Creating Connections on Capitol Hill

On February 4, 2024 RLS Foundation Executive Director Karla Dzienkowski, board chair Dr. Shalini Paruthi and staff member Adrianna Colucci traveled from their southern states to Washington, DC. Spanning two days, they met with 10 legislative offices, educating representatives on RLS and its impact on the patient community. These meetings emphasized the need for increased research funding, enhanced education and awareness and protected access to critical therapies including low-total-daily dose opioids. This visit comes at a pivotal time when committees are making key decisions on policy issues within federal agencies.

The United States Senate Committee on Appropriations, in particular, was targeted. This committee has jurisdiction over all discretionary spending in the Senate. Their responsibility is to write legislation allocating funds to federal agencies and departments each year.¹ The RLS Foundation met with the offices of Senators Jon Tester (MT), Jack Reed (RI) and John Boozman (AR), all of whom serve on the Appropriations Committee. Philip Goglas, managing partner at the Health and Medicine Counsel (HMC) and Matt Duquette, coordinated the Capitol Hill meetings. Goglas states that “we meet with appropriators because they decide how much funding the National Institutes of Health (NIH) and Centers for Disease Control and Prevention (CDC) receive and further, what conditions are eligible for study.”

The Foundation asked that the NIH be provided with sustained funding for fiscal year (FY) 2024 of at least $50.924 billion. Researchers can apply for grants to conduct crucial RLS research through funding across relevant NIH centers.

The Foundation also requested at least $6 million in funding for the Chronic Diseases Education and Awareness Program (CDEA) at the CDC. The CDC has an active public health campaign dedicated to sleep disorders which will end in 2024.² Funding for the CDEA allows valuable public health efforts to increase education and awareness to continue.

Meetings with members of the Defense Committee and Subcommittees from both the Senate and House were also pursued, including the offices of Senators John Tester (MT), who is Chair of the Defense Subcommittee, Jack Reed (RI), and Congressman Steve Womack (AR). The Defense Committee oversees the nation’s military including the Department of Defense (DoD). The DoD Peer-Reviewed Medical Research Program (PRMRP) is a program designed to support research to enhance the health and well-being of military service members, veterans, retirees, and their family members. RLS is a major sleep disorder that affects an estimated 40,000 active-duty military personnel. Including “sleep disorders” in the PRMRP, allows researchers to apply for grants related to sleep medicine, including RLS. The RLS Foundation’s Scientific and Medical Advisory Board member, Dr. Brian Koo of Yale University, was awarded a research grant under the PRMRP.

The Foundation also met with members of the House Energy and Commerce and Ways and Means committees as well as the Labor Health and Human Services subcommittees which have oversight on policy affecting healthcare, specifically for opioid-related legislation. The Foundation asked for accommodations for patients who rely on the regular use of low-total-daily doses of opioids to manage their RLS. When legislation addressing the opioid epidemic is introduced, it is important to consider the needs of the RLS community by carving out the same accommodations for the use of opioids in other disorders such as sickle cell anemia, cancer and palliative care. The Foundation stressed the need for physicians to prescribe opioids appropriately and without arbitrary barriers.

Representing the RLS community as both a patient and sleep physician, Dr. Paruthi emphasized that the RLS community needs additional research to better understand the pathophysiology of RLS and to improve treatments. “We work with legislative staff to shed light on what RLS individuals suffer from and how it disrupts daily life,” she says.

Advocacy plays a pivotal role in shaping public policy, bridging the gap between the community and lawmakers. Thank you to Matt Duquette and Phil Goglas from the HMC for coordinating these meetings and leading our advocacy efforts.

Progress Report #12: National RLS Opioid Registry

Relevance:

This project continues to be relevant to the Restless Leg Syndrome Foundation’s mission to improve the quality of life for those living with RLS. The National RLS Opioid Registry is collecting much-needed data on the efficacy and safety of long-term opioid treatment for RLS. Opioids have been shown to successfully treat the symptoms in patients with severe RLS, even when current approved treatments lost effectiveness; however, there is a lack of concrete data to support opioids as a treatment option. Given the current overdose crisis, data on the efficacy and safety of opioids for the treatment of RLS is needed so that providers and patients can make informed treatment decisions, especially in the face of increasingly strict opioid regulations.

Research Goals and Methodology:

By asking questions about specific opioid dosages over time (including the first stable dose) and validated questions about RLS severity (IRLS, RLS-QLI), we aimed to assess the efficacy of opioid medications in the treatment of RLS. By asking questions about specific side effects over time, we aimed to assess the tolerability and safety of opioid medications. By obtaining a medical and psychiatric history, a list of concomitant medications, and information on habits, behaviors, and mood, we aimed to further understand how these factors may influence the efficacy and safety of opioid medications in this population.

We originally set a goal to enroll 200 subjects within 2 years. We surpassed that goal, having enrolled 502 subjects. Enrollment was closed in September 2019. Upon enrollment, participants completed a phone interview lasting approximately 45 minutes. Information about RLS symptoms, past and current medications, specific dosages, and opioid side effects was collected during this interview, in addition to more sensitive information related to psychiatric conditions and opioid risk factors.

After the phone interview, participants were sent an online survey that took approximately 15 minutes to complete and was completed within 7 days of the phone interview (extensions were given under certain circumstances). This online survey collected information on medical history, sleep behavior, habits, recreational drug use, and mood. A total of 500 of 502 enrolled subjects completed the baseline survey. Every 6 months following the initial enrollment interview, participants are sent a follow-up survey that takes approximately 20 minutes to complete. The follow-up survey consists of a combination of questions from the baseline phone interview and baseline online survey, and it should be completed within 7 days. The links to access both the baseline and follow-up online surveys are sent to personal email addresses.

Recruitment

We recruited participants from established RLSF Quality Care Centers around the country, and via RLSF circulated media. Designated and interested clinicians were provided with study brochures to give to potentially eligible patients. The brochure contained the necessary contact information to enroll in the Registry, and this contact information was also provided on the RLSF website and newsletter.

Enrollment

Enrollment was limited to individuals with: a diagnosis of RLS, confirmed by the Hening-Hopkins Telephone Interview at the start of the baseline phone interview; an opioid prescription, which may be confirmed by state prescription drug monitoring programs; and a past medication history that includes a positive response to dopamine agonists for RLS treatment, as confirmed by a question about past RLS treatments.

Longitudinal follow-up

We continue to send 6-month follow-up surveys to all remaining participants (excluding those who have discontinued opioids and those who are deceased). A total of 467 participants completed the 1-year follow-up survey (97.7% retention), 458 completed the 2-year follow-up survey (95.2% retention of eligible participants), 441 completed the 3-year follow-up survey (94.1% retention), 425 completed the 4-year follow-up survey (93.6% retention), and 288 completed the 5-year follow-up survey.

At this time (December 2023), 23 subjects are considered lost to follow-up, 9 subjects withdrew, 18 subjects are deceased, and 38 subjects discontinued their opioid treatment (see Figure 1). Retention is high as a result of participant commitment and our continuing efforts to encourage participation through vigilant follow-up with participants (emails, phone calls) as well as emailing quarterly analyses data updates.

Data analyses

As of this date, we have assessed baseline, 1-year, 2-year, 3-year, and 4-year longitudinal data from the RLS Registry. These analyses revealed that in refractory RLS, prescribed opioids are generally used at low doses with good efficacy. Longitudinally over 4 years, roughly one-half of participants increased their prescribed opioid dose, though generally by small amounts, with larger dose increases accounted for by predictable features. Our 1-year data has been published in Sleep. We have also analyzed data relating to the effects of COVID on the severity of RLS symptoms just prior to, and following, the national lockdown in March 2020. Our 2-year data was presented at the annual APSS meeting (June 2021) and published in Neurology. A poster on suicidality in the Registry using the 2-year data was presented at APSS Sleep 2023 in Indianapolis, and we are in the process of publishing a manuscript on the same subject. Findings from the 3-year data were presented at World Sleep 2023 in Rio de Janeiro, and we intend to present our 4-year findings at APSS Sleep 2024 in Houston, Texas.

Ten data updates using Registry data have been sent to participants. These include data summaries such as RLS and mental health, RLS severity during the COVID-19 pandemic, the stigma of opioid treatment for RLS, suicidality in the RLS Registry, and much more. All of the quarterly updates can be accessed on the RLS Registry webpage. We plan to continue sending updates to participants on a quarterly basis.

The Registry remains open to collaborators who desire to examine specific questions relating to RLS which can be addressed through its database. One such collaborator, Dr. Elias Karroum, has been assessing the effects of painful RLS on outcomes collected through the Registry and he has submitted an abstract describing his findings to APSS Sleep 2024 in Houston, Texas.

Conclusion

At this time, we are very pleased that the Registry is obtaining the data we had hoped, and participant commitment is high, as demonstrated by low rates of attrition. We aim to accurately answer questions about the efficacy and safety of opioid medications for the treatment of RLS, and in doing so, we are keeping with the RLSF’s mission to improve the lives of those living with RLS.

RLS Foundation and American Academy of Sleep Medicine Foundation Announce Research Grant Opportunity

The Restless Legs Syndrome (RLS) Foundation and the American Academy of Sleep Medicine Foundation (AASM Foundation) today announced a new collaboration to co-fund a $50,000 grant for research on restless legs syndrome (RLS). The funding will be made available through the RLS Foundation’s Research Grant Program, which has awarded over $1.9 million in grants for medical research on RLS causes and treatments since 1997.

“The RLS Foundation’s partnership with the American Academy of Sleep Medicine Foundation signifies our shared commitment to expanding the availability of RLS research funding,” says RLS Foundation Executive Director Karla Dzienkowski.

RLS is a chronic neurological disease characterized by an irresistible urge to move the legs, especially at night. Many people with RLS endure unrelenting symptoms that severely disrupt sleep and can have a devastating impact on their well-being. “For people who live with the daily challenges of RLS, research offers hope for new, durable treatments leading to better treatment outcomes and improved quality of life,” says Dzienkowski. An estimated 7%–8% of adults in the US have RLS, and treatments are limited.

“The AASM Foundation is excited to collaborate with the RLS Foundation on funding a research grant opportunity that will contribute to our understanding of RLS and help optimize treatment options and care delivery for people with RLS,” says R. Nisha Aurora, MD, MHS, President of the AASM Foundation.
