Abstract
Methods are provided for treating HPG axis-positive cancers, preventing or slowing proliferation of cells of HPG axis-positive cancer origin, preventing HPG axis-positive cancers in a patient at risk of contracting such cancers, preventing or inhibiting an upregulation of the cell cycle in HPG axis-positive cancer-derived cells in a patient, and decreasing the level of HPG axis-positive cancer-specific markers in a patient.

A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, for preventing an HPG axis-positive cancer in a patient at risk of contracting an HPG axis-positive cancer, for decreasing the level of an HPG axis-positive cancer-specific marker in a patient, or for preventing or slowing proliferation of cells of HPG axis-positive cancer origin in a patient, comprising:
- administering to the patient a therapeutically effective amount of at least one physiological agent that decreases or regulates blood or tissue levels, expression, production, function, or activity of at least one of luteinizing hormone (LH), LH receptors, follicle stimulating hormone (FSH), FSH receptors, an androgenic steroid, androgenic steroid receptors, an activin, and activin receptors.
A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, for preventing an HPG axis-positive cancer in a patient at risk of contracting an HPG axis-positive cancer, for decreasing the level of an HPG axis-positive cancer-specific marker in a patient, or for preventing or slowing proliferation of cells of HPG axis-positive cancer origin in a patient, comprising:
- administering to the patient a therapeutically effective amount of at least one physiological agent that increases or regulates blood or tissue levels, expression, production, function, or activity of at least one of gonadotropin releasing hormone (GnRH), an inhibin, and a follistatin.
A method of preventing or inhibiting an upregulation of the cell cycle in HPG axis-positive cancer-derived cells in a patient, comprising:
- administering to the patient an amount of at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists, effective to reduce local tissue production of hormones of the hypothalamic-pituitary-gonadal (HPG) axis.
A method of treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient an amount of at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists, effective to achieve a blood serum level of about 1.5 ng/ml of the physiological agent for a predetermined time interval.
A method of treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient an amount of at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists, effective to achieve a blood serum level of about 2.0 ng/ml of the physiological agent for a predetermined time interval.
A method of treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient an amount of at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists, effective to achieve a blood serum level of about 2.5 ng/ml of the physiological agent for a predetermined time interval.
A method of treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient an amount of at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists, effective to achieve a blood serum level of about 3.0 ng/ml of the physiological agent for a predetermined time interval.
A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient an initial dose of a GnRH agonist or a GnRH antagonist;
- and
- monitoring for decreases in an HPG axis-positive cancer-specific marker level in the patient, and subsequently administering to the patient increasing doses of the GnRH agonist or the GnRH antagonist until no further decrease in an HPG axis-positive cancer-specific marker level in the patient is observed.
A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient a therapeutically effective amount at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists by substantially continuously infusing the physiological agent directly into an organ or anatomical site of the patient affected by the HPG axis-positive cancer so that HPG axis-positive cancer cells are exposed to concentrations of the physiological agent that would result from blood serum concentrations of the physiological agent of about 1.5 to about 3.0 ng/ml for a pre-determined time interval.
A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient a therapeutically effective amount of at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists, by implanting a pharmaceutical controlled release formulation of the at least one physiological agent directly into or near tissue of the patient affected by the HPG axis-positive cancer.
A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient a therapeutically effective amount of at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists, by infusing a pharmaceutical controlled release formulation of the at least one physiological agent directly into tissue of the patient affected by the HPG axis-positive cancer.
A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient a first physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists in a therapeutically effective combination with a second physiological agent selected from the group consisting of androgen synthesis blockers, analogues of androgen synthesis blockers, FSH receptor blockers, analogues of FSH receptor blockers, testosterone, testosterone analogues, LH receptor blockers, analogues of LH receptor blockers, activin blockers, and analogues of activin blockers.
A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient having the HPG axis-positive cancer a physiological agent that decreases the degradation of GnRH agonists or GnRH antagonists within the patient, increases the half-life of GnRH agonists or GnRH antagonists within the patient, or increases tissue levels of GnRH agonists or GnRH antagonists within the patient.
A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient having the HPG axis-positive cancer an amount of at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists, effective to achieve a blood serum level of between about 1.5 and about 3.0 ng/ml of the physiological agent for a predetermined time interval in combination with administering to the patient a standard chemotherapeutic agent as indicated for the HPG axis-positive cancer.
A method for treating an HPG axis-positive cancer in a patient having an HPG axis-positive cancer, comprising:
- administering to the patient having the HPG axis-positive cancer an amount of at least one physiological agent selected from the group consisting of GnRH agonists and GnRH antagonists, effective to achieve a blood serum level of between about 1.5 and about 3.0 ng/ml of the physiological agent for a predetermined time interval in combination with administering to the patient a standard radiation treatment regimen as indicated for the HPG axis-positive cancer.
