Study summary

Myfortic (enteric-coated mycophenolate sodium) has been shown to have similar effectiveness to CellCept (mycophenolate mofetil) in preventing rejection in kidney transplant recipients. However, enteric coated mycophenolate sodium has been thought to possibly be associated with fewer gastrointestinal side effects. Mycophenolate mofetil and enteric coated mycophenolate sodium pharmacokinetics (how the drug is absorbed and broken down) have not been well-studied in African American kidney transplant recipients. The investigators are interested in studying enteric coated mycophenolate sodium and mycophenolate mofetil pharmacokinetics and gastrointestinal side effects in African American kidney transplant recipients.

Read the detailed description

African American patients often experience more gastrointestinal (GI) complications after kidney transplant than Caucasian patients. In addition, African American kidney transplant recipients also experience a higher incidence of acute rejection and have worse outcomes compared with all other ethnic groups. Reasons accounting for these differences are not well understood.

In light of the increased risk of GI complications in African American patients, we will compare in a pilot study, different regimens (described below) that we commonly use in our clinical practice in this population. As part of this study, patients will also fill out a GSRS survey at specified time points to help describe gastrointestinal side effects after transplant.

Pharmacokinetic studies (studies looking at how the drugs are absorbed and broken down) for mycophenolate mofetil or enteric coated mycophenolate sodium have largely been performed in Caucasian populations. There is little information available in African-American patients. This is particularly concerning in the face of the worst clinical outcomes observed after transplantation in African American kidney transplant recipients.

Comparisons: Patients will be randomized to one of two groups

  • Group 1: Myfortic (enteric-coated mycophenolate sodium) in combination with Prograf (tacrolimus) or its generic equivalent and corticosteroids
  • Group 2: CellCept (mycophenolate mofetil) or its generic equivalent manufactured by Sandoz in combination with Prograf (tacrolimus) or its generic equivalent and corticosteroids

Since toxicity of mycophenolate mofetil and enteric coated mycophenolate sodium may be influenced by pharmacokinetics (studies that look at how the drugs are absorbed and broken down) of these respective drugs, we will compare the pharmacokinetics of enteric coated mycophenolate sodium and mycophenolate mofetil in a subset of patients. This pharmacokinetic data may have the additional valuable benefit of helping to optimize dosing parameters for mycophenolate mofetil and enteric coated mycophenolate sodium in African American kidney transplant patients in the future.

What researchers measure

Primary outcomes

  1. Gastrointestinal Toxicity Due to Enteric Coated Mycophenolate Sodium or Mycophenolate Mofetil or Its Generic Equivalent Formulation Manufactured by Sandoz

    At 24 weeks, we assessed the number of patients at this timepoint who required permanent dose decrease or discontinuation of either enteric coated mycophenolate sodium or mycophenolate mofetil or its generic equivalent formulation manufactured by Sandoz related to gastrointestinal toxicity.

    Time frame: 6 months

Secondary outcomes

  1. The Incidence of the Requirement of Full Dose Proton Pump Inhibitors in Patients on Enteric Coated Mycophenolate Sodium or Mycophenolate Mofetil or Its Generic Equivalent Manufactured by Sandoz

    If patients were not on any medications from a medication class known as H-2 antagonists, they were started on ranitidine 150 mg orally twice daily after transplant (with dose adjusted for renal function). Patients were excluded if they were on proton pump inhibitor at time of study screening, however some patients required addition of proton pump inhibitor post-study enrollment. If a patient had upper gastrointestinal side effects such as acid reflux unreleived on ranitidine therapy or nausea, they were switched to a proton pump inhibitor.

    Time frame: 6 months

  2. The Incidence of Intolerance (Defined as Transient Dose Reduction or Transient Discontinuation of Enteric Coated Mycophenolate Sodium or Mycophenolate Mofetil or Its Generic Equivalent Manufactured by Sandoz

    The incidence of intolerance was defined as transient dose reduction or transient discontinuation of enteric coated mycophenolate sodium or mycophenolate mofetil or its generic equivalent manufactured by Sandoz meaning doses could subsequently be resumed or increased back to original starting dose, once intolerance resolved.

    Time frame: 6 months

  3. Gastrointestinal Symptom Rating Scale (GSRS) Score Changes From Baseline to 24 Weeks After Transplant in Patients on Enteric Coated Mycophenolate Sodium or Mycophenolate Mofetil or Its Generic Equivalent Manufactured by Sandoz

    The Gastrointestinal Symptom Rating Scale (GSRS) is a 15-item self-administered questionnaire to assess symptoms associated with common gastrointestinal (GI) disorders, and has been validated in renal transplant recipients. It uses a seven-graded Likert scale, where 1 represents the most positive option and 7 the most negative one and the patient grades symptoms based on the past 7 days. A score of ≥ 2 indicates the presence of GI symptoms. Higher values indicate more unfavorable conditions. The questionairre is divided into 5 sub-scales: diarrhea, indigestion, constipation, abdominal pain, and reflux and a mean score is calculated for each dimension. The lowest mean score possible for each dimension is 1 and the highest is 7. Patients completed a GSRS survey at baseline (pre-transplant to two days after transplant), and at weeks 1,4,12 and 24 after transplant.

    Time frame: baseline (pre-transplant to two days after transplant) and at 6 months after transplant.

Statistical analysis
  • Myfortic Comparator Group vs CellCept Comparator Group · Kruskal-Wallis · p = 0.27 (p value represents data for week 4. A p value of less than 0.05 was considered significant.)
  • Myfortic Comparator Group vs CellCept Comparator Group · Kruskal-Wallis · p = 0.23 (p value represents data for week 24. A p value of less than 0.05 was considered significant.)

Adverse events

Collected over 6 months. Non-serious events are listed at a 5% frequency threshold.
