Key exclusion criteria
Medical Conditions

1. Subjects who have hypochondroplasia or short stature condition other than ACH.
2. Significant concurrent disease or condition that, in the view of the investigator and/or sponsor, would confound assessment of efficacy or safety of infigratinib.
3. Current evidence of clinically significant corneal or retinal disorder/keratopathy -confirmed by ophthalmic examination.
4. Concurrent circumstance, disease or condition that, in the view of the investigator and/or sponsor, would interfere with study participation or safety evaluations and/or would require treatment with a prohibited medication, and/or would place the subject at high risk for poor treatment compliance or for not completing the study.
5. History and/or current evidence of extensive ectopic tissue calcification.
6. History of malignancy.

Prior/Concomitant Therapy
7. Having received or planning to receive treatment with any other investigational or approved product for the treatment of ACH or short stature.
8. Regular long-term treatment (=3 weeks) with supraphysiologic doses of glucocorticoid therapy (ie, >15 mg/m2/day of hydrocortisone or equivalent) or treatment with glucocorticoids at anti-inflammatory doses (ie, 2.5-10 mg/kg/day of hydrocortisone or equivalent) for over 3 weeks within 6 months of the screening visit (low-dose local preparations including inhaled steroid for asthma, intranasal sprays for allergies, and topical steroids are allowed).
9. Previous limb-lengthening surgery at any time or planned/expected to have limb-lengthening surgery or guided growth surgery during the study period. Guided growth surgery with plates removed at least 12 months prior to screening is allowed.
10. Currently receiving treatment with agents that are known strong inducers or inhibitors of CYP3A4 or prolonged treatment (>1 week) with medications that alter the pH of the gastrointestinal tract including antacids, H2 antagonists (eg, ranitidine, famotidine), and proton-pump inhibitors (eg, omeprazole).
11. Current evidence of endocrine alterations of calcium/phosphorus homeostasis.

Diagnostic assessments
12. Subjects who have significant abnormality in screening laboratory results.

Other Exclusions
13. Having had a fracture of the long bones (ie, extremities) or spine within 12 months prior to screening.
14. Pregnant or breastfeeding at the screening visit or planning to become pregnant (self or partner) at any time during the study.
15. Allergy or hypersensitivity to any components of the study drug.
