Further study details as provided by New York Presbyterian Hospital:

Primary Outcome Measures:
  • Measure the regression of CIN in women by cytology, colposcopy, and biopsy, [ Time Frame: 3 months ]
    To determine if oral DIM is effective in promoting the regression of CIN in women

Secondary Outcome Measures:
  • HPV colonization by commercial ELIZA test [ Time Frame: 3 months ]
    To correlate the response to DIM with HPV colonization

  • Adverse events reported by subjects and lab abnormalities i.e. CBC and SMA20 [ Time Frame: one year ]
    To assess for any adverse effects of oral DIM in women

Estimated Enrollment: 62
Study Start Date: September 2000
Study Completion Date: July 2010
Primary Completion Date: January 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: oral DIM (Active agent)
2mg/kg/day po of DIM
Drug: di indolylmethane (DIM)
This is the agent being studies. Similar agents have been reported to have potential activity.
Active Comparator: Red rice bran (Placebo)
this agent is not generally thought to be active but may be
Dietary Supplement: Red rice bran
this will act as the active comparator. The sponsor provided this as the "placebo" arm since it is a filler component of their DIM capsules

Detailed Description:
To determine if the use of oral Diindolylmethane (DIM), a marketed cruciferous vegetable based dietary supplement (BioResponse-DIM®), is associated with the regression of cervical dysplasia in otherwise healthy women. Additionally, the study aims to see how the use of the BioResponse-DIM supplement correlates with cervical HPV colonization, and to asses the tolerability of daily DIM supplementation
