Phase 2
Completed
Conditions

Long Term Covid19
Interventions
Drug: Placebo
Registration Number
NCT04960215
Lead Sponsor
Aarhus University Hospital
Brief Summary

This study is a randomized, placebo-controlled, double-blinded, cross-over designed clinical trial investigating the effect of high-dose Coenzyme Q10 treatment in subjects with persisting symptoms more than 12 weeks af SARS-CoV-2 infection, Long Term COVID-19 (LTC).

Detailed Description

The aim is to investigate the effect of high-dose Coenzyme Q10 on number and severity of self-reported symptoms in patients with Long Term COVID-19.

The study will be conducted at the Department of Infectious Diseases, Aarhus University Hospital in the LTC Outpatient Clinic. 120 study participants will be randomized 1:1 to receive placebo or CoQ10 in a dose of 500mg/day for 6 weeks. After a wash-out period of 4 weeks, participants are allocated to the opposite treatment for 6 weeks. The EQ-5D-5L and an LTC-specific questionnaire are completed at baseline and after 6,10,16, and 20 weeks. At each of 5 visits blood samples will be collected from the participants for immunological investigations and assessment of cellular metabolism.

NameTimeMethod
Effect of Coenzyme Q10 treatment in Long Term COVID-19 on number of self-reported symptoms of LTC measured by EQ-5D-5L questionnaire.Changes from baseline questionnaire response to questionnaire response after 6 weeks of treatment

Number of self-reported symptoms measured by EQ-5D-5L questionnaire.

Effect of Coenzyme Q10 treatment in Long Term COVID-19 on severity (symptoms score) of self-reported symptoms of LTC measured by EQ-5D-5L questionnaire.Changes from baseline questionnaire response to questionnaire response after 6 weeks of treatment

Severity by symptom score of self-reported symptoms measured by ED-5Q-5L questionnaire. The questionnaire consist of 5 questions with a graduation of 0-4, thus maximum number of points is 20 implying a high number of severe symptoms.

Effect of Coenzyme Q10 treatment in Long Term COVID-19 on number of self-reported symptoms of LTC measured by Long Term COVID-specific questionnaire.Changes from baseline questionnaire response to questionnaire response after 6 weeks of treatment

Number of self-reported symptoms measured by Long Term COVID-specific questionnaire.

Effect of Coenzyme Q10 treatment in Long Term COVID-19 on severity (symptoms score) of self-reported symptoms of LTC measured by Long Term COVID-specific questionnaire.Changes from baseline questionnaire response to questionnaire response after 6 weeks of treatment
