A significant minority of patients infected with the new coronavirus, SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), develop viral pneumonia that causes an acute lung injury (ALI) capable of rapid progression to viral sepsis and acute respiratory distress syndrome (ARDS) with a high fatality rate especially if they are older and have comorbidities. A systemic inflammatory response syndrome, also referred to as cytokine storm or cytokine release syndrome (CRS), contributes to the development of ARDS and often irreversible multi-organ dysfunction syndrome (MODS) associated with the severe-critical forms of COVID-19. Approximately 20% of COVID-19 patients with mild-moderate disease progress to severe-critical disease, and this percentage increases to 40% for the high-risk subgroup ≥65 years of age with comorbidities or laboratory parameters indicative of systemic inflammation, such as high levels of C-reactive protein (CRP), lactate dehydrogenase (LDH), and Ferritin or dysfunction of the coagulation system, as evidenced by elevated D-dimer levels. High-risk patients not only have a higher incidence of ARDS owing to severe viral sepsis caused by SARS-CoV-2, but they also progress faster and have a significantly higher case mortality rate. COVID-19 patients with an underlying cancer, especially if they are undergoing chemotherapy, are at an augmented risk for developing potentially fatal ARDS and multi-organ failure. Therefore, treatment platforms capable of preventing the disease progression and/or reducing the case mortality rate in such high-risk COVID-19 patients are urgently needed.

See below for exemplary, non-limiting, volumes of pharmaceutical composition that may be delivered in one dose. One dose of the pharmaceutical composition may comprise an amount of the dexamethasone corresponding one of the foregoing dexamethasone doses. A non-limiting guideline for selecting a dexamethasone dose, and from that a concentration for the volume of pharmaceutical composition delivered in one dose, follows. When used alone, a dose of the dexamethasone may be 1-2 mg per administration, 4-8 mg per administration, or 10-20 mg per administration to treat mild, moderate, or severe inflammation, respectively. The frequency of administration may vary from 1-3 times per day. When in the combination of the pharmaceutical composition, the dose of the dexamethasone designed for treating mild or moderate inflammation (as a non-limiting example, 2-4 mg instead of 10-20 mg per dose) may be sufficient to treat severe inflammation, and the concentration of dexamethasone in the pharmaceutical composition may be adjusted accordingly.
The following Conversion Table provides a guide to determining a dose, and thereby the concentration in a volume of pharmaceutical composition to be delivered, for the cortisone, hydrocortisone, methylprednisolone, prednisolone, prednisone, triamcinolone, betamethasone, or fludrocortisone based on the above described doses for dexamethasone. One dose of the pharamaceutical composition may comprise an amount of one or more of cortisone, hydrocortisone, methylprednisolone, prednisolone, prednisone, triamcinolone, betamethasone, fludricortisone or dexamethasone to be about an equivalent to a dose of dexamethasone as described herein.
A dose for one of the other anti-inflammatory steroid may be as set forth above for dexamethasone. Or it may by adjusted based on a selected dexamethasone dose and using the above Conversion Table where the dose of the other anti-inflammatory steroid is calculated by [(approximate equivalent dose of the other anti-inflammatory steroid)/0.75]×(selected dexamethasone dose). The concentration in the pharmaceutical composition may then be arrived at by using the volume of pharmaceutical composition per administration. See below for exemplary, non-limiting volumes that may be used.
As shown in the Conversion Table, the half-life of the different steroids varies and this gives rise to a different duration of action. 8-12 hour half life is considered short-acting, 18-36 hour half-life is considered intermediate-acting, and 36-54 hour half-life is considered long-acting. One guideline to choosing one anti-inflammatory steroid, or a combination of two or more, may be the duration of action for each anti-inflammatory steroid. For example, a combination of more than one anti-inflammatory steroid may include two or three different durations of action.
An embodiment comprises a pre-formulation of any pharmaceutical composition herein. The pre-formulation may be 50-100 fold more concentrated than the pharmaceutical composition. The concentrate may be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, or 100 fold more concentrated, or a fold more concentrated in a range between any two of the foregoing, compared to a pharmaceutical composition herein. The concentration of a constituent of the pre-formulation may be arrived at by selecting the constituent from the above, selecting one of the exemplary concentrations for the constituent, and multiplying by the fold more concentrated value selected. The magnesium sulfate may be at a concentration of 50 to 100× (0.7 to 0.9 mg/mL). The ascorbic acid may be at a concentration of 50 to 100× (0.8 to 1.0 mg/mL).

The frequency of administration may vary from 1-3 times per day. When administered in combination with the pharmaceutical composition, the dose of the dexamethasone designed for treating mild or moderate inflammation (as a non-limiting example, 2-4 mg instead of 10-20 mg per dose) may be sufficient to treat severe inflammation, and the dose of dexamethasone may be adjusted accordingly.
The above Conversion Table provides a guide to determining a dose for the cortisone, hydrocortisone, methyiprednisolone, prednisolone, prednisone, triamcinolone, betamethasone, or fludrocortisone based on the above described doses for dexamethasone:
A dose for one of the other anti-inflammatory steroid may be as set forth above for dexamethasone. Or it may by adjusted based on a selected dexamethasone does and using the above Conversion Table where the dose of the other anti-inflammatory steroid is calculated by [(approximate equivalent dose of the other anti-inflammatory steroid)/0.75]×(the selected dexamethasone dose). As shown in the Conversion Table, the half-life of the different steroids varies and this gives rise to a different duration of action. 8-12 hour half life is considered short-acting, 18-36 hour half-life is considered intermediate-acting, and 36-54 hour half-life is considered long-acting. One guideline to choosing one anti-inflammatory steroid, or a combination of two or more, may be the duration of action for each anti-inflammatory steroid. For example, a combination of more than one anti-inflammatory steroid administered may include two or three different durations of action. A dose of the at least one anti-inflammatory drug selected from anti-inflammatory steroids may comprise an amount of one or more of cortisone, hydrocortisone, methylprednisolone, prednisolone, prednisone, triamcinolone, betamethasone, fludrocortisone or dexamethasone to be an equivalent to a dose of dexamethasone as described herein.
For treatment of systemic inflammation in COVID-19 patients a dose of anti-inflammatory drug administered may be as described above. A dose may be 6 mg dexamethasone. When COVID-19 patients develop cytokine release syndrome (CRS), also known as cytokine storm, a dose of dexamethasone may be 20 mg, and the administration may be 1×-3×/day. In such patients, a combination of 6 mg dexamethasone and low dose RJX at 0.2-0.3 cc/kg was effective in reversing the systemic inflammation.

New treatment platforms that can prevent acute respiratory distress syndrome (ARDS) or reduce its mortality rate in high-risk COVID-19 patients, such as those with an underlying cancer, are urgently needed. Rejuveinix (RJX) is a formulation of several vitamins, including ascorbic acid (Vitamin C), cyanocobalamin (Vitamin B12), thiamine hydrochloride (Vitamin B1), riboflavin 5′ phosphate (Vitamin B2), niacinamide (Vitamin B3), pyridoxine hydrochloride (Vitamin B6), calcium D-pantothenate, and magnesium sulphate as a potent calcium antagonist, representing components that have been studied in animal models of septic shock and ARDS as well as clinical studies in septic patients. RJX has a very favorable safety profile in human subjects. RJX is being developed as an anti-inflammatory and anti-oxidant treatment platform for patients with sepsis, including COVID-19 patients with viral sepsis and ARDS. A nonclinical pharmacodynamic study it analyzed if RJX can improve the survival outcome of mice challenged with an otherwise invariably fatal dose of LPS-GalN in a model of sepsis, ARDS and multi-organ failure. RJX exhibited potent protective anti-CRS and anti-ARDS activity in the LPS-GalN model at clinically safe low dose levels.
The ability of RJX to prevent fatal shock, ARDS, and multi-organ failure was examined in the well-established lipopolysaccharide (LPS)-Galactosamine (GalN) mouse model of sepsis and ARDS. Standard methods were employed for the statistical analysis of data in both studies. No participant developed serious adverse events (SAEs) or Grade 3-Grade 4 adverse events (AEs) or prematurely discontinued participation from the study. In a non-clinical study, RJX exhibited potent and dose-dependent protective activity, decreased the inflammatory cytokine responses (IL-6, TNF-α, TGF-β), and improved survival in the LPS-GalN mouse model of ARDS. Histopathological examinations showed that RJX attenuated the LPS-GalN induced acute lung injury (ALI) and pulmonary edema as well as liver damage. Conclusion. RJX showed a very favorable safety profile and tolerability in human subjects. It show potential to favorably affect the clinical course of high-risk COVID-19 by preventing ARDS and its complications.
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 5.4 hours (
Groups of 10 BALB/C mice were treated with i.p injections of RJX (4.2 mL/kg, 0.5 ml/mouse) or vehicle 2 hours before or post-injection of LPS-GalN. Except for untreated mice (Control), each mouse received 0.5 ml of LPS-GalN (consisting of 100 ng of LPS plus 8 mg of D-galactosamine) i.p. Survival is shown as a function of time after the LPS-GalN challenge. Depicted are the survival curves of the different treatment groups. Depicted are the Kaplan-Meier survival curves for each group along with the median survival times and log-rank P-value for the comparison of LPS-GalN+RJX group with the LPS/GaIN+NS group.
In LPS-GalN challenged control mice not receiving any RJX treatments, serum IL-6, TNF-α and LDH levels were drastically increased at the time of death which is consistent with a “cytokine storm” and marked systemic inflammation. See
In contrast, RJX-treated mice that died after LPS-GalN injection had significantly lower levels of IL-6, TNF-α, as well as LDH (
When compared to untreated control mice, the lung MDA levels measuring lipid peroxidation were markedly elevated in LPS-GalN challenged mice (6.5±0.5 vs. 2.6±0.4 nmol/g, P<0.0001). Conversely, their tissue levels of the antioxidant enzymes SOD (30.5±1.2 U/mg vs. 80.4±1.6 U/mg, P<0.0001), CAT (19.9±1.1 U/mg vs. 56.7±1.4 U/mg, P<0.0001), GSH-Px (54.2±3.1 U/mg vs. 126.4±4.1 U/mg, P<0.0001), as well as ascorbic acid (54.5±0.1 μg/g vs. 398.2±0.1 μg/g, P<0.0001) in the lung were markedly reduced consistent with severe oxidative stress in the lung tissue. See
Histopathological examination of hematoxylin-eosin (H/E)-stained lung tissues from LPS-GalN injected mice showed histological changes consistent with severe acute ALI, including alveolar hemorrhage, thickening of alveolar wall, edema/congestion, and leukocyte infiltration (
Referring to
The liver MDA levels measuring lipid peroxidation were markedly elevated and the levels of the antioxidant enzymes SOD, CAT, GSH-Px, as well as ascorbic acid were markedly reduced in LPS-GalN treated mice consistent with severe oxidative stress (
Furthermore, RJX decreased the liver MDA levels and normalized in a dose-dependent manner the reduced levels of the antioxidant enzymes SOD, CAT, and GSH-Px as well as ascorbic acid.
In
LPS-GalN caused significant liver damage and hepatic dysfunction in mice with a marked elevation of the liver enzymes as well as total bilirubin when compared to the enzyme levels in untreated healthy control mice: ALT (1297.1±106.8 vs. 28.3±4.5; 46-fold elevation; P<0.0001), AST (1756.0±96.8 vs. 57.9±10.3; 30-fold elevation; P<0.0001), ALP (491.2±33.9 vs. 69.9±6.7; 7-fold elevation; P<0.0001), total bilirubin (TBIL) (1.9±0.1 vs. 0.3±0.1; 6-3 fold elevation; P<0001) (
Histopathologic examination of the livers from LPS-GalN treated mice showed massive generalized hepatocyte vacuolation and necrosis corresponding to >25% necrosis and destruction of the liver parenchyma, severe lobular inflammation involving >50% of the liver parenchyma, and severe portal inflammation involving more than >50% of portal tracts. RJX suppressed the LPS-GalN induced liver injury and inflammation, as documented by reduction of the histopathological scores measuring liver damage (
No histopathologic lesions were observed in the heart of any of the mice challenged with LPS-GalN. However, the serum cardiac troponin I (cTnI) levels were markedly elevated at the time of death after the LPS-GalN challenge, which is consistent with myocardial injury. Furthermore, the cardiac MDA levels measuring lipid peroxidation were markedly elevated and the levels of the antioxidant enzymes SOD, CAT, and GSH-Px were markedly reduced in the heart of the LPS-GalN treated mice consistent with severe oxidative stress (
Referring to
Referring to
Notably, our results in the aforementioned animal model have demonstrated that RJX treatments result in a marked reduction of IL-6 and TNF-α in the serum, and IL-6, TNF-α as well as TGF-ß levels in the lungs as well as liver of mice challenged with LPS-GalN in a dose-dependent fashion. It is postulated that the RJX-mediated suppression of inflammatory cytokine expression in the lungs and other tissues will accelerate the resolution of systemic inflammation of MIS-C patients by reducing the contributions of these cytokines to MIS-C and its complications. Therefore, RJX has the potential to emerge as a clinically useful adjunct to the best available standard of care and supportive care in pediatric COVID-19 patients who develop MIS-C.
It was next sought to determine whether RJX could also improve the survival outcome of LPS-GalN challenged mice if the treatment is delayed until after the onset of the inflammatory cytokine response.
As shown in
Referring to
Rejuveinix (RJX) is a formulation of several vitamins, including ascorbic acid (Vitamin C), cyanocobalamin (Vitamin B12), thiamine hydrochloride (Vitamin B1), riboflavin 5′ phosphate (Vitamin B2), niacinamide (Vitamin B3), pyridoxine hydrochloride (Vitamin B6), calcium D-pantothenate, and magnesium sulphate as a potent calcium antagonist, representing components with reported, albeit controversial, protective activity in animal models of septic shock and ARDS as well as some of the clinical studies in septic patients. Increased lactate levels contribute to the enhanced mortality of septic patients. Two of the RJX ingredients, thiamine and magnesium sulfate, accelerate the lactate clearance, which has been shown to improve survival outcomes. While some precinical, translational, early-stage, as well as late-stage clinical studies, have yielded promising positive data regarding the clinical impact potential of ascorbic acid, thiamine, riboflavin, niacinamide, and pyridoxine (Vit. B6) in the prevention and treatment of cytokine storm, CRS, coagulopathy, ALI, acute kidney injury (AKI), ARDS, and MODS in the context of sepsis, other studies have not shown any meaningful activity. For example, Moskowitz et al. recently reported the results of a 205-patient, randomized blinded, multicenter study of ascorbic acid, thiamine and steroids in patients with septic shock that was performed at 14 centers in the U.S. Patients were randomly assigned to receive parenteral ascorbic acid (1500 mg), hydrocortisone (50 mg), and thiamine (100 mg) every 6 hours for 4 days (n=103) or placebo in matching volumes at the same time points (n=102). The primary endpoint was change in the Sequential Organ Failure Assessment (SOFA) score (range, 0-24; 0=best) between enrollment and 72 hours. There was no statistically significant interaction between time and treatment group with regard to SOFA score over the 72 hours after enrollment. Hence, the combination of ascorbic acid, corticosteroids, and thiamine, compared with placebo, did not result in a statistically significant reduction in SOFA score during the first 72 hours after enrollment. Similarly, Fujii et al. reported that treatment with intravenous vitamin C, hydrocortisone, and thiamine does not lead to a more rapid resolution of septic shock compared with intravenous hydrocortisone alone based on the results of a randomized trial in 216 patients with septic shock. In contrast to these studies, Iglesias et al. reported that the combination of IV ascorbic acid, thiamine, and hydrocortisone significantly reduced the time to resolution of shock based on another randomized study. Likewise, Byerly et al. reported that ascorbic acid plus thiamine is associated with increased survival in septic ICU patients based on the results of 11,330 patients with sepsis and elevated lactate levels regarding the impact of thiamine and ascorbic acid on survival outcome. After controlling for confounding factors, ascorbic acid (adjusted odds ratio [AOR], 0.69 [0.50-0.95]) and thiamine (AOR, 0.71 [0.55-0.93]) were independently associated with survival. Additional studies are needed to confirm these findings and assess any potential benefit from this treatment. RJX has no steroids and it contains niacinamide, pyridoxine, cyanocobalamine and Mg-sulfate in addition to ascorbic acid and thiamine. The clinical potential of RJX will be examined in COVID-19 patients with an emphasis on prevention of ARDS and multiorgan failure in COVID-19 patients at high risk for fatal viral sepsis rather than treatment of septic shock.
RJX is being developed as an anti-inflammatory and anti-oxidant treatment platform for patients with sepsis, including COVID-19 patients with viral sepsis and ARDS. Its clinical safety profile was examined in a clinical study.
Specifically, a Phase I, double-blind, placebo-controlled, randomized, two-part, ascending dose-escalation study was performed in participating 76 healthy volunteer human subjects in compliance with the ICH(E6) good clinical practice (GCP) guidelines to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of RJX. In the Phase I clinical study, RJX showed a very favorable safety profile and tolerability in human subjects. No participant developed serious adverse events (SAEs) or Grade 3-Grade 4 adverse events (AEs) or prematurely discontinued participation from the study.
The dose levels ranged from 0.024 mL/kg to 0.759 mL/kg in Part 1 and from 0.240 mL/kg to 0.759 mL/kg in Part 2. No deaths or SAEs were reported, none of the 39 RJX-treated subjects experienced Grade 3 or 4 AEs, and no AEs led to discontinuation of RJX.
In Part 2, no SAEs and no Grade 3 or 4 AEs were encountered by any of the 18 RJX-treated subjects. One subject in Cohort 1 developed a mild upper respiratory infection (URI); 3 subjects in Cohort 2 had mild infusion site discomfort, pain or reaction; and 3 subjects on Cohort 3 experienced mild-moderate pain (mild headache=1; mild pain in extremity=1, moderate back pain=1). The TEAEs in 2 of the subjects were considered possibly or probably related to RJX. Both patients were in Cohort 2: One patient had a mild infusion site discomfort on day 6 considered possibly related to RJX and another patient had a mild infusion site pain on days 6 and 7 considered probably related to RJX infusion. These TEAEs did not require additional treatment, and they did not cause discontinuation of the dosing or study. All AEs considered possibly or probably related to RJX infusions have recovered/resolved with no sequelae. There were no clinically significant abnormal findings in 12-lead safety ECGs, and no notable changes were detected compared with baseline. For both study parts, there were no clinically meaningful changes in laboratory values identified in observed values or mean changes from baseline compared with placebo or evaluated by increasing the RJX dose level. Based on its tolerability, the 0.500 ml/kg dose level was selected as the recommended Phase 2 dose (RP2D) level for future studies.
The experimental drug product RJX is being evaluated for its clinical impact potential for COVID-19-associated viral sepsis in a placebo-controlled randomized Phase I/II study. Here, we demonstrate that RJX, at a dose level that corresponds to less than 10% of its clinical maximum tolerated dose (MTD), exhibits potent anti-inflammatory activity in the preclinical LPS-GalN model of fatal sepsis. The combination of RJX plus dexamethasone (DEX) was more effective than RJX alone or DEX alone and (i) profoundly decreased the inflammatory cytokine responses to LPS-GalN (ii) mitigated the inflammatory tissue damage in the lungs and liver, and (iii) prevented a fatal outcome. Even when treatments were started after the onset of fulminant cytokine storm and systemic inflammation with severe lung damage, a near-complete recovery of the inflammatory lung injury was achieved within 24 hours. RJX may be an adjunct of standard of care in the multi-modality management of sepsis and its complications. The complications may be acute respiratory distress syndrome (ARDS) and multi-organ dysfunction (MOD).
Sepsis represents a strong systemic inflammatory response to an infection with a potentially fatal outcome due to its complications. Severe viral sepsis caused by SARS-CoV-2 shows a rapid progression associated with cytokine release syndrome (CRS) and a high case fatality rate in high-risk coronavirus disease 2019 (COVID-19) patients. The anti-sepsis drug Rejuveinix (RJX) exhibited promising single-agent anti-inflammatory activity in mice challenged with LPS-GalN. RJX showed a very favorable clinical safety and pharmacokinetics (PK) profile in a recently completed randomized, double-blind, placebo-controlled Phase I ascending dose-escalation study in healthy volunteers. No deaths, serious adverse events (SAEs), or Grade 3-4 adverse events (AEs) were observed in any of 57 healthy volunteers treated with RJX at dose levels ranging from 0.024 mL/kg to 0.759 mL/kg.
The primary objective of the present example was to compare the effects of RJX, the standard anti-inflammatory drug dexamethasone (DEX), and their combination on the severity of sepsis and survival outcome in an animal model that employs LPS-GalN to induce fatal sepsis. It was hypothesized that RJX, especially when combined with DEX, would improve the survival outcome of mice challenged with a lethal dose of LPS-GalN. This example demonstrates that RJX—at a dose level >10-fold lower than its clinical MTD-exhibits potent single-agent anti-inflammatory activity in the LPS-GalN model. The combination of RJX plus DEX immediately and profoundly decreased the inflammatory cytokine (IL-6, TNF-α) responses to LPS-GalN, mitigated the inflammatory tissue damage in the lungs and liver, and prevented a fatal outcome. Even when treatments were started after the onset of fulminant cytokine storm and systemic inflammation as well as very severe lung damage, a near-complete recovery of the inflammatory lung injury was achieved within 24 hours, and the survival outcome was improved.
It is anticipated that RJX in combination with other anti-inflammatory drugs as provided herein will lead to similar results.
LPS-GalN-challenged mice experience a rapid onset systemic inflammation with markedly elevated inflammatory cytokine levels as well as severe lung injury as early as 2 hours after the administration of LPS-GalN. It was first set out to determine the effects of RJX vs. DEX on the LPS-GalN induced inflammatory cytokine response in BALB/c mice.
The observed reversal of the inflammatory cytokine response by RJX was associated with a significant improvement of the survival outcome in this LPS-GalN model of sepsis. Notably, 0.7 ml/kg low dose RJX was moderately more effective than DEX at a 0.1 mg/kg low dose level (Median survival: 15.1 h vs. 5.1 h; 24-h mortality: 50% vs. 83.3%), and it was as effective as DEX at the standard dose 0.6 mg/kg. See
Notably, at a dose level of 1.4 ml/kg, which corresponds to 15% of its clinical MTD, RJX reduced the mortality to 40% (Median survival >24 h). These results were very similar to and statistically not different from the 33.3% mortality (Median survival >24 h) (P=0.99) achieved with DEX at the supratherapeutic 6.0 mg/kg dose level that is 4.9-9.8 fold higher than the standard 4-8 mg clinically applied dose levels for DEX (
Referring to
The best results were obtained with 6.0 mg/kg supra-therapeutic high dose DEX (HED: 0.49 mg/kg; 39 mg dose for an 80 kg person) (Mean±SE ALI score: 1.8±0.3;
As there was significant residual tissue damage in the lungs and liver of surviving LPS-GalN challenged mice treated with RJX or DEX (even at the supra-therapeutic dose 6.0 mg/kg dose level), it was next sought to determine if a combination of low dose RJX (0.7 ml/kg) and supratherapeutic high dose DEX (6.0 mg/kg) could improve the survival outcome and most importantly the tissue healing after LPS-GalN exposure. Treatments were initiated at 2 h after LPS-GalN injection at a time of documented active systemic inflammation. The combination therapy was more effective than RJX alone or DEX alone (
In contrast to the rapid death of all control mice treated with NS (Median survival: 4.3 h post LPS-GalN or 2.3 h after administration of NS), 100% of mice treated with RJX+DEX survived the LPS-GalN challenge (Median survival: >24 hours post LPS-GalN or >22 hours after initial administration of RJX+DEX) (
RJX+DEX effectively reversed the increased serum levels of the systemic inflammation markers (IL6, TNF-α, and LDH) within 24 h, and it appeared to be overall more effective than DEX alone or RJX alone (
The serum levels of LDH, a biomarker of systemic inflammation and tissue damage as significantly lower in mice treated with the RJX+DEX combination than mice treated with RJX alone (p<0.0001) or DEX alone (p<0.0001) (
The lung histopathological ALI scores ranged from 3 to 4 for the LPS-GalN+NS, from 2-3 for the LPS-GalN+RJX, from 1-3 for LPS-GalN+DEX, and from 1-2 for LPS-GalN+RJX+DEX. Hence, even when treatments were delayed until the onset of fulminant cytokine storm and systemic inflammation with severe oxidative stress as well as very severe lung damage, a near-complete recovery of the inflammatory lung injury was achieved within 24 h. Similar to its effects on the LPS-GalN induced ALI, RJX+DEX combination significantly reduced the liver injury (
The efficacy of a combination of low dose RJX (0.7 ml/kg) and standard dose DEX (0.6 mg/kg) was next evaluated. Treatments were initiated at 2 h after LPS-GalN injection at a time of documented active systemic inflammation. The outcome results obtained with DEX alone or RJX alone were inferior to those obtained with the RJX+DEX combination. In contrast to the rapid death of all control mice treated with NS (Median survival: 5.1 h post LPS-GalN or 3.1 h after administration of NS), 15 of 20 (75%) of mice treated with RJX+DEX survived the LPS-GalN challenge (Median survival: >24 h post LPS-GalN (
By comparison, the combined group of mice treated with monotherapy (i.e., RJX alone or DEX alone) (N=30) had a 24-h survival rate of 53% (i.e., 16 of 30 mice) (Monotherapy with RJX or DEX vs. Combination therapy with RJX+DEX: Log-rank X2=3.977, p=0.046).
Notably, delayed treatments with RJX+DEX starting at 2 h after the LPS-GalN injection reversed the lung damage, as evidenced by significantly reduced histopathological lung scores (
The tissue healing activity of the combination was more pronounced than the tissue healing activity of RJX alone or DEX alone (
COVID-19 has become a leading cause of death. Patients with high-risk COVID-19 are in urgent need of effective strategies that can prevent and/or reverse the systemic inflammatory process and its complications, including acute respiratory distress syndrome (ARDS) and multi-organ failure. DEX has been shown to improve the survival outcome of patients with ARDS. Furthermore, in the recently published open-label randomized “RECOVERY” trial, the use of DEX in hospitalized hypoxemic COVID-19 patients requiring invasive mechanical ventilation has been associated with improved survival outcomes. Similar findings were reported from other studies.
The composition, mode of action, and recently published favorable clinical safety profile of RJX make it an attractive anti-inflammatory drug candidate to prevent and treat sepsis.
IL-6, TNF-α, and TGF-ß are important pro-inflammatory cytokines that contribute to the pathophysiology of the cytokine release syndrome (CRS), ARDS and multi-organ failure in critically sick adult COVID-19 patients as well as children and adolescents with COVID-19 who develop a multi-system inflammatory syndrome (MIS-C). Recently, it was demonstrated that RJX prevents in the LPS-GalN mouse model of sepsis the marked increase of each of these cytokines in the serum as well as lungs and liver. Here, the combination of RJX plus DEX in therapeutic settings in a preclinical sepsis model was probed. The data provide preclinical proof regarding the clinical impact potential RJX and its combination with DEX to treat sepsis. Treatments with a combination of RJX plus DEX, when initiated after the onset of systemic inflammation and inflammatory organ damage post-injection of an invariably fatal dose of LPS-GalN, immediately reversed the inflammatory cytokine responses, reversed inflammatory organ damage in lungs and liver within 24 hours, and significantly improved survival.
The superiority of the combination regimen was particularly striking when comparing the histopathological data on sepsis-associated organ damage in lungs and liver from mice treated with monotherapy (RJX or DEX alone) vs. combination therapy. Notably, initiation of combination therapy after onset of the inflammatory cytokine responses and systemic inflammation resulted within 24 hours in a near-complete recovery of very severe organ damage in the lungs that was caused by LPS-GalN induced sepsis. It was hypothesized that RJX plus DEX will shorten the time to resolution of lung injury and viral sepsis in COVID-19 patients by preventing the development of a fulminant cytokine storm as well as reversing the cytokine-mediated multi-system inflammatory process and thereby mitigating the inflammatory organ injury. Furthermore, the demonstrated prevention of TGF-ß production in the lungs in RJX-treated mice, it was postulated that RJX alone or in combination with DEX may also help reduce the risk of pulmonary fibrosis after ARDS. RJX is currently being evaluated in hospitalized COVID-19 patients with viral sepsis to test the hypothesis that it will contribute to a faster resolution of respiratory failure and a reduced case mortality rate. A study has also been designed to determine if RJX plus DEX combination can reduce the mortality rate of severe to critical COVID-19.
The anti-sepsis activities of RJX, DEX, and RJX plus DEX were evaluated in the LPS-GalN model of fatal sepsis, as previously described. The research project was approved by the Animal Care and Use Committee of Firat University. Male BALB/c mice were randomly divided into different treatment groups using a pseudo-randomization convenience allocation to assign mice to identified cages. As in previous studies, we applied the concealment of treatment allocation and blind outcome assessment to reduce the risk of bias.
In order to induce fatal sepsis, mice were challenged with an i.p. injection of LPS plus D-galactosamine (Sigma, St. Louis, Mo.). Each mouse received a 500 μL i.p. injection of LPS-GalN (consisting of 100 ng of LPS plus 8 mg of D-galactosamine). Treatments were delayed until 2 hours post LPS-GalN injection when mice have a fulminant systemic inflammation with very severe lung and liver damage as well as markedly elevated inflammatory cytokine levels. Vehicle control mice were treated with 0.5 mL NS instead of RJX. NS was administered i.p 2 hours after LPS-GalN. Test mice received either RJX (0.7 ml/kg or 1.4 ml/kg) or DEX (0.1 mg/kg, 0.6 mg/kg or 6.0 mg/kg) as a monotherapy in a side-by-side comparison. Also examined was a combination of 0.7 mL/kg RJX with either 0.6 mg/kg or 6 mg/kg DEX at 2 hours post LPS-GalN injection. Drugs were administered i.p. in a total volume of 0.5 ml. The human equivalent dose (HED) level were determined as described. Mice were monitored for mortality for 24 h. The Kaplan-Meier method, log-rank X2 test, was used to analyze the 24 h survival outcomes of mice in the different treatment groups. At the time of death, lungs and liver were harvested, fixed in 10% buffered formalin, and processed for histopathologic examination. 3 μm sections were cut, deparaffinized, dehydrated, and stained with haematoxylin and eosin (H & E) and examined with light microscopy. Blood samples were collected at the time of death or termination and used for measurement of inflammatory cytokine and LDH levels, as reported.
Statistical analyses employed standard methods, including analysis of variance (ANOVA) and/or, nonparametric analysis of variance (Kruskal-Wallis) using the SPSS statistical program (IBM, SPPS Version 21), as reported. Kaplan-Meier method, log-rank X2-test, was used to investigate survival and fatality in each group.
Patients that are at risk of developing ARDS may be treated by a method herein. This example outlines treatment of 6 hospitalized adult patients (Age: 24-67 years) with high-risk COVID-19 who were at very high risk for development of hypoxemic respiratory failure and ARDS with a combination of RJX and Dexamethasone that was part of standard of care (in one patient Solumedrol was used instead of Dexamethasone as per the institutional standard of care).
Standard of care also included anti-coagulants, broad-spectrum antibiotics, remdesivir, and in one patient convalescent plasma. Each patient was on oxygen therapy because of a multi-focal bilateral COVID-19 pneomonia. Each patient had highly elevated serum markers for inflammation. RJX was used at a daily flat dose of 20 ml mixed with 100 mL normal saline (total volume of unfudate=120 mL). It was administered intravenously over 40 min. The weight of the patients ranged from 65.8 kg to 156 kg (65.8 kg, 90.7 kg, 102.8 kg, 105 kg, 118 kg, 156 kg; Median=104 kg). Hence, the dose of RJX varied from 0.3 mL/kg to 0.1 mL/kg.
Each of the 6 patients showed rapid recovery and were discharged from hospital within 3-7 days; no patient had to be re-admitted or experienced a worsening of their conditioning following their discharge. Patients were treated only while hospitalized and therefore they received 3-7 doses of RJX.
Three adult critically ill hospitalized COVID-19 patients with ages of 43 years, 60 years, and 70 years with hypoxemic failure due to advanced COVID-19 pneumonia and viral sepsis were treated with a combination of RJX and Dexamethasone that was part of standard of care. Standard of care also included anti-coagulants, broad-spectrum antibiotics, remdesivir.
Each patient was on high flow oxygen therapy and positive pressure ventilation because of a multi-focal bilateral COVID-19 pneomonia. Each patient had highly elevated serum markers for inflammation. RJX was used at a daily flat dose of 20 ml. It was administered intravenously over 40 min.
The weight of the patients ranged from 66.7 kg to 89.4 kg (66.7 kg, 77 kg, 89.4 kg; Median=77 kg). Hence, the dose of RJX varied from 0.3 mL/kg to 0.2 mL/kg and it was administered in a volume of 120 mL.
Each of these patients showed rapid recovery and were discharged from hospital within 7-14 days; no patient had to be re-admitted or experienced a worsening of their conditioning following their discharge. Patients were treated only while hospitalized and therefore they received 7 doses of RJX. Hence, treatment with RJX in combination with Dexamethasone-including standard of care reversed the viral sepsis.
Two lots of RJX were used: The percentages of ascorbic acid, thiamine HCl, cyanocobalamin, niacinamide, pyridoxin HCl, riboflavin 5′-Phosphate, calcium pantothenate, and magnesium sulfate were 8.981%, 0.625%, 0.019%, 1.193%, 1.200%, 0.025%, 0.028%, and 8.151% in Lot PPP-18-1031 and 9.011%, 0.643%, 0.019%, 1.186%, 1.191%, 0.025%, 0.028%, and 8.176% in Lot PPP-18-1051.
Studies were conducted in diabetic rats on a high-fat diet.

Study Design (N=100):
Wistar albino rats were randomly assigned to control (n=20) and diabetic wound groups (n=80). The rats in the control group underwent full-thickness skin resection in the back (size: 5 mm diameter, with depth to the fascial layer) and be treated by physiological saline, i.p. The rats in the diabetic wound groups were fed a high-fat diet for 4 weeks and then intraperitoneally injected with STZ (45 mg/kg) after being fasted for 16 h. The rat with fasting blood glucose ≥13.88 mmol/L or 250 mg/dl was considered as a successful model of diabetes (Chao et al., 2018).
After one week, a wound was made in the rat back (size and depth were the same as in the control group). These rats were further randomly assigned to 3 treatment groups (n=20/group; Table 2): (1) diabetic group (DM): induced diabetes, without RJX 0.5 ml/day i.p. normal saline as vehicle; (2) DM+RJX low group (DM+RJX-low): induced diabetes, with RJX-low dose (1.25 mL/kg/day RJX-P, i.p; 3) DM+RJX high group (DM+RJX-high): induced diabetes, with RJX-high dose (2.5 mL/kg/day RJX-B, i.p).
In diabetic group 1, vehicle control rats were treated with 0.5 mL normal saline (NS), i.e., an aqueous solution of 0.9% NaCl instead of RJX. NS (2.5 mL/kg/day) was administered intraperitoneally (i.p). On days 3, 7, 14, and 21, five rats in each group were randomly selected and terminated.
Specimen Collection and Processing
Wound healing was dynamically observed to calculate the healing rate. Wound healing rate=(original area-residual area)/original area×100%. On days 3, 7, 14, and 21, five rats in each group were randomly selected and were injected intramuscular injection of 85 mg/kg ketamine hydrochloride (Ketalar, Pfizer) and 6 mg/kg xylazine hydrochloride (Rompun, Bayer) anesthesia. Wound tissues in the model area were collected to conduct the pathological examination and biological examination.
Qualitative Examination of the Wound and Wound Area Measurements
The wound borders were marked on a transparent plastic film with a fine-tipped marker. The wound areas were measured by millimetric paper and planimeter. Beginning on the day wound contraction began, each examination measured the wound contraction rate, the fraction of the wound healed, and the expansion rate. Then, the day epithelialization has first noticed, the fraction of wound healed by epithelialization and the number of days it took for healing to occur were documented. Wound sizes wound area and wound contraction were determined.
Histopathological Examination
The full-thickness wounded skin tissue samples, including the adjacent skin, were photographed and then removed after sacrificing the rats on 3, 7, 14, and 21 days of treatment and subjected to histopathological examination. The tissue samples were fixed in 10% neutral-buffered formalin solution, embedded in paraffin wax, cut into 5-μm-thick sections made from the center of each wound, and stained with hematoxylin-eosin and Masson's trichrome stain, and examined by light microscopy. The histological scoring was assigned in a blinded manner as described previously (Table 3) (Celani et al., 2019).
Statistical Analysis
Statistical analysis includes analysis of variance (ANOVA) and/or, nonparametric analysis of variance (Kruskall-Wallis) using the statistical programs (IBM, SPPS Version 21 or/and GraphPad Prism version 8.0). Shapiro-Wilk test was performed for normality with a significance level of 0.05. If the data shows normally distribution (Shapiro-Wilk test result p≥0.05), a parametric analysis of variance (ANOVA) was performed. After that, a parametric analysis of variance (ANOVA) was performed and Tukey's multiple comparisons were used as a post hoc test to detect alterations among the groups. Independent samples T-test was used as pairwise comparisons for normally distribution two groups. If the ANOVA results were “not significantly different” (F test p≥0.05), the analysis stopped. If the data did not show normally distribution (Shapiro-Wilk test result p<0.05), a non-parametric analysis of variance (Kruskal-Wallis) was performed. If the Kruskal-Wallis test returned “statistically different” (p<0.05), the Dunn's multiple corporation test or Mann Whitney U test were performed to compare the values of the treatment groups to those of the vehicle/control group(s). If the Kruskal-Wallis test returned “not significantly different” (p≥0.05), the analysis stopped. p-values <0.05 were considered significant.
Referring
Compared with healthy rats used as controls, diabetic rats receiving NS as treatment (DM+NS) showed significantly delayed would healing as documented by significantly larger residual wound areas at the time points 7 days, 14 days and 21 days. Notably, treatment of diabetic rats with RJX significantly accelerated the wound healing in a dose-dependent manner. The wound healing in diabetic rats treated with 2.5 mL/kg RJX was even faster than the wound healing in untreated healthy rats.
Referring to
In agreement with the observed microscopic wound healing data, the histopathological wound healing scores based on micropscopic evaluations showed marked differences between NS treated vs. RJX treated diabetic rats, especially on days 7 and 14 confirming the accelerated wound healing with RJX treatment. Levels of re-epithelialization, granulation tissue formation, and collagen organization were higher in the rats of RJX-treated (particularly RJX 2.5 ip) groups compared to the diabetic control group treated with NS instead of RJX.
