Isotechnika's Phase III Psoriasis Trial Achieves Clinical Endpoints
Edmonton, Canada (ots/PRNewswire) - Isotechnika Inc. announced today the unblinded 12 week data for the Company's Canadian Phase III psoriasis trial for its lead immunosuppressive drug, ISA247.
@@start.t1@@ A Summary of the results is as follows:
- The study met all primary and secondary efficacy endpoints determined
at 12 weeks
- Efficacy endpoints were achieved with minimal side effects
- No clinically significant differences in mean serum creatinine and
glomerular filtration rate (GFR) were observed amongst the four
treatment groups at 12 weeks@@end@@
The Canadian Phase III Psoriasis (SPIRIT) trial commenced on December 2, 2004 and included a total of 453 patients with stable moderate to severe plaque psoriasis. 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.
"Our goal was to create a drug with a superior safety and efficacy profile compared to other medications used to treat psoriasis," stated Dr. Randall Yatscoff, Isotechnika's President and COO. "We are pleased to have achieved these goals in the interim data analysis which indicates the presence of a therapeutic window. It is very encouraging to see that our 24 week endpoints were achieved at the 12 week point of the trial."
In the high dose group, 48% of the patients achieved a PASI 75 score and 72% achieved a PASI 50 score. Furthermore, in the mid dose group 24% and 47% of the patients achieved PASI 75 and PASI 50 scores, respectively. Both the PASI 50 and PASI 75 scores were clinically significant (p less than 0.05) versus placebo. The mean percentage reduction in the PASI scores of the high dose group and the mid dose group were 62.5% and 44.0%, respectively.
Incidences of treatment-related adverse events in patients receiving ISA247 were similar to those receiving placebo. Additionally, there were no clinically significant changes noted in any of the parameters monitored including hypertension, cholesterol, triglycerides and infectious complications analyzed for the interim report. The highest mean change in serum creatinine at 12 weeks was 5% above baseline in the high dose (0.4 mg/kg twice daily) group. This mean percentage change is not clinically significant as it is within normal analytical and physiological variation. After 12 weeks of treatment, a total of five patients, (four in the high dose (4%) and one in the mid dose (1%)) were withdrawn from the trial due to a clinically significant effect on kidney function.
"The results with ISA247 indicate that efficacy equals that of the best treatments presently available for severe psoriasis. This study positions ISA247 as a possible first line therapy for severe psoriasis while providing a side-effect profile not different from placebo," states Dr. Gilles Lauzon, Director of the Division of Dermatology at the University of Alberta.
