Lenalidomide is indicated for the treatment of multiple myeloma in combination with dexamethasone. It is also indicated for the treatment of patients with transfusion-dependent anemia due to low- or intermediate- risk myelodysplastic syndromes (MDS) associated with a deletion 5q cytogenetic abnormal
The mechanism of action of lenalidomide remains to be fully characterized, however it has been demonstrated that lenalidomide inhibits the expression of cyclooxygenase-2 (COX-2), but not COX-1, in vitro. In vivo it 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
