Endometriosis: Immunomodulation

Status Withdrawn

Clinical Trial Summary

The purpose of this study is to compare the effect of pioglitazone versus no drug on soluble profinflammatory markers in peritoneal fluid of women with endometriosis.

Clinical Trial Description

The overall goal of this proposal is to assess modulation of immune mechanisms in endometriosis. Endometriosis is a common ailment affecting approximately five million reproductive-aged American women. We will test the efficacy of a novel immunomodulatory drug (peroxisome proliferator activated receptor gamma, PPAR-gamma, agonist), pioglitazone, to reduce peritoneal fluid cytokine concentrations in women with endometriosis compared with the non-treated controls (randomized controlled trial). Based on prior studies done by the investigator highlighting the major role of cytokines and the immune system in the genesis or propagation of endometriosis, these experiments could lead to improved translational treatment strategies and a better understanding of endometriosis. Acting through PPAR-gamma, TZDs inhibit proinflammatory cytokines as well as NF-kB, an important nuclear transcription factor for the production of many cytokines. Accordingly, since human endometrial epithelial and stromal cells contain PPAR-gamma, we felt i would be useful to evaluate the influence of a PPAR-gamma ligand, pioglitazone, on the concentration of specific peritoneal fluid cytokines.

Comparison: After the pre-trial screening, eligible subjects with presumed endometriosis and age 18-45 will be consented and randomly assigned to receive either pioglitazone (30 mg, daily)or no drug for 2 weeks. Peritoneal fluid will be collected at the time of surgery and the volume measured. All patients enrolled in the study will have their surgery during the follicular phase of the cycle in order to minimize differences in volume and cytokine concentration due to the cyclical changes. The primary measure will be the peritoneal fluid concentration comparisons of the two groups assessing six different cytokines. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
