EVT 301: Alzheimer's disease
MAO-B inhibitor
Disease modifying potential in Alzheimer's disease
Status: Phase I Phase II due to begin in Q4 2006


EVT 301: Novel potentially disease modifying Alzheimer's treatment
- z Orally active, potent, selective and reversible inhibitor of MAO-B
- z Earlier unpublished Phase III trials by Roche of a first generation MAO-B inhibitor have demonstrated encouraging signs of slowing disease progression
- z EVT 301 is a follow up compound from a chemically distinct series with a superior safety profile

MAO-B inhibition: A potentially disease modifying approach
Theoretical consequence of a slowing of symptom progression


Alzheimer's disease, oxidative stress and monoamine oxidase-B rationale
- z Oxidative stress is a central feature of AD and may contribute to its pathogenesis
- z MAO-B activity is stoichiometrically linked to H2O2 production, a ROS able to cross membranes and produce the highly reactive hydroxyl radical (HO.)

- z MAO-B activity is markedly up-regulated in AD brain
- z Blocking MAO-B activity has been shown to reduce disease progression
02 CNS Pipeline

MAO-B is highly over-expressed in reactive astrocytes around amyloid plaques in AD
[3H]lazabemide radioautography

Resolution of MAO-B enriched clusters in cerebral cortices of AD patients


EVT 301: Preclinical summary
- z Potent (10nM), selective (~1000-fold) and reversible MAO-B inhibitor
- z No known off-target activities
- z Potent in vivo activity
- z Clean toxicity and safety profile
- z Excellent ADME profile
- Metabolised to a large extent in extrahepatic tissue by CYP1A1 and CYP1B1
- zLow liability for drug-drug interactions
- CYP450 isoforms IC50s >50 µM


EVT 301: Clinical programme before in-licensing Healthy volunteers


EVT 301: Evotec's future development programme


EVT 101: Alzheimer's disease
Oral NR2B subtype selective NMDA receptor antagonist
Symptomatic Alzheimer's treatment (Potential for neuropathic pain, Parkinson's disease)
Status: Phase I Phase I due to be completed in 2006

02 CNS Pipeline

Restricted distribution of NR2B subunit containing receptors
- zNR2B subunit has a distribution in brain restricted to areas important in:
- Alzheimer's disease (cortex, hippocampus)
- Parkinson's disease (basal ganglia)
- Pain sensation (dorsal horn, thalamus, cortex)







Memantine has been quick to take up market share
- z Approved in Europe and the US for the treatment of moderate-to-severe AD
- z Memantine has blockbuster potential
- z But: non-selective NMDA antagonist with accompanying side effects

Memantine sales in \$ million

EVT 101: A next generation memantine?
Memantine
- zBlock all NMDA receptors in all brain areas
- zTherapeutic window is small (~2x recommended dose: side effects seen)
- zMaximum efficacy compromised by dose limitations due to side effects
- zHigh doses impair memory and learning processes
EVT 101
zSelective for NR2B-containing NMDA receptors
- zTherapeutic window is expected to be higher (>10x preclinically)
- z Can dose to get maximum efficacy
zHigh doses probably do not impair memory and learning processes

EVT 101: Preclinical profile High potency, selectivity and excellent drug like properties
- z High potency and selectivity
-
1,000-fold for any off-target activities
-
- z Rapidly and extensively absorbed
- z Moderate plasma clearanc e
- z Good brain penetration
- CSF/plasma ratio 0.25 – reflects free plasma concentration
- z High oral potency with low side-effects
- z High in vitro metabolic stability in microsomes and hepatocytes
- z Low potential for drug-drug interaction
- CYP450 isoforms IC50s >50 µM
- z Successfully completed all regulatory toxicology and safety studies required for entry-into-man


EVT 101 Phase I trial: SAD and MAD
zEVT 101 at single oral doses of up to 15 mg was safe and well tolerated
- No serious adverse events recorded
- Most of the adverse events recorded were mild and short-lasting
- No food effect
- There were no clinically significant changes in safety parameters including ECGs, vital signs and blood and urine tests
- Good exposure and PK profile - Tmax ~2h, T-half ~11h, dose proportionality
- z EVT 101 dosed to 4 mg twice daily and 8 mg once daily for eight days in young subjects (24)
- z EVT 101 dosed up to 3 mg twice daily in elderly (20)
- z Systemic exposure exceeds concentrations predicted to be therapeutically active

EVT 101: Development options


EVT 201: Insomnia
GABAAmodulator
Insomnia
Status: Phase I/II Phase II due to begin in Q3 2006


Preclinical profile of EVT 201
- z EVT 201 acts with high affinity at the benzodiazepine site on the GABAA receptor complex, with a Ki value of 0.8 nM in a 3H-flumazenil binding assay and displays high binding specificity versus other known targets
- z In functional assays on cloned GABAA receptor subtypes it acts as a slightly alpha-1 selective, high affinity partial positive modulator
- z Active in anxiety, panic and anticonvulsant tests in rats and mice
- Dose range from 0.01 – 30 mg/kg
- Only slightly less potent than the full agonist alprazolam
- z Adverse effects (impaired rotarod performance, amnesia, convulsions upon withdrawal) were observed after 1 to 10 mg/kg of alprazolam p.o.
- z No adverse effects observed at doses of up to 30 & 100 mg/kg of EVT 201 p.o.
- z EVT 201 did not potentiate sedative effects of ethanol in mice at doses up to 100 mg/kg s.c.
- Alprazolam was already markedly active at 0.3 mg/kg s.c.
- z No development of tolerance to the anxiolytic effect of EVT 201 after 4 weeks of continuous treatment


EVT 201: Completed clinical studies

65 subjects (39 active)
12 subjects
02 CNS Pipeline

EVT 201 design of proof-of-principle study for insomnia : Road traffic noise model in healthy volunteers


EVT 201: Summary results of proof-of-principle study
- zSignificant reduction in latency to persistent sleep
- z Significant reduction in WASO, awakenings and arousals
- z Increased duration of slow wave sleep, no reduction of REM sleep duration
- z Highly significant increase in quality of sleep and strong trends towards ease of awakening in the morning and improvement in early morning behaviour
- z Minimal residual hang over effects on quantitative measures at 8h post-dose time point, all gone by 10h
- z Significantly improved next day alertness and mood
