Raylumis

Raylumis was developed as a medicine to treat moderate to severe chronic pain of the hip or knee in adults with osteoarthritis. Raylumis was intended for patients whose disease cannot be controlled well enough with non-steroidal anti-inflammatory drugs (NSAIDs) or opioids (a painkiller related to morphine) or patients who cannot take these medicines. 

Raylumis contains the active substance tanezumab and was to be available as a solution for injection under the skin.

The active substance in Raylumis, tanezumab, is a monoclonal antibody (a type of protein) that has been designed to recognise and attach to a protein called nerve growth factor (NGF). NGF is involved in the control of pain and is elevated in joints of osteoarthritis patients. Tanezumab is intended to block NGF from attaching to specific receptors (targets) on nerve cells that control pain and is expected to relieve pain associated with osteoarthritis.

The company presented the results from three main studies involving 3,021 patients with moderate to severe chronic pain in knees or hips and moderate to severe problems with the normal functioning of the joints, due to their osteoarthritis. The studies compared the effects of Raylumis on pain and physical function with that of placebo (a dummy treatment) or, in one study, NSAIDs.

Although Raylumis showed better pain relief and improved physical functioning in patients with osteoarthritis affecting the hip or knee compared with placebo, the difference was small. In addition, there was no improvement in pain relief and physical functioning when compared with NSAIDs. In terms of safety, patients on Raylumis were at an increased risk of side effects, such as rapid progressive osteoarthritis and joint replacement, compared with patients receiving placebo or NSAIDs. Therefore, the Agency’s opinion was that the benefits of Raylumis in patients with an insufficient response to NSAIDs or opioids were unclear and did not outweigh its risks and recommended refusing marketing authorisation.

The company informed the Agency that there are no consequences for patients in clinical trials with Raylumis.
