Microbion Corporation Announces Data Highlighting Pravibismane’s Effect on Bacterial Energetics Presented at ASM Microbe 2022

BOZEMAN, MT. and VANCOUVER, BC. October 11, 2022 – Microbion Corporation today announced that the company presented a poster highlighting the effect of pravibismane on bacterial energetics in Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli and Mycobacterium avium species at ASM Microbe 2022 in Washington, DC. The objectives of these studies were to further understand the mechanism of action of pravibismane, in both planktonic and biofilm phenotypes. Financial support for this study was provided by CARB-X.

The poster, titled “Pravibismane’s Effect on Bacterial Energetics is Conserved Across Various Bacterial Species” highlights that:

 • Pravibismane disrupts bacterial bioenergetics and protein synthesis in planktonic and biofilm phenotypes, contributing to pravibismane’s antimicrobial efficacy.

Pravibismane is the first in a new class of anti-infective drugs structurally unrelated to other clinically utilized antibiotics. With a novel mechanism of action, pravibismane rapidly reduces bacterial ATP production in both planktonic and biofilm bacterial populations, thereby halting global bacterial cellular metabolism. To our knowledge, this is the first example of an anti-infective drug candidate with a demonstrated MOA disrupting energy availability in bacteria, which is responsible for the ability to eradicate established biofilms of E. coli and P. aeruginosa. Pravibismane exhibits broad-spectrum, potent in vitro activity against chronic respiratory infection and chronic wound relevant pathogens and their biofilms including NTM, multidrug resistant P. aeruginosa and MRSA. Pravibismane has also demonstrated safety in multiple clinical studies including treatment of patients with diabetic foot infections and patients with serious orthopedic device-related infections. Several positive signals of efficacy (not statistically significant) were appreciated in these early clinical studies.

About Microbion 

Microbion is a clinical-stage pharmaceutical company developing a new class of therapeutic compounds to improve the lives of patients with rare and serious diseases. Microbion’s lead drug candidate, pravibismane, is the first product in this new class and has a novel mechanism of action offering unique potential to address the unmet needs of chronic and severe health conditions. The Company is advancing inhaled pravibismane in Phase 1 clinical development for the treatment of chronic lung diseases, including non-tuberculous mycobacteria (NTM) and cystic fibrosis-related lung infections. Topical/local pravibismane is in Phase 2 development for the treatment of chronic wounds and orthopedic infections. Pravibismane has received backing from the Cystic Fibrosis Foundation, NIH, US DoD, and CARB-X with over $21 million in grants. The FDA has granted pravibismane with Orphan Drug, Fast Track, and QIDP designations.
