Able to complete necessary assessments required as part of the trial 6. Life expectancy greater than two months 7. Due to receive palliative radiotherapy for bone pain
Exclusion criteria
Exclusion criteria: 1. Aged less than 18 years 2. Current gabapentin/pregabalin use 3. Significant renal impairment (plasma creatinine greater than 1.5 mg/ml, creatinine clearance less than 60 mmls/hr) 4. Change in any tumoricidal therapy before entering the study which may be expected to have an analgesic benefit during the study period 5.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To establish if radiotherapy and pregabalin gives superior analgesia in CIBP than radiotherapy alone. Primary and secondary outcomes will be measured at study baseline (date of first fraction of radiotherapy) and study endpoint (four weeks from study baseline). | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Background, spontaneous and movement-related pain 2. Total opioid requirements, i.e. background and breakthrough doses 3. Tolerability of pregabalin 4. Global quality of life scores (European Quality of Life [EuroQoL] thermometer) 5. Hospital Anxiety and Depression (HAD) scores 6. Changes in sensory responses as assessed by Quantitative Sensory Testing (QST). Modified short version for those patients who want to complete this (20 minutes). 7. Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) only to be done in conjunction with QST 8. Opioid side-effects 9. Withdrawal from study 10. Serious adverse events - pregabalin Primary and secondary outcomes will be measured at study baseline (date of first fraction of radiotherapy) and study endpoint (four weeks from study baseline). | — |
