Press Release Details

LAWRENCEVILLE, N.J., Aug. 10, 2015 /PRNewswire/ -- Celsion Corporation (NASDAQ: CLSN), an oncology drug development company, today announced financial results for the quarter ended June 30, 2015 and provided an update on its development programs, including ThermoDox®, its proprietary heat-activated liposomal encapsulation of doxorubicin, and GEN-1, an IL-12 DNA-based immunotherapy encased in a synthetic nanoparticle delivery system, which is currently under development for the localized treatment of ovarian and brain cancers. 

"Over the past few months, we reported positive data highlighting the multiple development opportunities for our portfolio, launched our European Early Access Program for ThermoDox in recurrent chest wall breast cancer and strengthened our balance sheet, providing a strong foundation as we advance our pipeline," said Michael H. Tardugno, Celsion's chairman, president and CEO.  "We remain on track to initiate key clinical studies this year, including the Euro-DIGNITY study evaluating ThermoDox in breast cancer, a Phase 1b trial for GEN-1 in first-line ovarian cancer, and a trial evaluating GEN-1 with Avastin® in platinum-resistant ovarian cancer patients. In parallel, we continue enroll patients from North America, Europe and Asia Pacific in our global Phase III OPTIMA Study evaluating ThermoDox® in primary liver cancer.  Finally, we continue to evaluate ways to leverage our TheraSilence technology platform to advance the development of RNAi therapeutics that can be delivered directly to the lung."

Recent Developments

ThermoDox®

Reported Positive Interim Data from the Phase II US DIGNITY Study in RCW Breast Cancer. 

In July 2015, Celsion announced continuing positive interim data from its Phase II DIGNITY trial of ThermoDox® in recurrent chest wall (RCW) breast cancer.  Of the 17 patients enrolled and treated in the DIGNITY Study, 13 were eligible for evaluation of efficacy.  Based on available data, every patient experienced a clinical benefit of their highly refractory disease with a local response rate of 69% observed in the 13 evaluable patients, notably 5 complete responses, 4 partial responses and 4 patients with stable disease.

Announced Updated Overall Survival Data from Phase III HEAT Study, Providing Strong Support for the Clinical Protocol for the Phase III OPTIMA Study. 

As of July 15, 2015, the latest Overall Survival (OS) analysis demonstrated that in a large, well bounded, subgroup of patients (n=285, 41% of the study patients), the combination of ThermoDox® and optimized RFA provided a 58% improvement in OS compared to optimized RFA alone. The Hazard Ratio at this analysis is 0.63 (95% CI 0.43 - 0.93) with a p-value of 0.0198. Median overall survival for the ThermoDox® group has been reached which translates into a 25.4 month (2.1 year) survival benefit over the optimized RFA only group (79 months for the ThermoDox® plus optimized RFA group versus 53.6 months for the optimized RFA only group).  These data continue to support the protocol for the Phase III OPTIMA Study, which is evaluating ThermoDox® in combination with optimized RFA, which will be standardized to a minimum of 45 minutes across all investigators and clinical sites for treating lesions 3 to 7 centimeters, versus standardized RFA alone. The study is expected to enroll up to 550 patients globally in up to 75 clinical sites in the United States, Europe, China and Asia Pacific.

Launched the ThermoDox® Early Access Program (EAP) in Europe.

The Company and myTomorrows launched the ThermoDox Early Access Program in the second quarter, making ThermoDox® available for sales to physicians who are treating patients with limited therapeutic options. The EAP provides physicians with access to products in later stage development demonstrating evidence of clinical benefit, with an acceptable safety profile and a quality manufacturing process in place.  Celsion will be allowed to price ThermoDox at commercial rates.

GEN-1 IL-12 DNA-Based Immunotherapy

Presented Phase Ib Data for GEN-1 in Platinum-Resistant Ovarian Cancer at ASCO.   

In May 2015, Celsion presented clinical results from the Phase Ib trial for GEN-1in combination with pegylated doxorubicin in 16 patients with platinum-resistant ovarian cancer in a poster session at the 2015 American Society of Clinical Oncology (ASCO) Meeting in Chicago.  The clinical findings demonstrated an overall clinical benefit of 57% for all treatment arms, with a partial response (PR) rate of 21% and a stable disease (SD) rate of 36%. The overall clinical benefit observed at the highest dose cohort in this difficult-to-treat patient population was 100% (PR=33% and SD=67%) in all six evaluable patients. GEN-1 was well tolerated, with no dose limiting toxicities and no overlapping toxicities between GEN-1 and pegylated doxorubicin. 

TheraSilence™

Demonstrated Potent, Durable Preclinical Lung Expression Data for Its TheraSilence™.

In May 2015, Celsion reported data from a preclinical study confirming that its TheraSilence™ technology platform can safely and effectively deliver RNA to the lungs in non-human primates, enabling the development of RNA therapeutics for lung diseases. In the study, TheraSilence-formulated signaling RNA resulted in preferential expression in the lungs, with expression in the liver at less than 15% of expression levels observed in the lungs, and expression levels in tissues other than the lung, spleen and liver at very low or background levels. A liver-directed delivery system, used as a positive control for the study, yielded preferential expression in liver and spleen, with only background expression levels observed in the lung.

Published Preclinical Data Demonstrating Lung Specific Delivery of microRNA-145 Inhibitor Using the TheraSilence™ Platform.

In May 2015, an abstract published in the Journal of Controlled Release summarized findings from a preclinical study confirming effective delivery of RNA to lung cells.   In the study, the Company's TheraSilence™ technology platform safely and effectively delivered an inhibitor of microRNA-145 (miR-145) in a well-established model of severe occlusive pulmonary arterial hypertension (PAH).  Treatment was associated with significant delivery of miR-145 inhibitor in the lung, inhibition of miR-145 levels and reversal of the pulmonary hypertension associated with the advanced stages of the disease leading to a normalization of cardiovascular function. 

Corporate Developments

Raised $8 Million Through Registered Direct Equity Offering priced "at the market".

During the second quarter of 2015, the Company completed an $8 million at-the-market registered direct equity offering and a concurrent private placement of warrants to purchase common stock with two institutional healthcare investors.

Financial Results

For the quarter ended June 30, 2015, Celsion reported a net loss of $5.7 million, or $(0.27) per share, compared to a net loss of $6.7 million, or $(0.38) per share, in the same period of 2014. Operating expenses were $5.4 million in the second quarter of 2015 compared to $6.5 million in the same period of 2014.  For the six month period ended June 30, 2015, the Company reported a net loss of $12.7 million, or $(0.62) per share, compared to $12.1 million, or $(0.71) per share, in the same period of 2014.  Operating expenses were $11.9 million in the first half of 2015 compared to $11.9 million in the same period of 2014.  Net loss and operating expenses for the three-month and six-month periods ended June 30, 2014 included $1.1 million of one-time costs associated with the acquisition of EGEN, Inc.   Net cash used in operations was $11.6 million in the first half of 2015 compared to $9.0 million in the same period last year.  The Company ended the second quarter of 2015 with $30.8 million of total cash, investments and accrued interest on these investments, which included the proceeds of an $8 million registered direct offering that was completed during the quarter.
