This is a placebo-controlled, double blind, randomized, Phase II dose escalation study intended to evaluate the potential safety and efficacy of tenecteplase for the treatment of COVID-19 associated respiratory failure. The hypothesis is that administration of the drug, in conjunction with heparin anticoagulation, will improve patients' clinical outcomes.
