Intra-Cellular Therapies Announces Presentations at the 2024 Psych Congress and NEI Congress

Presentations include results from two pivotal studies (Studies 501 and 502) evaluating lumateperone as an adjunctive therapy to antidepressants for the treatment of major depressive disorder (MDD)

Results show robust efficacy and favorable safety and tolerability profile for CAPLYTA

BEDMINSTER, N.J., Nov. 07, 2024 (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 presentations about lumateperone including the results from Phase 3 adjunctive Major Depressive Disorder (MDD) Studies 501 and 502 at Psych Congress held October 29- November 2 in Boston and Neuroscience Education Institute (NEI) Congress being held November 7-10 in Colorado Springs.

Studies 501 and 502 demonstrated robust efficacy of lumateperone as an adjunctive therapy to antidepressants for the treatment of MDD. In the primary endpoint, the Montgomery–Åsberg Depression Rating Scale (MADRS) total score, lumateperone demonstrated a large separation versus placebo of 4.9 points in Study 501 and 4.5 points in Study 502 with robust effect sizes of 0.61 and 0.56 respectively. This efficacy was confirmed in both studies not only by the primary endpoint, the MADRS total score, but also by the strong results in the clinician rated Clinical Global Impression Scale for Severity of Illness (CGI-S) scale and the patient reported Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR) scale. CAPLYTA's efficacy results were complemented with a favorable metabolic, weight and movement disorder profile.

In the adjunctive MDD setting these data present a compelling clinical profile for lumateperone in the treatment of MDD. These results further support the Company's vision for CAPLYTA to become a leading option for patients and providers across mood disorders.

Presentations at Psych Congress and NEI Congress as follows:

Study 501: "Lumateperone as Adjunctive Therapy in Patients With Major Depressive Disorder: Results From a Randomized, Double-blind, Phase 3 Trial."

Study 502: "Adjunctive Lumateperone in Patients With Major Depressive Disorder: Results From an Additional Randomized, Double-Blind, Phase 3 Trial."

Study 403: "Lumateperone Treatment in Patients With Major Depressive Disorder With Mixed Features: Results From a Randomized Controlled Trial."

Additional Presentation at Psych Congress:

Study 403: "Lumateperone in the Treatment of Major Depressive Disorder and Bipolar Depression With Mixed Features: Efficacy Across Symptoms."

About Major Depressive Disorder



Major Depressive Disorder (MDD) is a common mood disorder in the U.S. affecting an estimated 21 million adults each year. Depressive disorders are the number two cause of years lived with disability in the world. Symptoms include sadness, hopelessness, helplessness, feelings of guilt, irritability, loss of interest in formerly pleasurable activities, cognitive impairment, disturbed sleep patterns, and suicide ideation or behavior. MDD can cause severe functional impairment, adversely affecting interpersonal relationships, and may impact quality of life. Approximately two-thirds of patients with depression fail to achieve remission with first-line treatment.

CAPLYTA® (lumateperone) is indicated in adults for the treatment of schizophrenia and for the treatment of 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. 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 the treatment of 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 psychiatric and neurological disorders. Lumateperone is not FDA-approved for these disorders.
