Study Summary
This trial is testing a new drug for children with achondroplasia, a condition that causes dwarfism. The drug is given weekly and the trial will compare it to a placebo to see if it is effective.
Who is the study for?
This trial is for prepubertal children aged 2-10 with Achondroplasia, able to stand without assistance and have a caregiver willing to give injections. Kids who've had growth treatments or need surgery that could interfere with the study can't join.Check my eligibility
What is being tested?
The trial tests TransCon CNP, given weekly via injection, against a placebo in kids with Achondroplasia. It's randomized and double-blind, meaning neither the researchers nor participants know who gets the real treatment.See study design
What are the potential side effects?
While specific side effects are not listed here, they may include reactions at the injection site, general discomfort or other issues related to growth treatments which will be monitored throughout the trial.

Research Highlights
Information in this section is not a recommendation. We encourage patients to speak with their healthcare team when evaluating any treatment decision.Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
TransCon CNP is a sustained release formulation of C-type Natriuretic Peptide (CNP), which promotes bone growth by inhibiting the signaling pathway of fibroblast growth factor receptor 3 (FGFR3). FGFR3 is overactive in Achondroplasia, leading to impaired bone growth and short stature.
By blocking this pathway, CNP helps to normalize bone growth and improve height outcomes in patients. This mechanism is crucial for Achondroplasia patients as it directly targets the underlying cause of their growth issues, offering a potential therapeutic approach to enhance their quality of life.
