First Quarter 2021 and Recent Highlights

BXCL501-Neuroscience Program

BXCL501 is an investigational, proprietary, orally dissolving thin film formulation of dexmedetomidine, a selective alpha-2 adrenergic receptor agonist, designed for the treatment of agitation and opioid withdrawal symptoms. The Company believes BXCL501 may directly target a causal agitation mechanism.

• Reported positive topline results from the Phase 1b/2 TRANQUILITY trial of BXCL501 for the acute treatment of agitation associated with dementia.
• Granted Breakthrough Therapy designation by the U.S. Food and Drug Administration ("FDA") to BXCL501 for the acute treatment of agitation associated with dementia.
• End of Phase 2 meeting with the FDA planned in 2Q 2021 to discuss registrational trial.
• Recruitment in 40 mcg supplemental dose cohort of BXCL501 in TRANQUILITY expansion study is progressing well.
• Completed its New Drug Application ("NDA") submission to the FDA for BXCL501 for the acute treatment of agitation associated with schizophrenia and the acute treatment of agitation associated with bipolar disorders I and II.
• Plan to submit Marketing Authorization Application ("MAA") with European Medicines Agency ("EMA") using SERENITY I and II data for the acute treatment of agitation associated with schizophrenia and bipolar disorders I and II in 2H 2021.
• Reported results from the Phase 1b/2 study of BXCL501 for the treatment of opioid withdrawal symptoms. Primary safety endpoints were met, and numerically improved retention rates, a secondary endpoint, were demonstrated in multiple BXCL501 dose cohorts.
• PLACIDITY enrollment was voluntarily paused to assess challenges posed in opening relevant clinical sites and enrolling delirium patients in the ICU setting, including as a result of the burden COVID-19 has placed on ICUs.
• Strengthened BXCL501 IP portfolio with issuance of two Japanese patents - Patent No. 6868698, directed to methods of treating agitation, which will expire no earlier than 2037, and Patent No. 1681960, directed to film design, which will expire no earlier than 2041.

Commercial Highlights

• Launched "Boiling Point" educational campaign to raise awareness about agitation associated with schizophrenia and bipolar disorder and its impact on patients and clinicians.
• Completed U.S. market assessment initiatives and design of sales force size and structure.

Medical Affairs Initiatives

• Deployed the Medical Science Liaison and Medical Manage Care teams and have begun scientific and medical-to-medical exchange with healthcare professionals and payers, respectively.
• Presented two posters covering data from the pivotal Phase 3 SERENITY trials in patients with acute agitation associated with schizophrenia and bipolar disorders I and II at the American Psychiatric Association ("APA") Annual Meeting.

BXCL701-Immuno-Oncology Program

BXCL701 is an orally-delivered small molecule, immunomodulator designed to inhibit dipeptidyl peptidase ("DPP") 8/9 and block immune evasion by targeting Fibroblast Activation Protein ("FAP"). It has shown single agent anti-tumor activity in melanoma and safety has been evaluated in more than 700 healthy subjects and cancer patients.

• The adenocarcinoma cohort of the ongoing Phase 1b/2 trial of BXCL701 and pembrolizumab (KEYTRUDA^®) in aggressive forms of prostate cancer has met its efficacy bar to move to stage two. The trial will now continue to full enrollment and more complete efficacy data are expected to be presented at a scientific conference later this year.
• Granted orphan drug designation by the FDA to BXCL701 for the treatment of soft tissue sarcoma.

Corporate Highlights

• Appointed June Bray to the Company's Board of Directors. Ms. Bray brings over forty years of extensive U.S. and global regulatory experience across all therapeutics areas, including psychiatry and neurology.
• Appointed Javier Rodriguez as Chief Legal Officer and Corporate Secretary. Mr. Rodriguez brings over 20 years of extensive strategic and legal experience within the biopharmaceutical industry.

First Quarter 2021 Financial Results

Research and Development Expenses: Research and development expenses were $14.7 million during the first quarter of 2021, as compared to $12.4 million for the same period in 2020. The higher expenses were primarily attributable to an increase in personnel and related costs necessary to enlarge our development and medical teams. In addition, we experienced increased professional fees in conjunction with higher consulting fees and CMC costs related to BXCL501, as well as increased costs related to our RELEASE clinical trial. These increases were offset in part by a decrease in SERENITY I and II clinical trial costs.

General and Administrative Expenses: General and administrative expenses were $11.6 million for the first quarter of 2021, as compared to $2.6 million for the same period in 2020. The increase was primarily due to higher personnel related costs as well as costs related to our expansion in preparation of the potential commercial launch of BXCL501 in the U.S., and increased legal, professional fees, and insurance costs.

Net Loss: BioXcel reported a net loss of $26.4 million for the first quarter of 2021, compared to a net loss of $14.9 million for the same period in 2020.

The first quarter 2021 results include approximately $5.6 million in non-cash stock-based compensation costs, compared to non-cash stock-based compensation of $776,000 for the same period in 2020.

As of March 31, 2021, cash and cash equivalents totaled approximately $194 million.
