About Abstral™

It is based on Orexo´s unique and patented sublingual tablet technology in which a rapidly disintegrating tablet is placed under the tongue and the active substance is absorbed by the mucous membrane.

About Breakthrough Cancer Pain

Breakthrough pain ("BTP”) is an acute and often severe flare of pain experienced by patients treated with round the clock opioid analgesics for their underlying chronic cancer pain. It is known as breakthrough pain because it is pain that "breaks through" a regular pain medicine schedule. For some patients, breakthrough pain occurs during certain everyday activities, such as walking or dressing. For others, it occurs unexpectedly without any apparent cause.

Between 64% and 89% of patients with cancer experience an average of 4-7 BTP episodes per day. In a recent survey of patients with cancer BTP:

•  89% stated that BTP negatively affected their quality of life
•  73% stated that BTP wakes them from a deep sleep at least once a month
•  76% stated that BTP affects their ability to perform everyday household chores
•  75% stated that BTP is one of the most challenging effects of having cancer
•  35% stated that BTP affects their relationships with their family members
•  82% stated that BTP negatively affects their emotional health
