Clinical Trial Summary

The purpose of this study is to determine if treatment using a medication (anastrozole/Arimidex), which lowers estrogen levels in the blood is better than placebo, a tablet that does not contain any active medication, when combined with testosterone replacement to treat reproductive and sexual dysfunction in men with epilepsy. Anastrozole, the medication that is currently under study, does not, at this time, have FDA approval for use for this indication.

Description:

This is a three-month study where baseline information is collected at the first visit and then each patient is started on treatment with testosterone supplementation and either anastrozole or placebo. Lab tests, seizure frequency, sexual function and mood will be monitored on a monthly basis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Sexual Function Scores, Calculated Using S-Score and Reynolds' Sexual Questionnaires, Will Increase More Anastrozole and Testosterone Treatment Than With Placebo and Testosterone Treatment.	S-Scores and Reynolds Questionnaire scores were assessed at baseline and once a month over three months. The average change in score for each questionnaire over the 3 month study was reported. The S-Scores questionnaire measured sexual function and consisted of four questions with five possible answers. The total scale range was 0-20, with higher scores were considered better. S-Scores that were greater than or equal to 16/20 were considered normalized S-Scores. Reynolds Questionnaire is a 21 item survey that monitors sexual interest, activity, satisfaction, and function. The scale for the Reynolds questionnaire for sexual interest was from 0-12, with higher scores being better. The scale for sexual activity was 0-41 with higher scores being better. The sexual satisfaction scale was from 0-21 with higher scores being better. The scale for sexual function was from 0 to -12 with lower scores being better.	3 month average
Secondary	The Proportion of Men Who Achieve Normalization of Sexual Scores (Sexual Interest Function,) Using Anastrozole and Placebo	The proportion of men who achieve normalization of sexual scores (scores greater than or equal to 16/20) on anastrozole (T-A) and those on placebo (T-P) are reported. Both Men who achieve normalization of sexual scores and those who did not achieve normalization of sexual scores were reported for anastrozole (T-A) treatment group and the placebo treatment group. Sexual scores were gathered once per month for three months with the average of the three months reported.	Assessed for 3 months
Secondary	Bioavailable Testosterone Levels in Subjects on Anastrozole (T-A) and Subjects on Placebo (T-P).	Bioavailable testosterone levels were measured at baseline and once a month over the three month study. The average change in bioactive testosterone levels from baseline to the end of the three month study was reported.	Assessed for 3 months
Secondary	Estradiol Levels in Subjects on Anastrozole (T-A) and Subjects on Placebo (T-P).	Estradiol levels were measured once a month over the three month study in subjects taking anastrozole (T-A) and in subjects taking placebo (T-P). The average change in estradiol levels was reported.	Assessed for 3 months
Secondary	The Bioavailable Testosterone and Estradiol Ratio in Subjects Taking Anastrozole and Subjects Taking Placebo.	Bioavailable testosterone and estradiol levels were measured once a month over the three month study in subjects taking anastrozole and subjects taking placebo. The bioavailable testosterone and estradiol levels for the three months were averaged for each subject. The ratio between the average bioavailable testosterone level and average estradiol levels were reported.	Assessed for 3 months
Secondary	Bioavailable Testosterone and Luteinizing Hormone Ratios in Subjects Taking Anastrozole (T-A) and in Subjects Taking Placebo (T-P).	Bioavailable Testosterone and luteinizing hormone levels were measured once a month over the three month study in the treatment and placebo group. The bioactive testosterone and luteinizing hormone levels were averaged for the three months. The ratio between the average bioactive testosterone level and average luteinizing hormone levels were reported.	Assessed for 3 months
Secondary	Estradiol and Luteinizing Hormone Ratios in Subjects Taking Anastrozole (T-A) and in Subjects Taking Placebo (T-P).	Estradiol and luteinizing hormone levels were measured once a month over the three month study in the treatment and placebo group. The estradiol and luteinizing hormone levels were averaged for the three months. The ratio between the average estradiol levels and average luteinizing hormone levels were reported.	Assessed for 3 months
Secondary	Changes in Seizure Frequency in Subjects Taking Anastrozole (T-A) and Subjects Taking Placebo (T-P).	The average change in number of seizures over the 3 month study for the depotestosterone plus anastrozole (T-A) and depotestosterone plus placebo (T-P) were reported.	Assessed for 3 months
Secondary	Changes in Energy, Mood and Anxiety Scores for Subjects Taking Anastrozole (T-A) and for Subjects Taking Placebo (T-P).	Changes in energy, mood and anxiety scores were measured using The Beck Depression Inventory II and the POMS questionnaire. The Beck Depression Inventory II questionnaire consisted of 21 questions, each with answers ranging from 0-3. The answers for each question were summed. The scale ranged from 0-63 with higher scores meaning a higher depression score (worse score). The POMS questionnaire had a total of 65 questions that measured tension, depression, anger, vigor, fatigue and confusion. The total POMS score ranged from 0-200, with lower scores being better. The POMS tension score ranged from 0-36 with lower scores being better. The POMS depression score ranged from 0-60 with lower scores being better. The POMS anger score ranged from 0-48, lower scores being better. The POMS vigor score ranged from 0-32, lower scores being better. The POMS fatigue score ranged from 0-28, lower scores being better. The POMS confusion score ranged from 0-28 with lower scores being better.	Assessed for 3 months
