Design outcomes

Primary

MeasureTime frame
As of 07/03/2016: Initial safety phase 1. Dose limiting toxicities Randomised extension phase 1. Frequency of CTC grade III-IV toxicities with a focus on diarrhoea as the primary dose limiting toxicity 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. Previous primary outcome measures: To evaluate the safety and toxicity of the combination of radium-223 and capecitabine

Secondary

MeasureTime frame
As of 07/03/2016: 1. Safety endpoints 1.1. Adverse events (AEs) and serum biochemistry and haematology abnormalities graded according to the Common Toxicity Criteria for Adverse Events (CTC) version 4.03 1.2. Serious adverse events 1.3. Dose delays and reductions due to toxicity 2. Efficacy endpoints 2.1. Changes from baseline in serum bone turnover markers (B-ALP, uNTX, P1NP, CTX and 1CTP) throughout the study period 2.2. Time to occurrence of 1st symptomatic skeletal event (SSE). This is time from registration / randomisation to 1ST SSE. Patients who do not experience an SSE by the time of final analysis will be censored at the last time known to have not experienced as SSE, study withdrawal, start of new treatment or death 2.3. Time to progression of bone disease based on unequivocal progression of existing bone lesions or appearance of one or more new osteolytic bone lesions. This is time from registration/randomisation to progression in bone. Patients who do not progress in bone by time of final analysis will be censored at the last time known to have not progressed in bone, study withdrawal, start of new treatment or death 2.4. Time to progression of extraskeletal disease. This is time from registration / randomisation to progression in extraskeletal non bony sites. Patients who do not progress outside bone by time of final analysis will be censored at the last time known to have not progressed outside bone, study withdrawal, start of new treatment or death 3. Clinical benefit endpoints 3.1. Pain scores using the Brief Pain Inventory (BPI) 3.2. Quality of life using the EORTC BM-22 bone metastases module Previous secondary outcome measures: To evaluate the effect of radium-223 on other bone turnover markers (P1NP, CTX, 1CTP, B-ALP)
