NCT01750346
Background: \- Blepharospasm is caused by excessive contraction of the muscles that close the eye. One treatment is botulinum neurotoxin (BoNT), which works by weakening those muscles. Like BoNT, acetyl hexapeptide-8 (AH-8) works to weaken the muscles, but is available as a skin cream. AH-8 is the active ingredient in a number of cosmetic creams used to treat wrinkles. Researchers thought that AH-8 cream could be used to treat blepharospasm, but the original dose studied was not very effective. They want to try a higher dose of AH-8 in a cream to see if it can be a more effective treatment. Objectives: \- To see if AH-8 cream can improve the symptoms of blepharospasm. Eligibility: \- Individuals at least 18 years of age who have blepharospasm that is severe enough to require treatment. Design: * This study will involve up to eight study visits. * Participants will be screened with a physical exam and medical history. They will answer questions about their symptoms. They will also have a blink test to see how severe the blepharospasm is. At this visit, participants will receive one of three types of cream. One cream will have a low dose of AH-8, one will have a higher dose of AH-8, and the other will be a placebo (no AH-8). * One month later, participants will have a followup visit, with tests similar to the first visit. They will also receive more of the cream. * One month later, participants will have another visit with the same tests. They will be videotaped at this visit to study their facial movements. Those who have responded to the treatment will continue to use the cream. Those who have not responded will be offered the chance to have BoNT injections, and will stop taking the cream. * One month later, participants who had BoNT injections will have a final visit to check for possible side effects. Those who continued to take the cream will continue on the study. * The fifth and sixth visits will involve the same tests as before. At the seventh visit, remaining participants will be offered the chance to have BoNT injections, and will stop taking the cream. * The final visit will check for any side effects from the cream or the injections.
NCT01187511
Objective: To evaluate GSK561679, an orally available, brain penetrant selective CRH1 antagonist for its ability to reduce alcohol craving in recently detoxified alcohol dependent women in response to stress or alcohol-associated stimuli. Study population: Up to 60 anxious, alcohol dependent women, aged 21-65 years will be enrolled to complete the study in 50 patients. Background: * Anxiety, irritability, anger, and depression can all cause stress that may lead to continued drinking in heavy drinkers. One way the brain responds to stress is through a protein on brain cells called a CRH receptor. Previous research has shown that the CRH receptor is involved in negative emotional states and that chronic alcohol consumption increases the activity of CRH receptors in the brain. Medications that block CRH receptors can decrease stress-triggered alcohol consumption. * GSK561679, an experimental drug that blocks the CRH receptors, can reduce negative emotions such as anxiety and a person s desire for alcohol. By looking at the brain s response to stress and the study drug using functional magnetic resonance imaging (fMRI) scans, researchers hope to learn whether GSK561679 can be an effective treatment for stress-related alcohol abuse. Objectives: \- To evaluate the usefulness of GSK561679 in reducing stress-related alcohol craving in alcohol-dependent women. Design: * Participants in the study will be enrolled in the standard NIH treatment program for alcohol dependence, and will be required to stay at the NIH inpatient treatment unit for an additional 31 days. * Participants will receive either the study medication or a placebo to be taken once a day in the evening for 4 weeks. * Participants will have the following procedures while on the study medication: * Questionnaires about alcohol craving, depression, and anxiety. * Recordings and responses to personal emotional reactions to stressful, nonstressful, and alcohol-related situations, with blood samples taken during the responses. * Regular blood tests to measure stress hormones in the blood. * Speech preparation and presentation (Trier test), along with blood samples, to measure stress hormones in the blood. * Sessions to measure responses to alcohol-related cues. * Functional magnetic resonance imaging (fMRI) scans. * Participants will return for follow-up visits 1 week and 1 month after stopping the study drug and being discharged from the study.
