Association Between the Immune Checkpoint Inhibitor Durvalumab and Myasthenia Gravis: A Comprehensive Review.

Immune checkpoint inhibitors (ICIs), including Imfinzi (durvalumab), have revolutionized cancer treatment by stimulating the body's immune system to target cancerous cells. Although pharmaceuticals offer therapeutic benefits, several drugs have been associated with immune-related adverse events (irAEs), including the uncommon but serious condition known as myasthenia gravis (MG). This review synthesizes data from pertinent research to offer a thorough evaluation of the literature on the underlying mechanisms, clinical manifestations, and therapeutic approaches for durvalumab-induced MG. The incidence of MG in patients on durvalumab and other ICIs is typically low, with less than 1% documented, despite the potential for severe problems associated with the disease. Durvalumab disrupts immunological tolerance by stimulating autoreactive T-cells and inducing the production of autoantibodies. The clinical consequences of MG need meticulous monitoring, prompt identification, and suitable management to efficiently control the condition. Medical practitioners must carefully weigh the positive effects of ICIs against the possible hazards, emphasizing the necessity for more extensive investigation to improve patient results and establish uniform treatment protocols.
