About this trial

This is an interventional treatment trial for Osteochondrodysplasia

Eligibility Criteria

0 Days - 12 Years (Child)All SexesDoes not accept healthy volunteers

Inclusion Criteria: Participants must have ACH with a confirmed mutation in the FGFR3 gene Participants and/or parent(s) or legal representative(s) must be willing and able to perform all the study procedures to the best of their physical ability. Parent(s) or legal representative(s) capable of giving signed informed consent and participants capable of giving assent when applicable. Exclusion Criteria: Have hypochondroplasia (or the N540K mutation) or short stature condition other than ACH (eg, trisomy 21, pseudochondroplasia) Participants have received any dose of medications or investigational product, including human growth hormone, intended to affect participants' stature or body proportions within 6 months of enrollment (Week 0/Day 1/Visit 2). Have a history of growth plate closure. Long bone fracture within 3 months of enrollment (Week 0/Day 1/Visit 2) Current evidence of corneal or retinal disorder/keratopathy. Participants have had a previous surgical intervention involving the foramen magnum (Stage 2 only). Hyperphosphatemia. The above information is not intended to contain all considerations relevant to a potential participation in a clinical trial.
