NEW YORK, Dec. 12, 2019 (GLOBE NEWSWIRE) -- Intra-Cellular Therapies, Inc. (ITCI), a biopharmaceutical company focused on the development of therapeutics for central nervous system (CNS) disorders, today announced data featured yesterday during the 58th Annual Meeting of the American College of Neuropsychopharmacology (ACNP) held in Orlando, FL, December 8-11, 2019 included:

  • “Lumateperone (ITI-007) in the Treatment of Bipolar Depression: Results from a Randomized Clinical Trial” (Poster W123)

This poster presented data from the positive Phase 3 clinical trial of lumateperone for the treatment of patients with bipolar depression (ITI-007-404 or Study ‘404). Study 404 was conducted globally, including in the U.S., and included 381 patients randomized (1:1) to receive lumateperone 42 mg or placebo once daily for six weeks. Lumateperone met its primary endpoint of change from baseline at Week 6 on the Montgomery-Åsberg Depression Rating Scale (MADRS) total score versus placebo (p<0.0001; effect size (ES) = 0.56). In the intent-to-treat study population, the LS mean improvement from baseline for lumateperone 42 mg was 16.7 points, versus 12.1 points for placebo, for a 4.6-point difference between the two groups. Lumateperone also met the study’s key secondary endpoint, Clinical Global Impression Scale for Bipolar for Severity of Illness (CGI-BP-S) Total Score (p<0.001; ES = 0.46). In addition, the CGI component that specifically assesses depression showed improvement with lumateperone versus placebo (CGI-BP-S Depression Score; p<0.001; ES = 0.50). This improvement was statistically significant as early as week 1, the first time point measured, and was maintained at every time point throughout the study.

In subgroup analyses of both Bipolar I patients and Bipolar II patients, statistically significant improvements were seen versus placebo on the MADRS total score (Bipolar I patients: p<.0001; ES: 0.49; and Bipolar II patients: p<.001; ES: 0.81).

These results were supported by statistically significant improvements on responder rates and remission rates, demonstrating the clinical meaningfulness of the primary outcome, with 51.1% of patients on lumateperone meeting MADRS response criteria (50% improvement from baseline) versus 36.7% for placebo at Day 43 (p<0.001). Additionally, 39.9% of patients on lumateperone were considered remitters (MADRS ≤12) versus 33.5% for placebo (p=<0.05).

The safety profile in this study was consistent with previously reported placebo-controlled and open-label studies in patients with schizophrenia. Lumateperone showed similar effects as placebo on assessments of body weight, metabolic parameters, extrapyramidal symptoms, and prolactin. Rates of akathisia, restlessness and extrapyramidal symptoms combined were less than 1% and similar to placebo. The most commonly reported adverse events that were observed at a rate greater than 5% and higher than placebo were somnolence (8.5%) and nausea (6.4%). The rates of discontinuation due to treatment emergent adverse events for lumateperone were less than 5 percent.

“The results of this trial including lumateperone’s separation from placebo on multiple measures of depression accompanied by its metabolic and motor profile are impressive,” said Joseph Calabrese, MD, Director, Mood Disorders Program, Department of Psychiatry, University Hospitals Cleveland Medical Center. “Lumateperone represents a potential important option for the treatment of patients suffering from Bipolar I and Bipolar II disorder who are experiencing depressive episodes. These are highly prevalent and difficult to treat conditions for which there is a need for effective and better tolerated options.”

  • “Efficacy and Safety of Lumateperone 42 mg in the Treatment of Schizophrenia: A Pooled Analysis of Randomized Clinical Trials” (Poster W201)

This poster highlighted the clinical results of lumateperone 42 mg, including its safety and tolerability profile from the short-term controlled studies of lumateperone in the treatment of patients with acute exacerbations of schizophrenia. The poster included additional post-hoc pooled analyses that found lower rates of MetSy in patients treated with lumateperone than in patients treated with risperidone.

In these double-blind, placebo-controlled studies of 4 to 6 weeks duration, patients were randomized to either lumateperone 42mg (n=406), risperidone 4mg (n=255) or placebo (n=412). The percentage of patients meeting criteria for MetSy at baseline was similar across groups (18.2% for lumateperone, 19.2% for risperidone and 17.0% for placebo).

At study endpoint, fewer patients on lumateperone met the MetSy criteria compared with the percentage on risperidone (15.0% v. 24.7%). Among those patients with MetSy at baseline, the percentage who no longer met criteria for MetSy after study treatment was nearly twice as high among patients treated with lumateperone as among patients treated with risperidone (45.9% v. 24.5%). Among patients without MetSy at baseline, the percentage that developed MetSy during study treatment with lumateperone was half that in risperidone-treated patients (6.3% v. 12.6%).

“Metabolic Syndrome is a highly prevalent set of risk factors among patients with schizophrenia and is associated with many commonly prescribed antipsychotics,” said Dr. Christoph Correll, Professor of Psychiatry and Molecular Medicine at the Zucker School of Medicine at Hofstra/Northwell, New York. “Previous data have indicated that lumateperone is associated with effects similar to placebo in short-term trials on body weight and cardiometabolic parameters, including levels of blood glucose, insulin, and cholesterol. Moreover, in a switch safety study, lumateperone was associated with improvements in several important cardiometabolic parameters. These new safety analyses in the broader context of a well-recognized clinical entity, the Metabolic Syndrome, which is a well-established marker for overall cardiovascular risk, are encouraging.”

  • Additional Results from a 12-Month Open-Label Safety Study of Lumateperone (ITI-007) in Patients with Stable Symptoms of Schizophrenia” (Poster W203).

Additional results from the lumateperone long-term safety study were presented. The data presented showed the safety of long-term lumateperone treatment was consistent with previously reported studies and associated with a low risk of metabolic, EPS, and prolactin side effects. Patients with stable schizophrenia symptoms continued to show improvement in PANSS scores with lumateperone treatment throughout the 1-year open-label study. Furthermore, in patients with schizophrenia and comorbid depression symptoms at baseline lumateperone 42 mg improved depressive symptoms.

About Lumateperone Bipolar Depression Program

The lumateperone clinical trial program in bipolar depression includes three Phase 3 trials. Two trials, Study 401 and Study 404, evaluated lumateperone as monotherapy and the third trial, Study 402, is evaluating lumateperone as an adjunctive therapy to lithium or valproate. The safety and efficacy of lumateperone in bipolar disorder has not been established.

About Metabolic Syndrome (MetSy)

According to the National Heart, Lung, and Blood Institute, MetSy is defined as the presence of at least 3 of the following 5 risk factors: abdominal obesity as measured by waist circumference; elevated triglyceride levels; low HDL cholesterol levels; high blood pressure; and elevated fasting blood sugar. People who meet this definition have 5-6 times the risk of developing type 2 diabetes and a 3-6 times increased risk of mortality due to coronary heart disease than people who do not1. People with severe mental illness have significantly higher rates of the MetSy than the general population2 and are likely to die 12-15 years earlier, with cardiovascular disease as the primary driver for this early mortality3. A major factor in the development of MetSy among people with severe mental illness is the use of antipsychotic medication4.

About Lumateperone

Lumateperone is an investigational molecule that provides selective and simultaneous modulation of serotonin, dopamine, and glutamate - three neurotransmitter pathways implicated in severe mental illness. Lumateperone is a potent serotonin 5-HT2A receptor antagonist, a dopamine receptor phosphoprotein modulator (DPPM) acting as a presynaptic partial agonist and postsynaptic antagonist at dopamine D2 receptors, a dopamine D1 receptor-dependent indirect modulator of glutamate (both NDMA and AMPA), and a serotonin reuptake inhibitor. Lumateperone in an investigational new drug under review with the FDA for the treatment of schizophrenia, its safety and efficacy has not been established, and it has not been approved for marketing for any use by the U.S. Food and Drug Administration (FDA) or any other regulatory authority in any other jurisdiction.
