Primary Outcome Measures
NameTimeMethod
As of 07/03/2016:<br>Initial safety phase<br>1. Dose limiting toxicities<br><br>Randomised extension phase<br>1. Frequency of CTC grade III-IV toxicities with a focus on diarrhoea as the primary dose limiting toxicity<br>2. Decrease in uNTX from baseline to end of cycle 5 (approximately 15 weeks post trial entry). For patients who progress prior to the end of cycle 5, the decrease in uNTX from baseline to their end of study treatment visit will be used.<br><br>Previous primary outcome measures:<br>To evaluate the safety and toxicity of the combination of radium-223 and capecitabine
