 News Release - April 25, 2007

QLT announces that CHMP will recommend to the European Commission that occult indication be deleted from the Visudyne(R)label in European Union

Other Visudyne indications not affected by the CHMP Opinion

VANCOUVER, April 25 (HSMN NewsFeed) - QLT Inc. (NASDAQ: QLTI ; TSX: QLT ) announced today that it has been informed that the Committee for Medicinal Products for Human Use (CHMP) will recommend to the European Commission that the indication of the use of Visudyne® in the treatment of occult subfoveal choroidal neovascularization (CNV) secondary to Age-related Macular Degeneration (AMD) be deleted.

The European Commission is expected to endorse the CHMP's recommendation in a final decision that should be issued within approximately two months. Such a decision by the European Commission is not expected to affect the approved use of Visudyne in the predominately classic or pathologic myopia indications.

The CHMP opinion was based on its review of data from the Visudyne in Occult (VIO) trial that, as announced in September 2005, did not achieve the significance level required of its primary end points. The VIO study was undertaken in part at the request of the CHMP to confirm the results of an earlier trial, Visudyne In Photodynamic Therapy (VIP), that demonstrated evidence of efficacy in the occult patient population. The initial marketing authorization in Europe was based on two-year results from the VIP study. Although the VIO trial did not achieve statistical significance in its primary end points, the data from the trial was not inconsistent with the positive results seen in the VIP study. However, the CHMP has recommended the deletion of the occult CNV indication on the Visudyne label based on lack of confirmation of the VIP efficacy results in the VIO study. No safety concerns were raised. The opinion is expected to be published on the EMEA web site by Friday, April 27.

It is unclear what effect this decision will have on European Visudyne sales. The outcome will depend on the extent to which countries in the European Union change their reimbursement policies as well as market adoption following the results from combination use studies currently being undertaken.
