COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Infigratinib 0.016 mg/kg
Treatment: Drugs - Infigratinib 0.032 mg/kg
Treatment: Drugs - Infigratinib 0.064 mg/kg
Treatment: Drugs - Infigratinib 0.128 mg/kg

Experimental: Infigratinib 0.016 mg/kg - Dose Escalation:
Infigratinib is provided as minitablets in 2 strengths: 0.1 mg and 1 mg for daily oral administration. The dose and number of minitablets/day will be calculated based on individual participant weight. Doses will be adjusted based on weight changes approximately every 3 months.

Experimental: Infigratinib 0.032 mg/kg - Dose Escalation:
Infigratinib is provided as minitablets in 2 strengths: 0.1 mg and 1 mg for daily oral administration. The dose and number of minitablets/day will be calculated based on individual participant weight. Doses will be adjusted based on weight changes approximately every 3 months.

Experimental: Infigratinib 0.064 mg/kg - Dose Escalation:
Infigratinib is provided as minitablets in 2 strengths: 0.1 mg and 1 mg for daily oral administration. The dose and number of minitablets/day will be calculated based on individual participant weight. Doses will be adjusted based on weight changes approximately every 3 months.

Experimental: Infigratinib 0.128 mg/kg - Dose Escalation:
Infigratinib is provided as minitablets in 2 strengths: 0.1 mg and 1 mg for daily oral administration. The dose and number of minitablets/day will be calculated based on individual participant weight. Doses will be adjusted based on weight changes approximately every 3 months.
Dose Expansion:
Upon identification of the recommended dose from all cohorts analyzed, an expansion cohort of 20 subjects may begin enrollment to further determine safety, tolerability, efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) of the selected dose.

Summary
Brief summary
This is a Phase 2, multicenter, open-label, dose-escalation and dose-expansion study to

receptor (FGFR) 1-3-selective tyrosine kinase inhibitor, in children 3 to 11 years of age
with Achondroplasia (ACH) who previously participated in the PROPEL study (Protocol
QBGJ398-001) for at least 6 months. The study includes dose escalation with extended
treatment, and dose expansion.
