First patient randomized in SERENITY At-Home trial of BXCL501 for acute treatment of agitation associated with bipolar disorders or schizophrenia

Received FDA feedback on protocol for TRANQUILITY In-Care trial of BXCL501 for agitation associated with Alzheimer’s dementia (AAD)

Estimated 140 million annual acute agitation episodes associated with these conditions 1-3

NEW HAVEN, Conn., Nov. 12, 2024 (GLOBE NEWSWIRE) -- BioXcel Therapeutics, Inc. (Nasdaq: BTAI), a biopharmaceutical company utilizing artificial intelligence to develop transformative medicines in neuroscience, today announced the achievement of clinical and regulatory progress for its pivotal Phase 3 clinical trials of BXCL501 for the acute treatment of agitation associated with bipolar disorders or schizophrenia (SERENITY At-Home) and agitation associated with Alzheimer’s dementia (TRANQUILITY In-Care). There are no FDA-approved acute therapies for these conditions.

“We are pleased with the progress on our late-stage trials, which leverage our extensive clinical development experience,” said Vincent O’Neill, M.D., Chief of Product Development and Medical Officer of BioXcel Therapeutics. “With SERENITY At-Home, we are seeking to make BXCL501, which is currently approved under healthcare provider supervision as IGALMI™, available to millions of additional patients by potentially expanding its label for treating bipolar or schizophrenia-related agitation in the home. With TRANQUILITY In-Care, we have a unique opportunity in AAD, for which there is no U.S. regulatory precedent for episodic treatment. We look forward to continuing our development of BXCL501 for these critical unmet medical needs.”

SERENITY At-Home Pivotal Phase 3 trial

  • Designed to evaluate the safety of a 120 mcg dose of BXCL501 in the at-home setting for agitation associated with bipolar disorders or schizophrenia

    • The first patient has been randomized.

    • The Company announced trial initiation on September 5, 2024, with an expected trial duration of 9 to 12 months.

    • The double-blind, placebo-controlled, 12-week outpatient trial is expected to enroll approximately 200 patients residing at home.

TRANQUILITY In-Care Pivotal Phase 3 trial

  • Designed to evaluate the efficacy and safety of a 60 mcg dose of BXCL501 for AAD over a 12-week period

    • Received feedback from the U.S. Food and Drug Administration on proposed protocol

    • The double-blind, placebo-controlled study trial is expected to enroll a total of approximately 150 patients aged 55 years and older across the spectrum of Alzheimer’s disease severity with mild, moderate, and severe dementia with mini-mental state examination (MMSE) scores of 0 to 25 who reside in skilled nursing facilities, memory care units, or assisted living facilities.

    • The trial is expected to enroll patients with episodic agitation, with patients self-administering 60 mcg of BXCL501 or placebo when agitation episodes occur over the trial period.

    • The planned primary endpoint is a change from baseline in the Positive and Negative Syndrome Scale-Excitatory Component (PEC) total score at two hours post-first dose. This is the same endpoint used in previous TRANQUILITY trials and in studies that supported the FDA approval of IGALMI™ (dexmedetomidine) sublingual film.

    • Continued efficacy evaluations are expected to be conducted through performing additional PEC and complementary efficacy measures, including the global impression of change in agitation.
