Isotechnika's Phase III Psoriasis Spirit Trial Achieves Safety and Efficacy Endpoints

Edmonton, Canada, November 7 (ots/PRNewswire)

Isotechnika Inc.
(TSX: ISA) announced today the unaudited 24 week data  for the
Company's Canadian Phase III psoriasis trial for its lead
immunosuppressive drug, ISA247.
A summary of the results is as follows:
  • All primary and secondary efficacy endpoints were achieved at 24 weeks
  • Efficacy endpoints were achieved with minimal side effects
  • In the mid- and low-dose groups, continued improvement in PASI scores were observed from 12 to 24 weeks
  • No clinically significant differences in mean serum creatinine and glomerular filtration rate (GFR) were observed amongst the four treatment groups at 24 weeks
"We are extremely pleased to have met our endpoints and achieved a
dose that demonstrates a continual increase in efficacy with minimal
effect on renal function," stated Dr. Randall Yatscoff, Isotechnika's
President & CEO. "Again, this positions us well for future clinical
trials with ISA247. This data supports that ISA247, at therapeutic
doses, is efficacious with minimal side effects."
The overall decrease in PASI scores at 24 weeks for the low (0.2
mg/kg twice daily), mid (0.3 mg/kg twice daily) and high (0.4 mg/kg
twice daily) dose groups were 41%, 55% and 70%, respectively. For the
placebo patients that converted to the mid dose group at 12 weeks the
overall decrease in PASI score was 62%. The PASI 50 scores at 24
weeks for the mid (0.3 mg/kg twice daily) and high (0.4 mg/kg twice
daily) dose groups were 56% and 70%, respectively. PASI 75 scores for
the mid and high dose groups were 26% and 49% at 24 weeks. Patients
treated in the mid dose group and low dose group (0.2 mg/kg twice
daily) experienced a continual increase in efficacy over the 24 week
period with minimal effect on renal function. Both the PASI 50 and
PASI 75 scores were statistically significant (p less than 0.05)
versus placebo. In all dose groups, PASI scores exhibited good
efficacy.
Following 24 weeks of treatment, there were no clinically
significant changes noted in the following parameters; hypertension,
cholesterol, triglycerides and infectious complications which is
consistent with the previously released interim report. Additionally,
the incidence of treatment-related adverse events in patients
receiving ISA247 was not different to those receiving placebo.
The mean decrease in glomerular filtration rate at 24 weeks in the
low, mid and high dose groups was 3.0%, 2.8%, and 6.0%, respectively.
This mean percentage change is not clinically significant as it is
within normal analytical and physiological variation. There were no
progressive changes in renal function from 12 to 24 weeks in all dose
groups. Of the 451 patients enrolled in the trial a total of 7
patients, (six in the high dose (7%) and one in the mid dose (1%))
experienced two consecutive greater than 30% decreases in glomerular
filtration rate. Patients originally receiving placebo that were
subsequently crossed over to the mid-dose group at 12 weeks showed no
change in kidney function.
Dr. Robert Bissonnette, a principal investigator involved in the
Phase III SPIRIT trial stated, "Results from patients treated with
ISA247 for 24 weeks confirm its safety and efficacy profile in the
treatment of psoriasis. These results suggest that ISA247 could
become one of our first line systemic treatments for moderate to
severe psoriasis."
Management will provide an overview of the unblinded Phase III
data this morning at 8:00 a.m. EST/6:00 a.m. MST. All Interested

The Canadian Phase III Psoriasis (SPIRIT) trial commenced on
December 2, 2004. The trial was conducted at 32 sites over a 24 week
period using orally administered ISA247 in psoriatic patients. This
randomized, double-blind trial examined the efficacy of three dosing
groups of ISA247 (0.2 mg/kg, 0.3 mg/kg and 0.4 mg/kg) administered
twice daily compared to placebo with equal numbers of patients
assigned to each of the four treatment groups. The 24 week results
outlined below are based on a total of 451 patients.
