About Us

iOx Therapeutics (iOx) is a near clinical stage biotechnology company developing a series of synthetic lipid compounds to prime and boost an immune response in cancer patients by stimulating invariant natural killer T cells (iNKT). The Company’s two lead compounds, IMM60 and IMM65, are expected to enter the clinic in the next year.

Portage owns approximately 60% of iOx. Portage serves as Chief Executive Officer, Chief Scientific Officer, and provides project management and financial roles. In addition, Portage holds the Chairman and executive member seats on the Board of Directors.

iOx Therapeutics plans to develop a pipeline of iNKT agonists, which have been shown to inhibit the growth of tumors as a monotherapy in preclinical studies. Through the Company’s clinical trial sponsorship agreement with Oxford University, we are going to conduct both Phase 1 and Phase 2 trials for its lead product candidate, IMM60, alone and in combination with anti-PD1 antibodies. iOx’s second product candidate, IMM65, a nanoparticle co-formulation of IMM60 plus an NY-ESO-1 vaccine, received funding from the European Union’s Horizon 2020 grant program (the PRECIOUS GRANT) to cover the development, manufacturing and planned phase I/II clinical studies.

iNKT are a distinct type of immune cell that bridges the innate and adaptive immune systems. IMM60 is designed to optimally engage the T cell receptor on the iNKT, and facilitate its binding to the CD1d molecule on dendritic cells, resulting in the secretion of a large amount of cytokines. This leads to activation and expansion of important immune system components, which primes and boosts an adaptive immune attack against cancer. Preclinical studies have validated that the Company’s iNKT agonists inhibit tumor growth.

The products and concepts of iOx are based on the pioneering work of Dr. Vincenzo Cerundolo, who tragically lost his battle with cancer too early to see his work being tested in patients.
