Pharmacokinetic studies
Astcoff PK comparison study
(Tremblay et al. 2015) 1
- Study of patients receiving Prograf for one week, then either one week of Envarsus® and one week of Advagraf, or vice versa
- Envarsus® PK parameters differed significantly from Advagraf and Prograf, when normalised to Prograf AUC
- Prograf to Envarsus® conversion required TDD adjustment of -30%; Advagraf to Envarsus® required TDD reduction of -36%
- The SPC states that patients converting from Prograf or Advagraf to Envarsus® should be converted at 1:0.7mg:mg2
ASERTAA PK in black, stable kidney
patients (Trofe-Clark et al. 2015) 3
- PK study of African-American patients converted from Prograf to Envarsus
- Envarsus® PK parameters were less affected by CYP3A5 genotype than IR-tacrolimus
- Envarsus® achieved similar exposure across all genotypes at a reduced dose vs.IR-tacrolimus
