MONTREAL and BOZEMAN, Mont., Jan. 12, 2021 /CNW/ – 5N Plus Inc. (“5N Plus”), a leading global producer of specialty chemicals and engineered materials, and Microbion Corporation (“Microbion”), a clinical-stage pharmaceutical company focused on the development of compounds for the treatment of resistant and difficult-to-treat infections, jointly announced today that the parties have entered into a strategic relationship for the development, manufacturing and commercial drug substance supply of Microbion’s new class of antibiotic and antibiofilm drugs. Under the terms of the agreement, 5N Plus has taken an equity stake in Microbion and will assume responsibility for the manufacturing of Bismuth-based Active Pharmaceutical Ingredients (API) required in Microbion’s family of drug products currently under development, including the company’s lead API, pravibismane. Microbion retains responsibility for the development, manufacturing and commercialization of the final drug products currently under development.

In recent years, effective treatments for bacterial infections have become ever more critical, as some bacteria have become increasingly resistant to existing drug therapies. Microbion’s approach has been to develop a new class of microbial bioenergetic inhibitors that arrest the activities of a broad range of offending pathogens. Pravibismane, the first in this new class of anti-infectives, has demonstrated impressive antibacterial and antibiofilm activity against a wide range of Gram-negative and Gram-positive pathogens, including multiple priority pathogens or “superbugs” as identified by the US Centers for Disease Control and Prevention (CDC). As the world’s leading producer of Bismuth-based API compounds, 5N Plus is uniquely positioned to support Microbion in the development of this new class of compound. In the initial phase of the collaboration between the two companies, 5N Plus will be supporting Microbion’s clinical development programs.

Pravibismane suspension for topical/local administration is currently in Phase 2 for the treatment of diabetic foot ulcer infections and orthopedic-device infections. Inhaled pravibismane is in late pre-clinical studies for the treatment of chronic lung infections. The inhaled pravibismane program is receiving up to US$17.1M in non-dilutive development funding support from CARB-X (Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator) and the Cystic Fibrosis Foundation, as previously announced by Microbion. Microbion Corporation has closed a Series A financing of US$25M from GHS Fund (Quark Venture LP and GF Securities). Developing pravibismane for targeted, localized administration provides not only the ability to treat specific areas of severe unmet medical need, but also is an approach that can result in significant commercial opportunity within the anti-infectives field.

Mr. Paul Tancell, Executive Vice President of Eco-Friendly Materials at 5N Plus, commented: “We are delighted to be able to support Microbion in their journey to develop a much-needed class of new antibacterial drugs. Whilst there remains more development ahead of us, the initial results are simply impressive, with pravibismane indicating both a high level of antibacterial activity and that of patient safety.” Mr. Tancell added: “We will support Microbion with our wide expertise in the development and production of Bismuth-based APIs as they move through the clinical trials to registration”. Mr. Tancell concluded: “The potential market for pravibismane is significant and we are well positioned to benefit from the growth of this market.”

Mr. Karim Lalji, Chairman of Microbion Corp. and CEO of Microbion Pharma Corp., commented: “We are pleased with the development and supply partnership entered into with 5N Plus as we recognize their team as leaders in Bismuth-based material manufacturing. We will be working closely with 5N Plus to develop methods to efficiently and cost-effectively manufacture pravibismane. Furthermore, their purchase of an equity stake of the company further validates the potential promise of pravibismane and Bismuth-based compounds to treat a variety of serious, chronic infections for the betterment of patients.”

About Microbion
Microbion is a clinical-stage biopharmaceutical company developing pravibismane as the first product in a new class of anti-infective drugs with a mechanism of action that functions as a microbial bioenergetic inhibitor for the local treatment of antibiotic-resistant and difficult to treat infections. Pravibismane has antibacterial efficacy against a broad spectrum of pathogens, including multiple priority pathogens or “superbugs” identified by the US CDC. In addition to antibacterial efficacy, pravibismane has also demonstrated the ability to eradicate microbial biofilms. This dual antimicrobial action may offer a much-needed, novel clinical approach to treat infections. Microbion has been granted QIDP and Fast Track designations for multiple indications and Orphan Drug Designation for the treatment (management) of pulmonary infections in patients with cystic fibrosis by the US FDA. In addition, Microbion has completed two clinical trials of pravibismane in diabetic foot ulcer (DFI) and orthopedic implant-related infections and is continuing the clinical advancement of pravibismane for these indications. The International Nonproprietary Name (INN) recommended by the WHO of pravibismane is the first member in the bismane class which represents a novel class of anti-infective drugs. Microbion Corporation has previously closed a Series A financing of US$25M from GHS Fund (Quark Venture LP and GF Securities). For more information visit: www.microbioncorp.com.
