– Continued to advance three clinical programs, including global Phase 3 ONWARD clinical trials for ESK-001 in moderate-to-severe plaque psoriasis, Phase 2b clinical trial for ESK-001 in systemic lupus erythematosus (SLE) and Phase 1 clinical study for A-005 being developed for neuroinflammatory and neurodegenerative diseases –

SOUTH SAN FRANCISCO, Calif., Nov. 13, 2024 (GLOBE NEWSWIRE) — Alumis Inc. (Nasdaq: ALMS), a clinical-stage biopharmaceutical company developing oral therapies using a precision approach to optimize clinical outcomes and significantly improve the lives of patients with immune-mediated diseases, today reported financial results for the third quarter ended September 30, 2024, and highlighted recent achievements and upcoming milestones.

“I am pleased with the important progress we’ve made across our three clinical programs, as the team continues to show operational focus and execution, leveraging this momentum towards important upcoming data readouts,” said Martin Babler, President and Chief Executive Officer of Alumis. “ESK-001 and A-005 are designed to be differentiated in the TYK2 space by achieving maximal TYK2 inhibition at doses with a favorable safety profile. With the potential to combine high biologic-like efficacy with oral convenience, we are well positioned to deliver on the promise and impact that TYK2 inhibition can have for patients with immune-mediated diseases.”

Babler continued, “We look forward to continuing to generate data with a goal of supporting best-in-class profiles for our programs, with A-005 Phase 1 data expected by year end and ESK-001 52-week Phase 2 OLE study data expected in the first quarter of 2025.”

Third Quarter 2024 Highlights

• Presented data at 2024 European Academy of Dermatology & Venereology (EADV) Congress supporting ESK-001’s potential to offer a differentiated and best-in-class treatment profile for people with moderate-to-severe plaque psoriasis:
  • Late-breaking 28-week data from the Open Label Extension (OLE) Phase 2 study show ESK-001 was generally well tolerated and most patients treated with the top dose of 40 mg twice daily achieved primary endpoint of PASI 75 (93% as observed (AO, n=71), 82.7% using modified non-responder imputation (mNRI, n=81)); Also, sPGA 0/1 responses of 76.1% (AO, n=71) and 67.9% (mNRI, n=81) were observed.
  • Additional data presented show that the 40 mg twice daily dose, which achieves maximal target inhibition according to blood and skin biopsy biomarkers, leads to the highest response rates. Importantly, positive efficacy and safety outcomes are associated with significant improvements in patients’ reported quality of life outcomes. These findings support use of the 40 mg twice daily dose in the ongoing Phase 3 clinical program.
• Continued to advance three clinical programs in immune-mediated diseases:
  • The Phase 3 ONWARD program for ESK-001 in moderate-to-severe plaque psoriasis consists of two parallel 24-week global Phase 3 clinical trials (ONWARD1 and ONWARD2) designed to evaluate the efficacy and safety of ESK-001 in adult patients with moderate-to-severe plaque psoriasis and also includes a long-term extension (LTE) trial, ONWARD3, designed to evaluate durability and maintenance of response and long-term safety. Topline results are anticipated in the first half of 2026.
  • The Phase 2b LUMUS program for ESK-001 in SLE is designed to evaluate the efficacy, safety and pharmacokinetics of multiple doses of ESK-001 in adult patients with moderately to severely active, autoantibody-positive SLE. Topline results are anticipated in 2026.
  • The Phase 1 clinical study of A-005, a potential first-in-class, central nervous system (CNS) penetrant TYK2 inhibitor being developed for the treatment of neuroinflammatory and neurodegenerative diseases, is designed to assess the safety, tolerability, and pharmacokinetics of single and multiple-ascending orally administered doses of A-005 in healthy participants, including confirmation of CNS penetration in humans. Data readout is anticipated by year-end 2024.

Anticipated Milestones

2024

• A-005: Phase 1 clinical study data in healthy participants (by year-end)

2025

• A-005: Initiation of Phase 2 clinical trial in multiple sclerosis (MS)
• ESK-001: Phase 2 OLE 52-week data update in psoriasis
• Third pipeline program: Investigational New Drug Application filing for third clinical candidate

2026

• ESK-001: Psoriasis Phase 3 topline data (1H 2026)
• ESK–001: SLE Phase 2b topline data
• A-005: MS Phase 2 topline data

Third Quarter 2024 Financial Results

• As of September 30, 2024, Alumis had cash and cash equivalents and marketable securities of $361.9 million, which is expected to fund operations into 2026.
• Research and development expenses were $87.8 million for the quarter ended September 30, 2024, compared to $37.8 million for the same period in 2023. The increase was driven by a clinical milestone payment of $23.0 million related to a prior acquisition of FronThera, an increase in contract manufacturing and clinical trial costs for the ESK-001 and A-005 programs, as well as increased headcount in research and development teams to support development efforts.
• General and administrative expenses were $10.6 million for the quarter ended September 30, 2024, compared to $6.0 million for the same period in 2023. The increase was primarily attributable to personnel-related expenses and professional consulting services to support the Company’s growth and business development.
• Net loss was $93.1 million for the quarter ended September 30, 2024, compared to $43.4 million for the same period in 2023.

Upcoming Events

• Alumis will be presenting two posters at ACR Convergence 2024, the annual meeting of the American College of Rheumatology (ACR) taking place November 14-19 in Washington, D.C.
