Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Description

Inclusion Criteria:

  • Patients who are on treatment with SKYTROFA (lonapegsomatropin)
  • Patients being clinically managed in USA
  • Patients with an appropriate written informed consent/assent as applicable for the age of the patient

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Assess the safety of patients treated with SKYTROFA (Lonapegsomatropin)
Time Frame: 5 years
Incidence of Adverse Events and Serious Adverse Events
5 years
Assess the effectiveness of patients treated with SKYTROFA (Lonapegsomatropin)
Time Frame: 5 years
Near adult height (cm)
5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assess clinical outcome assessments (COAs)
Time Frame: 5 years
Change in Quality of Life in Short Stature Youth (QoLISSY) scores from baseline through End of Study (QOLISSY scores range on a scale of 0 to 100 with higher scores representing better quality of life. (For both child and parent version))
5 years
Assess clinical outcome assessments (COAs)
Time Frame: 5 years
Change in Treatment Satisfaction Questionnaire for Medicine (TSQM-9) scores from baseline through End of Study (The TSQM-9 domain scores range from 0 to 100 with higher scores representing higher satisfaction on that domain)

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
