E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this study is to explore the prophylactic (prophylaxis of deterioration) or curative efficacy and safety of long-term (12 and 24 weeks) daily administration of vardenafil therapy (administration at night) versus vardenafil PRN on erectile dysfunction in men with mild or mild to moderate, predominantly organic ED. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objective is to assess descriptively whether this estimated treatment effect depends upon the duration of daily dosing of the PDE-5 inhibitor. Furthermore, it shall be assessed descriptively whether or not the immediate and the possible sustainable effect on ED corresponds with an effect on patients' satisfaction by using a validated ED-specific questionnaire (TSS). |

E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
E.3 | Principal inclusion criteria |
Males 18-64 years of age Mild or mild to moderate ED (defined as >15 and <21 score points according to the Erectile Function Domain Score from IIEF as assessed at the randomisation visit) History of at least one of the following conditions: Diabetes mellitus type 2, hypertension, peripheral arterial occlusive disease Stable, heterosexual relationship for more than six months Documented, signed and dated written Informed Consent

E.4 | Principal exclusion criteria |
A) Previous or Current Medical Conditions Any unstable medical, psychiatric, or substance abuse disorder that, in the opinion of the Investigator, is likely to affect the subject's ability to complete the study or precludes the subject’s participation in the study Presence of penile anatomical abnormalities (e.g. penile fibrosis or Peyronie’s disease) in the opinion of the Investigator would significantly impair sexual performance Primary hypoactive sexual desire Spinal cord injury History of glaucoma History of surgical prostatectomy (transurethral intervention not excluded) Hereditary degenerative retinal disorders such as retinitis pigmentosa History of positive test for Hepatitis B surface antigen (HbsAg) or Hepatitis C Known severe chronic or acute liver disease, including history of moderate (Child-Pugh B) or severe (Child-Pugh C) hepatic impairment Clinically significant chronic hematological disease which may lead to priapism such as sickle cell anemia, multiple myeloma or leukemia Clinically significant bleeding disorder Significant active peptic ulceration Any underlying cardiovascular condition including e.g. unstable angina pectoris or ventricular failure NYHA stages III or IV, that would preclude sexual activity; symptomatic angina pectoris History of myocardial infarction, stroke, or life-threatening arrhythmia within the prior 6 months Uncontrolled atrial fibrillation/flutter at screening (ventricular response rate > 100 bpm) Resting hypotension (a resting systolic blood pressure of <90 mm Hg or diastolic blood pressure of < 50 mmHg) Insufficiently controlled hypertension: In patients known to be hypertensive, hypertension has to be sufficiently controlled with antihypertensives in the opinion of the physician treating the hypertension. In addtion, resting blood pressure at visit 1 (singular measurement not appropriate to judge on control of hypertension) must not be >170 mmHg (systolic) or > 110 mmHg (diastolic) irrespective of a patient having been classified as hypertensive or not. Symptomatic postural hypotension within six months of Visit 1 History of malignancy within the past 5 years (other than squamous or basal cell skin cancer) Life expectancy <3 years Clinical diagnosis of significant untreated sleep apnea or working night shifts (e.g. 23:00h to 7:00 h). Diabetes mellitus type 1
B) Concomitant Medication Nitrates or nitric oxide donors Oral or injectable or transdermally applied androgens Anti-androgens Anti-coagulants, with the exception of anti-platelet agents Any of the following potent inhibitors of cytochrome P- 450 3A4: potent inhibitors: HIV protease inhibitors (indinavir, nelfinavir, ritonavir, atazanavir, lopinavir, amprenavir, saquinavir), makrolid/-ketolid antibiotics (clarithromycin, erythromycin, telithromycin), anti-mycotic agents (itraconazole, ketoconazole [topical forms are allowed]), anti-depressants (nefazodon) less potent inhibitors: quinupristin/-dalfupristin, fluconazol, amiodaron, diltiazem, fluvoxamin, verapamil, valproinic acid, fluoxetin; grapefruit juice Any investigational drug (including placebo) within 30 days of Visit 1 Any treatment for ED other than study medication during the study, including oral medications, vacuum devices, constrictive devices, injections or urethral suppositories Alpha blockers during randomised treatment and wash-out.
C) Abnormal Laboratory Values Serum total testosterone level >25% below the lower limit of normal (according to the range of the testing laboratory). HbA1c greater or equal 9 (“excessively uncontrolled diabetes”) Serum creatinine > 3.0 mg/dL Creatinine clearance < 30 ml/min Elevation of AST and/or ALT >3X the upper limit of normal
D) Other Exclusions Known hypersensitivity to vardenafil, Bay 38-9456 (also known as SB-782528) or any component of the investigational medication Subjects unwilling to cease use of vacuum devices, intracavernosal invection, Viagra®, or other therapy for ED. Patients illiterate or are unable to understand the questionnaires or subject diary Patients unwilling or unable to complete the subject diary or questionnaires
