E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To measure the effectiveness, compared to placebo, of 1 mg and 2 mg doses of VR776 administered via the Aspirair inhaler on the IVELT (intravaginal ejaculatory latency time) measured by stopwatch and recorded by the partner during sexual intercourse. |
|
E.2.2 | Secondary objectives of the trial |
To assess the safety and tolerability of single and as required use of repeat inhaled doses of VR776 in healthy male patients with premature ejaculation.
To assess the patients’ satisfaction and control of ejaculation during treatment with 1 mg and 2 mg doses of VR776 administered via the Aspirair inhaler compared to placebo.

Have a confirmed mean IVELT of of less than or equal to 2 minutes during the run in period; 12. Sexual partner able and willing to use a stopwatch to fulfil the study requirements; 13. Able to read, comprehend, and write English at a sufficient level to understand and complete study related materials; 14. Patient willing to refrain from any (non-study) pharmacological intervention, behavioural or other technique to delay ejaculation during intercourse during the study; 15.

E.4 | Principal exclusion criteria |
1. History of clinically significant allergies; 2. Treatment in the last 6 months for depression, psychiatric disorders, mood disorders, schizophrenia, substance abuse or anxiety disorders; 3.

History of myocardial infarction in the previous 3 months or history of angina; 8. History of glaucoma, pyloric stenosis to the bladder or history of benign prostatic hypertrophy; 9. FEV1 less than 80% of predicted; 10. History of intolerance to tricyclic antidepressants; 11. Current treatment with any drug known to interact with clomipramine including MAOIs, carbamazepine, phenytoin, neuroleptics, barbiturates, anticholinergics, sympathomimetics, cimetidine, quinindine, antihypertensives and thyroid treatments; 12. Participation in a study with a new molecular entity during the previous 4 months or any other clinical trial during the previous 3 months; 13. Partner unwilling to give informed consent or unable to operate a stop–watch; 14. Any evidence to suggest the patient will be unable to use the Aspirair inhaler correctly; 15.
