Alpha Tau Announces First-Ever Oral Presentation of Alpha DaRT® Pancreatic Cancer Data at Digestive Disease Week (DDW) 2026

JERUSALEM, March 31, 2026 (GLOBE NEWSWIRE) -- Alpha Tau Medical Ltd. (Nasdaq: DRTS, DRTSW) (“Alpha Tau”), the developer of the innovative alpha-radiation cancer therapy Alpha DaRT^® today announced that an abstract presenting results of two clinical trials in Jerusalem in patients with pancreatic cancer has been accepted for an oral presentation at Digestive Disease Week (DDW) 2026, the world’s premier international gastroenterology conference. This marks the first time that clinical results of Alpha DaRT in pancreatic cancer patients have been selected for presentation at a major gastroenterology conference.

The abstract, entitled “Updated Results of Feasibility, Safety, and Tumor Control in Two First-In-Human Trials of a Novel Alpha-Emitting Radionuclide for Pancreatic Adenocarcinoma,” has been selected for podium presentation in the Pancreatic Cancer I: Diagnosis and Treatment session on Saturday, May 2, 2026 at 10:30am (Central). The presentation will be led by study Principal Investigator Dr. Harold Jacob, Director of Advanced Gastrointestinal Endoscopy at Hadassah University Medical Center, and is based on combined data from two clinical protocols conducted at Hadassah Medical Center in Jerusalem, Israel.

“The acceptance of this abstract for an oral presentation at DDW is an important milestone for Alpha Tau” stated Uzi Sofer, CEO of Alpha Tau, “It reflects the growing recognition of the potential of our technology to address this devastating disease. With the vast majority of pancreatic cancer patients deemed inoperable at diagnosis, Alpha DaRT seeks to offer a truly novel approach for both locally advanced and metastatic patients, and we look forward to sharing these data at DDW.”

Dr. Harold Jacob, commented, “I am gratified that our work has been selected for an oral presentation at DDW. As the first clinical data of Alpha DaRT in pancreatic cancer to be presented at a major gastroenterology forum, this acceptance highlights the importance and potential of this technology. Alpha DaRT is designed to be uniquely suited for delivery by gastroenterologists via EUS, hopefully positioning our specialty at the forefront of a new era in pancreatic cancer therapy.”

Dr. Robert Den, Chief Medical Officer of Alpha Tau, commented, “The selection of this abstract for an oral presentation at DDW is a testament to the scientific rigor and clinical significance of the work conducted at Hadassah, and of course to Alpha Tau’s excellent investigational technology. These foundational studies have been instrumental in informing our clinical development program, including the IMPACT pilot study now actively enrolling in the U.S., as well as our ongoing work toward a future pivotal study. The full data will be presented at DDW in May.”

About Alpha Tau Medical Ltd.

Founded in 2016, Alpha Tau is an Israeli oncology therapeutics company that focuses on research, development, and potential commercialization of the Alpha DaRT for the treatment of solid tumors. The technology was initially developed by Prof. Itzhak Kelson and Prof. Yona Keisari from Tel Aviv University.

About Alpha DaRT^®

Alpha DaRT (Diffusing Alpha-emitters Radiation Therapy) is designed to enable highly potent and conformal alpha-irradiation of solid tumors by intratumoral delivery of radium-224 impregnated sources. When the radium decays, its short-lived daughters are released from the sources and disperse while emitting high-energy alpha particles with the goal of destroying the tumor. Since the alpha-emitting atoms diffuse only a short distance, Alpha DaRT aims to mainly affect the tumor, and to spare the healthy tissue around it.
