Spots Global Cancer Trial Database for A Clinical Trial on Topotect® (Dexrazoxane) in the Treatment of Accidental Extravasation of Anthracyclines

Study Description

Brief Summary: The purpose of this study is * To prevent progression of a lesion caused by anthracycline extravasation into necrosis, which would require surgical intervention * To prevent development of deep tissue necrosis and destruction leading to impaired limb function and neurological deficit * To prevent postponement of the scheduled cancer treatment due to the treatment of the extravasation

Detailed Description: Accidental extravasation of anthracyclines, e.g. doxorubicin and its derivative epirubicin, may cause progressive tissue destruction including serious damage of the skin, the subcutaneous tissue, muscles, and nerves. The patient may suffer from acute local symptoms such as pain and swelling, which may progress into blistering and necrosis. Subsequently dysesthesia, skin atrophy, disfigurement, and impaired limb function may be the consequence. Surgical removal of all affected tissue is required and the debridement often necessitates split skin grafting. The patient is thus subjected to the distress of major surgery, which in turn leads to delay of further cytotoxic treatment. Preclinical animal studies as well as a clinical multicenter phase II trial have demonstrated a highly significant efficacy of dexrazoxane in preventing tissue destruction caused by anthracyclines. This confirmatory trial will determine the effect of Topotect® (dexrazoxane) as an acute antidote in patients with anthracycline extravasation. Orphan drug status TopoTarget A/S was granted designation for Topotect® as an orphan medical product for the treatment of anthracycline extravasations by the European Commission in September 2001 and by the FDA in ???. Purpose Primary objectives: • To prevent progression of the anthracycline extravasation lesion as tissue ulceration and necrosis requiring surgical intervention Secondary objectives: * To prevent development of deep tissue necrosis and destruction leading to late sequelae as impaired limb function and neurological deficit * To prevent postponement of the scheduled cancer treatment due to the treatment of the extravasation * To evaluate the tolerance to and/or toxicity of Topotect® used for this indication, according to the indicated schedule Trial design This is an open-label, non-randomised phase II/III trial. Thirty -five evaluable patients with anthracycline extravasations will be treated. Extravasation is determined by the presence of pain, and/or swelling, and/or redness at the site where anthracycline leakage is suspected to have occurred. The extravasations are subsequently confirmed in each patient by fluorescence microscopy of at least two punch biopsies at the time of the accident. Success criteria The prevention of surgical intervention, necrosis and late sequelae evaluated 3 months after the extravasation. Safety features * Toxicity caused by Topotect® will be examined by haematology and blood chemistry, questions are asked on any discomfort. Scheduled clinical examinations are performed * A systematic clinical evaluation of the marked area of skin covering the area of extravasation will be performed in order to evaluate the need for surgery * Sequential colour photographs of the involved skin will be taken Medical Treatment Patients are treated with intravenous infusion of Topotect® administered once daily on three consecutive days at the following doses: 1,000 mg/m2 + 1,000 mg/m2 + 500 mg/m2. The first dose is administered as soon as possible and within 6 hours of the extravasation and the next two doses at 24 and 48 hours after the first infusion.
