Extension Study to Evaluate the Long-Term Safety, Tolerability, and Maintenance of Effect of BIIB074
- Conditions
- Neuropathic Pain From Lumbosacral Radiculopathy
- Interventions
- Registration Number
- NCT02957617
- Lead Sponsor
- Biogen
- Brief Summary
The primary objective of the study is to evaluate the long-term safety and tolerability of BIIB074 in participants with neuropathic Pain From Lumbosacral Radiculopathy (PLSR). A secondary objective is to investigate the maintenance of effect during long-term treatment with BIIB074 in participants with neuropathic PLSR. For all efficacy assessments, baseline will be prior to randomization into Study 1014802-203. Another secondary objective is to evaluate the impact of treatment with BIIB074 on quality of life (QoL).

Group Intervention Description BIIB074 BIIB074 BIIB074 orally twice daily
- Primary Outcome Measures
Name Time Method Number of Participants experiencing Adverse Events(AE) and Serious Adverse Events (SAEs) Up to 395 Days Safety surveillance
- Secondary Outcome Measures
Name Time Method Change from Baseline at each visit in the weekly average of the daily neuropathic pain score Baseline through Week 52 Participants will be asked every evening to rate their overall neuropathic pain for the last 24-hour period.
Change from Baseline to Week 52 in the weekly average of the daily neuropathic pain score on the Pain Intensity Numerical Rating Scale (PI-NRS) Baseline to Week 52 Participants will be asked every evening to rate their overall neuropathic pain for the last 24-hour period. PI-NRS is an 11-point pain intensity numerical rating scale (PI-NRS), where 0=no pain and 10=worst possible pain.
Change from Baseline to Week 52 in the weekly average of the daily sleep score as assessed by the Sleep Numerical Rating Scale (S-NRS) Baseline to Week 52 Participants will be asked every morning to rate on the 11-point S-NRS how leg pain interfered with their sleep quality where 0=no pain and 10=worst possible pain.
Change from Baseline to Week 52 on the EuroQoL 5-Dimension 5-Level Questionnaire (EQ-5D-5L) health index Baseline to Week 52 The EQ-5D-5L is a standardized instrument for use as a measure of health outcome. It is a health questionnaire that consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ-5D-3L descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, extreme problems.
50% neuropathic pain reduction response At Week 52 Response is defined as a ≥50% reduction in the weekly average of the daily neuropathic pain score from Baseline to Week 52.
Change from Baseline to Week 52 in the weekly average of the daily pain score for low back pain Baseline to Week 52 Participants will be asked every evening to rate their overall low back pain for the last 24-hour period.
Number of Patient Global Impression of Change (PGIC) responder At Week 52 PGIC is a 7-point self-report scale depicting a participant's rating of overall improvement. Participants rate their change as "very much improved," "much improved," "minimally improved," "no change," "minimally worse," "much worse," or "very much worse."
Change from Baseline to Week 52 on the Oswestry Disability Index (ODI) Baseline to Week 52 This is a 10-item questionnaire that evaluates how back (or leg) pain affects the ability to manage in everyday life. Each question is rated on a 5 point scale with higher scores indicating higher level of pain.
Change from Baseline to Week 52 in the Brief Pain Inventory (BPI)-Interference Index Baseline to Week 52 BPI Interference Index is an 11-point numeric rating scale (0 - no interference to 10 - interferes completely) to assess pain-related interference in 7 areas: general activity, mood, walking ability, normal work, including outside the home and housework, relations with other people, enjoyment of life and sleep.
Change from Baseline to Week 52 in Short Form 36 Questionnaire (SF-36) Baseline to Week 52 SF-36 is a self-administered, generic health status questionnaire consisting of 36 questions that measure 8 health concepts: physical functioning, role limitations due to physical problems, bodily pain, general health perception, vitality, social functioning, role limitations due to emotional problems and mental health.
30% neuropathic pain reduction response At Week 52 Response is defined as a ≥30% reduction in the weekly average of the daily neuropathic pain score from Baseline to week 52.
Change from Baseline to Week 52 in the BPI - Pain Index Baseline to Week 52 BPI- Pain Index for pain intensity, is used to assess potential pain quality descriptors that may describe participants' pain on a scale of 0 (no pain) to 10 (pain as bad as you can imagine).
