Clinical Trial Summary

- There is a knowledge gap associated with the management of patients with COVID-19 lung injury and a laboratory picture compatible with disseminated intravascular coagulation (DIC). Clinical data to date support that COVID-19 is associated with a prothrombotic state that is not simply explained by an influx of more critically ill individuals. - These patients suffer from severe respiratory failure; hypoxemia and ventilator dependence are the primary concerns; ARDS with respiratory failure is frequently the cause of death. Macroscopic and probable microvascular thromboembolic events are a major concern in this population. - When DIC is associated with COVID-19, it predicts a very poor prognosis. - This study will evaluate the clinical efficacy and safety of low-dose IV bolus tenecteplase (TNK) together with anticoagulation compared with control patients on therapeutic anticoagulation alone in hospitalized adults diagnosed with COVID-19 and acute intermediate-risk PE. - Prospective, multicenter, randomized two-arm trial enrolling consecutive patients who meet enrollment criteria. - The study will generate evidence that low-dose TNK together with anticoagulation is beneficial in these patients


Clinical Trial Description

This is a prospective, double-blind, placebo-controlled study randomizing patients with acute intermediate-risk PE who meet enrollment criteria in a 2:1 manner into intervention (TNK) versus placebo arms, respectively. There will be up to 6 sites. After 18 patients are enrolled, a safety assessment will be performed by an independent Data and Safety Monitoring Board, and if a safety issue arises, it will be considered and discussed among the investigators. The planned sample size is 45 patients (30 treatment and 15 control). Subjects will be assessed daily while hospitalized. Subjects discharged from the hospital will be asked to attend study visits at Days 14 and 30 (telephone / telemedicine, clinic or inpatient ward). The overall objective of the study is to evaluate the clinical efficacy and safety of IV bolus tenecteplase (TNK) and therapeutic anticoagulation compared with placebo and therapeutic anticoagulation in hospitalized adults diagnosed with COVID-19 infection and acute intermediate-risk PE. Written informed consent for participation in the study must be obtained before performing any study-related procedures (including screening evaluations). Informed Consent Forms for enrolled patients and for patients who are not subsequently enrolled will be maintained at the study site. After informed consent is obtained, screening assessment will be completed to confirm a patient's eligibility for participation in the study. The screening visit will include medical history, physical exam and vital signs. Standard of care (SOC). labs will be reviewed. These may include INR, aPTT, PT (if patient is currently taking an anticoagulant), CBC with diff, comprehensive chemistry panel, D-dimer and Ferritin. The results of the SARS-CoV-2 will be documented. If subject is in child-bearing age and a pregnancy test was not done for SOC, a urine pregnancy test will be performed. Electrocadiogram and CTA will be reviewed. If the patient is determined to be eligible, the study site will obtain the patient's medical record number/unique patient identification number, and treatment assignment to either interventional (TNK) or placebo will be randomly determined. Patients will be allocated to the interventional versus placebo arms in a 2:1 manner as per a computer-generated randomization schedule using permuted blocks of random sizes. The block sizes will not be disclosed to ensure concealment. A total of 30 TNK subjects versus 15 placebo controls will be enrolled. Before the study drug/placebo is administered, the following labs will be drawn CBC with diff, comprehensive metabolic panel, CRP, Ferritin, IL-6, Fibrinogen, D-dimer, PT/PTT, LDH, lactate, troponin, creatinine kinase, and Thromboelastography (TEG). Vital signs and echocardiogram will be obtained. Shock Index will be calculated, then the infusion will begin. Within 10 minutes (+ 5min) of infusion, a second TEG will be collected. At 6 hours after the infusion, a second Shock Index will be calculated. At 24+/- 6 hours after the bolus, a physical exam will be performed, vital signs will be collected, an echocardiogram will be performed and D-dimer, CRP, IL-6, and Ferritin will be done. TEG will be an optional addition to the 24-hour labs. Daily safety labs will include CBC and chemistry panel. SOC lab results will be collected from the chart. Patients will have follow-up visits on Day 14 +/- 2 days and Day 30 +/- 4 days. These visits may take place via televisit or in person. Data will be collected on adverse events, vital signs and new concomitant medications. Safety labs will be obtained if visit occurs in person. ;
