Clinical Development Highlights
IO Biotech’s lead product candidate, IO102-IO103, has demonstrated promising results in clinical trials, positioning the company as a frontrunner in the development of innovative immune-modulating therapeutic cancer vaccines.
IO102-IO103 combines two fully owned, novel, off-the-shelf and immune-modulating vaccines, IO102 and IO103, which are designed to target indoleamine 2,3-dioxygenase (IDO) and programmed death ligand 1 (PD-L1) cells, respectively. In a single-arm Phase 1/2 clinical trial of 30 patients with metastatic melanoma, IO102-IO103 in combination with nivolumab, an anti-PD-1 checkpoint inhibitor, demonstrated proof of concept by increasing the overall response rate compared to what is typically reported with an anti-PD-1 antibody alone. The combination induced meaningful tumor regression and achieved rapid, deep and durable responses with a favorable tolerability profile.
Based on these results, IO102-IO103 in combination with pembrolizumab was granted Breakthrough Therapy Designation by the FDA for the treatment of unresectable or metastatic melanoma. IO Biotech is now conducting a global Phase 3 trial evaluating IO102-IO103 in combination with pembrolizumab as a potential first-line treatment in advanced melanoma patients.
In the pivotal Phase 3 trial (IOB-013/KN-D18) evaluating IO102-IO103 in combination with pembrolizumab as a first-line treatment for advanced melanoma patients, the Independent Data Monitoring Committee (IDMC) recently recommended that the trial continue without modifications after reviewing the safety and efficacy data. The primary endpoint of progression-free survival (PFS) is now projected to be reached in the first half of 2025.
Additionally, IO Biotech has reported positive results from its Phase 2 basket trial (IOB-022/KN-D38) evaluating IO102-IO103 in combination with pembrolizumab in the first-line treatment of advanced SCCHN. The study met its primary endpoint of overall response rate (ORR), and the data was presented at the European Society for Medical Oncology (ESMO) Congress 2024.
Furthermore, the company’s Phase 2 neoadjuvant/adjuvant basket trial (IOB-032/PN-E40) investigating IO102-IO103 in combination with pembrolizumab in patients with resectable melanoma and SCCHN has completed enrollment in the first cohort and expanded to include a randomized melanoma cohort.
IO Biotech is also advancing other product candidates in its pipeline. IO112, designed to target Arginase 1-expressing cells, has completed a Phase 1 trial in patients with solid tumors, showing no significant safety concerns and evidence of measurable peptide-specific immune responses. The company plans to submit an Investigational New Drug (IND) application for IO112 in 2025.
