The present invention relates to a method of treating prostate cancer with androgen deprivation therapy and an insulin-like growth factor receptor (IGF-IR) antagonist. Although the response rate of prostate cancer to androgen deprivation therapy (ADT) is high, surviving cancer cells invariably become androgen independent (AI) and tumor growth follows. The invention inhibits or delays transition of androgen dependent cancer to androgen independent cancer, significantly decreases risk of recurrence, and improves treatment outcome.

The present invention includes fully human, neutralizing, monoclonal antibodies against human Insulin-like Growth Factor Receptor-I (IGFR1). The antibodies are useful for treating or preventing cancer in a subject. Also included are methods of using and producing the antibodies of the invention.

An antibody binding to IGF-IR, being of human IgG1 or IgG3 type and being glycosylated with a sugar chain at Asn297, said antibody being characterized in that the amount of fucose within said sugar chain is at least 98%, 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 has improved properties in antitumor therapy.

Disclosed herein are isolated monoclonal human antibodies that specifically binds insulin-like growth factor II (IGF-II) with an equilibrium dissociation constant (K_d) of 1 nM or less, wherein the antibody bind IGF-I with an equilibrium dissociation constant (K_d) of 1 mM or greater. The antibodies inhibit phosphorylation of the insulin-like growth factor receptor. Nucleic acids encoding these antibodies, expression vectors including these nucleic acids, and isolated host cells that express the nucleic acids are also disclosed. The antibodies can be used to detect human IGF-II in a sample. Methods of diagnosing a tumor are disclosed herein that utilize these antibodies. Methods of treating a subject with a tumor are also disclosed.

The present invention provides compositions and methods for modulating the expression of growth factor gene. In particular, this invention relates to compounds, particularly oligonucleotide compounds, which, in preferred embodiments, hybridize with nucleic acid molecules encoding the Insulin Like Growth Factor I receptor (IGF-I receptor or IGF-IR) and in particular human IGF-IR. Such compounds are exemplified herein to modulate proliferation which is relevant to the treatment of proliferative and inflammatory skin disorders and cancer. It will be understood, however, that the compounds can be used for any other condition in which the IGF-IR is involved including inflammatory conditions.

The present invention includes fully human, neutralizing, monoclonal antibodies against human Insulin-like Growth Factor Receptor-I (IGFR1). The antibodies are useful for treating or preventing cancer in a subject. Also included are methods of using and producing the antibodies of the invention.

The invention discloses a pyrrolidine[3,4-d]pyrimidine derivative and a preparation method and an application thereof. The pyrrolidine[3,4-d]pyrimidine derivative is an inhibitor of a type I insulin-like growth factor receptor (IGF-1R), and has a good IGF-1R inhibiting function and a good cancer cell proliferation inhibiting function, so that the pyrrolidine[3,4-d]pyrimidine derivative can be taken as a therapeutic agent for treating tumors and relevant diseases.

The present disclosure relates to compositions and methods for treating cancers using antisense (AS) nucleic acids directed against Insulin-like Growth Factor 1 Receptor (IGF-1R). The AS may be administered to the patients systemically, or may be used to produce an autologous cancer cell vaccine.
