Evaluation of the Efficacy and Safety of Fentanyl Delivered by Adhesive Skin Patch in Out-Patients With Chronic Cancer Pain
The purpose of this study is to determine the safety and efficacy of pain control by fentanyl, administered via adhesive skin patches, at doses of 25 to 100 micrograms per hour in 80 out-patients with intense chronic cancer pain. Higher doses are allowed by permission of the investigator and rescue oral morphine medication is allowed.

|Official Title:||Evaluation of the Efficacy and Safety of Transdermal Fentanyl in Patients Suffering From Chronic Cancer Pain in an Ambulatory Setting|
- Pain control level using a visual analog scale (VAS) at various time points and at the end of 56-day study. Percent pain reduction and percentage of patients having a score of 4 or lower compared to the baseline. Use of rescue medication.
- Constipation and recorded use of laxatives, patient-assessed quality of life obtained by questionnaires and overall tolerance assessed at the end of 56-day study.

Patients with cancer pain are frequently under-medicated with morphine. This is a 56-day open-label study of the efficacy and safety of self-administered fentanyl skin patches for cancer pain control in patients in the home-care setting not previously using morphine. The first 15 days of the study are for dose stabilization and the rest of the study assesses pain control and quality of life at stable doses of medication. The dose is determined by the patient with oversight by the investigator, and rescue oral morphine medication can be used when necessary. The patient records all medication use in a diary and fills out questionnaires concerning pain control, intestinal function (constipation) and overall quality of life. The hypothesis is that patients will be able to control their cancer pain by self-administering transdermal fentanyl at home and that they will well tolerate the medication.
Individualized doses, with a target dose of 25 to 100 micrograms per hour of fentanyl for 56 days via skin patches applied every 3 days to deliver 25 to 100 micrograms of fentanyl per hour per patch; oral morphine as rescue medication for pain.
