QED Therapeutics, a BridgeBio company
This is a Phase 2, multicenter, open-label, extension (OLE) study to evaluate the long-term safety, tolerability, and efficacy of infigratinib, an FGFR 1-3-selective tyrosine kinase inhibitor, in subjects with ACH who previously completed a QED-sponsored interventional study, and potentially in additional subjects who are naïve to infigratinib treatment. Quality of Life assessments for this subject population will also be evaluated. Treatment-naïve subjects must have at least a 6-month period of growth assessment in study QBGJ398-001 (PROPEL) and will be enrolled in this OLE study only after a dose to be explored further is identified in Phase 2 Study QBGJ398-201 and subjects are not otherwise eligible to enroll in another QED-sponsored Phase 2 or Phase 3 ACH study.
Key Rollover Subjects Inclusion Criteria: 1. Pediatric subjects with ACH who have completed a previous QED-sponsored interventional study with infigratinib. 2. Subjects and parent(s), legal guardian(s), or caregiver(s) are willing and able to comply with study visits and study procedures. 3. Subjects are able to swallow oral medication. 4. Negative pregnancy test in girls ≥10 years of age or girls of any age who have experienced menarche. 5. If sexually active, subject must be willing to use a highly effective method of contraception while taking study drug and for 1 month after the last dose…
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)).
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)).
