Celsion Corporation Invited to Present Poster at Cytokine-Based Cancer Immunotherapies Summit

Celsion Corporation’s GEN-1 IL-12 Program in Advanced Ovarian Cancer to be Featured in Poster Presentation

Chief Science Officer Dr. Khursheed Anwer to Present and Participate in Two Panel Discussions

LAWRENCEVILLE, N.J., Nov. 29, 2021 (GLOBE NEWSWIRE) — Celsion Corporation (NASDAQ: CLSN), a clinical-stage development company focused on DNA-based immunotherapy and next-generation vaccines, announces that Khursheed Anwer, Ph.D., executive vice president and chief science officer, will be making a presentation on the Company’s GEN-1 interleukin 12 (IL-12) immunotherapy program at the Cytokine-Based Cancer Immunotherapies Summit being held in Boston on November 30 to December 2, 2021. Dr. Anwer’s presentation, titled “A Non-Viral Gene Therapy Approach to IL-12 Delivery for The Treatment of Cancer,” will be delivered on December 2 at 8:10 a.m. Eastern time. The Company was invited to submit a poster presentation which aligns with Dr. Anwer’s oral presentation on the GEN-1 IL-12 program. The poster presentation will contain a subset of his presentation slides. Dr. Anwer will also be participating in two panel discussions.

In his presentation, Dr. Anwer will be discussing how local delivery of IL-12 without significant systemic toxicity is feasible with a non-viral gene therapy approach that involves administration of an IL-12 plasmid with a synthetic DNA delivery system (GEN-1). Dr. Anwer will also be discussing how weekly intraperitoneal administration of GEN-1 yields durable increases in IL-12 and IFN-, and why repeated weekly administration of GEN-1 in combination with standard chemotherapy remodels the tumor immune environment to favor immune stimulation over immune suppression.

“We are pleased that the Cytokine-Based Cancer Immunotherapies Summit is recognizing Celsion’s leadership for and potential efficacy of cytokines as an immunotherapy for the treatment of serious malignancies,” said Michael H. Tardugno, chairman, president and chief executive officer of Celsion. “Results from the Company’s Phase I Study of GEN-1 in advanced ovarian cancer is attracting the interest of leading researchers in the field of immunotherapy.”

Dr. Anwer will also participate in two panel discussions:

• On December 1 at 8:30 a.m. Eastern time titled, “What Do We Know & Where Do We Want to Go?”
• On December 2 at 11:30 a.m. Eastern time titled “Side Effects – Mitigating Against Hypotension + Fever With Immune-Stimulating Agents (NK Cell Engagers, PD-1s, Cytokines, T-Cell Engagers) = Cytokine Release Syndrome (CRS)?”

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 that 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 anticancer immunity acting through the induction of T-lymphocyte and natural killer (NK) cell proliferation and maturation. The company previously reported positive safety and encouraging Phase I results with GEN-1 given as monotherapy or a combination therapy in patients with advanced peritoneally metastasized primary or recurrent ovarian cancer, and recently completed a Phase Ib dose-escalation trial (OVATION 1 Study) of GEN-1 in combination with carboplatin and paclitaxel in patients with newly diagnosed ovarian cancer. GEN-1 in combination with neoadjuvant chemotherapy is the subject of the ongoing randomized Phase II OVATION 2 Study in subjects with advanced-stage ovarian cancer (Stage III/IV), with enrollment now exceeding 75% and full enrollment targeted by the first half of 2022.
