Actemra (tocilizumab) is a biological medicine approved by the FDA, and it can be administered intravenously or by injection under the skin to treat patients suffering from COVID-19, rheumatoid arthritis, giant cell arteritis, scleroderma, polyarticular or systemic juvenile idiopathic arthritis, and severe cytokine release syndrome.

On December 21, 2022, the FDA approved Actemra for treating COVID-19 in specific adult patients. Actemra is still available under emergency use authorization (EUA) for pediatric patients with COVID-19.
Actemra is a monoclonal antibody that blocks interleukin-6 (IL-6) in your body. Inflammation and the symptoms of autoimmune disease result when this protein is activated, causing your immune system to be overactive. Actemra reduces the immune system’s overactivity by blocking the interleukin-6 receptor, resulting in less inflammation and autoimmune symptoms.

The mechanism of action (MOA) of Actemra is that it binds to IL-6 receptors (sIL-6R and mIL-6R) that inhibit IL-6-mediated signaling. Interleukin-6 is a pro-inflammatory cytokine made by various cell types, including T- and B-cells, lymphocytes, monocytes, and fibroblasts.

Rheumatoid Arthritis

Rheumatoid Arthritis, often abbreviated as RA, is a chronic autoimmune disorder that primarily affects the joints, causing inflammation, pain, and joint damage over time. Unlike osteoarthritis, which results from wear and tear on joints, RA occurs when the immune system mistakenly attacks healthy joint tissues. This leads to inflammation in the synovium—the lining of the membranes that surround joints—which eventually damages the joint itself, leading to pain, stiffness, and reduced mobility.

Living with Rheumatoid Arthritis can have a significant impact on one’s quality of life. The condition commonly targets smaller joints, such as those in the hands and feet, but it can also affect larger joints and even other parts of the body. Beyond physical symptoms, RA can contribute to fatigue, decreased appetite, and an increased risk of complications in organs like the heart and lungs.

Rheumatoid Arthritis presents a range of symptoms that can vary in severity from person to person. These symptoms include:

  • Joint pain and stiffness, especially in the morning or after periods of inactivity
  • Swelling and tenderness around affected joints
  • Warmth and redness around the joints
  • Fatigue and general weakness
  • Low-grade fever
  • Loss of appetite
