Correlation of Mesalamine Pharmacokinetics With Local Availability
May 2, 2017 updated by: Duxin Sun, University of Michigan
This study is designed to provide data to the FDA correlating pharmacokinetics with local availability of medications within the gastrointestinal tract.
This study will support the establishment of scientifically based standards for evaluating drugs which act locally within the gastrointestinal tract.
Specific objectives of this study are to: (1) quantify how the plasma concentrations of mesalamine, an agent used to treat inflammatory bowel disease, are correlated with the concentrations in gastrointestinal fluids; and (2) improve the physiologically based models for drug absorption from the intestine.
Information from this study in concert with in vitro dissolution data will be used to evaluate in vivo-in vitro correlation (IVIVC) for concentrations in plasma and intestinal lumen and dissolution of mesalamine products.
Study Overview
Status
Completed
Detailed Description
This study evaluated the pharmacokinetics of mesalamine and its major metabolite of mesalamine known as N-acetyl-mesalamine in plasma.
Mesalamine is available in different formulations that control the rate at which they are released in the gastrointestinal tract.
Three formulations of mesalamine, Pentasa, Apriso, and Lialda, were studied in the crossover phase, while an oral solution formulation of mesalamine was studied in the single-arm phase.
Each subject participated in a crossover phase study with one of the three formulations assigned at random using block randomization.
Then the subject entered the single-arm phase study.
After participation in one crossover phase study and one single-arm phase study, the subject could opt to participate in crossover phase studies using the other formulations also chosen at random until all three formulations were studied.
The single-arm phase study was not repeated on returning subjects who participated in more than one crossover phase study.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The AUC of Mesalamine in Plasma
Time Frame: 0 hours pre-dose and up to 96 hours post-dose
|
The AUC is the area under the concentration-time curve from time 0 to last time point.
The data are organized by the different drug formulations of mesalamine, which include Pentasa (0 to 72 hours), Apriso (0 to 72 hours), Lialda (0 to 96 hours), and Delzicol (0 to 24 hours).
The AUC is measured in units of nanomoles of mesalamine per liter of plasma (nM) multiplied by time in hours (nM*h).
The AUC results are reported over the time-period because this provides a more meaningful comparison of potential differences in the bioequivalence of formulations.
|
0 hours pre-dose and up to 96 hours post-dose
|
The AUC of Metabolite (N-acetyl-mesalamine) in Plasma
Time Frame: 0 hours pre-dose and up to 96 hours post-dose

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The AUC of Mesalamine in Distal Jejunum
Time Frame: 0 hours pre-dose and up to 7 hours post-dose
|
The AUC is the area under the concentration-time curve from time 0 to 7 hours.
The data are organized by the different drug formulations of mesalamine, which include Pentasa, Apriso, and Lialda.
The AUC is measured in units of micromoles of mesalamine per liter of plasma (µM) multiplied by time in hours (µM*h).The AUC results are reported over the time-period because this provides a more meaningful comparison of potential differences in the bioequivalence of formulations.
The solution formulation (Delzicol) was not administered in this portion of the study.
Therefore no results pertaining to the solution formulation are included in this outcome measure.
