Description
Summary
This is a long-term, multicenter, non-interventional study of children ages 2.5 to <17 years with hypochondroplasia (HCH).
Official Title
Prospective Clinical Assessment Study in Children with Hypochondroplasia: ACCEL
Details
The objective is to evaluate growth, HCH-related medical complications, health-related quality of life, functional abilities and cognitive functions of study participants. Data collected will contribute to the characterization of the natural history of children with HCH. No study medication will be administered.

Eligibility
You can join if…
Open to people ages 30 months to 16 years
Signed informed consent.
Aged 2.5 to <17 years at study entry.

Have ACH or short stature condition other than HCH.
In females, having had their menarche. Annualized height growth velocity ≤1.5 cm/year over a period ≥6 months prior to screening.
Having a clinically significant disease or condition that in view of the investigator or Sponsor will interfere with the evaluation of growth, with study participation or not be in the best interest of the participant.
Clinically significant abnormality in any laboratory test result at screening
Have been treated with growth hormone, IGF 1, or anabolic steroids the previous 6 months or long-term treatment (>3 months) at any time.
Current evidence of corneal or retinal disorders.
Have used any other investigational product or investigational medical device for the treatment of HCH or short stature.
Have had regular long-term treatment (>1 month) with oral corticosteroids (low-dose ongoing inhaled steroid for asthma is acceptable).
Previous limb-lengthening surgery or guided growth surgery with plates still in place or removed within the 6 months prior to screening.
Having had a fracture of the long bones or spine within 12 months of screening.
History and/or current evidence of extensive ectopic tissue calcification.
History of malignancy.
Concurrent circumstance, disease, or condition that, in the view of the investigator and/or sponsor, would interfere with study participation, and/or would place the participant at high risk for poor compliance with study activities or for not completing the study.
