Celsion Corporation Reports Second Quarter 2012 Financial Results and Business Update

Company to Hold Conference Call on Tuesday, August 14, 2012 at 11:00 a.m. ET

LAWRENCEVILLE, N.J. - August 14, 2012 - Celsion Corporation (NASDAQ: CLSN), a leading oncology drug development company, today announced financial results for the second quarter ended June 30, 2012 and provided a business update including development progress with ThermoDox , Celsion's proprietary heat-activated liposomal encapsulation of doxorubicin for the treatment of hepatocellular carcinoma (HCC), commonly referred to as primary liver cancer. ThermoDox is currently being evaluated under a Special Protocol Assessment with the U.S. Food and Drug Administration (FDA) in a global, multi-center, randomized, pivotal Phase III trial (the HEAT Study) in patients with non-resectable primary liver cancer. The HEAT Study has been designated as a Priority Trial for liver cancer by the National Institutes of Health, has received Fast Track Designation from the FDA and has received Orphan Drug Designation in both the U.S. and Europe. ThermoDox is also being evaluated in two Phase II trials for patients with recurrent chest wall breast cancer and colorectal liver metastases.

"Celsion has had a productive, if not pivotal, quarter in its development program for ThermoDox , an investigational drug with the potential to provide a first line therapy for patients with HCC, the largest unmet need in oncology. Having successfully completed patient enrollment in the HEAT Study, secured a commercial supply agreement for ThermoDox in China, entered into a $10 million loan agreement which strengthens our balance sheet well beyond data, and advanced several important collaborations with leading industry and academic players, we are well positioned for success," said Michael H. Tardugno, Celsion's President and Chief Executive Officer. "Our continued progress underscores the momentum and enthusiasm behind our ThermoDox program, and its advancement toward the key clinical, regulatory and commercial milestones ahead. Among the most important of these near-term milestones, we look forward to top line results from the pivotal HEAT Study."

A total of 380 events of progression are required to reach the planned final analysis of the HEAT Study, which are projected to occur in late 2012. Top line results will be announced following review by the study's independent Data Monitoring Committee.

Mr. Tardugno added, "Beyond the HEAT Study, we are very encouraged by the progress being made with ThermoDox in multiple indications using a variety of heat-based modalities in collaboration with some of the top names in science and healthcare, including Royal Philips Electronics, Oxford University and the University of Washington. These collaborations, along with our own clinical programs, we believe will bear out ThermoDox 's significant clinical potential as it progresses through the commercialization process."

In the first six months of 2012, Celsion recorded a $370,000 non-cash charge related to the change in the common stock warrant liability compared to a non-cash charge of $418,000 in the same period last year.

Research and development costs decreased by approximately $0.9 million to $4.1 million in the second quarter of 2012 compared to $5.0 million in the same period of 2011. Research and development costs decreased by approximately $0.5 million to $8.8 million in the first six months of 2012 compared to $9.3 million in the same period of 2011. The decreased costs in each of these periods were primarily due to lower investigator grants and related monitoring activities associated with the HEAT Study partially offset by increased activities related to the development of commercial manufacturing capabilities for ThermoDox , including the production of registration batches. General and administrative expenses increased by approximately $0.3 million to $1.6 million in the second quarter of 2012, from $1.3 million for the same period in 2011. General and administrative expenses increased by approximately $0.7 million to $3.2 million in the first six months of 2012, from $2.5 million for the same period in 2011. This increase in each of these periods is largely the result of an increase in professional fees and personnel costs to support the Company's growth.

About ThermoDox and the Phase III HEAT Study

ThermoDox is a proprietary heat-activated liposomal encapsulation of doxorubicin, an approved and frequently used oncology drug for the treatment of a wide range of cancers. In the HEAT Study, ThermoDox is administered intravenously in combination with Radio Frequency Ablation (RFA). Localized mild hyperthermia (39.5 - 42 degrees Celsius) created by the RFA releases the entrapped doxorubicin from the liposome. This delivery technology enables high concentrations of doxorubicin to be deposited preferentially in a targeted tumor.

For primary liver cancer, ThermoDox is being evaluated in a global, multi-center, randomized, pivotal Phase III HEAT Study at 79 clinical sites under an FDA Special Protocol Assessment. The study is designed to evaluate the efficacy of ThermoDox in combination with RFA when compared to patients who receive RFA alone as the control. The primary endpoint for the study is progression-free survival with a secondary confirmatory endpoint of overall survival. Additional information on the Company's ThermoDox clinical studies may be found at www.clinicaltrials.gov.
