Addex Therapeutics Ltd (NASDAQ:ADXN) is a clinical-stage biopharmaceutical company headquartered in Geneva, Switzerland, focused on discovering and developing innovative oral allosteric modulators for neurological disorders and diseases of the central nervous system. Founded with the vision of transforming how brain disorders are treated, the company has established itself as a pioneer in the field of allosteric modulation, a cutting-edge approach that enhances or regulates the body’s natural receptor responses rather than directly activating them, offering a potentially safer and more targeted therapeutic benefit. Addex’s proprietary platform is built on decades of research into metabotropic glutamate receptors (mGluRs) and gamma-aminobutyric acid receptors (GABAB), two critical components involved in brain signaling and neurological function. By creating small molecules that act as positive or negative allosteric modulators, Addex aims to deliver precision therapies that address the underlying mechanisms of diseases such as epilepsy, anxiety, addiction, Parkinson’s disease, pain, and other neuropsychiatric disorders.
Over the years, Addex Therapeutics has built strategic partnerships with major pharmaceutical companies and research institutions to advance its clinical programs and expand its therapeutic reach. The company’s most advanced programs include drug candidates targeting the mGlu2 and GABAB receptors for the treatment of substance use disorders, epilepsy, and schizophrenia. Addex’s collaboration with Indivior on GABAB positive allosteric modulators is a key component of its strategy, leveraging combined expertise to accelerate development for addiction-related indications. In addition, Addex has regained full rights to certain pipeline assets, including its mGlu2 program, creating opportunities for future licensing and strategic development in multiple therapeutic areas. This strategic control, along with its investment in precision medicine ventures such as Stalicla, positions the company to evolve as both a platform developer and a clinical innovator in the neuroscience field.
Addex Therapeutics operates within a rapidly growing market environment driven by increasing global awareness of neurological disorders, unmet patient needs, and emerging regulatory support for novel therapies. With a proprietary drug discovery platform, a strong intellectual property portfolio, and a pipeline focused on high-value therapeutic targets, the company is strategically positioned to advance breakthroughs that have the potential to redefine standard-of-care treatments in brain health. As it moves toward clinical milestones and commercialization opportunities through partnerships and licensing agreements, Addex continues to solidify its role as a key player in the future of innovative neurological therapeutics.
Strategic Milestones Demonstrate Clinical Progress and Commercial Readiness
Addex successfully completed IND-enabling studies for its GABAB positive allosteric modulator (PAM) drug candidate developed in partnership with Indivior. This drug is targeting substance use disorders, one of the largest global health and economic burdens, representing a multibillion-dollar market with limited efficacious treatments. This milestone brings Addex one step closer to entering the clinic, unlocking the potential for clinical trial initiation and triggering lucrative milestone payments. The partnership with Indivior gives Addex access to up to USD 330 million in potential milestone revenue, a transformative opportunity that could significantly de-risk the company’s balance sheet and fund further innovation.

Strategic Control of High-Value Pipeline Assets Unlocks Long-Term Value
In a major strategic advancement, Addex regained full rights to its mGlu2 positive allosteric modulator program from Johnson & Johnson, including the Phase II-ready ADX71149 program. This positions Addex to independently advance this candidate or re-partner it under more favorable financial terms. The mGlu2 receptor is implicated in multiple central nervous system disorders, including schizophrenia, anxiety, and chronic pain. Regaining control of this asset empowers Addex to explore multiple high-value indications with significant commercial potential, strengthening the company’s intellectual property portfolio and strategic optionality.
Financial Restructuring Creates a More Sustainable Growth Runway
The company reported a cash reserve of CHF 2.3 million, providing operational runway through mid-2026. Following the Neurosterix spin-out, Addex substantially reduced its cash burn, demonstrating disciplined financial stewardship. This financial restructuring improves capital efficiency and ensures that available cash is allocated to programs with the highest commercial return potential. Although income decreased by CHF 0.1 million due to the completion of certain funded research activities, the strategic realignment places Addex in a stronger position to pursue milestone payments and secure new partnerships.
Near-Term Challenges Paired With Long-Term Catalysts
Despite reporting an increased net loss from Neurosterix, with Addex’s share of loss rising to CHF 1.2 million in Q2, this is largely attributable to upfront development investments that could generate long-term value. The limited cash available for unpartnered programs highlights the importance of near-term milestone achievements and external financing. However, the company’s leadership openly acknowledges this challenge and is actively pursuing capital-efficient strategies, including non-dilutive funding from partnerships, grants, and strategic collaborations.
Positioned for Value Creation Through Partnership Strategy
Addex’s future growth potential is underpinned by its ability to monetize its innovative pipeline through partnerships. In addition to the Indivior collaboration, the company’s investment in Stalicla demonstrates strategic alignment with precision medicine. Stalicla’s focus on patient stratification in neurodevelopmental disorders complements Addex’s own platform, creating synergistic opportunities in personalized neuroscience. These relationships enhance Addex’s pipeline value and offer potential for future equity appreciation tied to partner success.
Outlook: Catalysts Poised to Unlock Significant Shareholder Value
Looking ahead, Addex is entering a catalyst-rich period. The company’s GABAB PAM program could initiate clinical trials soon, triggering milestone payments and generating investor enthusiasm. The independent GABAB PAM program for chronic cough is progressing through preclinical development, targeting a market with massive unmet demand. Although Addex acknowledges the need for additional financing to advance unpartnered programs, the company’s improved cash burn rate and strong partnership potential place it in a position of strategic advantage.
Addex Therapeutics presents a classic high-risk, high-upside biotech opportunity. Investors are closely watching the company’s next steps as it seeks to monetize its pipeline through partnerships, initiate key clinical trials, and potentially deliver non-dilutive capital infusions. With a differentiated scientific platform, multiple upcoming catalysts, and strong positioning in high-growth neurological markets, Addex Therapeutics is increasingly viewed as a speculative biotech with transformational upside potential.
