ANNX fell 5.78% while key peers showed mixed performance: NMRA (-3.03%), ALEC (-1.58%), LCTX (-2.92%), MNPR (-6.08%), and OMER (+1.30%). Momentum scanner flagged OMER and NMRA moving up, underscoring stock‑specific weakness in ANNX rather than a clean sector‑wide move.
Historical Context
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Jan 16 | Inducement grants | Neutral | +1.5% | Equity awards to new employees under inducement plan. |
| Jan 12 | Pipeline milestones | Positive | +5.9% | Outlined 2026 priorities and multiple registrational milestones, including vonaprument. |
| Jan 08 | Regulatory filing | Positive | -4.3% | Submitted MAA to EMA for tanruprubart in Guillain‑Barré syndrome. |
| Jan 07 | Conference appearance | Neutral | +8.4% | Announced presentation at the 44th Annual J.P. Morgan Healthcare Conference. |
| Dec 16 | Inducement grant | Neutral | +2.1% | Option grant to a new non‑executive employee under inducement plan. |
Recent news has often been met with positive or mixed price reactions, with one notable selloff on a positive regulatory milestone.
Over the last few months, Annexon has reported multiple corporate and pipeline milestones. In January 2026, it detailed 2026 registrational priorities, including vonaprument Phase 3 ARCHER II topline data expected in H2 2026, which saw a +5.9% move. A European MAA submission for tanruprubart on Jan 8, 2026 led to a -4.34% reaction, showing that positive regulatory steps have not always translated into gains. Routine items like inducement grants and conference presentations have generally coincided with modestly positive trading. Today’s KOL event announcement fits the pattern of non‑clinical updates around the GA program.
Market Pulse Summary
This announcement highlights Annexon’s effort to spotlight vonaprument and the pivotal Phase 3 ARCHER II program in geographic atrophy through an in‑person and virtual KOL event on March 18, 2026. Recent history includes key regulatory steps for tanruprubart and a 2026 milestones update. Investors may watch for new clinical insights on vonaprument, clarity on the ARCHER II readout timing in H2 2026, and how upcoming data and financing disclosures shape the company’s late‑stage strategy.

About Eleonora Lad, MD, PhD
Eleonora Lad, MD, PhD is a clinician scientist and retinal ophthalmologist with the primary goal of developing novel strategies for early diagnosis and treatment of AMD. Dr. Lad specializes in the diagnosis and treatment of macular diseases, such as AMD, diabetic retinopathy, and retinal vascular diseases. She is involved in clinical trials and innovative therapies for the treatment of macular diseases. Dr. Lad is committed to providing the highest level of evidence-based patient care. Dr. Lad’s career goal is to translate her doctoral training in neuroscience into developing innovative diagnostic and therapeutic approaches for AMD. Her research interests are the following: 1) investigating the role of neuroinflammation and abnormal protein aggregates in the pathogenesis of AMD and developing relevant treatments, 2) visual function testing in dry AMD with the goal of establishing functional endpoints for future clinical studies in early AMD, 3) elucidating the use of novel retinal imaging biomarkers for early diagnosis of aging diseases (AMD and Alzheimer’s disease), including through the use of artificial intelligence (machine and deep learning). On these studies, she is collaborating with an interdisciplinary team of investigators from Ophthalmology, Geriatrics, Computer Engineering, Biomedical Engineering, Neurology and Alzheimer’s Disease Research Center.

About Vonaprument (formerly ANX007)
Vonaprument is a clinical-stage investigational antigen-binding fragment (Fab) designed as a first-in-kind therapeutic to selectively inhibit C1q, the initiating molecule of the classical complement pathway and a key driver of neurodegeneration. It is formulated for intravitreal (IVT) administration, with the potential to be the first targeted vision-preserving therapy for GA. Vonaprument involves a differentiated neuroprotective approach designed to protect photoreceptor cells and retinal function by blocking C1q and the entire classical pathway, while allowing for normal immune activity of the lectin and alternative complement pathways. Vonaprument has been granted Fast Track designation from the U.S. Food and Drug Administration (FDA) and is the first therapeutic candidate for the treatment of GA to receive Priority Medicine (PRIME) designation from the European Medicines Agency for the treatment of GA.
About the Phase 3 ARCHER II Trial
ARCHER II is a global, randomized, double-masked, sham-controlled Phase 3 trial that has enrolled more than 630 patients with advanced dry AMD with GA. Patients will be randomized 2:1 to receive a monthly dose of vonaprument or sham procedure. The primary endpoint is the prevention of ≥15-letter loss of best corrected visual acuity (BCVA), which represents three lines on the standard Early Treatment of Diabetic Retinopathy Study (ETDRS) eye chart. The primary analysis will occur at least 12 months from dosing. Proportion of patients experiencing BCVA ≥15-letter loss is a well-established functional endpoint that has served as the basis for numerous ophthalmology drug approvals by the FDA and European Medicines Agency. Secondary endpoints in ARCHER II include safety, low-luminance visual acuity (LLVA), and photoreceptor integrity (EZ). Topline data are expected in the second half of 2026.
About Annexon
