This is a prospective, randomized, comparative, multi-centric, adaptive design clinical study to evaluate efficacy, safety, and tolerability of 101-PGC-005 ('005) when used alongside standard of care (SOC) for the treatment of hospitalized patients with coronavirus disease (COVID-19).

The goal of this interventional study is to evaluate the pharmacokinetics, safety, and tolerability of 101-PGC-005 in healthy, adult, human subjects. The main question it aims to answer is what are the single and multi-dose PK properties of 101-PGC-005 in the systemic circulation
Participants will receive a bolus injection of 101-PGC-005 administered intravenously once daily for 3 consecutive days. Blood and urine samples will be collected at predetermined timepoints for analysis.

In December 2019, a novel pneumonia caused by a previously unknown pathogen emerged in Wuhan, China. The pathogen was soon identified as a novel coronavirus (SARS-CoV-2), which is closely related to severe acute respiratory syndrome CoV (SARS-CoV) COVID-19, caused by the SARS-CoV-2 virus, leading to a major global public health threat. Many COVID-19 patients develop acute respiratory distress syndrome (ARDS) leading to death. The recent RECOVERY Trial demonstrated the success of dexamethasone in treating late-stage COVID-19 patients. However, use of dexamethasone increases mortality in the early stage of the disease, and dexamethasone is further limited because the therapeutic dose and duration is insufficient to safely and effectively treat most COVID-19 patients. As the majority of cells have glucocorticoid receptors to which dexamethasone binds, highly toxic doses would be needed to effectively treat COVID-19, which results in increased mortality as well as decreased natural immunity (via T-cell and other immune cell modulation). The investigational product 101-PGC-005 ('005) - a prodrug of dexamethasone that is targeted to only activated macrophages - will address the many safety and efficacy issues that limit dexamethasone. '005 can achieve much higher anti-inflammatory doses and avoid all undesirable immunosuppressive activities caused by standard dexamethasone administration, resulting in an even greater reduction in mortality among hospitalized patients and significantly reducing long term morbidity in patients who survive.
