Arch Biopartners Announces Metablok Achieves Primary Endpoints of Safety and Tolerability in Phase I Trial

TORONTO, Dec. 18, 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) has completed dosing of all scheduled volunteers and Metablok has met the primary endpoints of safety and tolerability. Metablok is the Company’s lead drug candidate for treating organ damage caused by inflammation.

Metablok was well tolerated during the placebo-controlled trial and no drug-related adverse effects were observed in any of the forty-four volunteers, split into five groups. Three of the groups received either a low, medium or high single dose of Metablok and the remaining two groups received a low or medium single daily dose over three days.

Arch is expected to close the trial over the next week with a database lock in early 2020. Final results and study reports will be released over the next 3 months.

During this time, Arch management will begin preparations to engage the U.S. FDA in discussion regarding a New Drug Application and Phase II trial for Metablok.

Metablok Phase I clinical trial

Arch has been conducting the Phase I clinical trial for Metablok with 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.

The successful Phase I trial is expected to be followed by a Phase II trial to investigate Metablok’s efficacy at preventing inflammation related acute kidney injury in patients undergoing cardiac surgery.

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.
