Celsion Reports Second Quarter 2009 Financial Results and Business Update

Patient Enrollment Accelerates in ThermoDox(R) Global Phase III Primary Liver Cancer Study
25% of Patient Enrollment Target Achieved

COLUMBIA, Md., Aug 05, 2009 (BUSINESS WIRE) -- Celsion Corporation (NASDAQ:CLSN), a leading oncology drug development company, today announced financial results for the second quarter ended June 30, 2009.

"In the second quarter of 2009 we made excellent progress towards the completion of enrollment in the ThermoDox(R) global Phase III clinical trial for primary liver cancer," commented Michael H. Tardugno, Celsion's President and Chief Executive Officer. "The rate of enrollment is consistent with our projections. We now have enrolled 151 patients, or 25% of that required to complete the study. We were pleased to recently have announced the expansion of the study to Japan under the direction of our exclusive Japanese license partner, Yakult. This will accelerate our time to approval in Japan while also providing non-diluting financing from Yakult which is in addition to an $18 million milestone payment upon Japanese approval. Under our agreement, Yakult funds the cost of patients enrolled in Japan. Our pending China CTA remains under evaluation. We continue to be optimistic that we will receive approval for our trial in the near term. In addition, we are expanding the clinical study to the Philippines, Malaysia and Thailand and expect to have 55-60 clinical sites enrolling patients by year end. Assuming additional time is required to enroll the added minimum Japanese patient cohort, enrollment could be completed in the second quarter of 2010."

"Also in the second quarter of 2009, we enrolled our first patients in the Phase I/II recurrent chest wall (RCW) breast cancer clinical trial and we announced that ThermoDox(R) was the subject of three presentations at the Society for Thermal Medicine Annual Meeting, further increasing the drug's exposure within the physician and scientific communities."

About ThermoDox(R)

ThermoDox(R) in combination with hyperthermia has the potential to provide local tumor control and improve quality of life. ThermoDox(R) 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 including breast cancer. Localized mild hyperthermia (39.5-42 degrees Celsius) 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(R) is being evaluated in a 600 patient global Phase III study under an FDA Special Protocol Assessment. The study is designed to evaluate the efficacy of ThermoDox(R) 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. For recurrent chest wall breast cancer, ThermoDox(R) is being evaluated in a pivotal Phase I/II open-label, dose-escalating trial that is designed to measure durable local complete response at the tumor site. Celsion expects to enroll approximately 100 patients across the United States. Additional information on these ThermoDox(R) clinical studies may be found at http://www.clinicaltrials.gov
