LivaNova Announces Publication Detailing the Design of the RECOVER Clinical Study Evaluating VNS Therapy for Treatment-Resistant Depression

Jul 07, 2020

LONDON--(BUSINESS WIRE)--Jul. 7, 2020-- LivaNova PLC (NASDAQ:LIVN), a market-leading medical technology and innovation company, today announced a publication in Contemporary Clinical Trials1, which details the design 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” or the RECOVER clinical study. RECOVER is currently under way as part of a Coverage with Evidence Development framework of the U.S. Centers for Medicare & Medicaid Services’ (CMS) National Coverage Determination process.

“VNS Therapy for treatment-resistant depression has proven to be a safe and effective adjunctive treatment that significantly improves patients’ response and remission rates in this chronically ill population that is difficult to treat,” said Dr. Charles R. Conway, Director of the Washington University Resistant Mood Disorders Center, who serves as Principal Investigator for RECOVER. “As we continue to gain momentum and recruit patients for this important research, we are pleased to share more detailed information on this ground-breaking study, with the goal of raising awareness among clinicians and patients who could benefit from VNS Therapy.”

Major Depressive Disorder (MDD) is a leading cause of disability, morbidity and mortality worldwide.2 Even after four adequate courses of antidepressant treatment, one in three patients are left with depressive symptoms that significantly impact their daily functioning.3 The objectives of the RECOVER study are to confirm, in a randomized controlled blinded trial, the outcomes previously observed and published in a large registry4 – that VNS Therapy has a significant positive effect on baseline depressive symptom severity for patients with treatment-resistant depression (TRD).

“Working with CMS, we designed RECOVER – the largest clinical study of its kind – to further evaluate and confirm the efficacy of VNS Therapy for TRD,” said Bryan Olin, LivaNova Senior Vice President for Clinical, Quality and Regulatory Affairs. “The goal of the RECOVER study is to strengthen the results reported in previous studies, facilitating a positive National Coverage Determination that improves access to VNS Therapy for TRD patients who do not respond to other antidepressant therapies, potentially transforming their quality of life.”

About VNS Therapy for Depression

The VNS Therapy System, Symmetry™, is indicated 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. Commonly reported side effects are hoarseness, shortness of breath, sore throat and coughing. Side effects typically only occur during stimulation and are less noticeable over time.
