Geneva, Switzerland, September 30, 2025-Addex Therapeutics(SIX and Nasdaq: ADXN), a clinical-stage biopharmaceutical company focused on developing a portfolio of novel small molecule allosteric modulators for neurological disorders, today reported its half-year and second quarter financial results for the periods ended June 30, 2025, and provided a corporate update.
"We have seen great progress in the first six months of 2025, both in terms of drug candidate development and achieving business milestones. In particular, progress continues well and on track with our GABAB PAM drug candidate in chronic cough. We also presented positive data from the cough program, achieved in multiple preclinical models, at the prestigious American Cough conference. We also regained rights to our Phase 2 mGlu2 PAM asset, ADX71149, for which we are evaluating next steps for the program internally," said Tim Dyer, CEO of Addex. "Solidifying our position to use mGlu5 NAMs in brain injury, we entered an option agreement with Sinntaxis to gain access to additional intellectual property in the field. Our plan is to explore further the clinical activity of dipraglurant in this indication. Our partner, Indivior, has advanced its GABAB PAM clinical candidate through IND enabling studies, providing additional validation of our allosteric modulation approach. We also led a financing in Stalicla, a Swiss company pioneering a precision medicine approach for neurodevelopmental and neuropsychiatric disorders. Following the spin-out of Neurosterix last year, this investment continues to underscore our commitment to advancing innovative treatments for CNS disorders."

Financial Summary:
Income decreased by CHF 0.2 million during the six-month period ended June 30, 2025 compared to the same period ended June 30, 2024, primarily due to the completion of the R&D collaboration phase of our agreement with Indivior.
R&D expenses decreased by CHF 0.2 million during the six-month period ended June 30, 2025 compared to the same period ended June 30, 2024, primarily due to lower GABAB PAM outsourced R&D expenses related to our R&D collaboration agreement with Indivior.
G&A expenses decreased by CHF 0.4 million during the six-month period ended June 30, 2025 compared to the same period ended June 30, 2024, primarily due to reduced legal fees.
The net result decreased by CHF 13.1 million during the six-month period ended June 30, 2025 compared to the same period ended June 30, 2024, primarily due to gross proceeds of CHF 14.0 million from the sale of a part of our business executed on April 2, 2024 and recognized as discontinued operations. During the same period ended June 30, 2025, the net loss from continuing operations increased by CHF 1.2 million primarily due to an increased share of loss from the investment in Neurosterix US Holdings accounted for using the equity method since April 2, 2024.
