Financial Summary

Revenue in 2018 was CHF6.0 million and relates to upfront fees and research funding recognized under our license and research agreement with Indivior PLC. Other income in 2018 was CHF0.7 million compared to CHF0.5 million in 2017, and comprises primarily grants from The Michael J. Fox Foundation for Parkinson’s Research related to dipraglurant development in PD-LID and TrKB PAM discovery activities.

R&D expenses increased by CHF2.3 million to CHF4.9 million in 2018 compared to CHF2.6 million in 2017, mainly due to manufacturing and consulting activities related to the preparation of dipraglurant PD-LID registration studies as well as research activities related to our GABAB PAM and TrKB PAM programs. R&D expenses consist primarily of costs associated with research, preclinical and clinical testing and related staff costs. They also include depreciation of laboratory equipment, costs of materials used in research, costs associated with renting and operating facilities and equipment, as well as fees paid to consultants, patent costs and other outside service fees and overhead costs. These expenses include costs for proprietary and third party R&D.

G&A expenses increased by CHF2.1 million to CHF3.2 million in 2018, compared to CHF1.1 million in 2017, mainly due to the recognition of the fair value of equity incentive units granted during the year of CHF1.4 million compared to CHF0.3 million in 2017. Other G&A expenses consist primarily of staff costs, professional fees for legal, tax and strategic purposes and overheads related to general management, human resources, finance, information technology, business development and communication functions.

The net loss for 2018 was CHF1.6 million compared to CHF3.2 million for 2017. Basic and diluted loss per share decreased to CHF0.07 for 2018, compared to CHF0.25 for 2017.                    

Cash and cash equivalents amounted to CHF41.7 at December 31, 2018 compared to CHF2.6 million in 2017. This increase is primarily due to the gross proceeds from the CHF40 million capital increase completed on 28 March 2018.

About Addex Therapeutics

Addex Therapeutics ( is a biopharmaceutical company focused on the development of novel, orally available, small molecule allosteric modulators for neurological disorders. Allosteric modulators are an emerging class of small molecule drugs which have the potential to be more specific and confer significant therapeutic advantages over conventional "orthosteric" small molecule or biological drugs. Addex's allosteric modulator drug discovery platform targets receptors and other proteins that are recognized as essential for therapeutic intervention - the Addex pipeline has been generated from this pioneering allosteric modulator drug discovery platform. Addex's lead drug candidate, dipraglurant (mGluR5 negative allosteric modulator or NAM) has successfully completed a Phase 2a POC in Parkinson's disease levodopa-induced dyskinesia (PD-LID), and is being prepared to enter registration trials for PD-LID. In parallel, dipraglurant's therapeutic use in dystonia is being investigated. Addex's second clinical program, ADX71149 (mGluR2 positive allosteric modulator or PAM) is being developed in collaboration with Janssen Pharmaceuticals, Inc for epilepsy. In addition, Addex’s GABAB PAM program has been licensed to Indivior PLC for the treatment of addiction. Discovery programs include mGluR4PAM, mGluR7NAM, mGluR3PAM and TrkBPAM.
