ARCH Arch Biopartners Inc

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 it has completed enrollment for its Phase II study of Metablok (LSALT Peptide), targeting acute lung injury and acute kidney injury caused by inflammation in patients with severe cases of COVID-19. The Company expects to announce results in July 2021.

A total of 65 patients were randomized into the double-blind, placebo-controlled trial and 61 of these patients received at least one treatment dose.

“We would like to thank all of the patients and their families, as well as our clinical site teams in Canada, Turkey and the USA, for helping us achieve our patient enrollment target for this Phase II trial,” said Richard Muruve, CEO of Arch Biopartners.

About the Phase II trial for LSALT Peptide

The Phase II trial is an international, multicenter, randomized, double-blind, placebo-controlled, proof of concept study of LSALT peptide (Metablok) 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) or new variants of the virus. ARDS is the leading cause of death in COVID-infected patients. AKI has been observed in approximately 35% of patients admitted to hospital with COVID-19 and is also a leading cause of mortality.1

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, kidneys, and other organs.

Additional information about the Phase II trial can be found at:

The Phase II results will be used to design the Phase III program, including greater patient numbers, to more fully evaluate efficacy and safety in hospitalized patients at risk to inflammation in the lungs, kidneys or liver.

About COVID-19

COVID-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. Treatment of severe COVID-19 has been primarily supportive, relying heavily on respiratory, infectious diseases, 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-22 or the many variants that have emerged globally in recent months.

About Metablok (LSALT peptide) and DPEP-1

Metablok (also known as LSALT peptide) is a novel therapeutic agent and the lead DPEP-1 inhibitor in the Arch development pipeline.

A scientific team led by Arch scientists Dr. Donna Senger and Dr. Stephen Robbins first described a novel mechanism of action for organ inflammation in the journal Cell in August, 2019. In the publication, the enzyme DPEP-1 was identified for the first time as a major neutrophil adhesion receptor on the lung, liver and kidney endothelium. Their findings identified DPEP-1 as a novel therapeutic target for diseases of these organs where inflammation plays a major role.

About Arch Biopartners

Arch 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.

Continuing under development in the Arch portfolio are: AB569, a potential new treatment for antibiotic resistant bacterial infections in wounds and the lungs; and, ‘Borg’ peptide coatings that increase corrosion resistance and decrease bacterial biofilm on various medical grade metals and plastics.
