CAPLYTA® (lumateperone) Schizophrenia Safety and Tolerability Profile Published in the Journal, International Clinical Psychopharmacology

Pooled analysis of 3 randomized, double-blind, pacebo-cotrolled trials supports the safety and the distinct and favorable tolerability profile of lumateperone 42 mg

Mean change from baseline in metabolic parameters and prolactin were similar to or reduced in lumateperone 42 mg relative to placebo treated patients

Mean change in weight and rates of EPS-related TEAEs were similar for lumateperone 42 mg and placebo treated patients

NEW YORK, June 07, 2021 (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 the article, "Safety and tolerability of lumateperone: a pooled analysis of late-phase placebo-and active-controlled clinical trials” (Kane et al. 2021), was recently published online in International Clinical Psychopharmacology.

This pooled analysis of 3 randomized, double-blind, placebo-controlled trials was conducted to evaluate the safety and tolerability of lumateperone 42 mg. The pooled population comprised of 1,073 patients with an acute exacerbation of schizophrenia randomized to placebo (n=412), lumateperone 42 mg (n=406), or risperidone 4 mg (n=255). Risperidone was included for assay sensitivity and not included for a comparison between CAPLYTA and risperidone.

In this pooled analysis, lumateperone 42 mg had a safety profile similar to placebo. Treatment-emergent adverse events (TEAEs) were predominantly mild and mean changes in weight and metabolic parameters as well as motor adverse events were similar to placebo. Rates of discontinuation due to treatment emergent adverse events (TEAEs) with lumateperone 42 mg (0.5%) were similar to placebo (0.5%) and lower than risperidone (4.7%). The only TEAEs that occurred at a rate of ≥ 5% and twice placebo for lumateperone were somnolence/sedation and dry mouth.

Mean change from baseline in metabolic parameters and prolactin were similar to or reduced in lumateperone 42 mg relative to placebo treated patients and were smaller than risperidone. Mean change in weight and rates of EPS-related TEAEs were similar for lumateperone 42 mg and placebo treated patients and less than for risperidone treated patients. This pooled analysis highlights the distinct safety and favorable tolerability profile of lumateperone 42 mg.

"CAPLYTA is an important addition in the treatment armamentarium for adult patients with schizophrenia. The achievement of efficacy while maintaining a favorable safety and tolerability profile in weight change, metabolic side effects and motor disturbances represents a significant advance as these adverse events are commonly associated with poor treatment adherence," said Dr. John Kane, Chair of Psychiatry and Professor of Psychiatry and Molecular Medicine at the Donald and Barbara Zucker School of Medicine, Hofstra/Northwell, New York.

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 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.
  • Sleepiness and Trouble Concentrating. 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, 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 42mg/day is an oral, once daily atypical antipsychotic approved for the treatment of schizophrenia of adults. While the mechanism of action of CAPLYTA in the treatment of schizophrenia 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.
