About ORKA
Oruka Therapeutics, Inc. is a clinical-stage biopharmaceutical company. The Company is focused on developing novel monoclonal antibody therapeutics for psoriasis (PsO) and other inflammatory and immunology (I&I) indications. Its lead program, ORKA-001, is designed to target the p19 subunit of interleukin-23 (IL-23p19) for the treatment of PsO. Its co-lead program, ORKA-002, is designed to target interleukin-17A and interleukin-17F (IL-17A/F) for the treatment of PsO, psoriatic arthritis (PsA), and other conditions. ORKA-001 is an extended half-life monoclonal antibody (mAb) designed to target IL-23p19. IL-23 is a pro-inflammatory cytokine that plays a critical role in the proliferation and development of T helper 17 (Th17) cells, which are the primary drivers of several autoimmune and inflammatory disorders, including PsO. IL-23 is composed of two subunits: a p40 subunit and a p19 subunit. ORKA-002 is an extended half-life mAb designed to target IL-17A and IL-17F (IL-17A/F).
