Reperfusion Injury

British Medical Journal Open publishes paper detailing the results of the international Phase II human trial for LSALT peptide targeting acute lung and kidney inflammation in hospitalized patients infected with SARS-CoV-2 virusPhase II findings previously disclosed support dipeptidase-1 (DPEP-1) as a relevant therapeutic target for diseases of the lung, kidneys and liver where inflammation plays a major role. New biomarker data from the pandemic Phase II trial, provides further scientific rationale for Arch to bring LSALT peptide into larger trials to inhibit DPEP-1 mediated organ inflammation. Arch is currently performing a Phase II human trial to support LSALT peptide as a first ever treatment for preventing cardiac surgery-associated acute kidney injury. TORONTO, March 18, 2024 (GLOBE NEWSWIRE) -- Arch Biopartners Inc., (“Arch” or the “Company”) (TSX Venture: ARCH and OTCQB: ACHFF), announced today that it has published a peer reviewed paper in the British Medical Journal Open (BMJ Open) detailing the results of the international Phase II human trial for LSALT peptide targeting acute lung and kidney inflammation in hospitalized patients infected with SARS-CoV-2 virus. LSALT peptide is a DPEP-1 inhibitor and the Company’s lead drug candidate for preventing and treating inflammation injury in the kidneys, lungs, and liver. The paper in BMJ Open describes the clinical highlights, outcomes and biomarker results of the study. The Phase II trial was an international, multicenter, randomized, double-blind, placebo-controlled, proof of concept study of LSALT peptide for the prevention of organ inflammation such as acute respiratory distress syndrome (ARDS) and acute kidney injury (AKI) in patients infected with SARS-CoV-2. The exploratory, adaptive trial was initiated in the early stages of the global pandemic to identify clinical signals of efficacy for LSALT peptide in the treatment of acute lung and kidney inflammation. The results of the Phase II trial provided first-ever evidence validating DPEP-1 as a mediator of organ inflammation and therapeutic target in humans. In addition, LSALT peptide was well tolerated with no safety issues related to the drug. New biomarker data for LSALT peptide was disclosed for the first time in the BMJ Open publication. An analysis of serum inflammatory biomarkers was performed from blood samples collected from study participants. Biomarkers analyzed which relate to organ inflammation included cytokines and chemokines such as IL-6, CXCL8, CXCL10, IL-1β and CCL7. Collectively, a greater proportion of inflammatory biomarkers decreased in patients receiving LSALT peptide compared with placebo. In particular, the reduction of CXCL10 in the LSALT peptide group versus the placebo group was statistically significant at the end of treatment. CXCL10 plays a role in facilitating leukocyte recruitment to various vascular beds including the lungs and kidneys. The reduction of CXCL10 and the other inflammatory biomarkers during LSALT peptide treatment is consistent with LSALT peptide’s mechanism of action as an inhibitor of DPEP-1 mediated leukocyte recruitment to the lungs and kidneys. The new data provides more scientific rationale for Arch to advance LSALT peptide to prevent leukocyte recruitment and organ inflammation for other indications, including a larger Phase II trial targeting cardiac surgery-associated AKI, which recently began recruiting patients. More information on the current trial can be found below and at clinicaltrials.gov Details of the results from the Phase II trial are reported in the peer-reviewed journal BMJ Open. The publication, titled “Multicenter, Randomized, Double-Blind, Placebo-Controlled, Proof of Concept Study of LSALT Peptide as Prevention of Acute Respiratory Distress Syndrome and Acute Kidney Injury in Patients Infected with SARS-CoV-2 (COVID-19)” by Somayaji et. al. can be found at the BMJ Open website. Quote from Richard Muruve, CEO of Arch Biopartners Inc.: “When the pandemic started and hospitals were filling up with patients with respiratory distress caused by inflammation, we postponed our plans to do a CS-AKI trial to urgently perform a Phase II trial to treat hospitalized COVID patients and reduce acute organ inflammation. Now that we have published our biomarker and clinical data from the trial, we are more confident today that inhibiting DPEP-1 mediated leukocyte recruitment to the kidneys, lungs and liver is a valid path toward first-ever treatments to prevent acute injury in these organs.” About the Phase II trial for LSALT Peptide in Pandemic Patients The Phase II trial was an international, multicenter, randomized, double-blind, placebo-controlled, proof of concept study of LSALT peptide for the prevention of organ inflammation such as acute respiratory distress syndrome (ARDS) and acute kidney injury (AKI) in patients infected with SARS-CoV-2. Six clinical sites located in Canada, United States, and Turkey participated in the Phase II trial in 2021. The composite primary endpoint of the Phase II trial reflected the severe effects often experienced by hospitalized patients in the early months of the pandemic and deemed appropriate for LSALT peptide’s novel mechanism of action in blocking consequential inflammation in the lungs, kidneys, and other organs. The exploratory study was designed to detect a clinical signal of efficacy and was not powered for statistical significance. Previously disclosed in December 2021 and included in the BMJ Open publication, there were no significant differences in adverse events between LSALT peptide and placebo treated patients. The study population of the Phase II trial did not have enough incidence of ARDS or AKI to detect a conclusion on these two particular clinical outcomes. In a secondary evaluation of patients on ventilation, despite being older by an average of 5 years, subjects in the LSALT peptide group demonstrated 22.8 ventilation-free days compared to 20.9 days in the placebo group in the unadjusted analysis at 28 days. “Ventilation” was defined as a need for high flow oxygen therapy (≥ 6L/min), non-invasive ventilation, mechanical ventilation, or extracorporeal membrane oxygenation (ECMO). In a post-hoc analysis adjusting for age, body mass index (BMI), and PaO2/FiO2 ratio (a measure of lung disease severity), the difference in ventilation-free days was 6.7 days favoring the LSALT peptide group compared to the placebo group. About Phase II trial for LSALT Peptide targeting CS-AKI Arch Biopartners is currently sponsoring a Phase II trial for LSALT peptide targeting cardiac surgery-associated acute kidney injury (CS-AKI). CS-AKI is often caused by ischemia-reperfusion injury (IRI) that reduces blood flow (ischemia) and thus oxygen in the kidney causing kidney cell damage. Once blood flow is restored to normal (reperfusion), inflammation is triggered and injury to kidney cells is exacerbated. In the worst cases of AKI, kidneys fail, leading to kidney dialysis or kidney transplant. At present, there are no therapeutic treatments available to prevent or treat CS-AKI or IRI. The CS-AKI Phase II trial is an international multi-center, randomized, double-blind, placebo-controlled study of LSALT peptide. The recruitment target for the trial is 240 patients. The primary objective of the trial is to evaluate the percentage of subjects with AKI within seven days following on-pump (heart-lung machine) cardiac surgery, defined by the KDIGO (Kidney Disease: Improving Global Outcomes) criteria. Details of the Phase II trial, entitled “Phase 2 Global, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of LSALT peptide for the Prevention or Attenuation of Acute Kidney Injury (AKI) in Patients Undergoing On-Pump Cardiac Surgery” can be viewed at clinicaltrials.gov. Recruitment of patients in the CS-AKI trial has begun in three hospital sites in Turkey with a hospital in Canada (University of Calgary) joining the trial last week. Additional sites are expected to be added in Turkey and Canada in the next few weeks. About LSALT Peptide LSALT peptide is a novel peptide drug candidate and DPEP-1 inhibitor. In August 2019, a scientific team led by Arch scientists Dr. Donna Senger and Dr. Stephen Robbins published a paper in the journal Cell describing a novel mechanism of action for organ inflammation. In the publication, DPEP-1 was identified, for the first time, as a major leukocyte (white blood cell) adhesion receptor on the lung, liver and kidney endothelium. DPEP-1 was also identified as the target of LSALT peptide, differing from typical anti-inflammatory drugs by targeting this novel adhesion receptor rather than targeting individual cytokines, of which there are many. The Cell publication, titled “Dipeptidase-1 is an adhesion receptor for neutrophil recruitment in lungs and liver” by Choudhry et. Al. can be found at the Cell journal’s website. LSALT peptide has been shown by Arch scientists and their collaborators to prevent ischemia-reperfusion injury to the kidneys in pre-clinical models (Video Link to pre-clinical proof of concept). Details of their findings were published in a Science Advances publication, titled “Dipeptidase-1 governs renal inflammation during ischemia reperfusion injury” by Lau et. al. and can be found at the Science Advances website. About Arch Biopartners Arch Biopartners Inc. is a late-stage clinical trial company focused on preventing inflammation and acute organ injury. The Company is developing new drug candidates that inhibit inflammation in the lungs, kidneys, and liver via the dipeptidase-1 (DPEP-1) pathway and are relevant for common injuries and diseases where organ inflammation is an unmet problem.

SAN DIEGO--( BUSINESS WIRE )--Revelation Biosciences Inc. (NASDAQ: REVB) (the “Company” or “Revelation”) a clinical-stage life sciences company that is focused on harnessing the power of trained immunity for the prevention and treatment of disease, announced today new preclinical data on the potential therapeutic benefit of Gemini for the prevention of acute kidney injury (AKI) that was presented at the International Conference on Advances in Critical Care Nephrology (AKI & CRRT 2024) taking place in San Diego on March 12-15, 2024. Gemini is the Company’s proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD®), a toll-like receptor 4 (TLR4) agonist, in development for prevention of AKI. A copy of the presentation and poster presented at the AKI and CRRT 2024 Conference can be found on Revelation’s website . Results from Bilateral Rat Model of Ischemia Reperfusion Induced AKI In a clinically relevant bilateral rat model of ischemia reperfusion (I/R) induced acute kidney injury (AKI), animals were dosed intravenously with PHAD at 0.07 or 0.35mg/kg at 24 hours and/or 48 hours prior to I/R surgery. In addition to clinical observation, rats were evaluated for markers of kidney function at 24 and/or 72 hours post-surgery, and markers of kidney damage at 72 hours post-surgery. In this model, Gemini pretreatment (0.35mg/kg) significantly: Preserved kidney function with a more rapid return to base line relative to untreated control animals, with statistically significant reductions in serum creatinine (p<0.01 at 24 hours, p<0.02 at 72 hours) and serum blood urea nitrogen (BUN) (p<0.02 at 72 hours). Reduced overall damage (necrosis) of the cortical (p<0.02) and medullary tubules (p<0.01) relative to the untreated group. Significantly reduced markers of local inflammation at 24 and/or 72 hours as measured by concentrations of urinary and serum c-reactive protein (CRP) (p<0.01) and IL-6 (p<0.05). Significantly reduced markers of cellular inflammation as observed via reduced neutrophilic inflammation with a single dose of 0.35mg/kg (p<0.02). The improved kidney function, reduced necrosis and reduced inflammatory biomarkers observed in this study are attributed to the immunostimulatory preconditioning effect of Gemini which includes strong upregulation of IL-10, a key cytokine responsible for resolution of inflammation. “These results demonstrate that Gemini has the potential to reduce tissue damage and improve kidney function in ischemic reperfusion induced acute kidney injury and potentially other inflammatory diseases,” said James Rolke, Chief Executive Officer of Revelation. “In addition to this, we are excited to have initiated our Phase 1 clinical study with Gemini in February 2024 and we look forward to starting studies in patients later this year.” About Gemini Gemini is a proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD®) for systemic administration. It is being developed for multiple indications including as a pretreatment to prevent or reduce the severity and duration of post-surgical infection (GEMINI-SSI program), and as pretreatment to prevent or reduce the severity and duration of acute kidney injury (GEMINI-AKI program). In addition, Gemini may be a treatment to stop or slow the progression of chronic kidney disease (GEMINI-CKD program). Revelation believes Gemini works through trained immunity, which redirects and attenuates the innate immune response to external stress (infection, trauma, etc.). Revelation has conducted multiple preclinical studies demonstrating the therapeutic potential of Gemini in the target indications. About Revelation Biosciences Inc.

Therapeutic treatment with Auxora shown to hasten the recovery of kidney function and improve survival in a rat model of acute kidney injury (AKI) Preclinical results are consistent with clinical observations made with Auxora, supporting the KOURAGE trial in patients with severe AKI that will start enrolling in 2Q 2024 LA JOLLA, Calif., March 13, 2024 /PRNewswire/ -- CalciMedica Inc. (CalciMedica or the Company) (Nasdaq: CALC), a clinical-stage biopharmaceutical company focused on developing novel calcium release-activated calcium (CRAC) channel inhibition therapies for acute and chronic inflammatory and immunologic diseases, last evening presented data from preclinical studies of Auxora™ in acute kidney injury (AKI) at the 29th International Acute Kidney Injury and Continuous Renal Replacement Therapy Conference (AKI & CRRT) in San Diego, CA. David Basile, Ph.D., Professor of Anatomy, Cell Biology and Physiology at Indiana University, gave an oral and poster presentation entitled "The Store-Operated Calcium Channel Inhibitor Auxora Improves Renal Function Following Ischemia-Induced Acute Kidney Injury in Rats." "At AKI & CRRT, Prof. Basile discussed the most recent preclinical study of Auxora in an acute kidney injury model that used a treatment regimen of three daily doses of drug started six hours after ischemic injury, which resembles the dosing in our clinical protocol. The positive results from this study build on prior preclinical data and indicate that inhibiting Orai1 activity in an AKI model improves kidney function," said Kenneth Stauderman, Ph.D., Founder and Chief Scientific Officer of CalciMedica. "In rats with ischemic kidney injury akin to Stage 2 AKI, Auxora was shown to provide nearly complete recovery of kidney function, as evidenced by improved glomerular filtration rate (GFR) at 72 hours after injury, while placebo-treated animals showed little improvement in GFR. In rats with kidney injury akin to Stage 3 AKI, the rats treated with placebo died while those on Auxora survived and showed modest recovery of GFR. We are excited as these studies support clinical observations of Auxora that suggest the drug may be beneficial for AKI patients." AKI is a serious acute critical illness and denotes a sudden reduction in kidney function, or the organ's ability to clean and filter the blood, that results from a complication of critical illness. These animal model studies support observations from CalciMedica's clinical trials, particularly CARDEA, the Company's Phase 2 trial in patients with severe and critical COVID-19 pneumonia, where AKI was a relatively common co-morbidity or a common sequela of the disease. Compared to placebo-treated patients, Auxora-treated patients in CARDEA had lower levels of key biomarkers associated with kidney injury, lower incidence of treatment-emergent AKI and reduced mortality in those patients with decreased kidney function at the time of treatment. Additionally, previous preclinical studies conducted by CalciMedica and others suggest that Orai1 activity contributes to the activation and infiltration of pro-inflammatory Th17 cells in the kidney, which is associated with the development of AKI. CalciMedica has also shown that the active ingredient in Auxora, zegocractin, inhibits release of IL-17, which is a key pro-inflammatory cytokine from Th17 cells. "As we initiate KOURAGE, our Phase 2 trial of Auxora in severe AKI patients with associated acute hypoxemic respiratory failure, we are encouraged to have additional supporting data showing that Auxora has beneficial activity in animal models of AKI," said Sudarshan Hebbar, M.D., Chief Medical Officer of CalciMedica. "Patients randomized in KOURAGE will have Stage 2 and Stage 3 AKI, so the results from Prof. Basile's recent preclinical study, most notably the survival benefit, are particularly meaningful. Severe AKI in the presence of respiratory failure has a mortality of approximately 50% and we are heartened to see that Auxora has the potential for a positive impact on patients with this devastating disease." Data Presented at the AKI & CRRT Conference The data presented at AKI & CRRT was from a series of studies referred to as Study 1 and Study 2. In Study 1, AKI was induced in a rat model through ischemia reperfusion injury (I/R), a transient ligation of the renal artery, while control animals underwent sham-surgery. Within 30 minutes of injury, the animals were treated with a single intravenous infusion of either 16 mg/kg of Auxora or placebo over a period of 4 hours. GFR, an important indicator of kidney function, was evaluated at 24 hours post-injury. Study 2 evaluated recovery of kidney function following I/R similar to Study 1 but varying in intensity to mimic different severity of disease. In Study 2, GFR was measured 2-4 hours after injury but before treatment, and treatment with 16 mg/kg of Auxora or placebo was administered at 6, 24 and 48 hours post-injury, with GFR again evaluated at 72 hours. Results from Study 1 showed that at 24 hours post-injury, GFR was significantly higher in rats treated with Auxora 30 minutes after injury versus placebo (61%, p<0.05). Additionally, animals treated with Auxora showed a reduction in Th17 cells in the kidney of approximately 50% as compared to those treated with placebo. In Study 2, in a group of animals with initial GFR reductions of approximately 50%, similar to Stage 2 AKI, GFR at 72 hours was significantly greater in Auxora-treated animals as compared to placebo-treated animals (0.81±0.03 vs. 0.47±0.04 ml/min/100g respectively; p<0.001). In a group of animals with GFR reductions ≥66%, similar to Stage 3 AKI, placebo-treated rats experienced 100% mortality by 72 hours while Auxora-treated rats had no mortality at 72 hours and were stable, showing modest recovery of kidney function. These results indicate that Auxora has the ability to hasten the recovery of kidney function and improve survival in rat models of AKI. About AKI Acute kidney injury (AKI) denotes a sudden reduction in kidney function, or the organ's ability to clean and filter the blood, as measured by increased serum creatinine (a cellular waste product) or decreased urine volume. AKI can result as a complication of critical illness such as sepsis, pneumonia and acute pancreatitis, and other causes such as trauma, surgery and burns. There are approximately 3.7 million patients hospitalized with AKI in the United States each year. The majority have Stage 1 AKI and recover with supportive care alone. However, approximately 1.1 million of these patients advance to Stage 2 and Stage 3 AKI, over half of whom have associated acute hypoxemic respiratory failure (AHRF). The risk of serious morbidities and mortality is significant for advanced Stage 2 and Stage 3 AKI patients. There are currently no approved therapies for AKI. About KOURAGE KOURAGE is a randomized, double-blind, placebo-controlled study that will evaluate 150 patients with Stage 2 and 3 AKI who have AHRF and are receiving oxygen by non-invasive mechanical ventilation, high flow nasal cannula or intermittent mandatory ventilation (IMV). Patients will be stratified by classification of stage of AKI as well as the use of IMV. Patients will receive either a four-hour infusion of Auxora or placebo at 1.25 mL/kg as a first dose, after which they will receive Auxora or placebo at 1.0 mL/kg at hours 24, 48, 72 and 96. The primary endpoint of the trial will be evaluation of patients through day 30 to determine days alive, ventilator-free and dialysis-free. Secondary endpoints will include a composite of: all-cause mortality, decrease in estimated glomerular filtration rate (eGFR), and the incidence of dialysis over a period of 90 days, also known as MAKE-90 (Major Adverse Kidney Events at 90 days). About Auxora™ CalciMedica's lead clinical compound, Auxora™, is a potent and selective small molecule inhibitor of Orai1-containing CRAC channels that is being developed for use in patients with acute inflammatory and immunologic illnesses. CRAC channels are found on many cell types, including immune system cells, endothelium cells and pancreatic acinar cells, where aberrant activation of these channels may play a key role in the pathobiology of acute and chronic inflammatory syndromes. Auxora is currently being evaluated in: (i) a Phase 2b trial for acute pancreatitis (AP) with accompanying systemic inflammatory response syndrome (SIRS), called CARPO, (ii) an investigator-sponsored Phase 1/2 trial, called CRSPA, being conducted in pediatric patients with asparaginase-induced pancreatic toxicity (AIPT) as a side effect of pediatric acute lymphoblastic leukemia treatment with asparaginase, (iii) a Phase 2 dose-ranging pharmacodynamic study in critical COVID-19 patients and (iv) a Phase 2 trial in AKI with associated AHRF, called KOURAGE, expected to initiate in the first half of 2024. There are currently no approved therapies to treat either AP, AIPT or AKI. In previous trials, patients responded well to Auxora regardless of severity or cause of disease. CalciMedica is also exploring the potential of Auxora treatment for other acute indications including acute respiratory distress syndrome. About CalciMedica CalciMedica is a clinical-stage biopharmaceutical company focused on developing novel CRAC channel inhibition therapies for inflammatory and immunologic diseases. CalciMedica's proprietary technology targets the inhibition of CRAC channels to modulate the immune response and protect against tissue cell injury, with the potential to provide therapeutic benefits in life-threatening inflammatory and immunologic diseases for which there are currently no approved therapies. CalciMedica's lead product candidate Auxora™, a proprietary, intravenous-formulated CRAC channel inhibitor, has demonstrated positive and consistent clinical results in multiple completed efficacy clinical trials. CalciMedica is currently conducting a Phase 2b trial for a planned 216 patients (called CARPO – NCT04681066) for AP with SIRS, with topline data expected in the first half of 2024, as well as supporting the ongoing Phase 1/2 CRSPA AIPT study (called CRSPA – NCT04195347), with additional data expected by 2H 2024. CalciMedica plans to initiate its Phase 2 KOURAGE study in AKI in 1H 2024.
