European Medicines Agency Accepts HETLIOZ™ (tasimelteon) Marketing Authorization Application for Non-24-Hour Sleep-Wake Disorder in the Totally Blind

WASHINGTON, June 3, 2014 -- Vanda Pharmaceuticals Inc. (Vanda) (VNDA) announced today that its Marketing Authorization Application (MAA) for oral HETLIOZ™ (tasimelteon) capsules has been accepted for evaluation by the European Medicines Agency (EMA) for the treatment of Non-24-Hour Sleep-Wake Disorder (Non-24).

"The EMA submission is an important milestone towards providing a treatment option for people living with Non-24 in the European Union," said Mihael H. Polymeropoulos, M.D., Vanda's President and CEO. "This continues our efforts to expand the availability of HETLIOZ to markets outside the U.S."

HETLIOZ™ has been granted orphan drug designation for the treatment of Non-24 in blind people with no light perception from the European Commission. HETLIOZ™ was approved by the FDA in January 2014 and is available through specialty pharmacies in the U.S.

About Non-24-Hour Sleep-Wake Disorder 
Non-24 was first described more than 60 years ago, and is a chronic, circadian rhythm disorder resulting from the misalignment of the endogenous master body clock to the 24-hour day, disrupting the sleep-wake cycle. The sleep disturbance causes significant distress or impairment in social, occupational and other important areas of functioning. Non-24 affects the majority of totally blind individuals and it is estimated that approximately 130,000 people in the European Union have the disorder.

U.S. Indication and Important Safety Information About HETLIOZ™

Indication
HETLIOZ™ is indicated for the treatment of Non-24-Hour Sleep-Wake Disorder (Non-24).

Important Safety Information
HETLIOZ™ may cause somnolence:  After taking HETLIOZ™, patients should limit their activity to preparing for going to bed, because HETLIOZ™ can impair the performance of activities requiring complete mental alertness.

The most common adverse reactions (incidence >5% and at least twice as high on HETLIOZ™ than on placebo) were headache, increased alanine aminotransferase, nightmares or unusual dreams, upper respiratory or urinary tract infection. The risk of adverse reactions may be greater in elderly (>65 years) patients than younger patients because exposure to HETLIOZ™ is increased by approximately 2-fold compared with younger patients.

Use of HETLIOZ™ should be avoided in combination with fluvoxamine or other strong CYP1A2 inhibitors, because of a potentially large increase in exposure of HETLIOZ™, and a greater risk of adverse reactions. HETLIOZ™ should be avoided in combination with rifampin or other CYP3A4 inducers, because of a potentially large decrease in exposure of HETLIOZ™, with reduced efficacy.

There are no adequate and well-controlled studies of HETLIOZ™ in pregnant women. Based on animal data, HETLIOZ™ may cause fetal harm. HETLIOZ™ should be used during pregnancy only if the potential benefit justifies the potential risks. Caution should be exercised when HETLIOZ™ is administered to a nursing woman.

HETLIOZ™ has not been studied in patients with severe hepatic impairment and is not recommended in these patients.

Safety and effectiveness of HETLIOZ™ in pediatric patients have not been established.
