Arch Provides Interim Update on Phase I Trial for Metablok (LSALT Peptide)

TORONTO, Nov. 07, 2019 (GLOBE NEWSWIRE) — Arch Biopartners Inc., (“Arch” or the “Company”) (TSX Venture: ARCH and OTCQB: ACHFF) announced today that the Phase I human trial of Metablok (LSALT peptide), the Company’s lead drug candidate for treating organ damage caused by inflammation, has met the primary endpoints of safety and tolerability in the trial’s three single ascending dose cohorts of healthy volunteers.

To date, twenty-eight of forty-four planned volunteers for the trial have received either a low, medium or high single dose and no adverse effects were observed post-dosing.

Consequently, testing Metablok in 3-day, multiple ascending dose cohorts of eight volunteers per cohort has already begun. This second part of the study, representing the expected dosing schedule for the Phase II trial, is expected to be completed by the end of November. At that time, Arch plans to provide a further update.

Metablok Phase I clinical trial

Arch has been conducting the Phase I clinical trial for Metablok with 44 healthy volunteers in Melbourne, Australia. The Phase I trial is a double-blind, placebo-controlled, randomized, single and multiple ascending dose study to evaluate the safety and pharmacokinetic profile of Metablok.

A successful Phase I trial is expected to be followed by a Phase II trial to investigate Metablok’s efficacy in a 3-day treatment regime aimed at preventing inflammation-related acute kidney injury in cardiac surgery patients.

Cardiac Surgery-Associated Acute Kidney Injury

Acute kidney injury (AKI) represents an additional challenge for patients recovering from cardiac surgery. AKI occurs in approximately 30% of patients that undergo cardiac bypass surgery with approximately 5-7% of patients requiring dialysis. For patients who recover from the need for dialysis or mild AKI, there is a greater likelihood of developing chronic kidney disease in future than those who did not have AKI.

Currently, no specific therapies exist to prevent AKI. Worldwide, there are over one million patients per year that have cardiac surgery procedures.

Inflammation is known to contribute to AKI related to ischemia-reperfusion and other insults to the kidney that may occur in the course of cardiac surgery.

Metablok is a novel therapeutic agent that may protect the kidneys and prevent AKI in patients undergoing cardiac surgery.
