Key study findings include: Durable 15-22 month results with an average of 74% volume reduction of treated benign thyroid nodules with overwhelming patient satisfaction reported; Continued volume reduction improvements from 1 month through 22 months; No regrowth of nodules at 15-22 months; Patient-reported Cosmetic Satisfaction: 100% were Highly Satisfied at final follow-up; Patient-reported Overall Satisfaction: 95% were Highly Satisfied at final follow-up; No serious adverse events; No intranodular fibrosis detected on ultrasounds at 15-22 months; Potential for clinical durability of benign thyroid ablation. These long-term benefits manifest the uniqueness of nsPFA as differentiated from all other present forms of Pulse Field Energy Ablation, namely the speed of particle flow as well as the absolute voltage pressure per unit of time. This study is an extension of the initial feasibility study conducted at Ospedale del Mare in Naples, Italy, which evaluated nsPFA energy for the treatment of benign thyroid nodules. The study was extended to allow for long-term follow-up of a subset of the patients included in the initial study. A total of 21 patients were subsequently monitored between 15 and 22 months to evaluate volume reduction trends over time. These data on initial feasibility and clinical durability demonstrated significant progress in the development of clinical evidence for the use of nsPFA energy for the ablation of benign thyroid nodules. While the work to establish clinical outcomes of nPulse Vybrance for benign thyroid nodules is early, these data provide the first long-term results of sustained tissue responses. Evidence of sustainable volume reduction and high patient satisfaction, added to the inherent procedural safety and soft tissue response of nsPFA ablation, provide promising signals to pursue in future market development work.

Pulse Biosciences, Inc. Announces Successful Treatment of Patients in First-in-Human Study with its Nano-PFA Cardiac Surgery System Pulse Biosciences, Inc. announced treatment of the first two patients in the first-in-human feasibility study using its novel Cardiac Surgery System for the ablation of cardiac tissue for the treatment of atrial fibrillation. Dr. Bart Van Putte, Cardiothoracic Surgeon at St. Antonius Hospital, used the Company's Cardiac Surgery System to successfully treat two patients with atrial fibrillation at St. Antonius Hospital., Nieuwegein, The Netherlands. Pulse's Cardiac Surgery System with Surgical Clamp is designed to produce durable, continuous, transmural, ablation lesions during cardiac surgery procedures for the treatment of atrial Fibrillation. Also, due to the non-thermal mechanism of action of nano-PFA, there is no risk of thermal spread that may cause undesired injury to collateral tissues, which compares favorably to thermal radiofrequency ablation. The nano-PFA Cardiac Surgical System received FDA Breakthrough Device Designation in early July 2024. Recently the device was enrolled in the FDA's TAP program. The FDA's Center for Devices and Radiological Health (CDRH) launched the TAP program to help generate more rapid development of high-quality, safe, effective, and innovative medical devices that are critical to public health. TAP's primary goal is to expedite patient access to innovative medical devices by providing early, frequent and strategic communications with the FDA and facilitating engagement with other key parties for developers of devices of public health importance. According to its website, the FDA has enrolled 46 devices in the TAP program to date, while there have been over 900 Breakthrough Device Designations granted. The Company plans to pursue FDA premarket approval (PMA) to commercialize its nano-PFA CardiacSurgical System in the United States as a treatment for atrial fibrillation. If granted by the FDA, a specific treatment indication would permit direct marketing of the device's treatment benefits. The Company intends to begin its pivotal clinical study of its nano-PFA Cardac Surgical System as a treatment for atrial Fibrillation in early 2025 and will provide additional details on the study and its regulatory and commercial implications later this year.

Pulse Biosciences, Inc. Announces Receipt of FDA Breakthrough Device Designation for CellFX® nsPFA Cardiac Surgery System for the Treatment of Atrial Fibrillation Pulse Biosciences, Inc. announced that it has received the Breakthrough Device Designation from the U.S. FDA for the Company's Cardiac Surgery System for the ablation of cardiac tissue for the treatment of atrial fibrillation (AF). Pulse Biosciences' Cardiac Surgery System with Surgical Clamp is designed to produce durable, continuous transmural ablation lesions during cardiac surgery procedures for the treatment of atrial Fibrillation. The bipolar clamp utilizes the Company’s proprietary nanosecond PFA technology. Based on pre-clinical studies, a single application of less than 2 seconds with the Surgical Clamp creates a consistent, transmural ablation, which is significantly faster, requiring approximately one-twentieth the time of currently available thermal ablation technologies. Also, due to the non-thermal mechanism of action of nano-PFA, there is no risk of thermal spread that may cause undesired injury to collateral tissues, which compares favorably to thermal radiofrequency ablation. The Breakthrough Devices Program is a voluntary program for certain medical devices with the potential to provide more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions, such as atrial fibrillation. The Breakthrough Devices Program is intended to provide patients and health care providers with timely access to medical devices by speeding up development, assessment, and review for premarket approval, 510(k) clearance, and De Novo marketing authorization. Breakthrough Devices must still meet the FDA’s rigorous standards for device safety and effectiveness in order to be authorized for marketing. The Company now plans to pursue the premarket approval (PMA) application pathway for FDA approval to market as opposed to the 510(k) route, and once FDA PMA approved, commercialize the nsPFA Cardiac Surgical System in the United States as a treatment for atrial fibrillation. Once granted by the FDA, a specific treatment indication would permit direct marketing of the treatment benefits provided by the device. The Company expects to begin its pivotal clinical trial for AF in 2025 and will provide additional details on the study and its regulatory and commercial implications later this year.
