First patient randomized in SERENITY At-Home trial of BXCL501 for acute treatment of agitation associated with bipolar disorders or schizophrenia
Received FDA feedback on protocol for TRANQUILITY In-Care trial of BXCL501 for agitation associated with Alzheimer’s dementia (AAD)
Estimated 140 million annual acute agitation episodes associated with these conditions 1-3
NEW HAVEN, Conn., Nov. 12, 2024 (GLOBE NEWSWIRE) -- BioXcel Therapeutics, Inc. (Nasdaq: BTAI), a biopharmaceutical company utilizing artificial intelligence to develop transformative medicines in neuroscience, today announced the achievement of clinical and regulatory progress for its pivotal Phase 3 clinical trials of BXCL501 for the acute treatment of agitation associated with bipolar disorders or schizophrenia (SERENITY At-Home) and agitation associated with Alzheimer’s dementia (TRANQUILITY In-Care). There are no FDA-approved acute therapies for these conditions.
“We are pleased with the progress on our late-stage trials, which leverage our extensive clinical development experience,” said Vincent O’Neill, M.D., Chief of Product Development and Medical Officer of BioXcel Therapeutics. “With SERENITY At-Home, we are seeking to make BXCL501, which is currently approved under healthcare provider supervision as IGALMI™, available to millions of additional patients by potentially expanding its label for treating bipolar or schizophrenia-related agitation in the home. With TRANQUILITY In-Care, we have a unique opportunity in AAD, for which there is no U.S. regulatory precedent for episodic treatment. We look forward to continuing our development of BXCL501 for these critical unmet medical needs.”
SERENITY At-Home Pivotal Phase 3 trial
- Designed to evaluate the safety of a 120 mcg dose of BXCL501 in the at-home setting for agitation associated with bipolar disorders or schizophrenia
- The first patient has been randomized.
- The Company announced trial initiation on September 5, 2024, with an expected trial duration of 9 to 12 months.
- The double-blind, placebo-controlled, 12-week outpatient trial is expected to enroll approximately 200 patients residing at home.
TRANQUILITY In-Care Pivotal Phase 3 trial
- Designed to evaluate the efficacy and safety of a 60 mcg dose of BXCL501 for AAD over a 12-week period
- Received feedback from the U.S. Food and Drug Administration on proposed protocol
- The double-blind, placebo-controlled study trial is expected to enroll a total of approximately 150 patients aged 55 years and older across the spectrum of Alzheimer’s disease severity with mild, moderate, and severe dementia with mini-mental state examination (MMSE) scores of 0 to 25 who reside in skilled nursing facilities, memory care units, or assisted living facilities.
- The trial is expected to enroll patients with episodic agitation, with patients self-administering 60 mcg of BXCL501 or placebo when agitation episodes occur over the trial period.
- The planned primary endpoint is a change from baseline in the Positive and Negative Syndrome Scale-Excitatory Component (PEC) total score at two hours post-first dose. This is the same endpoint used in previous TRANQUILITY trials and in studies that supported the FDA approval of IGALMI™ (dexmedetomidine) sublingual film.
- Continued efficacy evaluations are expected to be conducted through performing additional PEC and complementary efficacy measures, including the global impression of change in agitation.

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.
