Medtronic plc (NYSE:MDT), a global leader in healthcare technology, today announced findings from a new study of the Patient Preferences for the Treatment of Hypertension.
New data from Medtronic Patient Preference study presented at TCT 2021; Medtronic adds to its clinical leadership for renal denervation with launch of the SPYRAL AFFIRM study DUBLIN and ORLANDO, Fla., Nov. 4, 2021 /PRNewswire/ -- Medtronic plc (NYSE:MDT), a global leader in healthcare technology, today announced findings from a new study of the Patient Preferences for the Treatment of Hypertension. The findings will be presented later today during the “What’s Novel in Interventional Hypertension session” at the 33rd Transcatheter Cardiovascular Therapeutics (TCT 2021) conference, the annual scientific symposium of the Cardiovascular Research Foundation. Medtronic also announced the initiation of the SPYRAL AFFIRM study, evaluating the long-term safety, efficacy, and durability of the Medtronic Symplicity™ Renal Denervation System in real-world patients with uncontrolled hypertension and comorbidities such as diabetes, isolated systolic hypertension, and chronic kidney disease. Patient Preference in the Treatment of Hypertension: Interventional Treatments and Standard of Care The study found that in exchange for treatment risks, patients on average would require a minimal acceptable benefit of less than 2.5mmHg reduction in office-based systolic blood pressure. Additionally, on average, patients indicated a tolerance of at least 20% risk of adverse events (such as a vascular injury or drug side effects) in exchange for being able to lower their office-based systolic blood pressure. These findings suggest that despite the risks of an intervention, patients may accept lower blood pressure reductions than those observed in published literature of Medtronic Symplicity Spyral Renal Denervation procedure1,2. Additionally, patients may be willing to tolerate risks higher than those observed in peer-reviewed published studies3 of Symplicity Spyral. The study also concluded that blood pressure reduction was the most important driver of patient preference over all other attributes like medication burden and treatment (including interventional treatment-related) risks. When applying this model to a patient population who is interested in an interventional procedure without medication, up to 76.5% of patients would be willing to consider an interventional approach such as RDN if they achieve a 10mmHg reduction in office-based systolic blood pressure. Including the maximum acceptable risk of 20%:
“This novel, patient preference study is particularly valuable for a new procedure like renal denervation, because it demonstrates that for patients, lowering blood pressure, even by a small amount, is meaningful,” said Dr. Michael Weber, professor of cardiovascular medicine at State University of New York, Downstate Medical Center. “For the first time, these results give us quantitative insights into hypertension treatment preferences - importantly, patients are very open to considering a medical intervention procedure, such as RDN, with demonstrated improvements in the control of their high blood pressure.” The study, which was designed based on the FDA Guidance for Patient Preference Information, surveyed 400 individuals in the U.S. who have high blood pressure (physician confirmed systolic office-based blood pressure greater than 140 mmHg), who were on up to three anti-hypertensive medications and were not previously involved in a SPYRAL HTN study. The study uses a statistical method called a discrete choice experiment, often used to compare individuals’ preferences among two or more alternatives. “The patient preference insights, combined with the breadth of real world and randomized sham controlled trials we have for renal denervation, are aligned with the recent clinical consensus from the European Society of Hypertension, Society for Cardiovascular Angiography and Interventions, and National Kidney Foundation that reinforce RDN as a potential treatment option for patients,” said Jason Weidman, senior vice president and president of the Coronary & Renal Denervation business, which is part of the Cardiovascular Portfolio at Medtronic. “Patient preference data will be important to help physicians understand patients’ acceptable benefits and risks related to minimally invasive procedures for the treatment of hypertension.” SPYRAL AFFIRM Study Launch “Through the strong investment in our clinical program, the AFFIRM study will expand RDN research into a variety of patient groups,” said Weidman. “The AFFIRM clinical study adds to our body of evidence for RDN and will help us further answer questions about the use of this procedure in more complex, real world patients such as those with isolated systolic hypertension, diabetes and chronic kidney disease.” The SPYRAL AFFIRM clinical study is part of the SPYRAL HTN Global Clinical Program, adding to the safety and efficacy data for RDN. Along with the real-world data from the Global Symplicity Registry,4 when combined with commercial experience, there have been more than 20,000 procedures performed with Medtronic RDN technology. The clinical program is backed by the most rigorous and extensive patient experience studied in the presence2 and absence1 of medication and in patients with high baseline cardiovascular risk.4 About the Medtronic Symplicity™ Renal Denervation System About Medtronic Any forward-looking statements are subject to risks and uncertainties such as those described in Medtronic’s periodic reports on file with the Securities and Exchange Commission.
