ADX48621 Overview • Phase I completed • Three studies: SAD, MAD, gender & food effects • 110 patients treated to date, including older volunteers • Safety & tolerability justify further clinical study • Differentiated • Only product shown to reduce dystonia in MPTP model • Chemical series unrelated to other mGluR5 NAM • Unique metabolic profile • NCE patents valid through 2025 in most territories • Unrelated series of backup molecules in clinical candidate selection
**p<0.01, ***p<0.001 versus vehicle group ADX48621 efficacy in HIC model • Haloperidol induced catalepsy (HIC) is a preclinical model of PD • ADX48621 dose-dependently reversed HIC in 3 independent experiments • MTEP mGluR5 antagonist is well documented to work in the HIC model • ADX48621 effects in HIC model suggest • It should be tested further as a potential drug for PD • It has potential to be a dopamine sparing agent
MPTP model of PD-LID What is the MPTP Model? • MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) • Neurotoxin destroys dopaminergic neurons • Symptoms similar to PD, treatable with levodopa • MPTP monkeys develop levodopa induced dyskinesia (LID) • MPTP PD-LID model is predictive of efficacy in humans • AFQ056 (mGluR5/Novartis) showed efficacy in MPTP PD-LID model • AFQ056 showed efficacy in Phase IIa PD-LID trial
ADX48621 MPTP Study Design • ADX48621 or vehicle administered 30 min prior to levodopa • Behavioral assessment began upon levodopa administration • trained observers performed video review • dyskinesia & disability scoring (first 10 min of every 30 min for 2hrs) • lower scores (left axis) indicate fewer symptoms/disability • dyskinesia symptoms are side effect of levodopa • disability is a measure of Parkinson’s disease severity
Disability Dyskinesia + levodopa ADX48621 does not reduce levodopa efficacy ADX48621 dose-dependently reduced dyskinesia (chorea + dystonia) ADX48621 efficacy in MPTP model ADX48621 reduced dyskinesia without compromising levodopa efficacy
Chorea Dystonia Dystonia = sustained muscle contractions (e.g. cramps) Chorea = involuntary movements (e.g. trembling) ADX48621 efficacy in MPTP model ADX48621 is the first drug-candidate known to have efficacy on dystonia
ADX48621development plan • PD-LID: Study ADX48621-201 • U.S. & EU Phase II trial in about 140 PD-LID patients • Double-blind, placebo-controlled, two doses of ADX48621 • 6 weeks treatment • Endpoints: multiple instruments (in consultation with KOLs) • Start 4Q2010 • Report data 2H2011 • Dystonia: Study ADX48621-202 • EU Phase IIa trial in about 32 dystonia patients • Double-blind, placebo-controlled, two-way crossover (two dose groups) • 2 week treatment period • Endpoints: multiple instruments (in consultation with KOLs) • Start 4Q2010 • Report data 2H2011
ADX48621Commercial Potential • Levodopa induced dyskinesia (LID) and dystonia are an unmet medical needs • 40% of Parkinson’s disease (PD) develop LID • no drugs specifically approved for PD-LID • growing unmet medical need • PD-LID/dystonia is a faster path to market than PD • Addex can retain co-promotion rights • treated by specialists • geographic split possible • mGluR4 PAM & mGluR2 NAM represent potential additions to future neurodegenerative disease franchise

Allosteric Modulator Discovery & Optimization
Serendipity has yielded some marketed allosteric modulators. Most recent examples include: Sensipar/Mimpra cinacalcet (Amgen) Positive allosteric modulator (PAM) of calcium sensing receptor Approved 2004 treats secondary hyperparathyroidism Selzentry/Celsentri maraviroc (Pfizer) Negative allosteric modulator (NAM) of CCR5 Approved 2007 Treats CCR5-tropic HIV-1 But these molecules are hard to find! Traditional discovery tools are not appropriate. Allosteric Modulators 101
Because they bind a different site on the receptor, allosteric modulators do not turn receptors on or off the way the body’s natural activators and most drugs do. Instead, they act more like a dimmer switch, offering control over the ease & intensity of (de-)activation while allowing the body to retain its natural control over initiating receptor activation via the active site (e.g. the on/off switch). Allosteric Modulation
Orthosterics are steady state Biological response Natural ligand PAM + natural ligand Agonist Time NAM + natural ligand Antagonist Allostery preserves natural rhythm Natural ligand Biological response Time Allosteric Advantages • Greater specificity than orthosteric molecules – e.g. mGluRs • Can target receptors considered “intractable” or only tractable by biologics, peptides or proteins • e.g. GLP-1 • Non-competitive mechanism • Un-exploited intellectual property • Less dose related toxicity • Acts like a dimmer not “on/off” switch • Body maintains control of receptor activation cycle
The Addex raison d'être • Allosteric modulators are hard to find • Industrial tools for orthosteric drugs are not appropriate • Pharma has been focused on tools for finding orthosteric drugs • Why didn’t pharma industrialize allosteric drug discovery? • Upfront investment to build allosteric drug discovery platform was high • Time to value creation was long & uncertain • Addex is industrializing allosteric modulation discovery • Proprietary assays • High throughput screening & optimization tools (compatible with 384 well plates & robotics) • Direct detection systems • proximal to target • continuous real-time observation • works for molecules (i.e. allosteric modulators) that do not activate target receptor • Allostery biased library of over 70,000 compounds
Proprietary Screening AssaysG-Protein Coupled Receptors • Phoenyx • a cAMP dynamic non stop assay • FBBA (GLP1R, mGluR7) • Fluorescence-Based Binding Assay • Measures bi-molecular interactions • Proxylite (GLP1R, GIP) • Proximal & dynamic assays for functional measurements of all types of GPCRs
Proprietary Screening Assaystype 1 single-pass transmembrane proteins • APRA (TNFR1) • Accessory Protein Relocalization Assays • ADX-tags series 1 (IL1R) • Proximal & dynamic assays for functional measurements • Measures activation-dependent association or dissociation of binding partners • ADX-tags series 2 (TNFR1, IL1R) • measures conformational changes that lead to activation signal • measures multimerization changes that lead to activation signal
