Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 89 years
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Age between 18 and 89.
- Treatment naïve patients (who are not taking RLS medications for at least 1 year) without coexisting untreated OSA.
- Diagnosed with RLS based on ICSD -3 criteria
- INI OSF Sleep medicine outpatient clinic patients.
- Patients with the ability to provide informed consent.
Who cannot join
- Patients who are currently taking magnesium supplements or took magnesium supplements in the last 3 months.
- Patients not on a stable dosage of medications ( patients requiring dosage changes) that can cause PLMs or worsen RLS will be excluded ( medications include antidepressants such as SSRIs, SNRIs and TCAs and Antihistamines such as Benadryl and Allegra, etc)
- Patients with a history of chronic kidney disease or end-stage renal disease on Hemodialysis
- Patients with known allergies to magnesium citrate
- Patients with congestive heart failure with an ejection fraction less than 40%, bradycardia with a resting heart rate below 60 and systolic blood pressure less than 90 mm of Hg.
- Patients with diarrhea
- Patients on gabapentin or pregabalin for pain syndromes
- Pregnancy. (Absence of pregnancy will be determined via subject self-reporting only. Subject self-reporting of the absence of pregnancy is sufficient screening because the dosage of Magnesium supplement that subjects will be consuming during the study is well below the NIH Tolerable Upper Intake Levels for pregnancy [see "Dietary Recommendations" below], and has been shown to cause no fetal abnormalities or pregnancy complications at the dosage patients will consume for the study. Subjects will be encouraged to practice appropriate measures to avoid pregnancy throughout the entirety of their study participation).

About this study
Official title: The Effect of Magnesium Citrate Supplementation in Patients With Restless Legs Syndrome (RLS) - An Open Label, Prospective, Non Placebo Controlled Pilot Study
The expected results of this study will have a significant impact on the treatment of RLS/WED patients. Magnesium supplementation (if proven to be beneficial) can be utilized as an inexpensive, safer, biologically plausible alternative to dopamine agonists and α2δ calcium-channel ligands.
Read the detailed description
This is an open-label, prospective, non-placebo controlled pilot study. 15 subjects with a diagnosis of restless legs syndrome (ICSD-3 diagnostic criteria) will be recruited from OSF Healthcare Saint Francis Medical Center sleep center and Illinois Neurological Institute. RLS/WED patients who meet inclusion and exclusion criteria during the initial clinic visit will be offered study participation. Standard treatment options will be discussed prior to the enrollment. Patients will be reassured that not participating in the study will not affect the future care they receive at OSF HealthCare. The potential risks and benefits of the study will be provided and, if the patient is interested, informed consent will be obtained. If the subject withdraws consent or does not finish both pre and post evaluation, we will replace the subject with another new recruit. The subject will come to the clinic for 2 visits, a pre-magnesium visit and a post-magnesium visit. Following the completion of the pre-magnesium visit, the subject will be given 200 mg elemental magnesium daily (will be instructed to take with food at dinner) for 8 weeks. Both Visits the following study procedures will be performed: magnesium level, (International Restless Legs Syndrome) IRLS scale, Kohnen Restless Legs Syndrome Quality of Life Instrument (KRLS-QOL) scale and (Multiple Suggested Immobilization (MSI) test. The post magnesium visit will be schedule at the completion of the 8 week dose of magnesium.

What is being measured
The primary outcome is the main question the study is designed to answer.
Subjective Improvement of Restless Legs Symptoms measured by the International Restless Legs Syndrome Scale (IRLS)
International Restless Leg Syndrome Scale. (IRLS) is a 10 question scale that subjects rate on a scale of 0-4; RLS can be classified as mild, moderate, severe and very severe, if the score is 0-10 (mild), 11-20 (moderate), 21-30 (severe) or 31-40 (very severe) respectively. The lower score reflects less symptom burden. Minimum score is 0 with a Maximum of 40.
Measured: Completion of Study participation at 8 weeks
Subjective Improvement of Restless Legs Symptoms measured by the Kohnen Kohnen Restless Legs Syndrome Quality of Life Instrument (KRLS QOL)
Kohnen Restless Legs Syndrome Quality of Life instrument (KRLS QOL) is a self-administered validated patient-reported outcome measure with 12 questions that assess the quality of life in RLS patients. Scores range from 0-60.The lower score represents less impact of RLS symptoms on quality of life.
Measured: Completion of Study participation at 8 weeks
Objective Improvement of Restless Legs Symptoms: Multiple Suggested Immobilization test (MSI) Score
Reduction in Multiple Suggested Immobilization test (MSI) discomfort Scores, range: 0-10, with a maximum total sum of 60 per hour. Three 1 hour trials will be conducted. Periodic limb movements during wakefulness will also be measured. Periodic limb movement index (PMLI) reflects periodic limb movements per hour. PMLI value of 0 indicates absence of limb movements and higher scores are often seen in patients with severe RLS
Measured: Completion of Study participation at 8 weeks
Correlation of magnesium levels with Kohnen Restless Legs Syndrome Quality of Life Instrument (KRLS) and Multiple Suggested Immobilization test (MSI) scores
Assessment of Magnesium level, lab value will be assess. Normal values range from 1.6 - 2.6 mg/dl. The rationale of measuring serum magnesium level is to analyze whether serum magnesium levels correlate with other subjective and objective RLS outcome measures
Measured: Completion of Study participation at 8 weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The expected results of this study will have a significant impact on the treatment of RLS/WED patients. Magnesium supplementation (if proven to be beneficial) can be utilized as an inexpensive, safer, biologically plausible alternative to dopamine agonists and α2δ calcium-channel ligands.

Questions about this trial
What is this clinical trial studying?
A study testing Magnesium Citrate in people with Restless Legs Syndrome, run by OSF Healthcare System at 1 site in United States.
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 5 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 17 Feb 2023. 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 United States. 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. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ashwath R Ravisankar, MBBS ((309) 624-5422, ashwath.r.ravisankar@osfhealthcare.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Subjective Improvement of Restless Legs Symptoms measured by the International Restless Legs Syndrome Scale (IRLS) (time frame: Completion of Study participation at 8 weeks). The study lists 4 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 NCT04462796, which also lists 24 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 17 Feb 2023.
