The US Food and Drug Administration approved a new treatment for dermatomyositis on 27 August – the first oral drug for a disease that can cause progressive damage to the muscles, skin and lungs and an impaired quality of life. Existing treatments include combinations of chronic steroids and antirheumatic drugs which have not been effective in controlling the disorder. The new treatment, Lisraya (brepocitinib), works as a Janus kinase inhibitor, blocking pathways that play a key role in the body’s immune responses.
