Remove prefix with unknown characters in JavaScript

I have a web page that the title is changed from 'Pagename' to '(1) Pagename' when there is an update on the page. That number increments to 50 each time there is a new update and then is maxed out showing '(50+) Timeline'.

When logging page views, Google Analytics shows the '(n) Pagename', which I don't want. So I found out how to manually change to logged page title, _gaq.push(["_set", "title", 'new title']);.

So my question is, how do I most efficiently remove the (1-50)/(50+) prefix and just get 'Pagename'? Is regex best for this?

This is what I'm using based on the answer from Ross:

var window_title = window.title.replace(/^\(\d+\+?\)\s/, '');
_gaq.push(["_set", "title", window_title]);

Yes, RegEx can do that.

window.title.replace(/^\(\d+\+?\)\s/, '');

Of course it depends on what software your site is using as perhaps it would be possible to just output the page title without that prefix in the relevant part of the template. So echoing that directly into the Google Analytics tag. But I think the above javascript is probably the easier solution to implement.
