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

2026年9月24日 更新者：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.

详细说明

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.

描述

Inclusion Criteria:

  1. Adults ≥65 years old or < 65 years old AND at least one major cardiometabolic comorbidity (diabetes, hypertension, or cardiovascular disease)
  2. Established diagnosis of COVID-19 as evidenced by a positive nasopharyngeal or bronchoalveolar lavage viral PCR for SARS-CoV2
  3. Requiring supplemental oxygen

Exclusion Criteria:

  1. Age <18 years old

  2. Pregnancy or breast-feeding

  3. Known contraindication to tissue plasminogen activator (tPA), including

    1. Active internal bleeding
    2. History of cerebrovascular accident
    3. Recent intracranial or intraspinal surgery or trauma
    4. Intracranial neoplasm, arteriovenous malformation or aneurysm
    5. Known bleeding diathesis
    6. Severe uncontrolled hypertension (SBP>200 persistently >12 hours)

  4. Currently receiving therapeutic dose anticoagulation (specifically will exclude those with potential drug-drug interaction such as heparin, apixaban, warfarin)

  5. Platelets <50,000

  7. Not hemodynamically stable in the preceding 4 hours (symptomatic hypotension or systolic BP <95 mmHg at 2 out of 3 measurements)

  8. Concomitant illness, physical impairment or mental condition which in the opinion of the study team / primary care physician could interfere with the conduct of the study including outcome assessment

  9. Other patient characteristics (not thought to be related to COVID-19) that portend a very poor prognosis (e.g., severe liver failure, metastatic malignancy)

  10. Participation in a concurrent interventional medical investigation or pharmacologic clinical trial. Patients in observational, natural history or epidemiological studies not involving an intervention are eligible.

  11. Participant's responsible attending physician believes it is not appropriate for participant to participate in the study.

  12. Inability or unwillingness to provide written informed consent

  13. Involvement in the planning and/or conduct of the study

  14. Previous randomization in the present study

  15. Unable to complete study procedures.

  16. Patients with active venothromboembolic disease

  17. Patients who are receiving other investigational agents for COVID-19.

主要结果指标

结果测量
措施说明
大体时间
Clinical Improvement
大体时间：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)
  6. Hospitalized, requiring neither supplemental oxygen nor ongoing medical care (other than that specified in the protocol)
  7. Not hospitalized

大体时间
Sequential Organ Failure Assessment (SOFA) Score Change
大体时间：7 Days

Change in degree of organ dysfunction as defined by the Sequential Organ Failure Assessment (SOFA) Score.

The SOFA score ranges from 0 to 24 (higher scores indicate more severe organ failure), with 0 to 4 points assigned for each of 6 organ dysfunctions (ie, central nervous system, cardiovascular, respiratory, renal, coagulation, and liver).
