Share of revenueClinical-stage antibody program targeting IL-23p19 for psoriasis.
Clinical-stage antibody program targeting IL-17A/F for psoriasis, HS, and related I&I diseases.
Earlier-stage undisclosed pathway program for inflammatory dermatology and I&I expansion.
Exclusive worldwide rights to develop and commercialize licensed antibody programs.
Customers
Oruka does not yet sell commercial products; its near-term counterparties are clinical trial sites, contract research organizations, contract manufacturers, and other development partners that support its pipeline. If approved, its eventual customers would be physicians, hospitals, and specialty pharmacies serving patients with psoriasis, hidradenitis suppurativa, psoriatic arthritis, and related inflammatory diseases.
CROs, investigators, labs, and CMOs that execute studies and supply drug material.
Physicians treating psoriasis, HS, PsA, and other inflammatory conditions if products are approved.
Hospitals, specialty pharmacies, and distributors that would handle commercial access.
Strategy
Oruka’s strategy is to focus on a small number of differentiated antibody programs in inflammatory dermatology, using validated biology and half-life extension to improve dosing convenience. It seeks to advance ORKA-001 and ORKA-002 through clinical development while preserving optionality for future commercialization or strategic collaboration.
Clinical proof-of-concept is the main value driver for a pre-commercial biotech.
Longer dosing intervals can improve adoption versus existing biologics.
A flexible go-to-market model can maximize value if programs succeed.
Geography
Oruka is headquartered in Menlo Park, California and operates as a U.S.-based development company. Its programs are intended for the United States and other key markets, and its clinical and regulatory work can extend into foreign jurisdictions through global trial and licensing activities.
Risks
Oruka is a clinical-stage company with no approved products, so its value depends on successful trial outcomes, regulatory clearance, and eventual manufacturing scale-up. It also relies on third parties for research, manufacturing, and supply, while its licensed programs carry milestone and royalty obligations to Paragon.
