About this study

Official title: A Randomized, Double-Blind, Active-Control, Parallel-Group, 90-Day Safety Study of CG5503 Immediate Release (IR) or Oxycodone IR in Subjects With Chronic Pain From Low Back Pain or Osteoarthritis of the Hip or Knee

The purpose of this study is to evaluate the safety of CG5503 base Immediate Release(IR) 50 mg or 100 mg taken every 4 to 6 hours as needed over the long-term exposure of 90 days in patients who have chronic pain.

Read the detailed description

CG5503 is a centrally active pain-relieving drug being investigated for the treatment of acute and chronic pain. This study is designed to assess the safety of CG5503 Immediate Release (IR) in men and women who are 18 years of age or older and who have had chronic (for at least 3 months) low-back pain or chronic pain from osteoarthritis of the hip or knee, and who require daily analgesic medication. In this double blind study (neither patients nor investigators will know what treatment is given), patients will be randomly (patients are assigned different treatments based on chance) assigned to receive either CG5503 base IR or oxycodone IR to begin a 90 day treatment during which each patient will return to the medical facility every 2 weeks. For the CG5503 IR group, patients will take 50 or 100 mg orally every 4 to 6 hours as needed to a maximum dose of 600 mg per day. Oxycodone IR patients will take 10 or 15 mg orally every 4 to 6 hours as needed to a maximum dose of 90 mg per day. Patients may continue taking their regular, stable, non-opioid medication throughout the study. The effectiveness of study treatment (CG5503 base IR or oxycodone) will be assessed with 11-Point Numerical Rating Scale and Patient Global Impression of Change. Using these scales, patients will indicate their pain intensity level and overall status of their well-being. Opioid withdrawal symptoms of CG5503 IR dose of 50 or 100 mg will be assessed with clinical opioid withdrawal scale [Subjective Opiate Withdrawal Scale (SOWS) and Clinical Opiate Withdrawal Scale (COWS)] at the end of treatment. Using these scales, patients will indicate the physical components of drug withdrawal and the severity of symptoms associated with rapid withdrawal. Safety will be assessed using physical examination, monitoring of adverse events, clinical and laboratory measures, and 12 lead electrocardiogram (ECG) results. Constipation, vomiting, and sleep assessments will be performed. No formal hypothesis testing will be done in this study. For the CG5503 IR group, patients will take a flexible dose of 50 or 100 mg orally every 4 to 6 hours as needed to a maximum dose of 600 mg per day for 90 days. Oxycodone IR patients will take a flexible dose of 10 or 15 mg orally every 4 to 6 hours as needed to a maximum dose of 90 mg per day for 90 days.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing CG 5503;tapentadol in people with Osteoarthritis and Pain Intensity Assessment, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..

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 3 inclusion and 5 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 9 Jun 2011. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 primary outcomes include incidence of adverse events, changes in laboratory measures, results of physical exams, and results of 12-Lead ECG.. 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 NCT00364546, which also lists 2 linked publications.

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 9 Jun 2011.
