About this study

The IMPACT Long Covid Treatment clinical study (IMPACT-LC) is testing two repurposed and previously approved drugs, Maraviroc and Atorvastatin, for the treatment of non-hospitalized subjects with Long COVID. The main goals of the clinical study are to determine if this combination drug therapy can improve neurocognitive and physical functions in Long Covid patients, such as fatigue severity, heart rate, blood pressure, digestion, breathing, dizziness, and cognitive function. A secondary goal is to determine if biomarker levels, measured by a diagnostic test, can improve during treatment. To qualify for the trial, a subject must be an adult ≥ 18 and ≤ 65 years of age and meets the WHO-defined post-COVID-19 condition and has one or more new-onset Long Covid symptom that persist ≥ 3 months after the diagnosis of acute COVID-19 infection. A total of 252 participants will take either two daily doses of two existing medications (Maraviroc and Atorvastatin together as separate tablets) or a placebo (pills with no active ingredient) for 16 weeks. Although these medications are not yet approved for Long Covid, they are FDA-approved for use in treating other health conditions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fatigue

    Fatigue will be measured via PROMIS Fatigue v1.0. The PROMIS Fatigue 10a assesses fatigue severity in the previous week. Fatigue is divided into the experience of fatigue (frequency, duration, and intensity) and the impact of fatigue on physical, mental, and social activities. The instrument translates the total raw score into a T-score with a mean of 50 and a standard deviation of 10. A score of 50 is the average for the United States general population (SD=10).

    Measured: PROMIS Fatigue scores will be taken during screening (0-28 days before the first baseline) and at the EOT visit, week 12.

Secondary outcomes (6)
  1. Improvement in dysautonomia symptoms as reflected by the Composite Autonomic Symptom Score (COMPASS-31)

    To assess the effect of the combination of maraviroc and atorvastatin, compared with placebo, on dysautonomia symptoms 12 weeks after treatment initiation in individuals with Long COVID.

    Measured: Scores will be determined at Visit 1 (Day 1) and EOT (week -12)

  2. Improved Cognitive Function, measured by the PROMIS (Patient-Reported Outcomes Measurement Information System) Cognitive Function v.2.0 - Short Form 6a

    The PROMIS (Patient-Reported Outcomes Measurement Information System) Cognitive Function v.2.0 - Short Form 6a is a 6-item sub-set scale of the PROMIS Cognitive Function item bank that assesses patient-perceived cognitive deficits. Each item has five response options ranging in value from one to five. The total raw score for a short form with all questions answered, is the sum of the values of the response to each question and ranges between 6 and 30. The raw score is translated in a T-score, a standardized score with a mean of 50 and a standard deviation (SD) of 10.

    Measured: Difference in T-score measured at Visit 1 (Day 1) and EOT (week-12)

  3. To assess if maraviroc and atorvastatin decrease the Long Hauler Index (LHI) from baseline to week 12.

    To assess the effect of the combination of maraviroc and atorvastatin, compared with placebo, on the LHI 12 weeks after treatment initiation in individuals with Long COVID.

    Measured: LHI will be measured at Screening and EOT (week-12)

  4. To assess the proportion of participants with a PROMIS Fatigue T-score improvement from baseline ≥5 points 12 weeks after treatment initiation.

    In subjects with Long COVID complying with the key protocol criteria (evaluable participants) who received 12 weeks of study treatment:

    ● Change in the proportion of subjects who improve their PROMIS T-score from baseline to week 12 in maraviroc/atorvastatin and placebo groups.

    Measured: From baseline Visit 1 (Day-1) and EOT (week-12)

  5. To determine the safety profile of maraviroc and atorvastatin in patients treated for Long COVID-19

    Participants report data will be compiled as follows:

    Percentage of participants reporting AEs from Dose 1 to 28 days after the last dose.

    Percentage of participants reporting SAEs from Dose 1 to 28 days after the last dose.

    Percentage of participants reporting AEs leading to discontinuation. Percentage of participants reporting SAEs leading to discontinuation.

    Measured: Adverse event collection will be done during every Visit (Day-1, Week-4, Week-8, Week-12, Week-16 (EOT) and EOS (28-42 Days after last dose)

  6. To evaluate IncellKINE Biomarkers

    To assess the effect of the combination of maraviroc and atorvastatin, compared with placebo, on IncellKINE biomarker levels in individuals with Long COVID 12 weeks after treatment initiation.

    Measured: Screening and EOT (week-12)

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Maraviroc (MVC) and Atorvastatin, 10mg, 20mg, 40mg in people with Long COVID, run by HealthBio, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 38 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 18 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Brad Fox (623-824-9165, bradfoxaz@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fatigue (time frame: PROMIS Fatigue scores will be taken during screening (0-28 days before the first baseline) and at the EOT visit, week 12.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jun 2026.
