Arch Biopartners' GMP Manufacturing of AB569 Progresses to Final Production Stage
TORONTO, ONTARIO--(Marketwired - Sept. 28, 2017) - Arch Biopartners, Inc., (Arch or the Company) (TSX VENTURE:ARCH)(OTCBB:ACHFF) today announced that the good manufacturing practice (GMP) production campaign for AB569 has advanced to the GMP glass vial filling stage.
AB569 is the Company's inhalation drug candidate for treating antibiotic-resistant bacterial infections in the lungs of cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD) patients as well as many other indications.
AB569 is a potential stand alone or complementary treatment to existing and emerging standard of care therapies for CF and COPD patients that have reduced lung function due to multi-drug resistant bacterial infections.
Manufacturing of AB569: update
AB569 is mainly composed of two compounds: ethylenediaminetetraacetic acid (EDTA) and sodium nitrite, which are already approved by the U.S. Food and Drug Administration (FDA) for use in humans in other medical applications.
The GMP manufacturing process and the terminal sterilized glass vial filling campaign for AB569 is being led by Dalton Pharma Services (Dalton). Dalton is initiating the GMP glass vial fill of three varying dose formulations of sodium nitrite followed by EDTA. These vials will then be packaged by Dalton into clinical drug kits to enable the start of the Phase I safety trial for AB569 at the Cincinnati Veterans Affairs Medical Center (CVAMC) at the end of this year or early January 2018.
Arch management intends to provide updates regarding the delivery date of the clinical drug kits to CVAMC and the start date of the Phase I safety trial as the glass vial filling stage nears completion.
Upcoming Phase I investigator Initiated Trial
CVAMC will conduct an investigator initiated Phase I human trial to evaluate the safety and pharmacokinetic profile of AB569.
Dr. Ralph Panos, Chief of Medicine at CVAMC and world-renowned COPD expert, is the lead investigator of the trial. Arch is funding the study, contributing the AB569 inhalation clinical drug kits produced by Dalton and other materials to support the trial.
Dr. Pano's clinical team will evaluate single administration of nebulized AB569 in normal participants. The Phase I trial has been designed to determine the pharmacokinetic profile of plasma nitrite and nitrate metabolites, exhaled nitric oxide and circulating hemoglobin after a single inhalation of AB569. In addition, the trial also aims to determine the tolerance of nebulized AB569 in three escalating doses of acidified sodium nitrite and EDTA.
Following the successful completion of the Phase I study, the clinical team at CVAMC in association with the University of Cincinnati College of Medicine will transition the AB569 program into a Phase II trial to test the drug treatment's efficacy in treating chronic Pseudomonasaeruginosa (P. aeruginosa) infections in COPD patients.
Background to AB569 for antibiotic resistant airway infections
AB569 was invented by Dr. Daniel Hassett, Professor at the University of Cincinnati College of Medicine, to treat antibiotic resistant bacterial lung infections, which is a significant problem for patients with either CF, COPD or ventilator associated pneumonia, as well as burn, diabetic and blast wounds. AB569 is also a candidate treatment for antibiotic resistant urinary tract infections and skin infections. The University of Cincinnati has exclusively licensed AB569 to Arch.
AB569 is a bactericidal compound and constitutes an innovative potential treatment for dealing with pulmonary bacterial infections, some of which are resistant to all 26 approved antibiotics in the United States. In pre-clinical studies, AB569 has demonstrated significant ability to kill many types of Gram-negative and Gram-positive bacteria.
P. aeruginosa affects the majority of adult CF patients and often infects patients from childhood onward. Arch has received orphan drug designation for AB569 from the FDA for the treatment of CF patients with P. aeruginosa infections. Arch has also received an orphan medicinal product designation from the European Medicines Agency for the general treatment of CF patients.
CF patients are predisposed to bacterial lung infections due to abnormal mucus production in the lungs and airways. In particular, P. aeruginosa infects 40% of CF patients between the ages of 6 and 10 years of age. By the age of 17, the frequency of infection increases to ~60% and reaches approximately 65% of all CF patients between the ages of 25 and 34.
The mucoid form of P. aeruginosa is a very challenging infection to treat due to its high resistance to both antibiotics and phagocyte-mediated killing. Once patients present with the mucoid form of P. aeruginosa, their overall lung function precipitously declines, resulting in a poor overall clinical prognosis.
Likewise, people with COPD have compromised innate immune systems and respiratory conditions that are vulnerable to chronic bacterial infections including P. aeruginosa that are often refractory to conventional antibiotic regimens.
COPD is a major health problem worldwide and its prevalence is increasing (over 325,000,000 patients world-wide), ranked by the World Health Organization as the third leading cause of death. COPD is a general term to describe progressive lung diseases which includes chronic bronchitis, emphysema, and non-reversible asthma. Most cases are caused by inhaling pollutants, predominantly from smoking or exposure to lung pollutants in highly polluted cities around the world as well as the workplace.
