Myfortic, Prograf, and Corticosteroids in de Novo Liver Transplantation

May 11, 2018 updated by: R. Mark Ghobrial, MD

An Open-label Study of the Pharmacokinetics of Mycophenolic Acid as Myfortic (Enteric-coated Mycophenolate Sodium) When Used in Combination With Prograf (Tacrolimus) and Corticosteroids in Patients Undergoing de Novo Liver Transplantation

The purpose of this study is to gather information regarding the use of Myfortic, Prograf, and corticosteroids in new liver transplant recipients. These three medicines help to prevent the body from rejecting the transplanted liver. The information the investigators are obtaining is data relating to the process of Myfortic absorption by the body, its distribution in the body, the breakdown of Myfortic in the body, and its elimination from the body. This absorption, distribution, breakdown, and elimination is called pharmacokinetics.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

Myfortic is approved for use in kidney transplant recipients, and has been prescribed by doctors for liver transplant recipients. No study has been reported to date evaluating the pharmacokinetics of Myfortic in new liver transplant recipients who also take Prograf and corticosteroids. During this six month study, a series of blood samples will be obtained after subjects take Myfortic, Prograf, and corticosteroids.

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

Probability Sample

Study Population

Patients with end stage liver disease who are receiving a liver transplant at The Methodist Hospital in Houston, Texas and who satify the inclusion/exclusion criteria will be considered for the study.

Description

Inclusion Criteria:

  • Adults > or equal to age 18 years
  • Planned to receive tacrolimus and corticosteroid therapy posttransplant
  • Serum creatinine at transplant < or equal to 2.5mg/dL
  • UCSF tumor staging < 8cm total
  • Females of childbearing potential must have a negative serum pregnancy test within 7 days prior to the baseline visit and are required to practice a reliable method of contraception for the duration of the study and for no fewer than 6 weeks after completing the study.
  • Signed informed consent form prior to any research assessment

Exclusion Criteria:

  • Induction therapy
  • Requiring dialysis at the time of transplant
  • Organ transplant other than liver
  • Pregnant or nursing females
  • Women of childbearing potential not practicing reliable methods of contraception. Reliable methods for contraception include surgical sterilization (hysterectomy, bilateral tubal ligation), double-barrier method (such as condom and diaphragm). To be considered as post-menopausal and not of childbearing potential, female subjects must have experienced 12 consecutive months of amenorrhea.
  • Require any medications that interfere with metabolism of Myfortic (other than corticosteroids)
  • Have a known hypersensitivity to mycophenolate sodium, mycophenolic acid, mycophenolate mofetil, or any of its excipients
  • Participation in a study of investigational drug in the previous 30 days or 5 half-lives of the investigational drug

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
Measure Description
Time Frame
Pharmacokinetic parameters
Time Frame: Twelve hour pharmacokinetics at one week, one month, and six months post transplant
Pharmacokinetic time points will be obtained at 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 8, and 12 hours post dose. The exposure (area under the concentration-time curve, AUC μg·h/mL, Cmax ng/mL, and Tmax, hours) of MPA and MPAG will be calculated using non-compartmental analysis.
Twelve hour pharmacokinetics at one week, one month, and six months post transplant

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
Measure Description
Time Frame
Safety and tolerability
Time Frame: 1 week, 1 month, 6 months
MPA exposure will be assessed at one week, 1 month, and 6 months. Kidney function (using MDRD and Cockcroft-Gault) will be compared with PK parameters and graft survival recorded. Adverse events will be recorded.
1 week, 1 month, 6 months
