EDMONTON, Alberta, May 4, 2007 – Isotechnika Inc. (TSX:ISA) announced today that the Company’s lead drug, ISA247, referred to as LX211 by our partner Lux Biosciences, has been selected as the subject of two presentations at the Association for Research in Vision and Ophthalmology (ARVO) annual meeting, being held May 6-10 in Fort Lauderdale, Florida.

The first, an oral presentation being given on May 5 during a satellite session of the American Uveitis Society by Dr. Quan Dong Nguyen, Johns Hopkins University, discusses the ongoing LUMINATE (Lux Uveitis Multicenter Investigation of a New Approach to TrEatment) Phase 2/3 Clinical Trial Program. The three LUMINATE trials represent the first clinical development program aimed at supporting regulatory approval of a corticosteroid-sparing immunosuppressive agent in different types of sight-threatening, non-infectious uveitis.

The second, a poster presented by Matthew A. Cunningham, National Eye Institute, discusses preclinical data demonstrating the ability of subcutaneous injections of LX211 to prevent and reverse experimental autoimmune uveoretinitis (EAU) in rats. Cunningham commented, “We observed that in this animal model, LX211 could both prevent the onset of disease as well as reverse EAU at doses as low as 10mg/kg. These preclinical results clearly support our view that LX211 may play an important future role in the treatment of uveitis.”

“These positive preclinical results, combined with encouraging safety data from human clinical trials in other indications conducted by our partner Isotechnika, provide a strong rationale for our ongoing registration-directed LUMINATE studies of LX211 in uveitis,” said Ulrich Grau, Ph.D., Lux Biosciences’ president and chief executive officer. “We hope to complete enrollment in the LUMINATE trial program by early 2008 and, if suc
