Design outcomes

Primary

MeasureTime frame
To evaluate efficacy of treatment with PSD502 compared with placebo in subjects with PE as measured by: 1. Changes in mean IELT from baseline to during three-month double-blind treatment 2. Changes in selected IPE domains from baseline to month three

Secondary

MeasureTime frame
1. Change in selected IPE domains from baseline to three months 2. Proportion of subjects with short mean IELT during the three months of double-blind treatment 3. Change in mean IELT from baseline 4. Subject and partner PEP scores 5. Evaluation of the safety and tolerability of PSD502 compared with placebo in subjects with PE as measured by adverse event (AE) and serious adverse event (SAE) data for both the subject and his sexual partner, collected throughout the study
