This registry is a observational, single-center study designed to collect clinical data on patients with achondroplasia and hypochondroplasia.
Purpose of the study: The main purpose of this study is to determine the safety and evaluate the effect of a once weekly dose of TransCon CNP in prepubertal children with achondroplasia in China. Study Treatments: TransCon CNP is an investigational (new) drug, which means that it is currently being tested, and therefore is considered experimental. TransCon CNP is designed to provide a sustained exposure of active CNP by subcutaneous (under the skin) injection once weekly. The Randomized Period of this study is a double-blinded and placebo-controlled. "Placebo-controlled" means that some participants will receive injections that don't contain any TransCon CNP (placebo injection - no active ingredient). "Double-blinded" means that neither the participant nor the study doctor will know which treatment the participant will be receiving, except in an emergency. After completion of the Randomized Period the trial participant may be invited to take part of the Open-Label Period of this study. "Open-label" means that all participants will receive injections that contain TransCon CNP; regardless of which treatment (TransCon CNP or placebo) was assigned during the 52 weeks (1 year) Randomized Period/blinded treatment period. It also means that both the participant and the study doctor will know which treatment, and which dose the participant receives.
This is a Phase 2, multicenter, open-label, extension (OLE) study to evaluate the long-term safety, tolerability, and efficacy of infigratinib, an FGFR 1-3-selective tyrosine kinase inhibitor, in subjects with ACH who previously completed a QED-sponsored interventional study, and potentially in additional subjects who are naïve to infigratinib treatment. Quality of Life assessments for this subject population will also be evaluated. Treatment-naïve subjects must have at least a 6-month period of growth assessment in the PROPEL study (Protocol QBGJ398 001) and will be enrolled in this OLE study only after a dose to be explored further is identified in Phase 2 Study QBGJ398-201.
All participants who completed the prior study to assess long-term safety, tolerability, pharmacokinetics and efficacy, and in the opinion of the investigator, continue to have a positive risk:benefit profile, will be offered to enroll in this open-label extension (OLE) study for up to an additional 24 months of treatment. Approximately 63 participants will be offered to continue at the previously received dose of Recifercept either Low Dose Medium Dose High Dose or at the therapeutic dose once it is identified. Participants will attend the clinic monthly for 24 months. Assessments include safety, blood sampling, physical examination, vital signs, anthropometric body measurements & patient/caregiver quality of life questionnaires.
Approximately 63 participants will be randomized to one of three doses to receive Recifercept either - Low Dose - Medium Dose - High Dose Participants will will attend the clinic at baseline and at Day 1, 4, 8, 15, 29 & then Month 2, 3 6, 9 & 12. Assessments include safety, blood sampling, physical examination, vital signs, anthropometric body measurements & patient/caregiver quality of life questionnaires Participants will received treatment with Recifercept for 12 months. All participants who complete the study and in the opinion of the investigator, continue to have a positive risk:benefit profile, will be offered to enroll into an open-label extension (OLE) study. A PK cohort will include 12 participants who will randomly receive a single dose of 3 mg/kg of Phase 2 study (process 1c) formulation and a single dose of 3 mg/kg of the proposed Phase 3 (process 2) study formulation in a cross over study. Dose of the cohort could be changed due to emerging safety and efficacy data in the study.
Study 111-209 is a Phase 2 randomized, open-label clinical trial of BMN 111 in infants and young children with a diagnosis of Achondroplasia at a heightened risk of requiring cervicomedullary decompression surgery
This is a Phase 2, multicenter, open-label, dose-escalation and dose-expansion study to evaluate the safety, tolerability, and efficacy of infigratinib, a fibroblast growth factor receptor (FGFR) 1-3-selective tyrosine kinase inhibitor, in children 3 to 11 years of age with Achondroplasia (ACH) who previously participated in the PROPEL study (Protocol QBGJ398-001) for at least 6 months. The study includes dose escalation with extended treatment, and dose expansion. The study also includes a PK Substudy to fully characterize the pharmacokinetics of infigratinib in children with ACH.
Achondroplasia is a genetic disorder characterized by disproportionate short stature. It affects about 1 in 2500 live births in the world. The cause of Achondroplasia was identified to be a gain-of-function mutations in the fibroblast growth receptor 3 (FGFR3). In these children compression of the spinal cord at the foramen magnum stenosis can occur in early childhood which, can lead to central sleep apnea. It can lead to morbidity and mortality. A surgical intervention may be indicated in patients who present a foramen magnum stenosis. However, surgical indications are still under discussion. The objective of this retrospective study is to analyse the degree of stenosis and its clinical tolerance/evolution from radiological data monitored at the Hospital Femme Mère Enfant.
The trial is a multicenter, double-blind, randomized, placebo-controlled, dose escalation trial of weekly TransCon CNP administered subcutaneously in prepubertal children 2 to 10 years old, inclusive, with Achondroplasia.
