial-enabling activities.

Corporate Updates

In February 2026, Axsome announced that it resolved patent litigation with Alkem Laboratories Ltd. related to Alkem’s Abbreviated New Drug Application (ANDA) for a generic version of SUNOSI. The Company entered into a license and settlement agreement with Alkem, which permits Alkem to begin selling its generic version of SUNOSI on or after September 1, 2040, if pediatric exclusivity is granted, or on or after March 1, 2040, if no pediatric exclusivity is granted, subject to FDA approval and conditions and exceptions customary for agreements of this type.
