LAWRENCEVILLE, N.J., Aug. 15, 2017 (GLOBE NEWSWIRE) -- Celsion Corporation (NASDAQ:CLSN), an oncology drug development company, today announced financial results for the quarter and six month period ended June 30, 2017 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 primary liver cancer. The Company's immunotherapy program consists of GEN-1 and is currently in Phase I development for the localized treatment of ovarian cancer.
"We are extremely pleased with the momentum that we have built and the meaningful developments in our two lead programs," said Michael H. Tardugno, Celsion's chairman, president and CEO. "The data from our immunotherapy program, both the clinical data as well as the recently announced translational data from our OVATION Study in first line ovarian cancer, continue to provide important insights into GEN-1's favorable clinical and safety profile and reinforce our confidence in its potential to serve as an effective therapy in a broad range of cancers."
Mr. Tardugno continued, "We have also made great strides to advance our global Phase III OPTIMA Study evaluating ThermoDox® in primary liver cancer, with clinical sites currently enrolling patients in 14 countries worldwide. In addition, we are pleased to report that the independent Data Monitoring Committee recently recommended continuation of the OPTIMA Study after their review of the safety and efficacy data for 275 patients enrolled in the study. Enrollment momentum continues to improve with the addition of new clinical sites in China and Vietnam."
OPTIMA Study Update. On August 7, 2017, the Company announced that the independent Data Monitoring Committee (DMC) for the Company's OPTIMA Study completed a regularly scheduled review of the first 50% of patients enrolled in the trial as of April 2017 and has unanimously recommended that the OPTIMA Study continue according to protocol to its final data readout. The DMC reviewed study data at regular intervals, with the primary responsibilities of ensuring the safety of all patients enrolled in the study, the quality of the data collected, and the continued scientific validity of the study design. As part of its review, the DMC monitored a quality matrix relating to the total clinical data set, confirming the timely collection of data, that all data are current as well as other data collection and quality criteria.
The Company hosted an Investigators Meeting with physicians in SE Asia and key opinion leaders on July 22-23, 2017 in Bangkok, Thailand. A second Investigators Meeting is being planned for October with physicians in China. The Company has initiated approximately 70 clinical sites in 14 countries with plans to activate up to 8 additional clinical trial sites in China or Vietnam by the end of 2017. China and Vietnam represent significant markets for ThermoDox® where HCC incidence rates are among the highest in the world.
In addition, the Company announced that patient enrollment in the 550 patient Phase III global study has reached over 60%. Based on current enrollment rates, the Company expects to complete enrollment of the OPTIMA Study by mid - 2018.
Announced Latest Translational Data from the OVATION Study Showing That Patients in All Cohorts Showed Convincing Evidence of IL-12 Gene Transfer and Immune System Activity. On August 2, 2017, the Company reported that translational research data from its Phase Ib dose escalating clinical trial was reviewed with leading immuno-oncology experts from the Roswell Park Cancer Institute. The data showed 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 patients enrolled in four patient cohorts are summarized below:
- The treatment-related changes in immune activating cytokines and pro-tumor VEGF and IFN- γ levels followed a dose-dependent trend and were predominantly in the peritoneal fluid compartment with little to no changes observed in the patients’ systemic circulation. The observed immunological changes are consistent with an IL-12 based mechanism.
- Effects observed in the immunohistochemistry (IHC) analysis were pronounced decreases in the density of immunosuppressive T-cell signals (FoxP3, PD-1, PDL-1, IDO-1) and increases in CD8+ cells in the tumor microenvironment.
- The ratio of CD8+ cells to immunosuppressive cells was increased in approximately 75% of patients suggesting an overall shift in the tumor microenvironment from immunosuppressive to pro-immune stimulatory following treatment with GEN-1. An increase in CD8+ to immunosuppressive T-cell populations is a leading indicator and believed to be a good predictor of improved overall survival.
Presented OVATION Study Findings in Newly Diagnosed Advanced Ovarian Cancer Patients at the ASCO 2017 Annual Meeting. In June 2017, the Company reported clinical data from the first fourteen patients who have completed treatment in the OVATION Study. GEN-1 plus standard chemotherapy produced positive results, with no dose limiting toxicities and promising dose dependent efficacy signals which appear to correlate well with successful surgical outcomes as summarized below:
- Of the fourteen patients treated to date in the entire study, two (2) patients demonstrated a complete response, ten (10) patients demonstrated a partial response and two (2) patients demonstrated stable disease, as measured by RECIST criteria. This translates to a 100% disease control rate ("DCR") and an 86% objective response rate ("ORR"). Of the five patients treated in the highest dose cohort, there was a 100% objective response rate with one (1) complete response and four (4) partial responses.
- Fourteen patients had successful resections of their tumors, with nine (9) patients (64%) having an R0 resection, which indicates a microscopically margin-negative resection in which no gross or microscopic tumor remains in the tumor bed. Of the five patients treated at the highest dose cohort, all five patients (100%) experienced a R0 surgical resection. Seven out of eight (87%) patients in the highest two dose cohorts experienced a R0 surgical resection.
- All patients experienced a clinically significant decrease in their CA-125 protein levels as of their most recent study visit. CA-125 is used to monitor certain cancers during and after treatment. CA-125 is present in greater concentrations in ovarian cancer cells than in other cells.
- Of the seven patients who have received GEN-1 treatment over one year ago and are being followed, only one patient’s cancer has progressed after 11.7 months. This compares favorably to the historical median progression free survival (PFS) of 12 months for newly-diagnosed patients with Stage III and IV ovarian cancer that undergo neoadjuvant chemotherapy followed by interval debulking surgery. Of the remaining six patients who have been on the study for over one year, their average PFS is 16.4 months with the longest progression-free patient at over 22 months.
Raised $10.1 Million through Warrant Exercises and Registered Direct Offering. During the second quarter of 2017, the Company raised $5.1 million through the exercise of outstanding common stock warrants. In July 2017, the Company completed a $5 million registered direct equity offering of shares of common stock, or pre-funded warrants in lieu thereof, and a concurrent private placement of warrants to purchase common stock with several institutional healthcare investors.
For the quarter ended June 30, 2017, Celsion reported a net loss of $4.9 million, or $(0.79) per share, compared to a net loss of $4.5 million, or $(2.63) per share, in the same period of 2016. Operating expenses were $4.7 million in the second quarter of 2017 compared to $4.9 million in the same period of 2016. This decrease was primarily due to a tighter clinical development focus coupled with lower general and administrative and interest expenses. For the six month period ended June 30, 2017, the Company reported a net loss of $10.1 million, or $(1.75) per share, compared to $10.2 million, or $(6.04) per share, in the same six month period of 2016. Operating expenses were $9.6 million in the first half of 2017 compared to $10.2 million in the same period of 2016. Net cash used in operations was $7.3 million in the first half of 2017 compared to $9.0 million in the same period last year. The Company ended the second quarter of 2017 with $3.6 million of total cash and investments, which was subsequently increased with proceeds from a $5 million registered direct offering completed in early July 2017.
Research and development costs were $3.0 million in the second quarter of 2017 compared to $3.3 million in the same period last year. Research and development costs were $6.5 million in the first half of 2017 compared to $6.8 million in the same period last year. Clinical development costs for the Phase III OPTIMA Study remained relatively unchanged at $1.5 million in each of the second quarter of 2017 and 2016. R&D costs for other development programs were lower as a result of the Company’s tighter clinical development focus around the pivotal Phase III OPTIMA Study for the treatment of primary liver cancer and the clinical development program for GEN-1 IL-12 immunotherapy for the localized treatment of ovarian cancer coupled with lower costs in the first half of 2017 associated with the production of ThermoDox® clinical supplies to support the OPTIMA Study.
General and administrative expenses were $1.6 million in the second quarter of 2017 compared to $1.5 million in the same period of 2016. The increase during the second quarter of 2017 was due to higher non-cash stock compensation expense partially offset by reduced professional fees. General and administrative expenses were $3.1 million in the first half of 2017 compared to $3.4 million in the same period of 2016. The decrease during the first six months of 2017 was primarily the result of lower personnel costs and professional fees.
During the three and six months ended June 30, 2017, the Company recognized deemed dividends totaling $0.4 million collectively in regard to multiple agreements with certain warrant holders, pursuant to which these warrant holders agreed to exercise, and the Company agreed to reprice, certain warrants. Warrants to purchase 790,410 shares of common stock were repriced at $2.70 and warrants to purchase 506,627 shares of common stock were repriced at $1.65. The Company received $3.0 million in gross proceeds from the sale of these repriced warrants.
