Efficacy of Wobe-Mugos E for reduction of oral mucositis after radiotherapy : results of a prospective, randomized, placebo-controlled, triple-blind phase III multicenter study.

To investigate the efficacy and safety of Wobe-Mugos E (proteolytic enzymes) for amelioration of early side effects of radiotherapy for head-and-neck tumors, particularly oral mucositis. The study was a prospective, randomized, multicenter, placebo-controlled, triple-blind phase III study with parallel groups. 69 patients with carcinomas of the oropharynx or the oral cavity were enrolled between 1996 and 2000 in five centers; 54 of these were recruited in Dresden. Of the 69 patients, 61 (Dresden: 46) were available for analysis. The proteolytic enzymes tested (Wobe-Mugos E) comprised papain 100 mg, trypsin 40 mg, and chymotrypsin 40 mg. Wobe-Mugos E was well tolerated. For the maximum mucositis scores, no statistically significant differences were found between the placebo and the verum group. The average mucositis score over weeks 1-6 revealed a significant difference in favor of the placebo arm, based on an earlier onset of mucositis in the Wobe-Mugos E group. The present study failed to demonstrate any effect of treatment with Wobe-Mugos E on radiotherapy side effects in patients treated for head-and-neck tumors. In particular, there was no beneficial effect on radiation-induced early oral mucositis.
