  • The new cancer drug Beksmarilimab revives the immune response in tumors

    The new cancer drug Beksmarilimab revives the immune response in tumors

    Bexmarilimab works by stimulating macrophages, a type of white blood cell, in the tumor. These cells then alert other cancer-fighting cells to the presence of the tumor. Traditional cancer immunotherapies focus on enhancing the body's defense system and often target T cells. However, these treatments do not work for all patients, highlighting the need for…
