A Study of the Effectiveness and Safety of Sustained-release Hydromorphone (a Strong Opioid) in Patients With Chronic Noncancer Pain.

Randomized, Open-Label, Comparative Parallel Group Study to Assess Efficacy and Safety on Flexible Dosages of OROS Hydromorphone Once-Daily Compared to Sustained Release Oxycodone Twice Daily in Subjects With Chronic Non-malignant Pain Requiring Continuous Opioid Therapy.

The purpose of this study is to compare the effectiveness and safety of sustained- release hydromorphone, formulated to release slowly over time, taken once daily, and controlled- release oxycodone taken twice daily, in patients with chronic non-cancer pain. The study will also determine the dose of sustained-release hydromorphone that provides a level of pain control that is equal to the pain control provided by control-released oxycodone (equi-analgesic dosage).

Study Overview

• Status: Completed
• Conditions: Pain
• Intervention / Treatment: Drug: Oxycodone; Drug: OROS hydromorphone HCl

Detailed Description

Conventional immediate-release forms of hydromorphone and oxycodone have a relatively short duration of action that require dosing every 4 to 6 hours. To counterbalance the drawback of repeated opioid intake, sustained-release formulations of oxycodone and hydromorphone were developed that allow twice-daily dosing. Subsequently, a novel, once-daily, extended-release hydromorphone formulation was developed to further enhance ease of treatment and improve effectiveness in the treatment of severe pain. This is a randomized, open-label, comparative, parallel-group, 24-week flexible-dose study in patients with chronic noncancer pain severe enough to require continuous opioid therapy. Patients will receive either 8 mg of sustained-release hydromorphone, taken once daily or 10 mg of controlled-release oxycodone, taken twice daily. Individual adjustments in dosing will be performed to achieve satisfactory pain control, up to a maximum daily dosage of 32 mg for hydromorphone and 80 mg for oxycodone. The primary efficacy outcome will be the determination of the dose of hydromorphone that produces a level of pain control that is equal to the pain control provided by oxycodone (equi-analgesic dose). Safety will be monitored throughout the study. The study hypothesis is that sustained-release hydromorphone taken once daily is well tolerated and is not inferior with regard to pain control to controlled-release oxycodone taken twice daily.

Amendment:

Amendment was made to the duration of the study from duration of '24 weeks' to '52 weeks' in order to collect long-term safety and efficacy data. OROS hydromorphone 8, 16, or 32 mg tablets QD or SR oxycodone 10, 20, or 40 mg tablets BID. Individual adjustments in dosing performed to achieve satisfactory pain control over 24 weeks. Amendment: treatment duration was extended to 52 weeks.

Change in Dose of Study Treatment During Titration Phase (First 4 Weeks of Study) and Overall Treatment Phase I (First 24 Weeks of Study)	Number of subejcts with change in dose of study treatment was assessed and stratified by time on study, at least 4 weeks versus dropped out at highest dose before week 4, at weeks 4 and 24.	weeks 4 and 24
Number of Drop-outs	Number of drop-outs according to reasons for drop-out and due to inefficacy at maximal dosage was assessed at weeks 24 and 52.	baseline to week 24 (core); week 24 to week 52 (extension)
