Welcome to the group. My wife has been on Tabrecta since June and has had very good results, even her oncologist is very pleased. My wife started on Keytruda which worked for awhile then they gave her Chemo which but her in the hospital for 5 days. When her oncologist visited her in the hospital she said there was a brand new targeted drug called Tabrecta she was going to try to get her on. Within a few days she was on it. See if your Dr. or yourself can get you on a program to help with the cost as it is very expensive.
