Summary

This trial is testing a new medication to see if it is safe for people with ARDS from either the COVID-19 or influenza virus.

Who is the study for?
Adults with mild to severe ARDS due to COVID-19 or flu, who can consent (or have a legal rep consent), are willing to follow study procedures and allow their samples to be used for research. Excluded if on other trials recently, have certain infections like HIV/HBV/HCV/HTLV/syphilis, serious illnesses, cancer in the last 2.5 years (with exceptions), pregnant/nursing women not using contraception, listed for organ transplant (except minor ones) or on immunosuppressants.
What is being tested?
The trial is testing Lomecel-B made from stem cells against a placebo in adults with ARDS caused by COVID-19 or influenza. It's Phase I, meaning early-stage research focused on safety. Participants are randomly assigned to receive either the stem cell treatment or a placebo without knowing which one they get.
What are the potential side effects?
While specific side effects aren't detailed here as it's an early-phase trial focusing on safety, potential risks may include reactions at injection sites, immune responses like fever or chills, and possible allergic reactions due to DMSO sensitivity.
