Insights

Financial Analyst

Oruka Therapeutics' latest financial report demonstrates strong financial positioning for a clinical-stage biotech company. The $394 million cash position at year-end 2024 provides a substantial runway through 2027, extending well beyond their anticipated ORKA-001 Phase 2a data readout. This financial cushion significantly de-risks the company's near-term development plans.

The company's successful public market debut and ability to raise $475 million in 2024 through oversubscribed private placements signals strong investor confidence in their pipeline and strategy. This level of capitalization is especially noteworthy for a company in its first year of operations.

While quarterly net losses of $25.8 million and inception-to-date losses of $83.7 million are substantial, they're proportionate to the R&D-intensive nature of the business at this stage. The $25.5 million Q4 R&D investment demonstrates appropriate allocation toward value-creating clinical programs, with the pace of cash burn ($18.8 million in Q4) suggesting disciplined capital deployment.

The company's projected clinical timeline, with data readouts approximately every six months starting in 2H 2025, creates a steady cadence of potential value-inflection points. Their financial runway extending more than a year beyond the pivotal Phase 2a data for ORKA-001 provides negotiating leverage should they pursue partnerships and insulates them from near-term capital market pressures.

Biotechnology Expert

Oruka's pipeline strategy shows a sophisticated approach to dermatological biologics. Their lead candidate ORKA-001 targets IL-23p19, the same mechanism as Skyrizi (risankizumab), but with potential pharmacokinetic advantages. The non-human primate data showing a half-life three times longer than risankizumab suggests potential for significantly extended dosing intervals - possibly once every six months versus the current quarterly standard.

The Phase 2a trial design is particularly noteworthy with its ambitious PASI 100 primary endpoint (complete skin clearance) versus the industry-standard PASI 90. This signals confidence in their product's efficacy and aligns with evolving treatment goals in psoriasis management. The inclusion of arms testing six-month dosing and treatment-free observation periods could differentiate ORKA-001 in a competitive market.

The reference to the KNOCKOUT trial data, showing 44% of patients maintaining complete clearance one year after their last risankizumab dose, provides external validation for their strategic approach of pursuing extended response durations.

Similarly, ORKA-002's targeting of IL-17A/F with extended half-life positions it against competitors like Taltz and Cosentyx, but with potential dosing advantages. The sequential regimen approach (ORKA-021) demonstrates forward thinking about combination strategies that could address both rapid onset and sustained response needs simultaneously.

The company's timeline of clinical catalysts every six months creates a steady stream of potential validation points for their platform and specific assets.

$394 million of cash, cash equivalents, and marketable securities at year-end 2024, projected to fund company through 2027, over one year past anticipated ORKA-001 Phase 2a data in psoriasis

MENLO PARK, Calif.,, March 06, 2025 (GLOBE NEWSWIRE) -- Oruka Therapeutics, Inc. (“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 fourth quarter and full year 2024 financial results and provided a corporate update.

“We made tremendous progress in our first year as a company, including our successful public debut, raising over $475 million to fund the company through 2027, and advancing ORKA-001 into the clinic,” said Lawrence Klein, PhD, Chief Executive Officer of Oruka. “As we move into 2025, we are excited about the momentum ahead, with our first clinical data readout anticipated later this year as well as our plans to advance ORKA-002 into the clinic and ORKA-001 into Phase 2 development. Looking forward, we expect to deliver a clinical catalyst every six months, which could progressively establish ORKA-001 and ORKA-002 as the best treatment options in the incredibly important therapeutic area of psoriatic disease.”

Fourth Quarter and Full Year Business and Pipeline Updates

ORKA-001: a novel half-life extended IL-23p19 monoclonal antibody

• Oruka initiated a Phase 1 trial of ORKA-001 in December 2024, ahead of schedule. The trial is a double-blind, placebo-controlled, single ascending dose study evaluating the safety, tolerability, and pharmacokinetics (PK) of ORKA-001 in approximately 24 healthy volunteers. The Company expects to share interim data from this trial, including initial PK data, in the second half of 2025.
• Oruka plans to initiate a Phase 2a proof-of-concept study of ORKA-001 in the second half of 2025 that will enroll approximately 80 patients with moderate-to-severe psoriasis. The planned study design is innovative, with a primary endpoint of PASI 100 at week 16 (versus PASI 90 for prior biologics studies) and maintenance arms evaluating a six-month dosing interval alongside a cohort of patients who are not re-dosed until disease recurrence to test the potential for ultra-long responses. The Company expects to share efficacy and response duration data from this study in the second half of 2026. Psoriasis trials historically have had low placebo rates and good reproducibility across phases of development, making this Phase 2a readout particularly impactful for derisking ORKA-001.
• Preclinical data presented at the European Academy of Dermatology and Venereology (EADV) Congress in September 2024 showed that ORKA-001 has a half-life in non-human primates (NHPs) 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 longer.
• Updated long-term data from KNOCKOUT, an investigator-initiated trial evaluating high induction doses of risankizumab, was presented in December 2024 and showed that ~44% of patients retained PASI 100 at one year and ~10% retained PASI 100 at two years despite receiving their last dose at week 16. This data demonstrates the potential for longer term "remission"-like responses following treatment with a higher dose IL-23 inhibitor. The Company believes that ORKA-001 can build on these results and potentially enable long-lasting responses in a significant portion of patients.

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. The Company expects to share interim data from the first-in-human trial in healthy volunteers, including initial PK data, in the first half of 2026.
• Preclinical data on ORKA-002 will be presented at the American Academy of Dermatology (AAD) Annual Meeting this month. ORKA-002 has the potential to achieve extended dosing intervals of once every four to six months, significantly longer than currently approved therapies targeting IL-17.

Title: #64919 Characterization of ORKA-002, a Novel Extended Half-Life Monoclonal Antibody Targeting IL-17A/F for the Treatment of Psoriasis and Other Indications
Presentation Information: 8:30am ET, Friday, March 7, 2025

Additional programs

• ORKA-021: Oruka disclosed a new 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 in psoriatic disease.
• ORKA-003: The Company is on track to disclose additional program details in the first half of 2025.

Corporate

• Oruka successfully completed its go-public transaction and began trading on the Nasdaq under the ticker ORKA. As part of this process, the Company raised over $475 million in 2024, including two oversubscribed private placements of $275 million and $200 million, respectively. The Company has cash runway through 2027, over one year past anticipated Phase 2a data for ORKA-001 in plaque psoriasis.
• Oruka entered into license agreements with Paragon Therapeutics granting it worldwide exclusive rights to ORKA-001 in all indications other than inflammatory bowel disease, and to ORKA-002 in all indications.
