Maxwell Biomedical Initiates First-in-Human Trial to Assess the Safety and Efficacy of а Novel Pacing Intervention in Patients with Atrial Fibrillation

Spatial Resynchronization Therapy™ (SR ™Т) Successfully Terminated Atrial Fibrillation

Below, we are re-publishing with permission the press-release issued by Maxwell Biomedical on July 14, 2022

SAN DIEGO, Calif., July 14, 2022. Maxwell Biomedical announced today that it has initiated its First-ln­ Human Clinical Trial “Initial Experience with Spatial Resynchronization Therapy in Patients with Atrial Fibrillation (SR-TheAF)” at the Tbilisi Heart and Vascular Clinic in Tbilisi, Georgia. The study is designed to test the acute safety and efficacy of Spatial Resynchronization™ Therapy (SR™T) in patients with а history of atrial fibrillation (AF). The study will enroll up to 30 patients. During the initial studies, AF was successfully detected and termination with SRT pacing was demonstrated.

Spatial Resynchronization Therapy (SRT) is а Maxwell’s proprietary algorithm designed specifically to treat AF. Once AF is detected, SRT delivers pacing stimuli across а spatially distributed array of electrodes placed on the pericardial wall of the left atrium. Pacing stimuli, which are imperceptible to the patient, are precisely delivered to restore normal rhythm.

“We are very excited about the acute performance of SRT in this first series of patients,” stated Randy Werneth, СЕО of Maxwell Biomedical, “This represents а major milestone in our development pathway to bring а device-based treatment option to patients with AF.” Working alongside the surgical team in Tbilisi was Mehdi Razavi, MD, an entrepreneurial electrophysiologist from the Texas Heart Institute in Houston Texas, who has been working closely with the Maxwell Biomedical team to develop and pre­ clinically test the SRT concept. “In the past, pacing was tried with limited success to convert AF to а normal rhythm,” said Dr. Razavi, “SRT is а new methodology, based on insights gained from past experiences and rooted in the underlying biophysics of human fibrillatory conduction.”

AF is the most common heart arrhythmia affecting over ЗЗ 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 AF increases the likelihood of blood clot formation and reduces the amount of blood available to pump to the body. AF increases stroke risk five times2, increases mortality rates two-fold in heart failure patients3 and costs the United States healthcare system $26В annually1. Current AF treatment options include outpatient cardioversion, rate or rhythm control medications and catheter ablation. SRT would offer patients а non-destructive, minimally invasive option to treat  their AF.

About Maxwell Biomedical

We are а 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 а first of its kind, non-ablative, atrial pacing device that automatically detects AF and imperceptibly delivers Spatial Resynchronization Therapy (SRT) to restore and maintain а 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, СА.

BetaGlue announces the treatment of the first patient with BAT-90, taking radiotherapy inside solid tumours

Below, we are re-publishing with permission the press-release issued by BetaGlue Technologies on July 11, 2022

BetaGlue Technologies, a highly innovative company working in the Life Sciences sector, is glad to announce that the first patient has been treated in a clinical trial with BAT-90, the company’s cancer radiotherapy platform. The first clinical results have shown that BAT-90 makes it possible to treat only the area where the tumour is located, while avoiding the surrounding tissues, so as to combine treatment efficacy and patient safety.
The clinical trial in liver cancer patient has been coordinated by Professor Malkhaz Mizandari at the New Hospitals in Tbilisi (Georgia), an international centre of excellence affiliated with Thomas Jefferson University in Philadelphia (USA).
BAT-90 (‘Beta Ablation Therapy with Yttrium-90’) consists of a β radiation-emitting biocompatible matrix, delivered to patients via percutaneous injection: the Yttrium-90-labelled microspheres present inside the matrix are injected into the tumour and, as the carrier takes only 120 seconds to reach full polymerisation, they are retained exclusively in the injected area. This prevents the microspheres from spreading to surrounding tissues or organs, so as to release their radiation energy only to the target tumour. In this way, a very low radioactive dose is needed, much lower than the one used with conventional radio-metabolic treatments, thus enhancing treatment efficacy and patient safety.
BAT-90 opens up important horizons in oncology, bringing benefits to both patients and the healthcare systems. Indeed, BAT-90 is a therapeutic nuclear medicine solution that is extremely precise (it only targets the tumour area), personalised (calibrated to the patient’s clinical situation), rapid (a single injection reaching full polymerisation in just a few minutes) and safe (the radiation energy is released where needed, avoiding exposure of surrounding tissues and organs, thus minimizing any risk to either patients or healthcare professionals).

BetaGlue Technologies SpA
BetaGlue Technologies is a highly innovative company working in the Life Sciences sector.  The Company has developed BAT-90, an advanced radiotherapy platform targeting inoperable solid tumors and/or surgical resection margins. BetaGlue is also patenting a medical device that enables safe biopsies in oncology, preventing even severe complications after lung or liver procedures. BetaGlue enjoys the support of a highly qualified Scientific Advisory Board, as well as of leading national and international advisers, in the development of its solutions.

Clinical Accelerator announces collaboration with CryoTherapuetics – a medical device company focused on treating coronary artery disease

Clinical Accelerator, a full-service, medical device focused contract research organization, is pleased to announce a new partnership with CryoTherapeutics – an early-stage European medical device company which has developed a novel cryoenergy therapy for the treatment of inflamed atherosclerotic plaque, a major cause of heart attack.

Currently  there is no approved interventional treatment for this indication, but CryoTherapeutics hopes to change that with their therapy which will target areas of the coronary artery where there is inflammatory disease. The system consists of a console delivering a cryogen to the tip of a catheter which then delivers cryotherapy at below zero temperatures to the specific site in the coronary artery. The procedure is conducted with the assistance of invasive of non-invasive imaging to ensure precise placement

CryoTherapeutics’s feasibility study will be managed by Clinical Accelerator and we are thrilled to be a part of this project. We are looking forward to using our expertise in clinical trial management of FIH and early feasibility studies to result in a successful study.

Axon Therapies Announces Positive Early Clinical Data from REBALANCE-HF Randomized Clinical Trial

Axon Therapies

Below, we are re-publishing with permission the press-release issued by Axon Therapies on May 23, 2022

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.”

About Axon Therapies, Inc.
Axon Therapies, a private medtech company, is developing a minimally invasive therapy that aims to address a root cause of heart failure by restoring balance to the sympathetic nervous system.

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.

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.
