Brief Summary

Chronic obstructive pulmonary disease (COPD) is a progressive disorder of the lung parenchyma and airways, which is the third-leading cause of death in the USA. Current therapies for COPD are only partially effective and may also have side effects. Although increasing evidence indicates that quercetin supplementation may be beneficial in treating COPD, key methodological issues have not been resolved. The overall objective of this study is to determine the dosage of quercetin supplementation, bioavailability of quercetin, safety, dose-response relationship and appropriate biomarkers which reflect clinical outcomes in patients with COPD that is necessary for conducting large clinical trials in this patient population.

Outcome Measures

Primary Outcomes (1)

  • Participants Who Experienced Safety Concerns, Where Safety Concerns of Quercetin Supplementation is Indicated by Significant Change From Baseline Measures of Tests Indicated Below in Outcome Measure Description

    Note: If values for any of the measures indicated here were found, the participant would be indicated as a participant with a safety concern, and values for that particular measure would be posted specifically, but since none of the participants experienced these outlying values, results of all tests are expressed here as a composite function. PULMONARY FUNCTION TEST: FEV1% of predicted: decline by \>20% from baseline COMPLETE BLOOD COUNTS: WBC (cells)/mm3 : \<2000, Platelets (cells)/mm3: \<25,000, Hemoglobin (g/dL): \<7.0 COMPREHENSIVE METABOLIC PROFILE (study drug related):Sodium (mmol/L): \<125 or \>148, Potassium (mmol/L): \< 3.0 or \> 6.0, Calcium (mmol/L): \<7.4 or \> 11.5, LIVER FUNCTION TESTS INCREASE BY FACTOR: Enzymes ALT, AST, and Alkaline phosphate, Total bilirubin: for any of these a value \>3X upper limit of normal
