Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - OPAL A
Treatment: Drugs - Placebo

Active comparator: OPAL A plus standard wound care -

Placebo comparator: Placebo plus standard wound care -


Treatment: Drugs: OPAL A
OPAL A will be supplied in two formulations: as a Filtrate (0.5 mL per cm2 of ulcer area, applied into the ulcer cavity) and as a Cream (about 1 to 5 g applied as a thin smear on surrounding skin). Both formulations will be applied daily. However, if the ulcer begins to hypergranulate, the OPAL A Filtrate will only be administered once every 72 hours.

Treatment: Drugs: Placebo
Placebo will be supplied in two formulations: as a Filtrate (0.5 mL per cm2 of ulcer area, applied into the ulcer cavity) and as a Cream (about 1 to 5 g applied as a thin smear on surrounding skin). Both formulations will be applied daily. However, if the ulcer begins to hypergranulate, the Placebo Filtrate will only be administered once every 72 hours.
