LAWRENCEVILLE, N.J., Jan. 21, 2014 /PRNewswire/ -- Celsion Corporation
(NASDAQ: CLSN), a leading oncology drug development company, announced today
that the company is formalizing a program to pursue the development of
ThermoDox® to investigate applications for treating brain cancer tumors,
notably Glioblastoma Multiforme or GBM.In addition to jointly submitting
multiple grant applications, the company is also pursuing preclinical studies
in collaboration with Dr. Costas D. Arvanitis at the Brigham and Women's
Hospital and Harvard Medical School. Experiments will study the use of
ThermoDox in combination with MR guided High Intensity Focused Ultrasound
(HIFU) to treat brain tumors, initially in animal models.

"Brain cancer tumors represent a very high unmet medical need, and researchers
have been pursuing applications with HIFU for many years," said Nicholas
Borys, MD, Celsion's Chief Medical Officer. "We are excited to investigate
the addition of ThermoDox, our heat-activated liposomal encapsulation of
doxorubicin, which could provide some clinical benefit for a population that
desperately needs more applications."

Dr. Arvanitis, research fellow at Brigham and Women's Hospital and Harvard
Medical School stated, "We have investigated the use of MR-guided focused
ultrasound to treat brain tumors for many years and have identified the need
for drugs that will improve our ability to treat brain tumors. We are excited
about this drug design, which is positioned to work with heat and specifically
HIFU, and its potential to cross the blood-brain barrier and potentially
demonstrate drug concentration in ways that other drugs cannot. We are
grateful for Celsion's support in this research and look forward to pursuing
this initial, pre-clinical research with the hope of bringing this application
to the clinic in the future."

About Glioblastoma Multiforme (GBM) Brain Tumors

Glioblastoma multiforme (GBM), WHO classification name "glioblastoma", is the
most common and most aggressive malignant primary brain tumor in humans,
involving glial cells and accounting for over 50% of all functional tissue
brain tumor cases and nearly 20% of all intracranial tumors. In 2013,
projected US incidence of brain tumors approaches 23,000 cases, with projected
mortality at 14,000. Treatment can involve chemotherapy, radiation and
surgery. Median survival with standard-of-care radiation and chemotherapy is
normally 15 months, and Median survival without treatment is approximately 4½

About ThermoDox®

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 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 701 patient
global Phase III 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. On January 31, 2013, Celsion announced that ThermoDox® in combination
with RFA did not meet the primary endpoint of the HEAT study in patients with
hepatocellular carcinoma, also known as primary liver cancer. Celsion has
conducted a comprehensive analysis of the data from the Phase III HEAT Study
with key principal investigators, data experts and liver cancer experts.
Emerging data from the HEAT Study post hoc analysis demonstrates that
ThermoDox® markedly improves PFS and overall survival 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 approximately 300 patients.
