Axsome obtains exclusive global rights to balipodect, a potentially first-in-class selective phosphodiesterase 10A inhibitor

Acquisition further expands Axsome’s industry-leading CNS portfolio with a novel mechanism for neuropsychiatric conditions

NEW YORK, April 01, 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 that it has entered into an asset purchase agreement to obtain exclusive global rights to TAK-063 (balipodect), a novel, oral, potent, and selective phosphodiesterase 10A (PDE10A) inhibitor from Takeda. Axsome intends to develop the selective inhibitor for the treatment of schizophrenia and Tourette syndrome, and plans to begin Phase 3 trial-enabling activities for the schizophrenia indication in 2026.

“We are pleased to add balipodect, a selective PDE10A inhibitor, to our industry-leading neuroscience pipeline. We believe that its new and potentially first-in-class mechanism of action is relevant to multiple neuropsychiatric conditions, and we are well positioned to advance its development initially in schizophrenia and Tourette syndrome,” said Herriot Tabuteau, MD, Chief Executive Officer of Axsome. “This novel molecule complements and enhances our innovative pipeline as we continue to develop and deliver differentiated treatment options to improve the brain health of millions of individuals.”

Balipodect has completed a 164-patient proof-of-concept Phase 2 trial in schizophrenia. The selective PDE10A inhibitor has demonstrated a favorable safety and tolerability profile in clinical studies in over 360 individuals to date.

Under the terms of the agreement, Axsome obtained worldwide commercial, development, and manufacturing rights to balipodect. Takeda received an upfront payment and is eligible to receive additional payments related to development, regulatory, and commercial milestones for the first two indications, as well as royalties related to potential global net sales.

About Schizophrenia

Schizophrenia is a debilitating chronic neuropsychiatric condition characterized by three main symptom domains, including positive (e.g., hallucinations, delusions, disorganized thinking and speech), negative (e.g., loss of motivation, social withdrawal, diminished emotional expression, decreased ability to feel pleasure), and cognitive (e.g., impaired attention and concentration, memory deficits).^1,2 It is part of a broader spectrum of related psychotic disorders that impact approximately 3.7 million people in the United States, and is one of the leading causes of disability worldwide.^3,4 Schizophrenia is associated with significantly impaired daily functioning, markedly reduced life expectancy, and substantial social and economic burden.^5,6

About Balipodect

Balipodect is a potent selective inhibitor of phosphodiesterase 10A (PDE10A), an enzyme selectively expressed in medium spiny neurons of the striatum.⁷ Inhibition of PDE10A is a new mechanism of action and potential therapeutic target for several neuropsychiatric conditions including schizophrenia and Tourette syndrome. The selective inhibitor regulates levels of cAMP and cGMP downstream of dopamine D₁ and D₂ receptor signaling in the medium spiny neurons of the striatum. In preclinical and clinical studies to date, balipodect did not increase glucose or prolactin levels, and this lack of metabolic effects may be due in part to the selective, striatal expression of PDE10A and the activity of balipodect downstream of the dopamine receptor in D₁- and D₂-receptor-expressing neurons.^7-10
