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 Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • A diagnosis of OA of the knee and suitable for the study as determined by a responsible physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
  • Male or female between 50 to 75 years of age inclusive.
  • A female subject is eligible to participate if she is of non-childbearing potential defined as:
  • Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MlU/ml and estradiol < 40 pg/ml (<140 pmol/L) is confirmatory].
  • Females with menopausal status ( > 12 months of spontaneous amenorrhea) and receiving hormone replacement therapy (HRT) treatment for more than 3 months.
  • BMI within the range 15-35 kg/m2 (inclusive).

  • Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • QTcB or QTcF < 450 msec; or QTc < 480 msec in subjects with Bundle Branch Block.
  • Diagnosis
  • Have a radiological and clinical diagnosis of OA based upon Arthritis Research Council (ACR) (Appendix 3) criteria affecting at least one knee of a minimum of 3 months in symptom duration prior to screening. An X-ray will be performed at screening if required.
  • Have symptomatic OA of at least one knee. The symptoms should be significantly worse in one knee than the other if OA affects both knees.
  • When questioned, confirm they experience moderate pain when climbing stairs.
  • Be able to walk unaided or with the aid of one stick (2 sticks not allowed)
  • A minimum of 4 out 10 on the NRS (numerical rating scales) at screening and/ or a requirement for the use of an analgesic for the pain in the OA knee for most days during the previous three months. In addition, baseline pain must be stable for at least 72 hours prior to day 1 based on patient's assessment or day 1 may be delayed.
  • A maximum of 8 out of 10 on the NRS at screening. Enrollement may be delayed if, in the opinion of the investigator, the severity of pain represents an isolated incident.
  • In good general health with (in the opinion of the investigator) no clinically significant and relevant abnormalities of medical history or physical examination and suitable for treatment with both naproxen and paracetamol.

Who cannot join

  • General
  • The subject has a positive pre-study drug/alcohol screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates, cannabinoids and benzodiazepines. However, a positive drug screen will not automatically exclude a subject if there is a valid explanation for the positive result other than drug abuse e.g. poppy seeds.
  • History of regular alcohol consumption within 6 months of the study defined as:
  • An average weekly intake of greater than 21 units or an average daily intake of greater than 3 units (males), or defined as an average weekly intake of greater than 14 units or an average daily intake of greater than 2 units (females). One unit is equivalent to a half-pint (220mL) of beer or 1 (25ml) measure of spirits or 1 glass (125ml) of wine.
  • Intolerance of paracetamol or not response to Non Steriodal Anti Inflammatory Drugs (NSAID) therapy.
  • The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).

About this study

Official title: A Double Blind, Randomised, Placebo Controlled Methodological Cross-over Study to Investigate the Senstivity of a Novel Study Design and Endpoints to Treatment Effects of Naproxen in Osteoarthritis

This is a methodological study designed to investigate a new model for testing pain agents in the treatment of patients with osteoarthritis (OA). This will be a double-blind, randomised, placebo controlled three-way cross-over study in patients with OA of the knee.

Read the detailed description

The study will include an interim analysis after approximately 50 patients have been randomised. Up to 100 patients with painful Osteoarthritis (OA) of the knee may be recruited into the study. Eligible subjects will wash out of all treatments for their OA pain for a minimum of 7 days apart from protocol rescue medication (paracetamol). Following this, subjects will participate in three short term treatment periods with repeated administration of Naproxen (500 mg/twice daily) or placebo for 3 days. Between treatment periods subjects will receive placebo. Endpoints will include objective assessments of function (time to walk and stair climbing) and subjective assessments of pain including current pain, the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Patient Global Impression of Change. Throughout the study subjects will be asked to rate their pain periodically. Subjects will attend the unit on Day 1 to be dispensed with study medication and to take their first dose in the unit. They will then return to the unit on Days 8, 10, 15, 17, 22 and 24 for pain assessments, with medication dispensed at each of these visits, excluding Day 24.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Naproxen in people with Osteoarthritis, run by GlaxoSmithKline at 3 sites in United Kingdom.

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 16 inclusion and 32 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 31 Jan 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

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 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?

Change from baseline in the time to ascend and descend 11 stairs (time frame: Screening, Day 1, Days 8,10,15,17,22,24). 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 31 Jan 2011; AzTrials last refreshed its copy on 29 Oct 2026.
