Arch Biopartners Inc. Announces First Patient Successfully Dosed at Toronto General Hospital in Phase II Trial of LSALT Peptide Targeting Cardiac Surgery-Associated Acute Kidney Injury Arch Biopartners Inc. announced that the first patient has successfully completed dosing at Toronto General Hospital (TGH), part of the University Health Network (UHN), Canada's largest academic health sciences centre and a global leader in cardiac care and research. The volunteer patient completed five days of dosing as part of the Company's ongoing Phase II trial evaluating LSALT peptide to prevent and treat cardiac surgery-associated acute kidney injury (CS-AKI). TGH joins the University of Calgary Hospital as the second Canadian clinical site to dose patients in this trial. The Company anticipates St. Michael's Hospital (SMH) in Toronto will be the next Canadian site to activate and enroll patients into the study, pending approvals from Clinical Trials Ontario and SMH's ethics board. The Arch team continues to pursue additional clinical sites in Canada and the United States. Patient dosing completed in Turkey has provided a strong safety profile for LSALT peptide. This has given clinical trial teams increased confidence as new sites join the trial to test LSALT peptide's ability to protect kidneys from acute inflammation injury. The CS-AKI Phase II trial is an international, multi-center, randomized, double-blind, placebo-controlled study of LSALT peptide with a recruitment target of 240 patients. The start of the Phase II CS-AKI trial and the ongoing dosing of volunteer patients has been mainly supported through non-dilutive funding grants previously disclosed by the Company. The Company will update the study's listing on ClinicalTrials.gov following today's news regarding recruitment at Toronto General Hospital including a revised estimated trial completion date of August 2026. This update reflects the 12 to 18 months required by Canadian sites to complete preparations and obtain provincial and local ethics approvals prior to enrolling patients. The publication also reported notable biomarker findings: patients treated with LSALT peptide showed reductions in a range of inflammatory biomarkers, including a statistically significant decrease in CXCL10, a protein linked to inflammation in the lungs and kidneys. These results support continued clinical development for preventing inflammation injury in the kidneys, lungs and liver. Additional peer-reviewed publications related to LSALT peptide and the DPEP1 pathway are available on the Company's website. Incidence of CS-AKI: Acute kidney injury (AKI) is a frequent complication following cardiac surgery, especially in procedures that use a heart-lung machine.

Arch Biopartners Inc. Announces Start of Patient Recruitment in Phase II PONTIAK Trial Targeting Drug-Toxin-Related Acute Kidney Injury (AKI) Arch Biopartners Inc. announced that the investigator-led Phase II trial titled "Prevention OfephroToxin Induced Acute Kidney Injury with Cilastatin" (PONTIAK) has commenced patient recruitment at its primary clinical sites in Alberta, Canada. The Phase II PONTIAK study aims to evaluate the efficacy of cilastatin in preventing AKI associated with neephrotoxic pharmaceuticals, which include commonly used drugs such as antibiotics, chemotherapy agents, and imaging dyes, some of which are known to cause kidney damage as a side effect. The trial plans to enrol approximately 698 patients in five hospital sites in Alberta. The PONTIAK clinical team, based at the Universities of Calgary and Alberta, secured $1.5 million in funding for the Phase II trial from the Canadian Institutes of Health Research (CIHR), along with $400,000 under the Accelerating Clinical Trials (ACT) initiative aimed at evaluating Canadian biotechnologies using randomized controlled trials. Arch Biopartners recently manufactured the first-ever, stand-alone cilastatin drug product and has provided the drug supply for the trial. While the trial is investigator-led and independently funded, the Company is also evaluating opportunities to support a complementary arm of the study in another jurisdiction, such as the United States under an application to the U.S. Food and Drug Administration. AKI reflects a broad spectrum of clinical presentations, ranging from mild injury to severe injury that may result in permanent and complete loss of renal function. Clinically, the causes of AKI include sepsis,ischemia-reperfusion injury, and various endogenous as well as exogenous (drug) toxins. Cilastatin was approved for use as a fixed combination with imipenem to treat different types of bacterial infections. This fixed combination, approved by the FDA in 1985, is currently marketed under different names, including Primaxin®? (USA, UK, Australia, Italy), Tienam®? (Spain, Belgium), or Zienam®? (Germany). Composition of matter patents for imipenem and cilastatin have expired, and the combination drug is currently in a generic phase. Arch Biopartners owns and has exclusively licensed method-of-use patents to repurpose cilastatin as a new treatment targeting AKI. Annuncio • Apr 22

The clinical teams at Toronto General Hospital and St. Michael's Hospital in Toronto are now seeking final internal approvals and completing final preparations to begin patient recruitment in the first quarter of 2025. The trial continues to recruit patients at the University of Calgary Hospital and five clinical sites in Turkey. The CS-AKI Phase II trial is an international, multi-center, randomized, double-blind, placebo-controlled study of LSALT peptide with a recruitment target of 240 patients. The primary objective of the trial is to evaluate the percentage of subjects with acute kidney injury (AKI) within seven days following on-pump (heart-lung machine) cardiac surgery, as defined by the KDIGO (Kidney Disease: Improving Global Outcomes) criteria. Cardiac surgery-associated acute kidney injury (CS-AKI) is often caused by ischemia-reperfusion injury (IRI), which reduces blood flow (ischemia) and oxygen to the kidneys, causing kidney cell damage. When blood flow is restored (reperfusion), inflammation is triggered, exacerbating injury to the kidneys. Currently, no therapeutic treatment is available to prevent acute kidney injury (AKI) of the type commonly experienced by on-pump cardiac surgery patients. In severe cases of AKI, kidney failure occurs, requiring kidney dialysis or kidney transplant for survival. LSALT peptide is Arch's lead drug candidate for preventing and treating inflammation injury in the kidneys, lungs and liver. The drug targets the dipeptidase-1 (DPEP1) pathway and has been shown by Arch scientists and their collaborators to prevent IRI to the kidneys in pre-clinical models (video), providing the scientific rationale for Arch to use LSALT peptide in the current CS- AKI trial. Details of their findings were published in the journal Science Advances, titled Dipeptidase-1 governs renal inflammation during ischemia reperfusion injury by Lau et al. and can be found, along with the latest peer-reviewed publications about DPEP1 and LSALT peptide on the Company's website.

Arch Biopartners Inc. Announces its Cilastatin Drug Candidate to Participate in Pontiac Phase II Trial Targeting Acute Kidney Injury Caused by Drug Toxins Arch Biopartners Inc. announced that cilastatin, the Company’s second drug candidate for preventing acute kidney injury (AKI), will participate in the upcoming investigator led trial entitled Prevention Of NephroToxin Induced Acute kidney injury with Cilastatin (PONTIAC). PONTIAC is a 900 patient Phase II trial that will evaluate the efficacy of the dipeptidase-1 inhibitor cilastatin for preventing AKI caused by drugs such as antibiotics, chemotherapeutic agents and radiographic contrast. The PONTIAC clinical team of investigators, based out of the Universities of Calgary and Alberta, was awarded $1,500,000 by the Canadian Institutes of Health Research (CIHR) to fund the trial. The clinical team also received $400,000 as part of the Accelerating Clinical Trials (ACT) call for proposals to Evaluate Canadian Biotechnologies with Randomized Controlled Trials (October 2023). Funds from both grants will be used by the clinical team to conduct the PONTIAC trial. The PONTIAC clinical team sponsoring the trial is based in Calgary and is currently preparing to submit a Clinical Trial Application (CTA) to Health Canada to proceed with the trial by the fourth quarter of 2024. Arch is acting as a study partner for grant funding opportunities, providing cilastatin drug product and providing scientific and regulatory advice. Cilastatin is an enzymatic dipeptidase-1 (DPEP1) inhibitor approved by the FDA in 1985 for use as fixed combination with imipenem to treat different types of bacterial infections. Arch has method-of-use patents for repurposing cilastatin as a treatment for acute kidney injury (AKI) in several jurisdictions, including North America and Europe. There is no commercial history of cilastatin as a stand-alone drug product. The drug has a slightly different mechanism of action compared with Arch’s novel drug candidate, LSALT peptide (Metablok) a non-enzymatic DPEP1 inhibitor. Whereas LSALT peptide specifically blocks DPEP1-mediated inflammation in the kidney, lungs and liver, cilastatin has off target-effects that prevent toxin uptake in the kidneys. As such, cilastatin is particularly effective for toxin-related AKI. The PONTIAC trial builds on research published by lead Arch scientists and their colleagues in JCI (The Journal of Clinical Investigation) in 2018, when cilastatin was shown in pre-clinical models to effectively inhibit leukocyte recruitment and drug toxin uptake in the kidney, thereby preventing AKI caused by radiographic contrast. This provides Arch’s drug development program with a second target indication to prevent acute injury to the kidneys. The Company is currently dosing patients with its lead drug candidate, LSALT peptide, in an ongoing, international Phase II study targeting cardiac surgery-associated AKI (CS-AKI). Annuncio • Jul 31

Announces St. Michael's Hospital Joins the Phase II Trial of LSALT Peptide Targeting Cardiac Surgery Associated-Acute Kidney Injury Arch Biopartners Inc. announced that a research team from St. Michael’s Hospital, a site of Unity Health Toronto, has joined the Phase II trial for LSALT peptide targeting the prevention and treatment of cardiac surgery-associated acute kidney injury (CS-AKI). LSALT peptide is the Company’s lead drug candidate for preventing and treating inflammation injury in the kidneys, lungs and liver. The St. Michael’s Hospital clinical team is awaiting ethics approval prior to beginning enrolment in the trial. The addition of St. Michael’s as the third Canadian clinical site increases the number of trial sites to nine, with six hospitals in Turkey currently recruiting patients. 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. 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. There is no therapeutic treatment available in the market that prevents acute kidney injury of the type commonly experienced by on-pump cardiac surgery patients. LSALT peptide targets the dipeptidase-1 (DPEP-1) pathway and has been shown by Arch scientists and their collaborators to prevent IRI to the kidneys in pre-clinical models (video), providing the scientific rationale for Arch to use LSALT peptide in this CS-AKI trial. Incidence of Cardiac Surgery-Associated Acute Kidney Injury (CS-AKI) Acute kidney injury (AKI) is a known common complication in patients after coronary artery bypass grafting (CABG) and other cardiac surgeries, including on-pump surgeries which increase the risk of AKI. The reported prevalence of CS-AKI is up to 30% and is independently associated with an increase in morbidity and mortality. Annuncio • Apr 05
Anesthesia Clinical Trials Unit Joins the Phase II Trial of LSALT Peptide Targeting Cardiac Surgery-Associated-Acute Kidney Injury Arch Biopartners Inc. announced that Anesthesia Clinical Trials Unit (ACTU), an academic research organization in the Department of Anesthesia and Pain Management at the University Health Network (UHN), has joined the Phase II trial for LSALT peptide targeting the prevention and treatment of cardiac surgery-associated acute kidney injury (CS-AKI). LSALT peptide is the Company's lead drug candidate for preventing and treating inflammation injury in the kidneys, lungs and liver. The UHN clinical team has submitted an application to the local ethics board for permission to participate in the trial. The addition of UHN as the second Canadian hospital site increases the number of trial sites to eight, with six active clinical sites in Turkey. 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.

Arch Biopartners Clinical Team Publishes Data from Phase II Trial for Lsalt Peptide Targeting Organ Inflammation in Hospitalized Patients Infected with Sars-Cov-2 Arch Biopartners Inc. announced 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-1ß 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.
