ImmunOs Therapeutics AG is a company based in Schlieren, Switzerland that pioneers HLA-based therapeutics to create transformational medicines for cancer and inflammation. The Swiss company has identified specific HLA molecules that activate the immune system and is utilizing these molecules as the backbone of novel therapies capable of stimulating both the innate and adaptive immune systems of cancer patients to eliminate tumor cells. ImmunOs' lead program is a multi-functional fusion protein that blocks specific LILRB and KIR receptors and activates anti-tumor responses. The company is also using HLA molecules to develop novel therapies to treat inflammatory diseases. ImmunOs is supported by leading international investors, including Samsara BioCapital, Lightspeed Venture Partners, Gimv, Pfizer Ventures, Biomed Partners, Schroder Adveq, Mission BioCapital, GL Capital, Peak6, Fiscus, and Redalpine.
