A Study to Evaluate Growth in Participants Treated With Somatropin (Nutropin) Using NuSpin Device

Study Overview
=================
Brief Summary
-----------------
This is a Phase IV, open label, case-controlled, observational study to evaluate the age-adjusted cumulative height velocity in pre-pubertal isolated growth hormone deficient (IGHD) and idiopathic short stature (ISS) participants receiving daily doses of somatropin (recombinant human growth hormone [rhGH]; Nutropin) using NuSpin device compared to historical controls from the national cooperative growth study (NCGS).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Cohort 1: IGHD participants<br>Isolated growth hormone deficient (IGHD) participants who initiated somatropin (Deoxyribonucleic acid [DNA] origin) (recombinant human growth hormone [rhGH]) using the NuSpin device, will be observed for at least 2 years.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Annualized Height Velocity in Response to rhGH Treatment Using the NuSpin Device After Two Years of Treatment | The annualized height velocity (cm per year [cm/yr]) over 2 years was calculated as: [(height in cm at t24 minus (-) height in cm at t0) divided by (date at t24 - date at t0)] multiplied by 365.25, where, t0 is the baseline measurement visit and t24 is the 2-year measurement visit. | Baseline up to Month 24 (Year 2) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Annualized Height Velocity in Response to rhGH Treatment Using the NuSpin Device for First Year of Treatment | The annualized height velocity (cm/yr) after 1 year was calculated as: [(height in cm at t12 - height in cm at t0) divided by (date at t12 - date at t0)] multiplied by 365.25, where, t0 is the baseline measurement visit and t12 is the 1-year measurement visit. | Baseline up to Month 12 (Year 1) | 
| Annualized Height Velocity in Response to rhGH Treatment Using the NuSpin Device During the Second Year of Therapy | The annualized height velocity (cm/yr) for second year was calculated as: [(height in cm at t24 - height in cm at t12) divided by (date at t24 - date at t12)] multiplied by 365.25, where, t12 is the 1-year measurement visit and t24 is the 2-year measurement visit. | Month 12 to Month 24 (Year 1 to Year 2) |
