ANX1502 offers the convenience of an oral small molecule for complement-mediated autoimmune diseases, potentially disrupting a space dominated by infused biologics. The proof-of-concept study in cold agglutinin disease (CAD) is ongoing, with completion anticipated in 2026.
- ANX1502 is the first-in-kind oral small molecule inhibitor of C1s.
- Early data suggested the drug achieves targeted drug levels in fasted CAD patients.
Stopping neuroinflammation and tissue damage at the C1q source
The foundational value proposition across the pipeline is targeting C1q, the initiating molecule of the classical complement pathway, designed to stop the neuroinflammatory cascade before it causes tissue damage.
Annexon, Inc. reported cash and cash equivalents and short-term investments of $188.7 million as of September 30, 2025, extending its operating runway into late first quarter 2027. The Q3 2025 net loss was $54.9 million or $0.37 per share, with R&D expenses at $49.7 million for the quarter. The company also raised $86.25M in an underwritten public offering on November 14, 2025.
Annexon, Inc. (ANNX) - Canvas Business Model: Customer Relationships
You're looking at how Annexon, Inc. (ANNX) manages its key relationships with the specialized groups that drive its clinical and financial success as of late 2025. It's all about high-stakes engagement with investigators, regulators, patients, and the capital markets.
High-touch engagement with specialized clinical investigators and trial sites
The relationship with clinical sites is critical, especially for the ANX007 program. You need to know the scale of that commitment.
The Phase 3 ARCHER II trial for vonaprument (formerly ANX007) involved a significant global footprint:
| Metric | Value |
| Targeted Patient Enrollment (ARCHER II) | 630 patients |
| Number of Clinical Trial Locations (ARCHER II) | 117 locations |
| Enrollment Completion Date (Reported) | July 24, 2025 |
The relationship with investigators is built on the data package supporting tanruprubart (ANX005) for Guillain-Barré Syndrome (GBS), where 90% of treated patients showed functional improvement by Week 1 in the Phase 3 study.
Regulatory dialogue with the FDA and EMA for accelerated review pathways
The dialogue with regulators shapes the entire commercial timeline. For the lead GBS asset, the path involves distinct steps with the FDA and EMA.
- FDA Pre-BLA Meeting Timing (Anticipated)
- FDA BLA Submission Update Timing (Ongoing Discussions)
- EMA Marketing Authorization Application (MAA) Submission (Anticipated Q1 2026)
For ANX007, the relationship with the EMA resulted in the Product Development Coordinator (PDC) pilot selection in July 2025, supporting the path for potential first approval in both Europe and the U.S..
Patient advocacy and physician education via the open-label FORWARD study
The FORWARD study is a direct relationship-building tool, designed to educate the community on tanruprubart's single-infusion approach.
- FORWARD Study Initiation Quarter: Q2 2025

Annexon, Inc. (ANNX) - Canvas Business Model: Channels
You're looking at how Annexon, Inc. plans to get its novel C1q-targeted therapies to the specialists and patients who need them, especially as they move from late-stage trials toward potential first-in-class approvals. This is all about execution on the ground, which is where the rubber meets the road for any biotech.
The channel strategy heavily relies on direct interaction with regulatory bodies for approval, followed by a targeted, specialized outreach for commercialization, all while building credibility through data dissemination.
Direct regulatory submission pathways (BLA/MAA) to the FDA and EMA
Annexon, Inc. is channeling its lead GBS candidate, tanruprubart (ANX005), directly through the major regulatory gates. The company is preparing to submit a Marketing Authorization Application (MAA) to the EMA in the first quarter of 2026. For the FDA, the plan involves submitting a Biologics License Application (BLA) in 2026, following a forward-looking meeting with the agency in the second quarter of 2025.
For vonaprument (ANX007) in geographic atrophy (GA), the channel is a global registration path established with both the U.S. and Europe in mind, leveraging the data from the global Phase 3 ARCHER II program.
Here's a quick look at the near-term regulatory milestones that define this channel:
| Program | Indication | Key Regulatory Channel Event | Target Date/Status (Late 2025) |
| Tanruprubart (ANX005) | GBS | MAA Submission to EMA | Q1 2026 |
| Tanruprubart (ANX005) | GBS | BLA Submission to FDA | 2026 (Post Q2 2025 meeting) |
| Vonaprument (ANX007) | GA | Topline Phase 3 ARCHER II Data | H2 2026 |
| ANX1502 | CAD | Proof-of-Concept Update | Year-end 2025 |
Global network of specialized clinical trial sites (e.g., neurology, ophthalmology)
The clinical trial network is a critical channel for generating the evidence needed for regulatory submission and future adoption. Annexon, Inc. has been actively managing site engagement across its late-stage pipeline.
For the GA program, the Phase 3 ARCHER II trial successfully completed enrollment by the third quarter of 2025, surpassing its goal of 630 participants across its global sites. This trial is designed to support approval in both the U.S. and Europe.
The open-label FORWARD study for ANX005 in GBS is designed to broaden experience across sites in the United States, Canada, and Europe. Furthermore, the proof-of-concept trial for the oral candidate ANX1502 in cold agglutinin disease (CAD) involved dosing in up to seven patients.
Future specialized commercial sales force targeting rare disease centers and specialists
While regulatory filings are the immediate focus, Annexon, Inc. is clearly building the infrastructure for commercial launch, especially for GBS, a rare disease market estimated at $1.2 billion by 2030.
The company has already started building out the team needed to reach the right prescribers. You can see this in the move to strengthen the senior leadership team in key areas:
- Commercial
- Medical Affairs
- Health Economics
This focus on commercial and medical affairs leadership is a direct channel investment, preparing to target the specialists who treat GBS and GA, often concentrated in academic or specialized centers.
Scientific publications and medical conferences to disseminate data
Disseminating data through peer-reviewed channels and key medical meetings is the primary way Annexon, Inc. educates the medical community, which is a vital channel for driving future prescription volume. The company has been very active in 2025.

- Oral presentation of pivotal GBS data at the American Academy of Neurology (AAN) 2025 Annual Meeting (April 5-9, 2025) in San Diego, California.
- Presentation of Real-World Evidence (RWE) study data at the 2025 Peripheral Nerve Society (PNS) Annual Meeting (May 17-20, 2025) in Edinburgh, UK.
- Multiple posters and presentations scheduled for November 2025 at the AANEM meeting, covering ANX005 in GBS.
Financially, this educational push is supported by a strong balance sheet; as of Q2 2025, Annexon, Inc. reported $280 million in cash and equivalents, providing runway through the vonaprument topline data expected in H2 2026. That cash position helps fund the medical affairs and conference presence needed to prime the market.
Annexon, Inc. (ANNX) - Canvas Business Model: Customer Segments
You're looking at the core groups Annexon, Inc. (ANNX) is targeting with its complement-blocking platform, which is a pretty focused set of rare and chronic conditions. The numbers tell you exactly how big the potential patient pool is for each indication as of late 2025.
Patients with Guillain-Barré Syndrome (GBS), a rare, acute neurological disorder
This is the acute emergency segment for their lead program, tanruprubart. The global patient pool is small but critically underserved, which drives the urgency for their planned Marketing Authorization Application (MAA) submission expected in January 2026.
- Affects approximately 150,000 people worldwide each year.
- Global cases remain rare, around 1 in 100,000 annually.
- Incidence in cohort studies ranged from 0.30 to 6.08 cases per 100,000 people.
Patients with Geographic Atrophy (GA) secondary to dry Age-Related Macular Degeneration (AMD)
This is the chronic, high-prevalence ophthalmic segment where ANX007 is positioned as a potential vision-preserving therapy. The sheer number of people affected globally is substantial, even if the U.S. prevalence figures are based on Medicare Advantage data.
Here's a quick look at the scale of the GA patient population:
| Geographic Segment | Estimated Patient Count/Prevalence | Context/Source Year |
| Worldwide Patients | More than eight million | 2025 |
| United States Patients (at least 1 eye) | Approximately 1 million | 2025 |
| US Medicare Advantage Prevalence (Overall GA) | 0.51% | 2021 |
| Proportion of Legal Blindness from AMD | 20% | 2025 |
What this estimate hides is the exact number of patients eligible for a specific treatment regimen, but the total addressable market is definitely in the millions.
Patients with complement-mediated autoimmune diseases like Cold Agglutinin Disease (CAD)
ANX1502 targets this rare autoimmune space, which is characterized by low case numbers but high unmet need, especially for an oral option. The proof-of-concept trial completion was anticipated mid-2025, with an update expected later.
- U.S. prevalence is estimated up to 3 in 10,000 people living with the disease.
- 1-year prevalence across databases ranged from 1.4 to 3.1 per 100,000 persons.
- Primary CAD incidence is estimated between 0.6 to 1.2 per 100,000 persons annually.
- CAD accounts for up to 20% of Autoimmune Hemolytic Anemia (AIHA) cases.
Neurologists and Ophthalmologists specializing in complement-driven disorders
These are the prescribers and key opinion leaders. They are the ones who will adopt the novel mechanism of action, especially given the company's financial footing to support late-stage development. You want to keep these specialists focused on the data.
- Annexon, Inc. (ANNX) cash and investments as of September 30, 2025: $188.7 million.
- Projected operating runway extends into late first quarter 2027.
- Research and development expenses for Q3 2025 were $49.7 million.
Finance: draft 13-week cash view by Friday.
Annexon, Inc. (ANNX) - Canvas Business Model: Cost Structure
You're looking at the cost structure for Annexon, Inc. as of late 2025. For a late-stage biopharma like Annexon, Inc., the cost structure is overwhelmingly dominated by the pursuit of regulatory approval and pipeline advancement. The primary burn rate comes from research and development activities, which is where the money goes to fund those pivotal trials.
The dominant R&D expenses for the third quarter of 2025 totaled $49.7 million. This figure represents a significant year-over-year increase from the $30.1 million reported in Q3 2024, showing the ramp-up required for late-stage development. This spending is directly tied to the most critical near-term milestones.
The significant clinical trial costs are primarily embedded within that R&D spend. Specifically, the increased R&D expenses are associated with the advancement of the Phase 3 ARCHER II trial for vonaprument in Geographic Atrophy (GA) and the investments needed toward completion of tanruprubart global filings for Guillain-Barré Syndrome (GBS). Also, the ongoing proof-of-concept study for ANX1502 in Cold Agglutinin Disease (CAD) contributes to this outlay.
General and administrative (G&A) overhead covers the corporate infrastructure needed to manage these complex programs and prepare for potential commercialization. For the quarter ended September 30, 2025, G&A expenses were $7.3 million. Honestly, you can see management is focused on efficiency here, as this was a decline from the $9.3 million reported in Q3 2024, reflecting ongoing corporate efficiencies and disciplined prioritization of resources.
Manufacturing and supply chain development for future commercial production is a cost that is often intertwined with R&D until a product is approved and Cost of Goods Sold (COGS) becomes a line item. Annexon, Inc. has disclosed reliance on international third-party suppliers for its product candidates, which means these development and scale-up activities are subject to supply chain complexities and potential tariff impacts, though specific dollar amounts for this bucket aren't broken out separately from the main R&D spend.
Here's a quick look at the key expense components from the Q3 2025 period:
| Cost Component | Q3 2025 Amount (USD) | Q3 2024 Amount (USD) |
| Research and Development (R&D) Expenses | $49.7 million | $30.1 million |
| General and Administrative (G&A) Expenses | $7.3 million | $9.3 million |
| Implied Total Operating Expenses (R&D + G&A) | $57.0 million | $39.4 million |
| Net Loss for the Quarter | $54.9 million | $34.8 million |
The cash position at the end of the quarter supports this spending pace. Cash and cash equivalents and short-term investments were $188.7 million as of September 30, 2025. This financial position, based on focused investments, extends the expected runway to fund operations and anticipated milestones into late first quarter 2027.
The major cost drivers for Annexon, Inc. are:
- Advancement of the Phase 3 ARCHER II trial for vonaprument in GA.
- Investments toward completion of tanruprubart global filings for GBS.
- Ongoing clinical work for the ANX1502 proof-of-concept study in CAD.
- Corporate overhead supporting late-stage development and pre-commercial planning.

Annexon, Inc. (ANNX) - Canvas Business Model: Revenue Streams
You're looking at the revenue side of Annexon, Inc. (ANNX) as of late 2025. Since the company is still in the clinical-stage development phase, the immediate revenue picture is what you'd expect for a pre-commercial biotech.
Forecasted 2025 annual revenue is $0 as the company is pre-commercial. On average, 10 Wall Street analysts forecast ANNX's revenue for 2025 to be $0.
The primary source of cash inflow right now is non-operational, coming from capital markets activities. You saw this clearly with the recent equity raise. Annexon, Inc. announced the successful closing of its underwritten public offering on November 14, 2025, raising gross proceeds of approximately $86.25 million before deducting underwriting discounts and commissions. This capital infusion is crucial for funding the late-stage pipeline. To be fair, this offering was an upsized version of an initial proposed offering of $75 million, which included an underwriter option for up to an additional $11.25 million. As of September 30, 2025, the cash and operating runway was supported by $188.7 million in cash and cash equivalents, which the company expected to fund operations and anticipated milestones into the late first quarter 2027.
The real potential for product sales revenue hinges entirely on regulatory success for the pipeline candidates. These are the key value drivers you need to watch for future revenue generation.
Here's a look at the near-term catalysts that will shape the future product sales stream:
- Tanruprubart (ANX005) Marketing Authorisation Application (MAA) submission in Europe targeted for January 2026.
- Vonaprument (ANX007) topline data from the pivotal ARCHER II trial expected in the second half of 2026.
- ANX1502 Proof-of-Concept (POC) study completion anticipated by year-end 2025 or in 2026.
- The company is advancing its pipeline with focused investments, increasing Research and Development expenses to $49.7 million for the quarter ended September 30, 2025.
Milestone payments or upfront fees from future potential licensing deals represent another non-product revenue stream, though specific amounts aren't publically detailed right now. The company is advancing its next-generation complement inhibitors across multiple therapeutic areas, which creates partnership opportunities. For instance, vonaprument was selected by the European Medicines Agency (EMA) for the exclusive Product Development Coordinator (PDC) pilot in July 2025, which helps navigate regulatory interactions. This de-risking of the regulatory path for their lead assets definitely increases their attractiveness for potential future collaborations or out-licensing deals, which would bring in upfront cash or milestone payments.
You can map the current financial position and near-term value inflection points here:
| Revenue Stream Component | Metric/Amount | Date/Status (Late 2025) |
|---|---|---|
| Forecasted 2025 Product Revenue | $0 | Pre-commercial Status |
| Recent Equity Financing Proceeds | $86.25 million (Gross) | Closed November 14, 2025 |
| Cash Position | $188.7 million | As of September 30, 2025 |
| Projected Cash Runway | Into late first quarter 2027 | Based on focused investments |
| Tanruprubart Regulatory Milestone | MAA Submission | Targeted January 2026 |
| Vonaprument Pivotal Data Milestone | Topline ARCHER II Data | Targeted Second Half of 2026 |
