An Observational Study to Investigate Clinical Usefulness of OROS Hydromorphone in Korean Cancer Patients

Study Overview
=================
Brief Summary
-----------------
This study aims to collect clinical information and to examine the usefulness and safety of ORal Osmotic System Hydromorphone in Korean cancer patients. The decision to treat patients with drug is as per physician discretion and that doses are determined based upon approved labeling recommendations and physician discretion.

Detailed Description
-----------------
The primary purpose of this observational study is to collect clinical data on cancer pain control using OROS (ORal Osmotic Active System) hydromorphone and to investigate the clinical usefulness of OROS hydromorphone for Korean cancer patients. Information on the effectiveness of cancer pain control and any adverse events reported by those patients using OROS Hydromorphone will be reported. In addition, clinical usefulness of OROS hydromorphone will be evaluated through assessing sleep disturbance due to pain, breakthrough pain, and end-of-dose failure before and after the study drug administration and examining the patient's satisfaction with study drug and the investigator's global assessment. This is a multi-center, open-label, prospective, exploratory, and observational study with approximately 770 patients. Efficacy endpoints will be analyzed to examine the difference between before and after the treatment. Since this is an observational study under the condition of routine practice, OROS Hydromorphone dosage should be adjusted at the discretion of the investigator, based on patient response. It is recommended that the dosage be conservative at first and adjusted appropriately considering the adverse events and analgesic effect for all the patients.
