Lenalidomide

Lenalidomide is an immunomodulatory and antineoplastic agent used for the treatment of multiple myeloma, myelodysplastic syndromes, and mantle cell lymphoma. It works by inhibiting the growth of cancer cells, stimulating the body’s immune response, and preventing the formation of new blood vessels in tumors. Lenalidomide is used both in combination with other therapies and as monotherapy, improving patient survival and quality of life.
