IO Biotech Announces Acceptance of Abstracts to be Presented at the 2025 American Association for Cancer Research (AACR) Annual Meeting
Rhea-AI Summary
IO Biotech (IOBT) announced the acceptance of two abstracts for presentation at the 2025 AACR Annual Meeting in Chicago. The presentations will showcase new non-clinical data for their cancer vaccine candidates:
1. Data demonstrating how IO102-IO103, their lead candidate currently in Phase 3 trials for advanced melanoma, controls tumor growth through target-specific T-cell activation.
2. Preclinical data for IO170, their pipeline candidate targeting TGF-beta, showing promising antitumor activity.
Additionally, Dr. Mads Hald Andersen, the company's scientific co-founder, will chair and speak at an educational session on cancer vaccines, exploring the latest advances in cancer vaccine research.
Positive
- Lead candidate IO102-IO103 advancing in Phase 3 trial for advanced melanoma
- Promising preclinical data for pipeline candidate IO170 showing antitumor activity

Data tracked by StockTitan Argus on the day of publication.
• New non-clinical data strengthens evidence of contributions of IO102 and IO103 to tumor growth control through target specific T-cell activation, offering a distinct and complementary approach to checkpoint inhibitors
• New preclinical data for IO170 add to growing body of evidence supporting the potential of immune-modulatory therapeutic cancer vaccines to treat a wide range of cancers
NEW YORK, March 25, 2025 (GLOBE NEWSWIRE) -- IO Biotech (Nasdaq: IOBT), a clinical-stage biopharmaceutical company developing novel, immune-modulatory, off-the-shelf therapeutic cancer vaccines, today announced that two abstracts have been accepted for presentation at the American Association for Cancer Research (AACR) Annual Meeting 2025 taking place April 25-30 in Chicago, Illinois. One of the posters will share insights, using non-clinical models, related to IO Biotech’s lead investigational candidate, IO102-IO103, currently being evaluated in a pivotal Phase 3 trial in advanced melanoma. The second poster contains new preclinical data for the third candidate in the company’s pipeline, IO170, which targets transforming growth factor beta (TGF-beta). Additionally, Mads Hald Andersen, DMSc, PhD, Director of the Center for Cancer Immune Therapy (CCIT) and scientific co-founder of IO Biotech, will be chairing and speaking at an education session on cancer vaccines.
“We are pleased to share new data at AACR that expand our understanding of the underlying mechanism of action of our lead candidate, IO102-IO103, currently being investigated in a pivotal Phase 3 trial,” said Ayako Wakatsuki Pedersen, PhD, Senior Vice President of Translational Research at IO Biotech. “We are also excited to share that we have seen promising activity for an additional candidate being studied in our pipeline, IO170. Together, the data from both of these non-clinical studies further solidify the potential of our proprietary T-win immune-modulatory cancer vaccine platform.”
Dr. Pedersen continued, “We also look forward to the educational session on cancer vaccines, chaired by our scientific founder, that will explore the latest advances in cancer vaccine research and the distinct mechanisms of action of different approaches and their potential to reshape cancer immunotherapy.”

About IO Biotech
IO Biotech is a clinical-stage biopharmaceutical company developing novel, immune-modulatory, off-the-shelf therapeutic cancer vaccines based on its T-win® platform. The T-win platform is based on a novel approach to cancer vaccines designed to activate T cells to target both tumor cells and the immune-suppressive cells in the tumor microenvironment. IO Biotech is advancing its lead investigational cancer vaccine candidate, Cylembio® (imsapepimut and etimupepimut, adjuvanted) also known as IO102-IO103 in clinical trials, and additional pipeline candidates through preclinical development. Based on positive Phase 1/2 first line metastatic melanoma data, IO102-IO103, in combination with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), has been granted a Breakthrough Therapy Designation for the treatment of advanced melanoma by the US Food and Drug Administration. IO Biotech is headquartered in Copenhagen, Denmark and has US headquarters in New York, New York.
