Background § ANAVEX®2-73 is a new targeted therapy in Alzheimer and other neurological diseases
§ 57-week Phase 2a study: ANAVEX®2-73 was tested in a 57-week Phase 2a study (AV2-73-0021) with 32 mild-to-moderate Alzheimer’s disease demenBa paBents. This study showed:
− ConcentraBon-dependent response in this populaBon for exploratory funcBonal (ADCS-ADL2) and cogniBve (MMSE3) endpoints
− New AD paBent selecBon genomic biomarker variants of • SIGMAR1 (rs1800866) • COMT (rs113895332/ rs61143203)
− These new paBent selecBon biomarkers enable a targeted therapy for paBents which are likely to benefit from ANAVEX®2-73
§ 57-week Phase 2a study was extended by 208 weeks (AV2-73-0034) in 21 paBents
§ Update at 148-week of Phase 2a extension: The impact of these SIGMAR1 and COMT biomarkers on ANAVEX®2-73 response has been assessed at 148-week extension

Remarks regarding the ANAVEX®2-73-002/003 Studies
§ Data rich study (scores, PK, DNA, RNA) provides a unique opportunity to characterize response
§ CombinaBon of data rich study and KEM® unbiased systemaBc analysis enables idenBficaBon of biomarker hypothesis in a small paBent populaBon
§ Longitudinal study provides confirmaBon of biomarker effect idenBfied at week 57 at week 148
§ IdenBfied biomarker is consistent with a structural raBonale for the mechanism of acBon of ANAVEX®2-73 against its confirmed target SIGMAR1. The consistency of the DNA and RNA findings, as well as the longitudinal effect provides addiBonal strength to the iniBal biomarker-based hypothesis
19
Conclusions & PerspecBve § The longitudinal 148-week data show that paBent cohort with the higher concentraBon of ANAVEX®2-73 maintains
the ADCS-ADL score and becer perform at MMSE, along the trial duraBon, when compared to the lower concentraBon cohort
§ A significant impact of SIGMAR1 and COMT biomarkers on the drug response level was confirmed over the 148-week period, irrespecBve of the fact that APOE ε4 carriers were more frequent in the higher concentraBon cohort
§ The hypothesis that ANAVEX®2-73 induces an improved clinical outcome with adequate effect size holds
§ Results demonstrate robustness by using both DNA- and RNA-based biomarkers, mulBple endpoints and Bme points. Excluding the paBents with the two idenBfied biomarker variants (approximately 20% of the populaBon), the resulBng 80% of the enrolled populaBon would lead to further clinically significant improved funcBonal and cogniBve scores
§ The combinaBon of KEM® FCA and MMRM-LME data analysis methodologies shows the innovaBve ability to idenBfy early biomarkers in clinical trials with small size-populaBon recruited
§ This study supports the study design of the iniBated ANAVEX®2-73 studies in several indicaBons underway, including a Phase 2b/3 study in 450 paBents with early Alzheimer’s disease
§ This approach may expand the access to Precision Medicine and Precision Pharmacology for a wide range of neurodegeneraBve diseases
