About this study

MRS-TU-2019 was a 12-month study designed to determine the efficacy of oral SOV2012-F1 as measured by the percentage of male hypogonadal subjects with average total testosterone (T Cavg) in plasma within the normal range after 90 days of treatment. This study included an AndroGel™ arm as a safety comparator; after the 90-day efficacy period, dosing continued for 9 additional months in both arms to gather safety data. This study also examined the percentage of SOV2012-F1-treated subjects with maximum total testosterone (Cmax) in plasma values after 90 days of treatment: a. ≤1.5 X upper limit of normal (ULN); b. 1.8 X ULN to 2.5 X ULN' and c. >2.5 X ULN. The study also included an adrenal cortical function substudy conducted in 30 SOV2012-F1 subjects and 15 AndroGel subjects. Four patient-reported outcome measures were also used during the study: IPSS, PDQ, SF-36 and IIEF.

Treatment and study plan

SOV2012-F1

Drug

oral preparation of testosterone undecanoate (TU)

AndroGel

Drug

topical testosterone gel 1.62%

Primary outcomes

  1. Percentage of Male Hypogonadal Subjects With Average NaF/EDTA Plasma Total Testosterone (T Cavg) Within the Normal Range Using Oral SOV2012-F1.

    Time frame: 90 days

    Efficacy assessment includes T Cavg calculated from NaF/EDTA plasma testosterone. The T Cavg is calculated as the 24-hour area under the curve (AUC), divided by 24, at Day 90, based on a fifteen blood samples (PK samples) taken over the 24-hours. The T concentration in each sample is measured using a validated LC-MS/MS method. The use of NaF/EDTA plasma tubes chilled after sample collection provides the most accurate values, as the prodrug TU may degrade post-sample collection, artificially inflating testosterone values.

Secondary outcomes

  1. Percentages of Participants in Each Category for Maximum Plasma Concentration

    Time frame: 90 days

    To determine the percentage of treated subjects with maximum plasma testosterone concentration (T Cmax) values (a) < 1.5X Upper Limit of Normal (ULN); (b) 1.8X to 2.5X ULN; and (c) > 2.5X ULN. For NaF/EDTA plasma, thresholds are 1200, 1440 and 2000 ng/dL of T. For serum, thresholds are 1500, 1800 and 2500 ng/dL of T. Note that the endpoint concerns only the investigational treatment SOV2012-F1 and the AndroGel results are reported for completeness. The reported percentages do not sum to 100% as the FDA criteria do not specify the percentage of subjects in the window of ≥ 1.5X and ≤ 1.8X the ULN.

Other outcomes

  1. Change From Baseline in the IPSS

    Time frame: Baseline (pre-treatment) to 90 days and 365 days

    Patient reported outcomes will be assessed by the International Prostate Symptom Score (I-PSS) Reporting a score on a scale 0 to 35 (asymptomatic to very symptomatic). Mean change from baseline is reported and is the difference between the score at Baseline (pre-treatment) and at Day 90 and Day 365. Thus, a positive value at Day 90 or Day 365 represents an increase in the score from baseline.

  2. Change From Baseline in the Psychosexual Daily Questionnaire (PDQ)

    Time frame: Baseline (pre-treatment) to 90 days and 365 days

    Patient reported outcomes are 7-day average score at baseline, and average change from baseline (CfB) at Day 90 and Day 365. Weekly daily average scores calculated for diaries completed at least 3 of 7 days.

    The three domains are:

    Sexual desire subscale 0=None, 1=very low to 7=Very High. Sexual enjoyment with/without partner subscale 0=None to 7=Very high enjoyment/pleasure. Partner availability not used in scoring. Positive CfB desirable.

    Positive and negative mood subscales 0=Not at all true to 7=Very true (Likert 7-point scale, 7-day average reported). Positive mood (sum of 4 questions) score range = 0 to 28; positive changes from baseline desirable. Negative mood (sum of 5 questions) score range = 0 to 35; negative CfB desirable.

    Weekly sexual activity subscale score is 7*(# of activities per week / # of days reported). Percent full erection uses scale of 0-100% (10% steps). Satisfaction with erection 0=not satisfactory to 7=very satisfactory. Positive CfB desirable.

  3. Change From Baseline in the SF-36

    Time frame: Baseline (Day 1, pre-treatment) and change from baseline at the End of Treatment (EOT)

    Patient reported outcomes assessed by the Short-Form Survey (SF-36). This scale assesses 8 health concepts:

    • limitations in physical activities because of health problems
    • limitations in social activities because of physical or emotional problems
    • limitations in usual role activities because of physical health problems
    • bodily pain
    • general mental health (psychological distress and well-being)
    • limitations in usual role activities because of emotional problems
    • vitality (energy and fatigue)
    • general health perceptions.

    Each domain is scored from 0-100 with a score of 0 = maximum disability and a score of 100 = no disability.

    End of Treatment (EOT) occurred either at time of early withdrawal from the study or at Day 365. The reported value is the change from baseline. A positive value at EOT indicates improvement in the measure towards less disability. The EOT Change from Baseline is simply the arithmetic difference between the Baseline and EOT scores.

  4. Change From Baseline in the IIEF

    Time frame: Baseline (Day 1, pre-treatment) and change from baseline at the End of Treatment (EOT)

    Patient reported outcomes are assessed by the International Index of Erectile Function (IIEF). A score of 0-5 (higher score indicating improvement) is awarded to each of the 15 questions that examine overall satisfaction (2 questions, total possible score=10), and the 4 main domains of male sexual function: erectile function (6 questions, total possible score=30), orgasmic function (2 questions, total possible score=10), sexual desire (2 questions, total possible score=10), and intercourse satisfaction (3 questions, total possible score=15).

    The IIEF results are reported at Baseline (Day 1, pre-treatment) and the change from baseline at the End of Treatment (EOT). EOT occurred either at time of early withdrawal from the study or at Day 365.

    The reported value is the change from baseline. A positive value at EOT indicates improvement in the measure. The EOT Change from Baseline is simply the arithmetic difference between the Baseline and End of Treatment scores.
