Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Stage one. Open label dose ranging.
Eligible, consenting patients will be commenced on 10mg Sustained Release (SR) morphine (Kapanol) daily.
A diary will be completed twice daily by the participant for 2 days prior to intervention and then for 7 days. On Day 7 the participant will be visited at home and assessed for;
1. Side effects. Little or no side effects will continue the assessment.
2. Benefit. The participant will then be assessed for benefit from the intervention. No benefit will lead to an increased dose of SR morphine by 10mg for a further 7 days.
Participants will continue increasing doses of SR morphine until a dose provides benefit without side effects (to a maximum of 30mg daily). If participants continue to 30mg without side effects, but also without benefit they exit the study at that point and do not continue to stage 2.

Stage two. Long term effectiveness study.
Eligible participants will have reached a SR morphine dose where side effects are absent (or acceptable/minimal) and benefit has been established. Participants will remain on the dose established as part of Stage one.
A diary will be completed at weekly intervals to record ongoing dyspnoea scores, ongoing acceptability, and the emergence of any complications. In addition, participants will be monitored by telephone weekly for 2 months, then monthly until exit from the study.
Stage two will continue until
• Participant withdraws
• The participant is withdrawn, if the AKPS score falls to 30 or below
• Study completion; until participant numbers have been reached,.
• Or until death
Follow-up will include file review for hospitalisation, cessation of opioids, and introduction of other therapies such as oxygen.

Secondary outcome [1] 3182 0
To document and compare differential side effects and participant burden from varying doses. A safety monitoring telephone call will be made on day 4. On Day 7 the participant will be visited at home and assessed for;
1. Side effects. Unacceptable side effects will end the intervention as the participant experienced side effects from the lowest possible dose. Participation will end. Little or no side effects will continue the assessment.
2. Benefit. The participant will then be assessed for benefit from the intervention.
