LOS ANGELES, Nov. 13, 2024 (GLOBE NEWSWIRE) -- ACELYRIN, INC. (Nasdaq: SLRN), a late-stage clinical biopharma company focused on accelerating the development and delivery of transformative medicines in immunology, today reported financial results for the third quarter ended September 30, 2024 and highlighted other corporate updates and milestones.
“We are executing on our refocused pipeline strategy and are excited by the near-term catalysts ahead for ACELYRIN, particularly as we advance subcutaneous lonigutamab into Phase 3 development as the next generation IGF-1R inhibitor for thyroid eye disease. We recently concluded a positive end of phase 2 interaction with the FDA, established a world-class scientific and patient advisory board, and remain on track to initiate our Phase 3 development program in TED next quarter,” said Mina Kim, Chief Executive Officer of ACELYRIN. “We are also looking forward to announcing topline results from our Phase 2b/3 trial of izokibep in uveitis in December 2024 and hosting a lonigutamab investor event in early 2025.”
Recent Pipeline Updates and Upcoming Milestones
Lonigutamab
Lonigutamab is a subcutaneously (SC) delivered humanized IgG1 monoclonal antibody targeting the insulin-like growth factor-1 receptor (IGF-1R), a validated mechanism of action (MoA) for the treatment for thyroid eye disease (TED).
- ACELYRIN recently completed a positive end of Phase 2 (EOP2) interaction with the U.S. Food and Drug Administration (FDA), achieving alignment on important elements of the Phase 3 registrational program design including size, primary and secondary endpoints, and proposed dose selection. The Company will host a webcast event in early 2025 to review the Phase 2 data, FDA feedback and Phase 3 program design.
- Earlier this year, ACELYRIN reported the first positive proof of concept data for an anti-IGF-1R in TED patients, which showed that lonigutamab was well-tolerated and demonstrated rapid improvements in proptosis and clinical activity score (CAS) – within three weeks after the first dose. Additional data from the ongoing Phase 2 trial has been recently presented by leading clinicians at international medical congresses including those of the American Society of Ophthalmic Plastic and Reconstructive Surgery, the European Society of Ophthalmic Plastic and Reconstructive Surgery, and the American Academy of Ophthalmology. These presentations can be found on the “Presentations and Publications” section of ACELYRIN’s website at www.acelyrin.com.
- The Phase 2 dose exploration trial is continuing with additional cohorts to establish both a minimum effective and optimal dose level and dose regimen for the Phase 3 registrational program. Cohort 3 testing 50mg of lonigutamab administered every four weeks has been completed and Cohort 4 testing 70-100mg of lonigutamab administered every four weeks is ongoing.
- Finally, ACELYRIN established a scientific and patient advisory board convening world class clinicians and advocates to provide important strategic input, clinical expertise and patient perspectives as the Company prepares to advance lonigutamab into Phase 3 clinical development for TED.
Izokibep
Izokibep is a small protein therapeutic designed to inhibit IL-17A with high potency and small molecular size, approximately 1/10th the size of a monoclonal antibody.
ACELYRIN previously announced that enrollment in a Phase 2b/3 trial evaluating 160mg of izokibep administered weekly as a treatment for non-infectious, non-interior uveitis had been completed in May 2024 with 96 patients. The Company expects to report topline data from the trial in December 2024.
Third Quarter 2024 Financial Highlights
Cash Position: Cash, cash equivalents and short-term marketable securities totaled $562.4 million at September 30, 2024. The Company expects these to fund operations to mid-2027.
R&D Expenses: Research and development expenses were $31.6 million for the third quarter ended September 30, 2024, as compared to $74.6 million for the same period in 2023. The decreases were primarily a result of reduced clinical development activity as the Phase 3 trials for izokibep move toward completion.
G&A Expenses: For the third quarter ended September 30, 2024, general and administrative expenses were $12.3 million, compared to $19.9 million for the same period in 2023. The decreases were primarily a result of lower stock-based compensation expenses.
Net Loss: Net loss for the third quarter ended September 30, 2024 totaled $48.5 million, compared to $83.9 million for the same period in 2023. The net loss for the third quarter ended September 30, 2024 includes non-recurring restructuring expenses of $10.8 million related to the August 2024 announcement of a refocused pipeline strategy that prioritizes development of lonigutamab in thyroid eye disease. These restructuring expenses are net of a $35.7 million credit voucher that can be used to offset cash obligations for manufacturing costs including those for the lonigutamab program.
