Hemlibra funding under Trump

Hi all. My son has severe hemophilia A and takes Hemlibra every month, like many here. It has been a godsend in more ways than one for him and I fear how we would navigate his disease as easily without it. Me and my wife are both employed in healthcare, and through a combination of private health insurance and some sort of grant through Genentech, we miraculously have $0 copay to receive this medication.

With Trump and his administration posturing as if they will gut much of federal funding for a variety of things people depend on, I am extremely worried there will come a day that we will go to pick up the medication and be asked to pay the insane ~$10,000+ cost that I have heard about. Does anyone have any insight, guidance, or words of experience on this situation?
