|
E.2.2 | Secondary objectives of the trial |
Is morphine medication, used over three months better than placebo in people with chronic heart failure with regard to the following: o the distress and unpleasantness due to breathlessness, global impression of change of breathlessness o other symptoms such as daytime sleepiness, pain and sleep disturbance, o quality of life, o daily activity and function (including cognitive function), o use of health services and costs of health-care o severity of heart failure o toxicity over 3 months with placebo control o toxicity and benefit on breathlessness in the longer term |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patients with NYHA class III or IV symptoms due to heart failure as evidenced by: a) Echo: LVSD <40% EF, or at least "moderate" on inspection within last 3 months OR b) Echo showing LVEF > 40% plus left ventricular hypertrophy, left atrial dilation or abnormal diastolic function within last 3 months 2. NT-proBNP ≥1000 pg/mL OR BNP ≥250 pg/mL within last 3 months 3. Optimal medical management of heart failure which has not changed in the previous 2 weeks (see below) 4. Adequate renal clearance within previous 2 weeks. GFR ≥30ml/min (see Appendix A of protocol) 5. Grade 2 or more on the modified MRC dyspnoea scale (see Appendix A of protocol) 6. Aged 18 years or over.
Optimal treatment is defined as: o Reached target dose of (or be on maximally tolerated dose of, or be intolerant of) an inhibitor of the renin-angiotensin system shown to improve prognosis AND o Reached target dose of (or be on maximally tolerated dose of, or be intolerant of) a beta adrenoceptor antagonist shown to improve prognosis AND o Reached target dose of (or be on maximally tolerated dose of, or be intolerant of) an aldosterone antagonist As assessed by the clinician responsible for the usual care of the patient and reviewed by the study doctor at the recruiting centre prior to study entry. |

Have used morphine-based medications regularly (that is, most days) within the last month above the study dose. 5. Have known true morphine allergies or hypersensitivity to any of the tablet constituents as assessed by a clinician. 6. Have known central hypoventilation syndrome 7. Have been involved in another medicinal trial (CTIMP) within the past four weeks 8. Are pregnant or lactating 9. Have respiratory depression, head injury, paralytic ileus, acute abdomen, acute hepatic disease 10.

E.5 End points |
E.5.1 | Primary end point(s) |
Patient-rated average intensity of breathlessness in the past 24 hours using a 0 – 10 numerical rating scale (NRS), where 0 = no breathlessness and 10 = worst imaginable breathlessness, at 28 days. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Primary end point: 28 days
|
|
E.5.2 | Secondary end point(s) |
• Other aspects of breathlessness: worst intensity of breathlessness over previous 24 hours (NRS); distress and unpleasantness due to breathlessness (NRS); global impression of change • Assessment of related symptoms: Average pain over previous 24 hours (NRS); daytime sleepiness (Karolinska sleepiness scale) • Quality of sleep (Epworth Sleep Scale) • Assessment of activity and function (including cognitive function): 6 minute walk test (6MWT); ActivPAL activity monitoring; Montreal Cognitive Assessment (MoCA); NYHA class; Australia-modified Karnofsky Performance Status (AKPS) • Quality of life: Kansas City Cardiomyopathy Questionnaire-short form (KCCQ-SF) • Health economic assessment: The EuroQoL EQ-5D-5L and EQ-VAS; health service use • Toxicity symptoms (these will be checked at every study contact)
|
|
