Palifermin reduces severe mucositis in head and neck cancer
Source: http://www.medscape.com/ Author: Janis C. Kelly Palifermin (Kepivance), which is currently approved for preventing mucositis associated with total-body irradiation and stem-cell transplantation in hematologic malignancies, also prevents oral mucositis in patients with head and neck cancer undergoing radiation and chemotherapy, according to 2 randomized trials published online June 13 in the Journal of Clinical Oncology. Michael Henke, MD, who led both studies, told Medscape Medical News that "this shows for the first time that radiation-induced mucositis can be ameliorated — and this in a phase 2/3 design!" Dr. Henke is from the Department of Radiation Oncology at University Clinic in Freiburg, Germany. The multicenter studies included researchers from Austria, France, Germany, Hungary, Italy, Poland, Spain, the United Kingdom, and the United States. The first study was a double-blind randomized placebo-controlled trial of 186 patients with stage II to IVB carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx. Treatment included radiation, 60 or 66 Gy, after complete or incomplete resection, delivered at 2 Gy per fraction and 5 fractions per week. Treatment also included cisplatin 100 mg/m2 on days 1 and 22 (and on day 43 with incomplete resection). Patients were randomized to weekly palifermin 120 μg/kg or placebo from 3 days before and throughout radiochemotherapy. The primary end point was the incidence of severe oral mucositis (World Health Organization [WHO] grades 3 to 4). Palifermin reduced oral mucositis incidence to 51% (41 of 92), compared with 67% (63 of 94) with placebo (P = .027), shortened median mucositis from [...]
