Karuna Therapeutics to Present Additional Data from the Phase 2 Clinical Trial of KarXT for the Treatment of Psychosis in Patients with Schizophrenia at the American Society of Clinical Psychopharmacology 2020 Annual Meeting

Karuna Therapeutics, Inc. (NASDAQ: KRTX), a clinical-stage biopharmaceutical company committed to developing novel therapies with the potential to transform the lives of people with disabling and potentially fatal neuropsychiatric disorders and pain, announced today that data from the Phase 2 clinical trial evaluating KarXT for the treatment of acute psychosis in patients with schizophrenia will be presented at the American Society of Clinical Psychopharmacology (ASCP) 2020 Annual Meeting, to be held virtually from May 29 to May 30, 2020. The poster and oral presentation will include new and previously reported efficacy and safety data from the Phase 2 clinical trial.

"We look forward to presenting efficacy and safety findings from our Phase 2 study evaluating KarXT as a potential treatment option for schizophrenia, including additional new safety data on the relative rates compared to placebo and time-course of treatment emergent adverse events," stated Steve Paul, M.D., chief executive officer of Karuna Therapeutics. "These additional findings further support the potential impact of addressing schizophrenia with a new mechanism of action that has the potential to effectively treat the condition and lessen the debilitating side effects associated with the current standard of care."

The accepted abstract listed below is available online on the ASCP meeting website at https://ascp.societyconference.com. All oral and poster presentations will be available for registered meeting attendees during the conference.

About KarXT

KarXT, a proprietary oral modulator of muscarinic cholinergic receptors, is Karuna’s lead product candidate that combines xanomeline, a novel muscarinic agonist, with trospium, an FDA-approved muscarinic antagonist that does not appreciably cross the blood-brain-barrier, to preferentially stimulate muscarinic receptors in the central nervous system (CNS). This novel product candidate, if approved, has the potential to usher in a new treatment paradigm and dramatically impact patients with schizophrenia and other psychotic disorders by providing a differentiated mechanism of action relative to current D2 dopamine and serotonin receptor-targeting antipsychotic drugs.

About Schizophrenia

Schizophrenia is a chronic, disabling disorder typically diagnosed in late teenage years or early adulthood. Characterized by recurring episodes of psychosis requiring long-term treatment with antipsychotic drugs in most patients, it affects more than 21 million people worldwide and 2.7 million Americans (0.5% - 1.0% of U.S. population).

At least one-third of patients with schizophrenia fail to respond to current treatments, with 74% of patients discontinuing within 18 months of initiation. People with schizophrenia have a 10- to 15-year reduction in life expectancy and struggle to maintain meaningful interpersonal relationships. The World Health Organization ranks psychosis as the third-most disabling medical condition in the world.

About Karuna

Karuna is an innovative clinical-stage biopharmaceutical company primarily focused on developing novel therapies to address disabling neuropsychiatric conditions characterized by significant unmet medical need. Karuna is currently conducting a Phase 2 clinical trial of its lead product candidate, KarXT (Karuna-Xanomeline-Trospium), for the treatment of acute psychosis in patients with schizophrenia. Karuna also plans to initiate clinical trials of KarXT to evaluate its potential therapeutic benefit in other central nervous system disorders, including psychosis in Alzheimer’s disease, as well as pain.
