  Purpose

The purpose of this study is to obtain psychological response and user preference information on the use of the T jet® device versus the traditional subcutaneous injection administration of Tev Tropin®.

This study will compare subject-reported injection anxiety immediately before the administration of each dose of Tev-Tropin® between a needle-syringe injection method and a needle-free injection method (T-jet®)

Growth Hormone Deficiency
 Device: T-jet® containing TevTropin®
Procedure: TevTropin® needle-syringe injection method

Primary Outcome Measures:
  • Subject-reported Injection Anxiety Immediately Before Administration [ Time Frame: 28 days; Period 1: 14 days, Period 2: 14 days ] [ Designated as safety issue: No ]
    The difference in mean subject-reported injection anxiety between the two injection methods as recorded on a 5 point scale immediately before administration, which scale consisted of a row of five faces with values from 1(most positive)to 5(most negative or greater anxiety.) The score is an average of the Period 1 (Days 1-14) and Period 2 (Days 15-28) assessments; like groups were combined and then averaged. There were 3 visits: Visit 1 (Begin Period 1) Screening and Randomized assignment, Visit 2 (first day of Period 2) Cross over to other assignment, Visit 3 End of Study.


Secondary Outcome Measures:
  • Subject-reported Injection Pain Immediately Following Administration. [ Time Frame: 28 days; Period 1: 14 days, Period 2: 14 days ] [ Designated as safety issue: No ]
    The difference in mean subject-reported injection anxiety between the two injection methods as recorded on a 5 point scale immediately before administration, which scale consisted of a row of five faces with values from 1(most positive)to 5(most negative or greater anxiety.) The score is an average of the Period 1 (Days 1-14) and Period 2 (Days 15-28) assessments; like groups were combined and then averaged. There were 3 visits: Visit 1 (Begin Period 1) Screening and Randomized assignment, Visit 2 (first day of Period 2) Cross over to other assignment, Visit 3 End of Study.

  • Subject or Caregiver Reported Perception of Ease of Preparation as Recorded Weekly on a 5-point Scale. [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
    The difference in mean subject-reported injection anxiety between the two injection methods as recorded on a 5 point scale immediately before administration, which scale consisted of a row of five faces with values from 1(most positive)to 5(most negative or greater anxiety.) The score is an average of the Period 1 (Days 1-14) and Period 2 (Days 15-28) assessments; like arms were combined and then averaged. There were 3 visits: Visit 1 (Begin Period 1) Screening and Randomized assignment, Visit 2 (first day of Period 2) Cross over to other assignment, Visit 3 End of Study.

  • Subject or Caregiver Reported Perception of Ease of Administration as Recorded Weekly on a 5-point Scale. [ Time Frame: 28 Days; end of Period 1(14 days) and end of Period 2 (14 days) ] [ Designated as safety issue: No ]
    The difference in subject-reported overall satisfaction between the two injection methods as recorded on a 5-point scale following the end of each period of the study. The overall satisfaction was to be rated by the subject on a 5-point scale as 1 (Really Unhappy) to 5 (Really Happy), a higher score denoting greater satisfaction. Overall satisfaction is obtained only once at the end of each period; Period 1 Tjet group was added to Period 2 Tjet group and Period 1 syringe group was added to Period 2 syringe group; no averaging was necessary.

  • Subject-reported Overall Satisfaction Following the End of Each Period of the Study. [ Time Frame: 28 Days; end of Period 1(14 days) and end of Period 2 (14 days) ] [ Designated as safety issue: No ]
    The difference in subject-reported overall satisfaction between the two injection methods as recorded on a 5-point scale following the end of each period of the study. The overall satisfaction was to be rated by the subject on a 5-point scale as 1 (Really Unhappy) to 5 (Really Happy), a higher score denoting greater satisfaction. Overall satisfaction is obtained only once at the end of each period; Period 1 Tjet group was added to Period 2 Tjet group and Period 1 syringe group was added to Period 2 syringe group; no averaging was necessary.

Detailed Description:

The primary efficacy endpoint was the difference in mean subject-reported injection anxiety between the two injection methods as recorded on a 5-point FIS immediately before administration. A higher score denoted greater anxiety.

The injection anxiety score was to be reported by the subject from a row of five faces with values ranging from 5 (the face with the most negative affect) to 1 (the face with the most positive affect).
