Eligibility

Recruits 66 paediatric patients.

Vulnerable Population
Participants are infants and young children (age 0 to 32 months); vulnerable population selected. Signed informed consent must be obtained from each participant’s parent(s) or legal guardian. For breastfeeding participants, the mother must be willing and able to discontinue treatment with a drug that can be harmful to the participant or stop nursing as required by the protocol.

Inclusion criteria

  • {"criterion_text":"- Diagnosis of ACH confirmed by genetic testing. If prospective participants had prior genetic testing, the diagnosis must be confirmed by a report from a certified laboratory, documenting the specific mutation."}
  • {"criterion_text":"- Age 0 to 32 months (2 years and 8 months) at screening."}
  • {"criterion_text":"- Signed informed consent, which must be obtained from each participant’s parent(s) or legal guardian."}
  • {"criterion_text":"- Parent(s)/Guardian(s) willing and able to attend all study visits and comply with all study requirements."}
  • {"criterion_text":"- Parent(s)/Guardian(s) willing and able to comply with the routine care of the study participants according to local guidance for the management of infants and young children with ACH."}
  • {"criterion_text":"- In breastfeeding infants/young children, the mother must be willing and able to discontinue treatment with a drug that can be harmful to the participant, as this could confound the assessment of safety (ie, risk of developing an ADR to medication exposure via breast milk) or could impact the PK of infigratinib (a noncomprehensive list of prohibited medications is included in Appendix 7 [Section 10.6]). If discontinuation of treatment is not possible, the mother must be willing and able to stop the nursing of the participant."}
  • {"criterion_text":"- Able to swallow age-appropriate oral medication."}
  • {"criterion_text":"- In participants <1 year old, be compliant with recommended vitamin D supplementation of 5-10 μg/day or higher (or as recommended by country specific guidelines)."}

Exclusion criteria

  • {"criterion_text":"- Gastroesophageal reflux disease requiring prolonged treatment (>1 week) with prohibited medications."}
  • {"criterion_text":"- History of fracture of a long bone or spine within 6 months prior to screening."}
  • {"criterion_text":"- Any other significant concurrent disease or condition that, in the view of the investigator and/or sponsor, would confound assessment of efficacy or safety of infigratinib and/or would require treatment with a prohibited medication, and/or would place the participant at high risk for poor treatment compliance or for failure to complete the study."}
  • {"criterion_text":"- Gestational age at birth <37 weeks and/or birth weight <2500 grams."}
  • {"criterion_text":"- Regular long-term (>3 weeks; more than twice/year) treatment with supraphysiologic doses of glucocorticoid therapy (ie, >15 mg/m2/day of hydrocortisone or equivalent) or treatment with glucocorticoids at anti-inflammatory doses (for over 3 weeks within 6 months of the screening visit. NOTE: Low-dose topical, inhaled, or intranasal corticosteroids are acceptable."}
  • {"criterion_text":"- Current evidence of endocrine alterations of calcium/phosphorus homeostasis, including serum calcium and/or phosphorus outside of the normal range for age at screening."}
  • {"criterion_text":"- Allergy or hypersensitivity to any components of the study drug."}
  • {"criterion_text":"- History or presence of ectopic tissue X (based on participant medical history)."}
  • {"criterion_text":"- History or presence of malignancy (based on participant medical history)."}
