Patient Enrollment Begins in Everolimus Drug-Coated Balloon Study

Below, we are re-publishing with permission the press-release issued by Cardiovascular Systems Inc. on September 02, 2022

Cardiovascular Systems has an acquisition option agreement with the balloon’s developer, Chansu Vascular Technologies.

Cardiovascular Systems Inc. (CSI) has begun enrolling patients in its coronary everolimus drug-coated balloon study.

The first patient was treated by Dr. Iraki Gogorishvili, head of the Interventional Cardiology Department at the Israeli-Georgian Medical Research Clinic Helsicore in Tbilisi, Georgia. “The crossability and deliverability of the CVT DCB is excellent and I am very excited to participate in this research project evaluating this new class of DCBs,” Gogorishvili said. 

The coronary DCB was used to treat in-stent restenosis (ISR) located in the left anterior descending artery. The balloon involved in this first-in-human trial was developed by Chansu Vascular Technologies LLC (CVT). CSI is providing milestone-based financing to CVT for the development of coronary and peripheral DCBs. Under an acquisition option agreement, CSI has exclusive rights to acquire CVT upon completion of certain technical and clinical milestones in the development program.

DCBs are a widely accepted percutaneous interventional treatment option for femoro-popliteal lesions in patients with peripheral artery disease, and are increasingly recognized for their potential in complex coronary artery disease, ISR, small vessels, and bifurcation lesions. Everolimus, the active drug in CVT’s DCB formulation, acts as a cytostatic agent to reduce tissue hyperplasia and associated restenosis and has a long history of safety and efficacy in coronary drug-eluting stent applications. 

“The CVT DCBs are designed to capitalize on the proven long-standing anti-restenotic benefits of everolimus for the treatment of patients with cardiovascular lesions. CVT intends to enroll 50 patients at up to 15 sites in France, Georgia, Lithuania, and Spain to support an IDE submission to the FDA and a subsequent U.S. pivotal clinical study,” said Ryan Egeland, M.D., Ph.D., CSI’s chief medical officer. 

CAD is a life-threatening condition and a leading cause of death in men and women globally. CAD occurs when a fatty material called plaque builds up on the walls of arteries that supply blood to the heart. The plaque buildup causes the arteries to harden and narrow (atherosclerosis), reducing blood flow. The risk of CAD increases if a person has one or more of the following: high blood pressure, abnormal cholesterol levels, diabetes, or family history of early heart disease. According to the Centers for Disease Control and Prevention, 18.2 million people in the United States have CAD, the most common form of heart disease. Heart disease claims more than 650,000 lives in the United States each year. According to estimates, significant arterial calcium is present in about 30 percent of patients undergoing a PCI. Significant calcium contributes to poor stent delivery, expansion and wall apposition leading to poor outcomes and higher treatment costs in coronary interventions when traditional therapies are used, including a significantly higher occurrence of death and major adverse cardiac events (MACE).

Based in St. Paul, Minn., CSI develops and commercializes solutions for treating vascular and coronary disease. The company’s orbital atherectomy system treats calcified and fibrotic plaque in arterial vessels throughout the leg and heart and addresses many of the limitations associated with existing surgical, catheter and pharmacological treatment alternatives. 

Chansu Vascular Technologies is located in Sunnyvale, Calif. CVT was founded by Philippe Marco, M.D., to develop peripheral and coronary DCBs using everolimus. Marco is a 25-year medical technology veteran who has spent his entire career focused on cardiovascular device development. He was president and chief operating officer (COO) of Epix Therapeutics (acquired by Medtronic), and president and COO at CV Ingenuity (acquired by Covidien), where he was responsible for the development of the Stellarex DCB. Marco started working on drug delivery cardiovascular devices while in charge of Medical Affairs for Abbott Vascular where, following the Perclose Inc. acquisition, he led the franchise expansion into a diversified portfolio from closure devices to drug-coated coronary stents, embolic protection devices, and peripheral catheters and stents.

Newly Published Chronic Heart Failure Treatment Study Provides Promising Results for EVBA Procedure with Unique MobiusHD Device

Below, we are re-publishing with permission the press-release issued by Vascular Dynamics, Inc. on October 18, 2022

Vascular Dynamics, Inc. (VDI), a privately held medical device company focused on developing game-changing endovascular device-based solutions for patients suffering from heart failure, announced that a study assessing its MobiusHD device to treat patients with chronic heart failure has been published in the peer-reviewed journal, Structural Heart.

The findings and clinical meaningfulness assessments are reported by interventional and cardiovascular surgeons in the article, “Endovascular Baroreflex Amplification With the MobiusHD Device in Patients With Heart Failure and Reduced Ejection Fraction: Interim Analysis of the First-in-Human Results.”

The authors conclude that the MobiusHD device implantation in progressive heart failure patients, who had previously remained highly symptomatic despite guideline-directed medical therapy, was safe and resulted in clinically meaningful improvements in health status, functional exercise capacity, NT-proBNP levels, and left ventricular ejection fraction (LVEF) changes that emerged within three months after device implantation and were sustained through 12 months follow-up in the feasibility clinical trial.

“The clinical results of this feasibility study have shown impressive efficacy,” said JoAnn Lindenfeld, MD, a heart failure specialist at Vanderbilt University Medical Center, and one of the study’s co-authors. “That all patients underwent successful and uneventful device implantation and experienced positive changes in quality of life and exercise capacity is encouraging, and we look forward to learning more in the forthcoming pivotal study further examining this promising technology.”

The endovascular baroreflex amplification (EVBA) procedure enables placement of the MobiusHD implant in the targeted site within the carotid sinus. After identifying the preferred target location using pre-procedure imaging, the procedure is typically completed in less than 30 minutes.

The unique MobiusHD device mechanically stimulates the arterial baroreceptor reflex by changing the geometric shape of the carotid sinus to increase local arterial wall stretch while preserving pulsatility. The resulting amplified nerve signaling triggers decreasing sympathetic activity and increasing parasympathetic activity. This rebalancing of the autonomic nervous system is believed to improve symptoms and prevent progression of HFrEF. In this way, the MobiusHD offers a potential device-based solution for symptomatic heart failure patients who are not responding to drug treatment.

“The results from this published study further validate and add to the evidence supporting the potential value of the MobiusHD technology, as a potential game-changer for chronic heart failure sufferers who have not responded well to traditional treatments, despite being well-medicated” commented Ed Roschak, CEO of Vascular Dynamics. “We look forward to advancing our evaluations in this ongoing study including patients from Canada, Australia, and Germany. Also, a pivotal clinical trial is planned and will include a sham-controlled, randomized study protocol.”

Miracor Medical Announces FDA IDE Approval For PiCSO® Pivotal Study

Below, we are re-publishing with permission the press-release issued by Miracor Medical on August 23, 2022

AWANS, Belgium–(BUSINESS WIRE)–Miracor Medical SA (Miracor Medical) has announced the approval of an Investigational Device Exemption (IDE) from the FDA, enabling the company to initiate a pivotal study with its Pressure-controlled intermittent Coronary Sinus Occlusion (PiCSO) technology. The PiCSO-AMI-II multicenter, randomized trial will enroll 300 patients with anterior ST-segment Elevation Myocardial Infarction (STEMI) presenting with TIMI flow 0, 1, and 2 within 12 hours of symptom onset. The primary efficacy endpoint of the study will be infarct size measured by cardiac magnetic resonance imaging (CMR) at 5 days. The primary safety endpoint is a performance goal for device and procedure related adverse events at 30 days. Major adverse cardiac events and heart failure endpoints will be captured acutely and for up to 3 years.

PiCSO-AMI-II will be the second major randomized trial to evaluate the role of PiCSO in improving coronary microvascular function and reducing infarct size in patients presenting with anterior STEMI. Miracor is currently recruiting 144 patients in PiCSO-AMI-I, a landmark European randomized controlled trial, with comparable endpoints as the approved US trial. Recruitment in the European study is expected to end this summer. It is anticipated that a future patient-level pooled meta-analysis of the two studies will demonstrate a hard clinical endpoint improvement in heart failure hospitalization.

PiCSO is used as an adjunctive procedure after epicardial flow has been restored during the primary percutaneous coronary intervention (PCI) procedure. The unique mechanism of action, of intermittently occluding the coronary sinus outflow, redistributes venous blood-flow to the peri-infarct zone and enhances the coronary microcirculation viability by washing-out debris and other noxious agents of the infarct process. Early non-randomized European studies have suggested that this leads to reduced incidence of coronary microvascular obstruction (MVO) [3,4] and smaller infarct size, which are both strongly correlated to improvement in heart failure hospitalizations and reduced mortality following primary PCI [5]. Despite improvements in patient care pathways, widespread use of reperfusion strategies, and adjuvant pharmacological therapies, the one-year mortality rate after STEMI in high-risk patients has plateaued over the past decade at 14% [1]. Also, heart failure development after hospital discharge is very prevalent, being diagnosed in approximately 13% of patients at 30 days and 20–30% at 1 year after discharge [2].

“Reducing infarct size and MVO is a key factor in improving survival and reducing the risk of heart failure among patients with heart attack. PiCSO therapy is a promising new therapy to reduce infarct size and improve outcomes in anterior STEMI patients. The FDA-approved randomized IDE trial has been designed to validate the safety and effectiveness of PiCSO.” said Prof. Gregg W. Stone, (Director of Academic Affairs for the Mount Sinai Heart Health System, New York, NY, USA) who will be study principal investigator, with Prof. Marco Valgimigli of Istituto Cardiocentro Ticino in Lugano, Switzerland, as the study co-principal investigator.

“In addition to the ICD-10-PCS code that was granted by the Centers for Medicare and Medicaid Services (CMS) in April 2022, the Investigational Device Exemption marks a key milestone in the company’s lifecycle and speaks to the positive evolution of the company. We look forward to conducting a meticulous study with our clinical investigators to bring PiCSO to American patients.” said Olivier Delporte, CEO. The company plans to raise funds later this year to execute this important study, support company operations and assess potential partnerships for Asia.

The PiCSO Impulse System received ‘Breakthrough Designation’ from the FDA in 2019 and the CE-Mark in 2020. The development of Miracor’s PiCSO technology is supported by a reimbursable cash advance from the Walloon Region since August 2017.

Sequana Medical announces positive top-line results from SAHARA Ph. 2a study of DSR 1.0 in diuretic-resistant heart failure patients with persistent congestion and first patient dosed successfully with DSR 2.0 in YUKON

Below, we are re-publishing with permission the press-release issued by Sequana Medical on November 15, 2022

15 November 2022, 07:00 am CET

  • Data from SAHARA with first-generation DSR product (DSR 1.0) confirm:
    • Safe, effective and rapid elimination of persistent congestion following intensive DSR therapy
    • Considerable benefit in cardio-renal status maintained till end of study (16 weeks post-intensive DSR therapy)
    • Dramatic and sustained improvement in diuretic response up to 15 months post intensive DSR therapy
    • No congestion-related heart failure re-hospitalizations during entire study
    • One class improvement of NYHA status and 75% reduction in predicted one-year mortality based on Seattle Heart Failure model
  • First patient dosed successfully in YUKON, Ph. 1 study of second-generation DSR product (DSR 2.0)
  • MOJAVE, US Ph. 1/2a randomized controlled multi-center study of DSR 2.0, on track to start in H1 2023
  • Company presentation with webcast at Jefferies Healthcare Conference on 17 November 2022

Ghent, Belgium – 15 November 2022 – Sequana Medical NV (Euronext Brussels: SEQUA) (the “Company” or “Sequana Medical“), a pioneer in the treatment of drug-resistant fluid overload in liver disease, heart failure and cancer, today announces positive top-line results from SAHARA, the Phase 2a study using its first-generation DSR (Direct Sodium Removal) product (DSR 1.0). Data from ten[i] evaluable diuretic-resistant heart failure patients with persistent congestion who have completed the 16-week follow-up period after intensive DSR therapy confirm the previously reported strong interim data[ii] showing important and long-lasting clinical benefits.

To evaluate the safety, tolerability and efficacy of the Company’s second-generation DSR product (DSR 2.0), a single-arm, open-label, Phase 1 study has been initiated in Canada (YUKON) with up to 10 patients on peritoneal dialysis receiving a single treatment of DSR 2.0. The first patient has been dosed successfully and the results of this study will be used to determine dosing of DSR 2.0 in MOJAVE. Data from YUKON, together with CHIHUAHUA, a further Phase 1 study in Mexico intended to support the US IND[iii] filing of DSR 2.0, planned for Q1 2023. These replace the previously planned SAHARA extension study with DSR 2.0. Approval of the US IND will enable the Company to start MOJAVE, its randomized controlled multi-center Phase 1/2a US study of DSR 2.0, planned for H1 2023.

Dr. Jeffrey Testani, Associate Professor at Yale University and Heart Failure Scientific Advisor to Sequana Medical, commented“Congestion is a key driver of heart failure and remains the leading cause of morbidity and hospitalization in this large and growing patient population. Diuretic-resistance is widespread and the usual therapeutic approach is just adding more diuretics, further worsening the underlying issues. There are no therapies that seek to correct the cardio-renal pathophysiology causing the diuretic-resistance. The SAHARA results are highly encouraging and indicate the potential for DSR therapy to deliver clinically meaningful decongestion and durable improvements in cardio-renal function and thus diuretic response.”

Dr. Oliver Gödje, Chief Medical Officer of Sequana Medical, added: “These results are very positive and reinforce our view that DSR is a potential disease-modifying heart failure therapy. We are excited to have the first patient dosed with DSR 2.0 and we are confident that this second-generation product will deliver important therapeutic and safety benefits. I would like to thank the investigators, patients and care personnel involved in both SAHARA and YUKON, and we look forward to commencing MOJAVE, the first randomized controlled multi-center study in the US using DSR 2.0.”

SAHARA top-line results

At baseline, all teni evaluable patients with persistent congestion due to heart failure were on high dose loop diuretics (mean furosemide equivalent dose of 360 mg/day) and had an overall high disease severity, including a mean left ventricular ejection fraction of 23% and mean NT-proBNP of 6,628 pg/mL. At the start of the study treatment period, loop diuretics were withheld, and patients underwent intensive DSR therapy with DSR 1.0 for two weeks (phase 1) which was repeated up to two times depending on patients’ euvolemic state (i.e., normal amount of body fluids), diuretic response and stable DSR dosing at the end of phase 1. Patients who achieved euvolemia and had adequate diuretic response entered the maintenance DSR treatment phase with monthly DSR dosing for 16 weeks (phase 2).

All ten evaluable patients safely, effectively and rapidly eliminated the persistent congestion and achieved euvolemia within one week of commencing intensive DSR therapy, resulting in a mean weight loss of 7kg at the end of phase 1. During the intensive DSR period (phase 1), the diuretic response of the kidney was near-normalised, with mean six-hour excretion of sodium increasing more than 160% vs. baseline, as well as a considerable improvement in cardio-renal health, with a mean reduction in NT-proBNP[iv] of 38% vs. baseline and a mean improvement in eGFR[v] of 7% vs. baseline despite the dramatic fluid loss.

The improvement in cardio-renal health was broadly maintained at the end of phase 2 (16 weeks post intensive DSR period) demonstrated by a mean 33% reduction in NT-proBNP and a stable eGFR.

The need for loop diuretics was dramatically reduced for many months following completion of the intensive DSR therapy (see table below), which the Company believes is a demonstration of the durable improvement in cardio-renal health.

Evaluable patientNo. of months post intensive DSR periodReduction in diuretic dose vs. baseline

No clinically relevant changes in serum sodium levels or progressive hyponatremia were observed in any of the evaluable patients. There were three serious adverse events in three of the evaluable patients, including two having a blocked peritoneal catheter (both during phase 2) and one with stable angina (started post phase 2, ongoing). The Data Monitoring Committee assessed both peritoneal catheter blockages as definitely related to the study device but unrelated to the implant procedure or study treatment, and the stable agina as unrelated to the study device, implant procedure, or treatment.

All evaluable patients treated with DSR therapy in the RED DESERT and SAHARA clinical studies experienced no congestion-related heart failure hospital re-admissions during the entire study period and all patients improved their NYHA[vi] status by at least one class. The clinical benefits observed in RED DESERT and SAHARA resulted in a 75% reduction in predicted one-year mortality of patients pre- vs. post-intensive DSR therapy based on the Seattle Heart Failure Model[vii].

On track to start MOJAVE with DSR 2.0 in H1 2023

The Company is progressing development of its proprietary DSR 2.0 product, a sodium-free dextrose / icodextrin solution expected to have an improved therapeutic and favourable safety profile and with a robust intellectual property protection. Data from two interventional, single-centre, single-arm studies, one in Canada (YUKON) and one in Mexico (CHIHUAHUA) will evaluate the safety, tolerability and efficacy of DSR 2.0. Both studies will enroll up to ten stable peritoneal dialysis patients who will receive a single treatment of DSR 2.0, administered through their peritoneal dialysis catheter. The first patient has been treated successfully in YUKON and data from both studies intended to support the filing of the US IND, planned for Q1 2023. The choice of peritoneal dialysis patients is driven by their pre-existing peritoneal dialysis catheter.

Following initial discussions with the FDA, MOJAVE, a randomized controlled Phase 1/2a US study of DSR 2.0, is on track to start in H1 2023 assuming FDA approval of the US IND.  The intention is to enrol 30 diuretic-resistant chronic heart failure patients with persistent congestion, with 20 patients randomised to DSR 2.0 administered via a peritoneal catheter on top of usual care for congestive heart failure (CHF) for up to four weeks and ten patients randomised to usual care for CHF alone. Following four weeks of DSR therapy there will be a three-month safety follow-up period. Prior to enrolment of these 30 patients, three additional patients will be enrolled in a non-randomized safety cohort and will receive DSR 2.0 administered via a peritoneal catheter on top of usual care for CHF for up to four weeks. Progression to the enrolment of the 30 randomized patients will be dependent upon DSMB[viii] approval following their review of the initial three patients. More details on the final study design will be announced following FDA approval of the US IND. Interim data of MOJAVE are planned for H2 2023 and top-line results are expected in mid 2024.

About fluid overload in heart failure (AKA congestion)

Heart failure is the leading cause of US hospitalizations in patients over 65 years old and 90% of these admissions are due to fluid overload, which is recognized as the primary driver of morbidity and hospitalization. Standard of care includes treatment with diuretic drugs, but these have well recognized toxicity and resistance issues. Half of the heart failure patients admitted for fluid overload are discharged with no clinically relevant loss of fluid and one in four is re-admitted to the hospital within 30 days of discharge. It is estimated that 200,000 US heart failure patients have drug-resistant congestion requiring repeated hospitalization, severely impacting their survival and quality of life and creating a heavy financial burden.

About DSR® (Direct Sodium Removal) in heart failure

Sequana Medical considers its proprietary DSR to be a disease modifying therapy for heart failure. Fluid accumulation in heart failure patients is caused by the retention of too much sodium. The DSR drug-based approach directly tackles this key clinical problem of sodium overload, and works in partnership with the kidneys to safely and rapidly eliminate the excess fluid. Complementary to existing heart failure therapies, clinical proof-of-concept studies using the Company’s first-generation DSR product (DSR 1.0) have shown that DSR can i) safely, effectively and rapidly eliminate fluid overload in heart failure patients, ii) improve the health of the heart and preserve renal function, and iii) restore the ability of the kidney to manage the fluid and sodium naturally, resulting in a large and long-lasting reduction in the need for diuretic drugs. In DSR treated patients, there have been no congestion-related re-hospitalizations during the study follow-up period, all patients improved their NYHA status by at least one class and the clinical benefits observed in the clinical studies resulted in a 75% reduction in predicted one-year mortality of patients pre- vs. post-intensive DSR therapy based on the Seattle Heart Failure Model. The Company is currently preparing an IND application for its second-generation DSR product (DSR 2.0) in the US and plans to begin a US randomized controlled Phase 1/2a clinical trial in H1 2023. Composition of matter and method patents have been granted for DSR therapy in the US and Europe.

Maxwell Biomedical Completes First-in-Human Study Enrollment and Testing of Spatial Resynchronization™ Therapy

Successful Spatial Resynchronization™ Therapy (SRT) conversion of AFib to normal rhythm

Below, we are re-publishing with permission the press-release issued by Maxwell Biomedical on October 20, 2022

Spatial Resynchronization Therapy (SR™T) demonstrates proof-of-concept in repeatedly terminating atrial fibrillation (AFib) and restoring sinus rhythm

SAN DIEGO, CALIFORNIA, UNITED STATES, October 20, 2022 / — Maxwell Biomedical announced today that it has successfully completed enrollment in its First-in-Human Clinical Trial “Initial Experience with Spatial Resynchronization Therapy in Patients with Atrial Fibrillation (NCT 05461612)” being conducted at the Tbilisi Heart and Vascular Clinic in Tbilisi, Georgia. SRT is a device-based approach that features a proprietary algorithm for diagnosing and treating AFib. The graphic is one of several successful conversions of AFib to normal rhythm demonstrated during the recent study.

The idea of imperceptible stimulation to gain control of the arrhythmia and restore sinus rhythm in AFib patients is not new. The methodology, timing, and location of stimulus delivery represent the unique aspects of the Maxwell System. Once AFib is detected, instead of delivering pacing to a single site, SRT determines where to deliver stimuli across a spatially distributed network of electrodes placed on the epicardial surface of the left atrium. Pacing stimuli are precisely timed to be delivered within the excitable gap, allowing the system to capture and control the atrial tissue and restore the normal rhythm.

“We are extremely encouraged by the results from this most recent study,” stated Randy Werneth, CEO of Maxwell Biomedical, “These latest results will further advance our System and SRT algorithm bringing us closer to delivering a device-based treatment for patients with all types of AFib.”

Atrial Fibrillation

Atrial fibrillation is the most common heart arrhythmia affecting over 33 million patients worldwide.1 It occurs when the upper chambers beat uncontrollably and are out of synchronization with the lower chambers of the heart. The lack of coordinated contractions during prolonged episodes of AFib increases the likelihood of blood clot formation and reduces the amount of blood available to pump to the body. AFib increases stroke risk five times2 increases mortality rates two-fold in heart failure patients3 and costs the United States healthcare system $26B annually1. Current AFib treatment options include outpatient cardioversion, rate or rhythm control medications, and catheter ablation. SRT would offer patients a non-destructive, minimally invasive option to treat their AFib.

About Maxwell Biomedical

We are a development-stage, science-driven, innovative medical technology company with outstanding people dedicated to advancing long-term solutions for patients with Atrial Fibrillation. Maxwell is developing a first-of-its-kind atrial pacing device that automatically detects AFib and imperceptibly delivers SRT to restore and maintain a normal heart rhythm. Device monitoring and cloud connectivity ensure active and continuous patient care and management. Founded in 2019, Maxwell Biomedical is based in San Diego, CA.

May 26, 2022 — 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.”

Maxwell Biomedical Receives NIH Small Business Innovation Research Grant

Below, we are re-publishing with permission the press-release issued by Maxwell Biomedical on September 15, 2022

Grant money will be used to support the research and development of Spatial Resynchronization™ Therapy (SR™T) to treat atrial fibrillation (AFib)

SAN DIEGO, Calif., September 15 2022 Maxwell Biomedical announced today that is has been awarded a Phase I Small Business Innovation Research (SBIR) grant from the National Heart Lung and Blood Institute (NIH) to pursue development and testing of their proprietary SRT device designed specifically to diagnose and treat AFib. Phase I SBIR grants are awarded to small businesses to establish the technical merit, feasibility, and commercial potential of the proposed product.

SRT is a significant advancement of science that was published in 1997, in which single-site stimulation was able to locally capture tissue at specific locations in human right atria during spontaneous AFib.1 Once AFib is detected, instead of delivering pacing to a single site, SRT delivers pacing stimuli across spatially distributed electrodes placed on the epicardial surface of the left atrium. Pacing stimuli, which are imperceptible to the patient, are delivered within the excitable gap to capture and control atrial tissue for restoration of normal rhythm.

“Atrial fibrillation is debilitating and contributes to worsening health in patients with co-morbidities,” stated Randy Werneth, CEO of Maxwell Biomedical, “We are pleased that the NIH and it’s review committee have recognized the unique aspects and potential of our technology to provide a nondestructive treatment for patients with all types of AFib.”

Atrial Fibrillation

Atrial fibrillation is the most common heart arrhythmia affecting over 33 million patients worldwide.2 It occurs when the upper chambers beat uncontrollably and are out of synchronization with the lower chambers of the heart. The lack of coordinated contractions during prolonged episodes of AFib increases the likelihood of blood clot formation and reduces the amount of blood available to pump to the body. AFib increases stroke risk five times3, increases mortality rates two-fold in heart failure patients4 and costs the United States healthcare system $26B annually2. Current AFib treatment options include outpatient cardioversion, rate or rhythm control medications and catheter ablation. SRT would offer patients a non-destructive, minimally invasive option to treat their AFib.

About Maxwell Biomedical

We are a development stage, science driven, innovative medical technology company with outstanding people dedicated to advancing long-term solutions for patients with Atrial Fibrillation. Maxwell is developing a first-of-its-kind atrial pacing device that automatically detects AFib and imperceptibly delivers SRT to restore and maintain a normal heart rhythm. Device monitoring and cloud connectivity ensures active and continuous patient care and management. Founded in 2019, Maxwell Biomedical is based in San Diego, CA.

AtriAN Medical Completes Enrollment of Second Study on Cardioneuroablation using PFA

Below, we are re-publishing with permission the press-release issued by AtriAN Medical on September 06, 2022

This follow-up trial builds on AtriAN’s initial safety and feasibility study and aims to assess the efficacy of its cardioneuroablation treatment in patients with atrial fibrillation. 

GALWAY, Ireland, Sept. 6, 2022 /PRNewswire/ — AtriAN Medical today announced that it has completed enrollment of a second study using its selective pulsed field ablation (PFA) technology for the treatment of atrial fibrillation.

The Neural AF-2 study has enrolled cardiothoracic surgery patients with paroxysmal AF, utilizing AtriAN’s unique cardiac autonomic ablation technology to provide selective ablation of neuronal structures on the outside of the heart. A total of 12 patients were treated at Tbilisi Heart and Vascular Clinic (Georgia), with Prof Tamaz Shaburishvili as the Principal Investigator. Patients will be followed out to 1 year for AF recurrence.

The new study builds on AtriAN’s initial Neural-AF study that focused on safety, feasibility and acute outcomes, in twenty four patients undergoing concomitant coronary artery bypass grafting. The initial study was performed at Na Homolce Hospital in Prague (Czech Republic) and Tbilisi Heart and Vascular Clinic (Georgia). Data from that study was presented by Prof Vivek Reddy MD (Mount Sinai Hospital, NY) at the 2022 AF Symposium and by Prof Joris de Groot (Amsterdam UMC) at the European Heart Rhythm Association (EHRA) 2022 conference. 

The original Neural-AF study was an all-comers design for CABG patients that did not focus specifically on patients with atrial fibrillation. The findings indicate that selective epicardial PFA of ganglionated plexi is feasible and safe.  An acute extension in atrial tissue refractoriness was also recorded; this is a well recognized indicator of resistance to atrial fibrillation.

 “The promising results from our first study have given us the confidence and momentum to expand into this second trial looking specifically at clinical outcomes in patients with AF” said AtriAN CEO Ken Coffey. “This will be a challenging cohort of patients but we look forward to providing them with improved outcomes and demonstrating the potential of our novel approach.”

The AtriAN system includes catheters designed for use within the pericardial space and a generator for providing low energy pulsed electric fields. In the near future, the company plans to conduct clinical studies to assess delivery of the treatment using sub-xiphoid minimally invasive access.
