Lenalidomide, also known as its trade name Revlimid, is currently a mainstay in multiple myeloma treatment. In newly diagnosed patients, standard doses of lenalidomide, in combination with other therapies, is used to kill myeloma cells. Later on in treatment, low doses of lenalidomide is used to keep the immune system on high alert in case the cancer begins to come back following chemotherapy.
However, thalidomide, the precursor to lenalidomide, was initially not developed as a treatment for multiple myeloma. “The story of thalidomide is one of the most fascinating stories in all of medicine,” remembers Dr. Vincent Rajkumar, medical oncologist at the Mayo Clinic and one of the key players in getting lenalidomide federally approved for multiple myeloma treatment. “Thalidomide was developed as a sleeping pill in the late 50s. And when it was developed nobody knew its precise mechanism of action. They just knew that if you took it, you felt sleepy.”
