In this particular situation I'd do it like this: C-space, C-a, 4x C-f, C-w 
(set mark, move to beginning of the line, move 4 characters forward, delete 
selection).
Or alternatively C-space, C-a, M-4 C-f, C-w (same thing but automate repetitive 
C-f).

Actually, you can use (setq org-special-ctrl-a/e t), then you can drop 4x C-f 
because C-a will take you to beginning of the heading automatically.

If you need to do this particular thing often you can make a macro out of it, 
or a small interactive function.

By the way, there's also C-0 C-k (kill to the beginning of the line), but that 
will also remove the heading asterisks, which is probably not intended.
