주간 로나페그소마트로핀과 일일 소마트로핀의 성장 호르몬 충분성 장애로 인한 저신장 또는 성장 부진을 겪는 소아 및 청소년에서의 효능과 안전성을 비교하는 시험

2026년 9월 29일 업데이트: Ascendis Pharma A/S

성장 호르몬 충분성 장애(터너 증후군, SHOX 결핍, 태아기 발육 부진, 특발성 저신장)로 인한 성장 장애 또는 저신장을 가진 사춘기 전 아동 및 청소년을 대상으로 주 1회 투여되는 로나페그소마트로핀과 일일 투여되는 소마트로핀의 효능 및 안전성을 비교하는 핵심적, 병렬 군, 3상, 개방형, 능동 대조군, 글로벌, 다기관, 무작위 바스켓 시험

This basket trial will enroll prepubertal children and adolescents with clinically diagnosed and genetically confirmed (if applicable) TS, SHOX-D, SGA, or ISS between ages of ≥2 and <18 years with open growth plates. The purpose of the study is to see how well treatment with once-weekly lonapegsomatropin works compared to treatment with daily somatropin. Approximately 186 participants will be distributed equally (1:1), to receive either lonapegsomatropin for 2 years or somatropin for 1 year followed by lonapegsomatropin for 1 year. This trial will be conducted in the United States, France, Germany, Italy, Romania, Spain and South Korea.

Exclusion Criteria:

  1. Advanced bone age X-ray by central reading defined as >20% above chronological age in months (Greulich 1959).

  4. Any diagnosis or presence at screening of the following:

    1. Untreated moderate or severe sleep apnea as determined by formal (local) read of an inpatient or at-home sleep study.
    2. Prader Willi syndrome with severe obesity, history of severe upper airway obstruction, or severe respiratory impairment.
  5. Signs/symptoms of intracranial hypertension, active proliferative retinopathy.

  6. Uncontrolled hypo- or hyperthyroidism.

  7. Uncontrolled diabetes mellitus (defined as: HbA1c >7.5% from central laboratory at screening).

  8. Known history or diagnosis of any gastrointestinal inflammatory condition, HIV, radiation exposure, other skeletal dysplasias, growth hormone deficiency, and/or cardio-thoracic surgery due to their independent effects on growth.

  9. Any significant hepatic or renal abnormality, such as abnormal renal function (defined as eGFR <60 mL/min/1.73m2).

  10. Undiagnosed or uncontrolled hypertension.

  11. Receiving treatment with any agent that might influence growth or interfere with GH secretion or action including any sex steroids and stimulants for attention-deficit/hyperactivity disorder (ADHD).

  12. High dose inhaled glucocorticoid for more than 28 consecutive days total over the course of 12 months.

  13. Female who is pregnant, plans to be pregnant, or breastfeeding.

  14. Participation in another interventional clinical trial involving an investigational compound within 90 days prior to screening or in parallel to this trial.

  15. Any disease or condition that, in the judgement of the investigator, may make the participant unlikely to comply with the requirements of the protocol or any condition that presents undue risk from the investigational product or trial procedures.

  16. Exclusion Criteria only applicable to TS:

    1. Presence of Y chromosome material on genetic testing without history of gonadectomy.
    2. Less than 10% of 45,X mosaicism.
    3. Any known, clinically significant, congenital or acquired cardiovascular dysfunction that might interfere with growth.
  17. Exclusion Criteria only applicable to SGA:

    a. Any known clinically significant abnormality likely to affect growth or the ability to evaluate growth with standing height measurements: (i.)Chromosomal aneuploidy, significant gene mutations, or medical syndromes with short stature, including but not limited to Turner syndrome, Laron syndrome, Noonan syndrome, Prader-Willi syndrome, abnormal SHOX-1 gene analysis or absence of GH receptors.

    (ii.)Congenital abnormalities (causing skeletal abnormalities), including but not limited to skeletal dysplasias.

  18. Exclusion Criteria only applicable to ISS:

    1. Known history of any condition that causes disproportionate short stature (i.e. skeletal dysplasias), chromosomal aneuploidy, significant gene mutations, or medical syndromes with short stature, including but not limited to Turner syndrome, Laron syndrome, Noonan syndrome, Prader-Willi syndrome, abnormal SHOX-1 gene analysis or absence of gH receptors.
