Composite Primary Endpoint Outcomes at 1 Year Post Conversion1,2*

Composite primary endpoint outcomes_swtich_Rev_OL.svg

With a primary efficacy endpoint of treatment failure at 1 year, treatment difference for ENVARSUS XR vs Prograf was 0% (95% CI [–4.2%, 4.2%]), well within the 9% prespecified non-inferiority margin.2†

No acute rejection episodes in first 30 days post conversion3

Renal function was maintained

Diarrhea 14% 9%
Blood creatinine increased 12% 9%
Urinary tract infection 9% 14%

There were no significant differences between the ENVARSUS XR and Prograf groups in predefined potentially clinically significant laboratory measures incidence of new onset diabetes mellitus, opportunistic infection, or malignancies.1

  • Study Design: The efficacy and safety of ENVARSUS XR was evaluated in an internationally conducted multicenter (n=33 US, n=14 Europe) open-label study of stable adult kidney transplant recipients 3 months to 5 years post-transplant (N=326) converted from Prograf to ENVARSUS XR. According to standard of care, concomitant therapy with mycophenolate mofetil (MMF), azathioprine (AZA), and corticosteroids was permitted but not required. Patients were converted to ENVARSUS XR at a reduced dose or continued Prograf at the same dose.2
  • Treatment failure at 12 months was a composite endpoint of death, graft failure, BPAR, and patients lost to follow-up.
  • Study was not designed to support comparative claims of ENVARSUS XR compared to tacrolimus immediate-release for the adverse reactions reported in this table.

BPAR, biopsy-proven acute rejection; CI, confidence interval; eGFR, estimated glomerular filtration rate
