Phase 2 outcomes paper part 113 Jul 2019 16:56
Just as an introduction, the International index of the Erectile Function (EF) questionnaire has a series of questions. Depending on your answers, you are given a certain number of points. These can be divided into the following categories
1. Erectile Function. (these questions determine the score for EF and determine the primary end point)
2. Orgasmic function (this makes up the secondary questionnaire which determines the secondary end point)
3. Sexual Desire (As per point 2)
4. Intercourse Satisfaction (as above)
5. Overall Satisfaction (as above)
The mild group had a EF score (item 1) of 17 to 25. The moderates had a score of 11 to 16. The severes a score of 10 or less. The mild and mild to moderates a score between 11 to 25.
Let's first discuss the primary end point. If you look at the study, it was heavily geared towards patients with mild ED, with a mean EF score of 20 from the UK and 22.4 in Poland. The experiment which used the lowest dose of 0.2% achieved a P value of less than 0.0001 on this group of patients. In other words there is less than 1 in ten thousand chance that it was by luck. It's possible that that the dose worked on the moderate patients that had an EF score at the upper end of the bracket for moderates (11-16), however I would not deem it a success on the moderates and severes and I would not pay too much attention on the mild and mild to moderate group. I would keep it simple as mild, moderates and severes.
So in summary there is less than 1 in ten thousand chance that it was by luck that it worked on the milds. The moderate cases it did not work and the severe cases it did not work (for the 0.2% dose)
Let's discuss the secondary end points now. The 0.2% dose of the MED gel performed across all patient groups when asked about whether it increased their sexual desire including the severe cases! When asked about intercourse satisfaction, all groups showed improvement apart from the severe cases. When asked about orgasmic function, all showed improvements. In summary, when it came to the secondary questionnaire which is mainly used for commercial claims, it performed exceptionally well.
