A pilot study of dermofilm in acute radiation-induced desquamative skin reactions.

Dermofilm (Innovatec, Australia Pty Ltd) is a topical preparation containing hydrophilic and lipophilic agents that enhance the barrier functions of damaged skin. It has been assessed in a pilot study of 50 patients with desquamative skin reactions to establish whether it is a suitable candidate to test against an existing, widely used alternative in a randomized controlled trial. Symptomatic improvement, compliance and healing time were the study endpoints. Symptomatic improvement occurred in 49 patients and compliance with the prescribing instructions was uniform. The range of healing times observed at all sites was large but a relationship with the size of the initial desquamated area was noted. It is concluded that a randomized trial comparing Dermofilm with a widely used and cheaper alternative would require a multicentre effort involving approximately 400 patients (200 per arm). Other trial design considerations are discussed.
