Intra-Cellular Therapies to Host Conference Call to Provide Regulatory Update Following Recent Meeting with FDA

Conference call scheduled today at 8:30 am ET

NEW YORK, August 5, 2019 (GLOBE NEWSWIRE) — Intra-Cellular Therapies, Inc. (Nasdaq:ITCI), a biopharmaceutical company focused on the development of therapeutics for central nervous system (CNS) disorders, today announced that it recently met with the U.S. Food and Drug Administration (FDA) and reached agreement to submit additional non-clinical information in connection with the FDA’s ongoing review of the Company’s New Drug application (NDA) for lumateperone for the treatment of schizophrenia. The FDA has informed the Company that the planned submission of this additional information constitutes a major amendment to the NDA, resulting in a three-month extension of the Prescription Drug User Fee Act (PDUFA) goal date to December 27, 2019 in order to provide time for a full review of the submission.

“We are pleased with the productive dialogue we have had with the FDA,” said Dr. Sharon Mates, Chairman and CEO of Intra-Cellular Therapies. “We intend to provide the FDA with the requested information in the coming weeks and we believe this information will be sufficient to address the FDA’s requests.”

The Company has agreed with the FDA to provide additional information related to toxicology findings in previous animal studies with the objective to further substantiate the Company’s position that those findings are not relevant to humans due to species specific differences in the metabolism of lumateperone. The Company is performing a limited number of in-vitro analyses, including the analysis of animal and human plasma samples from previous studies to confirm that the metabolic pathway, and the metabolites formed, are different in animals and humans. The Company has commenced the requested analyses and expects to complete them shortly and provide the information to the FDA.

About Lumateperone

Lumateperone, our lead product candidate, is a 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 is an investigational new drug and has not been approved for marketing for any use by the FDA or any other regulatory authority in any other jurisdiction.

About Intra-Cellular Therapies

Intra-Cellular Therapies is developing novel drugs for the treatment of neuropsychiatric and neurodegenerative diseases and diseases of the elderly, including Parkinson’s and Alzheimer’s disease. The Company is developing its lead drug candidate, lumateperone (also known as ITI-007), for the treatment of schizophrenia, bipolar disorder, behavioral disturbances in patients with dementia, including Alzheimer’s disease, depression and other neuropsychiatric and neurological disorders. Lumateperone is under review by the FDA for the treatment of schizophrenia and is in Phase 3 clinical development for the treatment of bipolar depression. Intra-Cellular Therapies is also utilizing its phosphodiesterase (PDE) platform and other proprietary chemistry platforms to develop drugs for the treatment of CNS and other disorders. The lead molecule in the Company’s PDE1 portfolio, ITI-214, is in development for the treatment of symptoms associated with Parkinson’s disease and for the treatment of heart failure.
