Primary Outcome(s)
|
Primary end point(s): The first primary endpoint of this trial is defined as the change in the average pain intensity core during the last 3 days (numerical rating scale [NRS]-3 pain intensity scores) from the Randomization Visit to the end of continuation (Final Evaluation Visit, 12 weeks after the Randomization Visit). The second primary endpoint will be the change in the patient assessment of constipation symptoms (PAC-SYM) total score from the Randomization Visit to the end of continuation (Final Evaluation Visit, 12 weeks after the Randomization Visit).
|
Main Objective: The primary objective is to evaluate the effectiveness, safety, and tolerability of tapentadol PR versus oxycodone/naloxone PR in non-opioid pre-treated subjects with uncontrolled severe chronic low back pain with a neuropathic pain component.
|
Secondary Objective: • To evaluate and compare tolerability profiles of tapentadol PR versus oxycodone/naloxone PR during the titration period and throughout the trial with a focus on gastrointestinal and central nervous system-related tolerability. • To evaluate the impact of tapentadol PR and oxycodone/naloxone PR on neuropathic pain-related symptoms. • To compare the impact on function and quality of life parameters between tapentadol PR and oxycodone/naloxone PR in subjects with severe chronic low back pain. • To compare effectiveness in terms of reduction of pain intensity between tapentadol PR and oxycodone/naloxone PR during titration as well as throughout the entire treatment period in the trial. • To investigate the impact of tapentadol PR versus oxycodone/naloxone PR on serum levels of sexual hormones
