Agents that inhibit cholesterol synthesis are being investigated in cancers dependent upon cholesterogenesis. Red yeast rice (RYR), is a reddish-purple fermented rice, containing statins which are known to inhibit cholesterol synthesis. Laboratory studies have also shown that RYR has direct effects on androgen dependent and androgen independent prostate cancer cells, inhibiting their growth. It is thought that RYR may have clinical benefit in those subjects with localized prostate cancer who have chosen to be managed by active surveillance.

Further study details as provided by Sunnybrook Health Sciences Centre:

Primary Outcome Measures:
  • Expression of Ki-67 and p27 biomarkers [ Time Frame: 6 months ]
    Determine effect of red yeast rice therapy on expression of ki67 and p27 biomarkers in a post-treatment biopsy

Secondary Outcome Measures:
  • PSA kinetics [ Time Frame: 6 months ]
    Determine effect of red yeast rice daily therapy on PSA kinetics in men on active surveillance for localized prostate cancer

  • Presence of prostatic interepithelial neoplasia [ Time Frame: 6 months ]
    To evaluate the effect of red yeast rice daily therapy on grade and the presence of prostatic intraepithelial neoplasia (PIN) in post treatment biopsy

  • Expression of hs-CRP and cardiac CRP [ Time Frame: 6 months ]
    To assess the effect of red yeast rice therapy on the expression of high sensitivity C-reactive protein (hs-CRP) and cardiac C-reactive protein (CRP) in serum

Estimated Enrollment: 60
Study Start Date: January 2013
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: red yeast rice (RYR)
Two RYR capsules three times daily for a minimum of 6 months
Drug: Red yeast rice
Other Name: Aliperol

Detailed Description:
Red yeast rice has been promoted as a safe and effective alternative to statin therapy in the treatment of hypercholesterolemia. Red yeast rice has the potential to slow prostate cancer growth by inhibiting cholesterol and androgen biosynthesis. There is a strong rationale for the use of RYR in patients being managed with active surveillance for localized, low risk, prostate cancer. To date, no human studies utilizing RYR in this setting have been reported.
