Lead investor Pfizer Inc. will collaborate on IGNITE’s new research program to help discover potential novel vaccinia viruses

Alameda, CA, December 12, 2016 — IGNITE Immunotherapy Inc. (IGNITE), a new company focused on oncolytic virus vaccine design, discovery and development today announced its formation. Along with strategic collaborative partner and lead investor Pfizer Inc. (NYSE: PFE), IGNITE will focus on the discovery and development of targeted and proprietary next-generation intravenous oncolytic (cancer cell lysing) virus vaccines for the immunotherapy of cancer. These biotherapeutics may be optimized for use in combination with immune checkpoint inhibitors. IGNITE is developing a robust and proprietary vector discovery platform, Oncolytic Vaccine Evolution, to potentially discover novel vectors for use in its lytic cancer vaccine products.

Key terms of the agreement with Pfizer include Pfizer holding a 50 percent equity investment in IGNITE, Pfizer providing full research and development funding for three years, and Pfizer having an exclusive option to acquire IGNITE after the initial research program is completed. Pfizer also has two seats on IGNITE’s board of directors. Financial terms were not disclosed.

“We are excited to announce the formation of IGNITE Immunotherapy, which we hope will emerge as a leader in the oncolytic virus cancer vaccine and immunotherapy fields. Our founding scientific team has deep expertise in the fields of oncolytic virus design and development, cancer immunotherapy, gene therapy and biotech entrepreneurship”, said Dr. David Kirn, co-founder and Executive Chairman of IGNITE. “I’m thrilled and honored to be working with my co-Founders and internationally-recognized scientific leaders Dr. David Schaffer and Dr. Douglas Hanahan. Together with our collaborators at Pfizer, we have highly complimentary skill sets that will help enable our success in this complex and promising field. Our mission is to create intravenous oncolytic cancer vaccines that will be safe and highly effective in combination with immune checkpoint inhibitors, which we hope will ultimately cure patients with metastatic cancers.”

“This partnership with IGNITE represents a significant advancement in Pfizer’s investment in oncolytic viruses, which we believe strengthens our position as a leader in next-generation immuno-oncology,” said James Merson, Ph.D., Chief Scientific Officer, Vaccine Immunotherapeutics at Pfizer and a member of IGNITE’s scientific advisory board and board of directors. “Pfizer has a strong and growing portfolio of immuno-oncology assets, and we remain committed to developing unique cancer therapies and novel combination therapies that may benefit patients around the world.

About IGNITE Immunotherapy Inc.
IGNITE is focused on the discovery and development of targeted oncolytic virus vaccines for the intravenous immunotherapy of cancer. IGNITE’s founding team, led by Drs. David Kirn (Executive Chairman), David Schaffer (SAB co-Chair) and Douglas Hanahan (SAB co-Chair), has deep expertise in oncolytic virus design and development, cancer immunotherapy, gene therapy vector discovery, experimental cancer therapeutics and biotech entrepreneurship. Our discovery platform, termed Oncolytic Vaccine Evolution, is designed to discover optimized gene and immunotherapy delivery vehicles to target cancer cells in diverse patient populations with common metastatic tumor types. These products may be designed for intravenous administration, antibody resistance, tumor-specificity and combination efficacy with immune checkpoint inhibitors.

About IGNITE’s Oncolytic Vaccine Evolution
Oncolytic virus cancer vaccines have demonstrated promising antitumoral activity and tolerability, and the oncolytic virus IMLYGIC (Amgen; talimogene laherperepvec) was approved by the US FDA in 2015 for the local treatment of unresectable cutaneous, subcutaneous and nodal lesions in patients with melanoma recurrent after initial surgery. While oncolytic viruses represent a promising new approach to cancer immunotherapy, hurdles to this approach still exist. First, IMLYGIC and many other clinical-stage agents require direct intratumoral injection, a method with significant disadvantages versus standard intravenous (IV) infusions that are used for blockbuster cancer biotherapeutics such as monoclonal antibodies (e.g. most patients with metastatic cancer have tumor metastases that are not directly injectable in the clinic). Second, if administered IV, many of these immunotherapeutic viruses are rapidly cleared by the immune system (e.g. by antibodies and/or complement). Finally, the number of immune-activating transgenes that can be expressed from the vector is limited by these viruses’ transgene-encoding capacities. Novel oncolytic vaccine vectors are needed for the IV delivery of diverse immunostimulatory transgenes to metastatic cancers.

IGNITE Immunotherapy is advancing the field of oncolytic cancer vaccines by taking advantage of evolution to help discover vectors that are designed to efficiently and selectively target cancer cells after IV administration. Our Oncolytic Vaccine Evolution platform empowers us to potentially discover and engineer optimized and proprietary oncolytic vectors for use in cancer immunotherapy. The resulting products may be evolved and designed for intravenous infusion, resistance to immune-mediated clearance (e.g. by antibodies, complement), tumor-specific replication and cell lysis, and immune-activating transgene expression.
