Participant Flow

The study opened on October 21, 2010 with an accrual goal of 30 patients with firs the patient enrolled March 3, 2011. The study was designed as a randomized blinded drug/placebo study but was amended to a single arm drug study and accrual reduced to 18. Study closed permanently on May 28, 2014 due to low accrual with 12 patients treated on study.

Patients entered the study and were treated in a double blinded fashion with a ration of 2:1 Genistein:Placebo. Unblinding occured if it was medically necessary otherwise blinding was maintained until the time of data review.

PRIMARY outcome

Timeframe: At screening, after 1-month of treatment, at surgery and at 1 and 12 months after surgery

Population: Data was not collected for analysis of this endpoint due to the study closing before the accrual goal was met.

Blood will be collected to analyze the number of CPC's at screening, after 1-month of treatment, at surgery and at 1 and 12 months after surgery.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: At baseline, 1 and 12 months after surgery

Population: Data was not collected for analysis of this endpoint due to the study closing before the accrual goal was met.
