NEW YORK, Nov. 01, 2023 (GLOBE NEWSWIRE) -- IO Biotech (Nasdaq: IOBT), a clinical-stage biopharmaceutical company developing novel, immune modulating cancer vaccines based on its T-win® technology platform, today announced three poster presentations at the Society for Immunotherapy of Cancer’s 38th Annual Meeting (SITC) being held in San Diego, California from November 1-5, 2023.
“The data presented provide clear evidence that our immune modulating vaccines, developed based on our T-win technology platform, impact several immune escape mechanisms as elegantly exemplified in abstract #1468,” said Mai-Britt Zocca, PhD, President and Chief Executive Officer of IO Biotech. “The data in this poster demonstrate enhanced in vivo anti-tumor effect when IDO and PD-L1 vaccines are co-administered in these models, further supporting the clinical observations regarding our lead investigational therapeutic vaccine candidate, IO102-IO103, which targets IDO and PD-L1. Data from clinical trials of IO102-IO103 administered with a PD-1 inhibitor demonstrated enhanced anti-tumor activity in multiple tumor types, including metastatic melanoma, non-small cell lung cancer and squamous cell cancer of the head and neck.”
Dr. Zocca continued, “Additionally, the arginase-1 data presented in abstract #1335 further demonstrate the potential of our T-Win® technology platform to generate additional vaccine candidates. Our T-Win technology vaccine candidates are designed to kill both tumor cells and immune suppressive cells in the TME, by stimulating activation of T cells against a particular target, such as arginase-1. Arginase-1 is expressed by multiple difficult-to-treat tumor types including colorectal and ovarian cancers.”
Abstract Number 1468: Peptide vaccination against PD-L1 reduces tumor growth in preclinical models through stimulation of PD-L1-targeting T cells in the tumor microenvironment
Presenter: Marion Chapellier, PhD, Senior Scientist, IO Biotech
Date and time: Saturday, November 4, 2023; poster session 11:55 am – 1:25 pm and poster reception 7:00 – 8.30 pm PDT
Abstract Number 1335: Arginase-1 vaccine promotes T cell immunity against arginase 1+ cells, controls tumor growth via immune modulation of tumor microenvironment
Presenter: Marco Carretta, PhD, Senior Scientist, IO Biotech
Date and time: Friday, November 3, 2023; poster session lunch 12:00 – 1.30 pm and poster reception 5:10 – 6:40 pm PDT
Abstract Number 1029: T Cell Receptor Diversity Analysis of in vitro-Expanded T cells Against IDO1 and PD-L1-Derived Peptides
Presenter: Preeyam Patel, PhD, Senior Scientist, IO Biotech
Date and time: Friday, November 3, 2023; poster session lunch 12:00 – 1.30 pm and poster reception 5:10 – 6:40 pm PDT

About IO102-IO103
IO102-IO103 is an investigational immune modulating therapeutic cancer vaccine designed to target the immunosuppressive mechanisms mediated by the proteins indoleamine 2,3-dioxygenase (IDO) and programmed death-ligand 1 (PD-L1). The company is currently conducting a pivotal Phase 3 trial (IOB-013/KN-D18; NCT05155254) evaluating IO102-IO103 in combination with pembrolizumab in first-line advanced melanoma patients, a Phase 2 basket trial (IOB-022/KN-D38; NCT05077709) evaluating IO102-IO103 in combination with pembrolizumab in first-line advanced non-small cell lung cancer and head and neck cancer (SCCHN), and a Phase 2 basket trial (IOB-032/PN-E40; NCT05280314) evaluating IO102-IO103 plus pembrolizumab as a perioperative treatment in solid tumors including melanoma and SCCHN.
The clinical trials are sponsored by IO Biotech and conducted in collaboration with Merck and Merck is supplying pembrolizumab. IO Biotech maintains global commercial rights to IO102-IO103.
