A Multicenter Extension Trial to Evaluate the Safety of Testosterone Gel

Measurement of total testosterone level occur after subjects have been on a stabilized dose of testosterone gel for at least one month in the period between Month 3 and Month 6. The data were presented using descriptive statistics.

Time frame: Samples were collected at pre-dose; 2, 4, 6, 8, 10, 12 (±15 min for all), 18 (±2 hr), and 24 (±1 hr) hours post-dose (between Month 3 and Month 6, after subjects had been on a stabilized dose of Testosterone gel for at least 1 month)

Population: PP analysis population was used which comprises data from subjects who had 24 hr PK data for testosterone, with no major protocol violations.

Time frame: Samples were collected at pre-dose; 2, 4, 6, 8, 10, 12 (±15 min for all), 18 (±2 hr), and 24 (±1 hr) hours post-dose (between Month 3 and Month 6, after subjects had been on a stabilized dose of Testosterone gel for at least 1 month)

Data collected from the five domains of sexual functions were summarized by descriptive statistics. The domains are: 1. Erectile function (6 items, questions 1-5 and 15) (Score range: 1-30) 2. Orgasmic function (2 items, questions 9-10) (Score range: 0-10) 3. Sexual desire (2 items, questions 11-12) (Score range: 2-10) 4. Intercourse satisfaction (3 items, questions 6-8) (Score range: 0-15) 5. Overall satisfaction (2 items, questions 13-14) (Score range: 2-10) A score of 0-5 is awarded to questions 1-10 and a score of 1-5 is awarded to questions 11-15. Low score indicates severe dysfunction and a high score indicates no dysfunction in sexual function, in each domain.

Time frame: At Month 6

Population: ITT population was used which consists of all subjects who received at least one dose of the IMP. Of 145 treated subjects, 127 had available IIEF questionnaire results.

The MAF contains four sub-domains: 1. Severity (2 items, questions 1-2) (Score range: 2-20) 2. Distress (1 item, question 3) (Score range: 1-10) 3. Degree of interference in activities of daily living (11 items, questions 4-14) (Score range: 11-110) 4. Timing (2 items, questions 15-16) (Score range: 5-20) A score of 1-10 is awarded to each of the 14 questions across the 3 domains. The timing domain is categorical and was converted to 1-10 scale by multiplying each score by 2.5. Lower score in each domain indicates improvement in fatigue. To calculate GFI : Score of question 15 is converted to a 0-10 scale by multiplying each score by 2.5 and then sum scores of questions 1, 2, 3, average of 4-14, and newly scored question 15. A score of zero is assigned to question 2-16, if patient select 'no fatigue' to question 1. Question 16 is not included in GFI calculation. Range of GFI: 1 (no fatigue) to 50 (severe fatigue). The data were presented using descriptive statistics.

Time frame: At Month 6

Population: ITT population was used which consists of all subjects who received at least one dose of the IMP. Of 145 treated subjects, 127 had available MAF questionnaire results.

Data collected from the SF-12 questionnaire was used to assess improvement in the psychometrically-based physical component summary (PCS) and mental component summary (MCS). Both PCS and MCS contains four sub-domains: PCS: General Health (1 item), Physical Functioning (2 items), Role-Physical (2 items), Bodily Pain (1 item) MCS: Role-Emotional (2 items), Mental Health (2 items), Vitality (1 item), Social Functioning (1 item) The scale scores are calculated by summing responses across scale items and then transforming these raw scores to a 0-100 scale. Computerized scoring algorithms are used to produce norm-based scores for each scale (mean of 50 and SD of 10) as well as the PCS and MCS summary scores. A zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health. The data were presented using descriptive statistics.

In ADAM questionnaire, subjects had to respond in yes or no to 10 questions. A positive result (with severity and symptoms of low testosterone) on the questionnaire was defined as an affirmative answer (yes) to questions 1 or 7, or to any 3 other questions. The data were presented using descriptive statistics.
