Study of Mirogabalin for Central Neuropathic Pain

An Asian, Multicenter, Randomized, Double-blind, Placebo-controlled, 14-week Study of Mirogabalin in Participants With Central Neuropathic Pain Followed by a 52-week, Open-label Extension

Investigate the efficacy and safety of mirogabalin in participants with central neuropathic pain in comparison to placebo

Study Overview

• Status: Completed
• Conditions: Central Neuropathic Pain
• Intervention / Treatment: Drug: Placebo; Drug: Mirogabalin

Detailed Description

[Double Blind Phase] The primary objective is to compare change in the Average Daily Pain Score (ADPS) from baseline to Week 14 in Asian participants with central neuropathic pain (central neuropathic pain after spinal cord injury) receiving mirogabalin versus placebo.

[Open Extension Phase] The objective is to assess the long-term safety and efficacy of mirogabalin in participants with central neuropathic pain (central neuropathic pain after spinal cord injury, central post stroke pain, and central neuropathic pain in Parkinson's disease).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Average Daily Pain Score (ADPS)	The pain scores on a scale of 0-10, where 0 = no pain and 10 = the worst possible pain. The weekly ADPS is based on participants daily pain scores.	Baseline to Week 14

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Average Daily Pain Score (ADPS) Response Rate	Ratio of Participants Responding to Treatment, as Measured by Average Daily Pain Score (ADPS) Reduction from Baseline. The ADPS is used to determine categorical response rates.	at Week 14
Pain Intensity Score Using the Short-Form McGill Pain Questionnaire (SF-MPQ)	Participants rate their pain in three parts of the questionnaire, which are combined into a single pain intensity score: Part 1 - fifteen descriptors of pain intensity, on a scale of 0 (none) to 3 (severe) Part 2 - a VAS, in which the participant rates pain on a 100 mm-long horizontal line, where 0 mm = no pain and 100 mm = worst possible pain Part 3 - a Present Pain Intensity index in which the participant rates present pain intensity on a scale of 0 (no pain) to 5 (most intense pain)	Baseline to Week 14
Patient Global Impression of Change	Participants rate their overall impression of how the present pain compares to baseline using a 7-point scale, where 1 = very much improved and 7 = very much worse. Patient Global Impression of Change scores are used to determine categorical responder rates.	at Week 14
Average Daily Sleep Interference score (ADSIS)	The sleep interference scores on a scale of 0-10, where 0 = pain did not interfere with sleep to 10 = pain completely interfered with sleep. The weekly ADSIS is based on participants daily sleep interference scores.	Baseline to Week 14
