Infigratinib low dose therapy is an effective strategy to treat hypochondroplasia.

ABSTRACT: Hypochondroplasia is a rare genetic form of skeletal dysplasia, caused by gain-of-function pathogenic variants in the FGF receptor 3 (FGFR3). It is characterized by disproportionate short stature and has a wide spectrum of clinical features. Currently, there are no precision therapeutic options approved for hypochondroplasia. Infigratinib is an orally bioavailable FGFR1-3 selective tyrosine kinase inhibitor in development for achondroplasia and hypochondroplasia. Infigratinib acts directly at the source of the pathophysiological cause of both conditions by inhibiting the phosphorylation of FGFR3 and attenuating both main downstream signaling pathways that are involved in the conditions. Results from a phase 2 study support the concept that infigratinib has a potential to improve bone growt
