Addex Therapeutics Ltd (ADXN): ANSOFF MATRIX [Dec-2025 Updated]

You're looking at Addex Therapeutics Ltd (ADXN) and the clock is defintely ticking; with only CHF 2.3 million in cash as of mid-2025, the margin for error is razor-thin. Your primary goal isn't just to survive a CHF 0.03 net loss per share from H1 2025, but to surgically convert clinical assets into immediate value, so we need a strategy that maps near-term partnerships and low-cost pivots to extend the runway. This isn't a time for vague R&D; it's about using the Ansoff Matrix to pinpoint exactly where to push the GABAB PAM program for chronic cough and how to leverage dipraglurant's existing data for a high-value market development play.

Addex Therapeutics Ltd (ADXN) - Ansoff Matrix: Market Penetration

Market Penetration for Addex Therapeutics is about maximizing the value of your existing drug candidates-specifically the GABAB Positive Allosteric Modulator (PAM) programs-within your core market of neurological disorders. This strategy demands ruthlessly accelerating the most promising wholly-owned assets while using partnerships to shoulder the cost and de-risk the pipeline.

You're operating with a tight cash runway; your cash and cash equivalents stood at CHF 2.8 million at the end of Q1 2025, which is projected to fund operations only through mid-2026. Honestly, that is not a lot of time. So, every dollar must be spent to hit a value inflection point that triggers a significant partnership or milestone payment.

Accelerate IND-enabling studies for the GABAB PAM chronic cough candidate

Your primary, wholly-owned focus must be the GABAB PAM chronic cough candidate. Preclinical data, presented in June 2025, showed robust anti-tussive activity in multiple models of chronic cough, appearing superior to reference drugs like nalbuphine and codeine, and demonstrating a wider therapeutic margin than the GABAB agonist baclofen. This is a big deal.

The candidate is ready to start Investigational New Drug (IND)-enabling studies, a critical step before human trials. You must push this program forward now, as a successful preclinical package is the key asset for the next step in market penetration: securing a commercial partner.

Secure a US-centric commercial partner for the GABAB PAM chronic cough program

The current cash position of CHF 2.8 million at the end of Q1 2025 is insufficient to fund the chronic cough program into the clinic. You need a partner to bridge this gap. Securing a US-centric commercial partner is crucial, and the goal is to target a significant upfront payment to extend the cash runway past mid-June 2026.

What this estimate hides is that the size of the upfront payment will defintely be tied to the strength of the IND-enabling data. A successful partnership is the only near-term financial action that prevents immediate dilution risk.

Support Indivior's GABAB PAM substance use disorders program to rapidly trigger development milestones

Your partnership with Indivior is a validated source of non-dilutive capital. Indivior has already successfully advanced its GABAB PAM substance use disorders program through IND-enabling studies, a major achievement announced in May 2025. Your job is to support their work to accelerate their clinical entry, which will rapidly trigger development milestones.

Here's the quick math on the potential value of this existing market penetration effort:

Focus R&D spending solely on advancing the lead wholly-owned assets

With a lean operating budget, R&D spending must be laser-focused. For Q1 2025, R&D expenses were reported at approximately CHF 156,066. You must maintain this financial discipline, directing nearly all of it toward the chronic cough program to reach the value inflection point for a partnership.

This means deprioritizing all other early-stage research that does not contribute directly to the chronic cough IND package or the Indivior milestones. Every Swiss franc counts right now.

• Prioritize: Complete the chronic cough IND-enabling studies in 2025.
• Action: Secure a US partner for the chronic cough program to inject capital.
• Goal: Trigger the next Indivior milestone payment by supporting their clinical start.

Addex Therapeutics Ltd (ADXN) - Ansoff Matrix: Market Development

Market Development for a clinical-stage biotech like Addex Therapeutics isn't about opening new geographic offices; it's about taking an existing, proven compound and pivoting it to a new, high-value indication where the unmet medical need is substantial. This is a low-cost way to get a new shot on goal, especially when your cash position is tight, which for Addex was CHF 2.3 million at the end of H1 2025. You are essentially repurposing the safety and tolerability data you already paid for.

Initiate clinical pharmacology studies for dipraglurant (mGlu5 NAM) in the new indication of brain injury recovery, leveraging the option agreement with Sinntaxis for exclusive intellectual property.

Your most immediate and focused Market Development play is repositioning dipraglurant (a metabotropic glutamate receptor subtype 5 negative allosteric modulator, or mGlu5 NAM) for post-stroke and traumatic brain injury (TBI) recovery. This is a smart move because there are currently no approved drugs to support sensorimotor recovery after a stroke; current therapy relies on lengthy physiotherapy. The market need is massive: the World Stroke Organization reports over 12.2 million strokes each year globally, which represents a significant commercial opportunity for a first-in-class drug.

The key action here is leveraging the option and collaboration agreement Addex entered into with Sinntaxis AB in April 2025. This deal gives Addex an exclusive license to Sinntaxis's intellectual property (IP) covering the use of mGlu5 inhibitors for brain injury recovery. Sinntaxis is now executing a research plan to complete the preclinical validation of dipraglurant in models of brain injury recovery, building on existing published data.

• Complete preclinical validation of dipraglurant in brain injury models with Sinntaxis.
• Secure the necessary funding to commence the planned Phase 2a study for post-stroke recovery.
• The mechanism of action, stimulating network connectivity in the brain, has already shown significant restoration of functional control in preclinical stroke models after just three days of treatment.

Target rare disease designations (orphan drug status) for dipraglurant in brain injury recovery to streamline the regulatory path and secure market exclusivity. I defintely think this is critical.

For a company with a market capitalization of only $9.1 million as of October 29, 2025, the Orphan Drug Designation (ODD) strategy is a financial necessity. Targeting a subset of brain injury recovery, such as a specific type of TBI or stroke-related motor deficit, that qualifies as a rare disease (affecting fewer than 200,000 people in the US) provides a clear path. ODD status can streamline the regulatory process, grant assistance in clinical trial design, and, most importantly, secure up to seven years of market exclusivity in the US after approval.

Here's the quick math on why this matters: it reduces the financial burn rate by potentially lowering user fees and securing tax credits related to development expenses, which is vital when your H1 2025 net loss per share was CHF 0.03.

Re-evaluate the Phase 2 mGlu2 PAM asset, ADX71149, for new neurological indications beyond its previous use in epilepsy, schizophrenia, or anxious depression, now that the rights have been regained.

The regaining of all rights to ADX71149 (mGlu2 positive allosteric modulator, or PAM) from Janssen Pharmaceuticals, Inc. in April 2025 is a major Market Development opportunity. This asset is a high-quality compound that has completed three Phase 2 studies in previous indications, which means you have a robust data package on safety and tolerability.

The company is currently evaluating a number of high-value therapeutic indications for the future development of the program. You need to look for indications where mGlu2 PAMs are mechanistically relevant, such as certain forms of psychosis, anxiety disorders, or even mild neurocognitive disorders, which are areas the company has previously explored.

Leverage the existing Phase 2 data package for ADX71149 to attract a new, indication-specific partner for a high-value central nervous system (CNS) disorder.

The most capital-efficient action is not to fund the next clinical trial yourself, given your limited cash reserves. You need to leverage the existing Phase 2 data package-which includes results from trials in epilepsy, schizophrenia, and anxious depression-to secure a new, indication-specific partner. The previous partnership with Janssen Pharmaceuticals, Inc. was structured to offer up to €109 million in success-based milestones, plus low double-digit royalties. This is the financial model you must replicate.

The goal is to find a partner who sees the value in the mGlu2 PAM mechanism for a specific, high-unmet-need CNS disorder that aligns with their own pipeline. This immediately shifts the development cost burden and risk off the Addex balance sheet, which is critical when your primary focus must be on extending your cash runway.

Addex Therapeutics Ltd (ADXN) - Ansoff Matrix: Product Development

You need to replenish the pipeline with new molecules targeting your core neurological disorders market, especially since the net loss per share was CHF 0.03 in H1 2025. This is a crucial, long-term R&D strategy that demands capital allocation to preclinical assets that can replace terminated or out-licensed programs. Your focus must be on advancing the most promising allosteric modulator (PAM/NAM) candidates toward Investigational New Drug (IND) enabling studies.

Here's the quick math: your cash and cash equivalents stood at only CHF 2.3 million at the end of H1 2025. This tight liquidity means every R&D dollar must be spent on programs with the clearest path to clinical validation or partnership, primarily through your independent pipeline and the Neurosterix US Holdings LLC investment.

Prioritize the mGlu4 PAM Program for Parkinson's Disease (PD)

The mGlu4 positive allosteric modulator (PAM) program, which is part of the Neurosterix US Holdings LLC portfolio, is your key strategic replacement for the terminated dipraglurant PD-LID (Parkinson's disease levodopa-induced dyskinesia) program. This asset aims to offer a non-dopaminergic approach to treating PD symptoms. Since you hold a 20% equity interest in Neurosterix, its success directly impacts your valuation.

• Action: Push the mGlu4 PAM program toward the final preclinical stage, aiming for IND-enabling studies to be initiated by the end of 2025.

• Risk: Your net loss from continuing operations increased in H1 2025, primarily due to an increased share of loss from the Neurosterix investment, totaling an increase of CHF 1.2 million. What this estimate hides is the cash burn risk if Neurosterix requires a follow-on financing round sooner than expected.

Advance the mGlu7 NAM Preclinical Program for PTSD

The mGlu7 negative allosteric modulator (NAM) program, targeting post-traumatic stress disorder (PTSD), remains a high-need area within your central nervous system (CNS) focus. This program, also housed within the Neurosterix portfolio, is built on earlier work that received a substantial non-dilutive grant of €4.85 million (approximately $5.2 million).

• Strategic Focus: mGlu7 NAMs are designed to precisely modulate brain circuits involved in fear and anxiety, potentially offering higher efficacy and fewer side effects than current unspecific medications.

• Goal: Achieve a clear preclinical candidate selection milestone within the next 12 months, leveraging the initial grant-funded data to minimize immediate internal R&D expenditure.

Fund the Most Promising Neurosterix Preclinical Programs

Your equity investment in Neurosterix US Holdings LLC is a critical lever for product development, giving you exposure to a broader preclinical portfolio without bearing 100% of the R&D cost. The mGlu2 NAM for mild neurocognitive disorders (MND) is one such program, building on earlier work that received a €4 million Eurostars grant.

To be fair, the investment is a double-edged sword, as your share of the net loss of the Neurosterix Group was a significant contributor to your H1 2025 financial results. Still, this is how you maintain a broad, early-stage pipeline.

Use Your Allosteric Modulator Platform for Chronic Cough

Your independent GABAB PAM program for chronic cough is the most advanced preclinical asset, demonstrating the power of your allosteric modulator (a molecule that binds to a receptor at a site other than the main binding site) platform. Preclinical data from June 2025 showed that the GABAB PAM candidate had robust anti-tussive activity in multiple chronic cough models, appearing superior in efficacy to reference drugs like nalbuphine and codeine.

• Next Step: Immediately fund the final IND-enabling studies for this GABAB PAM candidate.

• Competitive Edge: Targeting the allosteric site is expected to provide better tolerability and a wider therapeutic margin than orthosteric compounds like baclofen, which is used off-label but limited by serious side effects. This is a defintely a high-value, near-term catalyst for the company.

Addex Therapeutics Ltd (ADXN) - Ansoff Matrix: Diversification

This is the highest-risk, highest-reward quadrant. For a clinical-stage biotech with limited revenue, the best form of diversification is a strategic platform application or a new therapeutic class via a strong partner. You need to generate non-dilutive capital and access new, large markets. The current trailing 12-month (TTM) revenue is only $63.8K, so any new, large revenue stream is a critical diversification move.

Strategic Out-Licensing of Retained Allosteric Modulators (New Product/New Market)

The most immediate diversification opportunity is licensing a retained clinical-stage asset to a partner focused on a non-CNS indication. While the core allosteric modulator discovery platform was divested to Neurosterix US Holdings LLC, Addex Therapeutics retained key clinical-stage compounds like its GABAB Positive Allosteric Modulator (PAM) program.

You should explore a non-respiratory out-licensing deal for the GABAB PAM. The GABAB receptor is implicated in areas like pain, inflammation, and certain gastrointestinal disorders, which are massive markets. Securing an upfront payment here diversifies your revenue away from the current low base and extends the cash runway beyond the Q2 2025 balance of CHF 2.3 million. It's a smart way to get non-dilutive funding, honestly.

• License the GABAB PAM asset for a non-CNS indication (e.g., chronic pain or inflammatory bowel disease) to secure an upfront payment and milestone fees.
• The Chronic Refractory Cough market, the current focus of the GABAB PAM, is projected to be worth $6.23 billion in 2025, offering a substantial non-core CNS market opportunity.
• Target a deal structure of $5 million to $10 million upfront, plus downstream royalties, to immediately bolster the balance sheet.

Deepening Precision Medicine Investment in Stalicla SA (New Product/New Market Niche)

Your CHF 2 million investment in Stalicla SA in June 2025 is a key diversification action, shifting part of your focus into the specialized, high-growth area of precision medicine for neurodevelopmental disorders (NDD). Stalicla's approach to Autism Spectrum Disorder (ASD) is to treat stratified patient subgroups, which is a new product niche within the broader CNS market.

The global ASD therapeutics market is valued at approximately $2.34 billion in 2025 and is projected to grow at a CAGR of 5.29%. This is a significant, underserved market that requires a precision approach, which Stalicla's DEPI (Databased Endophenotyping Precision Identification) platform provides. This investment is a low-capital entry point into a high-value segment, and you should defintely look to increase your stake or co-develop a compound.

Monetizing the Neurosterix US Holdings LLC Financial Stake

While Neurosterix is focused on neurological disorders (CNS), your 20% equity interest acts as a powerful financial diversification tool. The company was launched with $63 million in initial funding, validating the core allosteric modulator platform Addex Therapeutics pioneered. The diversification here is purely financial, converting a portion of your R&D investment into a valuable, non-controlling asset.

Here's the quick math: Neurosterix's initial valuation is substantial, and Addex Therapeutics is entitled to a share of its future value. The immediate action is to track the progress of Neurosterix's lead program, NTX-253 (M4 PAM for schizophrenia), which is planned to enter first-in-human clinical trials in late 2025. Hitting that milestone will increase the value of your 20% stake, which is a clean, non-operational revenue driver.

What this estimate hides is the potential for a massive, multi-billion dollar exit for Neurosterix, which would deliver a windfall to your 20% stake. Still, the near-term focus must be on the GABAB PAM out-licensing to secure that non-dilutive cash, which is a clear action.

Next Step: Business Development: Initiate non-CNS GABAB PAM out-licensing discussions with three mid-to-large pharma companies by the end of Q4 2025.
