Summary:

      A 26 week trial of TransCon hGH, a long-acting growth hormone product, administered
      once-a-week. Approximately 150 children (males and females) with growth hormone deficiency
      (GHD) will be included. All study participants will receive TransCon hGH. This is a global
      trial that will be conducted in, but not limited to, the United States, Canada, Australia,
      and New Zealand.
    

Eligibility criteria:

        Inclusion Criteria:

               2. If ≥ 6 months but < 3 years old, are either hGH treatment-naïve or are taking
                  daily hGH at a dose of ≥ 0.20mg hGH/kg/week for no more than 130 weeks prior to

          3. Tanner stage < 5 at Visit 1

          4. Open epiphyses (bone age ≤14.0 years for females or ≤16.0 years for males)

          5. Written, signed, informed consent of the parent or legal guardian of the subject and
             written assent of the subject as required by the IRB/HREC/IEC

          3. History of malignant disease

          4. Any clinically significant abnormality likely to affect growth or the ability to
             evaluate growth (eg, chronic diseases or conditions such as renal insufficiency,
             spinal cord irradiation, hypothyroidism, active celiac disease, malnutrition or
             psychosocial dwarfism)
