Sairopa is a clinical-stage company that develops novel treatments for cancer by modulating the patient’s immune system. Cancer treatment was revolutionized by the introduction of so-called immune checkpoint inhibitors, that enhances the immune response against the patient’s own tumor. However only about 30% of cancer patients find benefit from such therapies. It is well accepted that for a productive anti-cancer immune response to happen, all elements of the cancer-immunity cycle need to be functional: tumor-antigen release, antigen-processing, -presentation, T-cell activation and blockade of local immunosuppression in the tumor.
Early 2021 Sairopa acquired, backed by Van Herk Investments, a portfolio of therapeutic antibodies from Chinook Therapeutics. These antibodies were originally developed by BioNovion/Aduro Biotech Europe using the proprietary B-Select antibody platform that was also used to identify pembrolizumab (Keytruda™), BION-1301 and MK-5890 (Guelen et al., 2022).
It is Sairopa’s mission to develop agents that can modulate this cancer-immunity cycle on different points:
ADU-1805, Sairopa’s proprietary anti-SIRPalpha antibody is enhancing tumor cell uptake and presentation to the T cells to induce priming and activation (Voets et al., 2019).
ADU-1604, Sairopa’s proprietary and unique anti-CTLA4 antibody is enhancing T cell priming and activation to raise a higher diversity of tumor cytotoxic immune cells. ADU-1604 is currently being tested in Phase 1 Clinical trials to assess for safety and efficacy in patients suffering from advanced melanoma.
