Summary
Many people who have undergone subarachnoid hemorrhage from an aneurysm (an artery of a vein in the brain) struggle with a pronounced fatigue as well as a number of other sequelae such as impaired concentration, memory deficits and emotional problems. Exhaustion is often permanent and can lead to a significant worsening of quality of life and be the cause of disability. This condition does not only have major consequences for the individual who is affected, but also for their families and for society. So far no effective treatment for fatigue has been found. The drug OSU6162 has shown a beneficial effect on fatigue and other impairments after stroke and after traumatic brain injury. There is good reason to believe that OSU6162 can also improve fatigue and other impairments after aneurysm bleeding and thus increase the chance of returning to the level of daily function they had before the bleeding. The study is double blinded and measures the effect of OSU6162 and placebo on fatigue and neuropsychological function.

Criteria
Patients that have undergone aneurysmal subarachnoid hemorrhage (aSAH) from Health-region
South-East.

Inclusion Criteria:

- Signed written informed consent

- > 18 years old

- Aneurysmal subarachnoid haemorrhage >12 months prior to the start of the study.

- Diagnosed with post SAH syndrome/fatigue at ≥12 months after their hemorrhage

- Post-menopausal or using adequate contraceptive measures

- Female patients of childbearing potential using a highly efficient method of
contraception (i.e. a method with a failure rate of less than 1% [e.g.
sterilisation, hormone implants, hormone injections, some intrauterine devices,
or vasectomy in partner])

- Male patients agreeing to use condoms during the study and for 3 months after the
end of the study/last dose of the investigational medicinal product, or male
patients with a partner who is using a highly efficient method of contraception
(as described above)

Exclusion Criteria:

- Residual symptoms following other pathologies than aSAH

- Not adequately treated hydrocephalus secondary to aSAH

- Diagnosed with epilepsy, neurodegenerative disease, cerebral paresis, tumor cerebri,
cerebral arterio-venous malformations

- Patients that have undergone brain surgery, have been hospitalized for head trauma, or
suffered intracranial hemorrhage, stroke, or infectious brain diseases within the last
12 months

- Active substance abuse (drug screen taken at baseline)

- Current pregnancy or breast-feeding, or intention to become pregnant within 3 months
after the last dose

- Women of childbearing age not using contraceptives

- Pathologic ECG, as assessed by the investigator. Max QTc-time on ECG in excess of 480
ms or any of these conditions that can increase QT related incidences: long QT
syndrome or family history of long QT syndrome, hypothyreoidism, hypocalcemia,
significant potassium deviations, type 1 diabetes with prolonged QT, and cardiac
insufficiency

- Abnormal laboratory values of such severity that participation in the study, in the
opinion of the investigator, is questionable

- 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

- Patients that speak so poorly Norwegian that they are not able to answer the
questionnaires or undergo neuropsychological testing

- Previous treatment with OSU6162

- Clinically significant liver disease which may prevent the patient from completing the
study and/or an elevation in either total bilirubin, alkaline phosphatase, LDH, SGOT
of >2 times the laboratory reference

- 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.

- Any surgical or medical condition which, in the opinion of the investigator, might
interfere with the absorption, distribution, metabolism or excretion of OSU6162

- 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

- Use of drugs capable of inducing hepatic enzyme metabolism (e.g., barbiturates,
rifampicin, carbamazepine, phenytoin, primidone) within 30 days prior to the start of
the study (or 5 half-lives of the inducing agent, whichever is longer)

- Antipsychotic treatment

- Patients treated with "unstable therapies", i.e., treatments that have not been at the
same dose for at least 6 weeks prior to inclusion in this study. The treatment must
also remain unchanged during the study period. Insomnia medication and other PRN
medications are allowed.

- Use of acute or chronic medications for other medical conditions are allowed based on
the investigator's judgement. Occasional use of over-the-counter (OTC) medication is
not allowed during the study or one month prior to inclusion.
