Final critical papers on RECOVER clinical study data accepted, supporting the Company’s submission for coverage reconsideration 

Strong 24-month top-line data for RECOVER clinical study demonstrates durability of VNS Therapy

In-depth analysis on suicidality at 12 months yields positive results 

LONDON--(BUSINESS WIRE)--Jun. 4, 2025-- LivaNova PLC (Nasdaq: LIVN), a market-leading medical technology company, today announced it has initiated the process with the U.S. Centers for Medicare and Medicaid Services (CMS) to seek reconsideration of national Medicare coverage for VNS Therapy™ in unipolar patients with treatment-resistant depression (TRD). The first step in the process for making a National Coverage Determination (NCD) is the submission of a draft formal request for CMS reconsideration.

Five critical articles featuring outcomes from in-depth data analyses on primary and select secondary endpoints in the RECOVER study have recently been published in or accepted by peer-reviewed journals, and the totality of data presented in these articles serves as the basis of the Company’s request to CMS. The company believes these articles satisfy the Coverage with Evidence Development (CED) requirement of sharing peer-reviewed, publicly accessible results of pre-specified outcomes measured in the RECOVER study. In addition to the five articles, the request for coverage reconsideration includes strong 24-month clinical outcomes from the unipolar cohort of the RECOVER clinical study that demonstrate the substantial retention of benefits and the durability of VNS Therapy over time.

“We have reached an important point in our pursuit to obtain national coverage for VNS Therapy for unipolar patients with depression that is difficult to treat,” said Ahmet Tezel, Ph.D., Chief Innovation Officer of LivaNova. “Our follow-on analyses of the RECOVER unipolar data demonstrate that symptoms alone may not be the sole source upon which to gauge the clinical impact of treatment. Instead, symptoms, function, and quality of life taken together present a more complete picture of treatment effectiveness. We are eager to review this powerful data with CMS during the reconsideration process.”

Final Articles in Critical Series Analyze RECOVER Primary and Select Secondary Endpoint Data

Two new in-depth analyses^1,2 on primary and select secondary endpoints in the RECOVER trial have recently been published and a third accepted by peer-reviewed journals. Prior to these articles, two initial articles were published in Brain Stimulation^3,4 in December 2024, completing the series of five critical articles in total.

Collectively, the articles highlight the significant unmet need of this markedly ill population with TRD. The RECOVER data demonstrates that VNS Therapy improves symptoms, function, and quality of life in TRD patients over time. These are outcome measures identified as clinically relevant by CMS. Depressive symptoms, daily function, and quality of life taken together, as a novel composite metric, present a more complete picture of treatment effectiveness than symptoms alone. The fifth and final critical publication utilizes this composite metric and demonstrates favorable response to VNS Therapy in TRD patients who had previously failed multiple treatments, including interventional therapies. Researchers found that patients with previous ECT or TMS treatment had statistically significant and clinically meaningful benefits with active VNS Therapy. Notably, VNS Therapy is the only treatment that has demonstrated therapeutic effects in patients who previously failed ECT.

24-Month VNS Therapy Data Show Durability, Increasing Response Across All Outcome Measures

New top-line 24-month data from the RECOVER study show that, across all outcome measures, VNS Therapy patients in the active arm of RECOVER experienced a substantial durability of benefit from month 12 to month 24. Of those patients who at 12 months had achieved clinically meaningful benefit, the median durability of benefit was 81.3% across all outcome measures at the 24-month assessment. This is considerable durability for these unipolar patients who, at baseline in the RECOVER study, had failed more than 13 antidepressant treatments on average.

Observing all VNS Therapy patients in the active treatment arm of the RECOVER trial from month 12 to month 24, researchers also found improvement in all outcome measures, with the median rate of response, or clinically meaningful benefit, increasing from 40.2% at month 12 to 51.6% at month 24.

“There is no clinical evidence to demonstrate that there are any other therapies, including pharmacotherapies and interventional therapies such as electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS), that can claim this profound level of sustained durability and increasing benefit,” said A. John Rush, M.D., Professor Emeritus at Duke-National University of Singapore Medical School who has spent 25 years researching VNS Therapy for TRD and served as Chief Consultant on the RECOVER trial. “These are critical findings that offer hope to treatment-resistant depression patients and their loved ones, who have struggled for years to find effective options. Patients not only stay better – they also continue to get better.”

Improvement in suicidality shows statistically significant separation as early as month three

LivaNova conducted additional in-depth analyses specifically evaluating suicidality for the active treatment arm of RECOVER through the first 12 months of therapy. Using a composite suicidality measure⁵, results showed an estimated 43% higher odds of achieving meaningful improvement in suicidal ideation symptoms versus the control arm. Of specific interest, there was separation between the active and control arms on the composite suicidality metric as early as month three. Additionally, the observed separation was consistent throughout the initial 12 months.

“The composite suicidality outcome is especially encouraging because we can see a separation between the active and control arms so early in the study,” said Charles Conway, M.D., director of the Washington University Resistant Mood Disorders Center at Washington University School of Medicine in St. Louis. Conway is the RECOVER study’s lead investigator. “We’re eager to further evaluate the suicidality data beyond 12 months and, in the context of the overall durability story of VNS Therapy, determine whether this benefit also continues to improve over time.”

While not included in the initial submission to CMS, the suicidality data will be provided in detail to the agency upon publication in a peer-reviewed journal.

RECOVER launched in 2019 as part of a CED framework per the CMS NCD process. For the unipolar cohort of RECOVER, enrollment was completed in March 2023, and the 12-month follow-up for those patients was completed in March 2024. No new safety issues were identified in the study.

About RECOVER

LivaNova’s VNS Therapy™ System has been approved for the treatment of depression since earning CE Mark in 2001 and premarket approval (PMA) from the U.S. Food and Drug Administration in 2005. RECOVER stands for A Prospective, Multi-center, Randomized Controlled Blinded Trial Demonstrating the Safety and Effectiveness of VNS Therapy System as Adjunctive Therapy Versus a No Stimulation Control in Subjects With Treatment-Resistant Depression.

The largest randomized clinical study of its kind, RECOVER is examining up to 1,000 patients ages 18 or older who have unipolar or bipolar depression that is difficult to treat. A total of 493 adults with at least four documented unsuccessful attempts with antidepressant treatments participated in the unipolar cohort of the RECOVER study. The double-blind, randomized controlled study is assessing how VNS Therapy can offer patients relief from their depressive symptoms and improve quality of life. It is being carried out at up to 100 leading hospitals and medical centers across the United States.

About VNS Therapy for Depression

The VNS Therapy™ System, Symmetry™, is U.S. Food and Drug Administration-approved and indicated in the U.S. for the adjunctive long-term treatment of chronic or recurrent depression for patients 18 years of age or older who are experiencing a major depressive episode and have not had an adequate response to four or more adequate antidepressant treatments. The most commonly reported side effects are voice alteration or hoarseness, prickling or tingling in the skin, increased coughing, shortness of breath, and sore throat. Infection is the most common complication of the surgical procedure. Important safety information is available at www.livanova.com/depression/en-us/safety-information.
