Trial Outcomes & Findings for ESPRIT Study in Hypogonadal Men (NCT NCT01143818)

NCT ID: NCT01143818

Last Updated: 2011-10-17

Results Overview

The Aging Male Symptoms (AMS) test is self-administered and designed to assess symptoms of aging with a rating from none (0) to extremely severe (5) for 17 items from psychological (5 items), somatic (7 items), and sexual (5 items) categories. Total scores range from 17 (minimum) to 85 (maximum). The AMS total score was reported at baseline and at Month 6 and represented the sum of all the items. The percent change from baseline was calculated as the \[(AMS value at Month 6 - AMS value at baseline)/baseline value\] x 100.

Participant Flow

Participants enrolled in this study were newly-diagnosed for hypogonadism and treatment naive to testosterone preparations. A total of 1053 participants were enrolled but only 1049 were treated with AndroGel.

AndroGel (testosterone gel) 1% was prescribed according to the regional Summary of Product Characteristics with a starting dose of 50 mg testosterone/day (packaged as 1 sachet of 50 mg). Testosterone was applied once daily.

PRIMARY outcome

Timeframe: Baseline to Month 6

Population: The full analysis set included all participants in the safety analysis set who had an Aging Male Symptoms (AMS) score available at baseline and Month 6.

The Aging Male Symptoms (AMS) test is self-administered and designed to assess symptoms of aging with a rating from none (0) to extremely severe (5) for 17 items from psychological (5 items), somatic (7 items), and sexual (5 items) categories. Total scores range from 17 (minimum) to 85 (maximum). The AMS total score was reported at baseline and at Month 6 and represented the sum of all the items. The percent change from baseline was calculated as the \[(AMS value at Month 6 - AMS value at baseline)/baseline value\] x 100.

SECONDARY outcome

Timeframe: Baseline to Month 6

Population: The full analysis set included all participants in the safety analysis set who had an IIEF score available at baseline and Month 6.

The International Index of Erectile Function (IIEF) test is a validated 15 question assessment designed to measure changes in erectile function (6 items), orgasmic function (2 items), sexual desire (2 items), intercourse satisfaction (3 items), and overall satisfaction (2 items). The scores ranged from 0 to 5 on each item with a lower score indicating greater dysfunction. A total IIEF score of 0 (minimum) to 75 (maximum) was possible and represented the sum of all the items at baseline and Month 6. The percent change = \[(IIEF value at Month 6-IIEF baseline value)/IIEF baseline value\]x 100.

SECONDARY outcome

Timeframe: Baseline to Month 6

Population: The full analysis set included all participants in the safety analysis set who had an MFI score available at baseline and Month 6.

The MFI is a 20-item self-reported instrument designed to measure fatigue. Five scales measure different modes of fatigue: general fatigue (4 items), physical fatigue (4 items), mental fatigue (4 items), reduced motivation (4 items), and reduced activity items (4 items). The scores for each item range from 1 to 5. Each subscale includes 4 items with 5-point Likert scales and subscale scores range from 4 to 20 with a higher score indicating greater fatigue. The percent change=\[(MFI value at Month 6-MFI value at baseline)/MFI baseline value\] X 100.

SECONDARY outcome

Timeframe: Baseline to Month 6

Population: The full analysis set included all participants in the safety analysis set who had BMI available at baseline and Month 6.

The BMI was measured in kg/m\^2 and was reported at baseline and at the Month 6. BMI = weight (kg)/\[(height (m) x height (m)\] and was measured to 1 decimal point precision.
