The data from the IMMUNOCERV Phase 2 clinical trial were featured in an oral presentation by Aaron Seo, MD, PhD, of The University of Texas MD Anderson Cancer Center, at the American Society for Radiation Oncology (ASTRO 2023) Annual Meeting in San Diego, CA. The IMMUNOCERV Phase 2 trial is investigating PDS0101 in combination with SOC CRT in the treatment of cervical cancer patients with large tumors over 5 cm in size and/or cancer that has spread to the lymph nodes. HPV is the primary cause of cervical cancer with over 99% caused by HPV infection, and cfHPV-DNA can be detected in the blood of patients with cervical cancer. HPV type 16 (HPV16) is the most prominent subtype associated with cervical cancer. The study presented at ASTRO 2023 evaluated the relationship between the levels of circulating cfHPV-DNA and the extent of disease, clinical staging, and treatment response in patients with HPV-positive cervical cancer. “We are encouraged by this data from the IMMUNOCERV trial, which highlight the potential of PDS0101 to positively impact cfDNA, an emerging biomarker of clinical response in cervical and other HPV-related cancers,” said Lauren V. Wood, MD, Chief Medical Officer of PDS Biotech. “The findings complement previously presented IMMUNOCERV data which suggested PDS0101 promotes the induction of multifunctional ...
