Prevention and treatment of viral infection and viral infection-induced organ failure
Compositions for and methods of preventing, reversing or treating viral infection-induced organ failure provided. The compositions are also suitable for treating and/or preventing COVID-19 and influenza. The compositions and methods employ MG53, which can be in the form of recombinant human MG53. The MG53 may also be administered as a composition that expresses and releases MG53 after in vivo administration of said composition to a subject.
1. A method of treating COVID-19 comprising administering to a subject having or at risk of having a SARS-CoV-2 infection one or more therapeutically effective doses of native recombinant human MG53.
2. The method of claim 1 , wherein said administering results in a) prevention of viral infection-induced organ failure; b) reversal of viral infection-induced organ failure; c) mitigating virus-infection induced organ fibrosis, which may or may not be fatal; or d) a combination of any thereof.
3. The method of claim 2 , wherein a) said organ failure is short-term or acute organ failure, meaning organ failure that occurs over a period of hours, days, weeks or up to about three months; orb) said organ failure is long-term or chronic organ failure, meaning organ failure that occurs over a period of about three months or more.
4. The method of claim 2 , wherein said organ is selected from the group consisting of the respiratory system, heart, lung, kidney, liver, gastrointestinal system.
5. The method of claim 1 , wherein said MG53 is administered a) acutely, chronically, or a combination thereof; b) in one or more dosage forms exhibiting one or more release profiles selected from the group consisting of immediate release, rapid release, extended release, sustained release, controlled release, enteric release, and a combination of any thereof; c) orally, by injection, intravenously, intraarterially, subcutaneously, intramuscularly, rectally, by infusion, directly to a target organ, and/or transdermally; or d) a combination of any thereof.
6. The method of claim 1 further comprising the step of administering one or more therapeutically relevant doses of one or more antiviral agents to said subject.
7. The method of claim 6 , wherein administration of MG53 and said one or more antiviral agents is separate, overlapping, sequential, or simultaneous.
8. A method of treating COVID-19 comprising administering to a subject having or at risk of having a SARS-CoV-2 infection plural therapeutically effective doses of native recombinant human MG53 over a period of at least 3 days, at least 5 days, at least one week, at least 10 days, or at least 2 weeks.
9. The method of claim 2 , wherein said mitigating is ameliorating, treating, or curing said virus-infection induced organ fibrosis, which may or may not be fatal.
