LAWRENCEVILLE, N.J., May 1, 2013 /PRNewswire/ --Celsion Corporation (NASDAQ:
CLSN) announced today that Professor Riccardo Lencioni, MD, FSIR, EBIR, 2013
WCIO Program Chairman and the Director of the Division of Diagnostic Imaging
and Intervention at Pisa University School of Medicine in Italy and Lead
European Principal Investigator for Celsion's Phase III HEAT Study and Ronnie
T.P. Poon, MD, MS, PhD, FRCS(Edin), FACS, Professor of Surgery at the
University of Hong Kong and Lead Asia Pacific Principal Investigator for
Celsion's Phase III HEAT Study will,in conjunction with their scientific
presentations, review the clinical trial results including new emerging
findings from the HEAT Study post hoc analysis at the 9^th Annual Meeting of
the World Conference on Interventional Oncology, which is being held May 16 –
20, 2013 in New York City. The Company recently reported, based on the post
hoc analysis, that ThermoDox® in combination with radiofrequency ablation
(RFA) markedly improved progression free survival (PFS) and overall survival
(OS) in patients who had optimal RFA. Dr. Lencioni's presentation, titled
"Advances in Image-Guided Ablation" will be held Thursday, May 16, 2013 at
11:00 a.m. EDT in Plenary Session: Multidisciplinary State-of-the Art: HCC and
Professor Poon's presentation, titled "Thermally Sensitive Drug Carriers" will
be held Thursday, May 16, 2013 at 4:30 p.m. EDT in Concurrent Session: New
Drugs/New Carriers/New Devices.

Celsion has conducted a comprehensive analysis of the data from the Phase III
HEAT Study of ThermoDox® in hepatocellular carcinoma (HCC) with key principal
investigators, data experts and liver cancer experts including Professors
Lencioni and Poon. This analysis followed the announcement on January 31,
2013, that ThermoDox® in combination with RFA did not meet the Study's primary
endpoint. Emerging data from the HEAT Study post hoc analysis demonstrates
that ThermoDox® markedly improves progression free survival (PFS) and overall
survival (OS) in patients if their lesions undergo RFA for 45 minutes or
more. These findings apply to HCC lesions from both size cohorts of the HEAT
Study (3-5 cm and 5-7 cm) and represent a sizable subgroup of patients.

"The HEAT Study is the largest clinical trial ever conducted in the field of
image-guided ablation of HCC; as such, there is a trove of important data
emerging from this study regarding the use of ThermoDox® in conjunction with
RFA to treat this serious, deadly cancer," said Professor Lencioni. "I am
pleased to introduce this analysis of a large subgroup which may be indicating
a meaningful clinical benefit in both PFS and overall survival at WCIO. The
details of the data will be presented for peer review at upcoming scientific
meetings. It is important to note that the duration of heat from the RFA
procedure appears to be a key factor in a successful clinical outcome when
combined with ThermoDox® as suggested by this analysis. These findings are
consistent with our understanding of how RFA plus ThermoDox® can potentially
offer an important new treatment for this underserved patient population."
