Outcome Measures

Primary Outcomes (1)

  • To Determine the Effect of Short-term Intake of Daily Dutasteride Prostate Cancer Volume, Distribution Within the Gland and Gleason Score Sum in Patients in Comparison to Placebo After Adjusting for Changes in Prostate Gland Volume.

    The effect of Dutasteride intake on the following parameters as detected by mapping biopsy vs. initial trans-rectal biopsy in the treatment arm and the control group: change in prostate gland volume, change in distribution within the gland, and change in Gleason score sum.

    24 Months

Study Arms (2)

Dutasteride

EXPERIMENTAL

The drug, Dutasteride, will be administered at 0.5 mg dose and given everyday (QD), for 3 months.

Drug: Dutasteride

Placebo

PLACEBO COMPARATOR

The placebo group will receive a placebo drug for 3 months, instead of the intervention drug, Dutasteride.

Other: Placebo

Interventions

Dutasteride will be administered at 0.5 mg dose and it will be given every day (QD), for approximately 3 months, followed by 3D mapping biopsy.

Also known as: Avodart
Dutasteride
PlaceboOTHER

The placebo group will receive the same standard of care as the intervention group, but instead of receiving the intervention drug, Dutasteride, participants will receive a placebo drug for the same 3 month period.
