QLT announces that Court of Appeals grants stay of injunction against Eligard(R) sales

VANCOUVER, April 5 (HSMN NewsFeed) - QLT Inc. (NASDAQ: QLTI ; TSX: QLT ) announced today the decision of the U.S. Court of Appeals for the Federal Circuit to stay the injunction against the manufacture and sale of QLT USA Inc.'s Eligard® products that was entered on February 27, 2006, by the U.S. District Court for the Northern District of Illinois Eastern Division.

Previously, the Court of Appeals had temporarily stayed the injunction while it was considering the motion for a stay filed by QLT USA and co-defendant Sanofi-Synthelabo, Inc. Following the earlier injunction decision, QLT USA's U.S. marketing partner for Eligard, Sanofi-Synthelabo, Inc., had previously announced that it was discontinuing sales of Eligard in the U.S. until the expiry of the patent on May 1, 2006 that is the subject of the litigation with TAP Pharmaceuticals Products, Inc. As a result of the decision and reasons of the Court of Appeals to grant a stay of the injunction, Sanofi-Synthelabo has advised QLT USA it will re-launch Eligard in a limited manner in order to serve the public interest of patient safety.

Under the order issued by the Court of Appeals, QLT USA is required to deposit into escrow the net Eligard sales revenues from the date of the injunction, February 27, 2006, until the expiration of the patent on May 1.

QLT USA's appeal of the District Court's judgment on liability in favor of TAP Pharmaceutical Products Inc. and co-plaintiffs continues.
