A Study to Test Radium-223 With Docetaxel in Patients With Prostate Cancer
Recruiting
The purpose of this study is to compare any good and bad effects of using radium-223 along with docetaxel chemotherapy treatment versus using docetaxel alone. Earlier studies helped show that the combination is safe, but the combination has not been proven to work better than either drug alone. The goal of this study is to find out if combining docetaxel and radium-223 is better than giving either drug by itself.

MammaPrint, BluePrint, and Full-genome Data Linked With Clinical Data to Evaluate New Gene EXpression Profiles
Recruiting
The FLEX Registry will be implemented to operate as a large-scale, population based, prospective registry. All patients with stage I to III breast cancer who receive MammaPrint® and BluePrint testing on a primary breast tumor are eligible for entry into the FLEX Registry, which is intended to enable additional study arms at low incremental effort and cost. FLEX Registry will utilize an adaptive design, where additional targeted substudies and arms can be added after the initial study is opened.
