Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

In this pilot study, the investigators will determine the response of the natriuretic peptide (NP) hormone system after a dose of intravenous dexamethasone (a steroid medication). The goal of the proposed project is to generate preliminary data that will be used to develop power calculations, inform cutoff ranges, and inform the timing of the NP response for larger subsequent studies. Aim: To determine the range of distribution and time course of natriuretic peptide (NP) responses to a single dose of dexamethasone IV 4 mg in healthy lean individuals. Hypothesis: Determination of the NP responses (the range and time course of changes in NP levels) to dexamethasone in 10 healthy individuals will inform the time course and frequency of blood sampling in a definitive prospective study, as well as enable investigators to perform a sample size calculation for a definitive prospective study.

Investigators

The overall officials registered on this study. Names that resolve to a findmyKOL profile link to it; the rest are shown as registered.

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
