Descriptive Information
Brief Title  ICMJE Pilot Study Of Pregabalin And Prediction Of Treatment Response In Patients With Postherpetic Neuralgia
Official Title  ICMJE A Phase 4 Multicenter, Open-Label, Pilot Study Of Pregabalin And Prediction Of Treatment Response In Patients With Postherpetic Neuralgia
Brief Summary The primary objective is to explore whether sensory symptom cluster analysis is useful for predicting treatment response in Postherpetic Neuralgia.
Detailed Description The study was stopped on 26 April 2013 due to feasibility issues (low enrollment) not safety. The overall risk-benefit of Lyrica has not changed at all due to termination of this trial. Only 9 of the 150 patients were enrolled into the trial, so we are unable to get adequate results from this study.
