Third Quarter 2022 Financial Results

Net Revenue: Net revenue of $137,000 for the quarter resulted from early product trial with limited market access. Due to the Company’s direct shipping model to hospitals, no wholesaler stocking was expected.

Research and Development (R&D) Expenses: R&D expenses were $22.1 million for the third quarter of 2022, compared to $11.9 million for the same period in 2021. The increased expenses were primarily attributable to an increase in clinical trial costs as the Company expanded its BXCL501 clinical program for Alzheimer’s-related agitation, at-home use, and MDD.

Selling, General and Administrative (SG&A) Expenses: SG&A expenses were $17.1 million for the third quarter of 2022, as compared to $14.9 million for the same period in 2021. The increase was primarily due to personnel and costs related to the launch of IGALMI in the U.S.

Net Loss: BioXcel Therapeutics reported a net loss of $41.8 million for the third quarter of 2022, compared to a net loss of $26.8 million for the same period in 2021. The Company used $31.5 million in operating cash during the third quarter.

As of September 30, 2022, cash and cash equivalents totaled approximately $232.3 million.

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.

About TRANQUILITY II and III

TRANQUILITY II and III are pivotal Phase 3 trials evaluating BXCL501 for the acute treatment of agitation in patients with probable Alzheimer’s disease (AD). The trials include patients who experience agitation across diverse medical settings and across the range of dementia severity. On days when an acute episode of agitation arises, and pharmacological treatment is necessary, the efficacy and safety of dosing is assessed. TRANQUILITY II and III are designed to evaluate the safety and efficacy of BXCL501 for the potential treatment of the full spectrum of agitation associated with AD. Each trial will enroll approximately 150 dementia patients 65 years and older who will self-administer 40mcg or 60mcg of BXCL501 or placebo whenever agitation episodes occur over a three-month period. TRANQUILITY II initiated in December 2021, and will assess patients in assisted living or residential facilities requiring minimal assistance with activities of daily living. TRANQUILITY III will assess patients residing in nursing homes with moderate to severe dementia and require moderate or greater assistance with activities of daily living. The studies will assess agitation as measured by the changes from baseline in the Positive and Negative Syndrome Scale-Excitatory Component (PEC) total score, and include Pittsburgh Agitation Scale (PAS) scores and Clinical Global Impression (CGI). The primary efficacy endpoint for both studies is change in PEC total score from baseline measured at two hours after the initial dose.

About SERENITY III

SERENITY III is a double-blinded, placebo-controlled, pivotal study designed to evaluate BXCL501 60mcg dose for at-home use. This strategic trial decision follows a Type B meeting with the U.S. FDA and observed dose-dependent responses in a prior Phase 1/2b study assessing 20mcg, 60mcg, 80mcg, 120mcg, and 180mcg doses. The first part of SERENITY III is similar to the SERENITY I and II pivotal trials and is designed to assess the efficacy and safety in acutely agitated patients with bipolar disorder or schizophrenia. The primary efficacy endpoint is change from baseline in Positive and Negative Syndrome Scale-Excitatory Component (PEC) total score at two hours after dosing compared to placebo. The second part of SERENITY III is designed to assess safety of 60 mcg doses compared to placebo when self-administered at home. SERENITY III is expected to utilize many of the same investigators and clinical sites as SERENITY I and II.

About Major Depressive Disorder (MDD) Healthy Volunteer Study

The MDD development program has begun with a Phase 1 double-blind, placebo-controlled, multiple ascending dose (MAD) selection trial in healthy volunteers evaluating BXCL501 daily dosing. It is designed to inform dose selection in a future proof-of-concept study evaluating daily BXCL501 dosing in MDD patients. The current study includes cohorts of 18 volunteers who complete seven days of daily dosing. Cohorts of 30mcg, 60mcg, and 80mcg once daily have completed, as have cohorts of twice daily doses; 30mcg in the AM and 60mcg in the PM. Dose escalation is continuing with a cohort testing 40mcg in the AM and 80mcg in PM completing. Additional dose cohorts are planned. Once a maximum tolerable dose (MTD) is determined, escalation will be discontinued and a final cohort will initiate to test a daily maximal well-tolerated dose/ schedule in combination with daily SNRI for one week.
