Clinical Investigation of Sorbact® Dressings

This is a prospective, open, single-centre, exploratory clinical investigation with a primary objective of studying the binding of bacteria and fungi from hard-to-heal wounds to the surface of DACC-coated dressings.

Subjects suffering from hard-to-heal wounds who are due to start using a dressing from the Sorbact range will be recruited at one investigation site in Sweden. The subjects will be divided into three groups by dressing type and there will be 10 subjects in each group, i.e., 10 subjects will be treated with Sorbact® Compress, 10 subjects will be treated with Sorbact® Gel Dressing, and 10 subjects will be treated with Sorbact® Ribbon Gauze. The dressings will be used in accordance with their respective IFU.

The clinical investigation is designed to have a treatment period of 14 days with no additional follow-up.

Three visits are planned for each subject, including a screening/baseline visit at the clinic and two further visits to the study clinic.
