Company plans to initiate SERENITY At-Home pivotal Phase 3 safety trial with 120 mcg dose following recent meeting with FDA
No FDA-approved therapies for acute treatment of agitation associated with bipolar disorders or schizophrenia in the home setting
NEW HAVEN, Conn., April 22, 2024 (GLOBE NEWSWIRE) -- BioXcel Therapeutics, Inc. (Nasdaq: BTAI), a biopharmaceutical company utilizing artificial intelligence to develop transformative medicines in neuroscience and immuno-oncology, today announced additional details regarding the planned design of its SERENITY At-Home Phase 3 trial*to evaluate BXCL501, the Company’s investigational, proprietary, orally dissolving film formulation of dexmedetomidine, as a potential acute treatment for agitation associated with bipolar disorders or schizophrenia in the home setting. The Company’s plan to conduct this trial using a 120 mcg dose is based on feedback received from the U.S. Food and Drug Administration (FDA) following the recent receipt of agency minutes from the Type C meeting held on March 6, 2024.
“BXCL501 is already FDA-approved as IGALMI™ at the 120 mcg dose for the acute treatment of agitation associated with schizophrenia or bipolar I or II disorder in adults under healthcare provider supervision, based on efficacy and safety data that we previously generated in SERENITY I and II,” said Vincent O’Neill, M.D., Chief of Product Development and Medical Officer of BioXcel Therapeutics. “We are now striving to make BXCL501 available to millions of additional patients by collecting the data necessary to potentially expand its label for outpatient use at home, where nearly 60% of the episode volume occurs.”
SERENITY At-Home Pivotal Phase 3 Trial Design Summary
- The SERENITY At-Home Phase 3 trial is designed as a double blind, placebo-controlled study to evaluate the safety and efficacy of a 120 mcg dose of BXCL501 over a 12-week period.
- The outpatient trial is expected to enroll a total of approximately 200 patients with agitation associated with bipolar disorder or schizophrenia.
- Patients will self-administer 120 mcg of BXCL501 or placebo when agitation episodes occur over the trial period.
- The primary objective is safety with efficacy measures as exploratory endpoints to evaluate use in the outpatient setting.
In addition, the Company expects to enroll approximately 30 patients in a separate study to evaluate the correlation between patient-reported or informant-reported efficacy with trained rater-reported efficacy using Positive and Negative Syndrome Scale-Excitatory Component (PEC) measurements.
A corporate presentation, including information on the SERENITY program, is available on the Investors section of the Company’s website: bioxceltherapeutics.com.

About IGALMI™ (dexmedetomidine) sublingual film
INDICATION
IGALMI™ (dexmedetomidine) sublingual film is a prescription medicine, administered under the supervision of a health care provider, that is placed under the tongue or behind the lower lip and is used for the acute treatment of agitation associated with schizophrenia and bipolar disorder I or II in adults. The safety and effectiveness of IGALMI has not been studied beyond 24 hours from the first dose. It is not known if IGALMI is safe and effective in children.
IMPORTANT SAFETY INFORMATION
IGALMI can cause serious side effects, including:
- Decreased blood pressure, low blood pressure upon standing, and slower than normal heart rate, which may be more likely in patients with low blood volume, diabetes, chronic high blood pressure, and older patients. IGALMI is taken under the supervision of a healthcare provider who will monitor vital signs (like blood pressure and heart rate) and alertness after IGALMI is administered to help prevent falling or fainting. Patients should be adequately hydrated and sit or lie down after taking IGALMI and instructed to tell their healthcare provider if they feel dizzy, lightheaded, or faint.
- Heart rhythm changes (QT interval prolongation). IGALMI should not be given to patients with an abnormal heart rhythm, a history of an irregular heartbeat, slow heart rate, low potassium, low magnesium, or taking other drugs that could affect heart rhythm. Taking IGALMI with a history of abnormal heart rhythm can increase the risk of torsades de pointes and sudden death. Patients should be instructed to tell their healthcare provider immediately if they feel faint or have heart palpitations.
- Sleepiness/drowsiness. Patients should not perform activities requiring mental alertness, such as driving or operating hazardous machinery, for at least 8 hours after taking IGALMI.
- Withdrawal reactions, tolerance, and decreased response/efficacy. IGALMI was not studied for longer than 24 hours after the first dose. Physical dependence, withdrawal symptoms (e.g., nausea, vomiting, agitation), and decreased response to IGALMI may occur if IGALMI is used longer than 24 hours.
The most common side effects of IGALMI in clinical studies were sleepiness or drowsiness, a prickling or tingling sensation or numbness of the mouth, dizziness, dry mouth, low blood pressure, and low blood pressure upon standing.
These are not all the possible side effects of IGALMI. Patients should speak with their healthcare provider for medical advice about side effects.
Patients should tell their healthcare provider about their medical history, including if they suffer from any known heart problems, low potassium, low magnesium, low blood pressure, low heart rate, diabetes, high blood pressure, history of fainting, or liver impairment. They should also tell their healthcare provider if they are pregnant or breastfeeding or take any medicines, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Patients should especially tell their healthcare provider if they take any drugs that lower blood pressure, change heart rate, or take anesthetics, sedatives, hypnotics, and opioids.
Everyone is encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088. You can also contact BioXcel Therapeutics, Inc. at 1-833-201- 1088 or medinfo@bioxceltherapeutics.com.

About BXCL501
In indications other than those approved by the U.S. Food and Drug Administration (FDA) as IGALMI™ (dexmedetomidine) sublingual film, BXCL501 is an investigational proprietary, orally dissolving film formulation of dexmedetomidine, a selective alpha-2 adrenergic receptor agonist. BioXcel Therapeutics believes that BXCL501 potentially targets an important mediator of agitation, and the Company has observed anti-agitation results in multiple clinical trials across several neuropsychiatric disorders. BXCL501 is under investigation by BioXcel Therapeutics for the acute treatment of agitation associated with dementia due to probable Alzheimer’s disease and for the acute treatment of agitation associated with bipolar I or II disorder or schizophrenia in the at-home setting. The safety and efficacy of BXCL501 for these investigational uses have not been established. BXCL501 has been granted Breakthrough Therapy designation by the FDA for the acute treatment of agitation associated with dementia and Fast Track designation for the acute treatment of agitation associated with schizophrenia, bipolar disorders, and dementia.
About the Positive and Negative Syndrome Scale-Excitatory Component Score (PEC or PANSS-EC)
The PEC total score is a validated endpoint for use in clinical research to quantify the severity of a patient’s acute agitation. The PEC rating evaluates 5 elements associated with agitation: poor impulse control, tension, hostility, uncooperativeness, and excitement; each scored 1 (minimum) to 7 (maximum). The PEC total score is the sum of these 5 elements and thus ranges from 5 to 35.
