BioXcel Therapeutics Prepares to Initiate Pivotal Phase 3 Studies with BXCL501 Following Positive End-of-Phase 2 Meeting with FDA


The Company plans to initiate the pivotal studies by year end, with topline data reported mid-2020

The first sublingual, non-invasive acute treatment candidate designed for agitation in neuropsychiatric diseases

NEW HAVEN, Conn., Dec. 03, 2019 (GLOBE NEWSWIRE) -- BioXcel Therapeutics (“BTI” or “Company”) (Nasdaq: BTAI), a clinical-stage biopharmaceutical company utilizing artificial intelligence approaches to identify and advance the next wave of medicines in neuroscience and immuno-oncology, today announced it has reached a general agreement with the U.S. Food and Drug Administration (FDA) on the key elements of the designs for its SERENITY (Sub-Lingual DExmedetomidine in Agitation Associated With SchizophRENIa and Bipolar Disorder STudY) program, two Phase 3 studies of BXCL501 for the acute treatment of agitation in patients with schizophrenia and bipolar disorder. Following the successful completion of its end-of-phase 2 meeting with the FDA, the Company plans to initiate the SERENITY studies by year end, with available topline results expected in mid-2020.

“Our pivotal Phase 3 studies are designed to support the regulatory approval of BXCL501 as a non-injectable, acute treatment for agitation in patients with schizophrenia and bipolar disorder,” commented Vimal Mehta, Chief Executive Officer of BTI. “There is significant need for an easy-to-use, safe and fast acting therapy for the 8 million people in the U.S. that suffer from agitation associated with neuropsychiatric diseases. We’re highly encouraged by our interactions with the FDA, and are one step closer to providing physicians with a potentially more effective and easier-to-use therapy to help safely manage their patients.”

The SERENITY studies closely follow the Company’s successful Phase 1b trial in 135 schizophrenia patients, where there were statistically significant, clinically meaningful rapid and durable reductions in PEC score at 120 and 180 microgram doses and acceptable safety profile. For the Phase 3 program, which will take place in many of the centers that participated in the Phase 1b trial, there will be two randomized, double-blinded, placebo-controlled, adaptive trials of up to 750 patients 18 to 75 years of age. SERENITY I will enroll patients with agitation associated with schizophrenia, with each arm receiving either BXCL501 at 120 micrograms, 180 micrograms, or placebo. SERENITY II will evaluate patients with agitation associated with bipolar disorder, also with each of three arms receiving either BXCL501 at 120 micrograms, 180 micrograms, or placebo.

The primary endpoint of both trials will be the reduction of symptoms of acute agitation in patients with schizophrenia and bipolar disorder using the Positive and Negative Syndrome Scale, measuring the Excited Component (PEC) change from baseline compared to placebo. The key secondary endpoint includes determining the earliest time where an effect on agitation is apparent as measured by the change from baseline in PEC total score.

About Agitation in Neuropsychology

Agitation is a common and costly (approximately $40 billion per year health care burden) symptom associated with a number of psychiatric conditions, including schizophrenia and bipolar disorder. It is estimated that approximately 19 million people are at risk of agitation and 8.3 million in the U.S. suffer from agitation each year. Early identification and prompt intervention to relieve agitation are essential to avoid symptomatic escalation and emergence of aggression. Recent onsensus guidelines emphasize the need for non-coercive management strategies to protect the therapeutic alliance between patients and their healthcare providers—an alliance that is critical for the effective management of chronic psychiatric conditions. A non-invasive therapy that causes rapid symptom relief and de-escalates agitation is necessary to avoid the costly and traumatic use of coercive techniques, like physical restraint and seclusion, which require admission and prolonged hospitalization.



About the PEC (PANSS-EC or the Positive and Negative Syndrome Scale-Excitatory Component) Score for Agitation

The PEC score is a validated regulatory endpoint for measuring acute agitation in schizophrenia and bipolar patients. This scale is used in clinical research to rate the severity of a patient’s acute agitation. The PEC score is comprised of 5 elements associated with agitation: poor impulse control, tension, hostility, uncooperativeness, and excitement; each scored 1 (minimum) to 7 (maximum). The PEC is the sum of these 5 subscales and thus ranges from 5 to 35.


About BXCL501

BXCL501 is a potential first-in-class, proprietary sublingual thin film of dexmedetomidine, a selective alpha-2a receptor agonist for the treatment of acute agitation. BTI believes that BXCL501 directly targets a causal agitation mechanism, and the Company has observed anti-agitation effects in multiple clinical studies across neuropsychiatric indications. BXCL501 has also been granted Fast Track Designation by the U.S. Food and Drug Administration for the acute treatment of agitation.

A Phase 1b safety and efficacy study of BXCL501 yielded positive dose-response data. BTI plans to initiate by year end the SERENITY (Sub-Lingual DExmedetomidine in Agitation Associated With SchizophRENIa and Bipolar Disorder STudY) program, which will evaluate BXCL501 for the acute treatment of agitation resulting from schizophrenia and bipolar disorder. The Company also plans to initiate a Phase 1b/2 study of BXCL501 in patients with agitation associated with Dementia in the fourth quarter of 2019, with topline data expected in the first half of 2020.
