FDA Awards $1.6M Orphan Drug Grant for Clinical Phase II Development of EGEN-001 for Treatment of Ovarian Cancer

EGEN, Inc. announced that the Food and Drug Administration (FDA) awarded the company a four-year grant of $1.6 million to assist in the phase II clinical development of EGEN-001, the company’s lead product. EGEN-001 is under clinical development for the treatment of advanced recurrent ovarian cancer.

EGEN-001 was developed as an interleukin-12 (IL‑12) gene therapy for the treatment of disseminated epithelial ovarian cancer. It is a low concentration formulation composed of a human IL-12 plasmid formulated with a proprietary PPC delivery system. EGEN-001 is designed for intraperitoneal (IP) administration. The subsequent IL-12 protein expression is associated with an increase in immune system activity, including T-lymphocyte and natural killer (NK) cell proliferation, and cytotoxic activation and secretion of interferon gamma (IFN-g), which in turn, leads to tumor inhibition. Additionally, IL-12 inhibits angiogenesis and formation of tumor vascularization.

EGEN has successfully completed two Phase I trials of EGEN-001 in ovarian cancer patients.  In the first study, EGEN-001 was administered as monotherapy in platinum-resistant ovarian cancer patients[2] and in the second study in combination with carboplatin/docetaxel chemotherapy in platinum-sensitive ovarian cancer patients.[3] In both studies, EGEN-001 treatment resulted in good safety, biological activity and encouraging efficacy.[4-5] EGEN-001 received Orphan Drug Status from the FDA in 2005, and its first $1 million FDA orphan grant in 2005.

“This is a significant milestone and accomplishment for the company,” commented Dr. Khursheed Anwer, President and Chief Science Officer of EGEN. “We are pleased to receive this FDA support, which has been very useful in the advancement of our novel EGEN-001 product in the clinic for the treatment of recurrent ovarian cancer. The product utilizes the Company’s proprietary TheraPlas® delivery technology and is composed of interleukin-12 (IL-12) gene formulation with a biocompatible delivery polymer. IL-12 is a potent cytokine which works by enhancing the body’s immune system against cancer and inhibiting tumor blood supply.”
