Welcome to the Long COVID Treatment Trial-Tirzepatide (LoCITT-T)

Join a fully remote clinical research study for Long COVID (U.S. residents only)

The first intervention we are studying is tirzepatide, also known as Zepbound, a GLP-1 inhibitor that has shown promise in treating many illnesses. We aim to add other interventions as funding becomes available.

The Long COVID Treatment Trial-Tirzepatide (LoCITT-T) is investigating the efficacy of repurposing this drug to treat Long COVID. This study will analyze if tirzepatide can help reduce symptoms in particular by reducing inflammation, primarily neuroinflammation. Secondary benefits may result from improvements in hyperglycemia, blood pressure, weight, and oxidative stress. In addition to pharmaceutical therapy, wrist-worn activity trackers will be used to collect longitudinal real-world health metrics and aid in determining if pacing energy expenditures in combination with the study drug can improve symptom frequency and severity. Smart scales will be distributed to monitor weight fluctuations and provide body composition feedback to participants.

Help Advance Long COVID Research

We are enrolling up to 1,000 participants in LoCITT-T. Reserve your spot today! (U.S. residents only.)

How Does It Work?

1

Eligibility Screening

Take a survey to see if you are eligible to participate.
2

Randomization

Eligible participants are randomly assigned to one of two groups:

– Treatment Group: Receives tirzepatide
– Placebo Group: Receives placebo

Both groups are equally important. Placebo participants help us understand if the study drug is truly working by giving us a baseline comparison. At the end of the trial, we will unblind participants to let them know which group you were in.

How do I dispose of my used syringe?

Put your used needle and syringe in an FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and syringes in your household trash.

If you do not have an FDA-cleared sharps disposal container, you may use a household container that is:

  • made of a heavy-duty plastic,
  • can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out,
  • upright and stable during use,
  • leak-resistant, and
  • properly labeled to warn of hazardous waste inside the container.

When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and syringes. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA’s website at: http://www.fda.gov/safesharpsdisposal

Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this. Do not recycle your used sharps disposal container.

Blood Sample Collection

What if I’m not interested in donating blood samples?

When enrolling we will ask you if you’re willing to donate blood samples. If you are selected to be in the group that donates blood samples, you may choose to not participate in this portion of the study. If you choose to not participate in the blood sample portion, you may continue to participate in the overall study. 

How many samples will I be asked to collect, and when?

If selected to be in the group that donates blood, you will be asked to collect three samples at three different time points for a total of nine collections over the course of the study. You will be prompted to collect the samples before starting the study drug, six months into the study, and again at twelve months.  

Blood samples should only be collected Monday through Thursday and need to be shipped on the same day you collect. Please check the last UPS Air Pickup Time for your local UPS store here before completing your collections.

How will the blood samples be collected?

You will collect your blood samples using an at home blood collection device called the TAP Micro Select. We will send you all the materials you need to complete the collection along with written instructions and a video guide.

My blood collection kit is missing materials. What should I do?

Please report the missing item(s) through the MyDataHelpsTM app. A study coordinator will follow-up. 

If you’ve missed the opportunity to report missing items or haven’t heard from the study team, email the study team at longcovid-t@scripps.edu. When drafting your email, please include which item(s) are missing.

I forgot to collect the blood samples before administering the first dose of the study drug. What should I do?

Please report this to the study team at longcovid-t@scripps.edu, still proceed with the collection and let them know how long after the first dose you are performing the collection.

I was unable to complete one or all of the collections. What should I do?

Please report any issues with the device to the study team. You may still ship a sample even if you think there is minimal blood in the tube. If you attempted a collection and were unable to collect blood for any reason, complete the remaining collections and ship all samples you can. In the instance of failed collections, please inform the study team. 

What’s being done with my blood samples?

The samples you donate are being shipped to different labs for various types of testing. The blood samples may be used to: 

  • Understand the different genetic materials and proteins in your blood and what viruses you may have been exposed to previously. 
  • Run tests to see how your body is responding to the medication.

Will I receive results from my blood sample collection?

The blood samples will allow us to see how things like proteins in the blood of people with Long COVID change over time, and in response to Tirzepatide. You may receive some of your blood results back via the study platform.
