Plain English Summary
Background and study aims
Osteoarthritis (OA) is a condition that causes joints to become painful and stiff. Painful hand OA affects 13-26% of adults aged 50 and over in the UK. The National Institute of Health and Care Excellence (NICE) has recently reviewed the costs and benefits of chondroitin sulphate in OA and decided against recommending it for use in the NHS on current evidence but highlighting the need for further research. One study found that chondroitin sulphate was better than a placebo (dummy drug) and had few side effects but the improvements in patients’ pain and function after 6 months were generally small. However, this was a relatively small and short study, involving patients with more severe, advanced hand OA. Given the limited options for treatment of OA of the small joints of the hand, further research is now needed to determine whether chondroitin sulphate has long-term benefits on hand OA. To answer this question a longer term assessment of chondroitin sulphate is needed. The aim of this study is to find out whether chondroitin sulphate can improve hand pain and function over 12 months for people with hand OA.
Who can participate?
Patients aged 50 and over with hand OA
What does the study involve?
Participants are randomly allocated to one of two groups.
Participants in one group take chondroitin sulphate capsules daily for 2 years and also receive usual care. Participants in the other group take matching placebo (dummy) capsules daily for 2 years and also receive usual care. Any benefits of chondroitin sulphate may take weeks or months to emerge and so information is gathered from participants via postal questionnaires and telephone calls from a research nurse on seven occasions over a 2-year period. The calls are also an opportunity to check on how participants are getting on with their treatment and to support their involvement in the study. The focus is on the severity of hand pain over the first year, but changes in difficulties with daily activities due to the hand problem, possible side effects, other treatments, and general health are also assessed. Participants are invited to attend assessment clinics at the start of the study and at 1 and 2 years to test their hand strength. Hand x-rays are taken at the start of the study and after two years to find out whether chondroitin sulphate slows down the disease process.
What are the possible benefits and risks of participating?
Although no direct benefit can be guaranteed, all participants will receive advice and information on better managing their hand problem. The results of this study will improve the treatment of hand OA in the future. All questions, examinations and x-rays in this study are already used to assess hand pain and hand problems, and any discomfort after a hand examination should be short-lasting. Radiation doses from x-ray examinations are extremely small in relation to those received from everyday living and therefore are not associated with any significant health risk. All medications can potentially cause side effects. Chondroitin sulphate has been used as a prescription medicine for the treatment of osteoarthritis symptoms for a number of years in several European countries but is not currently licensed in the UK. The most common side effects of chondroitin sulphate are gastrointestinal disorders (nausea, abdominal pain, bloating, diarrhoea or constipation), although these are rare (experienced by less than 1 in 1,000 people). Other possible side effects are oedema (water retention) or an allergic reaction, but these are extremely rare (experienced by less than 1 in 10,000 people).

Finger osteoArthritis Chondroitin Treatment Used in addition to Advice and Leaflets
This trial is to find out whether 1200mg daily highly purified oral chondroitin sulphate, plus usual care, is effective, in terms of pain, function, structural disease progression, and cost-effective in patients with hand OA when compared to a placebo, plus usual care.
A 24-month Phase IV single-centre primary care, investigator-, practitioner- and participant-blinded, parallel-group, placebo-controlled, randomised, superiority trial of the effectiveness and cost-effectiveness of 1200mg daily highly purified oral chondroitin sulphate plus usual care for painful hand osteoarthritis in adults aged 50 years and over with a linked qualitative study

Osteoarthritis of the hand
Participants are randomised to one of two treatment groups via a web-based database:
1. Highly purified chondroitin sulphate 1200mg (3 x 400mg capsules) daily, oral, taken once per day for 2 years; plus usual care
2. Matching placebo 1200mg (3 x 400mg capsules) daily, oral, taken once per day for 2 years; plus usual care
Any benefits of chondroitin sulphate may take weeks or months to emerge and so information is gathered from participants via postal questionnaires and telephone calls from a research nurse on seven occasions over a 2-year period. The calls are also an opportunity to check on how participants are getting on with their treatment and to support their involvement in the study.
