Arch Biopartners Expands Dosing in Phase I Trial for Metablok to Increase Dose Range for Future Phase II Studies

TORONTO, March 04, 2020 (GLOBE NEWSWIRE) — Arch Biopartners Inc., (“Arch” or the “Company”) (TSX Venture: ARCH and OTCQB: ACHFF) announced today that it is expanding the dose range of Metablok (LSALT peptide) for future Phase II trials targeting inflammation in the lung, the kidney and/or the liver by adding a cohort of eight healthy volunteers to receive the highest daily dose tested to date for three consecutive days.

Metablok is the Company’s lead drug candidate for treating organ damage caused by inflammation.

The three-day dosing of the additional eight volunteers will provide Arch supplemental dosing data, for review by the U.S. FDA, for its future Phase II trials. The expanded trial will allow an option of a higher dose of Metablok to potentially prevent or treat organ inflammation.

Dosing of the eight additional volunteers has begun and dosing is expected to end during March 2020.

The additional cohort of eight people has been added based on the successful dosing and safety of Metablok in the first 44 volunteers. To date, participants have received up to a high single dose of Metablok, or a low or medium daily dose over three days. In all cases, Metablok was well tolerated during the placebo-controlled trial and no drug-related adverse effects were observed.

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.

Metablok is an inflammation targeting drug and a potential therapeutic agent to prevent organ injury caused by sepsis and ischemia reperfusion injury. Metablok targets a novel neutrophil (white blood cell) adhesion molecule discovered by Arch scientists and reported in the journal Cell in September 2019.

A successful Phase I trial is expected to be followed by a Phase II trial to investigate Metablok’s efficacy at preventing inflammation in a vital organ. Arch is considering targeting inflammation related acute kidney injury in patients undergoing cardiac surgery as a first Phase II indication and/or a separate trial to target inflammation in the lungs caused by infection.
