Karuna Therapeutics Announces Results from Phase 1b Trial Evaluating the

Safety and Tolerability of KarXT in Healthy Elderly Volunteers

Company to initiate a Phase 2 trial evaluating KarXT in dementia-related psychosis in the first

half of 2022

Results suggest that KarXT can be administered to elderly volunteers at doses which achieve

xanomeline blood levels similar to those reported in the Phase 2 EMERGENT-1 trial in adults

with schizophrenia while maintaining a favorable tolerability profile

The majority of healthy elderly volunteers in the Phase 1b trial were titrated to xanomeline

doses of 150 to 200 mg when dosed with KarXT

Safety and tolerability profile in Phase 1b trial in healthy elderly volunteers consistent with prior

trials of KarXT

BOSTON—June 23, 2021— Karuna Therapeutics, Inc. (NASDAQ: KRTX), a clinical-stage biopharmaceutical company driven to create and deliver transformative medicines for people living with psychiatric and neurological conditions, today announced data from its completed Phase 1b trial evaluating the safety and tolerability of KarXT (xanomeline-trospium) in healthy elderly volunteers. The Company had previously announced a preliminary analysis of data from the first two cohorts in the trial earlier this year. Based on results from the Phase 1b trial in healthy elderly volunteers, the Company plans to initiate a Phase 2 trial evaluating KarXT in dementia-related psychosis in the first half of 2022.

The placebo-controlled, inpatient Phase 1b dose-ranging trial consisted of three cohorts, each enrolling 16 healthy elderly volunteers, randomized 3:1 to receive KarXT or placebo. As part of the flexible dosing protocol, a volunteer’s dose was increased if they were tolerating KarXT well at the time of the potential dose increase, as determined by a clinician. In the trial, the majority of healthy elderly volunteers were titrated to xanomeline doses of 150 to 200 mg when dosed with KarXT three times per day. As previously reported, pharmacokinetic data from Cohorts 1 and 2 demonstrated that healthy elderly volunteers achieved mean xanomeline blood levels comparable to, or slightly higher than, the mean xanomeline blood levels reported in the Phase 2 EMERGENT-1 trial evaluating KarXT in adults with schizophrenia. The Company plans to evaluate pharmacokinetic data from Cohort 3, once available. Previous trials of KarXT have demonstrated that the current formulation of KarXT results in xanomeline exposures, or blood levels, that are approximately 10% greater than blood levels seen in earlier trials of xanomeline alone.

The treatment-related adverse events (AEs) were similar to those observed in prior trials of KarXT, and a majority (>80%) were rated mild in severity. One serious AE of urinary retention was reported in Cohort 1. The Company believes the report of urinary retention was related to a higher dose of trospium used in Cohort 1 compared to doses used in Cohorts 2 and 3, where urinary retention was not observed. No serious or severe AEs were observed in Cohorts 2 and 3. Consistent with prior trials of KarXT, blood pressure in healthy elderly volunteers receiving KarXT was similar to placebo, and no syncopal events were observed. Heart rate increases observed in the trial were also consistent with prior trials of KarXT.

Data from the Phase 1b trial suggest that a lower dose ratio of trospium to xanomeline, compared to the ratios used in Phase 1 trials in healthy adult volunteers and in the Phase 2 EMERGENT-1 trial evaluating KarXT in adults with schizophrenia, was better tolerated by healthy elderly volunteers.

“We are encouraged that the data from our Phase 1b healthy elderly volunteers trial suggest that potentially therapeutic doses of KarXT can be administered to elderly adults while maintaining a favorable tolerability profile,” said Stephen Brannan, M.D., chief medical officer of Karuna Therapeutics. “Results from the third cohort provide additional data as we finalize the dosing and titration protocol for our Phase 2 trial in dementia-related psychosis.”

“The results from the Phase 1b trial in healthy elderly volunteers, as well as a prior Phase 2 study demonstrating the potential of xanomeline to treat and prevent psychosis in patients with Alzheimer’s disease, give us confidence in the potential utility of KarXT for the treatment of dementia-related psychosis,” added Steve Paul, M.D., chief executive officer, president and chairman of the board of Karuna Therapeutics. “These results support the progression of KarXT into a Phase 2 clinical trial for the treatment of dementia-related psychosis, which we plan to commence in the first half of 2022.”

About KarXT

KarXT, a proprietary oral modulator of muscarinic cholinergic receptors, is Karuna’s lead product candidate. It 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. 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 Karuna

Karuna Therapeutics is a clinical-stage biopharmaceutical company driven to create and deliver transformative medicines for people living with psychiatric and neurological conditions. At Karuna, we understand there is a need for differentiated and more effective treatments that can help patients navigate the challenges presented by these severe and disabling disorders. Utilizing our extensive knowledge of neuroscience, we are harnessing the untapped potential of the brain in pursuit of novel pathways to develop medicines that make meaningful differences in peoples’ lives.
