Abstract
Binding proteins, such as antibodies directed to IGF-II with cross-reactivity to IGF-I and uses of such antibodies are described. In particular, fully human monoclonal antibodies directed to the IGF-II with cross-reactivity to IGF-I are disclosed. Also discussed are nucleotide sequences encoding, and amino acid sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions and/or complementarity determining regions (CDR's), specifically from FR1 through FR4 or CDR1 through CDR3.

A method of treating a malignant tumor in a mammal, comprising:
- selecting a mammal in need of treatment for a malignant tumor;
- and
- administering to said mammal a therapeutically effective dose of a n antibody, or antigen-binding fragment thereof, that preferentially binds to insulin-like growth factor-II (IGF-II) with crossreactivity to insulin-like growth factor I (IGF-I), wherein said antibody comprises a heavy chain variable region comprising the sequence of SEQ ID NO:6 and a light chain variable region.
A method of treating a malignant tumor in a mammal, comprising:
- selecting a mammal need of treatment for a malignant tumor, and
- administering to said mammal a therapeutically effective dose of an antibody, or antigen-binding fragment thereof, that preferentially binds to insulin-like growth factor-II (IGF-II) with cross-reactivity to insulin-like growth factor I (IGF-I), wherein said antibody comprises a light chain variable region comprising the sequence of SEQ ID NO:8 and a heavy chain variable region.
A method of treating a malignant tumor n a mammal, comprising:
- selecting a mammal in need of treatment for a malignant tumor;
- and
- administering to said mammal a therapeutically effective dose of an antibody, or antigen-binding fragment thereof, that preferentially binds to insulin-like growth factor-II (IGF-II) with cross-reactivity to insulin-tike growth factor I (IGF-I), wherein said antibody has the amino acid sequence of the antibody produced by hybridoma cell line 7.159,2 (ATCC Accession Number PTA-7424).
A method of treating a malignant tumor a mammal, comprising:
- selecting a mammal in need of treatment for a malignant tumor;
- and
- administering to said mammal a therapeutically effective dose of an antibody, or antigen-binding fragment thereof, that preferentially binds to insulin-like growth factor-II (IGF-II) with cross-reactivity to insulin-like growth factor I (IGF-I), wherein said antibody comprises:
- heavy chain complementarity determining region 1 (CDR1) comprising the amino acid sequence of “Ser Tyr Asp Ile Asn” (SEQ ID NO:
- 33);
- a heavy chain complementarity determining region 2 (CDR2) comprising the amino acid sequence of “Trp Met Asn Pro Asn Ser Gly Asn Thr Gly Tyr Ala Gln Lys Phe Gln Gly” (SEQ ID NO:
- 34);
- a heavy chain complementarity determining region 3 (CDR3) comprising the amino acid sequence of “Asp Pro Tyr Tyr Tyr Tyr Tyr Gly Met Asp Val” (SEQ ID NO:
- 35);
- a light chain complementarity determining region 1 (CDR1) comprising the amino acid sequence of “Ser Gly Ser Ser Ser Asn Ile Glu Asn Asn His Val Ser” (SEQ ID NO:
- 36);
- a light chain complementarity determining region 2 (CDR2) comprising the amino acid sequence of “Asp Asn Asn Lys Arg Pro Ser” (SEQ ID NO:
- 37);
- and a light chain complementarity determining region 3 (CDR3) comprising the amino acid sequence of “Glu Thr Trp Asp Thr Ser Leu Ser Ala Gly Arg Val” (SEQ ID NO:
- 38).
