Researchers at the University of Pennsylvania's School of Dental Medicine, led by Henry Daniell, have created a bioengineered chewing gum designed to fight human papillomavirus (HPV) and bacteria linked to head and neck cancer. In tests with oral samples from patients with head and neck squamous cell carcinoma, the gum reduced HPV by 93% in saliva and 80% in oral rinse samples, while nearly eliminating two harmful bacterial species while preserving beneficial oral bacteria. The team aims to advance the therapy to clinical trials as an adjuvant treatment or preventive measure.
- Bioengineered chewing gum made from lablab beans containing FRIL (antiviral protein) and engineered protegrin (antimicrobial peptide) reduced HPV by 93% in saliva samples and 80% in oral rinse samples from head and neck cancer patients.
- The treatment nearly eliminated Porphyromonas gingivalis and Fusobacterium nucleatum bacteria while preserving beneficial oral bacteria, unlike radiation therapy which damages healthy microbiota.
- Research team led by Henry Daniell at UPenn School of Dental Medicine published findings in Scientific Reports and plans to advance the therapy to clinical trials as an adjuvant or preventive treatment.
- Head and neck cancer ranks as the seventh leading cancer type worldwide; the gum may offer a more accessible and affordable treatment option alongside existing therapies.

Analysis Clinical development pathway
Daniell emphasizes that lip and oral cavity cancer ranked as the seventh leading cancer type in incidence and mortality worldwide in 2022, supporting the need to advance the therapy to clinical trials as adjuvants with current treatments or as prophylaxis.
“Our findings support the value of advancing these therapies to clinical trials as adjuvants with current treatments or as prophylaxis to prevent infection and transmission.”

“The global increase in oropharyngeal cancer is linked to HPV infection. And Pg and Fn infections worsen survival rates of untreated recurrent or metastatic oral cancer, even after surgery and risk-adjusted adjuvant, or supplemental, therapies.”
