Clinical Trial Shows Rheumatoid Arthritis Drug Could Prevent Disease

Results from a Phase 2b clinical trial, published today in The Lancet by researchers led by King’s, provides hope for arthritis sufferers after it was shown that the biologic drug abatacept reduces progression to this agonising chronic inflammatory disease.

Rheumatoid arthritis affects half a million people in the UK and develops when the body’s immune system attacks itself, causing joint pain, swelling and significant disability. The disease most commonly begins in middle age, but much younger age groups can be afflicted, and until now there is no cure or prevention.

Abatacept is currently used as an effective second or third line treatment for people living with established rheumatoid arthritis and is given by weekly injections at home or in hospital via a drip.

Researchers from King’s College London recruited 213 patients at high risk of the disease to understand whether a year-long treatment of the biologic drug could be used to prevent progression to rheumatoid arthritis.

They recruited men and women over the age of 18 with early symptoms such as joint pain but no joint swelling, and treated half with the drug and half with a placebo every week for a year. The study drug was then stopped, and study participants monitored for a further 12 months.

After twelve months of treatment, 6% of patients treated with abatacept had developed arthritis compared to 29% in the placebo arm. By 24 months, the differences were still significant, with a total of 25% progressing to rheumatoid arthritis in the abatacept arm compared to 37% in the placebo arm.

Secondary outcomes for the trial showed that abatacept was associated with improvements in pain scores, function and quality of life measurements, as well as lower scores of inflammation of the lining of joints detectable by ultrasound scan.

Philip Day, a 35-year-old software engineer and founder of FootballMatcher from Eltham, was at high-risk for rheumatoid arthritis. A keen football player, Philip’s joint pain deterred him from playing and affected his day-to-day life. He was enrolled in the trial in 2018, at the age of the 30, and was prescribed abatacept.

He said: “The pain got so terrible I stopped going to football, and I got lazier and felt progressively worse physically and mentally. The pain was unpredictable, it would show up in my knees one day, my elbows the next, and then my wrists or even my neck. At the time, my wife and I wanted to have children and I realised my future was pretty bleak if the disease progressed. I’d always wanted to be the kind of dad that played football with his son and I knew the pain would stop me from realising that dream.

“Enrolling in the trial was a no-brainer; it was a ray of hope at a dark time. Within a few months I had no more aches or pains and five years on I’d say I’ve been cured. Now, I can play football with my three-year-old son and have a normal life.”

One year’s treatment with abatacept costs the NHS about £10,000 per patient and is not without risk. Side effects include upper respiratory tract infections, dizziness, nausea and diarrhoea, but these are generally mild.

Professor Cope added: “There are currently no drugs available that prevent this potentially crippling disease. Our next steps are to understand people at risk in more detail so that we can be absolutely sure that those at highest risk of developing rheumatoid arthritis receive the drug.”

The APIPPRA trial is an Investigator-Sponsored Research (ISR) study, funded by Bristol Myers Squibb.
