Clinical and Non-clinical Proof of Concept Supporting the Development of RJX As an Adjunct to Standard of Care Against Severe COVID-19
ABSTRACT Background The identification of effective strategies capable of reducing the case mortality rate of high-risk COVID-19 is an urgent and unmet medical need. We recently reported the clinical safety profile of RJX, a well-defined intravenous GMP-grade pharmaceutical formulation of anti-oxidant and anti-inflammatory vitamins as active ingredients, in a Phase 1 study in healthy volunteers (<jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://ClinicalTrials.gov">ClinicalTrials.gov</jats:ext-link>Identifier:<jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="clintrialgov" xlink:href="NCT03680105">NCT03680105</jats:ext-link>) (Uckun et al., Front. Pharmacol. 11, 594321. 10.3389/fphar.2020.594321). Here we report data from a pilot clinical study (RPI-015) which examined the safety, tolerability, and feasibility of using RJX in combination with clinical standard of care (SOC) in hospitalized COVID-19 patients with pneumonia (<jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://ClinicalTrials.gov">ClinicalTrials.gov</jats:ext-link>Identifier:<jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="clintrialgov" xlink:href="NCT04708340">NCT04708340</jats:ext-link>). In addition to our early clinical proof of concept (POC) data, we also present non-clinical POC from a mouse model of CRS and ARDS that informed the design of the reported clinical study.Methods 13 patients, who were hospitalized with COVID-19 pneumonia and abnormally elevated serum inflammatory biomarkers markers ≥3 months prior to the identification of the first confirmed U.S case of the Omicron variant, were treated with IV RJX (daily x 7 days) plus SOC. Non-clinical POC study examined the ability of RJX plus dexamethasone (DEX) to improve the survival outcome in the lipopolysaccharide (LPS)-Galactosamine (GalN) mouse model of fatal cytokine release syndrome (CRS), sepsis and acute respiratory distress syndrome (ARDS).Findings In the Phase 1 clinical study, none of the 13 patients developed a treatment-related DLT, SAE, or Grade 3-5 AEs. Nine (9) of the 12 evaluable patients, including 3 patients with hypoxemic respiratory failure, showed rapid clinical recovery. In the non-clinical POC study in LPS-GalN challenged mice, the combination of RJX plus DEX was more effective than RJX alone or DEX alone, reversed the CRS as well as inflammatory tissue damage in the lungs and liver, and improved the survival outcome. Taken together, these findings provide the early clinical and non-clinical POC for the development of RJX as an adjunct to the SOC in the multi-modality management of high-risk COVID-19..
