sNDA submitted seeking approval of IGALMI ® in the at-home (outpatient) setting for the treatment of acute agitation associated with bipolar disorders or schizophrenia sNDA submission timeline supports potential approval as early as year-end 2026 Advancing commercial and launch plans based on third-party market assessment NEW HAVEN, Conn., March 27, 2026 (GLOBE NEWSWIRE) -- BioXcel Therapeutics, Inc. (Nasdaq: BTAI), a biopharmaceutical company built on artificial intelligence (“AI”) to develop transformative medicines in neuroscience, today reported financial results for the fourth quarter and full-year 2025 and provided an update on its late-stage pipeline and commercial launch readiness plans. The Company submitted a supplemental New Drug Application (sNDA) in January to the U.S. Food and Drug Administration (FDA) seeking label expansion of IGALMI for the acute treatment of agitation associated with bipolar disorders and schizophrenia in the at-home setting. The Company is also developing commercial strategy and launch plans for IGALMI in the at-home setting, following completion of a comprehensive market assessment. “2025 was a successful year for our Company, setting the stage for the potential label expansion of IGALMI in the at-home setting and continuing progress with commercial plans for the potential launch of IGALMI,” said Vimal Mehta, Ph.D., Chief Executive Officer of BioXcel Therapeutics. “Our confidence in the substantial market opportunity in the at-home setting, where there are no FDA-approved options available, is reiterated by our recent market opportunity assessment. We also remain focused on advancing our Alzheimer’s dementia program, which is another large market opportunity.” BXCL501 Late-Stage Clinical Programs SERENITY Program IGALMI At-Home sNDA Submission: The Company submitted an sNDA in January to the FDA seeking to expand the IGALMI label for the at-home treatment of acute agitation in bipolar disorder and schizophrenia. The filing is supported by the SERENITY At-Home pivotal Phase 3 trial. Advancing Commercial Preparations: As part of the commercial preparation efforts, the Company appointed Mark Pavao as Interim Chief Commercial Officer to lead the development and execution of the launch plans for IGALMI in the at-home setting. Market Opportunity Assessment: BioXcel Therapeutics is progressing commercial preparation efforts, supported by completion of a third-party market assessment and building on insights to guide a launch plan. The third-party commercial assessment shows the large potential total addressable market for IGALMI in the at-home setting. Analysis of market research revealed up to 86 million addressable annual episodes that may require treatment. Growing Awareness for Self-Administered Treatments at Home: To support commercial preparations through building awareness ahead of potential launch, the Company hosted a virtual roundtable on December 8 featuring leading medical experts discussing advancements in treating acute agitation related to neuropsychiatric conditions, including the potential role of IGALMI outside of the hospital setting. TRANQUILITY PROGRAM TRANQUILITY In-Care Phase 3 Trial: designed as a double-blind, placebo-controlled study to evaluate the efficacy and safety of a 60 mcg dose of BXCL501 for acute treatment of agitation associated with Alzheimer’s dementia in the care setting. The program remains part of the Company’s broader development strategy. FDA has provided feedback on the clinical protocol. The Company has selected a CRO to prepare for trial initiation. Increasing Awareness of Treating Acute Agitation in Alzheimer’s Dementia: The Company sponsored a virtual KOL roundtable on February 27 focused on acute agitation in Alzheimer’s dementia and the unmet need for an FDA-approved treatment option. The event featured leading medical experts and included discussions on the latest developments in the treatment of acute agitation in Alzheimer’s dementia and the potential role of BXCL501. The event reinforced the significant, differentiated, unmet medical need for an approved treatment in this indication. Investigator-Sponsored Trial (IST) Positive Phase 2 Topline Results from Columbia University-Led Study of BXCL501 for Treatment of Opioid Withdrawal, Funded by NIDA: The IST study evaluating BXCL501 for the treatment of opioid withdrawal symptoms in adults with opioid use disorder (OUD) undergoing a methadone taper demonstrated clinical benefits and favorable tolerability profile. These results strengthen the growing body of evidence supporting BXCL501’s clinical benefit across multiple potential indications, reinforcing its potential as a pipeline within a product. Fourth Quarter and Full Year 2025 Financial Results Net revenue from IGALMI ® was $256,000 for the fourth quarter of 2025, compared to $366,000 for the same period in 2024. Net revenue from IGALMI ® was $642,000 for the full year of 2025, compared to $2.3 million for the same period in 2024. The Company is focused on preparing for IGALMI’s launch in the at-home setting and maintaining IGALMI’s brand awareness with minimal commercial resources. Cost of Goods Sold for the fourth quarter of 2025 was $32,000, compared to $832,000, and for the full-year was $164,000, compared to $2.1 million, for the same period in 2024, respectively. The decrease in Cost of Goods Sold for the fourth quarter and full-year ended December 31, 2025 is primarily the result of lower charges for reserves for excess or obsolete inventory compared to the same respective periods in 2024. Research and Development (R&D) expenses were $6.7 million for the fourth quarter of 2025, compared to $5.9 million for the same period in 2024. The increased expenses for the fourth quarter of 2025 were primarily due to the increase in clinical trial expense due to the execution of the SERENITY At-Home pivotal Phase 3 safety trial. R&D expenses were $30.3 million for the full year of 2025, compared to $30.4 million for the full year of 2024. Selling, General and Administrative (SG&A) expenses were $3.8 million for the fourth quarter of 2025, compared to $4.1 million for the same period in 2024. SG&A expenses were $20.5 million for the full year of 2025, compared to $34.5 million for the full year of 2024. The decreased costs for the fourth quarter and the full year 2025 were primarily attributable to a decrease in personnel and related costs, lower legal and professional fees, and lower commercial and marketing costs resulting from the Clinical Reprioritization. Net Loss: BioXcel Therapeutics reported an operating loss of $10.3 million and a net loss of $12.5 million for the fourth quarter of 2025, compared to an operating loss of $10.5 million and net loss of $10.9 million for the same period in 2024. For the full year of 2025, BioXcel Therapeutics reported an operating loss of $50.5 million and a net loss of $69.9 million, compared to an operating loss of $67.2 million and a net loss of $59.6 million for the full year of 2024. Total cash used in operating activities for 2025 totaled approximately $57.6 million, down $14.4 million from 2024 cash used in operating activities of approximately $72.0 million. Cash and cash equivalents and restricted cash totaled $28.8 million as of December 31, 2025. The Company remains in compliance with the covenants in its Credit Agreement.

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.

About the SERENITY At-Home Phase 3 Trial The SERENITY At-Home Phase 3 trial is a double-blind, placebo-controlled study designed to evaluate the safety of a 120-mcg dose of BXCL501 for the acute treatment of agitation associated with bipolar disorders or schizophrenia in the at-home setting. The trial is designed to evaluate 200 patients with a history of agitation episodes residing at home either alone or with caregivers/informants. Patients are self-administering 120-mcg of BXCL501 or placebo when agitation episodes occur over the 12-week trial period, with safety data (adverse events) collected during the trial. In addition, patients or caregivers/informants will complete a modified global impression of severity (mCGIs) and a clinical global impression of change (mCGI-C) two hours after dosing as an exploratory endpoint to evaluate use in the outpatient setting. About the TRANQUILITY In-Care Phase 3 Trial The TRANQUILITY In-Care trial is designed as a double-blind, placebo-controlled study to evaluate the efficacy and safety of a 60-mcg dose of BXCL501 over a 12-week period for agitation associated with Alzheimer’s dementia in the care setting. The trial is expected to enroll approximately 150 patients 55 years and older who have mild, moderate, or severe dementia with mini-mental state examination scores of 0 to 25 and who reside in skilled nursing facilities, memory care units, or assisted living facilities. Patients will self-administer 60-mcg of BXCL501 or placebo when episodic agitation episodes occur over the trial period. The primary endpoint is expected to be a change from baseline in the Positive and Negative Syndrome Scale-Excitatory Component (PEC) total score at two hours post-first dose. Additional PEC and Clinical Global Impressions – Improvement Scale measurements will also be obtained during the trial.
