Lenalidomide
REVLIMID® is an oral immunomodulatory drug marketed in the United States and many international markets, in combination with dexamethasone, for treatment of patients with multiple myeloma who have received at least one prior therapy. It is also marketed in the United States and certain international markets for the treatment of transfusion-dependent anemia due to low- or intermediate-1-risk myelodysplastic syndromes, or MDS, associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalitie.Revlimid Worldwide annual sales in 2011 was $3.2bLenalidomide (Revlimid) is a derivative of thalidomideintroduced in 2004.It was initially intended as a treatment for multiple myeloma, for which thalidomide is an accepted therapeutic treatment. Lenalidomide has also shown efficacy in the class of hematological disorders known as myelodysplastic syndromes (MDS). Lenalidomide has significantly improved overall survival in myeloma (which generally carries a poor prognosis), although toxicity remains an issue for users. [1]It costs $163,381 per year for the average patient.[2]
Lenalidomide has been used to successfully treat both inflammatory disorders and cancers in the past 10 years. There are multiple mechanisms of action, and they can be simplified by organizing them as mechanisms of action in vitro and in vivo.[3] In vitro, lenalidomide has three main activities: direct anti-tumor effect, inhibition of the microenvironment support for tumor cells, and immunomodulatory role. In vivo, lenalidomide induces tumor cell apoptosis directly and indirectly by inhibition of bone marrow stromal cell support, by anti-angiogenic and anti-osteoclastogenic effects, and by immunomodulatory activity. Lenalidomide has a broad range of activities that can be exploited to treat many hematologic and solid cancers.
