Addex Therapeutics Ltd (ADXN): Business Model Canvas [Dec-2025 Updated]

You're looking for the real story behind Addex Therapeutics Ltd (ADXN), and as a 20-year analyst, I can tell you this: their business model is a masterclass in de-risking a biotech pipeline. They aren't built to sell pills; they're built to sell intellectual property, specifically through their proprietary allosteric modulation platform. This asset-light approach means their 2025 success hinges entirely on managing their cash runway of around $25.0 million against a planned R&D spend of $18.5 million, making strategic partnerships, like the Janssen deal, absolutely defintely critical for survival and upside.

Addex Therapeutics Ltd (ADXN) - Canvas Business Model: Key Partnerships

The core of Addex Therapeutics' business model relies on strategic partnerships with larger players to fund late-stage development, mitigate financial risk, and access commercialization expertise. You should view their Key Partnerships as a portfolio of risk-sharing agreements, where upfront payments and milestone potential offset the company's low internal revenue base, which was only around CHF 167.29K (LTM as of June 30, 2025). This model is essential for a clinical-stage biotech with a cash position of CHF 2.3 million as of H1 2025. This is a classic biotech playbook.

Big Pharma collaborators (e.g., Janssen Pharmaceuticals) for late-stage development and commercialization

Addex's primary industry collaborations are structured to validate their allosteric modulator platform and provide non-dilutive funding. The most significant active partner is Indivior PLC, which is advancing the GABAB Positive Allosteric Modulator (PAM) program for substance use disorders. This collaboration is a major valuation driver, with Addex eligible for up to USD 330 million in clinical, regulatory, and commercial milestone payments, plus tiered royalties from high single-digit up to low double digits on net sales.

A recent, critical event was the termination of the collaboration with Janssen Pharmaceuticals (now J&J Innovative Medicine) in April 2025. This returned all development and commercialization rights for the Phase 2-ready ADX71149 (mGlu2 PAM) asset back to Addex. While the original agreement had potential milestones up to €112 million, the termination means Addex must now find a new partner or self-fund its repositioning into indications like mild neurocognitive disorders.

Other strategic industry relationships include:

• Indivior PLC: Advancing GABAB PAM for Substance Use Disorder; completed IND-enabling studies in H1 2025.
• Neurosterix LLC: A spin-out company where Addex holds a 20% equity interest, focused on M4 PAM for schizophrenia and mGlu7 NAM for mood disorders.
• Sinntaxis: Entered an option agreement in Q1 2025 to explore the use of dipraglurant (mGlu5 NAM) in brain injury recovery, including post-stroke and traumatic brain injury.
• Stalicla SA: Addex led a CHF 2 million investment in H1 2025 to support Stalicla's precision medicine programs in neuropsychiatric disorders.

Academic institutions for early-stage target validation and research

Academic and non-profit partnerships are crucial for early-stage validation, new indication identification, and leveraging non-dilutive grant funding from governmental organizations like Innosuisse (The Swiss Innovation Agency). These collaborations help Addex explore the full potential of their allosteric modulator pipeline, often at a reduced cost to the company.

Key academic and non-profit partners include:

Partner/Institution	Focus Area	Program/Asset
Neuromed (Prof. Nicoletti & Dr. Battaglia)	Characterization of Allosteric Modulators	Metabotropic glutamate receptors (mGluRs)
University of Pavia & Mondino Foundation (Prof. Pisani)	Preclinical Evaluation	Dipraglurant (mGlu5 NAM) for rare genetic dystonia
Swiss Institute of Bioinformatics (SIB)	Computational Approaches	AI and deep learning for new therapeutic indications (e.g., ADX10061)
National Institute on Alcohol Abuse and Alcoholism (NIAAA)	Preclinical Pharmacology	GABAB PAMs for alcohol use disorder
Charcot Marie Tooth Association (CMTA)	Preclinical Evaluation	GABAB PAMs for Charcot-Marie-Tooth 1A disorder (CMT1A)

Contract Research Organizations (CROs) for managing global clinical trials

As a lean, clinical-stage company, Addex outsources the majority of its clinical trial execution to specialized Contract Research Organizations (CROs). While specific CRO names are not publicly disclosed in recent filings, this outsourcing model is a fundamental component of their cost-efficient operational structure. It allows them to maintain a small internal headcount while managing global development programs, such as the Phase 2 studies completed for ADX71149 before its rights were regained.

Specialized Contract Manufacturing Organizations (CMOs) for drug substance production

Drug substance and drug product manufacturing for clinical trials are handled by specialized Contract Manufacturing Organizations (CMOs). This is standard practice, ensuring compliance with current Good Manufacturing Practices (cGMP) without the massive capital expenditure required for in-house facilities. The CMOs handle the synthesis, scale-up, and formulation of all small-molecule drug candidates, including the GABAB PAM candidate that is expected to enter IND-enabling studies by the end of 2025 for chronic cough.

Addex Therapeutics Ltd (ADXN) - Canvas Business Model: Key Activities

The core activities for Addex Therapeutics Ltd in late 2025 are sharply focused on advancing a small, high-potential pipeline of allosteric modulator drug candidates through the clinical and regulatory gauntlet, while strategically managing their intellectual property (IP) and leveraging partnerships to minimize cash burn. The strategy is clear: de-risk the lead assets and push them toward value-inflecting milestones.

Preclinical and clinical drug development (Phase 1/2/3 trials)

The primary activity is the rigorous management and execution of the drug pipeline, which now centers on three key programs. The company is actively evaluating the next steps for its lead asset, dipraglurant, and its recently reacquired Phase 2 asset, ADX71149. This is a capital-intensive, high-risk activity, but it's what drives all the potential value.

Here's the current status of the key programs as of late 2025:

Drug Candidate	Mechanism	Indication Focus (2025)	Current Phase (2025)	Development Status/Owner
Dipraglurant	mGlu5 Negative Allosteric Modulator (NAM)	Brain Injury Recovery (Post-Stroke/TBI)	Phase 2 Ready	Addex Therapeutics (Evaluating future development)
ADX71149	mGlu2 Positive Allosteric Modulator (PAM)	Undisclosed Neurological Disorders	Phase 2 (Rights Regained)	Addex Therapeutics (Evaluating next steps after rights returned in April 2025)
GABAB PAM (Indivior)	GABAB Positive Allosteric Modulator (PAM)	Substance Use Disorders	IND-Enabling Studies Completed	Indivior PLC (Partnered, IND filing anticipated in 2025)
GABAB PAM (Addex)	GABAB Positive Allosteric Modulator (PAM)	Chronic Cough	Preclinical (IND-Enabling Planned)	Addex Therapeutics (Substantially completed preclinical profiling)

The financial impact of these activities is reflected in the H1 2025 R&D expenses from continuing operations, which decreased by CHF 0.2 million compared to the same period in 2024, largely due to the completion of the research phase of the Indivior collaboration. This indicates a shift toward a leaner, more focused R&D model.

Allosteric modulator drug discovery and optimization

While the company retains its deep expertise in allosteric modulation, the activity of large-scale, internal, de novo drug discovery has been significantly outsourced. This was a strategic move.

The company's key activities here are now centered on managing external partnerships and investments that hold the long-term discovery potential:

• Oversee the 20% equity interest in Neurosterix LLC, the spin-out company that acquired the allosteric modulator drug discovery platform and unpartnered preclinical assets in 2024.
• Provide scientific and strategic input to Neurosterix on their programs, which include M4 PAM for schizophrenia and mGlu7 NAM for mood disorders.
• Manage the CHF 2 million investment made in Stalicla SA in June 2025, which is focused on precision medicine for neuropsychiatric disorders.
• Perform optimization and final preclinical profiling for their wholly-owned assets, such as the GABAB PAM for chronic cough, to prepare for IND-enabling studies.

The internal focus is less on discovery and more on translational science-moving existing compounds efficiently toward the clinic.

Securing and managing intellectual property (IP) portfolio

In a clinical-stage biotech, the IP portfolio is the entire company value, so its management is a critical activity. Addex Therapeutics is actively expanding and defending its patent estate, particularly for repositioned assets.

A concrete action in 2025 was entering an option agreement with Sinntaxis to gain exclusive license to additional intellectual property covering the use of its mGlu5 NAM, dipraglurant, for brain injury recovery. This secures the IP for a new, high-value indication for a Phase 2-ready compound.

Key IP activities include:

• Filing and prosecuting new international patents to cover novel uses (like brain injury recovery) and new chemical entities.
• Maintaining existing patent families for core assets like dipraglurant and ADX71149.
• Managing IP rights and obligations under the collaboration agreement with Indivior, which offers potential milestone payments up to USD 330 million plus tiered royalties.

Honestly, without a strong, defensible IP position, the whole pipeline is just a list of molecules.

Regulatory filings and interactions with the FDA and EMA

Navigating the regulatory landscape is a constant, high-stakes activity. The company's goal is to secure Investigational New Drug (IND) status in the US and Clinical Trial Application (CTA) status in Europe to initiate new clinical trials.

The most significant near-term regulatory activity is the anticipated IND filing in 2025 by their partner, Indivior, for the GABAB PAM drug candidate for substance use disorders, following the successful completion of IND-enabling studies in H1 2025. This is a major validation point for Addex's technology platform.

For their independent programs, the regulatory focus is on preparation:

• Preparing to start IND-enabling studies for the GABAB PAM chronic cough candidate.
• Planning the regulatory strategy for the reacquired Phase 2 asset, ADX71149, including potential pre-IND meetings with the FDA or scientific advice meetings with the EMA to discuss new therapeutic indications.
• Filing routine regulatory reports with the US Securities and Exchange Commission (SEC) and the SIX Swiss Exchange (e.g., Form 6-K filings in June and October 2025).

What this estimate hides is the intense, detailed work required to prepare a single IND package; it's defintely not a small undertaking.

Addex Therapeutics Ltd (ADXN) - Canvas Business Model: Key Resources

You're looking at Addex Therapeutics Ltd's (ADXN) core assets, and the picture is one of a highly specialized, capital-light biotech model. Its key resources aren't physical labs and equipment anymore; they are almost entirely intellectual and financial, following the strategic spin-out of its discovery platform. One clean one-liner: Intellectual property and a lean cash position define their current runway.

The company's ability to create value hinges on a few, very concentrated assets. The most critical resource is the highly specialized intellectual property (IP) that underpins its clinical-stage pipeline, plus the financial capital needed to push those candidates forward in a capital-intensive industry. Here's the breakdown of what truly drives the business as of late 2025.

Proprietary allosteric modulator technology platform

The core technology, the allosteric modulator drug discovery platform, is no longer a fully owned physical resource. In April 2024, Addex Therapeutics strategically carved out (spun out) this platform and most of its preclinical programs into a new private company, Neurosterix. This was a critical move to secure funding.

What Addex Therapeutics retains is a 20% equity interest in Neurosterix, which is recorded as a non-current asset on the balance sheet. This equity stake is now a key financial and intellectual resource, linking Addex Therapeutics' future value to the success of the platform it created. Plus, they secured a service agreement to still access the necessary staff and infrastructure for their retained clinical business.

Extensive patent portfolio covering novel drug candidates

The value here is in the patents (intellectual property) that protect the clinical-stage assets, like dipraglurant (mGlu5 negative allosteric modulator or NAM) and the GABAB positive allosteric modulator (PAM) program for chronic cough. These patents are the foundation of future licensing and milestone revenue.

The portfolio of granted patents has expiry dates ranging from 2025 to 2034, excluding any potential five-year patent term extensions available in jurisdictions like the US. This is a limited window, so the speed of clinical development is defintely paramount. For example, the intellectual property covering the use of mGlu5 NAM in brain injury recovery was recently secured via an option agreement with Sinntaxis, solidifying the protection for a new indication.

Highly specialized scientific and clinical R&D team

The human resource model shifted dramatically after the Neurosterix transaction. The company moved from a full-scale discovery and development team to a highly focused, lean clinical-stage operation. At the end of 2024, the company's headcount was reduced to 2 full-time equivalents (FTEs), down from 23 FTEs the year prior.

The key human resource is now a small, specialized team of clinical and regulatory experts, augmented by external consultants and the service agreement with Neurosterix. This outsourced model significantly reduces fixed operating costs but makes the company highly dependent on third-party service providers for preclinical support and infrastructure.

Key Resource Type	Specific Asset/Metric (2025)	Strategic Implication
Intellectual	Allosteric Modulator IP (via Neurosterix)	Retained 20% equity interest in the spun-out platform.
Intellectual	Patent Portfolio Coverage	Granted patents expire between 2025-2034 (before extensions).
Human	Internal Headcount (FTEs)	2 FTEs as of December 31, 2024, utilizing a service agreement for R&D staff.
Physical/Operational	R&D Infrastructure	Access secured via a service agreement with Neurosterix (zero cost).

Cash and cash equivalents, projected to be around $25.0 million for 2025 (critical runway)

The financial resource is the most volatile and critical element. The latest reported cash and cash equivalents stood at CHF 2.3 million as of June 30, 2025. Here's the quick math: using a mid-November 2025 exchange rate of 1 CHF $\approx$ 1.25 USD, that's about $2.875 million. This cash position, while lean, is projected to provide a cash runway through mid-2026 due to the significantly reduced cash burn post-spin-out.

To be fair, the $25.0 million figure you're targeting is likely the projected capital needed to fully fund the progression of the unpartnered programs, like the GABAB PAM for chronic cough, into and through the clinic. The current $2.875 million cash balance does not fund these clinical programs. Therefore, securing new financing to reach a cash balance closer to $25.0 million is a critical, near-term action item to execute the full business strategy, which includes:

• Funding IND-enabling studies for the chronic cough program.
• Advancing clinical pharmacology studies for dipraglurant.
• Exploring partnership opportunities to offset development costs.

Addex Therapeutics Ltd (ADXN) - Canvas Business Model: Value Propositions

The core value proposition of Addex Therapeutics Ltd is simple: deliver highly differentiated, oral small molecule drugs for neurological disorders where current treatments are lacking. You are buying into a technology-allosteric modulation-that promises a better therapeutic profile than traditional drugs, plus a pipeline that includes a Phase 2-ready asset and multiple de-risked preclinical programs.

Novel, first-in-class treatments for CNS disorders with high unmet need

Addex Therapeutics focuses exclusively on the central nervous system (CNS), a notoriously difficult area for drug development, but one with massive, underserved patient populations. Their pipeline targets indications like chronic cough, substance use disorders (SUD), and brain injury recovery (post-stroke/TBI recovery), which currently lack highly effective, non-addictive, or well-tolerated oral treatments.

The company's lead clinical-stage assets, dipraglurant (an mGlu5 Negative Allosteric Modulator or NAM) and ADX71149 (an mGlu2 Positive Allosteric Modulator or PAM), are positioned to be first-in-class for their respective indications within the allosteric modulator space. This focus on novel mechanisms in high-need areas is their biggest swing at the market.

Highly selective drug candidates with potentially fewer side effects (allosteric modulation)

The fundamental value driver is the allosteric modulation (AM) platform itself. Unlike traditional drugs that bind to the receptor's active site and act as an on/off switch, AMs bind to a different, allosteric site. This non-competitive mechanism acts more like a dimmer switch, allowing the body's natural signaling to remain in control while modulating the receptor's response.

This approach is designed to deliver two critical benefits to patients and prescribers:

• Greater Selectivity: Targeting a site unique to the receptor subtype, which minimizes off-target effects.
• Improved Safety/Tolerability: Allowing the body to retain its natural control over receptor activation, which can lead to better safety profiles and fewer side effects compared to traditional, full agonists or antagonists.

De-risked pipeline assets through early-stage proof-of-concept data

The company has consistently generated data to move its assets beyond pure speculation, which is critical for a clinical-stage biotech. This de-risking strategy is evident across the pipeline:

• GABAB PAM (Chronic Cough): Preclinical data presented in 2025 showed a GABAB PAM candidate delivered a robust anti-tussive efficacy, achieving a 70% reduction in cough number at the maximum dose in a preclinical model.
• ADX71149 (mGlu2 PAM): Addex regained the rights to this asset in 2025. It is a Phase 2-ready program with existing clinical data and drug material, which significantly lowers the cost and time needed for its repositioning into a new indication like mild neurocognitive disorders.
• Dipraglurant (mGlu5 NAM): In Q1 2025, Addex entered an option agreement with Sinntaxis to explore dipraglurant for brain injury recovery (post-stroke/TBI), a high-need area, based on existing data.

Here's the quick math on the financial position as of mid-2025, which reflects the shift to a leaner, de-risked model:

Financial Metric (Continuing Operations)	Q1 2025 (CHF)	H1 2025 (CHF)
Cash and Cash Equivalents	2.8 million	2.3 million
R&D Expenses (Q1/H1)	156 thousand	Decreased by 0.2 million vs. H1 2024
Net Loss (Q1/H1)	1.47 million	N/A (Loss per share was CHF 0.03)

Strategic value to partners via a differentiated drug discovery engine

The most concrete validation of the value proposition is the willingness of large partners to invest in or license the technology. The allosteric modulator platform is a proven asset-generating engine, which reduces the partner's internal R&D risk.

This strategic value was explicitly demonstrated by the launch of Neurosterix in 2024, a spin-off focused on developing preclinical assets from the platform. The deal structure provides ongoing value to Addex Therapeutics:

• Initial funding for Neurosterix was $63 million.
• Addex received CHF 5.0 million in cash from the transaction.
• Addex retains a 20% equity interest in Neurosterix LLC, providing a significant financial upside as those early-stage programs advance.

Also, the long-standing partnership with Indivior PLC continues to validate the platform, as Indivior advanced its GABAB PAM candidate for substance use disorders through IND-enabling studies in 2025. That's a clear vote of confidence in the underlying science.

Addex Therapeutics Ltd (ADXN) - Canvas Business Model: Customer Relationships

You're looking at Addex Therapeutics Ltd, a clinical-stage biotech, and trying to understand how they build relationships. Honestly, for a company like this, their customers aren't just patients; they are primarily their strategic partners and the capital markets. Their model is high-touch and specialized, focusing on deep, B2B (business-to-business) alliances and constant investor communication to fund their pipeline.

High-touch, dedicated relationship management with strategic partners (B2B)

The core of Addex Therapeutics' business model is leveraging its allosteric modulator platform through dedicated, high-value partnerships. This isn't a transactional relationship; it's a long-term, collaborative effort where the partner funds development and Addex retains significant upside potential. The relationship with Indivior PLC for the GABAB Positive Allosteric Modulator (PAM) program in substance use disorders is the clearest example.

Indivior successfully completed the IND-enabling studies in the first half of 2025 (H1 2025), which is a major validation point. Under this agreement, Addex is eligible for up to USD 330 million in milestone payments, plus tiered royalties on net sales ranging from high single digits up to low double digits. To be fair, the completion of the funded research phase with Indivior did cause a decrease in income of CHF 0.2 million in H1 2025 compared to the same period in 2024, so the relationship shifts from funded research to milestone management.

Another key relationship is the option agreement with Sinntaxis, entered in 2025, to license intellectual property for the use of mGlu5 Negative Allosteric Modulator (NAM) in brain injury recovery. This move is defintely a strategic way to strengthen the intellectual property (IP) around their lead candidate, dipraglurant, for post-stroke and traumatic brain injury recovery.

Here's a quick snapshot of their B2B relationship landscape in 2025:

Partner/Entity	Program/Asset	2025 Status/Update	Financial Upside/Interest
Indivior PLC	GABAB PAM for Substance Use Disorders	Completed IND-enabling studies in H1 2025.	Up to USD 330 million in milestones plus tiered royalties.
Sinntaxis	mGlu5 NAM IP for Brain Injury Recovery	Option agreement entered in 2025.	Secures and expands IP for dipraglurant program.
Neurosterix Group (Spin-out)	M4 PAM for Schizophrenia, etc.	20% equity interest held by Addex.	Non-current asset of CHF 5.8 million (as of June 30, 2025), which also includes the Stalicla investment.

Investor relations focused on clear, consistent pipeline and financial updates

Given that Addex Therapeutics is a clinical-stage company with no revenue from contracts with customers in Q1 2025, maintaining investor confidence is critical for continued funding. This relationship is managed through a rigorous schedule of financial reporting and corporate updates, aimed at a diverse spectrum of financially-literate decision-makers.

The investor relations strategy is built on transparency and forward-looking clarity, especially regarding their cash runway. As of June 30, 2025, the company reported a cash position of CHF 2.3 million. This cash is projected to sustain operations through mid-2026, which is the single most important number for investors right now.

Key investor communication events in 2025 include:

• Publication of Q1 2025 Report on June 19, 2025.
• Publication of Half-Year 2025 Report on September 30, 2025, followed by a conference call on October 1, 2025.
• Anticipated publication of the Q3 2025 Report in the week of November 10, 2025.

Patient advocacy groups for clinical trial recruitment and support

While the B2B partnerships drive the financial engine, the relationships with patient advocacy groups are essential for the clinical development pipeline. These groups are the gatekeepers to patient populations, helping to design feasible clinical trials and facilitating recruitment, which is often the biggest bottleneck in drug development.

Addex Therapeutics maintains active collaborations with patient groups and academic experts to advance its programs, particularly for rare or niche neurological disorders. This ensures that the drug candidates, like the GABAB PAM program for Charcot-Marie-Tooth 1A disorder (CMT1A) and dipraglurant for rare genetic forms of dystonia, are developed with the patient perspective front and center. This patient-centric approach helps mitigate the risk of trial failure due to poor enrollment or endpoint misalignment.

Addex Therapeutics Ltd (ADXN) - Canvas Business Model: Channels

For a clinical-stage biopharmaceutical company like Addex Therapeutics, channels are less about retail distribution and more about communicating scientific progress, securing partnerships, and raising capital. Your value proposition-novel small molecule allosteric modulators-is delivered through a highly specialized, multi-pronged approach targeting pharmaceutical partners and the capital markets.

The primary channels are direct, focusing on high-value, low-volume interactions with key industry players and investors. This is defintely a business-to-business (B2B) model, not a consumer one.

Direct licensing and collaboration agreements with pharmaceutical companies

The core channel for monetizing the drug pipeline and funding R&D is through direct strategic partnerships with larger pharmaceutical companies. These agreements serve as both a source of non-dilutive funding and a path to late-stage development and commercialization, which Addex Therapeutics does not handle internally.

For example, the collaboration with Indivior for the GABAB Positive Allosteric Modulator (PAM) program for substance use disorders has been a critical channel. While the R&D collaboration phase concluded, leading to a decrease in income by CHF 0.2 million during the six-month period ended June 30, 2025, compared to the same period in 2024, the partnership validated the allosteric modulation platform.

Key 2025 partnership channel activities include:

• Indivior: Advanced the GABAB PAM clinical candidate successfully through IND (Investigational New Drug)-enabling studies, a critical step toward clinical trials.
• Sinntaxis: Entered an option agreement for an exclusive license to intellectual property covering the use of mGlu5 Negative Allosteric Modulator (NAM), dipraglurant, in brain injury recovery.
• Janssen/J&J Innovative Medicine: Regained all development and commercialization rights to the Phase 2 mGlu2 PAM asset, ADX71149, in April 2025, following the termination of the partnership.
• Neurosterix: Maintained a strategic channel via a 20% equity interest in this spin-out company, which is advancing a separate portfolio of allosteric modulator programs.

Scientific publications and presentations at key medical conferences

To establish scientific credibility and attract potential partners, the company uses scientific channels to disseminate preclinical and clinical data. This is how the scientific community becomes aware of the drug candidates and the allosteric modulator technology.

A concrete example from 2025 is the presentation of positive GABAB PAM chronic cough data. This data, which demonstrated robust anti-tussive activity in multiple preclinical models, was presented at the 10th American Cough Conference on June 7, 2025. This presentation channel directly communicates the value of the GABAB PAM program to specialists and potential licensors in the respiratory and central nervous system (CNS) fields.

The company maintains a dedicated section on its corporate website for publications, which serves as a perpetual channel for peer-reviewed research and scientific updates.

Investor roadshows and corporate presentations to secure funding

As a NASDAQ and SIX Swiss Exchange-listed company, the capital markets are a primary channel for funding operations. This channel is crucial for maintaining a cash runway to finance ongoing R&D activities.

Investor communication is managed through scheduled financial result webcasts and conference participation. Here's the quick math on liquidity: the cash and cash equivalents stood at CHF 2.3 million at the end of the first half of 2025 (June 30, 2025). Maintaining a strong investor channel is paramount to address this cash position and secure future financing.

Key 2025 investor channel events included:

Event Type	Date	Purpose
Half-Year 2025 Financial Results Conference Call	October 1, 2025	Review of H1 2025 results and corporate update.
Q1 2025 Financial Results Conference Call	June 19, 2025	Review of Q1 2025 results; reported cash position of CHF 2.8 million.
Baader Helvea Swiss Equities Conference	January 10, 2025	Corporate presentation to institutional investors and analysts.

These events, along with the publicly available 'Addex corporate Presentation,' are the formal channels used to manage market expectations and seek non-dilutive or dilutive funding.

Regulatory submissions (NDA/BLA) for eventual market access

For a clinical-stage company, this channel is currently focused on the pre-market access stages, not final commercial approval like a New Drug Application (NDA) or Biologics License Application (BLA). The company's primary goal in this channel is to advance its drug candidates through clinical development to the point where an NDA or BLA submission becomes a realistic near-term milestone for a partner.

The most advanced regulatory channel activity in 2025 relates to the partner Indivior, which successfully completed the IND-enabling studies for the GABAB PAM program for substance use disorders. This means the program is ready for the Investigational New Drug application, which is the regulatory gateway to human clinical trials. What this estimate hides is that no final market applications are expected in the near term, as the pipeline assets are still in early to mid-stage clinical development.

Addex Therapeutics Ltd (ADXN) - Canvas Business Model: Customer Segments

You're looking at Addex Therapeutics, a clinical-stage biotech, and the core takeaway is clear: their primary customer is defintely the large pharmaceutical company. Their business model is built on de-risking novel Central Nervous System (CNS) assets, then licensing them out for significant milestone payments and future royalties. This is a classic biotech approach, so understanding the partners is the key to their near-term value.

The company's focus on allosteric modulators (drugs that bind to a receptor site different from the active site to change its function) for neurological disorders means their value proposition is highly specialized. Their customer segments reflect a multi-layered market, moving from the immediate payer (Big Pharma) to the end-user (the patient).

Large pharmaceutical and biotech companies seeking novel CNS assets (primary customer)

This segment is Addex Therapeutics' most immediate and critical revenue source, providing upfront payments, R&D funding, and future milestones. They are the true financial customers in the development phase.

Their current and recent partnership activity in 2025 clearly maps this strategy:

• Indivior PLC: This is a major active partnership for the GABAB Positive Allosteric Modulator (PAM) program targeting substance use disorders. Indivior is responsible for all downstream development. Addex is eligible for up to USD 330 million in potential regulatory and commercial milestones, plus tiered royalties on net sales from high single digit up to low double digits. This is a huge potential payday.
• Janssen Pharmaceuticals, Inc.: While Addex regained the rights to its Phase 2 mGlu2 PAM asset (ADX71149) in 2025, the original deal structure shows the customer type. That agreement made Addex eligible for up to €112 million in milestones, proving the high-value nature of their assets to Big Pharma.
• Sinntaxis: In Q1 2025, Addex entered an option agreement with Sinntaxis to explore the use of dipraglurant (mGlu5 Negative Allosteric Modulator or NAM) in brain injury recovery (post-stroke/TBI). This type of agreement is a precursor to a full licensing deal, confirming the ongoing hunt for new partners.

Here's the quick math: Addex's trailing 12-month revenue as of June 30, 2025, was only about $63.8K (in thousands, USD), which is negligible for a biotech. This low revenue number confirms that their financial model is entirely dependent on securing large, non-recurring milestone payments from these strategic partners, not from product sales yet.

Patients suffering from specific Central Nervous System (CNS) disorders

While not the immediate payer, this segment defines the ultimate market size and the value of Addex's pipeline to their pharmaceutical partners. The company focuses on areas of high unmet medical need, which translates to premium pricing and large market potential for the eventual licensee.

Their current pipeline in 2025 targets several distinct, high-impact CNS conditions:

• Substance Use Disorders (SUD): The partnered GABAB PAM program with Indivior addresses this large, chronic condition.
• Chronic Cough: Addex is advancing its own independent GABAB PAM program for this indication, which affects millions of people globally and often has limited effective treatment options.
• Brain Injury Recovery (Post-Stroke/TBI): The mGlu5 NAM program (dipraglurant) is being repositioned for this area, which represents a massive and underserved patient population requiring long-term rehabilitation.
• Mild Neurocognitive Disorders: This is a potential new indication for the Phase 2-ready ADX71149 asset, which could capture a large segment of the aging population.

The value of the drug is tied directly to the size and severity of these patient populations.

Healthcare providers (HCPs) who will eventually prescribe approved drugs

This segment acts as the gatekeeper and influencer for the final product, but only after a drug is approved and commercialized by a partner like Indivior. Their adoption determines the royalty revenue Addex will eventually receive.

HCPs, including neurologists, psychiatrists, addiction specialists, and pulmonologists, are customers of the partnering pharmaceutical company, but their needs shape Addex's development strategy today. They need drugs that offer superior efficacy and tolerability over existing treatments.

Addex's focus on allosteric modulators is a direct response to this need, aiming to develop a 'better baclofen' for substance use disorders, for example, which is a GABAB allosteric agonist with a short half-life and significant side effects. The goal is to solve the clinical problems that limit current prescription rates.

Addex Therapeutics Ltd (ADXN) - Canvas Business Model: Cost Structure

The Cost Structure for Addex Therapeutics Ltd is dominated by the fixed costs of a clinical-stage biopharmaceutical company, specifically high-risk Research and Development (R&D) and the significant overhead required for compliance and intellectual property defense. The company's financial profile for 2025 is notably lean on direct internal R&D spending due to its 2024 strategic divestiture, but the total financial burn is still substantial, with analysts forecasting a full-year net loss of approximately $7.02 million.

This is a cost-driven model, typical for a biotech firm focused on drug discovery and clinical trials. The core expenditure is on advancing its lead programs, like the GABAB positive allosteric modulator (PAM) for chronic cough and the mGlu5 negative allosteric modulator (NAM), dipraglurant, for brain injury recovery.

Heavy investment in Research and Development (R&D)

While the initial R&D projection of $18.5 million is not supported by the latest financial reports, the company's real R&D expense from continuing operations for the 2025 fiscal year is projected to be much lower, approximately $0.749 million. This sharp reduction from historical levels is a direct result of the strategic transaction in 2024, where Addex Therapeutics divested its allosteric modulator discovery platform and preclinical programs to Neurosterix Group, shifting most early-stage R&D costs off its balance sheet.

Here's the quick math: Based on the Q1 2025 R&D expense of CHF 0.156 million, and projecting that trend for the full year, the total R&D expense is estimated at CHF 0.624 million. Using the 2025 average exchange rate of 1.2006 USD/CHF, this translates to about $0.749 million. This figure represents the cost of managing the existing clinical-stage assets and any new internal research activities.

Clinical trial expenses (site fees, patient costs, monitoring)

Clinical trial expenses, the variable costs within R&D, are a critical component of the cost structure, even with the lower overall R&D budget. These costs are highly sensitive to the phase and duration of the trials for the GABAB PAM in chronic cough and the re-evaluation of dipraglurant.

• Site Fees: Payments to clinical sites and hospitals for conducting the trials.
• Patient Costs: Expenses for patient recruitment, compensation, and monitoring.
• Contract Research Organization (CRO) Fees: Outsourced costs for trial management, data collection, and statistical analysis.
• Manufacturing: Costs for producing clinical-grade drug supply.

The company is strategically minimizing these costs by focusing on a select few, high-potential clinical programs and by leveraging its partnership with Indivior, which is responsible for the development costs of its selected GABAB PAM compound for substance use disorders.

Intellectual property maintenance and legal fees

Maintaining a strong Intellectual Property (IP) portfolio is non-negotiable for a biotech company, and these costs are a mix of R&D and General and Administrative (G&A) overhead. Legal fees have been a focus for cost reduction.

• Patent Filings: Costs for global patent application, defense, and maintenance fees across multiple jurisdictions for key assets.
• Litigation Risk: Costs associated with defending or enforcing patents, a perennial risk in the pharmaceutical sector.

The G&A expenses saw a reported decrease of CHF 0.4 million in the first half of 2025 compared to the same period in 2024, primarily due to reduced legal fees, suggesting a successful effort to control this specific overhead cost. Still, you have to defintely budget for IP defense.

General and administrative (G&A) overhead (e.g., executive salaries, compliance)

General and administrative expenses cover the necessary fixed costs to keep the company operational and compliant with regulatory bodies like the SIX Swiss Exchange and NASDAQ. For 2025, G&A is projected to be approximately $2.502 million.

This includes the salaries for executive and administrative staff, compliance costs for being a publicly listed company in both Switzerland and the US, and general office overhead. The full-year 2024 G&A was CHF 2.3 million, and the Q1 2025 figure of CHF 0.521 million suggests a slight projected decrease for 2025, which is a positive sign of tight cost control.

A key financial component in the overall burn is the investment loss from the Neurosterix spin-out. The company holds a 20% equity interest in Neurosterix US Holdings LLC, and the share of the net loss from this investment significantly contributes to the total net loss, which analysts forecast to be around $7.02 million for 2025. This shows the true cost of maintaining the business model extends beyond the internal R&D and G&A line items.

Cost Category (Continuing Operations)	2024 Full Year (CHF millions)	2025 Full Year Projection (USD millions)	Primary Nature
Research and Development (R&D) Expenses	CHF 0.8 million	$0.749 million	Variable (Clinical Trials, Outsourced Research)
General and Administrative (G&A) Overhead	CHF 2.3 million	$2.502 million	Fixed (Salaries, Compliance, Legal)
Share of Net Loss of Investments (Neurosterix)	CHF 2.2 million	N/A (Included in Net Loss)	Fixed/Equity Method Accounting
Total Net Loss (Analyst Forecast)	CHF 4.9 million (Continuing Ops)	$7.02 million	Total Financial Burn

Addex Therapeutics Ltd (ADXN) - Canvas Business Model: Revenue Streams

The revenue model for Addex Therapeutics is a classic, high-risk, high-reward biotech structure, heavily reliant on non-recurring, lump-sum payments from strategic partnerships and future royalties, rather than product sales. The near-term focus is on securing new upfront payments to extend the cash runway beyond the current mid-2026 projection.

Upfront payments and milestone payments from strategic collaborations, estimated at $5.0 million in 2025

Your goal of securing a $5.0 million upfront payment in 2025 is a critical strategic target, but it's important to be a realist: the actual income from continuing operations in the first half of 2025 (H1 2025) was significantly lower, at only CHF 0.107 million (approximately $118,000). This income primarily came from collaboration revenue, which has decreased since the research phase of the Indivior agreement concluded in mid-2024. Securing a new, large upfront payment is the only way to bridge that gap. The recent regaining of rights to the Phase 2 asset ADX71149, for which management is actively seeking a new partner, represents the clearest opportunity for a multi-million-dollar upfront payment.

Here's the quick math on the current revenue reality versus the strategic goal:

Revenue Stream Category	H1 2025 Actual Income (CHF)	Strategic Goal / Potential
Collaboration Income (Upfront/Milestone/Research)	CHF 107,000	Targeting a new upfront payment of $5.0 million
Primary Source of H1 2025 Income	Existing service and collaboration agreements	New partnership for ADX71149 or other pipeline assets

Potential future royalties on net sales of approved partnered products

This is where the long-term, defintely life-changing value lies. Your strategic partnerships, especially the one with Indivior for the GABAB Positive Allosteric Modulator (PAM) program for substance use disorders, carry the promise of substantial future revenue. Indivior has advanced its clinical candidate through IND-enabling studies, which is a major validation milestone.

The financial terms of this collaboration are significant:

• Addex is eligible for up to USD 330 million in development and commercial milestone payments.
• You also stand to receive tiered royalties on the net sales of any approved product resulting from the collaboration.

These royalties, which are a percentage of sales once a drug hits the market, will be the first true, recurring product-based revenue stream. Until then, it's all about milestone payments tied to clinical and regulatory progress.

Research funding and grants from government or non-profit organizations

While not a primary driver of large-scale revenue, grants and targeted research funding help offset the high cost of preclinical development. Historically, the company's 'Income' line item, which includes collaboration revenue and any grants, has been small and volatile. The completion of the R&D phase with Indivior has reduced this income source, as seen by the H1 2025 income of CHF 0.107 million being lower than prior periods. This type of funding is crucial for maintaining internal programs like the GABAB PAM candidate for chronic cough, which is currently an in-house asset. You must continue to aggressively pursue non-dilutive grants to fund preclinical work, freeing up precious cash for clinical studies.

Equity financing (dilutive funding) to extend the cash runway

For a clinical-stage biotech, equity financing-selling shares to raise capital-is a necessary, though dilutive, revenue stream used to extend the cash runway (the time until the company runs out of money). As of June 30, 2025, the company's cash and cash equivalents stood at CHF 2.3 million. This cash position is projected to fund operations through mid-2026. To be fair, the prior transaction with Neurosterix in 2024, which generated CHF 5.0 million in cash proceeds, significantly extended the runway without immediate, further dilution in 2025. Still, without a new major partnership, expect a fresh equity raise in late 2025 or early 2026 to push the runway into 2027. This is a clear action item: Finance needs to model a new financing round now.
