Previous examination of the relationship between fremanezumab exposures and baseline body weight supports a weight cutoff of 45 kg of pediatric dose selection, with the approved adult dose of 225 mg monthly being appropriate or patients weighing >= 45 kg

As part of the pediatric phase 3 program for fremanezumab, the present analyses were conducted to determine the appropriate dose for migraine pediatric patients weighing <45 kg.

These analyses included a refinement of the adult fremanezumab population pharmacokinetic (PopPK) model using pediatric PK data from teh phse 1 study (TV48125-CNS-10141) in migraine patients 6 to 11 years old and simulation
