Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
At each site, participants will be sequentially allocated a unique identifying number (ID) on referral to the study. This ID number will be used for all subsequent study documentation for that participant.
On notification of a participant, the pharmacist at each site will consult the strata table according to the strata determined by the HADS anxiety and depression subscales and will allocate the next code available according to the supplied strata table and dispense the active or inactive medicine delivered in a labeled starter pack. The participant ID, allocation code, dates of request, preparation, and dispensing will be recorded in a log maintained by the pharmacist.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation schedules have been developed by an organisation not involved in this study. Treatment for each participant will be allocated according to a block randomisation schedule, held by the Central Registry Clinical trials Pharmacist, in a 1:1 ratio for each treatment arm. Block randomisation will ensure even allocation to each code.

Summary
Brief summary
Breathlessness continues to be a major clinical problem for many people with advanced progressive illnesses such as cancer, end-stage cardiac failure or chronic obstructive pulmonary disease even when they are receiving the best treatment for the underlying disease. Although there are some interventions that may offer benefit (oxygen therapy, sustained release low dose morphine), there is still a need for a wider range of interventions to meet the needs of people with refractory breathlessness.

Sertraline, an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class, is primarily used to treat major depression as well as obsessive–compulsive, panic, and social anxiety disorders. Previous research has suggested that treatment of concomitant mood or anxiety symptoms can improve dyspnoea however studies are needed to further clarify its potential benefits for the treatment of breathlessness.

The research team has conducted a Phase II double blind, titrated dose, multi-site placebo controlled pilot study of sertraline (ACTRN12608000253303) using the proposed inclusion and exclusion criteria and the measures proposed in this study design. The pilot study has demonstrated acceptability and feasibility of this study, however further Phase III data is needed in order to ensure that this is a well tolerated and effective intervention suitable for a broad range of people with refractory breathlessness.

This study will evaluate critically a new but theoretically useful therapy whose role needs to be carefully defined. Although sertraline has been used in small uncontrolled studies, the evidence for a net clinical benefit is inadequate.

Aim: The primary aim is to test the efficacy of sertraline compared with placebo in relieving the sensation of intractable breathlessness. Secondary aims focus on the impact of the sertraline on improving quality of life (QOL), dyspnoea-related anxiety and depression, adverse effects, function and clinical predictors of benefit.
