CHICAGO: Scientists at the ADA Forsyth Institute have identified a promising new narrow-spectrum antibiotic, FP-100, capable of eradicating Fusobacterium nucleatum, a key pathogen responsible for periodontitis, while preserving beneficial bacteria in the oral and gut microbiomes.
This groundbreaking discovery marks a major shift in antibiotic development, addressing the growing concern over antibiotic-resistant superbugs and the limitations of current periodontal disease treatments. The findings were published in the Journal of Oral Microbiology and funded by Flightpath Biosciences Inc.
FP-100: A Paradigm Shift in Treating Periodontitis
Dr. Alpdogan Kantarci, D.D.S., Ph.D., senior scientist at ADA Forsyth and the study’s lead researcher, emphasized the significance of FP-100’s targeted action:
“Often, antibiotics treating that disease will also kill all the bacteria that aid in preventing overpopulation of pathogens. With the increase of antibiotic-resistant superbugs, being able to kill a dangerous pathogen with a narrow-spectrum antimicrobial drug candidate represents a significant paradigm shift in antibiotic development.”
The study demonstrated FP-100’s effectiveness in in vitro experiments and mouse models, where it successfully eradicated Fusobacterium nucleatum, reversed tissue destruction, and prevented disease progression—without disrupting the healthy oral microbiome.
Beyond Oral Health: Systemic Implications of FP-100
The implications of this discovery extend beyond gum disease. Fusobacterium nucleatum has been linked to severe systemic health conditions, including:
- Colorectal cancer
- Preterm birth
- Alzheimer’s disease
Dr. Kantarci explained how Fusobacterium nucleatum behaves like a Trojan horse, traveling from the oral cavity to other parts of the body, where it colonizes and contributes to disease:
“Studies show it can travel from the oral cavity to other places, where it colonizes and causes disease. Eliminating the bacteria early in the oral cavity is also systemic prevention.”
FP-100 was originally rediscovered during research on Borrelia burgdorferi, the bacterium that causes Lyme disease.
Next Steps: Clinical Trials Underway
ADA Forsyth and Flightpath Biosciences have filed a joint patent application for FP-100 and are currently conducting phase I clinical trials to assess the antibiotic’s safety and tolerability in human participants. Further research aims to expand its application to other conditions caused by Fusobacterium nucleatum.
This discovery offers hope for millions suffering from periodontal disease and other serious health conditions, marking a critical advancement in targeted antibiotic therapy.
