Company to Hold Conference Call on Wednesday, May 15, 2019 at 11:00 a.m. EDT
LAWRENCEVILLE, N.J, May 15, 2019 (GLOBE NEWSWIRE) -- Celsion Corporation (CLSN), an oncology drug development company, today announced financial results for the quarter ended March 31, 2019 and provided an update on its development programs for ThermoDox®, its proprietary heat-activated liposomal encapsulation of doxorubicin, and GEN-1, an IL-12 DNA plasmid vector encased in a nanoparticle delivery system, which enables cell transfection followed by persistent, local secretion of the IL-12 protein. The Company's lead program is ThermoDox®, which is currently in Phase III development for the treatment of hepatocellular carcinoma (HCC), or primary liver cancer. The Company's immunotherapy candidate, GEN-1, is currently in Phase I/II development for the localized treatment of newly diagnosed Stage III/IV ovarian cancer.
“Celsion continues to make significant progress with our two ongoing clinical development programs for ThermoDox® and GEN-1. With sound fundamentals and a strong balance sheet, we are well positioned to see our clinical programs through transformative milestones over the next year. We are looking forward to the first of two preplanned, interim efficacy analyses for the Phase III OPTIMA Study expected in the second half of 2019 and mid-2020, respectively. This global, pivotal study completed patient enrollment in August 2018 at over 65 clinical sites in 14 different countries, including all of the markets where primary liver cancer is a major problem,” said Michael H. Tardugno, Celsion's chairman, president and chief executive officer. “Our Phase I/II OVATION 2 Study in newly diagnosed ovarian cancer is now recruiting patients and continues to work through the activation of up to 31 clinical sites by the end of this year. Importantly, enrollment of patients in the Phase I portion of the study is expected to be complete and initial data reported by the end of 2019. This promising clinical development program in immunotherapy has generated impressive results in previous trials.”
Issuance of New U.S. Patent for ThermoDox®. On April 17, 2019, the Company announced that the United States Patent and Trademark Office granted U.S. Patent No. 10,251,901 B2 – Thermosensitive Nanoparticle Formulations and Method of Making the Same, which is directly applicable to the method of treating cancer using a new ThermoDox® formulation. The claim covers a method for preparing (as well as the composition of) a doxorubicin sulfate temperature-sensitive liposome and extends coverage time over ThermoDox’s current patent portfolio to 2033. This new patent broadens our intellectual property portfolio providing for life cycle management of ThermoDox® well into the future.
Publication of ThermoDox® Study Results in the Peer-Reviewed Journal, Radiology. On January 17, 2019, the Company announced that results from the Phase I TARDOX trial of ThermoDox® conducted at the University of Oxford, United Kingdom, were published in the peer-reviewed journal, Radiology. The findings published in Radiology serve as a companion paper to the groundbreaking work published in Lancet Oncology in July 2018. This was the first published study to evaluate ThermoDox® when combined with high-intensity focused ultrasound (HIFU). The Radiology publication was accompanied by an editorial highlighting the significance of utilizing HIFU to safely deliver oncologically relevant concentrations of doxorubicin with ThermoDox®.
The article, titled, “Focused Ultrasound Hyperthermia for Targeted Drug Release from Thermosensitive Liposomes: Results from a Phase I Trial,” included an evaluation of the TARDOX results and the safety, efficacy and utility of treatment with ThermoDox® plus targeted, non-invasive ultrasound in patients with solid liver tumors, with treatment plans based on patient-specific modeling.
The Phase I TARDOX study was carried out as a multi-disciplinary collaboration between Celsion, the Oxford University Institute of Biomedical Engineering, the Oncology Clinical Trials Office (OCTO) and the Oxford University Hospitals NHS Foundation Trust and evaluated patients with inoperable primary or secondary liver tumors who had previously received chemotherapy. In this trial, 10 patients received a single intravenous dose of 50 mg/m2 of ThermoDox®, and ultrasonic heating of target tumors was monitored in six participants using a minimally invasive temperature sensor, while four patients were treated without real-time thermometry. The study demonstrated that focused ultrasound exposure with ThermoDox® resulted in increased chemotherapy concentrations within liver tumors that were an average of 3.7 times greater than preheating levels across all 10 patients in the study.
Safety was assessed by analysis of magnetic resonance imaging (MRI) and biopsy specimens for evidence of thermal ablation, as well as adverse event monitoring. There was no evidence of focused ultrasound-related adverse effects, including thermal ablation.
Presentation of GEN-1 Clinical Development Program at ASCO-SITC Clinical Immuno-Oncology Symposium. On March 4, 2019, the Company announced the oral presentation of data highlighting the safety, clinical response and translational data from the OVATION I Study by Premal H. Thaker, M.D., M.S., a nationally recognized expert in gynecologic oncology, Associate Professor of Obstetrics and Gynecology at the Siteman Cancer Center at the Washington University School of Medicine in St. Louis at the ASCO-SITC Clinical Immuno-Oncology Symposium.
Dr. Thaker’s presentation highlighted the following:
- The Phase IB OVATION I Study, which evaluated escalating doses of GEN-1 (36 mg/m2, 47 mg/m2, 61 mg/m2 and 79 mg/m2) administered intraperitoneally in combination with three cycles of neoadjuvant chemotherapy (NAC) prior to interval debulking surgery, followed by three cycles of NAC in the treatment of newly diagnosed patients with Stage III/IV ovarian cancer, demonstrated median PFS of 21 months in patients treated per protocol (n=14) and 17.1 months for the intent-to-treat population (n=18) for all dose cohorts, including three patients who dropped out of the study after 13 days or less, each of which compared favorably to the PFS historical average of 12 months for women with Stage III/IV ovarian cancer.
- Of the 14 patients who were evaluable for response, 100% of patients administered NAC plus the two higher doses of GEN-1 experienced an objective tumor response (defined as a partial or complete response) compared to only 60% of patients given the two lower doses.
- Patients in the two higher dose cohorts also had a high surgery success rate, with 88% of these patients achieving the optimal outcome of a complete (R0) resection. 100% of patients treated at the highest dose cohort had a complete R0 resection.
- Pre- and post-treatment levels of key ovarian cancer biomarkers were also measured as part of this study and showed marked reduction in immunosuppressive response across multiple biomarkers post-treatment, including FOXP3 and IDO-1 – an outcome not previously observed with NAC treatment alone.
