Brain GABA-B Function clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

GABA-B Receptor Function in Healthy Volunteers

Start date: July 2013
Phase: N/A
Study type: Interventional

There are several developing lines of evidence suggesting that brain receptors called GABA-B receptors play a significant role in addiction and its treatment. The investigators wish to examine the sensitivity of brain GABA-B receptors in alcohol and opiate addicts as part of the investigators MRC programme of research in neurotransmitters in alcohol and opiate addiction (NOAA). In this present study the investigators will give 2 different single doses of a drug called baclofen, and a placebo, to 8 healthy male volunteers. This drug affects GABA-B receptors in the central nervous system and is licensed for the treatment of spasticity in people with eg spinal injuries; the investigators are interested in its effects on brain GABA-B receptors. The investigators will measure EEG (brainwaves), eye movements, blood pressure and heart rate, motor co-ordination and subjective effects and also blood levels of the drug in the investigators volunteers before and at intervals after dosing. The investigators will use a double-blind randomised design to minimise expectation effects. The study will provide information on timing and magnitude of effects of baclofen on brain function in healthy subjects so that the investigators can optimise selection and timing of functional measures in future studies of addicts.
