Alpha Tau (Nasdaq: DRTS) announced on December 9, 2025 that it treated the first patient in a U.S. pilot study of Alpha DaRT for recurrent glioblastoma multiforme (GBM) at The Ohio State University James Cancer Hospital.

The company noted FDA Breakthrough Device Designation and acceptance into the FDA Total Product Life Cycle Advisory Program to accelerate development for GBM patients.

Alpha Tau (NASDAQ: DRTS) announced two abstracts from its pancreatic cancer pilot studies were accepted for presentation at the 2026 ASCO Gastrointestinal Cancers Symposium (Jan 8-10, 2026) in San Francisco.

Alpha Tau treated its first U.S. multi-center pancreatic cancer patient in September 2025; the U.S. trial plans to enroll up to 30 patients with recruitment expected to finish by the end of Q1 2026.
