Celsion Corporation Announces Issuance Of Two New U.S. Patents For Its GEN-1 Immuno-Oncology Product

LAWRENCEVILLE, N.J., Nov. 04, 2016 (GLOBE NEWSWIRE) -- Celsion Corporation (NASDAQ:CLSN), a clinical stage oncology drug development company, today announced that the United States Patent and Trademark Office (USPTO) has granted two patents: Patent No. 9,468,687 B2 - Immuno Gene Therapy for Treatment of Cancer and Hyperproliferative Diseases, which expands the use of GEN-1 into additional cancer treatment modalities in combination with other chemotherapeutics and Patent No. 9,144,546 - Nucleic Acid-Lipopolymer Compositions, which expands and extends previous patent claims on the making of and composition of formulations consisting of our PPC delivery polymer and nucleic acids.

These new patents further strengthen coverage of GEN-1, the Company's DNA-based immunotherapy in development for the localized treatment of ovarian cancer and glioblastoma multiforme (GBM), which is already covered by a composition of matter patent in the United States.

"Issuance of these patents further strengthens Celsion's growing position as a leader in the development of gene-based immunotherapies addressing some of the most difficult-to-treat cancers, such as ovarian cancer and GBM by covering the use of GEN-1 for treating solid tumors as a monotherapy and in combination with chemotherapy," said Michael H. Tardugno, chairman, president and CEO.  "GEN-1 leverages our proprietary TheraPlas™ technology platform, harnessing the power of IL-12 immunotherapy with a targeted delivery system engineered to overcome the limitations associated with the development of other dosage forms of IL-12 therapies."

About GEN-1

GEN-1 is being evaluated in an ongoing Phase 1b dose-escalating clinical trial (the "OVATION Study") combining GEN-1 with the standard of care for the treatment of newly diagnosed patients with advanced ovarian cancer who will undergo neoadjuvant chemotherapy followed by interval debunking surgery.  The OVATION Study is designed to enroll three to six patients per dose cohort at escalating doses of GEN-1 with the goal to identify a safe, tolerable and therapeutically active dose of GEN-1 by recruiting and maximizing an antitumor immune response.
