Endotronix Receives IDE Approval for the Market Expanding PROACTIVE-HF 2 Clinical Trial

The PROACTIVE-HF 2 trial is designed to expand access to NYHA class II patients and to scale pulmonary artery pressure-guided therapy with the Cordella Sensor
In addition, the Company presented positive 12-month clinical data on a subset of patients in its pivotal PROACTIVE-HF clinical trial at the annual Heart Failure Society of America (HFSA) conference

NAPERVILLE, Ill., Oct. 9, 2023 /PRNewswire/ -- Endotronix, Inc., a digital health and medical technology company dedicated to advancing the treatment of heart failure (HF), announced it has received Investigational Device Exemption (IDE) approval from the FDA for a subsequent multicenter study, PROACTIVE-HF 2, which will evaluate the company's Cordella Sensor for pulmonary artery (PA) pressure-guided therapy. The prospective, dual-arm trial aims to expand access to New York Heart Association (NYHA) class II HF patients and support efficient and scalable remote patient management with a clinician-directed, patient self-management strategy.

Endotronix announced FDA approval for the PROACTIVE-HF 2 IDE trial with the Cordella Sensor to expand market access and shared positive results from a substudy of their pivotal PROACTIVE-HF clinical trial. The company plans to share full results from the PROACTIVE-HF trial next year.

"The evidence in favor of PA pressure-guided therapy for NYHA class III HF patients has been consistently validated over the last 15 years. However, questions remain as to the therapy benefit in NYHA class II patients and how to best scale effective remote HF management," stated Lynne W. Stevenson M.D., Heart Failure Specialist at Vanderbilt University Medical Center in Nashville, TN, and Global Principal Investigator (PI) of the PROACTIVE-HF 2 clinical trial. "The randomized arm of PROACTIVE-HF 2 will be the first study to compare PA pressure-guided therapy to a telehealth control arm. The single-arm cohort evaluates the power of engaged patients and subsequent impact on outcomes. Together these studies help us better understand the impact of pulmonary hypertension on right ventricular function over time and provide guidance on how to scale this important therapy with patient engagement."

The PROACTIVE-HF 2 prospective, open-label randomized controlled clinical trial will enroll up to 1,500 patients in the U.S. and Europe. The dual arm study design was presented over the weekend at HFSA and the first patient is expected to be enrolled later this year. The randomized arm will assess the safety and efficacy of PA pressure-guided therapy using Cordella in NYHA class II patients at risk for congestion. In both cohorts, patients and clinicians will have access to daily trended telehealth data (i.e. blood pressure, heart rate, and weight) and the treatment cohort will also have access to daily PA pressure data. The study will evaluate safety and efficacy, using a compositive first HF event or death rate, for up to 24 months. The single-arm study will assess the impact of clinician-directed patient self-management at home in NYHA class III HF patients who are at risk for poor outcomes using a 12-month endpoint for safety and incidence of HF hospitalization or death. Both arms will collect data on secondary endpoints including changes in right ventricular function in relation to PA pressure, and patient engagement.

Additionally, the Company presented 12-month sub-study data from its initial pivotal PROACTIVE-HF trial at the HFSA conference, demonstrating a low HF hospitalization rate of 0.34 at 12 months in NYHA class III HF patients. In December 2021, the prospective, multi-center pivotal PROACTIVE-HF trial was redesigned from a randomized controlled trial, with patients and providers in a control arm blinded to PA pressure values, to a single-arm study where both groups had access to patient data. The data for 63 former control arm patients was evaluated before and during the 12-month period following the unblinding, demonstrating significant improvements in mean PA pressure (mPAP) and outcomes, as well as strong patient interest in having access to PA pressure data.

In the unblinded period, average seated mPAP for patients above target (>20 mmHg) decreased significantly (28.1 mmHg vs. 23.6 mmHg, p=0.03)
12-month unblinded HF hospitalization rate was significantly lower than the 12 months prior to implant (0.3 ±0.9 vs. 1.3±0.9, p<0.0001)
78% of patients made lifestyle changes based on their mPAP trends
86% of patients rated a positive impact of PA pressure management on their health

This data dovetails the announcement that the PROACTIVE-HF study has completed its primary endpoint follow-up period and the data is being prepared for pre-market approval (PMA) submission to the FDA by the end of the year and data presentation in the first half of next year.

"We are establishing a strong foundation of compelling clinical evidence for Cordella with early PROACTIVE-HF data. The team is driving towards PMA submission before the end of this year and looks forward to sharing the results from the full study cohort in 2024," commented Harry Rowland, CEO and co-founder of Endotronix. "We remain confident in the benefits Cordella brings to patients and clinicians to improve heart failure outcomes and remain on track for a mid-2024 launch."

About Endotronix
Endotronix innovates at the intersection of Medtech & Digital Health to improve care for people living with heart failure (HF). The comprehensive Cordella solution enables proactive, data-driven HF management that engages patients, reduces and prevents congestion, and improves outcomes. The Cordella Sensor is an implantable pulmonary artery (PA) pressure sensor that directly measures the leading indicator of congestion, allowing early, targeted therapy. The Cordella HF System is a patient health management platform, which combines comprehensive vital sign data from non-invasive devices to support patient-clinician engagement and care decisions. Combining trended insights, the versatile and scalable Cordella enhances current clinical practice and supports guideline-based care across the entire HF continuum. Learn more at www.endotronix.com.

The Cordella PA Pressure Sensor System is an investigational device and is not currently approved for clinical use in any geography. CAUTION – Investigational Device. Limited by Federal (or United States) Law to Investigational Use. Exclusively for Clinical Investigation. The Cordella HF System, without the sensor, is available for commercial use in the U.S. and E.U.
