Priming in Repetitive Transcranial Magnetic Stimulation in the Treatment

Status Recruiting

Clinical Trial Summary

Obsessive Compulsive Disorder results in high social impact, affecting quality of life and tending to a chronic course. A considerable proportion of patients, up tp 60%, remain with symptoms even thought treatment is administrated. Therefore, new therapeutic interventions are highly necessary. In this context, repetitive transcranial magnetic stimulation has been used for several psychiatric conditions, including OCD treatment. Moreover, many approaches of neuromodulation seem to reach a better result when used a priming stimulation. In an attemp to optimize particularities of the thecnique applied, this study aims to assess if a priming stimulation with rTMS might impact in a better outcome when compared with rTMS without previous stimulation.

Clinical Trial Description

This is a randomized, double-blind, sham-controlled clinical trial. Neuropsychological tests and a sociodemographic and clinical questionnaire will be used to assess and characterize the subjects. Participants captured by the Laboratory of Studies in Aging and Neuroscience at the Federal University of Paraíba will be divided into 02 groups, each with 16 patients, totaling 50 volunteers: Active - participants who will receive real priming stimulation; Sham - participants who will receive simulated priming stimulation. Participants entered through the eligibility criteria will be randomly allocated in a simple way, at a rate of 1:1. In the active priming, the parameters are: frequency of 6 Hz for 10 minutos, 80% do Motor Threshold (MT), 20 trains of 5 seconds, with intertrain interval of 25 seconds, a total f 600 stimulations. The group of innactive priming will have the same parameters, but without active atimulation. After this previous stimulation, all participants will receive the main stimulation: 10 sessions of rTMS, each lasting around 20 minutes, for 5 days a week, during two consecutive weeks. The target area will be the supplementary motor area. Primary outcome will be assessed by change in Yale-Brown Obsessive Compulsive Scale scores. As secondary outcomes, it will be used HAM-A for anxiety, HAM-D for depression, CGI-S for global clinical impression and SF-36 for quality of life. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

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.
