CARB-X funds Microbion to develop inhaled drug to treat cystic fibrosis-related lung infections

Microbion’s pravibismane anti-infective also wins funding from Cystic Fibrosis Foundation

(BOSTON) – CARB-X announced today it is awarding Microbion Corporation of Bozeman, MT, USA, up to $6.1 million plus up to $5.4 million more if certain project milestones are met, to develop its anti-infective drug pravibismane for the treatment of cystic fibrosis (CF)-related pulmonary infections.

The research project is CARB-X’s first award for the development of an inhaled antibiotic to treat chronic lung infections and potentially infections in people living with CF.

“Microbion’s new class of anti-infective represents a novel drug that has shown potent activity against antibiotic-resistant bacterial pathogens and the biofilms these pathogens produce. Microbion’s pravibismane, if successful and eventually approved for use in patients, has the potential to be a critical new weapon in the fight against chronic and resistant infections,” said Erin Duffy, Chief of Research and Development of CARB-X.

The funding from CARB-X, along with a separate award announced today of up to $5.6 million from the Cystic Fibrosis Foundation, will help Microbion further explore the potential of pravibismane to kill drug-resistant bacteria and their biofilms and test its safety as an inhaled treatment for people with CF. If the results are positive, the anti-infective could next move into clinical development to test its effectiveness.

People with CF are susceptible to chronic infections due to abnormally thick, sticky mucus in their lungs which traps bacteria in the airways. These bacteria often form colonies surrounded by a protective outer layer known as biofilms, a community of bacteria that adheres to surfaces and is able to cause chronic infections. Biofilms tend to allow bacteria to both evade the immune system and become more resistant to antibiotics. At least 80 percent of infections involve bacteria that have formed biofilms, according to the National Institutes of Health, making biofilms an important target when fighting hard-to-treat infections.

Karim Lalji, Microbion’s Chairman, said: “Beyond their investment, these organizations’ expertise in antibiotic-resistant infections, particularly those associated with CF, will prove valuable to advancing our technology as part of a much-needed solution to address the chronic and intractable infections that are a hallmark of CF.”

In laboratory tests, Microbion’s drug candidate pravibismane was shown to kill drug-resistant bacteria and their biofilms, including those that pose a higher risk for people with CF such as multi-drug resistant Pseudomonas aeruginosa and nontuberculous mycobacteria (NTM).

The US Food and Drug Administration (FDA) has given the project Orphan Drug Designation, as well as Qualified Infectious Disease Product (QIDP) and Fast Track designations for inhaled pravibismane for the treatment (management) of pulmonary infections in patients with cystic fibrosis. Cystic fibrosis lung disease, estimated to affect more than 30,000 in the US and 70,000 worldwide, is characterized by infection and severe inflammation that lead to progressive deterioration in lung function. The disease represents a major health-care burden, responsible for reduced quality of life, morbidity, and premature mortality.

Supporting innovation to address the global superbug crisis

The CARB-X portfolio is the world’s largest and most diverse antibacterial development portfolio with 40 active projects – antibiotics, vaccines, rapid diagnostics and other life-saving products – in five countries focused on addressing the global rise of drug-resistant bacteria.

CARB-X, led by Boston University and funded by a global partnership, is investing up to $500 million between 2016-2021 to support the development of new antibiotics, rapid diagnostics, vaccines and other life-saving products that address drug-resistant bacteria.  The goal is to support projects through the early phases of development – from hit-to-lead through Phase 1 for therapeutics – so that they will attract additional private or public support for further clinical development and approval for use in patients.

Since its launch in 2016, CARB-X has announced 62 awards exceeding $235.7 million, with the potential of additional funds if project milestones are met, to accelerate the development of antibacterial products. These funds are in addition to investments made by the companies themselves. The CARB-X pipeline will continuously evolve, as projects progress and others fail for a variety of reasons.

The CF Foundation’s commitment to antibiotic development

In 2018, the CF Foundation dedicated $100 million through 2023 to their Infection Research Initiative  as part of a sweeping effort to advance infection research. Currently, the CF Foundation is funding 12 new industry programs to develop treatments for CF-related infections.

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 is advancing pravibismane in clinical trials for two other infectious 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.
