QLT Inc. Announces Positive Findings From Phase IV G6PD Deficiency Study For Aczone(TM) In Acne

VANCOUVER, Nov. 7 /PRNewswire-FirstCall/ - QLT Inc. today announced positive results of a Phase IV clinical trial of Aczone(TM) in more than 50 patients with G6PD deficiency that was performed to meet a post-approval commitment requested by the FDA. The purpose of this study was to gather more information about the safety of Aczone, a prescription topical medicine, in treating patients with acne who have certain blood disorders.

During a 6-month period, patients were treated with both Aczone and the Aczone-vehicle (control group) in a cross-over design. An initial analysis of the data was undertaken by third party clinical experts in dermatology and hematology and they have concluded that no clinically meaningful changes in safety-related parameters were observed in the trial. QLT USA intends to submit a label revision supplement to the FDA during the first quarter of 2007. A decision by the FDA on the label review is expected to take approximately 10 months.

“We are pleased with the results of this Phase IV study,” said Bob Butchofsky, President and CEO of QLT. “Based on the strength of this data we plan to engage the FDA in discussions with a goal of removing the requirement for blood testing for all patients treated with Aczone. QLT USA will decide how best to commercialize the product based on interactions with the FDA.”
