What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary objective is to investigate changes in height Standard Deviation Score (SDS)

    Measured: in response to 12 months Norditropin® treatment in children with PWS (referenced to PWS population

Secondary outcomes (8)
  1. Changes in height SDS from start of treatment to last observation during Norditropin treatment (referenced to PWS population1)

    Measured: at 12 months- and at last observation during Norditropin treatment

  2. Change in body composition (DEXA, Bio impedance or stable isotope dilution)

    Measured: at 12 months- and at last observation during Norditropin treatment

  3. Height velocity (HV) and change in HV

    Measured: at 12 months- and at last observation during Norditropin treatment

  4. Glycated Fraction of Haemoglobin (HbA1c)

    Measured: at 12 months- and at last observation during Norditropin treatment

  5. Insulin-Like Growth Factor-I (IGF-I)

    Measured: at 12 months- and at last observation during Norditropin treatment

  6. Haematology

    Measured: at 12 months- and at last observation during Norditropin treatment

  7. Thyroid-stimulating hormone (TSH) and active form of free thyroxin

    Measured: at 12 months- and at last observation during Norditropin treatment

  8. Adverse Events.

    Measured: at 12 months- and at last observation during Norditropin treatment
