Study Findings Presented at the 22nd European Congress of Psychiatry (EPA 2014) in Munich

MUNICH, Germany I March 3, 2014 I Sunovion Pharmaceuticals Inc. (“Sunovion”) (Head Office: Marlborough, Massachusetts) and Takeda Pharmaceutical International GmbH (“Takeda”) (Zurich, Switzerland) today announced the results from a double-blind, placebo-controlled study that evaluated the efficacy, safety and tolerability of lurasidone for the maintenance treatment of adults with schizophrenia. Lurasidone is a once-daily oral atypical antipsychotic indicated for the treatment of adults with schizophrenia and is currently available in the United States, Canada and Switzerland. The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) issued a Positive Opinion for lurasidone for the treatment of schizophrenia in adults on January 23, 2014.

In the double-blind, placebo-controlled, randomized withdrawal study, adult patients with schizophrenia who were stabilized on lurasidone (40-80 mg/day, flexibly dosed) during open-label treatment were randomized to either continued treatment with lurasidone (40 mg/day or 80 mg/day, flexibly dosed) or placebo for up to 28 weeks.1 The primary endpoint was time to relapse over 28 weeks of the double-blind phase. The study showed that patients who received lurasidone (N=144) experienced a significant delay in time to relapse compared to patients who received placebo (N=141) (p=0.039).1 Treatment with lurasidone was associated with a 33.7% reduction in risk of relapse vs. placebo (hazard ratio 0.663, 95% CI [0.447, 0.983]; p=0.041).1

The study demonstrated that lurasidone was generally well-tolerated and had low rates of weight increase, as well as lipid and glucose effects.1 It is important to minimize the adverse effects on long-term physical health of schizophrenia as patients are likely to remain on therapy for many years.

The discontinuation rate due to adverse events during the double-blind phase in patients treated with lurasidone was 13.9% vs. 15.6% for placebo.2 In patients who completed the open-label stabilization phase (12 to 24 weeks) and were randomized to continued treatment with lurasidone in the double-blind phase (up to 28 weeks), the most common treatment-emergent adverse events (incidence >10%) were akathisia (16.7%), insomnia (12.5%), headache (11.8%), nausea (11.1%) and anxiety (11.1%).2

“Schizophrenia is a chronic condition that is severe and disabling, so it is important that healthcare providers not only address the acute symptoms of the illness, but also minimize the risk of experiencing relapse, a common challenge with the disorder,” said Rajiv Tandon, M.D., Vice Chair and Professor of Psychiatry at the University of Florida College of Medicine, Chief of Psychiatry at the North Florida/South Georgia Veterans Health System, Florida, United States and lead author on the study. “This study supports the efficacy of lurasidone in preventing relapse while producing few changes in weight, lipids and measures of glycemic control.”

These data were submitted to the EMA for potential inclusion in the Summary of Product Characteristics. These study results will also be submitted to relevant Health Authorities for review and potential inclusion in the respective prescribing information.

“Lurasidone has demonstrated efficacy and safety in a number of short-term studies of adults with schizophrenia,” said Antony Loebel, M.D., Executive Vice President and Chief Medical Officer at Sunovion Pharmaceuticals Inc. “We are pleased to see the results of this study confirm the long-term efficacy of lurasidone in schizophrenia. In addition, long-term effects on metabolic parameters were consistent with the findings of short-term studies.”

About Schizophrenia

Schizophrenia is a chronic, serious and often severely disabling brain disorder that affects approximately 24 million people worldwide.3 Schizophrenia is characterized by symptoms such as hallucinations, delusions, disorganized thinking, lack of emotion and lack of energy, as well as problems with memory, attention and the ability to plan, organize and make decisions.4 Patients with schizophrenia have a life span that is decreased by approximately 10–22.5 years compared with the general population.5,6,7,8

Direct and indirect costs associated with caring for patients with schizophrenia are considerable and can include utilization of other health services, pharmacotherapy, community care, supportive therapy, informal care and private expenditures, and patient and caregiver lost productivity.9,10 Hospitalization associated with patient relapse can significantly increase costs associated with disease management in schizophrenia.11

Antipsychotics are considered to be the cornerstone of treatment for patients with schizophrenia, with agents generally classified as typical or atypical. Atypical agents are broadly considered to have safety and tolerability benefits over typical agents.12 Long-term and maintenance treatment of schizophrenia remains challenging due to multiple problems related to compliance, efficacy, safety and tolerability, which vary among different medications.13

About Lurasidone

Lurasidone is an atypical antipsychotic developed originally by Dainippon Sumitomo Pharma Co., Ltd. The efficacy of lurasidone may be mediated through a combination of central dopamine Type 2 (D2) and serotonin Type 2 (5HT2A) receptor antagonism.

Lurasidone, marketed as Latuda®, is approved for the treatment of schizophrenia in the United States, Canada and Switzerland.

The CHMP of the EMA issued a Positive Opinion for lurasidone for the treatment of schizophrenia in adults on January 23, 2014.

A marketing application has been filed for lurasidone with the Australian Therapeutic Goods Administration and the Taiwan Food and Drug Administration.
