About IO102-IO103
IO102-IO103 is an investigational off-the-shelf therapeutic cancer vaccine
designed to kill both tumor cells and immune-suppressive cells in the tumor microenvironment (TME) by stimulating activation and expansion of T cells against indoleamine 2,3-dioxygenase (IDO) positive and/or
programmed death-ligand 1 (PD-L1) positive cells. The company is currently conducting a pivotal Phase 3 trial (IOB-013/KN-D18;
NCT05155254) investigating IO102-IO103 in combination with pembrolizumab versus pembrolizumab alone in patients with advanced melanoma, a Phase 2 basket trial
(IOB-022/KN-D38; NCT05077709) investigating IO102-IO103 in combination with pembrolizumab as first line treatment in patients with solid tumors, and a Phase 2 basket
trial (IOB-032/PN-E40; NCT05280314) investigating IO102-IO103 in combination with pembrolizumab as neo-adjuvant/adjuvant
treatment of patients with solid tumors.
The clinical trials are sponsored by IO Biotech and conducted in collaboration with Merck, which is supplying
pembrolizumab. IO Biotech maintains global commercial rights to IO102-IO103.

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 pivotal clinical trial evaluating IO102-IO103 in combination with pembrolizumab versus pembrolizumab alone in patients with previously untreated, unresectable or metastatic (advanced) melanoma. A total of 407 patients have been enrolled from
more than 100 centers across the United States, Europe, Australia, Turkey, Israel and South Africa. The primary endpoint of the study is progression free survival, an event-driven analysis conducted when 226 events, defined as disease progression or
death, have been reported in the study. Secondary endpoints include overall response rate (ORR), overall survival (OS), durable objective response rate (DRR), complete response rate (CRR), duration of response (DoR), time to complete response
(TTCR), disease control rate (DCR), and incidence of AEs and SAEs (safety and tolerability). Biomarkers in the blood and tumor tissue will also be assessed. IO Biotech is sponsoring the Phase 3 trial and Merck is supplying pembrolizumab.
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.
