Financial Summary:

Income increased by CHF 1.0 million to CHF 3.9 million in 2020 compared to CHF 2.8 million in 2019, primarily due to amounts received under the licensing and research agreement with Indivior, recognized as related costs are incurred.

R&D expenses decreased by CHF 2.1 million to CHF 10.4 million in 2020 compared to CHF 12.4 million in 2019, primarily due to delays in starting certain clinical development activities due to the global coronavirus pandemic. 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 CHF 0.7 million to CHF 5.7 million in 2020 compared to CHF 5.0 million in 2019 mainly due to the increase of CHF 1.3 million relating to increased directors and officer’s liability insurance premiums partially offset by a decrease of CHF 0.5 million in audit and legal fees.

The net loss for 2020 was CHF 12.9 million compared to CHF 14.8 million for 2019 primarily due to the decrease in R&D costs. Basic and diluted loss per share decreased to CHF 0.48 for 2020, compared to CHF 0.56 for 2019.

Cash and cash equivalents amounted to CHF 18.7 million at December 31, 2020 compared to CHF 31.5 million at December 31, 2019. This decrease of CHF 12.8 million is mainly due to the net loss.

About Addex Therapeutics:

Addex Therapeutics is a clinical-stage pharmaceutical company focused on the development and commercialization of an emerging class of novel orally available small molecule drugs known as allosteric modulators for neurological disorders. Allosteric modulators offer several potential advantages over conventional non-allosteric molecules and may offer an improved therapeutic approach to 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. Addex's lead drug candidate, dipraglurant (mGlu5 negative allosteric modulator or NAM), is poised to start a pivotal registration clinical trial for Parkinson’s disease levodopa induced dyskinesia (PD-LID) in H1 2021. Addex is also investigating dipraglurant's therapeutic use in blepharospasm (a type of dystonia), for which a clinical trial is expected to be initiated in H1 2021. Addex's third clinical program, ADX71149 (mGlu2 positive allosteric modulator or PAM), developed in collaboration with Janssen Pharmaceuticals, Inc, is scheduled to enter a phase 2a proof of concept clinical study for the treatment of epilepsy in Q2 2021. Addex’s GABAB PAM program has been licensed to Indivior PLC who are focused on development for the treatment of addiction. Preclinical programs include GABAB PAM for CMT1A, mGlu7 NAM for PTSD, mGlu2 NAM for mild neurocognitive disorders, mGlu4 PAM for Parkinson’s disease and mGlu3 PAM for neurodegenerative disorders. Addex is listed on the SIX Swiss Exchange and the NASDAQ Capital Market and trades under the ticker symbol "ADXN".
