About the IOB-013/KN-D18 Pivotal Phase 3 Clinical Trial
IOB-013/KN-D18 (Clinical Trials.gov: NCT05155254) is an open label, randomized Phase 3 clinical trial of IO102-IO103 in combination with pembrolizumab versus pembrolizumab alone in patients with previously
untreated, unresectable or metastatic (advanced) melanoma, being conducted in collaboration with Merck. Patients have been enrolled from centers across the United States, Europe, Australia, Turkey, Israel and South Africa. The primary endpoint of
the study is progression free survival. Biomarker analyses will also be conducted. IO Biotech is sponsoring the Phase 3 trial and Merck is supplying pembrolizumab. IO Biotech maintains global commercial rights to IO102-IO103.
About the IOB-013/KN-D18 Clinical Trial Endpoints
The primary endpoint of the IOB-013/KN-D18 trial is progression
free survival (PFS). The PFS analysis is event-driven and will be conducted when 226 events have occurred in the trial, which the company estimates will take place in the first half of 2025. Additionally, there is a planned per-protocol interim analysis of overall response rate when the first 225 randomized patients reach one year of treatment in mid-2024. The outcome of this analysis is expected
in the third quarter of 2024. There is a high statistical bar for the Phase 3 interim analysis (p≤0.005), which was set to preserve most of the alpha for the primary endpoint of PFS. Regardless of the outcome of the interim analysis, the trial
is designed to continue to the primary PFS endpoint.
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 first-line advanced cancers in non-small cell lung cancer (NSCLC) and squamous cell carcinoma of the head and neck (SCCHN). IO Biotech is sponsoring the Phase 2 trial and
Merck is supplying pembrolizumab. IO Biotech maintains global commercial rights to IO102-IO103.
About IOB-032/PN-E40 Phase 2 Solid Tumor Basket Trial
IOB-032/PN-E40 (NCT05280314) is a Phase 2 basket trial investigating the IO102-IO103 therapeutic cancer vaccine in combination with pembrolizumab as
neo-adjuvant/adjuvant treatment of patients with solid tumors. The study will enroll approximately 15 patients with melanoma and 15 patients with SCCHN in cohort A and cohort B respectively as single arm
cohorts receiving combination of IO102-IO103 with pembrolizumab, whereas in cohort C ≥30 melanoma patients will be randomized 1:1 to neo-adjuvant treatment with either the combination of IO102-IO103 with
pembrolizumab or pembrolizumab alone. In the neo-adjuvant period, for all cohorts, treatment is every 3 weeks (Q3W) for 3 cycles
