## Abstract

The invention provides an antibody comprising human IgG1 or IgG3 heavy chain constant domains that are glycosylated with a sugar chain at Asn297, said antibody being characterized in that the amount of fucose within said sugar chain is at least 99%, and in addition the amount of NGNA is 1% or less and/or the amount of N-terminal alpha 1,3 galactose is 1% or less, and uses thereof.

## Claims

### Claim 1

A monoclonal antibody of IgG1 or IgG3 type glycosylated at Asn297, said antibody comprising an antibody wherein the sugar chain of said antibody comprises at least 99.4% fructose as analyzed by Liquid Chromatography Mass Spectronety (LCM) peptide map analysis and wherein the amount of fructose within said sugar chain related to the sum of G0, G1, G2 without mannose 4 and mannose 5 is 100%; and, the amount of N-glycolylneuraminic acid is 1% or less of the sugar chain as related to the sum of G0, G1, G2 without mannose 4 and mannose 5 as analyzed by LCMS and the N-terminal alpha-1,3-galactose, is 1% or less of the sugar chain.

### Claim 2 (depends on 1)

The antibody according to claim 1, wherein the amount of N-glycolylneuraminic acid is 0.5% or less of the sugar chain.

### Claim 3 (depends on 1)

The antibody according to claim 1, wherein the amount of N-terminal alpha-1,3-galactose is 0.5% or less of the sugar chain.

### Claim 4 (depends on 1)

The antibody according to claim 1, wherein the antibody is a chimeric, humanized or human antibody.

### Claim 5 (depends on 1)

The antibody according to claim 1, wherein the antibody shows one or more properties selected from the group consisting of:
a) shows a ratio of IC50 values of inhibition of the binding of IGF-I to IGF-IR to the inhibition of binding of insulin-like growth factor II (IGF-II) to IGF-IR of 1:3 to 3:1,
b) inhibits, at a concentration of 5 nM, at least 80% of the IGF-IR phosphorylation in a cellular phosphorylation assay using HT29 cells in a medium containing 0.5% heat-inactivated fetal calf serum when compared to such an assay without said antibody,
c) shows no IGF-IR stimulating activity measured as PKB phosphorylation at a concentration of 10 μM in a cellular phosphorylation assay using 3T3 cells providing 400,000 to 600,000 molecules IGF-IR per cell in a medium containing 0.5% heat-inactivated fetal calf serum (FCS) when compared to such an assay without said antibody.

### Claim 6 (depends on 1)

The antibody according to claim 1, wherein the antibody has an affinity of about 10−13 to 10−9 M (KD) for IGF-IR.

### Claim 7 (depends on 1)

The antibody according to claim 1 produced by the CHO cell line hu MAb<IGF-1R>B1-4E10—9-16 deposited with the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, Germany, under Accession No. DSM ACC 2795.

### Claim 8 (depends on 1)

A pharmaceutical composition comprising an antibody according to claim 1 and a pharmaceutically acceptable carrier or excipient.

### Claim 9 (depends on 7)

A pharmaceutical composition comprising an antibody according to claim 7 and a pharmaceutically acceptable carrier or excipient.

### Claim 10 (depends on 1)

A CHO cell that recombinantly expresses an antibody that when purified is an antibody according to claim 1.

### Claim 11 (depends on 7)

A CHO cell that recombinantly expresses an antibody that when purified is an antibody according to claim 7.

### Claim 12

A CHO cell hu MAb<IGF-1R>B1-4E10—9-16 deposited with the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, Germany, under Accession No. DSM ACC 2795.
