Details and patient eligibility

About

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.

Full 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.

Requiring supplemental oxygen

Exclusion criteria

Age <18 years old
Pregnancy or breast-feeding
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)
Currently receiving therapeutic dose anticoagulation (specifically will exclude those with potential drug-drug interaction such as heparin, apixaban, warfarin)

Not hemodynamically stable in the preceding 4 hours (symptomatic hypotension or systolic BP <95 mmHg at 2 out of 3 measurements)
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
Other patient characteristics (not thought to be related to COVID-19) that portend a very poor prognosis (e.g., severe liver failure, metastatic malignancy)
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.
Participant's responsible attending physician believes it is not appropriate for participant to participate in the study.
Inability or unwillingness to provide written informed consent
Involvement in the planning and/or conduct of the study
Previous randomization in the present study
Unable to complete study procedures.
Patients with active venothromboembolic disease
Patients who are receiving other investigational agents for COVID-19.
