$271 Million Cash and Investments at End of Third Quarter 2021 Supports Operating Runway into 2024, Including Several Key Clinical Milestones across the Portfolio

SOUTH SAN FRANCISCO, Calif., Nov. 09, 2021 (GLOBE NEWSWIRE) -- Annexon, Inc. (Nasdaq: ANNX), a clinical-stage biopharmaceutical company developing a new class of complement medicines for patients with classical complement-mediated autoimmune, neurodegenerative and ophthalmic disorders, today announced recent highlights and reported third quarter 2021 financial results.

“The third quarter marks another quarter of meaningful progress with our portfolio, including effectively advancing three clinical-stage product candidates in five clinical trials,” said Douglas Love, Esq., president and chief executive officer of Annexon. “We’re also pleased to have been granted Orphan Drug designation by the FDA for ANX005, underscoring the Agency’s recognition of ANX005’s potential as a novel therapy for the treatment of Huntington’s disease. Additionally, in collaboration with multiple academic and physician key opinion leaders, we conducted two C1q Series R&D Events that highlighted the applicability of our platform and differentiated scientific approach targeting the classical complement cascade in a range of autoimmune and neurodegenerative diseases. The combination of a rich set of milestones, a strong balance sheet, and a talented team, lays the foundation for a transformational year ahead. We look forward to sharing the continued progress across our portfolio, including initial data from our Huntington’s disease clinical trial, as we work to bring treatments to patients suffering from serious complement-mediated diseases.”

Program Highlights

  • Second C1q Series R&D Event Highlights Neurodegeneration Franchise: Annexon hosted its second C1q Series event, which spotlighted the company’s neurodegeneration franchise and approach to treating complement-mediated neurodegenerative diseases. During the event, Annexon’s leadership team and participating key opinion leaders shared their perspectives on:
    • The role of C1q and the classical complement pathway in neurodegenerative diseases, including Huntington’s disease (HD) and amyotrophic lateral sclerosis (ALS);
    • Research on neurofilament light chain (NfL) and natural history data showing the association of a rise in NfL with clinical progression in both HD and ALS; and
    • Internal data demonstrating the ability to reduce NfL with ANX005, both clinically in Guillain-Barré syndrome (GBS), and preclinically in HD and ALS.
  • Initial Data from Phase 2 trial of ANX005 in HD Expected in the Fourth Quarter of 2021: Annexon is studying its lead compound, ANX005, a clinical-stage investigational monoclonal antibody intended to treat patients with complement-mediated disorders, in a Phase 2 trial in patients with HD. The company anticipates initial data from the trial in the fourth quarter of 2021, which is expected to include data from a subset of 16 patients who have completed the six-month treatment period, including safety and tolerability, C1q target engagement in cerebral spinal fluid and serum, and impact on NfL levels. The full dataset from all patients who complete both the six-month on-treatment and three-month off-treatment periods are expected to be reported in the first half of 2022.
  • ANX005 Granted Orphan Drug Designation for the Treatment of HD: The U.S. Food and Drug Administration (FDA) has granted Orphan Drug designation for ANX005 for the treatment of patients with HD. Orphan Drug designation provides orphan status to drugs or biologics that are intended to treat rare diseases or disorders affecting fewer than 200,000 people in the United States, and certain incentives to the product sponsor, including tax credits for qualified clinical trials and fee waivers. The designation confers eligibility for seven years of market exclusivity following FDA product approval.

Business Highlights

  • Leadership Team Strengthened by Appointment of Ted Yednock, Ph.D., as Chief Innovation Officer and Larry Mattheakis, Ph.D., as Chief Scientific Officer: In the third quarter, Annexon appointed Ted Yednock, Ph.D., as chief innovation officer (CIO), and Larry Mattheakis, Ph.D., as chief scientific officer (CSO). Dr. Ted Yednock served as Annexon’s CSO since 2013. As CIO, he will serve as chairman of the Scientific Advisory Board and continue to enhance and integrate Annexon’s key scientific findings and collaborations. Dr. Larry Mattheakis brings decades of drug discovery and development expertise to the CSO role, supporting the advancement of Annexon’s current and future pipeline.

Third Quarter 2021 Financial Results

  • Cash and Operating Runway: Cash and cash equivalents and short-term investments were $271.4 million as of September 30, 2021. Annexon expects that its current cash position is sufficient to fund its operating plans into 2024.
  • Research and development (R&D) expenses: R&D expenses were $27.6 million for the quarter ended September 30, 2021, compared to $11.8 million for the quarter ended September 30, 2020.
  • General and administrative (G&A) expenses: G&A expenses were $8.1 million for the quarter ended September 30, 2021, compared to $3.8 million for the quarter ended September 30, 2020.
  • Net loss: Net loss was $35.6 million or $0.93 per share for the quarter ended September 30, 2021, compared to $15.6 million or $0.77 per share for the quarter ended September 30, 2020.
