Provectus announces acceptance of PV-10 abstract for presentation

Provectus Biopharmaceuticals announced that data from preclinical research on PV-10 for the treatments of human papillomavirus-positive and HPV-negative head and neck squamous cell carcinoma will be presented at the upcoming annual meeting of the American Association for Cancer Research, to be held April 5-10, 2024 in San Diego, California. The abstract, which was accepted for a poster presentation, is titled “PV 10 induces endoplasmic reticulum stress and autophagy, triggering immunogenic cell death and anti-tumor immunity in head and neck squamous cell carcinoma”. The work underlying this poster presentation is part of research conducted by Christine Chung, M.D., Chair, Department of Head and Neck-Endocrine Oncology and Program Leader of Head and Neck Oncology and members of the Chung laboratory at Moffitt Cancer Center in Tampa, Florida. According to Moffitt’s abstract, “…in vitro findings reveal that PV-10 induces cytotoxicity in both mEER and MTE-RAS cells. Notably, PV-10 promotes a significant increase in (reactive oxygen species), leading to an elevation in late apoptotic cells. Markers of immunogenic cell death , including a statistically significant increase in the release of damage-associated molecular pattern molecules HMGB1 and ATP, as well as enhanced surface expression of calreticulin, HSP-70, and HSP-90, were observed. At the molecular level, a remarkable activation of endoplasmic reticulum stress, pro-apoptotic protein, and autophagy markers were observed. Intratumoral PV-10 injection in vivo has shown significant tumor regression in both mEER and MTE-RAS tumors, and a complete response was noticed in some mice, indicating that PV-10 induces potent ICD in both mEER and MTE-RAS tumors.”
