About iNKT Agonists PORT-2 and PORT-3
PORT-2 and PORT-3 contain small molecule agonists (IMM60) of invariant natural killer T-cells (iNKT cells) developed by the University of Oxford, which play an important role in anti-tumor immune responses. iNKT cells are a distinct class of T lymphocytes and recognize lipid antigens on the surface of the tumor. Our synthetic iNKT agonists are designed to optimally engage the T-cell receptor on the iNKT and facilitate its binding to dendritic cells, resulting in the secretion of a large amount of pro-inflammatory cytokines. This leads to the activation and expansion of important immune system components and primes and boosts an adaptive immune attack against cancer. We see that monotherapy treatment with iNKT agonists shows a heightened immune response and better cancer control in animal models that are resistant to PD-1 antibody treatment. Combination therapy with PD-1 antibodies is synergistic with iNKT agonists and restores sensitivity to PD-1 blockade. While treatment with iNKT agonists alone shows promising preclinical activity against cancer, data suggests that when an iNKT agonist is co-packaged with tumor-specific antigens, potency is increased by up to 5x. PORT-2 is a liposomal formulation of our IMM60 iNKT agonist while PORT-3 is a co-formulation of our IMM60 iNKT agonist with an NY-ESO-1 peptide vaccine, co-packaged into a nanoparticle.
Portage is a clinical-stage immuno-oncology company advancing first-in-class therapies that target known checkpoint resistance pathways to improve long-term treatment response and quality of life in patients with evasive cancers. The Company’s access to next-generation technologies coupled with a deep understanding of biological mechanisms enables the identification of the most promising clinical therapies and product development strategies that accelerate these medicines through the translational pipeline. Portage’s portfolio consists of five diverse platforms, leveraging delivery by intratumorals, nanoparticles, liposomes, aptamers, and virus-like particles. Within these five platforms, Portage has 10 products currently in development with multiple clinical readouts expected over the next 12-24 months.
