AMR innovation inspired by nature

We transformphage technologyto deliver the next generation of precision medicine.

Unmet Medical Need

By 2050, AMR could claim over 50 million lives every year unless we act now.

"Despite this critical need, it’s been >35 years since the last new class of antibiotics hit the market. The clock is ticking—it’s time to revitalize the pipeline with innovative, precision-targeted antimicrobial drugs.

A targeted approach to addressing antibiotic resistance

Amid growing global concerns over antibiotic resistance, PhalconBio is advancing the next generation of antibacterial precision medicines. These targeted therapies are designed to revolutionize patient care, offering a sustainable and innovative alternative to traditional antibiotics. PhalconBio's technology platform transforms conventional phage therapy by enhancing its efficacy, reducing the emergence of drug resistance, while maintaining drug specificity. The result: highly effective and safe new medicines that set a new standard in antibacterial treatment.

The Basis

Phage Therapy

Bacteriophages (or phages), are viral predators that specifically infect and kill bacteria, making them a powerful tool for treating bacterial infections. Unlike broad-spectrum antibiotics, phages target specific pathogenic bacterial species, minimizing harm to beneficial bacteria and reducing the risk of disrupting the microbiome. Phages are a safe and promising solution to combat drug-resistant infections. At PhalconBio, we improve and functionalize phage therapies through targeted engineering.

The usp

PhalconBio's Engineered Phage Therapeutics (EPTs)

PhalconBio’s EPTs are genetically enhanced bacteriophages that integrate precision targeting with phage-mediated delivery of antibacterial effector proteins. These engineered phages not only seek out and eliminate pathogenic bacteria but also reprogram them to produce secondary precision antimicrobials directly at the site of infection. This innovative, highly targeted approach mediates a two-pronged attack:

• Improve antibacterial efficacy
• Minimize resistance development
• Improve biofilm targeting

PhalconBio's proprietary EPT platform technology has been developed in close collaborations with our partners at ETH Zurich and builds on > 10 years of engineering research.

Our lead program: Targeting pulmonary Pseudomonas aeruginosa infections

Pseudomonas aeruginosa is a highly adaptable opportunistic pathogen known for causing severe disease, including pneumonia, bloodstream infections, and wound infections. Renowned for its intrinsic antibiotic resistance and ability to form biofilms, P. aeruginosa poses a significant challenge in clinical settings, making it a critical target in the fight against antimicrobial resistance. Our lead program focuses on pulmonary P. aeruginosa infections, which are typically associated with chronic structural lung diseases including bronchiectasis, cystic fibrosis, primary ciliary dyskinesia as well as acute hospital-acquired or ventilator-associated pneumonia.

Our platform technology is adaptable to other ESKAPEE pathogens.
