Double-blinded, randomized, placebo-controlled study with 2 cohorts.~Cohort 1: Subjects with ARDS and acutely infected with SARS-CoV-2. Arm 1: 25 subjects treated with up to 3 doses of 100 million Lomecel-B Arm 2: 10 subjects treated with up to 3 doses of Placebo.~Cohort 2: Subjects with ARDS and acutely infected with influenza virus. Arm 3: 25 subjects treated with up to 3 doses of 100 million Lomecel-B Arm 4: 10 subjects treated with up to 3 doses of Placebo.~Each subject will be intravenously infused with 100 million Lomecel-B (formerly LMSCs) or placebo on Day 0. If no treatment-related AEs are seen after the infusion, a second infusion will be given on Day 3. If no treatment-related AEs are seen after the second infusion, a third infusion will be given Day 6.~Follow-up visits will be conducted: daily until hospital discharge; at Week 4 after treatment (with LMSCs or placebo) for patients already discharged; and at Month 6 after treatment (with LMSCs or placebo).
