David was scheduled to get dose 4 of the Enhertu chemo today, but several of his white blood cell counts were still too low. So he received a shot of Filgrastim, a growth factor that stimulates the production, maturation, and activation of neutrophils (a type of white blood cell). He'll receive another shot of it tomorrow. Hopefully it will raise his blood counts enough that he can get Enhertu dose 4 on 9/16.
