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.
