Primary Outcome Measures:

Number of Participants Who Experienced an Adverse Event (AE) [ Time Frame: baseline through 1 year ] [ Designated as safety issue: Yes ]
See the Reported Adverse Events section for details.

Secondary Outcome Measures:

Patient Global Impression of Improvement (PGI-I) Scale at One Year Endpoint. [ Time Frame: 1 year ] [ Designated as safety issue: No ]
A scale that measures the participant's perception of improvement at the time of assessment compared with the start of treatment. The score ranges from 1 (very much better) to 7 (very much worse).
Change From Baseline to One Year Endpoint for Patient Global Impression of Improvement (PGI-I) Scale [ Time Frame: baseline, 1 year ] [ Designated as safety issue: No ]
A scale that measures the participant's perception of improvement at the time of assessment compared with the start of treatment. The score ranges from 1 (very much better) to 7 (very much worse).
Brief Pain Inventory (BPI) Severity Scores at One Year Endpoint [ Time Frame: 1 year ] [ Designated as safety issue: No ]
A self-reported scale that measures the severity of pain. The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine). There are 4 questions assessing worst pain, least pain, and average pain in the past 24 hours, and the pain right now.
Change From Baseline to One Year Endpoint in Brief Pain Inventory (BPI) Severity Scores [ Time Frame: baseline, 1 year ] [ Designated as safety issue: No ]
A self-reported scale that measures the severity of pain. The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine). There are 4 questions assessing worst pain, least pain, and average pain in the past 24 hours, and the pain right now.
Brief Pain Inventory (BPI) Interference Scores at One Year Endpoint [ Time Frame: 1 year ] [ Designated as safety issue: No ]
Self-reported scale measures interference of pain on function in past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life. Scores range from 0 (does not interfere) to 10 (completely interferes). Average interference = self-reported scale measures interference of pain on average of 7 questions assessing interference of pain for general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life. Average interference scores range from 0 (does not interfere) to 10 (completely interferes).
Change From Baseline to One Year Endpoint in Brief Pain Inventory (BPI) Interference Scores [ Time Frame: baseline, 1 year ] [ Designated as safety issue: No ]
Self-reported scale measures interference of pain on function in past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life. Scores range from 0 (does not interfere) to 10 (completely interferes). Average interference = self-reported scale measures interference of pain on average of 7 questions assessing interference of pain for general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life. Average interference scores range from 0 (does not interfere) to 10 (completely interferes).
Beck Depression Inventory-II (BDI-II) Total Score at One Year Endpoint [ Time Frame: 1 year ] [ Designated as safety issue: No ]
A 21-item, participant-completed questionnaire to assess characteristics of depression. Each of the 21 items corresponding to a symptom of depression is summed to give a single score. There is a 4-point scale for each item ranging from 0 to 3. Total score of 0-13 is considered minimal range, 14-19 is mild, 20-28 is moderate, and 29-63 is severe.
Change From Baseline to One Year Endpoint in Beck Depression Inventory-II (BDI-II) Total Score [ Time Frame: baseline, 1 year ] [ Designated as safety issue: No ]
A 21-item, participant-completed questionnaire to assess characteristics of depression. Each of the 21 items corresponding to a symptom of depression is summed to give a single score. There is a 4-point scale for each item ranging from 0 to 3. Total score of 0-13 is considered minimal range, 14-19 is mild, 20-28 is moderate, and 29-63 is severe.
