Prospective Study Comparing Brand and Generic Immunosuppression on Transplant Outcomes, Adherence, & Immune Response
As the patents for brand-name immunosuppressive medications expire, there is increasing
interest in using generic immunosuppressive drugs. However, despite pharmacokinetic studies
showing bioequivalence, questions remain regarding the clinical impact of use of generic
immunosuppression.
The most important immunosuppressive agent in the modern transplant era is arguably
tacrolimus, a calcineurin-inhibitor with a narrow therapeutic index. This study seeks to
answer the question regarding the clinical impact of generic tacrolimus use as measured
primarily by acute rejection, loss of graft function, and patient death through a randomized
trial of 2 parallel groups: Brand tacrolimus only, and Generic A tacrolimus only. Given that
kidney transplantations are the most commonly performed transplants with well-defined
measures of rejection and graft failure, this organs will be studied in a six-center study
designed to accrue the target number of transplant recipients within the one-year study
period.

A prospective, randomized, open-label, multicenter, parallel, observational study to assess
safety and efficacy of 200 kidney transplant recipients comparing brand tacrolimus to generic
tacrolimus over a one year follow up period. All subjects will receive other
immunosuppressive medications including induction therapy (thymoglobulin, basiliximab, or no
induction) and maintenance including mycophenolate mofetil and corticosteroid therapy as
directed by standard-of-care at each center. Their medication information will be recorded in
their study files.
The study population includes recipients of kidney allografts in the first 14 days after
transplantation.
The totals of 7 visits over 12 months period are planned as follows. The blood samples
specified below are for the translational research study labs. Subjects will continue to
receive routine labs as part of their standard of care from their treating physician. These
safety labs are done as part of their stand of care from their treating physician.
If the subject needs more study drug medication before his or her next study visit the
subject will come in to the clinic to get a new supply.
First (Baseline) Visit (up to 14 days after transplant but before the study subject is
discharged from the hospital):
- Subject reviews and signs consent form
- Review of subject's medical history
- Review of subject's current medications
- Review of subject's physical exam including vital signs (blood pressure, temperature,
pulse and respiration rate), height and weight
- Review of any changes in subject's health and any reactions to the study medication will
be recorded
- About 16 cc blood sample (about 3.2 teaspoons of blood) will be collected from the
subject for translational research study laboratory tests
- Randomization of subject
- Subject will receive study drug.
Month 1 Visit:
- Review of subject's current medications
- Review of subject's physical exam including vital signs (blood pressure, temperature,
pulse and respiration rate), height and weight
- Review of any changes in subject's health and any reactions to the study medication will
be recorded
- Subject returns completed dosing diary and receives new dosing diary
- Subject will receive study drug.
Month 2/3 Visit:
- Review of subject's current medications
- Review of subject's physical exam including vital signs (blood pressure, temperature,
pulse and respiration rate), height and weight
- Review of any changes in subject's health and any reactions to the study medication will
be recorded
- Subject returns completed dosing diary and receives unfilled dosing diary
- Subject will receive study drug.
Month 6/9/12 Visit:
- Review of subject's current medications
- Review of subject's physical exam including vital signs (blood pressure, temperature,
pulse and respiration rate), height and weight
- Review of any changes in subject's health and any reactions to the study medication will
be recorded
- Subject returns completed dosing diary and receives unfilled dosing diary
- Subject will receive study drug if applicable.
Adherence will be measured with daily medication diaries and with the coefficient of
variation of tacrolimus in subjects' blood.
