NEP-TUNE: Neuropathic Pain - Treatment With Pregabalin Under Real-life Conditions In Denmark

Observational study to assess the effectiveness and use of pregabalin (Lyrica) in the treatment of patients with peripheral neuropathic pain in real-life daily clinical practice.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

General practitioners and specialists participate in the study. When a subject, independently of the study and before consideration for observation in the study has been prescribed pregabalin for treatment of peripheral NeP, the subject can (before first dose of pregabalin is taken) be included in the observational program.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline In Average Pain Level At Month 3 Telephonic Interview
Time Frame: Baseline, Month 3 Telephonic Interview
Pain was assessed on an 11-point numeric rating scale (NRS) where a score of 0 indicated "no pain" and a score of 10 indicated "pain as bad as you can imagine".
Baseline, Month 3 Telephonic Interview
Change From Baseline In Worst Pain Level At Month 3 Telephonic Interview
Time Frame: Baseline, Month 3 Telephonic Interview
Pain was assessed on an 11-point NRS where a score of 0 indicated "no pain" and a score of 10 indicated "pain as bad as you can imagine".
Baseline, Month 3 Telephonic Interview
Change From Baseline In Least Pain Level At Month 3 Telephonic Interview
Time Frame: Baseline, Month 3 Telephonic Interview
Pain was assessed on an 11-point NRS where a score of 0 indicated "no pain" and a score of 10 indicated "pain as bad as you can imagine".
Baseline, Month 3 Telephonic Interview

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Sleep Interference Scale Score
Time Frame: Baseline, Month 1, 2, 3, Month 3 telephonic interview
Sleep Interference was assessed on an 11-point Sleep Numeric Rating Scale (NRS-11) where a score of 0 indicated "pain did not interfere with sleep" and a score of 10 indicated "pain completely interfered with sleep". Here, "n" signifies "Number of participants" for Baseline and Month 3 telephone interview whereas "n" signifies "number of observations" for Month 1, 2 and 3 because a participant could have had multiple visits during Month 1, 2 and 3 as this was a non-interventional study with no scheduled study visits, except Baseline visit and the Month 3 telephone interview.
Baseline, Month 1, 2, 3, Month 3 telephonic interview
Number of Participants With Categorical Scores On Patient Global Impression of Change (PGI-C)
Time Frame: Month 3 telephonic interview
PGIC: participant rated instrument to measure participant's change in overall status on a 7-point scale; range from 1 (very much improved) to 7 (very much worse). Number of participants in each category are reported.
Month 3 telephonic interview
Health-related Quality of Life Scale Score
Time Frame: Baseline, Month 1, 2, 3
Health-related Quality of Life was measured using Euro Quality of Life-5 dimensions (EQ-5D) scale. EQ-5D is a standardized generic instrument to assess health-related quality of life on 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression). The scale rates current participant's health state on a scale from 0 (worst imaginable health state) to 1 (best imaginable health state); higher scores indicate a better health state. Here, "n" signifies "Number of participants" for Baseline whereas "n" signifies "number of observations" for Month 1, 2 and 3 because a participant could have had multiple visits during Month 1, 2 and 3 as this was a non-interventional study with no scheduled study visits, except Baseline visit and the Month 3 telephone interview.
Baseline, Month 1, 2, 3
Work Productivity and Activity Impairment (WPAI) Questionnaire
Time Frame: Baseline, Month 1, 2, 3
WPAI questionnaire assess work productivity and impairment. It is a patient-rated, six-item questionnaire regarding current employment, hours missed and actually worked, and degree to which a specified health problem affected work productivity and regular activities over the past seven days. Subscale scores include Percent work time missed due to pain (PWP), Percent overall work impairment (PWI), Percent work productivity impairment due to pain (PWPI), Percent overall activity impairment (PAI). Each subscale score is expressed as an impairment percentage (0-100) where higher numbers indicate greater impairment and less productivity. Here, "n" signifies "Number of participants" for Baseline whereas "n" signifies "number of observations" for Month 1, 2 and 3 because a participant could have had multiple visits during Month 1, 2 and 3 as this was a non-interventional study with no scheduled study visits, except Baseline visit and the Month 3 telephone interview.
Baseline, Month 1, 2, 3
Pregabalin Dose
Time Frame: After Baseline Visit; Prior to Month 1, 2, 3, Month 3 Telephonic Interview; After Month 1, 2, 3, Month 3 Telephonic Interview
Here, "n" signifies "Number of participants" for Baseline and Month 3 telephone interview whereas "n" signifies "number of observations" for Month 1, 2 and 3 because a participant could have had multiple visits during Month 1, 2 and 3 as this was a non-interventional study with no scheduled study visits, except Baseline visit and the Month 3 telephone interview.
After Baseline Visit; Prior to Month 1, 2, 3, Month 3 Telephonic Interview; After Month 1, 2, 3, Month 3 Telephonic Interview
Number of Participants Using Other Pharmacological Pain Treatments For Peripheral Neuropathic Pain Before Baseline, Month 1, 2, 3 Visit
Time Frame: Before Baseline, Month 1, 2, 3 Visit
Pharmacological treatments included tricyclic antidepressants (TCA), gabapentin, non-steroidal anti-inflammatory drugs (NSAIDs), weak opioids, strong opioids, serotonin-norepinephrine reuptake inhibitors (SNRIs), lidocaine or capsaicin patch (L/C) and other (parcetamol containing drugs, xylocain gel or kinin). Participants may have used more than one pharmacological pain treatments and may be presented in more than 1 category.
Before Baseline, Month 1, 2, 3 Visit
Number of Participants Using Other Pharmacological Pain Treatments For Peripheral Neuropathic Pain After Baseline Visit (Concomitant Medication)
Time Frame: After Baseline, Month 1, 2, 3 visit
Pharmacological treatments included tricyclic antidepressants (TCA), gabapentin, non-steroidal anti-inflammatory drugs (NSAIDs), weak opioids, strong opioids, serotonin-norepinephrine reuptake inhibitors (SNRIs), lidocaine or capsaicin patch (L/C) and other (parcetamol containing drugs, xylocain gel or kinin).
