Lenalidomide

Lenalidomide, sold under the brand name Revlimid among others, is a medication used to treat multiple myeloma, smoldering myeloma, various indolent lymphomas, and myelodysplastic syndromes (MDS). For multiple myeloma, it is a first-line treatment, and is given with dexamethasone. It is taken by mouth.

Common side effects include diarrhea, itchiness, joint pain, fever, headache, and trouble sleeping. Severe side effects include low blood platelets, low white blood cells, and blood clots. The dose may need to be adjusted in people with kidney problems. Lenalidomide is closely related to thalidomide, which is known to cause severe birth defects, so its use during pregnancy is very likely to harm the fetus.

Lenalidomide belongs to a class of drugs known as immunomodulatory imide drugs (IMiDs) or Cereblon E3 ligase modulators, which includes thalidomide and its analogs. In lymphocytes, these drugs target an E3 ubiquitin ligase and change its specificity to include new targets. This results in the rapid degradation of several disease-related proteins including IKZF1, IKZF3, and CSNK1A1.

Lenalidomide was approved for medical use in the United States in 2005. It is on the World Health Organization's List of Essential Medicines.

Lenalidomide is used to treat multiple myeloma. It is a more potent molecular analog of thalidomide, which inhibits tumor angiogenesis, tumor-secreted cytokines, and tumor proliferation through induction of apoptosis.

Lenalidomide is effective at inducing a complete or "very good partial" response and improves progression-free survival. Adverse events more common in people receiving lenalidomide for myeloma include neutropenia, deep vein thrombosis, infections, and an increased risk of other hematological malignancies. The risk of second primary hematological malignancies does not outweigh the benefit of using lenalidomide in relapsed or refractory multiple myeloma. It may be more difficult to mobilize stem cells for autograft in people who have received lenalidomide.

In 2006, lenalidomide received US Food and Drug Administration (FDA) approval for use in combination with dexamethasone in people with multiple myeloma who have received at least one prior therapy. In 2017, the FDA approved lenalidomide as standalone maintenance therapy (without dexamethasone) for people with multiple myeloma following autologous stem cell transplant.

In 2009, The National Institute for Health and Clinical Excellence issued a final appraisal determination approving lenalidomide in combination with dexamethasone as an option to treat people with multiple myeloma who have received two or more prior therapies in England and Wales.
