Roche and Inovio Pharmaceuticals partner on Inovio's prostate cancer and hepatitis B immunotherapy products

Sep 10, 2013

BASEL, Switzerland and BLUE BELL, Pa., Sept. 10, 2013 /PRNewswire/ -- Roche (SIX: RO, ROG; OTCQX: RHHBY) and Inovio Pharmaceuticals, Inc. (NYSE MKT: INO) announced today that they have entered into an exclusive worldwide license agreement to research, develop and commercialize Inovio's highly-optimized, multi-antigen DNA immunotherapies targeting prostate cancer and hepatitis B. The licensed compounds are currently in preclinical development and have generated robust T-cell responses in animal models.

Roche acquired an exclusive license for Inovio's DNA-based vaccines INO-5150 (targeting prostate cancer) and INO-1800 (targeting hepatitis B) as well as the use of Inovio's CELLECTRA® electroporation technology for delivery of the vaccines. Roche also obtained an option to license additional vaccine opportunities in connection with a collaborative research program in oncology.  Roche and Inovio will collaborate to further develop INO-5150 and INO-1800.

Under the terms of the agreement, Roche will make an upfront payment of USD $10 million to Inovio. Roche will also provide preclinical R&D support and payments for near-term regulatory milestones  as well as payments upon reaching certain development and commercial milestones potentially up to USD $412.5 million. Additional development milestone payments could also be made to Inovio if Roche pursues other indications with INO-5150 or INO-1800.  In addition, Inovio is entitled to receive up to double-digit tiered royalties on product sales.

Commenting on the deal, Hy Levitsky, Head of Cancer Immunology Experimental Medicine at Roche, said: "At Roche we are always interested in finding first-in-class and best-in-class therapies that may become the next generation treatments for patients with different types of cancer. INO-5150 will allow promising combination opportunities with the Roche portfolio, particularly with our emerging cancer immunotherapy molecules." Janet Hammond, Head of Infectious Diseases Discovery & Translational Area at Roche, added: "We are very excited to have this potentially very important and novel mechanism of action as part of our portfolio as we seek to address the significant unmet medical need in chronic hepatitis B infection."

"This partnership represents an important milestone in Inovio's growth and maturing product portfolio. Roche brings to our immunotherapy candidates its leadership position and track record for developing and marketing innovative first-in-class therapies," said Dr. J. Joseph Kim, Inovio's President and CEO. "Collaborating with the world's preeminent oncology development partner allows us to rapidly advance two of our promising near-clinical stage immunotherapy products from our product pipeline as we continue development of our phase II lead product, VGX-3100, for treatment of  HPV-related cancers and dysplasia."

About INO-5150 for Prostate Cancer
Inovio's dual-antigen synthetic DNA vaccine (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-based immunotherapy in animal studies and were similar to the immune responses generated by VGX-3100, Inovio's phase II-stage therapeutic HPV vaccine that generated best-in-class T-cell responses in a phase I study.

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 vaccine'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.

To provide worldwide rights to Roche, Inovio has re-acquired its hepatitis B, Asian-country rights from Inovio's international affiliate.

Disease Background

Prostate Cancer
Prostate cancer is the second most frequently diagnosed cancer of men. Nearly three-quarters of the registered cases occur in developed countries. Accounting for nearly 300,000 deaths each year, prostate cancer is the sixth leading cause of death from cancer in men. The development of a new treatment for prostate cancer would be a significant medical advancement given that present treatment options (surgery, radiation and hormone deprivation), while somewhat effective, all carry deleterious side effects and are often not a long-term cure.

Hepatitis B and Liver Cancer
Hepatitis B is a disease characterized by inflammation of the liver. The virus is extremely infectious – 100 times more so than HIV – and 400 million people are chronically infected worldwide. Hepatitis B contributes to an estimated 1 million deaths worldwide each year.

Liver cancer is the third most common cancer and the most deadly, killing most patients within five years of diagnosis. About 600,000 new cases arise each year. One of the major causes and risk factors for liver cancer is infection by hepatitis B.
