(“Oruka”) (Nasdaq: ORKA), a clinical-stage biotechnology company developing novel biologics designed to set a new standard for the treatment of chronic skin diseases including plaque psoriasis, today reported second quarter 2025 financial results and provided a corporate update. “We are very pleased to have initiated our EVERLAST-A study, and we expect nearly all our sites to be open and enrolling by the end of the month,” said Lawrence Klein, PhD, Chief Executive Officer of Oruka. “This study could demonstrate three different aspects of ORKA-001’s differentiation – an ultra-long dosing interval, higher efficacy than other IL-23 inhibitors, and the potential for off-treatment remissions. Together with our ORKA-002 program and ORKA-021 sequential combination that are following close behind, we are confident we can have the best biologic regimens in psoriatic disease, an area that continues to reward innovation in biologics.” Second Quarter Business and Pipeline Updates ORKA-001: a novel half-life extended IL-23p19 monoclonal antibody Enrollment is ongoing in EVERLAST-A following clearance from both the U.S. FDA and Health Canada in July, and the first patients have been dosed in the study. EVERLAST-A is a randomized, double-blind, placebo-controlled Phase 2a trial designed to enroll approximately 80 patients with moderate-to-severe plaque psoriasis. Patients will be randomized 3:1 to receive ORKA-001 or placebo with a primary endpoint of PASI 100 at Week 16. At Week 28, patients who have achieved PASI 100, or completely clear skin, will be randomized 2:1 to either (1) an arm where they do not receive another dose until disease recurs or (2) ORKA-001 every six months. This “no-dose” arm will provide evidence for both yearly dosing and the potential for extended off-treatment remissions. Additional details on the EVERLAST-A design will be presented at the European Academy of Dermatology and Venereology (EADV) Congress in September. The Company expects to share efficacy and response duration data from EVERLAST-A in 2H 2026. Psoriasis trials historically have low placebo rates and high reproducibility across phases of development, making this Phase 2a readout particularly impactful for demonstrating ORKA-001’s differentiation.Oruka’s Phase 1 trial of ORKA-001 is ongoing, with dosing completed for all 24 subjects across three dose levels. The trial is a double-blind, placebo-controlled, single ascending dose study evaluating the safety, tolerability, and pharmacokinetics (PK) of ORKA-001. The Company will present data from this trial at EADV in September. ORKA-002: a novel half-life extended IL-17A/F monoclonal antibody The first participants were dosed in a Phase 1 trial of ORKA-002 in May, and the trial is ongoing. The trial is a double-blind, placebo-controlled, single ascending dose study evaluating the safety, tolerability, and PK of ORKA-002 in approximately 24 healthy volunteers. The Company expects to share interim data from this trial, including initial PK data, around YE 2025, and to initiate a Phase 2 trial in psoriasis in 1H 2026. Additional programs and updates Laura Sandler, who joined Oruka in 2024 as SVP of Operations, was promoted to Chief Operating Officer.ORKA-021 (ORKA-002 → ORKA-001): Oruka continues to advance a sequential combination regimen of ORKA-002 and ORKA-001, which could deliver rapid and deep responses with an ideal maintenance profile. ORKA-021 could create another opportunity for the Company to define the best possible regimen for the treatment of psoriatic disease.ORKA-003: The Company continues to progress ORKA-003 through preclinical development.
