Design outcomes

Primary

MeasureTime frame
Main Objective: The main objective is to investigate the effect of 12 weeks of erythropoietin (EPO) treatment on cognitive impairments in patients with bipolar disorder or depression in remission with cognitive difficulties;Secondary Objective: The secondary objective is to investigate whether an early change in neural activity in prefrontal cortex correlates with and predicts improvements of cognitive functions in patients with bipolar disorder or depression in remission with cognitive difficulties;Primary end point(s): Difference in the change of: (i) A collected measure of cognition (a composite score) encompassing the following measures: Rey Auditory Verbal Learning Test – Total Recall (RAVLT; Schmidt, 2004), the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Coding (Randolph, 1998), verbal fluency (with letter "D"; Borkowski, Benton, & Spreen, 1967), WAIS-III Letter-Number Sequencing (Wechsler, 1997), Trail Making Test Part B (TMT-B; Army Individual Test Battery, 1944), and Rapid Visual Processing (RVP) from Cambridge Neuropsychological Test Automated Battery (CANTAB), which cover attention, verbal learning and memory, and executive functions.;Timepoint(s) of evaluation of this end point: Primary end points will be evaluated at baseline (week 1), week 3 (2 weeks after treatment initiation), week 13 (1 week after treatment ending), and at 6 months follow-up

Secondary

MeasureTime frame
Secondary end point(s): Difference in the change of: (i) Cognition (attention and processing speed) measured with Rapid Visual Processing (RVP; CANTAB) (ii) Function and quality of life measured with: the Functional Assessment Short Test (FAST; Rosa et al 2007);Timepoint(s) of evaluation of this end point: Secondary end points will be evaluated at baseline (week 1), week 3 (2 weeks after treatment initiation), week 13 (1 week after treatment ending), and at 6 months follow-up
