Arch Biopartners Announces Issuance of U.S. Patent for Metablok

TORONTO, CANADA–(Marketwired – Oct. 11, 2016) – Arch Biopartners, Inc., (Arch or the Company) (TSX VENTURE:ACH) (OTCBB:FOIFF) announced today the U.S. Patent and Trademark Office (USPTO) has issued U.S. Patent 9,464,114 titled, “Peptides that Block Leukocyte Recruitment and Methods of Use”.

This is the first patent issued protecting the composition and method of use for Metablok™, the Company’s drug candidate targeting inflammation, sepsis and cancer metastasis.

“This patent establishes Metablok as a leading commercial opportunity in the Arch portfolio and provides a clear path for human clinical trials” said Dr. Daniel Muruve, Chief Science Officer of Arch and Professor of Medicine at the University of Calgary.

Management of Arch believes Metablok has the potential to be a major breakthrough in the treatment of diseases where inflammation plays a major role, as well as in sepsis and cancer metastasis. Arch is currently pursuing further clinical development of Metablok and expects to make additional disclosures as milestones toward a human trial are completed over the next few months.

This patent is based on technology invented by Dr. Stephen Robbins, Dr. Donna Senger, Dr. Paul Kubes and Dr. Jennifer Rahn at the University of Calgary who previously assigned the intellectual property of Metablok to Arch.

About MetaBlok

Metablok is a drug candidate in the Arch development pipeline and a potential treatment for inflammation, sepsis and cancer metastasis.


Inflammation is a localized physical condition that involves the activation of the immune system in response to infection, tissue injury, or autoimmunity. Inflammation is involved in the pathogenesis of many diseases and contributes to organ dysfunction and failure.


Sepsis and cancer metastasis represent large unmet medical needs in the world today. Sepsis alone occurs in 1 to 2% of all hospitalizations in the US. It affects at least 700,000 individuals per year.

Sepsis is a serious illness caused by the body’s immune response to an infection. White blood cells, or leukocytes, defend the body against toxins and infection. If the immune system activates too many white blood cells to fight the infection, there is a risk of widespread, life threatening inflammation termed “Sepsis”.

Sepsis is known to cause organ damage. Blood clotting during sepsis inhibits blood flow to organs and thus reduces their intake of nutrients and oxygen. In severe cases, one or more organs fail. In the worst cases, infection leads to a dangerous drop in blood pressure, called septic shock. This can quickly lead to the failure of several organs such as lungs, kidneys and liver, causing death.

Permanent organ damage can occur in patients who survive sepsis. Under current standard of care, mortality rates are over 20% for sepsis and over 50% for septic shock.

Cancer Metastasis:

Cancer is a life threatening disease because of its ability to spread from its original tumour site to other tissues and organs in the body. This process of metastasis occurs through the bloodstream or lymphatic system.

Metastasis is of great importance since most of the cancer deaths are caused by spread of the primary cancer to other sites in the body. Recent evidence shows that 60% to 70% of cancer patients have started the metastatic process by the time of diagnosis. Additionally, patients that do not have tumor spread at diagnosis are at risk for metastatic disease. New therapeutic treatments that protect patients against metastasis would be a major breakthrough in the treatment of cancer.
