Filter by:The purpose of this study is to see if therapy with the drug pregabalin relieves pain during shingles compared with placebo. A placebo is an inactive substance. Pregabalin is a drug marketed as Lyrica™ in the United States for the treatment of seizures, diabetic neuropathy, and post-herpetic neuralgia. The use of pregabalin and drugs like it for the treatment of pain during the acute phase of shingles is experimental. Thirty four subjects will complete the study at the University of California, San Francisco (UCSF) Pain Clinical Research Center. This study is funded by Pfizer Global Research.
This trial was the follow-on trial to a preceeding double-blind, placebo controlled trial which included patients with at least moderate pain due to postherpetic neuralgia. It was conducted at six sites in Germany and has been clinically finalized. The patients had successfully completed the above mentioned trial in postherpetic neuralgia and, in the investigator's opinion, would benefit from long-term administration of Lacosamide. After a 1-week run-in phase the patients were uptitrated to their optimal dose and then continued into the maintenance phase. Dose adjustments were allowed throughout the trial.The change in pain was measured daily as well as interference of pain with sleep and general activity. As per protocol this trial was terminated after two years of treatment.
4-month study including a 30-day baseline phase
The incidence and severity of HZ (or shingles), as well as the frequency and severity of its complications, increases markedly with increasing age. More than half of all cases occur in persons over the age of 60. Even without complications, HZ can interfere with an elderly patient's ability to perform essential activities of daily living, resulting in a loss of independence that is emotionally devastating and frequently irreversible. The most common complication of HZ in elderly persons is postherpetic neuralgia (PHN), which frequently results in disordered sleep, chronic fatigue, anxiety and severe depression. Antiviral therapy has a modest impact on the acute phase of HZ. However, it does not appear to prevent the development of PHN. This study is a 5.5 year randomized, double-blind, placebo-controlled, efficacy trial to determine whether vaccination with live-attenuated Oka/Merck varicella-zoster decreases the incidence and/or severity of herpes zoster (HZ) and its complications in adults 60 years of age and older.
