Portage invests in iOx Therapeutics, an United Kingdom-based cancer immunotherapy company

TORONTO, March 8, 2018 /PRNewswire/ - Portage Biotech Inc. ("Portage" or "the Company") (Canadian Securities Exchange: PBT.U, OTC Markets : PTGEF), is pleased to announce that it has made an investment in iOx Therapeutics, Ltd. ("iOx"), a United Kingdom-based immuno-oncology company. Portage will invest US$950,000 by subscribing to an unsecured, one-year convertible loan instrument. iOx will use the proceeds to complete the manufacturing of its lead candidate, IMM60, allowing the company to begin testing in humans later this year. The notes carry a 7% interest and will be priced at a discount to the next round of financing into the company. 

iOx was founded in February 2015 in order to develop a series of iNKT agonists that have been shown to inhibit the growth of tumors in several preclinical models of cancer. iOx has a clinical trial sponsorship agreement with Oxford University to conduct and fund (or arrange funding for) the first in human Phase I/II clinical trial for iOx's lead compound, both alone and in combination with anti-PD1 antibodies. iOx's second program, IMM65 (a nanoparticle formulation of IMM60 plus an NY-ESO-1 vaccine), is being developed with funding from the European Union's Horizon 2020 grant program (the PRECIOUS GRANT). Both compounds are potent approaches to priming and boosting an immune response in solid tumors with multiple Phase 1 and 2 trials funded by third party agreements. 

Professor Vincenzo Cerundolo, MD, PhD, iOx's scientific founder and the Director of the MRC Human Immunology Unit and Head of the RDM Investigative Medicine Division at the Weatherall Institute of Molecular Medicine at Oxford University, said "I am excited by the progress that iOx has made to advance its technology towards human testing.  The company looks forward to its collaborations with Oxford University and the PRECIOUS grant consortium to test its safety and benefit in cancer patients."

iOx CEO is Dr. Ian B. Walters, a Director of Portage, and Portage's CEO, Dr. Declan Doogan, serves as its chairman. "Portage continues to seek out attractive investment opportunities in which strong teams are developing compelling therapeutics for diseases with high unmet medical needs. iOx comes with a strong Board of Directors that we know, a very experienced C-Suite in Drs. Walters and Kramer, and a prolific founding scientist in Professor Cerundolo" said Greg Bailey, Chairman of Portage "also it is exciting that iOx's lead candidate is funded to enter the clinic in 10 months, and that it has the potential to greatly impact the cancer immunotherapy therapeutic landscape and help patients."

About iOx
Founded in February 2015 by Professor Cerundolo, iOx Therapeutics is a spin-out from the University of Oxford started to commercialize discoveries made as part of a long-running collaboration between Oxford and the Ludwig Institute for Cancer Research. iOx intends to develop and commercialize multiple synthetic lipid compounds discovered by a research team led by Professor Cerundolo.

Preliminary research indicates that these compounds activate invariant natural killer T-cells (iNKT cells), which, a large body of evidence suggests, play an important role in anti-tumor immune responses. iNKT cells are a distinct class of T lymphocyte displaying a limited diversity of T-cell receptors. They recognize lipid antigens on the surface of tumzr cells and produce large amounts of cytokines within hours of stimulation without the need for clonal expansion. Furthermore, iNKT cells activate multiple immune system components, including dendritic cells, T-cells and B-cells and stimulate an antigen-specific expansion of these cells.

About Portage
Portage is engaged in supporting the discovery and development of pharmaceutical and biotech products through clinical "proof of concept" with a focus on areas of unmet clinical need. Following proof of concept, Portage will seek to sell or license these products to large pharmaceutical or biotechnology companies for further development and commercialization. Portage has an interest in novel targeted therapies, stem cell therapies, and new indications for older marketed products that have been found to have novel patentable characteristics that bring new value to patients.
