2. FIT Biotech Ltd. Private Company, founded in 1995 Based in Tampere, Finland cGMP manufacturing facility GTU ® - Gene Transport Unit - Proprietary vector platform technology Solid IP covering GTU ® globally 2

3. Novel DNA plasmid based GTU ® Vector Properties Safe –Non-replicating, non-integrating DNA plasmid –Multiple injections possible Effective –Episomal anchoring and segregation-partitioning enhancement –Higher # cells transfected, and high expression level of gene of interest Solid IP position

4. GTU Enhances Expression in Muscle and Skin In Vivo 4

5. Preclinical Studies with GTU ® Vectors Expression studies –Superior expression of antigen in GTU versus conventional vectors - comparative data from mice, swine and non-human primates –Lower amount of DNA needed Preclinical immunogenicity studies in non-human primates (Martinon et.al., 2009, Human Gene Therapy) 5

6. Primate Data: Antigen Expression in Draining Lymph Nodes MultiHIV i.d. + EP p24CD1a p24 + CD1a Day 8 post injection Macaque study published 2009 in Human Gene Therapy Plasmid delivered intradermally into keratinocytes Found antigen in draining lymph nodes This is evidence of cross- presentation 6

7. Conclusions from NHP Studies AuxoGTU ® -MultiHIV B plasmid induces strong anti-HIV cell-mediated immune response Induces polyfunctional (IFNg + IL-2) T-cells Induces long lasting HIV specific T-cells (> 3 years) The response is strongly dependent on the delivery method 77

8. Therapeutic HIV Vaccine for Functional Cure Immunological support for HIV infected individuals –Lowers plasma viral load Reduces sexual and mother-to-child transmission –Restores functional CD4 cells Delays development of AIDS Early therapeutic intervention in HIV infected individuals –Reduces side effects caused by ART –Reduces drug induced resistant mutations 8

9. 9 GTU ® MultiHIV Vaccine: Six Target Genes A fusion protein representing 6 different HIV-1 genes The antigen sequences are derived either from the specific isolate or are deduced from the HIV1 consensus (A, B, C) and phylogenetic ancester (FGH) sequences Maximal representation by in tandem arrayed epitope-rich regions Codon optimization for maximal expression and inclusion of immuno-stimulatory sequences Preclinical studies - mice,swine, NHP
