IO Biotech Announces New Data Related to its IO102-IO103 Therapeutic Cancer Vaccine Presented Today at the IASLC 2023 World Conference on Lung Cancer
NEW YORK, Sept. 12, 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, announced that data from a pre-defined interim analysis related to the lung cohort of the Phase 2 basket trial (IOB-022/KN-D38) with IO102-IO103 in combination with KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy, as first-line therapy were presented today at the IASLC 2023 World Conference on Lung Cancer (WCLC). Jonathan Riess, MD, lead investigator of the trial at the UC Davis Comprehensive Cancer Center, presented encouraging early clinical and biomarker data supporting the combination treatment for patients with metastatic non-small cell lung cancer (NSCLC).
Dr. Riess commented, “We are encouraged that the clinical activity and safety profile continue to validate the potential of IO102-IO103 in combination with pembrolizumab to treat patients with metastatic NSCLC and PD-L1 TPS =50%. Available biomarker results for some patients show vaccine-specific T cell expansion and complete clearance or considerable drop of ctDNA, indicating activity of the treatment after just 21 days. With this interim analysis, where more than half of the evaluable patients had a partial response (8/15 patients or 53.3%), we are optimistic about the development of this potential therapy to help serve the unmet clinical need for improved treatment options for patients with advanced NSCLC.”
Abstract #2625: Ph 2 Trial of IO102-IO103 Vaccine Plus Pembrolizumab: Preliminary Results for the First-line Treatment of Lung Adenocarcinoma
As of the data cut-off in July 2023, 25 patients had been enrolled in the lung cohort of this basket trial. Included in today’s mini-oral presentation is data from the pre-defined interim analysis of the first 15 efficacy-evaluable patients who had received at least 2 full cycles of treatment, and either had at least 2 post-baseline tumor assessmens or discontinued. The data show that 8 of these 15 patients (53.3%), had a confirmed partial response (PR). The median duration of exposure is 15 weeks. The safety profile observed in this study are similar to past studies of IO102-IO103 in combination with pembrolizumab, which have demonstrated a profile consistent with pembrolizumab monotherapy with no noted additional significant systemic toxicity.
Qasim Ahmad, MD, Chief Medical Officer of IO Biotech, added, “We believe our cancer vaccine in combination with an anti-PD-1 antibody could change the treatment paradigm for multiple tumor types and this encouraging initial data show its potential as an efficacious and well-tolerated first-line treatment option for patients with NSCLC. We continue to enroll patients in the NSCLC cohort and the squamous cell carcinoma of the head and neck (SCCHN) cohort of this basket trial, and we look forward to reporting additional clinical and biomarker data over the next several months.”
The data were presented today in a mini oral presentation.

IO102-IO103 is an investigational immune-modulating cancer vaccine designed to target the immunosuppressive mechanisms mediated by the proteins indoleamine 2,3-dioxygenase (IDO) and PD-L1. The company is currently conducting a Phase 3 trial (IOB-013/KN-D18; NCT05155254) evaluating IO102-IO103 in combination with pembrolizumab in first-line advanced melanoma patients, and a Phase 2 basket trial (IOB-022/KN-D38; NCT05077709) evaluating IO102-IO103 in combination with pembrolizumab in first-line advanced non-small lung cancer and head and neck cancer.
About IOB-022/KN-D38 Phase 2 Solid Tumor Basket Trial
IOB-022/KN-D38, (NCT05077709) is a non-comparative, open label trial to investigate the safety and efficacy of IO102-IO103 in combination with pembrolizumab in patients with either non-small cell lung cancer (NSCLC) and squamous cell carcinoma of the head and neck (SCCHN). The clinical trial is sponsored by IO Biotech and conducted in collaboration with Merck. IO Biotech maintains global commercial rights to IO102-IO103.

About IO Biotech
IO Biotech is a clinical-stage biopharmaceutical company developing novel, immune-modulating cancer vaccines based on its T-win® vaccine platform. The T-win platform is a novel approach to cancer vaccines designed to activate T cells to target the most important immunosuppressive cells in the tumor microenvironment leading to the induction of a potent immune response within the TME to enhance the killing of tumor cells. IO Biotech is advancing in clinical trials its lead cancer vaccine candidate, IO102-IO103, targeting IDO and PD-L1, and through preclinical development its other pipeline candidates. IO Biotech is headquartered in Copenhagen, Denmark and has US headquarters in New York, New York.
