So, Larotrectinib is like a special kind of medicine that targets something called TRKs, which are like little protein switches in the body. These switches are TRKA, TRKB, and TRKC. And these TRKs? They’re kind of like the bad guys in cancer; they help it grow and spread.
It’s used to treat cancer that’s grown or spread, especially in solid tumors that have these fusion genes. It works for people of any age who have that kind of cancer with the NTRK fusion thing. You can take it as capsules, either 25 mg or a stronger 100 mg version, or in a liquid form, 20 mg per teaspoon.
For grown-ups, they usually say 100 mg, twice a day. For kids, it’s based on how big they are. It comes in bottles with 60 capsules each.
