| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| To demonstrate in stable angina patients undergoing elective PCI the superiority of molsidomine, used as an add-on treatment on standard care therapy, over placebo on improving the endothelial function (Endoscore measured by RH-PAT) after 12 months of treatment. | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
To estimate the effect of molsidomine and placebo on the augmentation index (an index of arterial stiffness) as measured by RH-PAT.
 To determine the impact of molsidomine on the following endothelial biomarkers: 
 	hs-CRP
 	sICAM-1
 	IL-8
 	Myeloperoxidase (in terms of concentration and activity)
 	Myeloperoxidase oxidized-LDL (MOx-LDL)
 	Isoprostanes
 	Microparticles from the endothelium, leukocytes and platelets
 To compare the rate of serious cardiovascular events (SCEs) in the two groups.

 •	Patients who the investigator believes that they and/or their Legally Acceptable Representative (LAR) can and will comply with the requirements of the protocol.
 •	Written informed consent from the patient or from the LAR.
 All patients must satisfy the following criterion at randomisation (Visit 2 - Month 0):

 | 
 
 
 |

•	Pre-menopausal women.
 •	Patient with a clinically-active malignancy.
 •	Known major renal insufficiency (creatinine 2.0 mg/ml) or known significant hepatic insufficiency (SGOT 2 times upper limit, total bilirubin 1.5 times upper limit).
 •	History of psychological disorder, mental dysfunction, alcohol or drug abuse or any other factor which might interfere with the ability to cooperate in the study.
 •	Participation in another clinical trial which has not yet reached its primary endpoint or with the same primary endpoint during the previous month.
 •	Concurrently participating in another clinical study, at any time during the study period, in which the subject will be exposed to an investigational or a non-investigational product (vaccine, drug or device).
 •	Hypersensitivity to molsidomine or to one of its excipients.
 •	Peri-procedural infarction: CK-MB >3 times the upper reference limit (Thygesen et al., 2007).
 •	Clinically significant abnormal pre-PCI CK-MB and troponin: any elevation above the upper reference limit (Thygesen et al., 2007).
 •	Intolerance to galactose, deficiency in Lapp lactase or glucose-galactose malabsorption.
 •	Left ventricular insufficiency (NYHA class III or IV) with an ejection fraction <35%.
 •	Acute circulatory insufficiency (e.g. cardiogenic shock).
