What is the regular expression in notepad++ to remove a column?

Question

Notepad++

There is a table with 3 columns of the form joxi.ru/RmzL8L4cYyXGaA
for many lines,
from it in notepad ++ you need to remove the last column (where the comments are written in Cyrillic) from each line,
what regular expression should I use for this? At me while it turns out to delete only 2 and 3 columns together.
