186 Results From a 12-Month Open-label Safety Study of Lumateperone (ITI-007) in Patients with Stable Symptoms of Schizophrenia
Notice bibliographique
Résumé
Abstract: Introduction: Lumateperone (lumateperone tosylate, ITI-007) is an investigational drug for the treatment of schizophrenia, bipolar depression, and other disorders. Lumateperone has a unique mechanism of action that simultaneously modulates serotonin, dopamine, and glutamate neurotransmission. This may provide advantages in the treatment of the broad symptoms associated with schizophrenia, including negative and depression symptoms. In 2 previous placebo-controlled trials in patients with acute schizophrenia, lumateperone 42mg (ITI-007 60mg) demonstrated statistically significant improvement in the Positive and Negative Syndrome Scale (PANSS) Total score compared with placebo. In these studies, lumateperone was well tolerated with a safety profile similar to placebo. This open-label long-term study evaluated the safety and effectiveness of lumateperone 42mg in patients with schizophrenia and stable symptoms. Methods: Patients with stable schizophrenia were treated for up to 1 year with lumateperone 42mg. Safety assessments included adverse events (AEs), body weight, laboratory parameters, and extrapyramidal symptoms (EPS)/motor symptom assessments. Efficacy analyses included evaluation of changes in PANSS Total score and in depression symptoms, as measured by the Calgary Depression Scale for Schizophrenia (CDSS). Results: In the 1-year open-label study, 602 patients received at least 1 dose of lumateperone 42mg; at the time of this interim analysis, 107 patients had completed 1 year of treatment. Only 4 TEAEs occurred in ≥5% of patients (weight decrease, dry mouth, headache and diarrhea); the majority of AEs were mild or moderate in intensity. Most metabolic parameters and mean prolactin levels decreased from SOC baseline, as did mean body weight and BMI. Based on AE reporting and EPS/motor symptom scales, lumateperone treatment was associated with minimal EPS risk. Lumateperone 42mg treatment was associated with significant reductions in PANSS Total score from baseline, with continuing PANSS improvement throughout the study. In patients with moderate-to-severe depression symptoms at baseline (CDSS>5), mean CDSS scores decreased from 7.4 (baseline) to 3.1 (Day 300); 60% of patients met CDSS response criteria (50% improvement from baseline) by Day 75 and this response rate was maintained through day 300. Similar magnitude of CDSS improvement was seen regardless of concurrent antidepressant therapy. Conclusion: In long-term treatment, lumateperone was associated with minimal metabolic, EPS, and cardiovascular safety issues relative to current SOC antipsychotic therapy. Lumateperone improved schizophrenia symptoms with continued long-term treatment. In patients with moderate-to-severe depression symptoms at baseline, lumateperone treatment was associated with marked improvement in CDSS scores. These data are consistent with and extend data previously reported in placebo-controlled studies in patients with acute schizophrenia treated with lumateperone.
