NCT05463393

Brief Summary

It has been well documented that coronavirus COVID-19 disease is associated with massive inflammatory response and cytokine storm. Several medications have been used to ameliorate COVID-19-related inflammation. Xanthohumol, a natural medication extracted from hop cones, possesses strong anti-inflammatory properties and can reduce the severity of inflammatory response. The aim of this study is to analyze the effect of Xanthohumol on clinical course, inflammatory response and outcome in patients admitted to the ICU due to COVID-related acute respiratory failure with an oxygenation index (PaO2/FiO2) less than 150.

Conditions

Outcome Measures

Primary Outcomes (2)

  • Xanthohumol reduces coronavirus-induced inflammatory response

    Xanthohumol possesses strong anti-inflammatory properties. It can reduce the production and secretion of pro-inflammatory cytokines. Additionally, it inhibits inflammatory-induced endothelial dysregulation and exerting antiangiogenic and anti-inflammatory effects.

    one week after regular supplementation

  • Xanthohumol improves clinical course in critically ill COVID-19 patients

    Reduction the severity of inflammatory response should affect clinical course. Strong anti-inflammatory treatment can reduce a risk of poor outcome.

    28 days mortality

Study Arms (2)

Group Xn

EXPERIMENTAL

Patients who received extract from Humulus lupus L rich in Xanthohumol (Hop-RXn™, BioActive-Tech Ltd, Lublin, Poland; http://xanthohumol.com.pl/) as an adjuvant therapy. Based on pharmacokinetics and bioactivity, Xn was administered enterally three times a day every 8 hours at a dose of 1.5 mg/kg body weight (4.5 mg/kg body weight/day) for 7 days. The first dose of Xn was administered within 4 hours after admission to the ICU.

Group C

PLACEBO COMPARATOR

Patients who received 0.9% NaCl at the oral volume 1 mL (similar to Xn volume) three times a day every 8 hours. The first dose of Xn was administered within 4 hours after admission to the ICU.
