Arch Biopartners Announces Dosing of First Patient in Canada in the Phase II Trial for LSALT Peptide Targeting Cardiac Surgery Associated-Acute Kidney Injury

Arch Biopartners Inc., (“Arch” or the “Company”) (TSX Venture: ARCH and OTCQB: ACHFF), announced today that patient recruitment and dosing have begun in Canada for the Phase II trial for LSALT peptide targeting the prevention and treatment of cardiac surgery-associated acute kidney injury (CS-AKI).

The clinical team at the University of Calgary Cumming School of Medicine has started screening patients for the trial and has completed dosing of the first patient recruited into the study in Calgary, Alberta.

The University Health Network and Unity Health Toronto are also in the final stage of obtaining ethics and hospital approvals to start patient recruitment into the trial at Toronto General Hospital and St. Michael’s Hospital, respectively.

Quote from Richard Muruve, CEO, Arch Biopartners:

“We are happy to see the team at the University of Calgary Hospital recruit and dose the first patient in Canada for our Phase II study targeting CS-AKI. Our five clinical sites in Turkey have made good recruitment progress and have done a great job executing the trial to date. The start of recruitment in Calgary, followed by the activation into the study of the two Toronto hospitals, will significantly boost the momentum of the trial.”

About the CS-AKI Phase II Trial

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.

Details of the Phase II trial, titled “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.

CS-AKI and LSALT peptide

CS-AKI often results from ischemia-reperfusion injury (IRI), which restricts blood flow and oxygen to the kidney (ischemia), leading to kidney cell damage. When blood flow is restored (reperfusion), inflammation is triggered, exacerbating injury to the kidney. There is no therapeutic treatment available in the market today that prevents acute kidney injury of the type commonly experienced by on-pump cardiac surgery patients. In the worst cases of AKI, the kidneys fail, requiring kidney dialysis or kidney transplant for survival.

LSALT peptide is the Company’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 this 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 at the Company’s website.

Incidence of CS-AKI

Acute kidney injury (AKI) is a common complication, with an increased risk in patients undergoing coronary artery bypass grafting (CABG) and other on-pump cardiac surgeries. The reported prevalence of CS-AKI is up to 30%, and it is independently associated with higher morbidity and mortality rates.
