What is "carfilzomib"

n. (context medicine English) A drug, that inhibits ubiquitination, used for the treatment of multiple myeloma

Carfilzomib (marketed under the trade name Kyprolis, developed by Onyx Pharmaceuticals) is an anti-cancer drug acting as a selective proteasome inhibitor. Chemically, it is a tetrapeptide epoxyketone and an analog of epoxomicin.

The U.S. Food and Drug Administration (FDA) approved it on 20 July 2012 for use in patients with multiple myeloma who have received at least two prior therapies, including treatment with bortezomib and an immunomodulatory therapy (such as lenalidomide) and have demonstrated disease progression on or within 60 days of completion of the last therapy. Approval is based on response rate. Clinical benefit, such as improvement in survival or symptoms, has not been verified.

The abbreviation CFZ is common for referring to carfilzomib, but abbreviating drug names is not best practice in medicine.
