简要总结
ACCEL2/3 is a Phase 2/3 study. The purpose of the Phase 2 portion of the study (ACCEL2/3) is to evaluate the efficacy and safety of infigratinib in children with hypochondroplasia (HCH) receiving infigratinib at one of two doses, who have completed at least 26 weeks of participation in QED-sponsored ACCEL (QBGJ398-004).
详细描述
ACCEL 2/3 is a Phase 2/3 study that comprises of 2 portions. The Phase 2 portion is an open-label, portion in children with HCH aged 5 to 11 years old followed by a Phase 3 portion which is double-blind, placebo-controlled in children with HCH aged >3 years old to <18 years old.

- •Participants are able to swallow oral medication.
- •Participants and parent(s), legal guardian(s), or caregiver(s) are willing and able to comply with study visits and study procedures.
- •Participants are ambulatory and able to stand without assistance. Sex and Contraceptive/Barrier Requirements
- •Negative pregnancy test in girls ≥10 years of age or girls of any age who have experienced menarche.
- •If sexually active, participants whether male or female, must be willing to use a highly effective method of contraception, as relevant, while taking study drug and for 1 month after the last dose of study drug.
- •Signed informed consent.
排除标准
- •Participants who have ACH or a short stature condition other than HCH.
- •Significant concurrent disease or condition that, in the view of the investigator and/or sponsor, would confound assessment of efficacy or safety of infigratinib.
- •Current evidence of clinically significant corneal or retinal disorder/keratopathy confirmed by ophthalmic examination.
- •Concurrent circumstance, disease, or condition that, in the view of the investigator and/or sponsor, would interfere with study participation or safety evaluations.
- •History and/or current evidence of extensive ectopic tissue calcification.
- •History of malignancy.
- •Having received or planning to receive treatment with any other investigational or approved product for the treatment of ACH, HCH, or short stature.
- •Regular long-term treatment (≥3 weeks) with supraphysiologic doses of glucocorticoid.
- •Previous limb-lengthening surgery at any time or planned/expected to have limb-lengthening or guided growth surgery while participating in the study.
- •Participants receiving medications which could increase serum phosphorus and/or calcium concentrations
