BOSTON, August 5, 2020 – Karuna Therapeutics, Inc. (NASDAQ: KRTX), an innovative 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, today announced financial results for the second quarter of 2020 and provided a general business update.

“We’ve made tremendous progress in advancing our clinical development programs evaluating KarXT in neuropsychiatric disorders, including schizophrenia and dementia-related psychosis, where the standards of care are simply insufficient,” said Steve Paul, M.D., chief executive officer, president and chairman of Karuna Therapeutics. “We remain focused on initiating Phase 3 trials within our EMERGENT program following a successful End-of-Phase 2 meeting with the FDA in the second quarter. This important next step brings us closer to providing a new, unique and differentiated treatment option to patients with schizophrenia.”

Dr. Paul continued: “Our commitment to discover and develop more effective treatments for neuropsychiatric disorders is not only underscored by our clinical-stage programs, but also the expansion of our drug discovery efforts. These discovery efforts have enabled us to broaden our approach to CNS drug discovery and development with the goal of enhancing Karuna’s pipeline of novel drug candidates for treating a wide range of neuropsychiatric disorders.”

Pipeline Updates

KarXT, a proprietary oral modulator of muscarinic cholinergic receptors, is Karuna’s lead product candidate combining xanomeline, a novel muscarinic agonist, with trospium, a U.S. Food & Drug Administration (FDA) approved muscarinic antagonist that does not appreciably cross the blood-brain-barrier, to preferentially stimulate muscarinic receptors in the central nervous system (CNS). KarXT is currently being evaluated as a potential treatment for neuropsychiatric disorders, including schizophrenia and dementia-related psychosis.

• KarXT in schizophrenia: The Company previously announced a positive outcome of its End-of-Phase 2 meeting with the FDA for KarXT for the treatment of acute psychosis in patients with schizophrenia. The outcome of the meeting supports the progression of KarXT into Phase 3 development. The formal minutes from the meeting also confirmed that the completed Phase 2 trial, along with one successful Phase 3 efficacy and safety trial, and additional safety data to meet regulatory requirements, would be acceptable to support a New Drug Application (NDA) filing.

• The Company is on track to initiate the first Phase 3 trial within its EMERGENT program, the clinical program evaluating KarXT for the treatment of acute psychosis in adults with schizophrenia, by the end of 2020. The EMERGENT program includes the completed positive Phase 2 clinical trial (EMERGENT-1) and additional planned efficacy and safety trials to support an NDA filing, including:

• EMERGENT-2: A five-week inpatient trial evaluating the efficacy and safety of KarXT in adults with schizophrenia. The EMERGENT-2 trial design shares many characteristics with the completed EMERGENT-1 trial, including duration of treatment, primary endpoint and patient population. EMERGENT-2 is a 1:1 randomized, flexible-dose, double-blind, placebo-controlled trial enrolling approximately 250 adults in the U.S., and will evaluate the change in Positive and Negative Syndrome Scale (PANSS) total score at Week 5 of KarXT versus placebo as the primary outcome measure. EMERGENT-2 is expected to commence by the end of 2020.

• EMERGENT-3: A five-week inpatient trial evaluating the safety and efficacy of KarXT in adults with schizophrenia. This trial will share characteristics of the completed EMERGENT-1 trial and planned EMERGENT-2 trial, including duration of treatment, patient population and primary outcome measure. Details of the EMERGENT-3 trial will be finalized by the end of 2020, with initiation expected in the first half of 2021.

• EMERGENT-4: A 52-week, outpatient, open-label long-term safety and tolerability extension trial of EMERGENT-2 and EMERGENT-3.

• EMERGENT-5: A 52-week, outpatient, open-label long-term trial evaluating the safety of KarXT in adults with schizophrenia who have not been enrolled in the EMERGENT-2 or EMERGENT-3 trials. This trial is expected to commence the first half of 2021.

• The Company plans to initiate a Phase 2 trial evaluating KarXT as an adjunctive therapy with standard of care for the treatment of psychosis in patients with schizophrenia who remain symptomatic on existing therapies. The Company previously planned to initiate a Phase 1b trial assessing potential Drug-Drug Interactions with a selection of currently marketed antipsychotics in healthy volunteers, but based on multiple considerations, including the evaluation of existing preclinical and clinical data supporting the potential of KarXT to augment traditional antipsychotic drugs, the Company will move forward directly to initiate a Phase 2 trial. The trial will evaluate the efficacy and safety of KarXT when dosed in conjunction with background antipsychotic treatment and its potential to improve symptoms in patients who had not achieved an adequate response on their current antipsychotic treatment.

• Data evaluating KarXT as an adjunctive therapy is intended to support a supplemental NDA filing assuming the successful development of KarXT as a monotherapy for the treatment of adults with schizophrenia. The Company plans to initiate this trial following the initiation of the Phase 3 trials within the EMERGENT program.

• The use of KarXT for the treatment of negative and cognitive symptoms in patients with schizophrenia remains of interest. The Company will collect data on the potential benefit of KarXT on negative and cognitive symptoms of schizophrenia as part of the EMERGENT program and the Company’s adjunctive therapy trial. The Company continues to evaluate the timing of potential trial designs specifically directed towards the negative and cognitive symptoms of schizophrenia.

• KarXT in dementia-related psychosis: The multi-cohort, placebo-controlled, inpatient Phase 1b trial evaluating the safety and tolerability of KarXT in healthy elderly volunteers is ongoing. The trial is designed to demonstrate safety and tolerability of KarXT in healthy elderly volunteers with the goal of selecting the most appropriate dose and dose-titration schedule to carry forward into future studies in patients with dementia-related psychosis.

• Topline data from the Phase 1b trial is anticipated by the end of 2020. Due to the particular vulnerability of the elderly population to COVID-19, the Company continues to monitor the ongoing COVID-19 pandemic and may elect to pause recruitment in this trial out of an abundance of caution for the health and safety of the elderly volunteers.

• KarXT in pain: As previously announced, the Company will not move forward to develop KarXT in pain.

Business Updates

• The Company recently announced a drug discovery collaboration with PsychoGenics, a phenotypic drug discovery platform company, to identify potential novel drug candidates for the treatment of severe neuropsychiatric disorders. The multi-year drug discovery collaboration leverages behavioral and physiological phenotypic screening and machine learning to identify novel neuropsychiatric treatments. Under the terms of the agreement, Karuna will provide an upfront payment to PsychoGenics for access to its proprietary platforms. Both parties are eligible to receive payments upon reaching pre-specified development, regulatory and commercial milestones, as well as royalties on net sales, for products developed under the agreement.

• Recruitment of top talent remains a key organizational priority to meet corporate and product development objectives. The Company continues to grow its leadership team with the addition of new strategic hires across functional areas, including Clinical Operations, Regulatory and Commercial.

Second Quarter 2020 Financial Results

The Company reported a net loss of $17.0 million for the second quarter of 2020, as compared to $15.1 million for the prior year period. The increase in net loss for the period was due to higher research and development expenses related to preparation for the initiation of the Company’s Phase 3 clinical trials within its EMERGENT program but was partially offset by lower general and administrative stock compensation expense.

Research and development expenses were $10.8 million for the second quarter of 2020, as compared to $6.8 million for the prior year period. The increase in research and development expenses for the period was primarily driven by expenses related to the preparation for the initiation of the Company’s Phase 3 clinical trials within its EMERGENT program, including CRO start-up costs and clinical trial material manufacturing. In addition, the Company had additional expenses related to its Phase 1b trials in healthy elderly volunteers and experimentally induced pain, increased personnel-related costs due to the increase in employee headcount, as well as expenses associated with consulting fees and the Company’s discovery programs.

General and administrative expenses were $7.0 million for the second quarter of 2020, as compared to $8.3 million for the prior year period. The decrease in general and administrative expenses was primarily due to the acceleration of option awards as a result of the Company’s IPO and was partially offset by increased expenses related to increased employee headcount and higher costs related to the support of business operations as a publicly traded company.

The Company ended the quarter with $367.6 million in cash, cash equivalents, and short-term investments compared to $389.4 million as of December 31, 2019. The Company expects that its current cash, cash equivalents, and short-term investments as of June 30, 2020 will enable the Company to fund its operating expenses and capital expenditure requirements for at least the next three years. This includes multiple potential clinical and development milestones, including an NDA submission of KarXT for the treatment of acute psychosis in patients with schizophrenia, pending the outcomes of the Company’s planned clinical trials. Additional activities which may be funded include the completion of the Phase 1b and potential Phase 2 trial for the treatment of dementia-related psychosis and continued investment into pipeline expansion, including evaluating KarXT as an adjunctive therapy in patients with schizophrenia.
