A 1-year Comparison of Generic Tacrolimus (Tacni) and Prograf in Renal Transplant Patients - a Retrospective Matched Pair Analysis

This is a retrospective analysis of two different cohorts of patients that has undergone renal transplantation. This is a matched pair analysis of 100 patients treated with generic tacrolimus that will be compared with 100 matched controls treated with Prograf. Data will be obtained from patients' charts, from the Swedish National Kidney Registry and from a local registry at Transplantationscentrum. Patients included in the study are patients receiving a first single kidney transplant from a deceased or a living donor, treated with Prograf or Tacni and transplanted between transplanted January 2012 and August 2014. The 1-year-outcome of patients following renal transplantation, including BPAR, serious adverse effects and graft survival will be analysed.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

It is a retrospective analysis of two different cohorts of patients that have undergone renal transplantation at Transplanationscentrum in Gothenburg, Sweden. Approximately 100 patients treated with generic tacrolimus will be compared with 100 matched controls. The controls will be selected among 200 patients that are treated with Prograf. The matching will be based upon living/deceased, age of the donor, age of the patient and number of previous transplantations.

Description

Inclusion Criteria:

  • Patients receiving a first single kidney transplant from a deceased or a living donor.
  • Patients treated with Prograf or or generic tacrolimus
  • Patients transplanted between 1 October 2012 and 1 August 2014

Exclusion Criteria:

  • Multi-organ transplants
  • Re-transplantations

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Biopsy-proven acute rejection (BPAR)
Time Frame: 1 year
1 year
Graft loss
Time Frame: 1 year
1 year
Death
Time Frame: 1 year
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Compare the following parameters in the two groups • Graft survival at 6 and 12 months • BPAR at 6 and 12 months • Calculated GFR at 12 months
Time Frame: 6 months, and 1 year
6 months, and 1 year
Compare serious adverse events at 12 months in the two groups
Time Frame: 1 year

Compare the the cost of admissions for rejection treatment in the two groups

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2015

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
