OSE Immunotherapeutics Presents a Poster on OSE-Cytomask®, a Novel “Cis-Demasking” Cytokine Technology to Increase Therapeutic Index of Immunocytokines
, a clinical-stage biotechnology company developing immunotherapies for cancer and autoimmune diseases, presents a poster on its novel OSE-Cytomask® Cis-Demasking immunocytokine technology at the Society for Immunotherapy of Cancer (SITC) 2025 Annual Meeting, taking place November 5–9, in National Harbor, Maryland.
OSE-Cytomask® platform is an innovative proprietary non-cleavable linker technology to create a new class of regulated and targeted cytokine therapeutics that enables precise cytokine activation on the appropriate T cell population, thereby improving the therapeutic index of immunocytokines. This innovative technology addresses a current unmet need in immunocytokine therapy by enabling the safe and targeted delivery of cytokines to tumor-specific T cell populations.
The poster presented highlighted how OSE-Cytomask® keeps cytokines inactive until they reach the right immune cells, specifically those expressing PD-1. This targeted activation helps avoid unwanted activation in healthy tissues and reduces side effects. Unlike other systems that rely on other biological agents to activate the cytokine, OSE-Cytomask® works independently of the tumor environment, offering enhanced stability and adaptability.
, said:
Immunocytokines are a new way to help the immune system fight cancer by sending special proteins (called interleukins) directly to tumors. When these proteins are combined with anti-PD-1 antibodies, they can activate the right immune cells—but sometimes they also affect the wrong ones, which can cause side effects and reduce their effectiveness. To solve this problem, OSE Immunotherapeutics created the OSE-Cytomask® platform. It uses a special design that keeps the protein inactive until it reaches the tumor, helping it work only where it's needed and making the treatment safer and more effective.
