BioXcel Therapeutics Completes Dosing Two Cohorts of Agitated Schizophrenia Patients with BXCL501 in a Phase 2 Efficacy Trial


Total of 96 agitated patients and healthy volunteers have received multiple doses of BXCL501, a proprietary sublingual thin film

On track to announce top line results from Phase 2 efficacy trial in 3Q 2019

Planning to initiate first Phase 3 pivotal trial in 4Q 2019

NEW HAVEN, Conn., June 10, 2019 (GLOBE NEWSWIRE) -- BioXcel Therapeutics, Inc. (“BTI” or the “Company”) (Nasdaq: BTAI), announced today that it has completed dosing of the first two cohorts of agitated schizophrenia patients in its Phase 2 efficacy trial of BXCL501, the Company’s proprietary sublingual thin-film formulation of dexmedetomidine (“Dex”). BTI plans to use the results from this study to pursue two planned Phase 3 pivotal trials in agitated schizophrenia and bipolar disorder patients currently expected to begin in 4Q 2019. BTI is a clinical-stage biopharmaceutical development company utilizing novel artificial intelligence approaches to identify and advance the next wave of medicines in neuroscience and immuno-oncology.

The first two cohorts in this double-blind, placebo-controlled, Phase 2 efficacy trial totaling 54 patients were completed expeditiously within three weeks of study initiation. Currently, the Company plans to enroll approximately 200 agitated schizophrenia patients. The primary endpoint of the study is change from baseline measured by the total score of Positive and Negative Symptom Scale - Excitatory Component scale1 (“PEC”). The secondary endpoints include assessment using the Agitation Calmness Evaluation Scale2 (“ACES”).

Vimal Mehta, Ph.D., Chief Executive Officer of BTI, stated, “We are pleased with the progress of our Phase 2 efficacy study with BXCL501 in agitated schizophrenia patients, a study we believe will support the launch of our pivotal Phase 3 studies in late 2019. We have now treated 96 subjects with BXCL501 to date, in addition to the positive data from our human Proof-of-Concept studies in multiple neuropsychiatric conditions with intravenous (“IV”) Dex. In parallel, we are accelerating clinical development plans for agitated dementia, opioid withdrawal symptoms and hyperactive delirium outside the currently on-going schizophrenia study. We continue to believe that agitation represents a multi-billion dollar burden to the healthcare system and is severely lacking effective and safe non-invasive treatment options.”

Robert Risinger, M.D., Vice President, Clinical Development of BTI, added, “We are delighted to be advancing the efficacy trial of our potent selective alpha-2 agonist, BXCL501. With successful completion of dosing in the first two patient cohorts, we are excited and looking forward to the results from this efficacy trial that are expected in 3Q 2019. Data from the Phase 1 pharmacokinetic (bioavailability) and safety study of BXCL501 exhibited clinically favorable features by achieving targeted exposure levels and the study met both its primary and secondary endpoints. We believe that results from our two BXCL501 clinical studies will lay a solid foundation to launch several Phase 3 pivotal trials across multiple neuro-psychiatric conditions with high unmet medical needs.”

1 PEC is a five-item scale that measures symptoms of agitation with each item rated from 1 (absent) to 7 (extreme).

2 ACES is a one-item scale that measures overall agitation and sedation ranging from 1 (marked agitation) to 9 (unarousable).

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 shown anti-agitation effects in multiple clinical studies across multiple neuropsychiatric indications. A Phase 1 pharmacokinetic (bioavailability) and safety study of BXCL501 yielded positive top-line data. It is initially being evaluated for the acute treatment of agitation resulting from schizophrenia in a Phase 2 efficacy trial. The Company plans to unveil future development plans for BXCL501 in agitated dementia, opioid withdrawal symptoms and hyperactive delirium through 2019.
