- Imminent or established spinal cord compression based on clinical and/or imaging findings
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection requiring need for intravenous anti-microbials, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Clinically significant medical condition defined as:
- Cerebral infarction within 6 months of study treatment
- Transient ischemic attack within 3 months of study treatment
- Myocardial infarction within 6 months of study treatment

- History of clinically significant ventricular arrhythmias (e.g., ventricular tachycardia, ventricular fibrillation, torsade de pointes)
- Prolonged corrected QT interval by the Fridericia correction formula on the screening electrocardiogram (ECG) > 470 msec (as determined on 2 or more time points within a 24 hour period if the first ECG demonstrates a prolonged corrected QT interval) or family history of long QT syndrome
- History of Mobitz II second degree or third degree heart block without a permanent pacemaker in place

Arms of the Study
Arm 1
Arm 2
Experimental
Experimental
Arm I (radium Ra 223 dichloride, olaparib)
Arm II (radium Ra 223 dichloride)
Patients receive radium Ra 223 dichloride IV over 1 minute on day 1. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive olaparib PO BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI as well as blood sample collection and a tissue biopsy during screening and on study.
Patients receive radium Ra 223 dichloride as in Arm I. Patients with radiographic progression may crossover to Arm I. If patients have already completed all 6 infusions of radium, they will receive monotherapy with olaparib. If they have not yet completed all 6 radium-223 infusion, they will continue radium-223 infusion until completion and receive concurrent treatment with olaparib. Patients also undergo CT or MRI as well as blood sample collection and a tissue biopsy during screening and on study.
