Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Infigratinib
Treatment: Drugs - Infigratinib

Experimental: Arm 1: Rollover subjects - Children who have completed QED-sponsored interventional study with infigratinib (Phase 2 or Phase 3)

Experimental: Arm 2: Treatment naïve subjects - Children naïve to infigratinib


Treatment: Drugs: Infigratinib
Infigratinib minitablets or sprinkle capsules to be administered by mouth. In subjects that completed a prior study with infigratinib, the starting dose will be the same as the last dose received in the prior interventional study with infigratinib. Infigratinib dose may be adjusted to 0.25 mg/kg/day (the dose selected to be explored further in the dose escalation portion of Phase 2 study QBGJ398-201 (PROPEL 2)).

Treatment: Drugs: Infigratinib
Infigratinib sprinkle capsules to be administered by mouth. Starting dose for the subjects naïve to Infigratinib will be 0.25 mg/kg/day (the dose selected to be explored further in the dose escalation portion of Phase 2 study QBGJ398-201 (PROPEL 2)).
