Isotechnika Announces Initial Data From Phase IIb Kidney Transplant Trial
Edmonton, Canada, November 16 (ots/PRNewswire)
- Transplant Data Presented at the American Society of Nephrology Conference
Isotechnika Inc. today announced results from initial data for its Phase IIb kidney transplant trial of the Company's lead immunosuppressive drug, ISA247.
To date, 133 patients have been enrolled in the trial. Based on an early review of the unaudited data, the Company has observed a similar incidence of rejection episodes between the low (0.4 mg/kg twice daily) and mid (0.6 mg/kg twice daily) ISA247 dosing groups as in the tacrolimus control arm. To date, there have been no rejections in the high (0.8 mg/kg twice daily) ISA247 dose group. When all three of the ISA247 dosing groups are combined, there is an 8% rate of acute rejection in the ISA247 groups compared to a 14% rate in the tacrolimus group, which is being dosed according to clinical practice.
As part of the trial, kidney function is being measured by Glomerular Filtration Rate (GFR) on an ongoing basis. Based on the data generated to date, very good kidney function has been observed in all of the ISA247 dosing groups. Within the first month post-transplant, kidney function showed improvement across all ISA247 dosing groups similar to that observed in the tacrolimus group. Additionally, there have been no clinically significant differences noted in cholesterol and triglycerides or other laboratory parameters examined to date in patients receiving ISA247.
"We are pleased that all three ISA247 doses are showing good efficacy while maintaining very good kidney function," stated Dr. Randall Yatscoff, President & CEO of Isotechnika. "Furthermore, ISA247 continues to demonstrate a strong Pharmacokinetics and Pharmacodynamics (PK/PD) correlation which should facilitate ease of dosing to achieve desired targeted drug concentrations in blood."
The Phase IIb kidney transplant data is being presented today at the American Society of Nephrology Conference in San Diego. The poster entitled "ISA247: A Novel Calcineurin Inhibitor (CNI) A Promising Safety Profile With Enhanced Efficacy" will be presented by Dr. Robert Gaston, one of the principal investigators involved in the Phase IIb trial. All interested parties will be able to access a copy of the scientific poster in the Investor Relations section of the web site.
The management team will provide an update on the current status of the Phase IIb kidney transplant trial via a live web cast this morning at 9:00 a.m. ET/7:00 a.m. MT. All interested parties will be able to access the live event through the Company's corporate web site at www.isotechnika.com.
Trial Design
Forty-two centres across North America have been contracted to perform the trial, including thirty-seven centres in the United States and five centres in Canada. The primary endpoint of the trial is defined as non-inferiority in biopsy proven acute rejection (BPAR) episodes in patients receiving ISA247 for six months as compared to the tacrolimus control which is currently the North American leading transplant drug in this class. Additionally, kidney function and other laboratory parameters will be monitored for the duration of the trial. The overall goal of the trial is to find the most appropriate dose that will result in efficacy (lack of acute rejection) with minimal side effects that are typically seen with other calcineurin inhibitors such as cyclosporine and tacrolimus.
A total of 332 de novo (newly transplanted) kidney transplant patients will be enrolled in this trial. Patients will be placed into one of four separate treatment groups; three different dose groups of ISA247 (0.4 mg/kg, 0.6 mg/kg, and 0.8 mg/kg twice daily) compared with the fourth group, a tacrolimus (0.05 mg/kg twice daily) control arm. Patients in all four treatment groups will have their doses adjusted in order to achieve pre-defined blood levels of either ISA247 or tacrolimus. All patients will receive oral treatment of drug (ISA247 or tacrolimus) over a six month period along with other standard immunosuppressive therapies used following transplantation.
