The U.S. Food and Drug Administration (FDA) approved to market
Aczone (dapsone) Gel, 5 per cent for acne vulgaris topical
treatment. But patients who have the enzyme deficiency, G6PD
(Glucose 6-phosphate dehydrogenase), will need to be monitored
with regular blood counts to detect if they are predisposed to
one type of anemia (hemolytic anemia).
Aczone, a trademark of QLT USA Inc., is an aqueous topical gel
which contains 5 per cent dapsone. According to scientific
research, combining dapsone in a Solvent Microparticulate (SMP)
gel enables dapsone to be applied topically and safely. This

-in the Aczone clinical trial program- which is consistent with
the incidence in the general North American population.
The company QLT will undertake a post-approval Phase IV study in
50 acne patients who have G6PD deficiency and follow them for 6
months, after which QLT expects to submit an application to the
FDA to re-evaluate the Aczone label.
The President and Chief Executive Officer of QLT Inc., Paul
Hastings, stated that "Aczone represents an important clinical
advance in dermatology, has demonstrated safety and efficacy |
