Analysis · ORKA · Life Sciences
Oruka Therapeutics announced highly positive Week 16 data from its Phase 2a EVERLAST-A trial for ORKA-001 in moderate-to-severe psoriasis. The drug achieved its primary endpoint of PASI 100 (complete skin clearance) in 63.5% of patients, significantly outperforming placebo. Key secondary endpoints like PASI 90 and IGA 0 were also met with strong results. The favorable safety profile, consistent with its class, combined with updated Phase 1 data supporting potential once-yearly dosing, positions ORKA-001 as a potentially best-in-class treatment in a competitive market. This strong clinical validation significantly de-risks the program and could drive substantial investor interest, especially as the stock is currently trading near its 52-week high.
