Phase 3 Clinical Trial Evaluating the Efficacy and Safety of Navepegritide and Lonapegsomatropin in Achondroplasia (cAtCH)
A Phase 3, Randomized, Double-blind, Active Controlled, Multi-center Trial Investigating the Efficacy and Safety of Dual Therapy With Once-weekly Navepegritide and Once-weekly Lonapegsomatropin Compared to Navepegritide Monotherapy and Lonapegsomatropin Monotherapy in Children and Adolescents With Achondroplasia
This pivotal trial is being conducted to evaluate the efficacy, safety and tolerability of dual therapy with navepegritide and lonapegsomatropin administered as separate subcutaneous (SC) injections once weekly in children with achondroplasia (ACH) aged 2 to 17 years.
