New Cancer Therapy Helps People with Severe Rheumatoid Arthritis

Topic: Health

Scientists at Charité - Universitätsmedizin Berlin tested a new cancer therapy called CAR T-cell therapy in six people with severe rheumatoid arthritis. The results showed that the treatment was effective in reducing disease activity and helping three patients stop taking medication.

Rheumatoid arthritis is a chronic autoimmune disease where the immune system attacks the joints, causing inflammation and damage. Existing medications can control inflammation but don't cure the disease. Patients often need lifelong treatment with anti-inflammatory drugs and medications that suppress the immune system, which can have side effects.

Researchers at Charité - Universitätsmedizin Berlin wanted to see if CAR T-cell therapy could help people with severe rheumatoid arthritis. This type of therapy was originally developed to fight cancer but has potential uses in treating autoimmune diseases. The scientists tested it on six patients and found that disease activity fell substantially in every participant.

The treatment works by using a patient's own immune cells, called T cells, which are modified to recognize and destroy abnormal B cells. These abnormal B cells produce harmful antibodies that attack the body's own tissues and cause inflammation. The researchers used a special marker called CD19 to identify these abnormal B cells and created CAR T cells that can detect and eliminate them.

The patients underwent a short course of chemotherapy before receiving the modified cells, which were then infused into their bodies. Once inside, the CAR T cells searched for and attacked the abnormal B cells, temporarily removing them from the body.

Why It Matters

This breakthrough could lead to new treatments for people with severe rheumatoid arthritis in India, where millions of people suffer from this disease. It also shows the potential of cancer therapies in treating autoimmune diseases.
