Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Covid19 Drug: TM5614 Other: Placebo Phase 1 Phase 2

Detailed Description:

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.

Primary Outcome Measures :
  1. Clinical improvement [ Time Frame: 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

Secondary Outcome Measures :
  1. Sequential organ failure assessment (SOFA) score change [ Time Frame: 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).

  2. PAI-1 Levels [ Time Frame: 48 hours ]
    Change in circulating levels

  3. Ventilator free days [ Time Frame: 14 days ]
    For subjects who received mechanical ventilation, total number of days the subject was not on mechanical or non invasive mechanical ventilation while in the hospital
