About this study

Official title: 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 phases: 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.

The study has now been branched off into 2 phases. Phase 1: consists of randomization of patients onto brand and generic tacrolimus. This was completed once 40 brand patients were enrolled. Phase 2: consists of patients being enrolled only on generic tacrolimus (standard of care from subject's insurance). This will be completed once there is a total of 160 generic participants. 200 participants total in the study.

Read the detailed description

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 you are discharged from the hospital):

  • Review and sign this consent form
  • Review of your medical history
  • Review of your current medications
  • Review of your physical exam including vital signs (blood pressure, temperature, pulse and respiration rate), height and weight
  • Review of clinical labs
  • You will receive your study drug if you are in Part 1 of the study.

If you are a woman of child bearing potential, a pregnancy test will be completed prior to the start of the study. If you are pregnant, you cannot participate in this research study. You also cannot participate in this study if you are currently breastfeeding. You must use a medically acceptable method of birth control during the 1-year study period and for 6 weeks after the last dose of study medication.

It is possible that after the study doctor reviews your medical history and test results, he or she may tell you that you do not qualify to be in the study. If you do not qualify for the study, the doctor will tell you the reason(s) why. If you cannot be in this research study, you will not lose any medical benefits, you can still participate in other studies, and you can still receive the standard treatment prescribed by your physician.

After the Baseline Visit, you will have 6 additional study visits. These will be scheduled for 1, 2, 3, 6, 9, and 12 months after your transplant surgery. The following will occur at each visit:

Month 1, 2, 3, 6, and 9 Visits:

  • Review of your current medications
  • Review of your physical exam including vital signs (blood pressure, temperature, pulse and respiration rate), height and weight
  • Review of any changes in your health and any reactions to the study medication will be recorded
  • Review of your routine standard of care lab results
  • Return completed dosing diary and receive new dosing diary
  • You will receive your study drug if you are in Part 1 of the study

Month 12 Visit (End of Study Visit):

  • Review of your current medications
  • Review of any changes in your health and any reactions to the study medication will be recorded
  • Review of your routine standard of care lab result
  • Return your final completed dosing diary
  • Return any study drug remaining in your possession to the study team if you are in Part 1 of the study

If you are Part 1 and require more study medication before your next study visit, you will come in to the clinic to get a new supply. If you are participating in Part 2, you will obtain more study drug from your local pharmacy.

You will continue having your routine blood and urine collections to monitor your kidney function as part of your standard of care treatment at UCLA, UCSD, UCI, and UCD. The schedule for these routine blood and urine collections will depend on your condition and will be at your treating physician's discretion.

Adherence will be measured with daily medication diaries and with the coefficient of variation of tacrolimus in subjects' blood.

Acute rejection was defined as biopsy-proven rejection according to Banff 2007 criteria.

  8. Quality of Life With Medication Regimen

    Measured: post-transplant

  9. Satisfaction With Medication Regimen

A Phase 4 study testing Prograf and Tacrolimus in people with Renal Transplant Rejection, run by University of California, Los Angeles at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Apr 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to First Occurrence of Acute Rejection, Failure, Death (time frame: 1 year post-transplant). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02866682, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Apr 2023.
