FDA concludes site inspection is closed under 21 C.F.R.20.64(d)(3); Voluntary Action Indicated
Company believes this further supports reliability of data from TRANQUILITY II trial of BXCL501
NEW HAVEN, Conn., March 03, 2025 — BioXcel Therapeutics, Inc. (NASDAQ: BTAI), a biopharmaceutical company utilizing artificial intelligence to develop transformative medicines in neuroscience, today announced that the U.S. Food and Drug Administration (FDA) has concluded that the inspection of a single site in its TRANQUILITY II Phase 3 trial is closed under 21 C.F.R.20.64(d)(3) and released the Establishment Inspection Report. The FDA has designated “Voluntary Action Indicated” for the site.
“We believe this report and the closing of the investigation, together with the positive findings from the independent audit we announced in October 2023, further reaffirm the data integrity from the single site and the body of clinical evidence we intend to include in a potential sNDA submission,” said Vimal Mehta, Ph.D., CEO of BioXcel Therapeutics. “We have already received FDA feedback on the protocol for our TRANQUILITY In-Care Phase 3 trial and look forward to advancing this program with our lead neuroscience asset BXCL501.”
About BXCL501
Outside of its approved indication by the U.S. Food and Drug Administration as IGALMI® (dexmedetomidine) sublingual film, BXCL501 is an investigational proprietary, orally dissolving film formulation of dexmedetomidine, a selective alpha-2 adrenergic receptor agonist. BXCL501 is under investigation by BioXcel Therapeutics for the acute treatment of agitation associated with Alzheimer’s dementia and for the acute treatment of agitation associated with bipolar I or II disorder or schizophrenia in the at-home setting. The safety and efficacy of BXCL501 for these investigational uses have not been established. BXCL501 has been granted Breakthrough Therapy designation by the FDA for the acute treatment of agitation associated with dementia and Fast Track designation for the acute treatment of agitation associated with schizophrenia, bipolar disorders, and dementia.
About the TRANQUILITY In-Care Phase 3 Trial
The TRANQUILITY In-Care trial is designed as a double-blind, placebo-controlled study to evaluate the efficacy and safety of a 60 mcg dose of BXCL501 over a 12-week period for agitation associated with Alzheimer’s dementia in the care setting. The trial is expected to enroll approximately 150 patients 55 years and older who have mild, moderate, or severe dementia with mini-mental state examination scores of 0 to 25 and who reside in skilled nursing facilities, memory care units, or assisted living facilities. Patients will self-administer 60 mcg of BXCL501 or placebo when episodic agitation episodes occur over the trial period. The primary endpoint is expected to be a change from baseline in the Positive and Negative Syndrome Scale-Excitatory Component (PEC) total score at two hours post-first dose. Additional PEC and Clinical Global Impressions – Improvement Scale measurements will also be obtained during the trial.
