Translational research data was reviewed with leading immuno-oncology experts from the Roswell Park Cancer Institute. The analysis of peritoneal fluid and blood samples collected immediately before and 24 hours after IP administration of multiple doses of GEN-1 (36, 47, 61, 72 mg/m2) and standard NACT (carboplatin every 21 days and Taxol weekly) shows clear evidence of IL-12 gene transfer by dose dependent increases in IL-12 levels and immune system activity and significant increases in interferon-gamma (IFN- γ) and decreases in VEGF levels. The treatment-related changes in immune activating cytokines and pro-tumor VEGF levels followed a dose-dependent trend and were predominantly in the peritoneal fluid compartment with little to no changes observed in the patients’ systemic blood stream.
Key translational research findings from the first 12 of 15 patients¹ enrolled in four patient cohorts are summarized below:
“These translational research findings demonstrate that GEN-1 in ovarian cancer patients is biologically active and creates a shift in the tumor microenvironment in the peritoneal cavity in a dose-dependent manner and promotes a pro-immune T-cell population dynamic in the tumor microenvironment,” said Dr. Khursheed Anwer, Celsion’s executive vice president and chief science officer. “These distinct immunological changes in the local disease environment appear to translate into clinical benefit and warrant the continued development of our GEN-1 IL-12 immunotherapy as a potential adjuvant, in both first and second-line ovarian cancer. Furthermore, pro-immune changes in the tumor microenvironment appear to support research combining GEN-1 with other exciting immuno-oncology therapies including adaptive T-cell and check point inhibitors.”
The Company previously announced the latest clinical findings from the OVATION Study in a poster presentation at the American Society of Clinical Oncology (ASCO) 2017 Annual Meeting in June 2017. The presentation summarized clinical findings for all fourteen patients treated in the trial to-date.
“The impressive early trends in tumor response, surgical resections and progression-free survival are consistent with the dose dependent increases in IFN- γ levels, decreases in VEGF levels and immune system activity observed in the translational data,” said Michael H. Tardugno, Celsion's chairman, president and chief executive officer. “Ovarian cancer patients have a very poor prognosis. These data along with other published, pre-clinical data, underscore the potential of GEN-1 to serve as an effective, safe IL-12 immunotherapy in this underserved population.”
About Celsion Corporation
Celsion is a fully-integrated oncology company focused on developing a portfolio of innovative cancer treatments, including directed chemotherapies, immunotherapies and RNA- or DNA-based therapies. The Company's lead program is ThermoDox®, a proprietary heat-activated liposomal encapsulation of doxorubicin, currently in Phase III development for the treatment of primary liver cancer and in Phase II development for the treatment of recurrent chest wall breast cancer. The pipeline also includes GEN-1, a gene-mediated immunotherapy for the localized treatment of ovarian and brain cancers. Celsion has two platform technologies for the development of novel nucleic acid-based immunotherapies and other anticancer DNA or RNA therapies, including TheraPlas™ and TheraSilence™.
