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

Phase 1

Suspended

• Conditions: Covid19
• Interventions: Drug: TM5614; Other: Placebo

• Registration Number: NCT04634799
• Lead Sponsor: Northwestern University

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.

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.

   2. History of cerebrovascular accident
   3. Recent intracranial or intraspinal surgery or trauma
   4. Intracranial neoplasm, arteriovenous malformation or aneurysm
   5. Known bleeding diathesis

• Study Design: PARALLEL

Arm && Interventions

Group	Intervention	Description
TM5614	TM5614	TM5614 30 mg tablets. 6 tablets (180 mg) taken by mouth, once daily for up to 7 days
Placebo	Placebo	Placebo tablets. 6 tablets taken by mouth, once daily for up to 7 days

Primary Outcome Measures

Name	Time	Method
Clinical improvement	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

Name	Time	Method
Sequential organ failure assessment (SOFA) score change	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).
PAI-1 Levels	48 hours	Change in circulating levels
Ventilator free days	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
