E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to investigate the effects of treatment with the SSRI escitalopram compared to placebo on morbidity and mortality in CHF patients with a current episode of major depression |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives of this study are: Major: To estimate the improvement of depression by escitalo-pram compared to placebo in depressed CHF patients. To assess whether possible reduction of morbidity and mortality (see primary objective) might be attributable to the improvement of depression.

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
1. SCREEN-MOOD Objective: To determine the prevalence and positive predictive value of PHQ-9 sum 11 in patients with systolic CHF of NYHA class >=II in a large cohort. To describe the correlation of PHQ-9 sum and its positive predictive value with patients gender, age and NYHA class. Patients: All subjects entering screening step 1
2. THROMBO-MOOD Objective: To determine the effect of the SSRI escitalopram on platelet activation in depressed patients with CHF. Patients: Consecutive subjects entering screening step 1 at the Center of Würzburg (expected number: n= 60) Additional data required: Markers of platelet activation comprise platelet surface expression of P-selectin and CD40 ligand, binding of fibrinogen to activated glycoprotein IIb/IIIa on the plate-let surface, and measurement of circulating platelet/leucocyte and platelet/monocyte aggre-gates. Whole blood will be sampled at baseline and after 6 months of therapy, immediately incubated with the respective antibodies and fixed. Flow cytometry will be performed within the next hours on the same day.
3. VASO-MOOD Objective: Vasoreactivity of large vessels is an accepted surrogate to monitor favourable and detrimental effects of pharmacotherapy on the atherosclerosis risk profile. We aim to deter-mine the effect of the SSRI escitalopram on endothelium-dependent and -independent vasoreactivity, large artery stiffness and pulse wave reflection in depressed patients with CHF and to investigate concurrent changes with markers of inflammation (see substudy THROMBO-MOOD) and heart failure severity. Patients: All subjects entering screening step 1 at the Center of Würzburg (expected number: n=100).
4. GENE-MOOD Objectives: a) to determine whether selected polymorphisms in candidate genes are associated with an increased risk for depression in CHF. Emphasis will be placed on candidate genes which have already been linked to depression and CHF (e.g., ACE or NOS3). b) to investigate whether polymorphisms in candidate genes affect plasma levels of escitalopram (pharmacogenomics, -kinetics). c) to test whether polymorphisms in candidate genes impact on the therapeutic response towards escitalopram (pharmacogenomics, -dynamics). The panel of candidate genes focuses on functional polymorphisms in the serotonergic system (e.g., the serotonin transporter 5HTT, 5HT2a, and p11). Patients: All subjects. Additional data required: DNA specimens (extracted from blood at the Center of Würzburg). Subsequently, candidate gene polymorphisms are determined by PCR and MALDI-TOF tech-niques.
5. OSMO-MOOD Objectives: a) to examine whether antidepressant medication with escitalopram modifies the water and sodium homeostasis in subjects with heart failure and comorbid depression along the trial, and to estimate the prognostic utility of markers involved in the osmo- and volume regulation as serum sodium, urine osmolality, fractional excretion of sodium and uric acid, co-peptin; b) to examine associations between severity of depression and anxiety (MADRS, PHQ-9, GAD-7), severity of heart failure (NYHA functional class, NT-proBNP levels) and the above described panel of markers of water and sodium homeostasis Patients: All subjects Additional data required: Copeptin measurement (determined from samples stored at the Center of Würzburg).
6. Fe-MOOD Objectives: We want to investigate the role of iron deficiency as predisposing factor and the prognostic relevance on morbidity and mortality of patients with heart failure and depression. Patients: All subjects Additional data required: measurement of Fe, Ferritin, Transferrin and iron binding capacity at baseline, 6, 12, 18 and 24 months (determined from routine blood samples in following visits or blood samples stored at the Center of Würzburg)

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the time from randomization until death or hospitalization for any reason, whatever occurs first. As an exception, elective hospitalization for clearly non-cardiac reason is considered to be censoring, not an event. In contrast to this, emergency hospitalization for seemingly non-cardiac reason is considered an event because circumstances causing the emergency situation might be related to some cardiac condition. As well, elective hospitalization for seemingly non-cardiac reason which, however, might be related to cardiac condition, is considered to be an event. In order to avoid bias when using this endpoint, the blinded independent Endpoint Committee (members: see Appendix to Clinical Study Protocol) will classify each hospitalization to be or not to be an event.
