The invention provides a novel prostate cell-surface antigen, designated Prostate Stem Cell Antigen (PSCA), which is widely over-expressed across all stages of prostate cancer, including high grade prostatic intraepithelial neoplasia (PIN), androgen-dependent and androgen-independent prostate tumors.

Compounds having the structure or their salts:

are used to treat or reduce le likelihood of acquiring androgen-dependent diseases, such as prostate cancer, benign prostatic hyperplasia, polycystic ovarian syndrome, acne, hirsutism, seborrhea, androgenic alopecia and male baldness. They can be formulated together with pharmaceutically acceptable diluent or carrier or otherwise made into any pharmaceutical dosage form. Some of these compounds having tissue-specific antiandrogenic activity and tissue-specific androgenic activity can be used to treat or reduce the risk of developing diseases related to loss of androgenic stimulation. Combinations with other active pharmaceutical agents are also disclosed.

Bimatoprost, a prostamide F2 alpha analog, used alone or in combination with other prostamides, or prostaglandin analogs, in a topical manner for the promotion of hair growth in mustache, beard, chest and other androgen dependent hair growth areas in humans and animals.

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 invention provides an immunogenic composition comprising a GnRH multimer and an antigenic carrier, an immunogenic composition comprising a recombinant vector containing a nucleic acid molecule encoding a GnRH multimer and optionally an antigenic carrier, antibodies elicited by the immunogenic compositions, and methods of using the immunogenic compositions and antibodies for modifying sexual physiology and behavior, improving the organoleptic properties of meat, and treating androgen-dependent prostate tumors and GnRH-sensitive ovarian tumors.

The present invention provides synthetic ribozyme oligonucleotides alone and within constructs. The ribozyme gene provides methods for the treatment of prostate hyperplasia and other androgen dependent pathologies. Improved therapies for such diseases are provided without significant hormonal imbalance and without surgical intervention. Also provided are techniques for selecting and synthesizing effective and specifically targeted molecular tools for use in inhibiting androgen receptor gene expression.

A treatment for cancer using a combination therapy including an inhibitor of the PI3K/Akt pathway in combination with roscovitine. It is shown that the combination of roscovitine and API-2 (Triciribine) or roscovitine and LY294002 induce the apoptosis of androgen-dependent (LNCaP) and androgen-independent (PC3) prostate cancer cells. Two important results have been observed. First, cells that respond to roscovitine alone (LNCaP) initiate apoptosis sooner when co-treated. Second, cells that do not respond to roscovitine alone (PC3) apoptose when co-treated, although with delayed kinetics. In the absence of roscovitine, AKT inhibitors had no effect on LNCaP or PC3 survival, and in both cell lines, the combined treatment activated the mitochondrial pathway of apoptosis. Importantly, normal epithelial cells (RPWE) remained viable in the presence of roscovitine and AKT inhibitors. Events elicited by roscovitine (down-regulation of XIAP) and AKT inhibitors (accumulation of Bim) in LNCaP and PC3 cells are identified. Additional data show that PC3 cells apoptose when treated with AKT inhibitors and depleted of either XIAP or Cdk9. Taken together, these important results lead to improved treatments for cancers, such as prostate cancer, through the combination therapies taught herein.

Androgen nucleus derivatives having specified substituents at the 17 alpha position are disclosed for use as antiandrogens for the treatment of androgen-dependent diseases. In some preferred embodiments, the compound is formulated together with pharmaceutically acceptable diluent or carrier for topical use in the treatment of androgen-dependent diseases associated with the skin.

Biphenyl derivatives are disclosed for use in the treatment of androgen-dependent diseases such as prostate cancer, benign prostatic hyperplasia, precicious puberty, polycystic ovarian syndrome, acne, hirsutism, seborrhea, androgenic alopecia and premature male baldness. For example, some preferred compounds having the structure: are formulated together with pharmaceutically acceptable diluent or carrier for topical use in the treatment of androgen-dependent prostate cancer.

This invention provides a novel class of androgen receptor targeting agents (ARTA). The agents define a new subclass of compounds which are tissue-selective androgen receptor modulators (SARM), which are useful for oral testosterone replacement therapy, male contraception, maintaining sexual desire in women, treating prostate cancer and imaging prostate cancer. These agents have an unexpected in-vivo activity for an androgenic and anabolic activity of a nonsteroidal ligand for the androgen receptor. These agents may be active alone or in combination with progestins or estrogens. The invention further provides a novel class of nonsteroidal agonist compounds and methods of binding an androgen receptor, modulating spermatogenesis, treating and imaging prostate cancer, and providing hormonal therapy for androgen-dependent conditions.

The invention provides a transgenic mouse and cell lines with a homozygous disruption of a chromosomal PTEN gene in prostate cells. The mouse progresses from hyperplasia to metastatic cancer and can be used to identify prostate cancer therapeutics and genes that are differentially regulated during androgen dependent and androgen independent prostate cancer progression.

Disclosed herein are methods and compositions for the treatment of prostate cancer with an IGF-1 receptor kinase inhibitor. Methods are also provided for the treatment of prostate cancer by identifying a level of IGF-1 receptor expression and making a decision whether to treat with an IGF-1 receptor kinase inhibitor.

Compounds having the structure or their salts:

are used to treat or reduce the likelihood of acquiring androgen-dependent diseases, such as prostate cancer, benign prostatic hyperplasia, polycystic ovarian syndrome, acne, hirsutism, seborrhea, androgenic alopecia, male baldness, muscle atrophy and weakness, sarcopenia, male hypogonadism, erectile dysfunction, female sexual dysfunction and osteoporosis. They can be formulated together with pharmaceutically acceptable diluent or carrier or otherwise made into any pharmaceutical dosage form. Combinations with other active pharmaceutical agents are also disclosed.
