 •	Male gender.
 •	18 years old or older.
 •	Hetero sexual.

 •	Signed informed consent and expected cooperation of the patients for the treatment and follow up must be obtained and documented according to ICH GCP, and national/local regulations.
 
 |  | 
| E.4 | Principal exclusion criteria | 
| Patients will be excluded from the study if they meet any of the following criteria: •	Known allergies for mecillinam, penicillin or cephalosporines.
 •	Metabolic anomalies of aciduretic type.
 •	Apparent underweight.
 •	Use of valporate.
 •	Use of mecillinam within the last two months.
 •	Under treatment with other anti-infective drugs.
 •	Use of immuno-modulative medication i.e. metotrexate, Interferone gamma, tumor necrosis factor inhibitors or monoclonal antibodies.
 •	If there are, in the opinion of the investigator, obvious reasons why the patient will fail to adhere to the treatment and follow-up protocol. I.e. Psychiatric or mental disorders, alcohol abuse or other substance abuse, language barriers or other factors which makes adherence to the study protocol impossible
