BioXcel Therapeutics Receives FDA Fast Track Designation for BXCL501 for Acute Treatment of Agitation

Fast track designation for BXCL501 will help facilitate anticipated registration trials in 2019 upon completion of pharmacokinetic (bioavailability) and safety study

NEW HAVEN, Conn., Dec. 27, 2018 -- BioXcel Therapeutics, Inc. (“BTI” or “Company”) (Nasdaq: BTAI), today announced that the U.S. FDA has granted Fast Track Designation for its investigational drug BXCL501, a proprietary sublingual film of dexmedetomidine, for the treatment of acute agitation. BTI is a clinical-stage biopharmaceutical development company utilizing novel artificial intelligence approaches to identify the next wave of medicines across neuroscience and immuno-oncology.

FDA's Fast Track program is designed to provide certain benefits for new drugs that treat serious or life-threatening conditions and demonstrate the potential to address unmet medical needs. The designation provides the opportunity for more frequent meetings with the FDA over the course of development and allows for the potential of rolling submission of individual sections of a New Drug Application for review. If supported by clinical data, this designation allows for the potential of priority review.

Dr. Chetan Lathia, Senior Vice President and Head, Translational Medicine, Clinical Pharmacology and Regulatory Affairs of BTI, commented, “Acute agitation represents a growing healthcare problem and major unmet clinical need with only suboptimal, invasive treatment options with serious potential side effects available to these patients. The fast track designation for BXCL501 reinforces its potential to address unmet medical needs. This milestone also has the potential to accelerate regulatory review and enable us to bring BXCL501 to market more efficiently.”

Dr. Vimal Mehta, Chief Executive Officer of BTI commented, “Fast track designation for BXCL501 highlights FDA’s recognition of our investigational therapy as a possible treatment for acute agitation associated with schizophrenia, bipolar disorder and dementia. This regulatory milestone will help facilitate clinical development and expedite regulatory review of BXCL501, bringing us closer to potentially delivering an optimal therapeutic solution effective for both patients and caregivers.”

BTI is currently conducting a Phase 1 study placebo-controlled, single dose, dose-escalation study of BXCL501. The study is expected to enroll up to 60 healthy adult volunteers across various dosing groups. The primary endpoints are pharmacokinetics and safety, with secondary endpoints including assessment of pharmacodynamics (PD) and the relationship between BXCL501 concentrations and PD endpoints. The Company expects to report top-line data from the study in the first half of 2019.

About BXCL501:

BXCL501 is a first in class, proprietary sublingual film of dexmedetomidine, a selective alpha 2a receptor agonist intended for the treatment of acute agitation. BTI believes that BXCL501 directly targets a causal agitation mechanism and has demonstrated anti-agitation effects in preclinical and clinical studies. It has a well-established regulatory and reimbursement path for the acute treatment of agitation in schizophrenia and bipolar disorder, as demonstrated by Adasuve, a drug previously-approved by the FDA.

About Treatment of Agitation:

Agitation, including the acute treatment of agitation, remains a growing global healthcare burden. The Company estimates the total direct financial cost of all aspects of care for agitation in Alzheimer's disease to be approximately $40 billion per year. The Company believes approximately 5.0 million patients with Alzheimer's disease, schizophrenia and bipolar disorder experience agitation in the U.S. Approximately 1.1 million of these patients experience mild to moderate agitation and represent a potential patient population for treatment with BXCL501.
