Study of the Efficacy and Safety of Intravenous Pamrevlumab, in Hospitalized Participants With Acute COVID-19 Disease

This is a randomized, double-blind, placebo-controlled, phase 2, proof-of-concept study to evaluate the efficacy and safety of IV pamrevlumab, a monoclonal antibody, against connective-tissue growth factor (CTGF), in participants hospitalized with acute COVID-19 disease. All concomitant medications, including approved and non-approved treatments for COVID-19 (such as, hydroxychloroquine or interleukin 6 \[IL-6\] inhibitors), as well as supplemental oxygenation needs, will be collected and recorded. In addition, the following will be collected and recorded: documentation of Severe Acute Respiratory Syndrome coronavirus (SARS-Cov-2) infection, documentation of any other infection(s) prior to or during hospitalization, and whether or not aggressive care is withheld or withdrawn, including the reason for withholding or withdrawal of care (such as a Do Not Resuscitate/Do Not Intubate \[DNR/DNI\] order or a resource limitation).
