Late-breaking results presented at the European Society of Cardiology’s Heart Failure Association annual conference and simultaneously published online in the European Journal of Heart Failure

SANTA CLARA, Calif., May 23, 2022 /PRNewswire/ — Axon Therapies, a private company focused on addressing a root cause of heart failure, today announced positive early results from a roll-in cohort for their feasibility IDE trial, REBALANCE-HF. The study is evaluating a novel frontline therapy called Splanchnic Ablation for Volume Management (SAVM) that aims to rebalance volume distribution in heart failure patients with preserved ejection fraction (HFpEF). The results support safety and efficacy of the SAVM procedure and signaled clinical improvements in key data including pulmonary capillary wedge pressure (PCWP) with exercise and patient quality of life metrics. Data was presented at the European Society of Cardiology’s Heart Failure Association 2022 annual conference in Madrid, Spain and simultaneously published online in the European Journal of Heart Failure.

“It is very promising to see the positive early dataset and improvement in key clinical outcomes.  HFpEF patients have few treatment options today, and SAVM offers a minimally invasive, implant-free procedure designed to treat a root cause of their symptoms and hopefully slow down or stop disease progression – it has the potential to be a very exciting approach,” commented Marat Fudim, MD, Advanced Heart Failure Specialist at Duke University Medical Center. “I’m eager to see the longer-term results and patient outcomes from the study as they become available.”

The REBALANCE-HF study is a prospective, multi-center, randomized, sham controlled, double-blinded study enrolling 80 patients at up to 20 U.S. sites and is designed to assess the safety and efficacy of the SAVM procedure. The trial included a cohort of 18 single-arm, open-label roll-in patients for interim analysis that provided early data on the SAVM procedure using the Axon Ablation Catheter. While the findings require additional confirmation, early results are very promising. The therapy had a solid safety profile—all patients were successfully treated and three non-serious device-related adverse events were reported (heart failure decompensation requiring an ER visit, transient hypertension during the procedure, and back pain following the procedure). Patients showed improvement in PCWP with exercise as well as improvements in functional capacity, symptoms, and overall health status.

Key Results

  • Significant reduction in PCWP at 20 watts and peak exercise at 1-month (p=0.007 and p=0.013, respectively)
  • 33% of patients experienced improvement of at least one New York Heart Association (NYHA) class compared to baseline at 1-month (p<0.01)
  • Significant improvement in Kansas City Cardiomyopathy Questionnaire (KCCQ) (22.1 pts at 1-month, p <0.01; 18.3 pts at 3-months, p<0.01)

Sanjiv Shah, MD, who is the National Principal Investigator of the REBALANCE-HF trial, stated, “The SAVM procedure offers a novel approach to potentially improving outcomes in patients suffering from heart failure by reducing sympathetic nerve activity to restore volume balance within the circulation. The early data from the REBALANCE-HF trial, demonstrates the potential promise and importance of managing volume shifts in this underserved patient population.” Dr. Shah is Director of Research for the Bluhm Cardiovascular Institute at Northwestern University Feinberg School of Medicine in Chicago, Illinois.

“The data for this first cohort of patients is very encouraging. We anticipate completing enrollment in REBALANCE-HF later this year and sharing the full results next year,” stated Chad Hoskins, CEO of Axon Therapies. “The data builds on the results of our pilot studies, which demonstrated a durable effect of SAVM at 1 year. We’re grateful for the work of our investigators, and we look forward to the culmination of these efforts in a pivotal trial beginning in 2023.”

Miracor Medical starts 2nd randomized study, targeting expanded indications. 300 patients have been treated with PiCSO®

Below, we are re-publishing with permission the press-release issued by Miracor Medical on March 29, 2022

AWANS, Belgium, March 29, 2022 /PRNewswire/ — Miracor Medical SA (Miracor Medical) today announced the first patient enrolled in the PICSO-AMI-V study to evaluate the benefits of PiCSO® (Pressure Controlled Intermittent Coronary Sinus Occlusion) therapy as an adjunct to conventional primary percutaneous coronary intervention (PCI) for patients presenting with inferior ST-Elevation Myocardial Infarction (STEMI).

The first patient enrolled was treated at the University Hospital of Toulouse, France by the team of Professor Didier Carrié (Drs T. Lhermusier and F. Campelo). “Our team started using the PiCSO therapy for anterior STEMI patients in 2021. We are delighted to explore new indications and now start using PiCSO for inferior STEMI patients in the context of the PiCSO-AMI-V study,” says Prof. Carrié.

Improving outcomes for patients with large heart attacks remains an important unmet need

The principal investigator of the study is Professor Adrian Banning, Oxford Heart Center, Oxford, UK. “We are pleased to be initiating the PiCSO-AMI-V study. It will explore the potential for PiCSO therapy to improve the outcomes of patients with heart attacks affecting the inferior side of the heart. The study builds upon the data from the First-In-Man study that we published in 20213. We know that improving outcomes for patients with large heart attacks remains an important unmet need, especially because these patients often progress to develop heart failure.” says Prof. Banning.

PICSO-AMI-V is a prospective, randomized, multicenter feasibility study and will enroll 75 inferior STEMI patients presenting with TIMI 0 & 1 flow, at up to 10 clinical sites in Europe. In the study, patients will be randomized 2:1 to a group receiving PiCSO as an adjunct to their primary PCI procedure versus a conventional strategy of primary PCI alone. Adverse Device Effect (ADE) rate at 30 days post index procedure will be assessed as the primary endpoint. In addition, cardiac function and clinical safety endpoints – including death, heart failure-related hospitalization, new onset or worsening of heart failure – will be assessed. The patients will be followed for 1 year.

PiCSO therapy has demonstrated positive results in several clinical studies. Data from two recent studies (“PiCSO in ACS” and “OxAMI-PICSO”) showed that the use of the PiCSO Impulse System is associated with a significant infarct size reduction in anterior STEMI patients 1,2. Furthermore, OxAMI-PICSO3 showed an early improvement in coronary microvascular function post PiCSO treatment in both anterior and inferior STEMI patients. PiCSO therapy accelerates the microcirculatory recovery resulting in significantly lower IMR (Index of Microcirculatory Resistance) and RRR (Resistive Reserve Ratio) post procedure when compared with controls.

We are thrilled to start this second randomized clinical trial in Europe, and to progress our strategy to expand indications beyond our initial indication of anterior STEMI. The PiCSO-AMI-V Inferior STEMI study will complement the ongoing PiCSO-AMI-I (Anterior STEMI) study, which has enrolled more than 100 anterior STEMI patients and is anticipated to complete enrollment during the second semester of this year. We also recently treated the 300th patient with the PiCSO therapy, illustrating the acceleration of usage and experience with the therapy,” says Olivier Delporte, CEO of Miracor Medical.

PiCSO therapy is used during the primary PCI procedure in acute myocardial infarct (AMI). Via its unique differentiated mechanism of action the PiCSO Impulse System clears the coronary microcirculation by intermittently occluding the coronary sinus outflow. The use of the PiCSO Impulse System has been associated with a reduction in infarct size after STEMI, which has been shown to lead to reductions in heart failure hospitalizations and reduced mortality4. Heart Failure develops in 18-28% of patients 90 days after their STEMI 5.

The PiCSO-AMI-V Inferior STEMI study is partially funded by a recoverable cash advance granted by the Walloon Region to Miracor Medical.

Clinical Accelerator announces collaboration with Verve Medical to conduct an early human feasibility study for treatment-resistant hypertension

Clinical Accelerator, a full-service contract research organization, is pleased to announce that it has entered into a collaboration with Verve Medical, to conduct an early human feasibility study of their novel medical device for patients with treatment-resistant hypertension.

World-wide, there are over a billion patients who suffer from hypertension and it is directly responsible for millions of deaths annually. Many patients with hypertension are either inadequately identified or treated and medications can be expensive and have side effects. Verve Medical is focused on proving an effective peri-pelvic renal denervation approach to hypertension which, unlike the peri-arterial approach, avoids the possibility of arterial restenosis and does not require anticoagulation or antiplatelet agents. This device has the ability to achieve an immediate blood pressure drop in patients that is comparable to open sympathectomy.

Clinical Accelerator is very excited to partner in this project and will be working closely with Verve Medical, running their early human feasibility study in our region of operation. We look forward to developing this product and achieving positive data on this potentially life-changing device.

Below, we are re-publishing with permission the press-release issued by Anteris Technologies Ltd on January 24, 2022

Brisbane, Australia and Minneapolis, USA, Anteris Technologies Ltd (ASX: AVR) reports the first-in-human DurAVR™ THV study met or exceeded its interim study objectives.
At the 30-day follow up point, the first five patients of the planned 10-patient study showed:

• All five subjects continued to do well with no reported adverse events (no death, stroke, myocardial infarction, reintervention).
• An average 86% improvement in mean gradient (standard measure of stenosis severity) from pre-treatment levels.
• Mean gradients were up to 50% lower than other TAVR devices when matched to annular size.1 All patients are in the normal or near normal range when compared to the general population with normal valve function.
• Average Effective Orifice Area (EOA) was up to 45% larger than those reported with other TAVR devices in matched annular sizes.2
• No conduction (heart rhythm) disturbances due to the procedure.
• No clinically significant paravalvular regurgitation despite very complex and heavily calcified anatomy.
• Echocardiographic and CT analysis reported normal leaflet mobility, no leaflet calcification or thrombus generation.
• Echocardiographic and CT imaging data showed consistent laminar flow throughout the valve and long coaptation length in all five patients. Ostensibly, these features indicate lower leaflet strain leading to long term durability.
• The system also allowed for excellent commissural alignment; a significant patient benefit if future coronary intervention were required.
• A 20% increase from baseline in 6 min walk test (a measure of patient exercise tolerance). This is a 170% greater improvement than observed in studies of other TAVR valves.3 This indicates a marked improvement in patients’ functional status and exercise tolerance. The improvement in exercise capacity may be associated with the increased EOA (larger valve opening area due to its unique design) allowing optimal haemodynamics (blood flow) at rest and during exercise.4 Exercise performance is a critical marker of cardiac health.

Dr. Paul Sorajja, an interventional cardiologist at Abbott Northwestern Hospital and one of the implanting physicians in this trial commented, “Due to its unique leaflet design, DurAVR™ continues to provide superior haemodynamics with a balloon expandable platform”.

Dr. Vinnie Bapat, a cardiothoracic surgeon at the Minneapolis Heart Institute and another member of the team of implanting physicians in the trial stated, “DurAVR™ has been rationally engineered to provide ease of implantation of the valve for the doctor, immediate haemodynamic benefit for the patient post-implantation, and the potential to provide a long-term durable effect which is of utmost importance when treating younger, low-risk patients. We are happy to see the patients on this trial doing so well with such impressive haemodynamic improvement, and are looking forward to enrolling the rest of the trial imminently”.

“DurAVRTM continues to exceed very high expectations in a complex group of bicuspid and tricuspid patients. The haemodynamic performance as well as valve function is remarkable. Additionally, the lack of any conduction change (arrhythmia) across five patients is a testament to the engineering team’s ingenuity and focus on improving all aspects of TAVR for patients. All signs continue to point to success in our mission of making available a TAVR that works better from the get-go and lasts longer,” Anteris Chief Medical Officer, TAVR interventionalist Dr Chris Meduri (the study leader), commented.

“The excellent results observed so far are a function of the proprietary 3D single-piece leaflet design of DurAVR™ that mimics a native aortic valve. These numbers are even more remarkable considering this cohort had small annular anatomy. Furthermore, patients’ functional status improved as did their exercise performance indicating early improvements in quality-of-life due to receiving DurAVR™. As the mean age of patients in this study is 73 this improvement in exercise performance is incredibly important and supports the use of DurAVR™ in this more active patient group who require a valve that lasts longer and works better than current solutions. The current data represents a small number of patients and should be viewed as such. However, we look forward to continuing the study with the next cohort as well as recruiting patients for our FDA IDE study and reporting more results during 2022,” Anteris CEO Wayne Paterson said.

Sequana Medical announces positive interim results of SAHARA DESERT, the alfapump DSR® study in heart failure patients with persistent congestion

Below, we are re-publishing with permission the press-release issued by Sequana Medical NV on December 07, 2021

The alfapump® system © SEQUANA MEDICAL NV
  • Interim data from six patients indicate that alfapump DSR therapy can:
    • safely, effectively and rapidly eliminate persistent congestion and restore euvolemia in diuretic-resistant heart failure patients,
    • considerably benefit cardio-renal status, and
    • dramatically improve diuretic responsiveness for months post-treatment
  • Recruitment on-track to report top-line data in H2 2022
  • Long-term follow-up of RED DESERT patients shows durable improvement in diuretic response following alfapump DSR therapy
  • Proprietary DSR Infusate 2.0 development on track to start MOJAVE DESERT in H2 2022

Ghent, Belgium – 7 December 2021 – Sequana Medical NV (Euronext Brussels: SEQUA, the “Company” or Sequana Medical), an innovator in the treatment of diuretic-resistant fluid overload in liver disease, malignant ascites and heart failure, today announces positive interim results from six patients in SAHARA DESERT, the safety and feasibility study of alfapump DSR (Direct Sodium Removal) in heart failure patients with persistent congestion.

Ian Crosbie, Chief Executive Officer at Sequana Medical, commented: “We are extremely pleased with these interim results from SAHARA DESERT which, for the first time, indicate the ability of repeated DSR therapy to safely, effectively and rapidly eliminate persistent congestion in decompensated heart failure patients. Just as we showed in RED DESERT, we are able to achieve this, together with a major improvement in patients’ diuretic-response. It is promising to see the improved cardio-renal status of these patients compared to the status expected for patients undergoing volume removal. We look forward to the completion of enrolment to report on top-line data and the planned commencement of MOJAVE DESERT, our first U.S. DSR study, in H2 2022. The long-term follow-up data from our RED DESERT patients is very encouraging, indicating the sustained improvement in diuretic response as demonstrated by a clear reduction in the need for loop diuretics. This further indicates how powerful and versatile our alfapump DSR platform is and how it can address clear unmet medical needs within this large and growing patient population.”

Strong interim results from SAHARA DESERT

All six patients evaluated for the interim analysis had severe heart failure at baseline (mean left ventricle ejection fraction percentage in low 20’s and mean NT-proBNP of > 6,000 pg/ml), with persistent congestion despite being on high dose loop diuretics (mean furosemide equivalent dose of approx. 250 mg per day). Out of the six patients in the interim analysis, one patient had completed phase 2 of the study, three patients were in phase 2 and two patients were in phase 1.

After intensive alfapump DSR therapy in phase 1, patients had a mean weight loss of approx. 6kg or 7% of their body weight vs. baseline and all patients achieved euvolemia without the need of any loop diuretics. These interim data also showed a near normalisation of diuretic response with six-hour excretion of sodium more than doubling vs. baseline, as well as an improvement in NT-proBNP, a key cardiac function parameter, with a mean reduction of more than 30% vs. baseline. The mean eGFR (estimated Glomerular Filtration Rate) and creatinine after completion of phase 1 (active fluid removal) was similar to baseline, which is remarkable since worsening in kidney function during significant volume removal is the expectation in severely ill diuretic-resistant patients such as these. Patients who completed phase 1 are at less than 10% of their baseline loop diuretic dose (n=4, mean time post end of phase 1 is three months).

Serial alfapump DSR therapy was safe and well tolerated with few adverse events and there were no clinically significant changes in serum sodium levels or other electrolytes observed in these six patients after intensive DSR therapy.

To date, nine patients have been enrolled at two centers in SAHARA DESERT and implanted with the alfapump DSR system, of which six patients were evaluated for this interim analysis and two more patients just started study treatment. One additional patient was enrolled but died due to a cardiac arrest three days after study initiation. The death was deemed by the site unrelated to the study therapy, procedure or device; the Data Monitoring Committee assessed the event as possibly related to the study therapy but not related to the procedure or device. Patient enrollment continues as planned and reporting of top-line data is expected in H2 2022.

Dr. Jeffrey Testani, Associate Professor at Yale University and Heart Failure Scientific Advisor of Sequana Medical, commented: “These interim results are highly encouraging and could potentially provide a course of therapy for severely ill diuretic-resistant heart failure patients with persistent congestion where alternative treatment options are currently exceedingly limited. We are looking forward to completing the study and presenting the top-line data of all patients by the end of next year.”

Dr. Oliver Gödje, Chief Medical Officer at Sequana Medical, added: “SAHARA DESERT represents the continuing development of our alfapump DSR therapy, and the interim results are a further indication of its unique capabilities. Our RED DESERT study showed that alfapump DSR could improve the diuretic response and cardio-renal status in patients with diuretic-resistant heart failure. SAHARA DESERT is building on these strong results as we focus on our anticipated patient population, those heart failure patients with persistent congestion, for whom oral diuretics is no longer effective at preventing fluid overload, a patient population particularly difficult to manage by healthcare professionals and where alfapump DSR could offer a real change in the treatment paradigm.”

Long-term follow-up of RED DESERT patients demonstrates sustained improvement of diuretic response

In May 2021, Sequana Medical reported strong top-line results of RED DESERT (NCT04116034) in seven euvolemic heart failure patients on high dose diuretics. Following the six-week study, patients continued to be followed for up to 19 months. One patient died nine months after the end of the study (unrelated to DSR therapy). All patients had a reduction in their oral loop diuretic dose ranging from 40% to 96% at their last visit within the follow-up period (9-19 months after last DSR treatment in the study), showing a significant durability to the improvement in diuretic responsiveness following alfapump DSR therapy.

Strong progress in development of proprietary DSR Infusate 2.0

A key element of Sequana Medical’s DSR programme is the development of the proprietary DSR Infusate 2.0, to deliver an infusate with a superior therapeutic profile as well as a high margin recurring revenue stream to accompany alfapump sales. Chemistry, Manufacturing and Controls (CMC) of DSR Infusate 2.0 is progressing well and pre-clinical development work is on track. The MOJAVE DESERT study, the first U.S. study of short-term DSR therapy in chronic heart failure patients with persistent congestion, is planned to start in H2 2022.

About SAHARA DESERT – alfapump DSR study in decompensated heart failure patients

SAHARA DESERT is a multi-centre, prospective, randomised, open-label study to evaluate the safety and feasibility of alfapump DSR® therapy in heart failure patients with persistent congestion and resistance to loop diuretic treatment. Twenty patients will be implanted with the alfapump DSR system. Following alfapump DSR implantation, patients undergo a diuretic challenge to quantify their response to diuretics, which is repeated at specific time points throughout the study. At the start of the study treatment period, loop diuretics are withheld, and patients are randomised 1:1 to DSR therapy with or without SGLT2-inhibitor to evaluate their impact on DSR therapy. Patients undergo intensive DSR therapy with DSR D10% infusate for two weeks (phase 1) which can be repeated up to two times depending on patients’ euvolemic state, diuretic response and stable DSR dosing at the end of phase 1. Patients who have achieved euvolemia and have adequate diuretic response enter the maintenance DSR treatment phase with monthly DSR dosing for 16 weeks (phase 2).

The primary safety and tolerability endpoints include the rate of treatment-, device- or procedure-related serious adverse events through the end of the maintenance phase. Secondary feasibility endpoints include the ability of DSR therapy to restore and maintain euvolemia without the need for additional loop diuretic treatment. Additional exploratory endpoints will evaluate the potential impact of SGLT-2 inhibitors on DSR therapy. The study is being conducted in up to three clinical centres in the Republic of Georgia. For more information about the study, please visit (NCT04882358).

About alfapump DSR in heart failure patients with diuretic-resistant congestion

alfapump DSR® is in clinical development as potential long-term treatment for heart failure patients with diuretic-resistant congestion. Congestion, also known as fluid overload, is the driver of more than 90% of the one million heart failure hospitalisations in the U.S. each year (which in total account for $13 billion in costs). The treatment options are severely limited in those patients for whom diuretics are no longer effective, which is evident from the 24% hospital re-admission rate at 30 days from discharge. Persistent congestion and worsening renal function is a key indicator of increased mortality in acute decompensated heart failure patients.

Sequana Medical’s proprietary DSR therapy is a unique approach that removes sodium from the body using diffusion in the peritoneal cavity with the use of a sodium-free solution (the “DSR infusate”). Once the sodium has been removed, the body eliminates excess fluid naturally through osmotic ultrafiltration and urination to restore the serum sodium concentration. alfapump DSR combines DSR therapy with the proven alfapump to deliver a fully implanted system for long-term DSR therapy. Strong top-line results from the RED DESERT study showed that repeated dose alfapump DSR therapy in diuretic-resistant heart failure patients is highly effective at managing the fluid and sodium balance and improves cardio-renal status. Following the six-week study, there was a dramatic improvement in patients’ diuretic response and a meaningful long-term reduction in their oral loop diuretic needs.

About Sequana Medical

Sequana Medical is a commercial stage medical device company utilizing its proprietary alfapump® and DSR® (Direct Sodium Removal) technologies to develop innovative treatments for fluid overload in liver disease, malignant ascites and heart failure where diuretics are no longer effective. Fluid overload is a frequent complication of many large diseases – including advanced liver disease driven by NASH (non-alcoholic steatohepatitis)-related cirrhosis and heart failure – with diuretic resistance being widespread. The U.S. market for the alfapump resulting from NASH-related cirrhosis is forecast to exceed €3 billion annually within the next 10-20 years. The heart failure market for DSR and the alfapump DSR® is estimated to be over €5 billion annually in the U.S. and EU5 by 2026.

The alfapump is Sequana Medical’s unique, fully implanted wireless device that automatically pumps fluid from the abdominal cavity into the bladder, where it is naturally eliminated through urination. DSR is Sequana Medical’s proprietary approach to managing sodium and fluid overload through use of a sodium-free infusate administered into the abdominal cavity.

In the U.S., the Company’s key growth market, the alfapump has been granted breakthrough device designation by the FDA for recurrent or refractory ascites due to liver cirrhosis. Interim data from the ongoing North American pivotal study (POSEIDON) showed positive outcomes against all primary endpoints of the study and a rapid and persistent clinically important improvement in quality of life. This study is intended to support a future marketing application of the alfapump in the U.S. and Canada. Completion of enrolment was announced in December 2021 and the primary endpoint reporting is planned for Q4 2022. In Europe, the alfapump is CE-marked for the management of refractory ascites due to liver cirrhosis and malignant ascites and is included in key clinical practice guidelines. Over 900 alfapump systems have been implanted to date.

Sequana Medical has combined its proven alfapump and proprietary DSR therapy, and is developing the alfapump DSR, a breakthrough approach to fluid overload due to heart failure. RED DESERT demonstrated that repeated DSR therapy in diuretic-resistant heart failure patients is able to not only manage the fluid and sodium balance of these patients but also restore their diuretic response and improve their cardio-renal status. The SAHARA DESERT study of alfapump DSR in decompensated heart failure patients is ongoing.

DANVERS, Mass.–(BUSINESS WIRE)–Abiomed (NASDAQ: ABMD) announces the successful results of the first-in-human early feasibility study of the preCARDIA system. The preCARDIA system is designed to improve decongestion in acutely decompensated heart failure (ADHF) patients by intermittently occluding the superior vena cava. The results of the study published this week in the journal Circulation: Heart Failure.

“The study met the safety and feasibility endpoints and suggests for the first time that with the preCARDIA system it is possible to rapidly reduce cardiac filling pressures and augment urine output by intermittently occluding the superior vena cava in patients with ADHF”

Despite available pharmaceutical treatments, heart failure is the leading cause of hospitalization in patients older than 65 years of age. Diuretics may help to improve heart failure symptoms and heart function by reducing fluid overload. However, diuretics take time to work and may be ineffective in patients with chronic heart failure. preCARDIA is designed to reduce filling pressure as blood enters the heart and lungs, which may enable the heart and kidneys to work more effectively, potentially providing therapy for patients non-responsive to diuretics, estimated to be approximately 300,000 of the one million U.S. ADHF admissions per year.

The multicenter, prospective, single-arm VENUS-HF Early Feasibility Study examined 30 patients with ADHF who were assigned preCARDIA therapy for 12 or 24 hours. The primary endpoint was a composite of major adverse events through 30 days. The study found:

  • Freedom from device- or procedure-related major adverse events in 100% of patients (n=30/30)
  • Successful placement, activation and removal of preCARDIA in 97% of patients (n=29/30)
  • Right atrial pressure decreased 34% from baseline (p<0.001)
  • Pulmonary capillary wedge pressure decreased 27% from baseline (p<0.001)
  • Urine output increased by 130% from pretreatment values (p<0.01)
  • Net fluid output increased by 156% from pretreatment values (p<0.01)

“The study met the safety and feasibility endpoints and suggests for the first time that with the preCARDIA system it is possible to rapidly reduce cardiac filling pressures and augment urine output by intermittently occluding the superior vena cava in patients with ADHF,” said Navin Kapur, MD, the study’s lead author and executive director of the CardioVascular Center for Research and Innovation at Tufts Medical Center.

The results support additional study of preCARDIA. In November, the United States Food and Drug Administration (FDA) authorized preCARDIA’s early feasibility study to be expanded by 30 additional patients to a total of 60 patients.

preCARDIA is an investigational device, limited by federal law to investigational use only.

InterVene’s BlueLeaf Endovenous Valve Formation (EVF) System Granted Breakthrough Device Designation by the FDA

InterVene’s BlueLeaf Endovenous Valve Formation (EVF) System Granted Breakthrough Device Designation by the FDA

Below, we are re-publishing with permission the press-release issued by InterVene, Inc. on December 13, 2021

December 13, 2021 07:00 AM Eastern Standard Time

SOUTH SAN FRANCISCO, Calif.–(BUSINESS WIRE)–InterVene Inc. announced today that it has received Breakthrough Device Designation by the FDA for the company’s BlueLeaf® Endovenous Valve Formation System. BlueLeaf is the first catheter-based solution developed for deep vein reflux — the failure of venous valves in the legs — which does not require an implant. Clinical research is underway in three separate study programs worldwide, including an Early Feasibility Study (EFS) in the US.

The Breakthrough Device Designation is granted when a device meets several criteria, including providing more effective treatment or diagnosis of life-threatening or irreversibly debilitating human disease or conditions.

The BlueLeaf System is designed to correct one of the underlying causes of chronic venous insufficiency (CVI), Deep Vein Reflux (DVR), by forming new, autologous vein valves out of the patient’s vein wall tissue via an endovascular, ultrasound image-guided approach. To date, over 25 patients with varied anatomy, disease severity, and etiology have had new vein valves formed by US and international investigators using the BlueLeaf System. Both monocuspids and bicuspid valves have been formed.

“This is a meaningful milestone for the company which offers the potential for a more timely clinical research and regulatory process for BlueLeaf. Given the debilitating nature of DVR and the lack of an effective treatment option for these patients, we’re pleased with the FDA’s decision and look forward to productive collaboration with the agency. In addition, potential economic and reimbursement benefits remain an ongoing process which we’ll follow closely as we plan and develop the next phase of our clinical research,” noted InterVene CEO Jeff Elkins.

Approximately 6.5M Americans suffer from DVR and moderate to severe CVI, a disease characterized by elevated pressure in the leg veins. DVR involves the failure of venous valves in the legs, notably in those whose valves are damaged by post-thrombotic syndrome (PTS) after iliofemoral deep vein thrombosis (DVT), leading to poor blood flow back to the heart and pooling of blood in the legs. DVR patients tend to progress to the most severe symptoms, including skin breakdown and chronic ulcers, negatively impacting their quality of lifeThe current standard of palliative treatment involves compression therapy, leg elevation and local wound care yet does not address the underlying problem of deep vein valve failure.

“The FDA’s Designation of the BlueLeaf EVF System as Breakthrough is an important recognition of both the tremendous unmet need for Deep Vein Reflux patients and the potential of the novel non-implant valve technology as treatment for the severe symptoms they frequently experience. Solutions to DVR have been elusive despite decades of research, and InterVene’s autologous, endovenous approach is worthy of prioritization, so the designation is a fitting and positive development,” said William Marston, M.D., the George Johnson Jr. Distinguished Professor of Vascular Surgery at the University of North Carolina School of Medicine.

AtriAN Medical’s Clinical Data Highlighted at the 2022 AF Symposium

Pioneering cardiac autonomic pulsed field ablation (PFA) technology provides a unique option for enhancing the durability of AF ablation.

GALWAY, Ireland, Jan. 17, 2022 /PRNewswire/ — Irish medical device company AtriAN Medical today announced that clinical data from it’s first-in-human study was presented at this years renowned Annual AF Symposium in New York City.

AtriAN has to-date enrolled nineteen patients in the company’s Neural AF multi-center study, using a unique cardiac autonomic ablation technology for the treatment of atrial fibrillation. The Neural AF study is assessing the safety and feasibility of AtriAN’s pulsed field ablation (PFA) technology for the selective ablation of cardiac autonomic neuronal tissue. An update on the clinical data was presented by Prof Vivek Reddy MD of Mount Sinai Hospital (NY), at the session on Late Breaking Clinical Trials and First Report Investigations, on January 14th, 2022.

The treatment methodology targets specific locations on the exterior surface of the heart where atrial fibrillation initiates. By delivering very short and precise electric fields, the device eliminates hyperactive neuronal cells at these locations. This leads to a reduction in the heart’s overall sensitivity to atrial fibrillation. 

The first procedures have been performed on patients undergoing concomitant coronary artery bypass grafting (CABG); at Tbilisi Heart & Vascular Clinic in Georgia and Na Homolce Hospital, in Prague, Czech Republic. “The AtriAN system is an exciting development, opening up the possibility of addressing the autonomic origin of atrial fibrillation, which has largely been ignored by existing ablation technologies,” said Prof Tamaz Shaburishvili of Tbilisi Heart & Vascular Clinic.

The AtriAN system includes catheters designed for use within the pericardial space and a generator for providing the low energy pulsed electric fields, that are delivered via the catheters, directly into the epicardial neuronal tissues. 

“The field of selective cardioneuroablation offers great promise among the treatment options for atrial fibrillation and it is exciting to see the AtriAN system now being assessed clinically,” said Prof Joris de Groot, at Amsterdam UMC. “Arrhythmia recurrence is a widespread problem with current ablation technologies – the AtriAN selective autonomic ablation has the potential to resolve this issue.”

“The positive outcomes from these initial patients is a key clinical milestone for us, following on from several years of scientific research and engineering development,” said AtriAN CEO Ken Coffey. “We look forward to continuing development of the technology in order to bring it to wider cohorts of patients.”
