ADX48621
• mGluR5 NAM with NCE patents filed – Patents valid through 2025 in most territories
– Chemical series unrelated to other mGluR5 NAM
– Unique metabolic profile
– Unrelated backup series in clinical candidate selection
• Phase I completed– Three studies: SAD, MAD, gender & food effects
– 110 patients treated to date, including older volunteers
– Safety & tolerability justify further clinical study
9
PD-LID & mGluR5• Strong rationale for mGluR5 in PD and PD-LID
– Inhibition of mGluR5 effective in humans* and in animal models of PD & PD-LID
– Loss of dopamine producing cells leads to excess glutamatergic stimulation
– Inhibition of mGluR5 has been shown to reduce glutamatergic stimulation
– Occurrence of LID is associated with a significant up-regulation of mGluR5 binding in the striatum and globus pallidus of Parkinsonian monkeys and humans
• Parkinson’s disease (PD) is growing with the aging population– 3.2 million PD patients in 2020 in EU, U.S. & Japan
160 million people over 65 in the 7 major markets by 2020, OECD estimates Incidence of PD is 2% in people over 65
• Levodopa induced dyskinesia (LID) is an unmet medical need – 40% of Parkinson’s disease (PD) develop LID
– Unmet medical need
– Faster path to market than PD
– Pricing advantage

ADX48621 efficacy in HIC model
• Haloperidol induced catalepsy (HIC) is a model of PDADX48621 dose-dependently reversed HIC in 3 independent experimentsThis effect was comparable to MTEP (well-known to work in these models)
• ADX48621 effects in HIC suggest that itshould be tested further as a potential drug for PD has potential to be a dopamine sparing agent

ADX48621 non-human primate data
• Macaque monkeys rendered Parkinsonian by repeated daily injections of MPTP • Animals received levodopa until the development of dyskinesia
– Levodopa administered twice daily– Dyskinesia severity comparable to humans (score of 10 = completely disabled)
• Animals were treated 30 min prior to levodopa– ADX48621 (3, 10 or 30 mg/kg in water) – Vehicle
• Behavioral assessment began at levodopa administration (first 10 min every 30 min)– trained observers– video review

Chorea = involuntary movements
ADX48621 dose dependently reduced levodopa-induced chorea and dystonia.
The highest dose virtually abolished both chorea and dystonia in the majority of the animals.
13
Developing ADX48621for PD-LID
• ADX48621 to start in 4Q10 Phase IIb dose-range finding study– 150-200 patients / 12 weeks dosing
– Multiple instruments for measuring LID (in consultation with KOLs)
– Data late 2011/early 2012
• NDA / MAA filing as early as 2016
14
Marketing ADX48621for PD-LID
• PD marketing – Specialty neurology sales force (120 reps in US)– 1st-line symptomatic treatment is competitive
• manly marketed dopaminergic drugs• non-dopaminergic drugs will have an advantage
– Growth sustained by ageing population (+2%/year)
• PD-LID is the short-term opportunity for growth in PD– Immature market, awareness has to be raised in patients
• Physicians (but not patients) are educated about the cause of the disorder• Poorly addressed - no approved drugs for dyskinesia• Limited number of investigational drugs likely to capture big market share
– Fast uptake likely • debilitating symptoms• high unmet need• no therapy switch
15
ADX71943
• ADX71943 is a GABAB PAM in preclinical development– Allosteric mechanism may avoid dose dependent
CNS side effects (somnolence/dizziness) seen with orthosteric agonists of GABAB
– Allosteric mechanism may avoid desensitization and open the possibility of oral chronic use thus allowing potential to treat pain (i.e. osteoarthritis)
• ADX71943 is available for partnering
16
ADX71943 for chronic pain
• Main focus on chronic pain– Osteoarthritis pain
– Other types of chronic nociceptive pain
• Osteoarthritis is a widespread condition affecting ~90 million patients – mostly the elderly population
– debilitating symptom is chronic pain
• Current chronic treatments (NSAID, opioids) are unsatisfactory– Limited efficacy of both drug classes
– NSAIDs increase risk of serious thrombotic and GI events
– Opioids are associated with GI disturbances, sedation and addiction
– Apart from injectable NGF antagonists, no new drug class has emerged from clinical trials
• A major opportunity for ADX71943– Product profile fits with market needs (orally available, once daily dosing)
– Unmet needs for such a mature market are strong enough to allow a fast uptake of innovative drug, as underlined by the success of Celebrex which hit $3.3bn sales 5 years after launch
17
ADX71943 analgesic-like effects in preclinical models
Analgesic-like effect of ADX71943 in the CFA* model in rats after oral administration
ADX71943 caused a dose-dependent increase in the withdrawal threshold in the CFA induced mechanical hypersensitivity test in rats, with a minimum effective dose of 10 mg/kg p.o.

ADX68692• ADX68692 is an FSH NAM in preclinical development• Potential indications
– Benign prostatic hyperplasia (BPH)– Endometriosis
• ADX68692 is available for partnering
Roles of FSH/LH
Females
• FSH involved in folliculogenesis– maturation of follicles– estrogen production
• LH triggers ovulation, progesterone
Males
• FSH supports spermatogenesis
• LH stimulates testosterone production
19
ADX68692 for BPH
• ADX68692 oral administration of in male rats for 4 weeks
• Statistically significant reduction in testosterone
• Statistically significant reduction in prostate weight
BPH patient population is expected to grow:
• 15+ million men suffer from symptomatic BPH across the 7 major markets
• Market grew 17.5% to $3.7 billion from 2007 to 2008 in the 7 major markets
• Projections indicate 12.9% increase in # of BPH sufferers from 2009 to 2025

ADX68692 for endometriosis
• Oral ADX68692 for 4 weeks was well tolerated in female rats
• It reduced the number of rats in the estrus/proestrus phase (ovulatory phase)
• It increased the number of female rats in the diestrus phase
• Eventually animals were found in persistent diestrus phase
• Estradiol levels were lowered, even in the proestrus phase
• Reduction in estradiol suggests ADX68692 has potential for treatment of endometriosis
• Endometriosis is estrogen dependent

Partnered Programs
22
mGluR2 PAM and J&J
• mGluR2 PAM program partnered with Ortho-McNeil-Janssen, a Johnson & Johnson company, in 2005
• Comprehensive Phase I program started June 2009– J&J responsible development– Industry average for Phase I is 9-10 months– Phase II could start in mid-2010
• mGluR2 activation is clinically validated by Eli Lilly with their mGluR2/3 agonist– Positive Phase II POC in anxiety– Positive Phase II POC in schizophrenia
• Schizophrenia is important for J&J (Risperdal)
23
mGluR5 PAM & Merck
• Merck & Co., Inc. licensed ADX63365 and mGluR5 PAM backups in 2008
• mGluR5 PAM have demonstrated efficacy in animal models of schizophrenia
• mGluR5 PAM will be highly differentiated if they address cognitive deficit in schizophrenia clinical testing– Many schizophrenia patients are unable to learn skills or support
themselves– Marketed drugs and most drugs in development can reduce psychosis
BUT have not been shown to improve cognitive function – FDA has recognized that cognitive deficit is an unmet medical need in
schizophrenia
• Merck is responsible for development of ADX63365/backups
24
Progress

Agreement
• Discover and develop metabotropic glutamate receptor 4 (mGluR4) positive allosteric modulators (PAM)
• The deal includes mGluR4 PAM leads already discovered by Addex
• Merck is responsible for preclinical and clinical development
• Addex will sit on oversight committees Terms
• $3 million upfront
• $106.5 million in milestones
– 1st product in multiple indications
• Additional $61 million milestones
– For a 2nd and 3rd product
• Undisclosed royalties
• Option to co-promote in certain EU countries

Allosteric Discovery & Optimization Platform

Unlike orthosteric drugs, allosteric modulators are non-competitive. Therefore, their effects on signal transduction are observed
primarily when endogenous ligands bind the active site.
Allosteric Modulation Explained
NB: Most marketed
drugs are orthosteric.
Endogenous ligands
are natural activators
in the body.orthosteric drugs compete
with endogenous ligands for
the active site on a receptor

27
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.: GLP1
• Non-competitive mechanism– Un-exploited intellectual property– Less dose related toxicity
•Acts like a dimmer not “on/off” switch
