BioXcel Therapeutics Reports Financial Results for the Fourth Quarter and Full Year 2023

Provides update on two late-stage clinical programs for BXCL501 for potential treatment of agitation

Recently completed meetings with U.S. Food and Drug Administration for TRANQUILITY and SERENITY programs

Conference call and webcast set for 8:00 a.m. ET today

NEW HAVEN, Conn., March 12, 2024 (GLOBE NEWSWIRE) — BioXcel Therapeutics, Inc. (Nasdaq: BTAI), a biopharmaceutical company utilizing artificial intelligence to develop transformative medicines in neuroscience and immuno-oncology, today provided an update on its late-stage TRANQUILITY and SERENITY clinical programs. In addition, the Company reported its financial results for the fourth quarter and full year 2023.

“We believe our late-stage programs evaluating BXCL501 for acute agitation associated with Alzheimer’s dementia, bipolar disorders, and schizophrenia represent groundbreaking opportunities to bring much-needed treatment options to large numbers of patients and caregivers,” said Vimal Mehta, Ph.D., CEO of BioXcel Therapeutics. “We are pleased to be advancing the clinical development paths for TRANQUILITY and SERENITY, and plan to focus our resources on these high-priority programs.”

TRANQUILITY Program:
Evaluating 60 mcg dose of BXCL501 for agitation associated with Alzheimer’s dementia (AAD)

• On February 20, 2024, the Company held a Type B/Breakthrough Therapy designation meeting with FDA.
• Based on the FDA’s feedback, the Company plans to generate additional Phase 3 efficacy and safety data in care facilities to expand the database beyond the 70 patients who have already been treated with 60 mcg of BXCL501 in TRANQUILITY I and II to date. The Company plans to generate these data in a variety of relevant care settings and across severity of dementia using the Positive and Negative Syndrome Scale-Excitatory Component (PEC) as the primary efficacy measure, as used in the prior TRANQUILITY II study. 
  • The Company announced in November 2023 that it was planning to conduct a Phase 3 trial in the at-home setting, with safety as the primary objective (TRANQUILITY At Home).  Given the priority to expand the database to generate additional efficacy data in care facilities, the Company is re-evaluating the timing for initiating TRANQUILITY At Home. 
• Given no prior regulatory precedent for episodic treatment of agitation in AD patients, the Company plans to engage with the FDA regarding the requirement for collection of long-term safety data.
• The Company expects to provide further guidance regarding program plans following receipt of final meeting minutes from FDA.

SERENITY Program:
Evaluating potential at-home use of 120 mcg of BXCL501 for agitation associated with bipolar disorders or schizophrenia

• On March 6, 2024, the Company held a Type C meeting with FDA.
• Based on FDA feedback, Company plans to conduct a Phase 3 trial by amending the SERENITY III protocol to evaluate the 120 mcg dose of BXCL501 (an approved dose of IGALMI™) in the at-home setting, with safety as the primary objective and efficacy measures as exploratory endpoints.
• The Company expects to provide further guidance regarding program plans following receipt of final meeting minutes from FDA.

Fourth Quarter and Full Year 2023 Financial Results

Net Revenue: Net revenue from IGALMI was $376,000 for the fourth quarter of 2023, compared to $238,000 for the same period in 2022.

Net revenue from IGALMI was $1.4 million for the full year of 2023, compared to $375,000 for 2022.

Research and Development (R&D) Expenses: R&D expenses were $9.9 million for the fourth quarter of 2023, compared to $32.5 million for the same period in 2022.

R&D expenses were $84.3 million for the full year of 2023, compared to $91.2 million for the full year of 2022. The decreased expenses for both the fourth quarter and the full year were primarily attributable to a decrease in clinical trial activity associated with the wind down of the SERENITY III and TRANQUILITY II studies, a decrease in chemical, manufacturing, and control (CMC) costs, and a decrease in personnel related to the Reprioritization.

Selling, General and Administrative (SG&A) Expenses: SG&A expenses were $9.6 million for the fourth quarter of 2023, compared to $20.7 million for the same period in 2022.

SG&A expenses were $83.4 million for the full year 2023, compared to $68.8 million for 2022. The increased costs for the full year were primarily attributable to an increase in legal and professional fees, costs associated with increased personnel, and related costs to support the commercialization of IGALMI in the U.S. prior to the Reprioritization.

Net Loss: BioXcel Therapeutics had a net loss of $22.3 million for the fourth quarter of 2023, compared to a net loss of $54.8 million for the same period in 2022. For the full year of 2023, BioXcel Therapeutics reported a net loss of $179.0 million, compared to a net loss of $165.8 million for the full year of 2022. The loss for the 2023 year includes approximately $18.6 million in non-cash stock-based compensation. Total cash expenditures for 2023 totaled approximately $155.0 million.

Cash and cash equivalents totaled $65.2 million on December 31, 2023, compared to $193.7 million on December 31, 2022. The Company estimates that its current cash and cash equivalents will fund its operations through mid-2024. This estimated cash runway does not include potential additional capital that may become available under the amendments to the strategic financing agreements or resulting from any potential financing activities that may be undertaken by the Company.

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.
