Isotechnika's independent data monitoring committee conducts review of Phase 3 psoriasis trial

    EDMONTON, March 31 /CNW/ - Isotechnika Inc. announced today that an
independent data monitoring committee (DMC) has met and reviewed the interim
data from the ongoing Phase 3 psoriasis (ESSENCE) trial. The review included
24-week data from approximately 50% of the patients enrolled in the trial.
Based on their review of the safety and efficacy data, the DMC has not raised
any concerns that would require a change to the original study design.
    The first patient was enrolled in the ESSENCE trial on December 3, 2006.
On July 20, 2007, the Company completed patient recruitment at 642 patients.
The patient population is composed of 295 patients from Germany, 116 from
Poland and 231 from Canada. The trial is currently being performed at a total
of 50 centers.
    "The role of the DMC is to ensure the safety of the patients
participating in this trial," commented Dr. Foster, Isotechnika's Chairman &
Chief Executive Officer. "While efficacy can be determined as early as 12
weeks, the trial has been designed to remain blinded for the entire 60 week
duration so that longer-term safety data remains unbiased. The result of the
review was as expected and is very encouraging."

    European/Canadian Phase 3 Psoriasis Trial Design
    The ESSENCE trial is being conducted as a randomized, orally
administrated placebo and cyclosporine-controlled study with patients
receiving voclosporin (0.4 mg/kg twice daily), patients receiving cyclosporine
(1.5 mg/kg twice daily) and patients receiving placebo in a 3:1:1 ratio for 24
weeks. Patients enrolled in the placebo group will be converted to the
voclosporin arm following the first 12 weeks of treatment.
    Upon the Company receiving regulatory approval for an extension to this
trial, patients who had not yet finished the 24 week portion of the trial were
given the opportunity to remain on therapy for an additional 36 weeks - making
the total length of treatment 60 weeks for these patients.
    Successful completion of the trial will be determined by the primary
endpoint of superiority in the proportion of patients achieving a score of
"clear" or "almost clear" in the Static Physician's Global Assessment ("SPGA")
score at 12 weeks in the voclosporin treatment group compared to placebo
control. Secondary endpoints include, amongst others, non-inferiority of
voclosporin compared to the cyclosporine control arm in the proportion of
patients achieving a score of "clear" or "almost clear" in the SPGA score at
12 weeks and a 75% reduction in the PASI score.
