Pilot Study of Aprepitant Effect on Aldosterone Secretion in Diabetic

Status Recruiting

Clinical Trial Summary

Aldosterone regulation is mediated by hormonal control, and nervous control. Autonomic nervous system action could be mediated by neuropeptides in the adrenal gland. Therefore, in pathological conditions and especially in diabetes, low-renin hypertension with normal or high plasma aldosterone could be caused by sympathetic nervous system hypertonia.

Data from the literature and previous in vitro research conducted in the investigators' laboratory (INSERM U982, University of Rouen) suggest that adrenal corticosteroid secretion might be controlled by sympathetic nervous system. This neurocrine regulation of corticosteroid secretion involves locally released neuropeptides. Among them, substance P is able to stimulate aldosterone and cortisol production via NK1 receptors. A previous clinical trial conducted at the University Hospital of Rouen, APHOS (NCT00977223) studied the effects of a NK1 receptor antagonist, aprepitant, on adrenocortical secretions in healthy volunteers.

The aim of the present study is to investigate the effects of a NK1 receptor antagonist, aprepitant, on adrenocortical secretions in volunteers with diabetes associated with low-renin hypertension. Aprepitant is a drug already available for the treatment of nausea induced by chemotherapy.

In the present phase II trial, plasma aldosterone and cortisol levels will be measured under treatment with aprepitant versus placebo, in both basal conditions and after activation of the adrenocortical function by upright posture. All volunteers will be given the two substances (aprepitant and placebo) in a random order during two 14 day-periods separated by a 21 day-wash-out.

This study should allow to determine the role of substance P in the control of corticosteroid production in human with diabetes, associated with a low-renin hypertension.

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.
