An Evaluation of the Effectiveness and Tolerability of Tapentadol Hydrochloride Prolonged Release, and Tapentadol Hydrochloride Immediate Release on Demand, in Subjects With Uncontrolled Severe Chronic Nociceptive, Mixed or Neuropathic Low Back Pain Taking Either WHO Step I or Step II Analgesics or no Regular Analgesics.
In Brief
A Phase 3 clinical trial evaluating Tapentadol PR and Observation period for Chronic Pain and Low Back Pain. Completed, enrolled 208 participants across 46 sites in 9 countries.
Detailed Summary
The main objective of the study is to evaluate the effectiveness, tolerability, and safety of tapentadol hydrochloride prolonged release in subjects suffering from severe chronic low back pain (LBP) who are taking either WHO Step I or Step II analgesics or no regular analgesics. This is a clinical effectiveness trial designed to establish a link between anticipated clinical outcomes and the clinical practice by means of selected measures of clinical and subject-reported outcome. The trial will compare the effectiveness of previous analgesic treatment (either WHO Step I or Step II analgesics or no regular analgesics) with that of tapentadol hydrochloride prolonged release (PR) treatment during defined periods of evaluation.

Interventions
Tapentadol Prolonged Release (PR) Titration and Optimal Dose Period: Starting at 50 mg Tapentadol PR twice daily, adjusted with 50 mg PR steps (upwards or downwards) as necessary to achieve a balance between pain relief and a satisfactory level of tolerability. Participants were not permitted to exceed a dose of 500 mg of Tapentadol per day.
Eligibility assessment period to characterize the baseline over a one week period (week -1). Participants continued their previous treatment prior to allocation to tapentadol, if eligible.
Maintenance Period: In this period participants continued Tapentadol Prolonged Release (PR) on the dose established in the Titration and Optimal Dose Period. Tapentadol IR participants were not permitted to exceed a total daily tapentadol dose of 500 mg.
