A clinical stage Biotech
XENOTHERA is a clinical stage biotech at the top of innovation, which creates new therapeutic modes in several indications. Our patented technological platform is built on our expertise in immunology and therapeutics. We develop innovative approaches in immunotherapy with our platform of Glyco-Humanized Polyclonal Antibodies (GH-pAb). Our antibodies are addressing major therapeutic needs in various domains, including oncology, immunosuppression, viral and bacterial infections. XENOTHERA’s platform allows short-time development thanks to our validated saled-up GMP platform, our in-house bioproduction facility, our clinical experience (400 patients have received GH-pAb today), our mastery of antigens and our regulatory experience. Within less than 8 years, XENOTHERA has brought to clinic LIS1, a novel induction treatment in Solid Organ Transplantation, addressing a $1Bn market, XAB05, a preventive anti- multidrug resistant bacteria GH-pAb, XAV19 an anti-COVID antibody dedicated to patients with moderate disease. XENOTHERA has accumulated preclinical evidence for the therapeutic effect of its oncology GH-pAbs. Two products will be in clinic in oncology in 2023, XON7, its lead pan-cancer targeting solid tumors and LIS22 in peripheral T-Cell lymphoma.
