Broward Health Medical Center Becomes First Clinical Site in U.S. for Phase II Trial for LSALT Peptide

TORONTO, July 28, 2020 (GLOBE NEWSWIRE) — Arch Biopartners Inc. (“Arch” or the “Company”) (TSX Venture: ARCH and OTCQB: ACHFF), a clinical stage company developing new drug candidates for treating organ damage caused by inflammation, today announced that it has chosen its first U.S. clinical site for the Phase II trial of its lead drug LSALT peptide (Metablok).  Broward Health Medical Center (BHMC) in Florida has agreed to participate in the trial and begin enrolling patients following internal review board approval, which is expected during the month of August.
The Phase II trial will be a multicenter, randomized, double-blind, placebo-controlled, proof of concept study of LSALT peptide as prevention of organ inflammation known to trigger acute respiratory distress syndrome (ARDS) and acute kidney injury (AKI) in patients infected with SARS-CoV-2 (COVID-19). BHMC will be among other hospitals in the United States, and elsewhere, that will enroll a total of sixty patients into the trial.The composite primary endpoint of the phase II trial reflects the severe effects often experienced by hospitalized COVID-19 patients and deemed appropriate for LSALT peptide’s novel mechanism of action in blocking consequential inflammation in the lungs and kidneys.The Phase II results will be used to design a larger Phase III trial, including patient numbers and optimal drug dosing. The completion of the current phase II trial will depend on the ongoing COVID-19 outbreak and number of hospitalized patients at risk of ARDS and AKI.About COVID-19COVID-19 is the disease caused by the novel coronavirus SARS-CoV-2 that emerged in China in late 2019. Severe complications from COVID-19 are in large part due to excessive host immune responses to the virus that result in progressive lung inflammation and acute respiratory distress syndrome that often requires mechanical ventilation and critical care¹. Patients with severe COVID-19 also experience multiple organ dysfunction including acute kidney injury, liver dysfunction, cardiac failure, and blood abnormalities. Currently, no approved vaccine or effective antiviral drug exists for SARS-CoV-2. Treatment of severe COVID-19 has been primarily supportive, relying heavily on respiratory, infectious disease and critical care medicine.Survival rates and health care system capacity could both be improved with new treatments that prevent the severe manifestations of COVID-19, such as worsening lung inflammation (ARDS) and AKI experienced by patients infected with SARS-CoV-2.¹ J. S. Ayres, Sci. Adv 10.1126/sciadv.abc1518 (2020)About Arch BiopartnersArch Biopartners Inc. is a clinical stage company focused on the development of innovative technologies that have the potential to make a significant medical or commercial impact.  Arch is developing a pipeline of new drug candidates that inhibit inflammation in the lungs, liver and kidneys via the dipeptidase-1 (DPEP-1) pathway for multiple medical indications.Metablok (LSALT peptide) is a novel peptide drug candidate and the lead DPEP-1 inhibitor in the Arch development pipeline. 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 in pre-clinical models. LSALT differs from typical anti-inflammatory drugs by targeting this novel adhesion receptor rather than targeting individual cytokines, of which there are over 30 currently known.A total of 40 out of 52 healthy, normal volunteers received Metablok during the recent placebo-controlled Phase I human trial. In all cases, Metablok was well tolerated during the trial and no significant drug-related adverse effects were observed.Continuing under development in the Arch portfolio are: AB569, a potential new treatment for antibiotic resistant bacterial infections in the lung and wounds; and, ‘Borg’ peptide coatings that increase corrosion resistance and decrease bacterial biofilm on various medical grade metals and plastics.For more information on Arch Biopartners, its technologies and other public documents Arch has filed on SEDAR, please visit www.archbiopartners.comThe Company has 60,782,302 common shares outstanding.Forward-Looking StatementsAll statements, other than statements of historical fact, in this news release are forward looking statements that involve various risks and uncertainties, including, without limitation, statements regarding the future plans and objectives of the Company.
