INTRA-CELLULAR THERAPIES REPORTS FIRST QUARTER 2020 FINANCIAL RESULTS AND PROVIDES CORPORATE UPDATE

NEW YORK, May 7, 2020 /GLOBE NEWSWIRE/ — Intra-Cellular Therapies, Inc. (Nasdaq: ITCI), a biopharmaceutical company focused on the development and commercialization of therapeutics for central nervous system (CNS) disorders, today announced its financial results for the first quarter ended March 31, 2020, and provided a corporate update.

“In the midst of these unprecedented times we are proud of the agile adaptation of our organization to successfully execute a virtual launch of CAPLYTA, a new treatment option for adult patients suffering from schizophrenia,” said Dr. Sharon Mates, Chairman and CEO of Intra-Cellular Therapies. “Beyond our commercial efforts, we also continue to make progress in the advancement of our development programs, having completed patient enrollment in our Phase 3 clinical trial evaluating lumateperone as an adjunctive treatment in bipolar depression (Study 402) and clinical conduct in ourproof-of-mechanism (Phase I/II) study evaluatingITI-214 in patients with heart failure.”

CORPORATE UPDATE

COMMERCIAL HIGHLIGHTS

• Successful Launch of CAPLYTA

o Comprehensive promotional activities for CAPLYTA commenced the week of March 30, 2020, following U.S. Food and Drug Administration (FDA) approval of CAPLYTA for the treatment of schizophrenia in adults in December 2019. The efficacy of CAPLYTA 42 mg was demonstrated in two placebo-controlled trials, showing a statistically significant benefit over placebo on the primary endpoint, the Positive and Negative Syndrome Scale (PANSS) total score. In pooled data from short term studies, mean changes from baseline in weight, fasting glucose, triglycerides and total cholesterol were similar between CAPLYTA and placebo. The incidence of extrapyramidal symptoms was similar to placebo.

o Successful completion of a 100% virtual national launch meeting, after onboarding our neuroscience sales specialists that were hired in the first quarter of 2020. The vast majority of our specialists have prior psychiatry medication sales experience, including antipsychotics. After successful

completion of our virtual national launch meeting, our neuroscience sales specialists are now actively engaging healthcare providers with the goal of providing comprehensive education on CAPLYTA. Our sales specialists are equipped with remote product presentation and sampling capability. These activities are being complemented by virtualpeer-to peer medical education and expanded digital outreach programs.

o Substantial progress in our market access coverage determinations with payers and we are pleased with the coverage achieved to date.

o Introducing LYTAlink^™: In support of patient access and affordability we have also introduced LYTAlink^™, a comprehensive patient support program designed to provide a number of access and affordability offerings to eligible CAPLYTA patients. The program offerings consist of coverage and reimbursement services,out-of-pocket copay support for commercially insured patients, medication compliance communications, and patient assistance relief specifically for eligible patients without insurance.

o Manufacturing and supply chain related activities are in place and are supporting commercial demand for CAPLYTA. We have substantial product supply in the U.S. with long expiry dating to support expected demand.

CLINICAL HIGHLIGHTS

• Lumateperone in Bipolar Depression: We have completed patient enrollment in Study 402, our Phase 3 study evaluating lumateperone as adjunctive therapy in bipolar depression, and anticipate reporting topline results from this study inmid-2020.

• ITI-214 in Heart Failure: Clinical conduct in our Phase 1/2 clinical trial ofITI-214, our phosphodiesterase 1 (PDE1) inhibitor, in patients with chronic systolic heart failure has been completed. This study evaluates the hemodynamic profile and safety of single ascending doses ofITI-214. We anticipate reporting topline results from this trial in the second quarter of 2020.

• Other Clinical Programs: We are continuing necessary activities to advance our other development programs and to ensure patient safety in accordance with recent FDA guidelines for clinical trial conduct in theCOVID-19 pandemic environment. These programs include our lumateperone clinical program in major depressive disorder, our long-acting injectable program of lumateperone, ourITI-214 program in Parkinson’s disease and the initiation of early stage clinical studies forITI-333, our novel, oral modulator of mu opioid and serotonin receptors for the treatment of opioid and other substance use disorders, pain, and mood disorders. We will provide additional updates on our clinical programs as the current environment evolves.

Selected First Quarter 2020 Financial Results

The Company recorded net product sales of CAPLYTA for the first quarter of 2020 of approximately $882,500. No net product sales were reported for the comparable period of 2019.

The Company reported a net loss of $47.4 million, or $0.73 per share (basic and diluted), for the first quarter of 2020 compared to a net loss of $34.8 million, or $0.63 per share (basic and diluted), for the first quarter of 2019.

Research and development (R&D) expenses for the first quarter of 2020 were $16.0 million, compared to $25.0 million for the first quarter of 2019. The $9.0 million decrease is primarily due to lower clinical andnon-clinical related costs for lumateperone, manufacturing costs, and is partially offset by highernon-lumateperone related project costs and higher labor costs in the first quarter of 2020.

Selling, general and administrative (SG&A) expenses were $34.1 million for the first quarter of 2020, compared to $11.7 million for the same period in 2019. The increase of $22.4 million is due to an increase of $15.6 million for selling related costs and an increase of $6.8 million for general and administrative costs. The increase in selling related costs is due primarily to hiring a sales force, resulting in an increase in labor expenses of approximately $9.9 million and commercialization costs of $5.8 million. The increase in general and administrative costs is due primarily to an increase in professional fees of approximately $2.1 million, labor related expenses of $1.5 million, and information technology expenses of $1.5 million.

Cash, cash equivalents, restricted cash and investment securities totaled $450.4 million at March 31, 2020, compared to $224.0 million at December 31, 2019. In January 2020, the Company completed a $295.0 million public offering resulting in net proceeds to the Company of approximately $277.0 million from the sale of 10 million shares of its common stock, after deducting underwriting discounts and commissions and offering expenses paid by the Company.

CAPLYTA^™ (lumateperone) is indicated for the treatment of schizophrenia in adults. CAPLYTA is available in 42 mg capsules.

Important Safety Information

Boxed Warning: Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. CAPLYTA is not approved for the treatment of patients with dementia-related psychosis.

Contraindications: CAPLYTA is contraindicated in patients with known hypersensitivity to lumateperone or any components of CAPLYTA. Reactions have included pruritus, rash (e.g. allergic dermatitis, papular rash, and generalized rash), and urticaria.

Warnings & Precautions:Antipsychotic drugs have been reported to cause:

• Cerebrovascular Adverse Reactions in Elderly Patients with Dementia-Related Psychosis, including stroke and transient ischemic attack. See Boxed Warning above.

• Neuroleptic Malignant Syndrome (NMS), which is a potentially fatal reaction. Signs and symptoms include: high fever, stiff muscles, confusion, changes in breathing, heart rate, and blood pressure, elevated creatinine phosphokinase, myoglobinuria (and/or rhabdomyolysis), and acute renal failure. Patients who experience signs and symptoms of NMS should immediately contact their doctor or go to the emergency room.

• Tardive Dyskinesia, a syndrome of uncontrolled body movements in the face, tongue, or other body parts, which may increase with duration of treatment and total cumulative dose. TD may not go away, even if CAPLYTA is discontinued. It can also occur after CAPLYTA is discontinued.

• Metabolic Changes,including hyperglycemia, diabetes mellitus, dyslipidemia, and weight gain. Hyperglycemia, in some cases extreme and associated with ketoacidosis, hyperosmolar coma or death, has been reported in patients treated with antipsychotics. Measure weight and assess fasting plasma glucose and lipids when initiating CAPLYTA and monitor periodically during long-term treatment.

• Leukopenia, Neutropenia, and Agranulocytosis (including fatal cases).Complete blood counts should be performed in patients withpre-existing low white blood cell count (WBC) or history of leukopenia or neutropenia. CAPLYTA should be discontinued if clinically significant decline in WBC occurs in absence of other causative factors.

• Decreased Blood Pressure & Dizziness.Patients may feel lightheaded, dizzy or faint when they rise too quickly from a sitting or lying position (orthostatic hypotension). Heart rate and blood pressure should be monitored and patients should be warned with known cardiovascular or cerebrovascular disease. Orthostatic vital signs should be monitored in patients who are vulnerable to hypotension.

• Falls. CAPLYTA may cause sleepiness or dizziness and can slow thinking and motor skills, which may lead to falls and, consequently, fractures and other injuries. Patients should be assessed for risk when using CAPLYTA.

• Seizures.CAPLYTA should be used cautiously in patients with a history of seizures or with conditions that lower seizure threshold.

• Sleepiness and Trouble Concentrating.Patients should use caution when operating machinery or motor vehicles until they know how CAPLYTA affects them.

4

• Body Temperature Dysregulation. CAPLYTA should be used with caution in patients who may experience conditions that may increase core body temperature such as strenuous exercise, extreme heat, dehydration, or concomitant anticholinergics.

• Dysphagia. CAPLYTA should be used with caution in patients at risk for aspiration.

Drug Interactions:CAPLYTA should not be used with CYP3A4 inducers, moderate or strong CYP3A4 inhibitors and UGT inhibitors.

Special Populations:Newborn infants exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. Breastfeeding is not recommended.Use of CAPLYTA should be avoided in patients with moderate or severe liver problems.

Adverse Reactions: The most common adverse reactions in clinical trials with CAPLYTA vs. placebo were somnolence/sedation (24% vs. 10%) and dry mouth (6% vs. 2%).

About CAPLYTA (lumateperone)

CAPLYTA is an oral, once daily medicine approved for the treatment of schizophrenia of adults (42mg/day). The mechanism of action of CAPLYTA in the treatment of schizophrenia is unknown. However, the efficacy of CAPLYTA could be mediated through a combination of antagonist activity at central serotonin5-HT2A receptors and postsynaptic antagonist activity at central dopamine D2 receptors.

CAPLYTA is being developed for the treatment of bipolar depression, depression and other neuropsychiatric and neurological disorders. CAPLYTA has not been demonstrated to be safe and effective in these other areas.
