7.Pathologic ECG, as assessed by the investigator. Max QTc-time on ECG: 450 ms in men and 460 ms in women
8.Abnormal laboratory values of such severity that participation in the study, in the opinion of the investigator, is questionable
9.Patients who are so debilitated by their disease that they are not assumed to be able to perform the assessments or handle the instruments used for evaluation of effect and/or are not able to consent

13.Clinically significant renal disease which may prevent the patient from completing the study and/or an elevation in serum creatinine of >1.5 times the laboratory reference.
14.Any surgical or medical condition which, in the opinion of the investigator, might interfere with the absorption, distribution, metabolism or excretion of OSU6162
15.Patients treated with Modiodal, Xyrem, Mirtazapine, Mianserin or metabolic enzyme inhibitors or inducers, or drugs with a narrow treatment window (e.g. warfarin, antiepileptics, cyclosporine) and individually modelled drugs such as lithium

Primary Outcome Measures

Name	Time	Method
Main Objective: The primary objective of this study is to evaluate the efficacy of OSU6162 with respect to sequela after aneurysmal subarachnoid haemorrhage with special emphasis on fatigue.;Secondary Objective: Key secondary objective is the safety and tolerability of OSU6162;Primary end point(s): The primary endpoint will be change from baseline in improvement score on Global Clinical Impression of Change (CGI-C) ;Timepoint(s) of evaluation of this end point: After 12 weeks of treatment with OSU6162 or placebo, with data collection at weeks 1, 6, 12, and 20 (20=8 weeks after treatment).
