It’s an ALK inhibitor for NSCLC that tests positive for ALK, you know? It stops that ALK stuff in its tracks. So, there are three doses: 30 mg, 90 mg, and 180 mg, all in the film-coated tablet kind.
You should kick things off with the 90 mg a day for the first week, then move on to the 180 mg daily. The stuff comes in bottles with 30 pills each.
