ORKA-001

Successful go-public transaction and over $475 million raised this year provides cash runway through multiple clinical inflection points ORKA-001 non-human primate (NHP) pharmacokinetic and in vitro potency data, presented at EADV in September, further support and derisk the program Strong execution allowed for acceleration of clinical timelines for both ORKA-001 and ORKA-002, as previously announced MENLO PARK, Calif., Nov. 13, 2024 (GLOBE NEWSWIRE) -- Oruka Therapeutics, Inc. (“Oruka”) (Nasdaq: ORKA), a biotechnology company developing novel biologics designed to set a new standard for the treatment of chronic skin diseases including plaque psoriasis, today reported third quarter 2024 financial results and provided a corporate update. “We had a highly eventful third quarter which included going public, closing on over $475 million in proceeds across two transactions and continuing to progress our very promising co-lead programs,” said Lawrence Klein, PhD, Chief Executive Officer of Oruka. “We are excited to soon transition to a clinical stage company and show the potential of our programs to raise the bar on what is possible in psoriatic disease.” Third Quarter Business and Pipeline Updates Corporate Oruka consummated its go-public transaction and began trading on the Nasdaq under the ticker ORKA.The Company raised over $475 million, including a $275 million private placement previously announced in April that closed concurrently with the merger and an additional $200 million private placement shortly thereafter from a group of new and existing investors. ORKA-001: a novel half-life extended IL-23p19 monoclonal antibody Oruka plans to initiate a Phase 1 trial of ORKA-001 in the first quarter of 2025, which was accelerated from the first half of 2025. The Company expects to share interim data from the first-in-human trial in healthy volunteers, including initial pharmacokinetic data, in the second half of 2025 and initial efficacy data in psoriasis patients in the second half of 2026.Data presented at the European Academy of Dermatology and Venereology (EADV) Congress showed that ORKA-001 has a half-life in NHP of more than 30 days, over three times longer than risankizumab and one of the longest NHP half-lives observed for an extended half-life antibody. In addition, the data showed that ORKA-001 binds to a similar epitope as risankizumab and displays similar binding affinity and potency across a variety of in vitro assays.These findings support the potential for ORKA-001 to achieve extended dosing intervals of once every six months or even once a year while maintaining high antibody exposures and further derisk its development path. ORKA-002: a novel half-life extended IL-17A/F monoclonal antibody Oruka plans to initiate a Phase 1 trial of ORKA-002 in the third quarter of 2025, which was accelerated from the second half of 2025. The Company expects to share interim data from the first-in-human trial in healthy volunteers, including initial pharmacokinetic data, in the first half of 2026.A precursor antibody to ORKA-002 showed a half-life in NHP of approximately 20 days, double that seen with bimekizumab, supporting the potential to achieve significantly longer dosing intervals than currently marketed agents targeting IL-17. This extended half-life could enable a dosing interval of once every four to six months for ORKA-002. Third Quarter 2024 Financial Results Cash Position: As of September 30, 2024, Oruka had available cash and cash equivalents of $410.9 million. Net cash used in operating activities was $27.8 million for the third quarter of 2024. The Company expects this cash to provide runway through 2027. Research and Development (R&D) expenses: R&D expenses totaled $25.7 million for the third quarter of 2024. This expense includes $7.8 million of non-cash stock-based compensation. During the third quarter of 2024, the Company incurred $11.8 million and $4.1 million on the development of ORKA-001 and ORKA-002, respectively. General and Administrative (G&A) expenses: G&A expenses totaled $3.8 million for the third quarter of 2024. This expense includes $2.4 million of personnel-related costs, including $1.2 million of non-cash stock-based compensation related to equity awards to employees and service providers, and $1.3 million for professional, consulting, and other costs to operate a public company and support R&D activities. Other income (expense): Other income, net for the third quarter of 2024 was $0.8 million. Interest earned on the Company’s investment in money market funds was $1.3 million for the third quarter of 2024, partly offset by interest expense of $0.5 million on convertible notes before their conversion to common stock. Net loss: Net loss totaled $28.6 million for the third quarter of 2024, which includes non-cash stock-based compensation of $9.0 million. Shares Outstanding: Oruka has approximately 55.1 million shares of the Company’s Common Stock and Common Stock equivalents issued and outstanding, including shares of Common Stock underlying pre-funded warrants and Series A and Series B non-voting convertible preferred stock.
