About this study

The objective of this study is to compare the safety and efficacy of Myfortic with CellCept in liver transplant patients. Myfortic and CellCept are both immunosuppressive (anti-rejection) drugs. CellCept is commonly used after liver transplantation but gastrointestinal (GI) side effects are very common, sometimes necessitating in its discontinuation. Myfortic is a new drug similar to CellCept, except it is enteric-coated. Our hypothesis is that Myfortic has less GI side effects than CellCept and also has comparable effectiveness to CellCept.

Read the detailed description

This is a prospective, randomized, double-blinded, single center, safety and efficacy study comparing Myfortic with CellCept used after liver transplantation. Patients with biopsy-proven acute cellular rejection, renal insufficiency (i.e. acute or chronic renal failure requiring hemodialysis or patients with creatinine clearance < 50 ml/min), or calcineurin inhibitor-induced neurotoxicity (defined as the presence of neurologic symptoms such as tremors, altered mental status, seizures, etc) will be randomized to start on either Myfortic (720 mg po bid) or CellCept (1 gm po bid). In those patients with calcineurin-induced neurotoxicity or nephrotoxicity, tacrolimus or cyclosporine doses will also be reduced to maintain serum trough levels of 4-8 mg/dl or 100-200 mg/dl, respectively.

Comparison: Thirty patients will be enrolled and randomized in this two-armed, double-blinded study- half of the patients will receive Myfortic and the other half, CellCept.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. GI Side Effects as Assessed by Gastro Intestinal Symptoms Rating Scale (GSRS) of Enteric-coated Mycophenolate Sodium vs Mycophenolate Mofetil

    The GSRS contains 15 items, each rated on a seven-point Likert scale from no discomfort to very severe discomfort. Based on a factor analysis, the 15 GSRS items break down into the following five scale: abdominal pain syndrome ( abdominal pain, hunger pains, and nausea); reflux syndrome (heartburn and acid regurgitation), diarrhea syndrome (diarrhea, loose stools and urgent need for defecation), indigestion syndrome (borborygmus, abdominal distension, eructation and increased flatus) and constipation syndrome (constipation, hard stools, and feeling of incomplete evacuation).

    The GSRS is a disease-specific instrument of 15 items combined into five symptom clusters depicting Reflux, Abdominal pain, Indigestion, Diarrhea, and Constipation. The GSRS has a seven-point graded Likert-type scale where 1 represents absence of troublesome symptoms and 7 represents very troublesome symptoms. The total GSRS range of scores is 15 to 105 with higher scores meaning the worst of symptoms.

    Measured: screening, 2, 6 and 12 weeks

  2. GI Side Effects as Assessed by Gastro Intestinal Symptoms Rating Scale (GSRS) of Enteric-coated Mycophenolate Sodium vs Mycophenolate Mofetil (Abdominal Pain Subscale)

    The GSRS contains 15 items, each rated on a seven-point Likert scale from no discomfort to very severe discomfort. Based on a factor analysis, the 15 GSRS items break down into the following five scale: abdominal pain syndrome ( abdominal pain, hunger pains, and nausea); reflux syndrome (heartburn and acid regurgitation), diarrhea syndrome (diarrhea, loose stools and urgent need for defecation), indigestion syndrome (borborygmus, abdominal distension, eructation and increased flatus) and constipation syndrome (constipation, hard stools, and feeling of incomplete evacuation).

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?

GI Side Effects as Assessed by Gastro Intestinal Symptoms Rating Scale (GSRS) of Enteric-coated Mycophenolate Sodium vs Mycophenolate Mofetil (time frame: screening, 2, 6 and 12 weeks). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Mar 2017.
