Trial summary

Osteoarthritis is the most common form of arthritis worldwide. Specifically, osteoarthritis of the hands affects millions of people and is a major cause of hand disability and pain. Despite this, there are currently no treatments that delay or halt the development of osteoarthritis. Read more about this study

About this study

Osteoarthritis is the most common form of arthritis worldwide. Specifically, osteoarthritis of the hands affects millions of people and is a major cause of hand disability and pain. Despite this, there are currently no treatments that delay or halt the development of osteoarthritis. Pain is one of the major symptoms of osteoarthritis and pain management is an important factor to consider in the treatment of this condition. Treatments for pain in osteoarthritis consists of local injections, anti-inflammatory gels or painkillers such as paracetamol. However, most people with osteoarthritis still have pain despite these treatments.

Read the detailed description

Recent scientific studies have suggested that people with hand osteoarthritis not only feel pain in their hand joints, they also appear to have increased signals in their brain pain processing pathways. At St George's, University of London, the investigators have been conducting studies to find out which brain regions are activated in subjects with hand osteoarthritis. The investigators have found that certain brain regions (thalamus, insula, cingulate and somatosensory cortex) are activated during painful tasks in patients with hand osteoarthritis but not in healthy people. In this study the investigators will establish whether drugs that inhibit pain processing pathways in the brain can help. Patients who are still having pain despite their usual painkillers will be randomly divided into 3 groups: one group will receive a placebo, the other 2 groups will receive one of two different drugs, duloxetine or pregabalin. Participants will be assessed using questionnaires and a brain scan (functional MRI) before and after 13 weeks of taking the tablets. This study will help us to understand the ways in which people feel pain in osteoarthritis. If our trial proves successful,drugs that dampen central pain pathways could be used in combination with local pain-relieving drugs to improve treatment and reduce disability in patients with hand osteoarthritis.

What participants receive

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

  • Pregabalin or Duloxetine or PlaceboDrug

    Also called DUPRO Capsules

    This is a randomized, double blind placebo controlled trial with a head-to-head comparison of duloxetine vs pregabalin vs placebo over-encapsulated to prevent unblinding of treatment arm

What is being measured

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

  1. Australian/Canadian Hand Osteoarthritis Index score (AUSCAN)

    The AUSCAN measures pain and hand function. Differences between baseline AUSCAN and after treatment will be recorded for each participant to assess for improvement in AUSCAN pain and function score after the trial intervention.

    Measured: 12 weeks

Secondary outcomes (1)
  1. Brain magnetic resonance imaging (MRI)

    Changes between baseline MRI and post-treatment after 12 weeks of intervention will be measured using functional neuroimaging to assess pain center activation before and after intervention.

    Measured: Baseline and 12 weeks after treatment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study of Hand Osteoarthritis, run by St George's, University of London at 1 site 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 6 inclusion and 6 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 20 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 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?

Australian/Canadian Hand Osteoarthritis Index score (AUSCAN) (time frame: 12 weeks). 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 20 Jul 2016.
