Summary

The purpose of this study is to evaluate if pregabalin relieves nerve pain associated with spinal cord injury compared to placebo (pill that contains no active medicine). This study will also evaluate the safety of pregabalin in this patient population.

Clinical Details

Official title: A 17-Week, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multi-Center Trial Of Pregabalin For The Treatment Of Chronic Central Neuropathic Pain After Spinal Cord Injury

Study design: Treatment, Randomized, Double Blind (Subject, Investigator), Parallel Assignment, Safety/Efficacy Study

Primary outcome: The mean of all post-baseline scores derived from subject's daily pain diary, where pain is measured on an 11-point Numerical Rating Scale (NRS-Pain), observed up to a 17-week period.

Secondary outcome:

Weekly mean pain score changes from baseline up to 16 weeks

30% and 50% responder rates in reduction of pain from baseline up to 16 weeks

The Patient Global Impression of Change score measured at treatment termination after a treatment period of up to 16 weeks

Weekly mean sleep interference score changes from baseline up to 16 weeks

The modified Brief Pain Inventory Interference Scale score changes from baseline up to 17 weeks

The Quantitative Assessment of Neuropathic Pain score changes from baseline up to 1 7 weeks

Endpoint mean sleep interference score

Neuropathic Pain Symptom Inventory

The Hospital Anxiety and Depression Scale score changes from baseline up to 17 weeks

The Medical Outcomes Study Sleep Scale score changes from baseline up to 16 weeks

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- At least 4 completed pain diaries with an average daily pain score of at least 4

during the 7 days prior to randomization.

- The pain is a chronic unilateral or bilateral, central, below level of neurological

injury neuropathic pain, i. e., pain persisted continuously for at least 3 months or with remissions and relapses for at least 6 months and to have started after spinal cord injury; the central nervous system.

Exclusion Criteria:

- Creatinine clearance <60 mL/min.

- White blood cell count <2500/mm3; neutrophil count <1500/mm3; platelet count <100 x

103/ mm3.

- Abuse of drugs or alcohol

- Unstable medial conditions

- Clinically significant abnormal electrocardiogram (ECG).

- Presence of severe pain associated with conditions other than spinal cord injury that

could confound the assessment or self-evaluation of pain due to spinal cord injury.
