Summary

This trial tests a drug to help children and teens with achondroplasia. It's randomized, double-blind, and placebo-controlled.

Who is the study for?
This trial is for children and adolescents aged 3 to <18 with achondroplasia, who are still growing and have completed at least 26 weeks in the PROPEL study. They must be able to swallow pills, stand without help, not be fully sexually mature, and girls of a certain age or menstruating must test negative for pregnancy.
What is being tested?
The trial tests Infigratinib against a placebo in participants with achondroplasia. It's a Phase 3 study where patients are randomly assigned to receive either the drug or an inactive substance (placebo), but neither they nor the doctors know which one they're getting.
What are the potential side effects?
Possible side effects of Infigratinib may include joint pain, gastrointestinal issues like nausea or diarrhea, liver problems indicated by blood tests changes, fatigue, and potential growth plate fusion affecting height.
