About this study

Official title: Randomized, Double-blind and Placebo-controlled Evaluation of Efficacy and Safety of Naproxen Sodium and Codeine Phosphate Combination in Osteoarthritis

Osteoarthritis (OA) pain treatment has limitations in terms of serious adverse effects and low efficacy. The investigators aimed to evaluate efficacy and safety of naproxen sodium/codeine phosphate combination in these patients.

Read the detailed description

In this prospective, randomized, double blind, placebo controlled clinical trial, 135 patients with osteoarthritis, who were 40-65 years; applied to institution's orthopaedics outpatient clinic; had grade 1, 2, or 3 primary osteoarthritis diagnosed in last 1 year; and had Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score≥40, and Visual Analogue Scale score≥40,were enrolled. Subjects were randomized (1:1) to placebo (n= 67) or combination (n= 68) arms, in which 550 mg naproxen sodium/30mg codeine phosphate was given orally twice a day for 7 days. Rescue medicine was 500 mg paracetamol (max= 6 tablets/day). Demographic characteristics, medical history, adverse events, VAS and WOMAC scores were collected in study visits performed within 10days.The study was approved by local institutional ethics committee and written informed consents were obtained from all participants.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Naproxen Sodium Codeine in people with Osteoarthritis, run by Istanbul Medeniyet University.

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 6 inclusion and 16 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 25 Feb 2016. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Change in Western Ontario Mac Master Questionnaire (WOMAC) (time frame: 7 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Feb 2016.
