Optimal exposure levels for developing BXCL501 sublingual thin film identified
Results support clinical evaluation of dexmedetomidine in acute treatment of agitation resulting from neuropsychiatric disorders and dementia
BRANFORD, Conn., June 27, 2018 (GLOBE NEWSWIRE) -- BioXcel Therapeutics, Inc. (“BTI”) (Nasdaq:BTAI), a clinical stage biopharmaceutical development company utilizing novel artificial intelligence to identify the next wave of medicines across neuroscience and immuno-oncology, today announced positive data from its Phase 1b study evaluating intravenous (IV) administration of dexmedetomidine (Dex). Data from this study will aid in establishing the optimal dose for BXCL501, a sublingual formulation of Dex, for the acute treatment of agitation.
Sheldon Preskorn, MD, a leading Psychiatric Drug Development Expert and BTI’s Neuroscience Clinical Advisor, commented, “The development of a medication that treats agitation without the various safety concerns of existing options is a large unmet medical need – a topic addressed at a symposium1 conducted on June 14th in New York City by the New York Academy of Sciences. The current Phase 1b study was designed to evaluate the safety and establish an optimal exposure range. This information will be used to determine the ideal dosing strategy for the continued clinical development of BXCL501.”
BTI completed the first part of its Phase 1b, randomized, placebo-controlled, dose ranging, single-center study of the IV formation of Dex in healthy middle-aged and elderly participants. The study enrolled 16 healthy volunteers aged 55-75. The primary endpoint of the study was the dose and drug exposure levels required to produce mild sedation, which can serve as a surrogate endpoint for treating agitation using the Richmond Agitation- Sedation Scale (RASS)2 score. The goal of the study was to achieve mild sedation without any clinically meaningful cardiovascular side effects. In this study:
“Treatment of agitation remains a significant global healthcare challenge in patients with various neuropsychiatric disorders and dementia, as the currently available treatment options are suboptimal, invasive, difficult to administer and often pose safety issues especially in the elderly. The positive data from this Phase 1b study of the IV formulation of Dex represents an important step forward in the clinical development of BXCL501," said Dr. Vincent J. O’Neill, Chief Medical Officer of BTI. “These results clearly demonstrate doses and exposure levels of the IV formulation of Dex that have calming effects in healthy subjects without clinically meaningful changes in blood pressure or heart rate. With these findings in hand, we plan to evaluate the selected dose and exposure levels identified in this ongoing Phase 1b study in patients with senile dementia of the Alzheimer type (SDAT).”
