Financial Summary:

Income decreased by CHF 0.7 million to CHF 3.2 million in 2021 compared to CHF 3.9 million in 2020, primarily due to amounts received under the licensing and research agreement with Indivior, recognized as related costs are incurred.

R&D costs increased by CHF 2.4 million to CHF 12.8 million in 2021 compared to CHF 10.4 million in 2020, mainly due to increased outsourced R&D expenses for CHF 2.0 million of which CHF 0.6 million relates to our dipraglurant PD-LID program and CHF 0.6 million for our dipraglurant blepharospasm program. 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 remained stable around CHF 5.8 million in 2021 and 2020.

The net loss was CHF 15.4 million in 2021 compared to CHF 12.9 million in 2020 primarily due to increased R&D expenses. Basic and diluted loss per share decreased to CHF 0.45 for the year ended December 31, 2021, compared to CHF 0.48 for the year ended December 31, 2020.

Cash and cash equivalents increased to CHF 20.5 million at December 31, 2021, compared to CHF 18.7 million at December 31, 2020. This increase of CHF 1.8 million is mainly due to the two offerings executed on January 8, 2021 and December 16, 2021 for total net proceeds of CHF 16 million partially offset by our net loss of CHF 15.4 million. During the same period, non-cash items mainly relating to the value of share-based services amounted to CHF 1.4 million have been partially off-set by the net effect of the increased net working capital of CHF 0.6 million.

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 in a pivotal registration clinical trial for Parkinson’s disease levodopa induced dyskinesia (PD-LID) and has entered a Phase 2 clinical study for the treatment of blepharospasm, a form of dystonia. Addex's third clinical program, ADX71149 (mGlu2 positive allosteric modulator or PAM), developed in collaboration with Janssen Pharmaceuticals, Inc., is in a Phase 2a proof of concept clinical trial for the treatment of epilepsy. Indivior PLC has licensed Addex’s GABAB PAM program for the development of drug candidates with a focus in 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 shares are listed on the SIX Swiss Exchange and American Depositary Shares representing its shares are listed on the NASDAQ Capital Market, and trade under the ticker symbol "ADXN" on each exchange.
