Celsion Announces Presentation of OVATION Study Findings at the Upcoming AACR Special Conference

Company to Report Final Clinical and Translational Research Data

LAWRENCEVILLE, N.J., Aug. 24, 2017 (GLOBE NEWSWIRE) -- Celsion Corporation (NASDAQ:CLSN), an oncology drug development company, today provided an update on its OVATION Study, a Phase Ib dose escalating clinical trial combining GEN-1, the Company's DNA-based immunotherapy, with the standard of care for the treatment of newly-diagnosed patients with advanced (stage III/IV) ovarian cancer who will undergo neoadjuvant chemotherapy followed by interval debulking surgery.  GEN-1 is an IL-12 DNA plasmid vector formulated as a nanoparticle in a non-viral delivery system to cause the sustained local production and secretion of the Interleukin-12 (IL-12) protein loco-regionally to the tumor site.   

The Company announced that an abstract for the OVATION Study has been accepted for presentation at the American Association for Cancer Research (AACR) Addressing Critical Questions in Ovarian Cancer Research and Treatment Special Conference, which will take place from October 1 - 4, 2017 at the Wyndham Grand Pittsburgh Downtown in Pittsburgh, PA.  

Celsion previously reported highly encouraging clinical data from the first fourteen patients who have completed treatment in the OVATION Study.  GEN-1 plus standard chemotherapy produced positive clinical results, with no dose limiting toxicities and promising dose dependent efficacy signals which correlate well with successful surgical outcomes as summarized below:

"We have completed enrollment of our OVATION Study in newly diagnosed ovarian cancer patients, one goal of which is to determine GEN-1's activity in combination with standard chemotherapy.  The remarkable surgical outcomes among all patients completing the prescribed eight weekly treatments reinforce our confidence in the promise of GEN-1's ability to work safely and effectively in advanced ovarian cancer," said Michael H. Tardugno, Celsion's chairman, president and CEO. "We have scheduled an Advisory Board Meeting in late September 2017 with our clinical investigators and scientific experts from the Roswell Park Cancer Institute and M.D. Anderson Cancer Center to review the clinical and translational research data from the OVATION Study in order to determine the next steps forward for this exciting new immunotherapy.  With the endorsement and recommendations from the Advisory Board, we fully expect to file a next phase protocol with FDA later this year."

OVATION Study Design

The Phase Ib trial will evaluate weekly intraperitoneal dosing of GEN-1 in combination with neoadjuvant chemotherapy, the standard of care for patients newly diagnosed with ovarian cancer. Concurrently with neoadjuvant chemotherapy, enrolled patients will receive escalating weekly doses of GEN-1, from levels beginning at 36mg/m², to 47mg/m², 61mg/m² and 79mg/m² weekly for 8 treatments in total, with interval debulking surgery to follow. The regimen will primarily be evaluated for its safety and tolerability.

About GEN-1 Immunotherapy

GEN-1, designed using Celsion's proprietary TheraPlas platform technology, is an IL-12 DNA plasmid vector encased in a nanoparticle delivery system, which enables cell transfection followed by persistent, local secretion of the IL-12 protein. IL-12 is one of the most active cytokines for the induction of potent anti-cancer immunity acting through the induction of T-lymphocyte and natural killer (NK) cell proliferation. The Company has previously reported positive safety and encouraging Phase I results with GEN-1 given as monotherapy in patients with peritoneally metastasized ovarian cancer, and recently completed a Phase Ib trial of GEN-1 in combination with PEGylated doxorubicin in patients with platinum-resistant ovarian cancer.
