Isotechnika Inc. Announces Nine Month Safety Data From The Phase III Psoriasis Trial For ISA247

EDMONTON, Dec. 8 /PRNewswire-FirstCall/ - Isotechnika Inc. (TSX:ISA - News) announced today nine month interim safety and efficacy data obtained from its 24 week Phase III psoriasis trial and 12 week extension for its lead immunosuppressive drug, ISA247.

Patients completing the 24 week Canadian Phase III SPIRIT trial were given the opportunity to continue therapy for an additional 36 weeks or to discontinue therapy. Ninety percent of patients who completed the trial chose to enroll in the extension trial. Those patients who chose to enroll in the extension trial were moved from the 0.2 mg/kg (low dose) or 0.4 mg/kg (high dose) bid dose groups into the 0.3 mg/kg bid (mid dose group). Patients who commenced the SPIRIT trial in the 0.3 mg/kg bid dose group remained on the same dosage regimen for the duration of the extension trial. The goals of the extension trial are to demonstrate continued therapeutic benefit to psoriasis patients and to gather longer term safety and efficacy data.

To date, 254 patients have completed 12 weeks of the extension trial for a total 36 weeks of treatment. The data indicates that there are no clinically or statistically significant changes in serum creatinine or glomerular filtration rate (GFR) over the duration of the trial period.

As anticipated, the improvement in PASI scores remained fairly stable for those patients previously in the mid dose group of the SPIRIT trial. Patients previously in the low dose group have seen an improvement in mean percent change in PASI scores from 42% to 66% after 12 weeks on the mid dose. Patients previously in the high dose group have seen a slight change in PASI scores from 70% to 61%.

"Our optimism regarding the efficacy of ISA247 and lack of renal or any other toxicity seen after 24 weeks of therapy is confirmed in the extension study data to date," stated Dr. Gilles Lauzon, Director of the Division of Dermatology at the University of Alberta.

"I am extremely pleased that the nine month data strongly suggests long term safety of ISA247 in patients suffering from moderate to severe psoriasis," added Dr. Randall Yatscoff, Isotechnika's President & CEO. "The data generated to date continues to support the safety and efficacy profile of ISA247. In addition, the Company reached a significant milestone with ISA247 treatment. Beginning on December 2, 2005, a number of psoriasis patients have received continuous oral treatment of ISA247 for one year. We look forward to receiving data on these patients in the coming months."

Management will host a conference call to provide an overview of the nine month interim safety data this afternoon at 4:15 p.m. EST / 2:15 p.m. MST.
