Device for Treating Generalized Anxiety
Evaluation of the Efficacy and Safety of an Accelerated Protocol for Treating Generalized Anxiety Disorder Using the BTL-699-2 Device
The goal of this clinical trial is to learn if treatment with the BTL-699-2 device (non-invasive repetitive transcranial magnetic stimulation) can decrease anxiety symptoms in adults (aged 22 years and older) diagnosed with Generalized Anxiety Disorder (GAD). The main questions it aims to answer are:
Does the accelerated treatment protocol using the BTL-699-2 device reduce self-reported anxiety symptoms (as measured by the GAD-7 scale) 3 months after the final treatment? What are the safety and side effects associated with the use of the BTL-699-2 device during this accelerated protocol? Researchers will compare the active treatment group (Group A, receiving stimulation intensity of up to 70% of the individual's motor threshold) to a sham control group (Group B, receiving an inactive stimulation intensity of 5% of their motor threshold) to see if the active brain stimulation works to treat Generalized Anxiety Disorder.
Participants will:
- Attend a screening/baseline visit to confirm GAD diagnosis (using the MINI diagnostic interview), review medical history, and establish their individual motor threshold.
- Complete 8 study treatment visits scheduled twice weekly (2 to 4 days apart) over approximately 4 weeks. Each visit will consist of two consecutive 19-minute treatment sessions delivered at least 15 minutes apart (for a total of 16 treatments).
- Complete self-reported and clinician-reported questionnaires assessing anxiety (GAD-7, HAM-A), depressive symptoms (PHQ-9), well-being (WEMWBS), suicidal risk (CSSRS), clinical improvement (CGI-I, PGI-I), and treatment comfort/satisfaction (TCQ, SSQ) at designated baseline, treatment, and follow-up visits.
- Undergo a urine pregnancy test at baseline and once weekly (every other treatment visit) if they are women of childbearing potential.
- Attend 2 follow-up visits scheduled at 1 month and 3 months after the final treatment to evaluate long-term outcomes and safety

Any other disease or condition at the investigator's discretion that may pose risk to the patient or compromise the study
Examples include cochlear implants, implanted electrodes/stimulators, aneurysm clips or coils, stents, bullet fragments, jewelry and hair barrettes. Failure to follow this restriction could result in serious injury or death. Certain exceptions apply to mouth implants, such as standard amalgam dental fillings, single post dental implants, dental bridge work, and braces. If these items are present, the therapy can still be administered.
By means of decompensation, it means a patient with a proven medical history of a decompensated health condition and long-term medication. Patients who use certain medications only for preventive purposes, without any proven previous health condition failure, are not considered contraindicated.
- Defined by a score of Level 4 or Level 5 on the Columbia-Suicide Severity Rating Scale (CSSRS).

Evaluation of Therapy Comfort
Časové okno: Last Treatment
|
Therapy Comfort questionnaire consists of two questions and will be used for evaluating the comfort and pain during the treatment sessions.
The Therapy Comfort questionnaire will be administered after the last treatment.
The first question "I found the treatment comfortable", to which responses are based on a 5-point Likert scale (1 = "strongly disagree", and 5 = "strongly agree").
A higher score for the statement "I found the treatment comfortable" indicates higher therapy comfort.
The second question includes a 10-point Numeric Analog Scale for pain (0 = no pain, 10 = worst possible pain).
Lower scores on the Numeric Analog Scale indicate lower levels of pain.
