Isotechnika Inc. Announces Promising Results From Phase I TAFA93 Trials
Edmonton, Alberta (ots/PRNewswire)
- Isotechnika Inc. announced today promising results from its Phase I TAFA93 trials. TAFA93, a pro-drug of rapamycin, is a novel small molecule mTOR inhibitor, which is a class of drugs currently used in the prevention of organ rejection in transplantation. mTOR inhibitors are typically used in combination with calcineurin inhibitors after organ transplant. mTOR inhibitors also have potential use in oncology and in cardiac stent technology.
A TAFA93 Phase Ia single center, randomized, placebo-controlled, Single Ascending Dose (SAD) trial commenced in July, 2004. The results indicated that doses of 0.04, 0.08 and 0.16 mg/kg TAFA93 taken once daily were safe and well tolerated in healthy volunteers. No serious adverse events were reported. The data obtained from the Phase Ia trial was used to ascertain the most appropriate dose levels for the Phase Ib clinical trial.
Earlier this year a Phase Ib, single center, randomized, placebo- controlled, Multiple-Ascending Dose (MAD), double-blind trial was conducted with TAFA93. The primary objective of this study was to assess the tolerability, safety and pharmacokinetics of multiple doses of TAFA93 in healthy volunteers. Thirty six subjects were randomized to receive either placebo or oral doses of TAFA93 (0.04, 0.08 or 0.16 mg/kg once daily) for 13 consecutive days.
Overall, the Phase Ib TAFA93 trial suggested that the drug was very well tolerated. No serious adverse events were reported during the trial. TAFA93 administration in the dose range of 0.04 mg/kg to 0.16 mg/kg resulted in dose-proportional rapamycin pharmacokinetics, following both single and multiple doses with stable and linear pharmacokinetics. In addition, the pharmacokinetic profiles display less peak-to-trough variability due to a modified input of the drug, when compared to historical rapamycin data.
The successful completion of the Phase I TAFA93 trials fulfills one of our commitments to Atrium Medical Corporation ("Atrium") and allows Atrium to continue moving forward with their drug eluting stent technology program.
"Our theory is that having drug concentrations within a therapeutic window for a longer period of time may be beneficial giving immunosuppressive coverage for a more prolonged period of time," stated Dr. Randall Yatscoff, Isotechnika's President and CEO. "These results from these trials are consistent with this theory. This may result in optimized immunosuppressive efficacy and reduced side effects normally associated with this drug class."
