On March 12, 2026, Pulse Biosciences, Inc. (the “Company”) issued a press release announcing the first enrollment of patients in the investigator-sponsored clinical study of its proprietary Vybrance™ Percutaneous Electrode System (the “Vybrance System”) as a potential treatment for papillary thyroid microcarcinoma, a small, slow-growing, and most common form of thyroid cancer (the “Study”). The initial procedures were successfully completed at Sarasota Memorial Health Care System in Sarasota, Florida, and The University of Texas MD Anderson Cancer Center in Houston, Texas. The multicenter, prospective, feasibility study will evaluate the safety and effectiveness of the Vybrance System in treating papillary thyroid cancer tumors less than 1.5cm in size. The Vybrance System consists of a percutaneous needle electrode for use with the Company’s proprietary nPulse™ Console, and the electrode is designed to harness and deliver the key advantages of Nanosecond Pulsed Field Ablation™ (nsPFA™) energy, enabling precise, nonthermal removal of cellular tissue without damage to noncellular structures or inducing thermal necrosis. A total of thirty patients are planned for enrollment. The first patient was enrolled and treated by Dr. Ralph P. Tufano, Director of the Multidisciplinary Thyroid and Parathyroid Center at Sarasota Memorial, while two subsequent cases were completed by Principal Investigator, Dr. Victoria Banuchi, Associate Professor of Head & Neck Surgery at UT MD Anderson. The Vybrance System previously received U.S. Food and Drug Administration (FDA) 510(k) clearance for the ablation of soft tissue and is now being evaluated under an Investigational Device Exemption (IDE) specifically for thyroid cancer applications. The Study is funded in part by the Company.
A copy of the press release related to the matters set forth herein is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
