ASTCOFF is the first pharmacokinetic study to compare all three of these branded formulations of tacrolimus and is a two-sequence, three-period crossover study, designed to compare the steady-state PK profiles of Envarsus XR tablets (Veloxis Pharmaceuticals Inc., New Jersey, USA), Astagraf XL (Astellas Pharma US, Inc., Northbrook, IL) capsules administered once-daily and Prograf capsules (Astellas Pharma US, Inc., Northbrook, IL) administered twice-daily in stable renal transplant patients. Patients were dosed with each drug for seven days and blood samples were obtained over 24 hours to obtain pharmacokinetic data.
This study confirmed previously published data for Envarsus and showed greater bioavailability (p<0.0001) and a flatter PK profile characterized by lower peak-to-trough fluctuation (p<0.001) and delayed time to peak concentrations of 6 hrs (p=<0.001) compared to both Prograf and Astagraf. At equivalent exposure, Envarsus achieves at least a 30% dose reduction requirement and a substantively lower peak blood concentration (p=<0.005) compared to the two comparator products.
This novel scientifically rigorous study design implemented by Dr. Simon Tremblay and our team demonstrates that there are potentially clinically meaningful differences between tacrolimus formulations and provides results to transplant clinicians that can be directly applied to patient management.” said Rita Alloway, PharmD, Research Professor of Medicine, University of Cincinnati Medical Center.
“The results from ASTCOFF provide additional evidence of the differentiated PK profile of Envarsus XR and will provide further guidance on how best patients can be switched to Envarsus,” said William Polvino, M.D., chief executive officer of Veloxis. “We look forward to providing Envarsus XR as an option to transplant patients in the near future.”
