#### VI. Summary of Substantial Equivalence

In terms of its composition or technological characteristics, Curad®Scar Therapy is identical, and therefore substantially equivalent, to Beiersdorf's Cutinova®thin Wound Dressing, cleared for marketing under 510(k) number K94-4581. The safety of this polyurethane pad for application to both compromised and intact skin has been demonstrated with biocompatibility studies and long-term use. Thus, Curad Scar Therapy, which is applied only to intact skin, does not raise new issues of safety.

Curad® Scar Therapy has the same intended use and principle of operation as, and is therefore also substantially equivalent to, the Mepiform product. Clinical studies have demonstrated that Curad® Scar Therapy is as effective as the Mepiform in the management and reduction of hypertrophic and keloid scars. Therefore, Curad Scar Therapy does not raise new issues of efficacy.
