Neurocrine Biosciences Announces U.S. FDA Approval of INGREZZA® SPRINKLE (valbenazine) Capsules


SAN DIEGO, April 30, 2024 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced the U.S. Food and Drug Administration has approved INGREZZA® SPRINKLE (valbenazine) capsules, a new oral granules formulation of INGREZZA® (valbenazine) capsules prescribed for the treatment of adults with tardive dyskinesia and chorea associated with Huntington's disease.1 INGREZZA SPRINKLE provides an alternative administration option for those who experience dysphagia or have difficulty swallowing.

Like the original formulation of INGREZZA capsules, INGREZZA SPRINKLE offers simple dosing that's always one capsule, once daily with no complex titration.1 INGREZZA is the only selective vesicular monoamine transporter 2 (VMAT2) inhibitor that offers three effective dosages (40 mg, 60 mg and 80 mg) that can be adjusted by the healthcare provider based on patient response and tolerability.1 INGREZZA SPRINKLE offers the same dosage strengths, and the contents of the capsules can be easily sprinkled on soft food for oral administration.

"We developed INGREZZA SPRINKLE to make administration easier for patients who have difficulty swallowing or prefer not to take a capsule," said Eiry W. Roberts, M.D., Chief Medical Officer at Neurocrine Biosciences. "We are pleased to offer the proven efficacy of INGREZZA in reducing uncontrollable movements in a new formulation."

Taking pills can be difficult for people experiencing chorea associated with Huntington's disease (HD) in addition to those living with tardive dyskinesia (TD)2:

  •  In a survey of patients with chorea associated with HD and their caregivers (n = 78), 62% reported difficulty swallowing because of their involuntary movements. ‡,†
  •  In a survey of patients with TD experiencing moderate-to-severe involuntary movement symptoms (n = 250), 37% reported that their movements impacted their ability to eat and drink.*,§

The U.S. Food and Drug Administration (FDA) approval was based on chemistry, manufacturing, and controls information and data demonstrating the bioequivalence and tolerability of INGREZZA SPRINKLE compared to INGREZZA capsules.

About Tardive Dyskinesia (TD)Tardive dyskinesia (TD) is a movement disorder that is characterized by uncontrollable, abnormal and repetitive movements of the face, torso and/or other body parts, which may be disruptive and negatively impact patients. The condition is associated with taking certain kinds of mental health medicines (antipsychotics) that help control dopamine receptors in the brain. Taking antipsychotics commonly prescribed to treat mental illnesses such as major depressive disorder, bipolar disorder, schizophrenia and schizoaffective disorder and other prescription medicines (metoclopramide and prochlorperazine) used to treat gastrointestinal disorders are associated with TD. In patients with TD, these treatments are thought to result in irregular dopamine signaling in a region of the brain that controls movement. The symptoms of TD can be severe and are often persistent and irreversible. TD is estimated to affect approximately 600,000 people in the U.S.

About Chorea Associated with Huntington's Disease (HD)Huntington's disease (HD) is a hereditary progressive neurodegenerative disorder in which the loss of certain neurons within the brain causes motor, cognitive and psychiatric symptoms. Symptoms generally appear between the ages of 30 and 50 years and worsen over a 10- to 25-year period. Most people with HD experience chorea, an abnormal involuntary movement disorder, characterized by irregular and unpredictable movements. Chorea can affect various body parts and interfere with motor coordination, gait, swallowing and speech. HD is estimated to affect approximately 41,000 adults in the U.S., with more than 200,000 at risk of inheriting the disease.

About INGREZZA® (valbenazine) CapsulesINGREZZA is the only one-capsule, once-daily selective vesicular monoamine transporter 2 (VMAT2) inhibitor approved by the U.S. Food and Drug Administration for the treatment of adults with tardive dyskinesia and the treatment of chorea associated with Huntington's disease (HD).

INGREZZA, developed by Neurocrine Biosciences, selectively inhibits VMAT2 with no appreciable binding affinity for VMAT1, dopaminergic (including D2), serotonergic, adrenergic, histaminergic or muscarinic receptors. While the specific way INGREZZA works to treat TD and HD chorea is not fully understood, INGREZZA selectively targets VMAT2 to inhibit the release of dopamine, a chemical in the brain that helps control movement. INGREZZA is believed to reduce extra dopamine signaling, which may lead to fewer uncontrollable movements. Additionally, INGREZZA can be taken as one capsule, once daily together with most psychiatric medications such as antipsychotics or antidepressants. INGREZZA dosages approved for use are 40 mg, 60 mg and 80 mg capsules. INGREZZA is not approved in any other dosage form.

Important Information

Approved Uses

INGREZZA® (valbenazine) capsules or INGREZZA® SPRINKLE (valbenazine) capsules are prescription medicines used to treat adults with:

  • movements in the face, tongue, or other body parts that cannot be controlled (tardive dyskinesia).
  • involuntary movements (chorea) of Huntington's disease. INGREZZA or INGREZZA SPRINKLE do not cure the cause of involuntary movements, and do not treat other symptoms of Huntington's disease, such as problems with thinking or emotions.

It is not known if INGREZZA or INGREZZA SPRINKLE is safe and effective in children.


VMAT2 inhibitors, including INGREZZA and INGREZZA SPRINKLE, can cause serious side effects in people with Huntington's disease, including: depression, suicidal thoughts, or suicidal actions. Tell your healthcare provider before you start taking INGREZZA or INGREZZA SPRINKLE if you have Huntington's disease and are depressed (have untreated depression or depression that is not well controlled by medicine) or have suicidal thoughts. Pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. This is especially important when INGREZZA or INGREZZA SPRINKLE is started and when the dose is changed.
