E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main research question is to evaluate the feasibility of conducting a randomised, double blind, placebo pilot trial in patients with end stage renal disease (ESRD) and depression. The treatment under investigation is Sertraline, a licensed anti-depressant. The study is split into four phases. Phase one will evaluate the number of ESRD patients eligible for this clinical trial. Phase two will assess the feasibility of conducting a randomised drug trial in this group of patients, by measuring the number who take part. Phase three will look at the safety and drug exposure of Sertraline in ESRD patients and phase four will explore the patient experience of participating in this trial. |
|
E.2.2 | Secondary objectives of the trial |
The secondary research questions will atttempt to quantify the variability in the outcome measures (including quality of life) for the treatment and placebo arms, allowing an assessment of effect sizes, effects of treatment centre, and bias due to missing data. The study will also try to evaluate the gain in the outcome measures in treated patients compared to those in the control group and whether changes in these measures over time can be attributed to treatment. This is a pilot study and a statistically significant outcome in this domain is unlikely. Establishing the effect size though will be of crucial importance in powering future definitive trials. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
For the prevalence and screening part of the study the inclusion criteria are: 1)Patients with ESRD and on haemodialysis. They will have started dialysis at least 3 months previously and have continued to receive dialysis in the 3 months prior to the invitation to participate in this study. 2)Adults aged 18 or over. 3)Patients who speak and read English sufficiently well to complete questionnaires. For the clinical trial part of the study the inclusion criteria are: 4)Patients with a BDI II score of 16 or above. 5)Patients, who according to the nephrologist, have more than one year prognosis. 6)Patients with a diagnosis of Major Depressive Disorder according to a DSM IV interview conducted by a psychiatrist. 7)Patients who score 18 or above on the Montgomery-Åsberg Depression Rating Scale (MADRS). |

E.5 End points |
E.5.1 | Primary end point(s) |
Our primary outcome for the study is the proportion of eligible patients approached who agree to enter the study and complete the study. In addition, for phase one, are main outcome is the number of people on haemodialysis who screen positive on the Beck Depression Inventory II. For phase three, to measure plasma levels of Sertraline in pre and post dialysis patients and phase four to explore the patients' views regarding the facilitators and barriers to participation in the trial. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The pilot trial is 6 months long and the primary endpoint will be evaluated at 6 months. |
|
E.5.2 | Secondary end point(s) |
There are a number of secondary outcomes. For phase one, we are interested in the eligibility of patients into this phase, looking at the number of haemodialysis patients that score positive on the Patient Health Questionnaire 9 and compare these scores with the Beck Depression Inventory II scores. For phase two, our secondary outcome measures are: 1) The proportion of patients who score positive on the BDI-II and are eligible for the psychiatric diagnostic interview. 2) The number of and reasons for patients not meeting the initial eligibility criteria applied by the CI/PIs in the trial outcome and safety and drug exposure phases. 3) The proportion of interview eligible patients who agree to take part in the psychiatric diagnostic interview. 4) The proportion of interview eligible patients who choose not to take part in the psychiatric diagnostic interview and reasons given (as well as alternative care chosen). 5) The proportion of patients who are diagnosed with a major depressive disorder according to the psychiatric diagnostic interview. 6) The proportion of eligible patients who agree to take part in the trial outcome and safety and drug exposure phases. 7) The proportion of eligible patients who refuse to take part in the trial outcome and safety and drug exposure phases and the reasons given (including description of alternative health options chosen). 8) The proportion of recruited patients who withdraw from the trial outcome and safety and drug exposure phases, the stage of withdrawal and the reason(s) for withdrawal. 9) The number of recruited patients who complete the baseline assessment. 10) The number of recruited patients who complete the follow-up assessments. 11) The proportions of complete and missing data, and the characteristics of the missing data. 12) The number, range and extent of adverse events reported. 13) To quantify the variability in the outcome measures (including QoL) for the treatment and placebo arms, allowing an assessment of effect sizes, effects of treatment centre, and bias due to missing data. 14) To evaluate the gain in the outcome measures in treated patients compared to those in the control group and whether changes in these measures over time can be attributed to treatment. For phase 3, our secondary aims are: 1) To compare the plasma Sertraline levels with clinical effectiveness (such as the Montgomery-Åsberg Depression Rating Scale, MADRS). 2) To compare the plasma Sertraline levels with AEs. For phase 4 are additional aims are: 1) To explore the views of patients regarding taking additional medication and the effects of the medication on them. 2) To explore the views of patients about the applicability and understanding of the measures/instruments used. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
We have two definitions for end of trial. The first definition of end of trial is LVLS. The data will be locked at this point. The second end of trial, is when the Sertraline samples are sent to the Cardiff Toxicology Laboratory, analysed and added to the data file. This will take place about 6 to 8 months after the LVLS. The data file will be unlocked and the additional data added. |
