Study on Safety and Efficacy of Two Doses of PRS CK STORM in the Modulation of the Cytokine Storm in Patients With Acute Respiratory Infection Caused by SARS-Cov-2, Influenza A, Influenza B and Respiratory Syncytial Virus (RSV)
The purpose of this clinical trial is to evaluate the safety, tolerability and efficacy of two doses (dose A and dose B) of Standardized Conditioned Medium Obtained by Coculture of M2-macrophages and fat-derived Mesenchymal Stromal Cells (PRS CK STORM) in the modulation of the cytokine storm in participants with acute respiratory infection caused by SARS-Cov-2, influenza A, influenza B and respiratory syncytial virus (RSV) in need for oxygen therapy. The main questions it aims to answer are: * Are both doses of PRS CK STORM (dose A and dose B) safe as an intravenous drug to modulate inflammatory processes, such as the cytokine storm in participants with SIRS caused by SARS-Cov-2, influenza A, influenza B and RSV? * Are both doses of PRS CK STORM (dose A and dose B) effective as an intravenous drug to modulate SIRS-associated cytokine storm caused by SARS-Cov-2, influenza A, influenza B and RSV compared to the control group? * What are the anti-inflammatory and pro-inflammatory cytokine profiles after treatment with two different doses of PRS CK STORM in participants with SIRS caused by SARS-Cov-2, influenza A, influenza B and RSV? Researchers will compare both doses of PRS CK STORM with the control group to test whether the anti-inflammatory action of PRS CK STORM is safe and effective in modulating the cytokine storm for the treatment of SIRS caused by SARS-Cov-2, influenza A, influenza B and RSV. In addition, the anti-inflammatory and pro-inflammatory cytokine profiles after treatment PRS CK STORM compared to placebo group in these participants will be also studied.
