Study To antagOnize Plasminogen Activator Inhibitor-1 in Severe COVID-19

24. september 2026 opdateret af: Sanjiv Shah, Northwestern University

Study To antagOnize Plasminogen Activator Inhibitor-1 in Severe COVID-19 (STOP Severe COVID-19)

This is a single-center, randomized double blind placebo controlled trial to evaluate the efficacy and safety of novel PAI-1 inhibitor (TM5614) for high-risk patients hospitalized with severe COVID-19 at Northwestern Memorial Hospital. The patients will be randomized in a 1:1 ratio to receive standard of care plus TM5614 or standard of care plus placebo.

Detaljeret beskrivelse

This project will evaluate the efficacy and safety of a novel small molecule therapy targeting PAI-1 (TM5614) for patients with severe COVID-19. This is a randomized (1:1), double-blinded trial that will enroll adult patients (> 65 years OR <65 years with at least one major cardiometabolic comorbidity [diabetes, hypertension, or cardiovascular disease]) with COVID-19 requiring supplemental oxygen. The study intervention will be a small molecule inhibitor of PAI-1, TM5614, up to 180 mg, compared to matching placebo for up to 7 days.

Research blood samples for PAI-1 and C-reactive protein (CRP) will be collected at time of enrollment, 48 hours after 1st dose of medication and at day 7 or discharge, whichever comes first.

These objectives will allow for the planning of subsequent phase 3 study, and strengthen implementation of a multi-center randomized trial should this study confirm safety, and suggest efficacy of therapy.

    4. Intracranial neoplasm, arteriovenous malformation or aneurysm
    5. Known bleeding diathesis

Foranstaltningsbeskrivelse
Tidsramme
Clinical Improvement
Tidsramme: 7 Days

Change of at least 2 points in the NIAID-defined ordinal scale (higher scores indicate improved outcome),:

  1. Death
  2. Hospitalized, receiving invasive mechanical ventilation or ECMO
  3. Hospitalized, receiving noninvasive ventilation or high-flow oxygen devices
  4. Hospitalized, requiring low-flow supplemental oxygen
  5. Hospitalized, not requiring supplemental oxygen but receiving ongoing medical care (related or not related to Covid-19)
