The present invention relates to antibodies and
antigen-binding portions thereof that specifically bind to
insulin-like
growth factor I
receptor (IGF-IR), which is preferably human IGF-IR. The invention also relates to human anti-IGF-IR antibodies, including chimeric, bispecific, derivatized,
single chain antibodies or portions of fusion proteins. The invention also relates to isolated heavy and light chain immunoglobulin molecules derived from anti-IGF-IR antibodies and
nucleic acid molecules encoding such molecules. The present invention also relates to methods of making anti-IGF-IR antibodies, pharmaceutical compositions comprising these antibodies and methods of using the antibodies and compositions thereof for diagnosis and treatment. The invention also provides
gene therapy methods using
nucleic acid molecules encoding the heavy and / or light immunoglobulin molecules that comprise the human anti-IGF-IR antibodies. The invention also relates to
gene therapy methods and transgenic animals comprising
nucleic acid molecules of the present invention.
