Rejuveinix Mitigates Sepsis-Associated Oxidative Stress in the Brain of Mice: Clinical Impact Potential in COVID-19 and Nervous System Disorders

Here, we demonstrate that our anti-sepsis and COVID-19 drug candidate Rejuveinix (RJX) substantially improves the survival outcome in the LPS-GalN animal model of sepsis and multi-organ failure. One hundred (100) percent (%) of untreated control mice remained alive throughout the experiment. By comparison, 100% of LPS-GalN injected mice died at a median of 4.6 hours. In contrast to the invariably fatal treatment outcome of vehicle-treated control mice, 40% of mice treated with RJX (n=25) remained alive with a 2.4-fold longer median time survival time of 10.9 hours (Log-rank X2=20.60, P<0.0001). Notably, RJX increased the tissue levels of antioxidant enzymes SOD, CAT, and GSH-Px, and reduced oxidative stress in the brain. These findings demonstrate the clinical impact potential of RJX as a neuroprotective COVID-19 and sepsis drug candidate.

Non-clinical safety profile and pharmacodynamics of two formulations of the anti-sepsis drug candidate Rejuveinix

Here, we demonstrate that the two distinct formulations of our anti-sepsis drug candidate Rejuveinix (RJX) have a very favorable safety profile in Wistar Albino rats at dose levels comparable to the projected clinical dose levels. 14-day treatment with RJX-P or RJX-B similarly elevated the day 15 tissue levels of the antioxidant enzyme superoxide dismutase (SOD) as well as ascorbic acid in both the lungs and liver in a dose-dependent fashion. The activity of SOD and ascorbic acid levels were significantly higher in tissues of RJX-P or RJX-B treated rats than vehicle-treated control rats (p <0.0001). There was no statistically significant difference between tissues SOD activity or ascorbic acid levels of rats treated with RJX-P vs. rats treated with RJX-B (p >0.05). The observed elevations of the SOD and ascorbic acid levels were transient and were no longer detectable on day 28 following a 14-day recovery period. These results demonstrate that RJX-P and RJX-B are bioequivalent relative to their pharmacodynamic effects on tissue SOD and ascorbic acid levels.

Rejuveinix Reverses Severe Inflammatory Lung Damage in a Mouse Model of Fatal Sepsis

We set out to determine if our anti-sepsis drug candidate Rejuveinix (RJX) can effectively treat systemic inflammation in a mouse model of sepsis when used at a dose level that is >10-times lower than its maximum tolerated dose (MTD) for human subjects. Our findings obtained in the LPS-GalN mouse model of fatal sepsis provide experimental evidence that RJX exhibits potent single-agent anti-inflammatory activity and reverses very severe inflammatory lung injury when used therapeutically, thereby significantly improving the survival outcome. These findings demonstrate the clinical impact potential of RJX for the treatment of severe sepsis.
