Allergy is a Global Public Health Issue
 Considerable Medical Need and Market Opportunity
> 500 million patients
A global pharmaceutical market over € 10 billion/year
Fastest growing chronic condition affecting up to 25-30% of the population
Allergy Immunotherapy (AIT) is the only long term cure for allergies
AIT sales: 1 billion € (+ 8% / year)
AIT use has been limited by
treatment duration :
poor compliance :
use of crude extracts :

AIT with Contiguous Overlapping Peptides
“COP Allergy Vaccines”
Allergen
COP-1
ANERGIS IP
COP-2
COP-3
--------------------------
 Long synthetic peptides (40-80 aa)
 Containing the complete allergen sequence with terminal overlaps
 No detectable binding to IgEs from allergic patients
 AIT with COPs in lieu of conventional extracts or allergens
AIT: Allergy immunotherapy ; COP: Contiguous Overlapping Peptides ; aa: amino acid ; IP: intellectual property ; IgE : Immunoglobulin G type E

Advantages of COP Allergy Vaccines
No conformational
epitopes (no IgE binding)
Safe at high dose
Safety, allowing increased dosing
Much Shorter Treatment
Full allergen sequence
Optimal B and T cell responses
COP presentation
similar to allergens
Efficacy comparable to conventional AIT
Synthetic GMP peptides
Two-level patent
protection

Clinical Proof-of-Concept Trial
AllerT (birch)
 Pre-Phase I/IIa: absence of detectable IgE binding
 in vitro with sera from allergic patients and in a sensitized mice model
 No reactions to skin prick tests in allergic patients (clinical trial AN002T)
 Clinical Phase I/IIa in allergic patients (AN003T)
 Double-blind, randomized AllerT (15) vs placebo (5)
 Subcutaneous injections on days 1, 7, 14, 21 and 51
 Cumulative dose ~3 years of conventional SCIT

Demonstrated Long Term Immune Memory
AllerT (birch)
Allergen-Specific IgG4 Antibodies after 2nd and 4th Seasons in the Phase 1 Patients
Data (median) from blood samples collected in July 2012 from subjects allergic to birch pollen who had received 5 SC injections over 2 months of placebo or AllerT in trial AN003.
All within group changes from baseline for placebo are NS. Placebo N=5, AllerT N=15.

Clinical Phase IIb Trial Conclusions
 AllerT is efficacious
 In a seasonal trial with natural allergen exposure
 Improvements in primary and secondary endpoints are clinically meaningful
 Improvements are similar to marketed 3-year AIT products
 AllerT is safe and well tolerated
 No anaphylactic shock or grade 3 immediate (< 30 min) systemic reaction
 AllerT 50 µg is as efficacious as AllerT 100 µg
