ACAD

Acadia Pharmaceuticals generated $576 million in first-half 2026 revenues, up 13% year-over-year, and raised its full-year 2026 guidance to $1.24-$1.30 billion. Nuplazid sales grew 7% to $350.1 million with patent protection until February 2038, while Daybue sales jumped 25% to $226 million, driven by the new STIX formulation and EU approval for Rett syndrome treatment. However, ACAD shares have underperformed the industry by 27.3% year-to-date and face increasing competition from rivals like Axsome and Neurogene.

Four central nervous system (CNS) pharmaceutical companies—Axsome Therapeutics, Neurocrine Biosciences, Alkermes, and Acadia Pharmaceuticals—are highlighted as relevant investment opportunities ahead of World Mental Health Day. All four companies carry a Zacks Rank #3 (Hold) rating and have strong CNS portfolios with meaningful revenue growth in H1 2026, supported by expanding pipelines addressing psychiatric and neurological disorders.

Acadia Pharmaceuticals received a Notice of Allowance from the USPTO that extends patent protection for trofinetide (Daybue) to March 2041, adding nearly five years to existing coverage. Daybue sales grew 25% to $226 million in H1 2026, and the drug received EU approval in August 2026, becoming the first and only approved treatment for Rett syndrome in Europe.

Over 200 companies are advancing more than 240 pipeline Alzheimer's disease therapies across various clinical development stages. The market is being driven by an aging population, rising disease prevalence, and the emergence of disease-modifying therapies that enable earlier intervention and biomarker-guided care. Two therapies have recently received FDA approval: KISUNLA (donanemab) from Eli Lilly and LEQEMBI (lecanemab-irmb) from Eisai/Biogen, both targeting amyloid plaques to slow disease progression.

Axsome Therapeutics (AXSM) reported strong first-half 2026 results with its lead drug Auvelity generating $333 million in sales, up 54.2% year-over-year. The company is expanding Auvelity's market reach through FDA approval for Alzheimer's agitation treatment and a phase III smoking cessation study. Additional revenue support comes from Sunosi ($66.5M sales) and newly launched Symbravo ($6.3M sales), though the company faces intense competition in the CNS and migraine markets.
