SOUTH SAN FRANCISCO, Calif., Aug. 16, 2021 (GLOBE NEWSWIRE) -- Annexon, Inc. (“Annexon”) (Nasdaq: ANNX), Annexon, a clinical-stage biopharmaceutical company developing a class of new complement medicines for patients with classical complement-mediated autoimmune and neurodegenerative disorders of the body, brain and eye, today announced second quarter 2021 financial results and provided a mid-year business update.
“We continue to make strong and consistent progress on our mission to deliver transformative therapies for patients suffering from classical complement-driven autoimmune and neurodegenerative diseases. With three clinical-stage drug candidates advancing in seven clinical trials, we remain laser-focused on developing game-changing therapies for patients in need while generating significant value for our shareholders,” said Douglas Love, Esq., president and chief executive officer of Annexon. “We also continue to expand our corporate capabilities and are pleased to announce the appointment of Will Waddill to our Board of Directors. Will has extensive experience in biotech and finance, and will provide an invaluable perspective as we enter our next phase of growth and value creation.”
Therapeutic Franchise Highlights and Updates
Annexon is advancing a portfolio of innovative C1 inhibitors to stop classical complement-mediated diseases at the start of the pathway in three therapeutic franchise areas: Autoimmune, Neurodegeneration and Ophthalmology.
Autoimmune Franchise
Annexon is pursuing a range of carefully selected neuromuscular, hematologic and nephritic antibody-mediated autoimmune indications where excess classical complement activity is a key driver of disease. During its July 28th C1q R&D series presentation, Annexon showcased the rationale and potential of its anti-C1 approach in autoimmune disease.
Recent highlights and updates in the Autoimmune franchise include:
- Progressed enrollment in the Phase 2/3 trial of ANX005 in Guillain-Barré Syndrome (GBS), which remains on track for completion in 2023. Data from the completed drug-drug interaction study and Phase 1b trial were recently presented at the 2021 Peripheral Nerve Society Annual Meeting, demonstrating tolerability and full C1q target engagement of ANX005 in combination with IVIg and reduction of cerebrospinal fluid (CSF) complement activity following ANX005 treatment in GBS patients.
- Advanced precision medicine approach to treat patients with a complement signature in the Phase 2 trial of ANX005 in warm autoimmune hemolytic anemia (wAIHA). In the ongoing Phase 0 (patient selection) component of the trial, several wAIHA patients have demonstrated a classical complement signature, making them potentially eligible for enrollment into the Phase 2 component of the trial. ANX005 was shown to fully inhibit complement activation of wAIHA antibodies in these patient sera. Data from the Phase 0 portion of the Phase 2 trial is expected to be submitted to a peer-reviewed forum in 2021.
- Strategic expansion of ANX005 into a Phase 2 program in Multifocal Motor Neuropathy (MMN), a neuromuscular disorder mechanistically related to GBS. Initiation of the Phase 2 study is anticipated in early 2022.
- Reported Phase 1 first-in-human (FIH) data for ANX009 subcutaneous product candidate, Annexon’s third clinical stage drug candidate, which is being developed for the treatment of antibody-mediated autoimmune diseases of blood and vascular tissues. ANX009 was shown to be well tolerated with complete and sustained C1q inhibition, supporting twice weekly subcutaneous administration. Data from the FIH study is expected to be submitted to a peer-reviewed forum in 2021.
- Advanced ANX009 into a Phase 1b study in Lupus Nephritis (LN), a nephritic disease characterized by autoantibody-driven activation of C1q and the classical complement pathway. Endogenous pathogenic anti-C1q antibodies (PACAs) have been shown to correlate with classical complement activation and disease activity. Initiation of the Phase 1b study is anticipated in early 2022 and will deploy Annexon’s precision medicine approach targeting patients with excess classical complement and PACA activity. Complement and PACA data in LN patient samples is expected to be submitted to a peer-reviewed forum in 2021.
Neurodegeneration Franchise
Annexon is pioneering an approach to stop complement-mediated neurodegeneration at the start, leveraging its original discoveries of the role of C1q as a major driver of synaptic loss and neurodegeneration. Blocking C1q potentially protects against functioning synapse loss and may provide functional benefit. Annexon is utilizing biomarkers of neuronal damage to measure impact on disease.
Recent highlights and updates in the Neurodegeneration franchise include:
- Completed enrollment in Phase 2 trial of ANX005 in Huntington’s Disease (HD) and expects to report initial data in Q4 2021.
- Initiated patient dosing in Phase 2 trial of ANX005 in Amyotrophic Lateral Sclerosis (ALS) and now expects to report data in 2022 due to slower initial enrollment.
- Completed preclinical study of ANX005 in SOD1 model of ALS, which demonstrated preserved neuromuscular function and reduced neuronal damage as measured by Neurofilament Light Chain (NfL). Data from the SOD1 preclinical study represent the third instance of NfL reduction by ANX005, following the Phase 1b trial in GBS patients and R6/2 preclinical model of HD. Results from the ALS preclinical study are expected to be submitted to a peer-reviewed forum in 2021.
Ophthalmology Franchise
Annexon is utilizing intravitreal administration of ANX007 to inhibit C1q, which is implicated in neurodegeneration in the retina. Selectively targeting C1q at the start of the classical pathway versus downstream approaches may enhance efficacy and safety for patients in ophthalmic disorders, including Geographic Atrophy (GA).
Recent highlights and updates in the Ophthalmology franchise include:
- Progressed enrollment in the Phase 2 trial of ANX007 in GA, which remains on track for completion in 2023.
- ANX007 data demonstrating full target engagement of C1q in the outer layers of the retina in preclinical models is expected to be submitted to a peer-reviewed forum in 2021.
Corporate Update
- In August 2021, Annexon appointed Will Waddill to its Board of Directors. Mr. Waddill brings decades of financial and operational expertise in the biotechnology industry and a distinguished track record of leadership in industry organizations, including the Association of Bioscience Financial Officers (ABFO) and the Biotechnology Industry Organization (BIO). Mr. Waddill currently serves on the boards of Protagonist Therapeutics and Arrowhead Pharmaceuticals. Most recently, he served as Senior Vice President, CFO, of Calithera Bioscience from 2014 to 2016 and previously held senior finance leadership roles at OncoMed Pharmaceuticals and Ilypsa.
