Brief summary
This trial is investigating the impact of methadone rotation for management of cancer induced bone pain (CIBP), in comparison with other opioid rotation. Who is it for? You may be eligible for this study if you are aged at least 18 years old, have a diagnosis of solid tumour or haematological cancer with a predicted prognosis of greater than 8 weeks, have a diagnosis of CIBP and are currently taking a strong opioid (morphine, oxycodone or hydromorphone). Study details Participants will be randomly allocated (by chance) to one of two arms: Arm A: Methadone rotation for 14 days Arm B: Rotation to another strong opioid (morphine, oxycodone or hydromorphone) for 14 days All participants will be asked to complete questionnaires throughout the study assessing their pain levels. Information from this study will help investigators examine the efficacy and tolerability of methadone for providing pain relief to those with CIBP.
Interventions
Participants will be admitted to hospital and rotated from usual opioid to racemic methadone, with the initial dose administered orally or subcutaneously, in the event when the oral route is not available. The methadone dose is not prespecified and will be determined by the patients baseline opioid dose and calculated according to the European Association for Palliative Care and the European Society for Medical Oncology opioid conversion guidelines. The total daily methadone dose will be adminis
Participants will be admitted to hospital and rotated from usual opioid to racemic methadone, with the initial dose administered orally or subcutaneously, in the event when the oral route is not available. The methadone dose is not prespecified and will be determined by the patients baseline opioid dose and calculated according to the European Association for Palliative Care and the European Society for Medical Oncology opioid conversion guidelines. The total daily methadone dose will be administered in three or four divided doses for the first 48 hours, with the aim of achieving a twice to three times daily dosing after 5 days. This maintenance dosing scheduled will be ongoing for the duration of the study. Adherence to the intervention will be monitored daily through review of inpatient medication records
