Summary

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.

Detailed description

This prospective Phase IIa study will evaluate the safety of '005 for moderate to severe COVID-19 disease along with Standard of Care (SOC) treatment. The Nineteen (19) eligible patients will be enrolled to receive '005 + SOC, 10 additional patients will be enrolled to a control group receiving the SOC together with placebo. At the first open-label stage, 3+3+3 design will be implemented. Three (3) patients will be enrolled to receive 10mg '005 together with SOC, three (3) patients will receive 20mg'005 together with SOC, and three (3) patients will receive 30mg '005 together with SOC if no safety concerns are identified the second stage will be initiated. At the second double blind stage neither the participants nor the investigator will know which treatment participants are receiving until the clinical trial is over \[20 patients will be enrolled and randomly allocated in a 1:1 ratio to the treatment (SOC +'005) or placebo group (SOC + placebo)\]. The treatment dose will be chosen based on the first stage safety results. NOTE: '005 will be administered daily for three (3) consecutive days starting from the day of enrollment. Standard of Care will be administered as long as required, per Investigator's judgment, institutional practice, or local, national, or international guidelines for COVID-19 management. A screening period of up to 7 days (Day-7 to Day-1) prior to enrollment will be followed by a study period of 28 days. Patients will be administered '005 daily from Day-1 to Day 3. Total duration of study participation will not exceed 35 days.
