Enclosed is a translation of the patent claims in Norwegian. Please note that as per the Norwegian Patents Acts, section 66i the patent will receive protection in Norway only as far as there is agreement between the translation and the language of the application/patent granted at the EPO. In matters concerning the validity of the patent, language of the application/patent granted at the EPO will be used as the basis for the decision. The patent documents published by the EPO are available through Espacenet (http://worldwide.espacenet.com) or via the search engine on our website here: https://search.patentstyret.no/ NO/EP2451844

1 Patentkrav EP2451844 5 10 15 1. Et monoklonalt antistoff som spesifikt binder et humant TLR3-polypeptid, karakterisert ved at nevnte antistoff hemmer signalering ved TLR3-polypeptidet uten å blokkere binding av en dsrna TLR3-ligand til TLR3-polypeptidet, hvor nevnte antistoff som spesifikt bindes til TLR3-polypeptidet under nøytrale betingelser ved en ph mellom 6,6 og 7,4 og under sure betingelser ved en ph på mellom 4,5 og 6,5 med en sub-nanomolar K D for sin bivalente bindingsaffinitet; hvor nevnte antistoff konkurrerer for binding til et TLR3-polypeptid med et antistoff valgt fra gruppen bestående av: (a) et antistoff som har henholdsvis en VH- og VL-region i SEQ ID NO 34 og 35, og (b) et antistoff som har henholdsvis en VH- og VL-region i SEQ ID NO 2 og 3. 20 25 30 2. Antistoff ifølge krav 1, hvor nevnte antistoff binder spesifikt til TLR3-polypeptidet under sure betingelser med en 100 picomolar eller bedre K D for sin bivalente bindingsaffinitet. 3. Antistoffet ifølge krav 1-2, hvor antistoffet er valgt fra gruppen bestående av: (a) et antistoff som har (i) tungkjede-cdr 1, 2 og 3 (HCDR1, HCDR2, HCDR3) aminosyresekvenser som vist i henholdsvis SEQ ID NO: 4, 5 og 6, og (ii) lettkjede- CDR 1,2 og 3 (LCDR1, LCDR2, LCDR3) aminosyresekvenser som vist i henholdsvis SEQ ID NO: 7, 8 og 9; og (b) et antistoff som har (i) tungkjede-cdr 1, 2 og 3 (HCDR1, HCDR2, HCDR3) aminosyresekvenser som vist i tungkjede-cdr SEQ ID NO: 36, 37 og 38, og (ii) lettkjede-cdr 1, 2 og 3 (LCDR1, LCDR2, LCDR3) aminosyresekvenser som vist i tungkjede-cdr SEQ ID NO: 39, 40 og 41. 4. Antistoff ifølge kravene 1 til 3, hvor antistoffet er et kimært, humant eller humanisert antistoff. 35 5. Antistoff ifølge krav 4, hvor isotypen av nevnte antistoff er et IgG4. 6. Antistoff ifølge kravene 1 til 5, hvor antistoffet omfatter en Fc-region som er modifisert for å redusere dens FcγR-binding.

2 7. Antistoff ifølge kravene 1 til 6, hvor nevnte antistoff er et antistoff-fragment valgt fra Fab, Fab', Fab'-SH, F (ab') 2, Fv, diastoffer, enkelt-kjede antistoff-fragment, eller et multispesifikt antistoff som omfatter multiple forskjellige antistoff-fragmenter. 5 10 15 20 25 30 8. Antistoff ifølge kravene 1 til 7, hvor nevnte antistoff er konjugert eller kovalent bundet til en toksisk del. 9. Antistoff ifølge kravene 1 til 8, hvor nevnte antistoff er i stand til å internaliseres ved hjelp av en TLR3-uttrykkende celle. 10. Antistoff ifølge kravene 1 til 9, hvor nevnte antistoff er konjugert eller kovalent bundet til en påvisbar del. 11. Antistoff ifølge kravene 1 til 10, hvor nevnte antistoff produseres ved immunisering av et ikke-humant dyr med et immunogen som omfatter et TLR3- polypeptid. 12. Hybridom eller rekombinant vertscelle som produserer antistoffet ifølge kravene 1 til 11. 13. Farmasøytisk sammensetning som omfatter et antistoff ifølge hvilket som helst av kravene 1-11, og en farmasøytisk akseptabel bærer. 14. Farmasøytisk preparat ifølge krav 13, for anvendelse ved behandling eller forebygging av en sykdom valgt fra gruppen som består av autoimmunitet, betennelse, allergi, astma, infeksjon, cirrhose og sepsis. 15. Farmasøytisk sammensetning ifølge krav 13, for anvendelse ved behandling eller forebygging av kreft.
