SOTIO and Cytune Pharma from the PPF Group, today presented new preclinical data highlighting the therapeutic potential of SO-C101, an IL-15 superagonist, as a monotherapy and in combination with PD-1 inhibitors in multiple tumor models. The data were presented in a virtual poster presentation at the 2020 American Association for Cancer Research (AACR) Virtual Annual Meeting II.
“SO-C101 is a highly promising modality in immuno-oncology given its ability to mobilize the two most important cell types driving anti-cancer immune responses, NK cells and CD8+ T cells. The preclinical data highlight the ability of SO-C101, an IL-15 receptor-β/γ superagonist, to reduce and prevent tumor growth in multiple mouse models through the control of these two immune cell types when given as a monotherapy and in combination with PD-1 inhibitors,” said Radek Špíšek, Chief Executive Officer of SOTIO. “We look forward to completing the monotherapy arm of our Phase 1/1b dose finding study in advanced solid tumors before the end of the year and initiating the dose escalation in combination with pembrolizumab in summer 2020.”
The virtual poster was entitled “SO-C101 displays strong anti-tumor effect in TC-1 and TRAMP-C2 tumor mice and in combination with PD-1 blockade prevents tumor development in an NK and CD8+ T cells dependent manner.” The data presented demonstrate the importance of NK and CD8+ T cells for the anti-tumor activity of SO-C101 as a monotherapy and in combination with PD-1 inhibition. Key findings presented include:
SO-C101 is currently being studied in a multicenter, open-label Phase 1/1b study (NCT04234113) to evaluate its safety and preliminary efficacy as monotherapy and in combination with pembrolizumab in patients with selected relapsed/refractory advanced/metastatic solid tumors.
