8 Use in Specific Populations

8.4 Pediatric Use

Additions and/or revisions underlined:

The safety and effectiveness of IBRANCE in pediatric patients have not been established.

 

The safety and effectiveness of IBRANCE were assessed but not established in three trials: one open-label trial [A5481092, (NCT03709680)] that included 98 pediatric patients 2 to less than 17 years of age who received IBRANCE in combination with chemotherapy for recurrent or refractory solid tumors and two open-label trials that included 42 pediatric patients 4 to less than 17 years of age who received IBRANCE as a single agent for recurrent or refractory solid tumors [APEC1621I, (NCT03526250)] or primary central nervous system (CNS) tumors [PBTC-042, (NCT02255461)].


No new safety signals were observed in these trials. Palbociclib exposures in pediatric patients who received IBRANCE as a single agent or in combination were within range of those observed in adults given a similar dose based on body surface area.
