On August 26, 2025, Pulse Biosciences, Inc. (the “Company”) issued a press release announcing the publication of early data from the Company’s clinical study of its CellFX nsPFA Percutaneous Electrode System for the treatment of benign thyroid nodules (the “Study”) in the journal Thyroid. The Study was conducted by Professor Stefano Spiezia as a single-arm First-In-Human feasibility study at the Ospedale del Mare center in Naples, Italy. The CellFX nsPFA Percutaneous Electrode System was used under ultrasound guidance to ablate benign thyroid nodules, as either isolated ablations to assess tissue response (Cohorts 1 & 2) or for full treatment of thyroid nodules with therapeutic intent (Cohort 3). Results showed no intranodular fibrosis or scarring on follow-up ultrasounds and fully treated nodules (Cohort 3) had up to 93% reduction in size at 1 year on ultrasound assessment (average 86% reduction), with symptom relief and >48% reduction as early as 2 weeks.

 

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.
