Artiva Biotherapeutics ^{Filed, US Offering, Nasdaq: ARTV}

We are a clinical-stage biotechnology company focused on developing natural killer (NK) cell-based therapies for patients suffering from devastating autoimmune diseases and cancers. Our product candidates are derived from donor cells (allogeneic) rather than a patient’s own cells (autologous) and are pre-manufactured, stored frozen and ready to ship to a patient’s treatment location, making them what we believe to be “off-the-shelf.” Our lead product candidate, AlloNK, is a non-genetically modified, cryopreserved NK cell therapy being evaluated in combination with B-cell targeted monoclonal antibodies (mAbs) in an ongoing Phase 1/1b trial in class III or IV lupus nephritis (LN) and a basket investigator-initiated trial (IIT) in multiple autoimmune indications. Seminal peer-reviewed clinical studies using autologous CD19 chimeric antigen receptor (CAR) T-cell therapy (auto-CAR-T) for the treatment of autoimmune diseases have demonstrated that deep B-cell depletion in the periphery and in the lymphoid tissue can lead to drug-free disease remission. We have already demonstrated that AlloNK in combination with rituximab was able to drive deep B-cell depletion in the periphery and observed complete responses in heavily pre-treated patients naïve to auto-CAR-T in our ongoing Phase 1/2 clinical trial in patients with relapsed or refractory B-cell non-Hodgkin lymphoma (B-NHL).
