How will you manage change request in Agile?

via backlog refinement

In the same way you manage a change request using any type of approach: by running the defined change management process. Some people think that using Agile approach the initiative will accept changes at any time in the life cycle and no change management process will run to evaluate it. That is not right, including each method based on Agile practice has a change management process defined on it, sometimes implicit, The reason because in the new PMBOK (just in case you follow the PMI way to manage project) the work "project" was added to most of the items is because things like change management must be derived for corporate policies.
