Isotechnika Reports Final Results of the PROMISE Trial

Edmonton, Canada (ots/PRNewswire)

Isotechnika Inc.
(TSX:ISA) today announced positive results from the  Phase 2b PROMISE
trial which evaluated the Company's lead drug, voclosporin , in de
novo kidney transplant patients. This trial was designed to
determine the most appropriate dosing strategy for the Phase 3
program in  kidney transplantation.
"PROMISE has shown that the efficacy of voclosporin is
statistically  non-inferior when compared to the market leader,
tacrolimus in all three  dose groups," stated Dr. Robert Foster,
Isotechnika's Chairman & CEO. " While matching tacrolimus in
efficacy, key safety advantages such as a  lower incidence of new
onset diabetes mellitus (NODM) and preservation of  kidney function
were shown. In addition to highlighting these key safety  advantages,
the wide therapeutic window was confirmed. This window will  enable
clinicians to maximize both efficacy and safety, therefore offering
significant clinical benefit compared to the other calcineurin
inhibitors."
Efficacy Results:
The primary efficacy objective of this trial was to demonstrate
non- inferiority in biopsy proven acute rejection (BPAR) in de novo
kidney  transplant patients receiving voclosporin as compared to
tacrolimus at six  months. This objective was achieved and non
inferiority was established for  each of the three voclosporin
treatment groups.
Safety Results:
The safety profile of voclosporin compared to tacrolimus was
evaluated  by multiple assessments including NODM, kidney function,
hypertension,  hyperlipidemia, SAEs, AEs, and laboratory values.
Based on these  assessments no specific safety concerns were raised
and the following key  advantages were noted.
-   A statistically lower incidence of NODM at six months post
         transplantation was observed in the low dose voclosporin group
         compared to the tacrolimus group (1.6% vs. 16.4% respectively).
         Although not statistically different, the incidence of NODM was also
         noted to be lower in the mid dose voclosporin group compared to the
         tacrolimus group (5.7% vs. 16.4%, respectively).
         "The use of voclosporin at the mid dose reduced the risk of
         developing NODM by 65% when compared to tacrolimus in de novo kidney
         transplant patients over six months," stated Dr. Richard Lewanczuk,
         Professor, Division of Endocrinology at the University of Alberta.
         "The reduced risk of developing NODM has highly favorable
         implications from a clinical perspective."
     -   Based on the multiple assessments of kidney function, there were no
         statistically significant differences between the low and mid dose
         voclosporin groups and the tacrolimus group over six months. In
         patients who received a living donor kidney, there was a 7.3%
         improvement in kidney function (iothalamate GFR) in the mid dose
         voclosporin group vs. tacrolimus.
         Dr. Herwig Ulf Meier-Kriesche, Professor of Medicine and Clinical
         Director of Renal Transplant in the Department of Medicine,
         University of Florida added, "When compared to results of other
         calcineurin inhibitors such as tacrolimus or cyclosporin, these are
         very encouraging results."
The final Phase 2b results will be presented at the upcoming
American  Transplant Congress.
North American Phase 2b Kidney Transplant Trial Design
Forty-two centers across North America have been contracted to
perform  the trial, including thirty-eight centers in the United
States and four  centers in Canada. The primary endpoint of the trial
was defined as non- inferiority in biopsy proven acute rejection
(BPAR) episodes in patients  receiving voclosporin for six months as
compared to the tacrolimus control  which is currently the leading
North American transplant drug in this class . Additionally, kidney
function and other laboratory parameters were  monitored throughout
the trial. The use of the other two calcineurin  inhibitors,
cyclosporin and tacrolimus, are often associated with  significant
safety concerns.
A total of 334 de novo (newly transplanted) kidney transplant
patients  were enrolled in the trial. Patients were placed into one
of four separate  treatment groups; three different dose groups of
voclosporin (0.4 mg/kg,  0.6 mg/kg, and 0.8 mg/kg twice daily)
compared with the fourth group, a  tacrolimus control arm (0.05 mg/kg
twice daily). Patients in all four  treatment groups had their doses
adjusted in order to achieve pre-defined  blood levels of either
voclosporin or tacrolimus. All patients received  oral dosing with
the drug (voclosporin or tacrolimus) over a six month  period along
with other standard immunosuppressive therapies used following
transplantation.
About Isotechnika
Edmonton-based Isotechnika Inc. is an international
biopharmaceutical  company focused on the discovery and development
of novel immunosuppressive  therapeutics that are designed to offer
advantages over other currently  available treatments. There is a
significant unmet medical need in the  treatment of both solid organ
transplantation and autoimmune disease. It is  estimated that the
market potential will exceed $4 billion annually in  sales for
calcineurin inhibitors such as voclosporin by 2010.
Voclosporin is a next generation calcineurin inhibitor, which
recently  completed a Phase 2b North American trial for the
prevention of kidney  rejection following transplantation. An
extension to the Phase 2b trial and  a combined Phase 3
European/Canadian trial for the treatment of moderate to  severe
psoriasis are ongoing. Our partner, Lux Biosciences, is currently
conducting three separate Phase 2/3 pivotal trials investigating
voclosporin (referred to as LX211 by Lux) for the treatment of
uveitis.
