Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patient with chronic low back pain who were currently receiving strong oral or transdermal opioid analgesics on a daily basis, or patients suitable for advancement of therapy to step 3 of the World Health Organization (WHO) analgesic ladder were considered for enrollment in the study. Patients requiring >8 and =96 mg of OROS® hydromorphone HCL every 24 hours were enrolled in the study.

About this study

Official title: An Open-Label, Repeated-Dose Trial to Characterize the Efficacy and Safety, and Impact on Quality of Life Measures of Dilaudid CR (Hydromorphone HCI) in Patients With Chronic Low Back Pain

The purpose of the study was to characterize the safety, effectiveness, and impact on quality of life (QOL) measures of OROS® hydromorphone HCL in patients with chronic low back pain.

Read the detailed description

This study was a short-term, non-randomized (each patient was assigned the same treatment from phase I through phase III by the researchers), non-comparative, open-label, repeated dose study of OROS® hydromorphone HCL consisting of 3 phases: Phase 1 - prior opioid stabilization phase (2-7 days); Phase 2 - OROS® hydromorphone HCL conversion, titration, and stabilization phase (3 - 14 days); Phase 3 - OROS® hydromorphone HCL maintenance therapy phase (28 days) Before Phase 1, patients must have had no change in their prescribed opioid regimen over the prior 30 days. During Phase 1, patients were to have demonstrated 2 consecutive days of stable baseline oral or transdermal opioid medication.

During Phase 2, patients requiring =96 mg OROS® hydromorphone HCL every 24 hours converted to a once-daily dosing OROS® hydromorphone HCL dose at approximately a 5:1 morphine to hydromorphone equivalent ratio. OROS® hydromorphone HCL dose titration (25-100% baseline dose) was allowed every 2 days to achieve stabilization. OROS® hydromorphone HCL dose reduction was allowed during Phases 2 and 3 for opioid-related adverse events (AEs). Rescue medication, Dilaudid IR (immediate release) was allowed during all 3 phases. During Phase 3, patients attended 4 weekly study visits to provide diary information about study medication and rescue medication usage, daily pain relief scores and adverse events, and to receive weekly supplies of study medications. OROS® hydromorphone HCL tablets of 8,16, 32, or 64 mg depending on Phase I stable baseline oral or transdermal opioid medication, 2-7 days; study drug dose titration was allowed every 2 days to achieve stabilization in Phase II, 3-14 days; Phase III , maintenance therapy phase 28 days; study drug dose reduction was allowed during Phase 2 and 3 for opioid-related adverse events. Rescue medication of Dilaudid IR (immediate release) 2, 4, 8mg tablets were allowed during all phase.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • OROS® hydromorphone HCL; Dilaudid CR (controlled release); Dilaudid IR (immediate release) as rescue medicineDrug

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The mean pain relief rating derived from daily recorded patient diaries during the 4 week maintenance phase;

Secondary outcomes (1)
  1. The overall global evaluation and Brief Pain Inventory (BPI) of study drug, as assessed by both patients and Investigators at weekly visits during the 4 week maintenance phase.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study of Low Back Pain, run by Alza Corporation, DE, USA.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Apr 2010. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The mean pain relief rating derived from daily recorded patient diaries during the 4 week maintenance phase;. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00398788, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Apr 2010.
