A Safety and Effectiveness Study of Prolonged Release Tapentadol Hydrochloride Among Filipino Patients With Moderate to Severe Chronic Non-Cancer Pain

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the safety and effectiveness of prolonged release tapentadol hydrochloride for the relief of moderate to severe chronic non-cancer pain among Filipino patients.

Detailed Description
-----------------
This is an open-label (all people know the identity of the intervention), multi-center (study conducted at multiple sites), observational study (study in which the investigators/ physicians observe the patients and measure their outcomes). The study will enroll approximately 100 patients who will be taking prolonged release tapentadol hydrochloride with a dosing regimen stipulated in the product insert. As this is an observational study, assessment of patient will be based on the accepted clinical practice in the Philippines. Patients will be monitored at baseline (Day 1) and throughout the 84-day treatment period of prolonged release tapentadol hydrochloride (every 7 days for the first two weeks, and thereafter every 28 days for the next three months) for effectiveness with the help of short form Brief Pain Inventory (BPI) questionnaire. Safety evaluations will include assessment of adverse events, clinical laboratory tests, and co-morbid conditions. The total study will be conducted for 3 years and the duration of treatment will be for 84 days.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of patients with incidence of adverse events and adverse drug reactions |  | From the date of first exposure of patient to the study medication until 30 days after the last dose of the study medication and at anytime the investigator deems it as necessary, as assessed for 3 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The short form Brief Pain Inventory (BPI) questionnaire scores | The short form BPI allows patients to rate the severity of their pain on a scale of 0 (no pain) to 10 (pain as bad as you can imagine) and the degree to which their pain interferes with common dimensions of feeling and function (general activity, walking, work, mood, enjoyment of life, relations with others, and sleep) on a scale of 0 (no interference) to 10 (interferes completely). | Baseline (Day 1), Day 7, Day 14 and Day 28, Day 56, and Day 84 |
