Conditions

Long COVID

Brief summary

The goal of this study is to determine whether a medicine called tirzepatide, also called Zepbound, can reduce symptoms of Long COVID. A randomized control trial will allow us to measure the effect of the treatment by having half of the participants take the medication and half take a placebo that has no medication. Participants will take the medication (or placebo) they are given and complete study surveys for 12 months. All of the study tasks are done remotely from the comfort of a participants home.

Interventions

DRUGTirzepatide

The treatment group will receive the study medication (tirzepatide) for a 12 month period starting with a 2.5mg dose once a week.

DRUGPlacebo

Participants in the control group will receive a placebo instead of active study medication for a 12 month period.

Design outcomes

Primary

MeasureTime frameDescription
Primary Objective 1: Changes in fatigue severity score, measured by Fatigue Severity Scale (FSS)12 monthsThe average difference in Fatigue Severity Scale (minimum score 9, maximum score 63, with higher scores indicating worse fatigue) between treatment and control groups of adults with Long COVID at month 3 or month 12 after study start

Secondary

MeasureTime frameDescription
Secondary Outcome: Changes in overall health, measured by European Quality of Life 5 day, 5 level (EQ-5D-5L) scores12 monthsEQ-5D-5L is a quality of life survey with a minimum score of 5 and a maximum score of 25, with a higher score indicating worse quality of life.
Secondary Outcome: Presence of and changes in post-exertional malaise, a condition that occurs in subsets of Long COVID and IACIs, measured by DePaul Symptom Questionnaire Post Exertional Malaise (DSQ-PEM)12 monthDSQ-PEM evaluates the presence or absence of PEM and myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS)
Secondary Outcome: Changes in functional capacity as measured by Functional Capacity (FUNCAP) survey12 monthsThe 27-question version of FUNCAP has a minimum score of 0 and a maximum score of 162, with a lower score indicating lower functional capacity.
