Development Pipeline  
BXCL501, a proprietary, sublingual film formulation of dexmedetomidine, has received Breakthrough Therapy and Fast Track designation for the acute treatment of agitation associated with dementia.

• Alzheimer’s Disease-related Agitation: TRANQUILITY program is designed to evaluate BXCL501 for the acute treatment of Alzheimer’s-related agitation, where up to 100 million agitation episodes are estimated to occur in the U.S. annually.^1*
  • TRANQUILITY II: Trial is fully enrolled; nearing completion of three-month observation period in a few patients in assisted living facilities (ALFs) and residential settings.
    • Data cleaning and verification in progress.
    • Top-line data from pivotal trial expected in Q2 2023.
  • TRANQUILITY III: Continuing enrollment of patients with moderate to severe dementia in nursing homes.
    
    
• Bipolar or Schizophrenia-related Agitation (At-Home Use): SERENITY III program is designed to evaluate BXCL501 for use at home, where up to 23 million agitation episodes are estimated to occur in the U.S. annually.^1-3*
  

SERENITY III consists of two parts:

• Part 1: Assessing the efficacy and safety of 60mcg dose in acutely agitated patients with bipolar I or II disorder or schizophrenia in a supervised setting, similar to SERENITY I and II.
  • More than 90% of patients enrolled and complete enrollment is imminent.
  • Top-line efficacy data from pivotal trial expected in Q2 2023.
• Part 2: Evaluating the safety of self-administration of 60mcg dose at-home.
  • Expect to initiate trial in Q2 2023.
    

• Adjunctive Treatment for Major Depressive Disorder (MDD) for At-Home Use: Phase 1b Multiple Ascending Dose (MAD) trial is designed to test safety and tolerability of daily dosing of BXCL501 to inform proof-of-concept (POC) trial dose selection in combination with selective serotonin - or serotonin-norepinephrine reuptake inhibitors (SSRIs or SNRIs, respectively) in MDD patients. Over 300 million antidepressant prescriptions are filled annually in the U.S.,^5* and current treatments are limited by slow onset of action and incomplete responses.
  
  
  • Enrollment has been completed; cohorts have received either daily or twice-daily dosing regimens for seven days, including a final cohort in combination with an SNRI.

Fourth Quarter and Full Year 2022 Financial Results

Net Revenue: Net revenue was approximately $238,000 for the quarter and $375,000 for the full year 2022, which resulted from early product trials and reflects limited market access. Due to the Company’s direct shipping model to hospitals, wholesaler stocking was neither expected nor occurred.

Research and Development (R&D) Expenses: R&D expenses were $32.5 million for the fourth quarter of 2022, compared to $12.5 million for the same period in 2021.

R&D expenses were $91.2 million for the full year 2022, compared to $52.7 million for the same period in 2021. The increased expenses for both the fourth quarter and the full year were primarily attributable to an increase in clinical trial costs related to multiple major pivotal BXCL501 clinical programs.

Selling, General and Administrative (SG&A) Expenses: SG&A expenses were $20.7 million for the fourth quarter of 2022, as compared to $13.6 million for the same period in 2021.

SG&A expenses were $68.8 million for the full year 2022, as compared to $54.2 million for 2021. The increased costs for both the fourth quarter and full year were primarily due to personnel and costs related to the launch of IGALMI in the U.S.

Net Loss: BioXcel Therapeutics had a net loss of $54.8 million for the fourth quarter of 2022, compared to a net loss of $26.1 million for the same period in 2021. For the full year, BioXcel Therapeutics reported a net loss of $165.8 million, compared to a net loss of $106.9 million for the same period in 2021. The loss for the year includes approximately $17.3 million in non-cash stock-based compensation. Total cash expenditures for 2022 totaled approximately $135.3 million.

Cash and cash equivalents totaled $193.7 million at December 31, 2022, compared to $233.0 million at December 31, 2021. To date in the first quarter of 2023, the Company utilized its existing at-the-market equity facility and received net proceeds of approximately $24 million.

The Company believes that full execution of our strategic financing with Oaktree and Qatar Investment Authority would result in a cash runway into 2025 for the Company.

About IGALMI™ (dexmedetomidine) sublingual film

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 

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.
