SOTIO will present three posters discussing data that highlight the encouraging safety and efficacy for SOT101 (SO-C101) as a monotherapy and in combination with pembrolizumab for the treatment of advanced solid tumors.
SOTIO Biotech, a clinical stage immuno-oncology company owned by PPF Group, today announced that it will present three posters highlighting new clinical data on SOT101 at the Society for Immunotherapy of Cancer (SITC) 36th Annual Meeting to be held virtually and in person, from November 10-14, 2021 in Washington, D.C.
SOT101 is an interleukin 15 (IL-15) superagonist currently being evaluated in an open-label Phase 1/1b study to evaluate the safety and preliminary efficacy as a monotherapy and in combination with pembrolizumab in patients with selected relapsed/refractory advanced/metastatic solid tumors. Details on the upcoming presentations are below:

SOT101 (formerly SO-C101 or RLI-15) is a subcutaneously-administered IL-15 superagonist that is fused to the sushi+ domain of the IL-15 receptor α chain. SOT101 has demonstrated strong preclinical in vivo efficacy in various tumor models showing increased long-term survival and tumor regression, as well as a favorable toxicology profile. SOT101 has been shown in pre-clinical models to synergize with checkpoint inhibitors and antibody therapies exerting ADCC.
