Company to host investor conference call on April 6, 2022 at 8:30 a.m. ET
NEW HAVEN, Conn., April 06, 2022 (GLOBE NEWSWIRE) — BioXcel Therapeutics, Inc. (Nasdaq: BTAI), a biopharmaceutical company utilizing artificial intelligence (AI) approaches to identify and develop transformative medicines in neuroscience and immuno-oncology, today announced that the U.S. Food and Drug Administration (FDA) has approved IGALMI™ (dexmedetomidine) sublingual film for the acute treatment of agitation associated with schizophrenia or bipolar I or II disorder in adults.1 IGALMI can be self-administrated by patients under the supervision of a healthcare provider.1 The Company is prepared to launch IGALMI in the U.S. in the second quarter of 2022.
“There are large numbers of patients who experience agitation associated with schizophrenia and bipolar disorders, and this condition has been a long-standing challenge for healthcare professionals to treat,” said Dr. John Krystal, M.D., the Robert L. McNeil, Jr. Professor of Translational Research and Chair of the Department of Psychiatry at Yale School of Medicine. “The approval of IGALMI, a self-administered film with a desirable onset of action, represents a milestone moment. It provides healthcare teams with an innovative tool to help control agitation. As clinicians, we welcome this much-needed new oral treatment option.”
An estimated 7.3 million people in the U.S. are diagnosed with schizophrenia or bipolar disorders.2-3 Up to a quarter of these people experience agitation, with episodes that can occur 10 to 17 times annually, totaling up to 25 million agitation episodes for these two patient populations per year.2-4 Agitation episodes are associated with a significant burden for patients, caregivers, and the healthcare system.5
“IGALMI is the first new acute treatment for schizophrenia or bipolar disorder-associated agitation in nearly a decade and represents a differentiated approach to helping patients manage this difficult and debilitating symptom,”6-7 said Vimal Mehta, Ph.D., CEO of BioXcel Therapeutics. “With this landmark achievement of our first approved drug, we have taken a monumental step toward our mission of bringing transformative medicines in neuroscience to patients using our AI platform. We are deeply grateful to our clinical trial participants, healthcare providers, researchers, and employees for contributing to this important new therapy. We believe IGALMI has significant market-changing potential, and we are excited to execute on our commercial launch plans in the U.S. this quarter.”
The FDA approval of IGALMI is based on data from two pivotal randomized, double-blinded, placebo-controlled, parallel group Phase 3 trials evaluating IGALMI for the acute treatment of agitation associated with schizophrenia (SERENITY I) or bipolar I or II disorder (SERENITY II).1
The primary endpoint was the mean change from baseline in the Positive and Negative Syndrome Scale-Excited Component (PEC) total score assessed at 2 hours following dosing. The key secondary endpoint was the earliest time where efficacy, measured by the change from baseline in PEC score, was statistically separated from placebo.1 PEC is an investigator-rated instrument for measuring agitation in patients that evaluates five elements associated with agitation: poor impulse control, tension, hostility, uncooperativeness, and excitement.1
In both trials, IGALMI met the primary endpoint at two hours after the first dose in patients treated with the 120 mcg and 180 mcg doses, demonstrating statistically significant improvements from baseline. IGALMI also met the key secondary endpoint, demonstrating a rapid onset of action, with statistically significant separation from placebo observed at 20 minutes for both the 180 mcg and 120 mcg doses in SERENITY II and 20 minutes and 30 minutes in SERENITY I, respectively.1
The most common adverse reactions (incidence ≥5% and at least twice the rate of placebo) were somnolence (drowsiness and feeling sleepy), paresthesia or oral hypoesthesia, dizziness, dry mouth, hypotension (low blood pressure) and orthostatic hypotension. All adverse drug reactions were mild to moderate in severity. While IGALMI did not exhibit any treatment-related serious adverse effects (SAEs) in Phase 3 studies, it may cause notable side effects including hypotension, orthostatic hypotension and bradycardia, QT interval prolongation, and somnolence.1
Data from the pivotal Phase 3 SERENITY II trial evaluating IGALMI in bipolar disorders were published in the Journal of the American Medical Association (JAMA) on February 22, 2022.8

About Agitation Associated with Schizophrenia and Bipolar Disorder
Agitation is a common and difficult-to-manage symptom associated with bipolar I or II or schizophrenia. Early identification and prompt intervention to relieve agitation are essential to avoid symptomatic escalation and the emergence of aggression. Expert consensus best-practice guidelines have recommended that agitation should be treated by a combination of behavioral calming techniques, verbal de-escalation, and medications that are voluntarily accepted by patients without coercion. The goal of using medication is to calm the patient so that he or she can be more accurately assessed by clinicians. Medication used in this manner is consistent with current guidelines, which state that the proper endpoint of medication administration is calming without inducing sleep. This approach may help avoid the costly and traumatic use of coercive techniques like physical restraint and seclusion, which may result in admission and prolonged hospitalization.5

INDICATION
IGALMI is indicated for the acute treatment of agitation associated with schizophrenia or bipolar I or II disorder in adults. Limitations of Use: The safety and effectiveness of IGALMI have not been established beyond 24 hours from the first dose.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Hypotension, Orthostatic Hypotension, and Bradycardia: IGALMI causes dose-dependent hypotension, orthostatic hypotension, and bradycardia. Because IGALMI decreases sympathetic nervous system activity, hypotension and/or bradycardia may be more pronounced in patients with hypovolemia, diabetes mellitus, or chronic hypertension, and in geriatric patients. Avoid use of IGALMI in patients with hypotension, orthostatic hypotension, advanced heart block, severe ventricular dysfunction, or history of syncope. After IGALMI administration, patients should be adequately hydrated and should sit or lie down until vital signs are within normal range. If a patient is unable to remain seated or lying down, precautions should be taken to reduce the risk of falls. Ensure that a patient is alert and not experiencing orthostatic hypotension or symptomatic hypotension prior to allowing them to resume ambulation.
QT Interval Prolongation: IGALMI prolongs the QT interval. Avoid use of IGALMI in patients at risk of torsades de pointes or sudden death, including those with known QT prolongation, a history of other arrhythmias, symptomatic bradycardia, hypokalemia, or hypomagnesemia, and in patients receiving other drugs known to prolong the QT interval.
Somnolence: IGALMI can cause somnolence. Patients should not perform activities requiring mental alertness, such as operating a motor vehicle or operating hazardous machinery, for at least eight hours after taking IGALMI.
Risk of Withdrawal Reactions, Tolerance, and Tachyphylaxis: IGALMI was not studied for longer than 24 hours after the first dose. There may be a risk of physical dependence, a withdrawal syndrome, tolerance, and/or tachyphylaxis if IGALMI is used in a manner other than indicated.
ADVERSE REACTIONS
The most common adverse reactions (incidence ≥5% and at least twice the rate of placebo) were somnolence, paresthesia or oral hypoesthesia, dizziness, dry mouth, hypotension, and orthostatic hypotension.
DRUG INTERACTIONS
Drugs That Prolong the QT Interval: Avoid use.
Anesthetics, Sedatives, Hypnotics, and Opioids: Concomitant use may cause enhanced CNS-depressant effects. Reduction in dosage of IGALMI or the concomitant medication should be considered.
USE IN SPECIFIC POPULATIONS
Hepatic Impairment and Geriatric Patients (≥65 years old): A lower dose is recommended in patients with hepatic impairment and geriatric patients. See the full Prescribing Information for the recommended dosage depending on the agitation severity.
Please see full Prescribing Information.
