NEW YORK, March 31, 2015 (GLOBE NEWSWIRE) -- Intra-Cellular Therapies, Inc. (Nasdaq:ITCI), a biopharmaceutical company focused on the development of therapeutics for central nervous system (CNS) disorders, presented data regarding the ITI-007 development program and described the rationale supporting the strategy for the advancement of ITI-007 in multiple clinical indications at the 15th International Congress on Schizophrenia Research (ICOSR) in Colorado Springs.
In a poster the Company described the rationale for dose selection in the ongoing Phase 3 clinical trial in schizophrenia. Preclinical data predicted antipsychotic efficacy at human equivalent doses as low as 20 – 40 mg of ITI-007. Positron emission tomography (PET) data in healthy volunteers demonstrated striatal D2 receptor occupancy of ~20% and ~40% at doses of 20 mg and 40 mg, respectively. Striatal D2 receptor occupancy at 60 mg was projected to be approximately 50%. In a Phase 2 clinical trial in patients with schizophrenia, ITI-007 at a dose of 60 mg demonstrated a statistically significant and clinically meaningful improvement in psychosis with a favorable metabolic, cardiovascular and motor adverse event profile.
Based on the preclinical and clinical results described above the Company selected doses of 60 mg and 40 mg of ITI-007 for the ongoing Phase 3 clinical trial in schizophrenia. This study, ITI-007-301, is a randomized, double-blind, placebo-controlled, inpatient clinical trial in patients with an acutely exacerbated episode of schizophrenia. In this trial, over 400 patients are expected to be randomized to receive one of three treatments: 60 mg ITI-007, 40 mg ITI-007 or placebo in a 1:1:1 ratio. The Company anticipates topline results from this trial will be available in the second half of 2015.
In an oral presentation the Company summarized the clinical progress of ITI-007 to date and emphasized its rationale supporting the development of ITI-007 for other indications. ITI-007 has a unique pharmacological profile acting as a serotonergic, dopaminergic, and glutamatergic modulator. In addition, ITI-007 has a dose-dependent pharmacology. At low doses, ITI-007 acts mainly as a potent 5-HT2A receptor antagonist, with modest interaction with other drug targets. As the dose is increased, additional pharmacological interactions play a greater role, i.e., dopamine and glutamate receptor modulation and inhibition of SERT are gradually increased. The Company emphasized the pharmacological, pharmacodynamic and safety profile of ITI-007, which supports its development in other indications beyond schizophrenia, including bipolar disorder and major depressive disorder as well as behavioral disturbances in patients with dementia.
ITI-007's unique pharmacology, including its activity at the serotonergic, dopaminergic, and glutamatergic systems, is associated with reduction in symptoms associated with depression. In the Phase 2 schizophrenia trial, a 60 mg dose of ITI-007 resulted in marked antidepressant effects in patients with schizophrenia and co-morbid depression. The drug's unique pharmacological activity also supports potential efficacy for the treatment of bipolar disorder and major depressive disorder.
In addition, low doses of ITI-007 have the potential to reduce behavioral disturbances in patients with dementia (including Alzheimer's disease) such as a reduction in agitation and irritability, improvements in mood and emotional stress as well as improvement in sleep. Low doses of ITI-007, up to and including 30 mg were demonstrated to be safe and well tolerated in a clinical trial of healthy geriatric subjects and elderly patients with dementia. The Company believes that these characteristics, when coupled with the drug's favorable safety and tolerability profile and the pro-social profile of ITI-007's clinical effects, result in a differentiated profile across multiple indications.
"We are undertaking a robust clinical development program for ITI-007. The key aspects of our ITI-007 program have been designed based on our understanding of the unique pharmacology of ITI-007, the strong existing clinical evidence and the supporting preclinical data. As a result, ITI-007 is being developed as a differentiated treatment in several CNS indications in which important medical needs exist," said Dr. Sharon Mates, Chairman and CEO of Intra-Cellular Therapies.
