Amrubicin (INN; previously known as SM-5887) is an anthracycline used in the treatment of lung cancer.[1] It is marketed in Japan since 2002 by Sumitomo Pharmaceuticals under the brand name Calsed.[2]

Amrubicin acts by inhibiting topoisomerase II, and has been compared in clinical trials with topotecan, a Topoisomerase I inhibitor.[3] [4]

It has also been studied for the treatment of bladder carcinoma[5] and gastric cancer.[6]
