SOTIO Presents Data on SOT201 Immunocytokine and Other Programs at SITC Annual Meeting

SOTIO Biotech, a clinical-stage immuno-oncology company owned by PPF Group, today announced it will be presenting new preclinical data at the Society for Immunotherapy of Cancer's 38^th Annual Meeting taking place November 1-5, 2023 in San Diego, California.

Data to be presented include new preclinical results supporting the continued development of SOT201, a next-generation PD-1-inhibiting cytokine that SOTIO is progressing toward a planned first-in-human study in the second quarter of 2024. SOT201 is an antibody-cytokine fusion protein that could improve upon the efficacy of approved checkpoint inhibitors by combining PD-1 blockade with IL-15 immune stimulation in a single therapeutic construct.

Additional poster presentations at the meeting will include preclinical data on the synergistic effects of SOTIO's IL-15 superagonist in combination with CAR T-cell therapies, as well as data on SOTIO's IL-15 superagonist nanrilkefusp alfa.

Presentation details are as follows:
