Active clinical trials for "Common Cold"

The objective of this study is to evaluate the microbial consortia and the host inflammatory factors present in the nasal passages of patients during upper respiratory symptomology and when healthy using culture and molecular analysis techniques.

An open access study that will define and collect digital measures of coughing in multiple populations and public spaces using various means of audio data collection.

A phase II randomised, placebo-controlled trial to identify the optimal regimen of vitamin D supplementation for rhinovirus protection, determined by host responses to a clinically induced rhinovirus challenge. The primary outcome is rhinovirus titre after inoculation with rhinovirus; secondary outcomes are self-reported respiratory symptom scores, concentrations of cytokines and chemokines sampled from the nasal mucosa, and the transcriptional responses of nasal epithelial cells.
