Inovio Pharmaceuticals to Independently Develop Prostate Cancer Immunotherapy; Will Maintain Collaboration and License Agreement with Roche for Inovio's Hepatitis B Immunotherapy

Nov 17, 2014

PLYMOUTH MEETING, Pa., Nov. 17, 2014 /PRNewswire/ -- Inovio Pharmaceuticals, Inc. (NASDAQ: INO) announced today the company and Roche have terminated their 2013 collaboration, option, and license agreement to co-develop INO-5150, Inovio's DNA immunotherapy targeting prostate cancer, as well as their research collaboration in prostate cancer. All of Roche's rights to INO-5150, including the right to license the product to other parties, will be returned to Inovio.  Inovio plans to independently advance INO-5150 into a phase I clinical trial in the first half of 2015.

Inovio and Roche will continue to collaborate and co-develop Inovio's DNA immunotherapy (INO-1800) against hepatitis B virus under their existing license agreement. The partnership is on track to move INO-1800 collaboratively into a phase I study in 2015.

Dr. J. Joseph Kim , Inovio's president & CEO, said, "The Inovio/Roche partnership will continue to thrive focusing on the development of INO-1800 for the treatment of hepatitis B. In addition to recently demonstrating clinical efficacy and the ability to induce potent antigen specific CD8+ T cell responses in our VGX-3100 phase II study, Inovio will be moving a broad portfolio of immuno-oncology products through development, including INO-3112 (head/neck and cervical cancers), INO-1400 (breast, lung and pancreatic cancers) and INO-5150 (prostate cancer). We believe that these products along with pre-phase III VGX-3100 will further our growth and represent opportunities for additional value-adding partnerships."

About INO-5150 for Prostate Cancer
Inovio's dual-antigen synthetic DNA immunotherapy (INO-5150) targets prostate-specific membrane antigen (PSMA) and prostate-specific antigen (PSA). A study in monkeys showed that vaccination with INO-5150 generated strong and robust T-cell immune responses that were the highest generated by a PSA-targeting immunotherapy in animal studies and were similar to the immune responses generated by VGX-3100, Inovio's phase II-completed HPV immunotherapy that generated best-in-class T-cell responses.

Inovio's SynCon® DNA vaccine for prostate cancer was designed with PSA and PSMA synthetic consensus immunogens based on human and macaque sequences, resulting in amino acid sequences that differ slightly from the native human protein. In humans, this novel approach is utilized to help the body's immune system recognize cancerous cells created in the body as 'foreign', overcoming the body's self-tolerance of these cells and mounting an immune response to clear them.

About INO-1800 for Hepatitis B
Inovio has reported preclinical data showing its hepatitis B vaccine (INO-1800) generated strong T-cell and antibody responses that led to the elimination of targeted liver cells in mice. These results indicate this DNA immunotherapy's potential to treat hepatitis B infection and prevent further development of the infection into liver cancer in humans.

In a preclinical study, researchers found the vaccine-specific T-cells exhibited a killing function, and could migrate to and stay in the liver and cause clearance of target cells without evidence of liver injury. This was the first study to provide evidence that intramuscular immunization can induce killer T-cells that can migrate to the liver and eliminate target cells.
