A Study to Compare the Experiences of Taking Daily Growth Hormone Injections to Weekly Ngenla in Children With Low Levels of Growth Hormone
- Conditions
- Pediatric Growth Hormone Deficiency
- Interventions
- Device: Sharps bin to collect used needles/injections
- Registration Number
- NCT06113952
- Lead Sponsor
- Pfizer
- Brief Summary
The purpose of this study is to learn about:
* how children stick to taking their injections
* their experience with the study medicines (Ngenla and daily growth hormone) prescribed to children with low levels of growth hormone.
This study is seeking participants who:
* are being treated or are ready to start treatment with daily growth hormone or Ngenla.
* use a sharps bin to collect used needles.
The study medicines will be given as per regular care agreed with the doctor. The study will compare participant experiences to help us see:
- the difference in how the participants stick to taking their daily growth hormone injections compared to participants using once weekly Ngenla.
Participants will take part in this study for up to 14 months. During this time, they will have 3 study visits at the study clinic. The participants will use the HealthBeacon™ smart sharps bin for collecting the used needles or injections.
- Detailed Description
This multicenter, international, longitudinal, prospective, site-based, low-interventional study aims to evaluate and monitor treatment experience, defined by treatment adherence and persistence, in children aged 3-16 years old with a diagnosis of pediatric growth hormone deficiency (pGHD), receiving either daily growth hormone (dGH) treatment or once weekly Ngenla. The study is planned to be conducted in a total of 50 participating sites distributed across Belgium, Canada, France, Italy, Luxembourg, Spain, UK, and US.
Data on treatment adherence and persistence will be collected in real-time over a period of 12 months using the HealthBeacon™ Smart Sharps Bin™ as a treatment monitoring device.
Additional data, including demographic and clinical characteristics, will be collected at three timepoints, in line with the routine care in each participating site and/or country, over a maximum period of 14 months.
Approximately 400 participants will be enrolled in the study (approximately 200 participants prescribed dGH injections and approximately 200 prescribed Ngenla).

Group Intervention Description Patients treated with daily growth hormone Sharps bin to collect used needles/injections Approximately 200 children with a diagnosis of pGHD who are treatment naive or currently receiving daily GH injections will be enrolled Patients treated with weekly growth hormone Sharps bin to collect used needles/injections Approximately 200 children with a diagnosis of pGHD who are treatment naïve or currently receiving once weekly Ngenla will be enrolled.
- Primary Outcome Measures
Name Time Method Mean Adherence To Ngenla and daily growth hormone 12 months The adherence for Ngenla and daily growth hormone followed the medication possession ratio definition(MPR). The MPR is calculated from the total number of injections used and collected in the Smart Sharps Bin™ .
- Secondary Outcome Measures
Name Time Method Change from baseline in Life Interference Questionnaire-Growth Hormone Deficiency I (LIQ-GHD I) questionnaire 12 months The LIQ-GHD I instrument uses either a 5 point scale from never to always or very easy to very difficult or a 7 point scale from extremely convenient to extremely inconvenient.
It contains the following subscales:
* Pen ease of use
* Ease of the injection schedule
* Satisfaction with overall treatment experience
* Willingness to continue injection schedule
* Patient life interference
* Number of missed injections during the past 4 weeks(two questions asking for number of missed injections and reasons)
* Caregiver life interferencePercentage of scheduled injections taken per participant 12 months The percentage of scheduled injections taken per participant is calculated as the proportion of actual number of injections with Ngenla or daily growth hormone used from the total number of expected injections.
Mean Adherence To Ngenla and daily growth hormone for switch participants 12 months - Switch participants: dGH to Ngenla and vice versa The adherence for Ngenla and daily growth hormone follows the medication possession ratio definition(MPR). The MPR is calculated from the total number of injections used and collected in the Smart Sharps Bin™ .
Mean Adherence To Ngenla and daily growth hormone for naive/non-naive subgroups. 12 months - Treatment naïve vs non-naïve (either dGH or Ngenla) The adherence for Ngenla and daily growth hormone follows the medication possession ratio definition(MPR). The MPR is calculated from the total number of injections used and collected in the Smart Sharps Bin™ .
Percent of participants who discontinued Ngenla or daily growth hormone 12 months Persistency/discontinuation is evaluated at specific time windows, after patients stop utilizing the sharps bin.
Number of participants who switch growth hormone treatment 12 months Number of participants who switch from daily to weekly GH injections or from weekly to daily GH injections is reported.
Percentage of participants who switch growth hormone treatment 12 months Percentage of participants who switch from daily to weekly GH injections or from weekly to daily GH injections is reported.
Change from baseline in Quality of Life in Short Stature Youth (QoLISSY) questionnaire for patients and for caregivers 12 months The QoLISSY questionnaire is a 5 point scale from not at all/never to extremely/always.
It evaluates the following health related quality of life domains for participants and their caregivers:
* Physical impact of height
* Social impact of height
* Emotional impact of heightChange from baseline in effectiveness evaluations for Ngenla and daily growth hormone 12 month Height in cm, weight in kg, and BMI in kg/m2 at diagnosis and follow-up visits and annualized height velocity in cm.
Number of participants who discontinued Ngenla or daily growth hormone 12 months Persistency/discontinuation is evaluated at specific time windows, after patients stop utilizing the sharps bin.
Healthcare practitioner (HCP) preference survey 12 months HCP preference and satisfaction survey for treatment regimen and treatment experience (daily or weekly injections or no preference) and satisfaction rated from very satisfied to very dissatisfied.
Presence or absence of factors influencing adherence 12 months Lifestyle factors are assessed:
* travel, illness, overnight sleep
* injection administration by caregiver/nurse or self-administration Number of concomitant medications and route of administration are collectedMean Adherence To Ngenla and daily growth hormone for age subgroups. 12 months -Different age groups: 3-7 years/8-11 years/12-16 years The adherence for Ngenla and daily growth hormone follows the medication possession ratio definition(MPR). The MPR is calculated from the total number of injections used and collected in the Smart Sharps Bin™ .
