Intra-Cellular Therapies Announces Positive Topline Results from Study 403 Evaluating Lumateperone as Monotherapy in Patients with Major Depressive Disorder with Mixed Features and Bipolar Depression with Mixed Features
Lumateperone 42mg was statistically significant on the primary endpoint of symptom reduction on the Montgomery Asberg Depression Rating Scale (MADRS) for each patient population including:
| • | combined major depressive disorder (MDD) with mixed features and bipolar depression with mixed features (5.7 point reduction v. placebo; p<0.0001; Cohen’s d effect size (ES) = 0.64) |
| • | MDD with mixed features (5.9 point reduction v. placebo; p<0.0001; ES= 0.67) |
| • | bipolar depression with mixed features (5.7 point reduction v. placebo; p<0.0001; ES= 0.64) |
Lumateperone 42mg was statistically significant on the key secondary endpoint of the clinician’s assessment of improvement in the overall severity on the Global Impression of Severity Scale (CGI-S) for each patient population including:
| • | combined MDD with mixed features and bipolar depression with mixed features (p<0.0001; ES= 0.59) |
| • | MDD with mixed features (p=0.0003; ES= 0.57) |
| • | bipolar depression with mixed features (p<0.0001; ES= 0.61) |
Favorable safety and tolerability profile observed, consistent with prior lumateperone trials
Conference call scheduled today at 8:30 a.m. ET
NEW YORK, March 28, 2022 (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 positive topline results from Study 403 evaluating lumateperone 42mg as monotherapy in the treatment of major depressive episodes in patients with major depressive disorder with mixed features and in patients with bipolar depression with mixed features.
Lumateperone 42mg given once daily met the primary endpoint in the study by demonstrating a statistically significant and clinically meaningful reduction in the MADRS total score compared to placebo at Week 6, as follows:

Lumateperone 42mg also met the key secondary endpoint in the study by demonstrating a statistically significant and clinically meaningful reduction in the CGI-S score compared to placebo at Week 6 in the combined patient population of MDD with mixed features and bipolar depression with mixed features (p<0.0001; ES= 0.59), patients with MDD with mixed features (p=0.0003; ES= 0.57), and patients with bipolar depression with mixed features (p<0.0001; ES=0.61).
In this study, lumateperone was generally safe and
well tolerated, with a side effect profile consistent with prior lumateperone trials. The most commonly reported adverse events that were observed at a rate greater than or equal to 5% and at least twice the rate of placebo in the total population
were somnolence, dizziness, and nausea.
“We are very pleased with the results of this highly successful trial in these difficult to treat patient populations with mixed features in MDD and mixed features in bipolar depression,” said Dr. Sharon Mates, Chairman and CEO of Intra-Cellular Therapies. “This study provides proof of concept in these patient populations and further validates lumateperone’s broad potential in mood disorders. We look forward to discussing these results with the FDA and determining next steps for the program.”
“In this study, lumateperone demonstrated a robust effect in both patients with MDD with mixed features and patients with bipolar depression with mixed features. This is particularly significant considering these patients suffer from greater symptom severity, increased recurrence of mood episodes, higher comorbidity and increased risk of suicide,” said Stephen Stahl MD, PhD, DSc (Hon.), Adjunct Professor, Department of Psychiatry, University of California, San Diego School of Medicine, La Jolla, California and Clinical Professor of Psychiatry and Neuroscience, University of California Riverside. “Given the lack of available therapies for these patient populations, there is a tremendous need for treatment options.”
About Study 403
Study 403 was a randomized, double-blind, placebo-controlled, global study to evaluate the efficacy and safety of lumateperone as monotherapy treatment for patients with major depressive episodes associated with MDD or Bipolar I or Bipolar II Disorder who also met the Diagnostic and Statistical Manual of Mental Disorder, 5th Edition (DSM-5) criteria for mixed-features. Additionally, patients were required to have a MADRS total score of ≥24, CGI-S of ≥4, and a Young Mania Rating scale (YMRS) score between 4 and 16.
Patients were randomized 1:1 to lumateperone 42mg (N=192) or placebo (N=191) with similar distribution between the two conditions. The primary endpoint of the study was the change from baseline versus placebo on the MADRS total score at Week 6 and the key secondary endpoint was the CGI-S which assessed the global severity of illness.
As initially designed, Study 403 evaluated lumateperone as a monotherapy treatment for patients with bipolar depression. Following the successful completion of our bipolar depression monotherapy and adjunctive program, Study 403 was amended to evaluate lumateperone as a treatment for patients with MDD with mixed features and bipolar depression with mixed features. The results presented above with respect to mixed features exclude the patients initially enrolled in Study 403 with bipolar depression. While these patients were diagnostically confirmed for bipolar depression, they were not diagnostically confirmed for bipolar depression with mixed features. A sensitivity analysis was conducted for the total population (ITT N=477) including these initially enrolled patients and the patients with bipolar depression with mixed features and patients with MDD with mixed features. In this pre-specified sensitivity analysis, lumateperone 42mg was statistically significant on the MADRS total score (5.6 point reduction v. placebo; p<0.0001; ES= 0.62) and CGI-S (p<0.0001; ES= 0.61).
In this study, lumateperone was generally safe and well tolerated in all patients who received at least one dose of drug, with a side effect profile consistent with prior lumateperone trials. Adverse events were mostly mild to moderate and similar to those seen in prior lumateperone studies in bipolar depression and schizophrenia.
About Mixed Features in Bipolar Depression and Major Depressive Disorder
Bipolar disorders and major depressive disorder are highly prevalent serious mental illnesses.
Bipolar disorders affect approximately 11 million adults in the U.S. and bipolar depression is the most common clinical presentation of the disorder. Patients with bipolar disorder generally spend more time in the depressive phase compared to the manic phase.
MDD affects approximately 21 million adults in the U.S. each year.
During a current major depressive episode, about one-third of patients with either bipolar disorder or MDD present with mixed features. Mixed features is defined by a patient having co-occurring subthreshold manic symptoms during their depressive episode or a patient having co-occurring subthreshold depressive symptoms during their manic episode.
Depressed patients with the presence of mixed features have greater severity of illness, higher rates of suicidal ideation and suicide, higher recurrence rates, and higher comorbidities. These patients are more difficult to treat than patients exhibiting depressive episodes without mixed features. The inclusion of the mixed features specifier in DSM-5 underscores the recently recognized importance of this clinical presentation.

CAPLYTA® (lumateperone) is indicated in adults for the treatment of schizophrenia and depressive episodes associated with bipolar I or II disorder (bipolar depression) as monotherapy and as adjunctive therapy with lithium or valproate.
Important Safety Information
Boxed Warnings:
| • | 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. |
| • | Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adults in short-term studies. All antidepressant-treated patients should be closely monitored for clinical worsening, and for emergence of suicidal thoughts and behaviors. The safety and effectiveness of CAPLYTA have not been established in pediatric patients. |
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 with pre-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. |
| • | Potential for Cognitive and Motor Impairment. Patients should use caution when operating machinery or motor vehicles until they know how CAPLYTA affects them. |
| • | 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. Dose reduction is recommended for concomitant use with strong CYP3A4 inhibitors or moderate CYP3A4 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. Dose reduction is recommended for patients with moderate or severe hepatic impairment.
Adverse Reactions: The most common adverse reactions in clinical trials with CAPLYTA vs. placebo were somnolence/sedation, dizziness, nausea, and dry mouth.
CAPLYTA is available in 10.5 mg, 21 mg, and 42 mg capsules.

About CAPLYTA (lumateperone)
CAPLYTA 42 mg is an oral, once daily atypical antipsychotic approved in adults for the treatment of schizophrenia and depressive episodes associated with bipolar I or II disorder (bipolar depression) as monotherapy and as adjunctive therapy with lithium or valproate. While the mechanism of action of CAPLYTA is unknown, the efficacy of CAPLYTA could be mediated through a combination of antagonist activity at central serotonin 5-HT2A receptors and postsynaptic antagonist activity at central dopamine D2 receptors.
Lumateperone is being studied for the treatment of major depressive disorder, and other neuropsychiatric and neurological disorders. Lumateperone is not FDA-approved for these disorders.
