set variable [ACCESS::session data get "session.custom.variable"]
set newVariable [string trim $variable "@"]

Keep in mind this will remove all @ from $variable, regardless of location in the string.

Or I suppose you could just

set variable [string trim [ACCESS::session data get "session.custom.variable"] "@"]

Ekalieido,

This looks like it would work great, but it turns out the APM option that Kai suggested works better with my existing variable assign so I marked his response as the acceptable answer for my case. Unfortunately I can't mark both of you as correct, but for anyone else reading this looking for a similar solution please keep in mind that both of these answers are great suggestions.
