evaluate the efficacy and safety of actiq in patients with cancer and breakthrough pain

Conditions: Breakthrough Pain

Summary: the primary objective of the study is to determine whether a test titration regimen of actiq treatment will reduce the number of inadequately managed episodes of breakthrough pain for an individual patient by attaining a successful dose of actiq treatment more quickly. the successful actiq dose provides a satisfactory combination of efficacy and tolerability after a single administration, as assessed by the patient.
