Repetitive Transcranial Magnetic Stimulation as Therapy for Depression in Amyotrophic Lateral Sclerosis
A study testing active repetitive transcranial magnetic stimulation in people with Amyotrophic Lateral Sclerosis, run by Jagiellonian University at 1 site in Poland.
Trial summary
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive loss of central and peripheral motor neurons. ALS leads to death usually within 3 to 5 years from the onset of the symptoms. Available treatment can prolong the disease duration but cannot modify the disease course. Read more about this study

About this study
Official title: A Pilot Study of Repetitive Transcranial Magnetic Stimulation for Improvement of Depression in Amyotrophic Lateral Sclerosis
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive loss of central and peripheral motor neurons. ALS leads to death usually within 3 to 5 years from the onset of the symptoms. Available treatment can prolong the disease duration but cannot modify the disease course. Depression is a frequent complication of ALS, which further decreases quality of life and the available data concerning effectivity of antidepressant drugs are conflicting. Repetitive Transcranial Magnetic Stimulation (rTMS) is a noninvasive method of modulation of brain plasticity with confirmed antidepressive effect. The purpose of this study is to compare the effectiveness of rTMS in improving the depression in patients with ALS with placebo stimulation. Intervention will include 10 daily sessions. In each session 3000 magnetic pulses will be administered over the left dorsolateral prefrontal cortex. Assessment depression severity will be made before and after therapy, as well as two and four weeks later.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive loss of central and peripheral motor neurons. ALS leads to death usually within 3 to 5 years from the onset of the symptoms. Available treatment can prolong the disease duration but cannot modify the disease course. Depression is a frequent complication of ALS, which further decreases quality of life and the available data concerning effectivity of antidepressant drugs are conflicting. Similarly, the apathy may also complicate ALS and worsen the prognosis. Repetitive Transcranial Magnetic Stimulation (rTMS) is a noninvasive method of modulation of brain plasticity with proved antidepressive effect in patients suffering from major depression and in depression associated with several neurological disorders such as Parkinson's disease or stroke.
The purpose of this study is to compare the effectiveness rTMS in improving the depression and - as a secondary outcome - the apathy and daily functioning in patients with ALS.
Intervention will include ten daily sessions of rTMS. In each session 3000 magnetic pulses will be administered over the left dorsolateral prefrontal cortex. Stimulation intensity will equal 120% of the motor threshold value for the right first dorsal interosseus.
Assessment of depression severity and of apathy and daily functioning will be made before and after therapy, as well as two and four weeks later.

ALS leads to death usually within 3 to 5 years from the onset of the symptoms. Available treatment can prolong the disease duration but cannot modify the disease course. Depression is a frequent complication of ALS, which further decreases quality of life and the available data concerning effectivity of antidepressant drugs are conflicting. Repetitive Transcranial Magnetic Stimulation (rTMS) is a noninvasive method of modulation of brain plasticity with confirmed antidepressive effect. The purpose of this study is to compare the effectiveness of rTMS in improving the depression in patients with ALS with placebo stimulation. Intervention will include 10 daily sessions.

Questions about this trial
What is this clinical trial studying?
A study testing active repetitive transcranial magnetic stimulation in people with Amyotrophic Lateral Sclerosis, run by Jagiellonian University at 1 site in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 10 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Beck's Depression Inventory ater rTMS, total score, range 0 to 63, with higher values representing a worse outcome (time frame: Before rTMS, directly (on the same day) after finishing rTMS). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03892863, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Feb 2020.
