CARB-X funds Peptilogics to develop a new class of antibiotics to treat serious superbug infections associated with implants

CARB-X funds Peptilogics to develop a new class of antibiotics to treat serious superbug infections associated with implants

Peptilogics’ engineered cationic antibiotic peptide is designed to kill multi-drug-resistant bacteria rapidly, transforming the way prosthetic joint infections (PJI) are treated 

(BOSTON) – CARB-X is awarding Peptilogics, headquartered in Pittsburgh, USA, up to US$2.56 million in non-dilutive funding to develop a new class of peptide antibiotics with broad activity against drug-resistant bacteria.  The company could receive up to $9.61 million more in additional funding if the project achieves certain development milestones, for a potential total of up to $12.17 million.

The initial application of the new antibiotic would be towards serious infections associated with implants such as prosthetic knees and hips. CARB-X funding will support the development of Peptilogics’ lead compound PLG0206, including the filing of a US Food and Drug Administration (FDA) Investigational New Drug (IND) Application and Phase 1 clinical trial.

“Joint replacements are an increasingly common surgical procedure, and infections are the most serious and costly complication of joint replacements,” said Erin Duffy, Chief of Research and Development of CARB-X, which is based at Boston University School of Law. “The Peptilogics project has exhibited activity against critical ESKAPE pathogens. The project is still in the early phases of development, but if successful and approved for use in patients, it could represent tremendous improvement in the treatment of periprosthetic joint infections.”

The number of joint replacements around the world is growing every year as the population ages. In the US alone, more than 1 million total joint replacements are performed annually, a number expected to grow to 4 million procedures by 2030, according to a study for the American Academy of Orthopaedic Surgeons, with similar trends observed in the European Union and Asia Pacific region. Following joint replacement, an estimated one to two percent  of patients develop infections. Currently, there are few treatment options and major surgery is required to attempt to resolve the infection.  Current standard of care PJI treatment has a high failure rate, is costly, and often requires additional follow-on surgical interventions, including complete replacement of the prosthesis. These additional procedures lead to substantial morbidity and mortality, with a 20 percent 5-year mortality risk, according to recent studies.

Jonathan Steckbeck, Founder and CEO of Peptilogics, said: “These funds will support further development of PLG0206, our lead compound that has demonstrated broad-spectrum activity against pathogens identified by WHO and CDC as critical, urgent, or high priority targets. We are honored to be partnering with CARB-X in working to address the current crisis in drug-resistant infections, which we believe is one of the most serious and acute issues affecting modern medicine and global public health.”

PLG0206 was developed with Peptilogics’ novel peptide design platform, using a proprietary algorithmic process to optimize activity characteristics, leading to a good safety profile in animals and potent broad-spectrum antibacterial activity against clinically-important MDR Gram-positive (Staphylococcus aureus, including MRSA, and Enterococcus faecium, including VRE) and Gram-negative (Pseudomonas aeruginosa, Escherichia coli, and Acinetobacter baumannii) pathogens.   In addition, PLG0206 exhibits the ability to disrupt biofilms, making it an ideal candidate for treatment of biofilm-associated infections.  PLG0206 sterilized implant materials following a short exposure in a biofilm model, suggesting that it could rapidly kill implant-associated biofilm bacteria in a clinical setting.

Peptilogics’ program has been granted Qualified Infectious Disease Product (QIDP) status by the FDA, which provides certain incentives for the development of new antibiotics, including an additional five years of market exclusivity, as well as eligibility for Priority Review and Fast Track designation.

Supporting innovation to address the global superbug crisis  
CARB-X is led by Boston University and funded by a global partnership. CARB-X is investing up to $500 million between 2016-2021 to support the development of new antibiotics, rapid diagnostics, vaccines and other life-saving products.  The goal is to support projects through the early phases of development – 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.

The CARB-X portfolio is the world’s largest antibacterial development portfolio with 38 active projects in five countries. Since its launch in 2016, CARB-X has announced 58 awards exceeding $195.6 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.

About Peptilogics
Peptilogics is a clinical-stage biotechnology platform company discovering and developing novel peptide therapeutics for critical unmet medical needs. The company’s first focus is to provide solutions for the current crisis of drug-resistant bacterial infections, which kill more than 700,000 people globally each year, according to a 2016 United Kingdom government study. Peptilogics’ anti-infective program focuses on compounds derived from their proprietary computational design platform that have demonstrated novel mechanisms of action for the treatment of multidrug-resistant infections. Using rational, statistical and algorithmic design principles, the technology amplifies antimicrobial activity while also achieving a strong safety profile, generating broad- and narrow-spectrum antibiotics that demonstrate a substantially lower risk of generating drug resistance than existing solutions.
