Topoisomerase enzymes are essential for cell growth and proliferation and the target for a group of anti-cancer chemotherapeutics called anthracyclines. Savene®/Totect® blocks the activity of the topoisomerase enzyme and prevents the effect of anthracyclines. Savene®/Totect® is used as a detoxifying agent, administered intravenously as an antidote following an extravasation. An extravasation is a serious clinical accident in which anthracyclines accidentally leak into surrounding tissue. The high concentration of drug causes severe and cumulative damage to the skin, subcutaneous tissue, muscle and nerves. Current treatment often involves surgical removal of the tissue followed by plastic surgery and rehabilitation. The use of dexrazoxane (the active ingredient in Savene®/Totect®) to treat anthracycline extravasation is protected by patent in several countries including EU and the US. The US patent number is 6,727,253 B2.
