  • About 1 man in 7 will be diagnosed with prostate cancer during his lifetime.
  • Prostate cancer develops mainly in older men.
  • About 6 cases in 10 are diagnosed in men aged 65 or older, and it is rare before age 40.
  • Prostate cancer is the third leading cause of cancer death in American men, behind lung cancer and colorectal cancer.
  • About 1 man in 39 will die of prostate cancer.
  • prostate cancers are slow growing; however, there are cases of aggressive prostate cancers.
  • the cancer cells may metastasize (spread) from the prostate tu ulher parts of the body, particularly the bones and lymph nodes.
  • Prostate cancer may cause pain, difficulty in urinating, problems during sexual intercourse, or erectile dysfunction. Other symptoms can potentially develop during later stages of the disease.
  • Treatment options for prostate cancer with intent to cure are primarily surgery, radiation therapy, and proton therapy.
  • Other treatments such as hormonal therapy, chemotherapy, cryosurgery, and high intensity focused ultrasound (HIFU) also exist, depending on the clinical scenario and desired outcome.
  • HIFU high intensity focused ultrasound
  • Enzalutamide is an orally bioavailable, organic, non-steroidal small molecule targeting the androgen receptor (AR) with potential antineoplastic activity. Through a mechanism that is reported to be different from other approved AR antagonists, enzalutamide inhibits the activity of prostate cancer cell ARs, which may result in a reduction in prostate cancer cell proliferation and, correspondingly, a reduction in the serum prostate specific antigen (PSA) level. AR over- expression in prostate cancer represents a key mechanism associated with prostate cancer hormone resistance
  • Enzalutamide is marketed by Astellas Pharma Inc. with the brand name XTANDI ® . It is recommended in combination with a luteinizing hormone-releasing hormone analog or surgical castration.

  • Prostate cancer is a complex disease.
  • a number of biological pathways have been implicated in prostate cancer development: growth factor activity, cell death (apoptosis), oncogenesis, tumor suppression, cell cycle modulation, cell surface modulation, androgen receptors, co-activators & repressors.
  • Several conditions are associated with prostate disease: Benign prostate hyperplasia (BPH), prostatitis, prostatic intraepithelial neoplasia (PIN).
  • Benign prostatic hyperplasia refers to the increase in size of the prostate in middle-aged and elderly men. BPH is characterized by hyperplasia of prostatic stromal and epithelial cells, resulting in the formation of large, fairly discrete nodules in the periurethral region of the prostate. Although prostate specific antigen levels may be elevated in these patients, because of increased organ volume and inflammation due to urinary tract infections, BPH is not considered to be a premalignant lesion.
  • Alpha blockers (a 1 -adrenergic receptor antagonists) provide symptomatic relief of BPH symptoms.
  • 5a-reductase inhibitors When 5a-reductase inhibitors are used together with alpha blockers a reduction of BPH progression to acute urinary retention and surgery has been noted in patients with enlarged prostates.
  • Prostate cancer is classified as an adenocarcinoma, or glandular cancer, that begins when normal semen-secreting prostate gland cells mutate into cancer cells. Initially, small clumps of cancer cells remain confined to otherwise normal prostate glands, a condition known as carcinoma in situ or prostatic intraepithelial neoplasia (PIN). Although there is no clear evidence that ⁇ is a cancer precursor, it is closely associated with cancer.
  • Prostate specific antigen is a 34 kD glycoprotein manufactured almost exclusively by the prostate gland. Also known as kallikrein III, PSA is a serine protease. (Lilja H. (Nov 2003). "Biology of Prostate-Specific Antigen”. Urology 62 ((5 Suppl 1)): 27-33).
  • PSA is often elevated in the presence of prostate cancer and in other non-malignant prostate disorders such as BPH.
  • a blood test to measure PSA is the most effective test currently available for the early detection of prostate cancer.
  • Higher than normal levels of PSA are associated with both localized and metastatic prostate cancer (CaP).
  • CaP metastatic prostate cancer
  • PSA levels can change for many reasons other than cancer. Two common causes of high PSA levels in the absence of cancer are enlargement of the prostate (benign prostatic hypertrophy (BPH)) and infection in the prostate (prostatitis).
  • PSA is not a perfect test. Some men with prostate cancer do not have an elevated PSA, and most men with an elevated PSA do not have prostate cancer. Short of biopsy, no noninvasive tests provide a clear diagnosis of prostate cancer. Enzalutamide
  • Enzalutamide brand name Xtandi
  • NSAA non-steroidal antiandrogen
  • Enzalutamide is clinically active in metastatic castration-resistant prostate cancer.
  • PSA level decreased more than 50% in 40 of 65 chemo-naive patients and 38 of 75 chemotherapy- treated patients.
  • Median time to radiographic progression was 56 weeks for chemo-naive patients and 25 weeks for the post-chemotherapy population.
  • Enzalutamide is a diarylthiohydantoin derivative, and is structurally related to earlier NSAAs such as flutamide, nilutamide, and bicalutamide. However, unlike the first-generation NSAA bicalutamide, enzalutamide does not promote translocation of AR to the cell nucleus and in addition prevents binding of AR to deoxyribonucleic acid (DNA) and AR to coactivator proteins. (Tran C. et al., Science. 324 (5928): 787-90 (2009)). As such, it has been described as an AR signaling inhibitor in addition to antagonist. (Antonarakis ES (June 2013). Translational Andrology and Urology. 2 (2): 1 19-120).

  • Enzalutamide has approximately 5- to 8-fold higher binding affinity for the androgen receptor (AR) compared to bicalutamide. As such, it has been described as an AR signaling inhibitor in addition to antagonist. Enzalutamide has only 2- to 3-fold lower affinity for the AR relative to the endogenous ligand dihydrotestosterone (DHT).

  • OMN54 An exemplary combination of Ganoderma lucidum (#9), Scutellaria barbata (#15), and Salvia miltiorrhiza (#14) was designated OMN54, based on the synergism displayed by certain combinations of extracts of the three botanicals when each botanical is between 1% w/w and 90% w/w of the combined composition. Extracts of the botanicals were preferably made in organic medium, such as alcohol, and non-alcoholic media including ester, lipid and the like. In a preferred embodiment the extracts were made in ethyl acetate medium.

  • OMN54 did not modulate pro-inflammatory proteins in unstimulated PBMC (suggesting safety for long-term use). In the presence of inflammatory stimulus (PHA mitogen), OMN54 suppressed inflammatory signaling (significant antiinflammatory activity). The effect of OMN54 in stimulated and unstimulated cells was observed for a number of proteins comprising cytokines, chemokines and growth factors.
  • the human prostate cancer cell line, LNCaP, is androgen sensitive and PSA positive.
  • OMN54 was tested for activity on LNCaP cell line, on the expression of specific genes associated with prostate cancer. High levels of Prostate Specific Antigen (PSA) are associated with prostate cancer. The significant suppression of the PSA transcript by OMN54 is considered beneficial in the treatment of prostate cancer.
  • PSA Prostate Specific Antigen
  • OMN54 displays profound antiproliferative effect on prostate cancer cells, inducing the apoptosis of both androgen receptor (AR)-positive (LNCaP) and AR-negative (DU-145) prostate cancer cell lines. OMN54 also displays NF-kappa B inhibition. The anti-inflammatory and antiproliferative functions displayed by the botanical composition also are effective against BPH. Thus, following detection of high PSA levels and prior to invasive tests for diagnosis of cancer, a low toxicity botanical formulation which is effective against both BPH and neoplastic states like prostate cancer and PIN, provides a promising regimen for first intervention.
