JERUSALEM, Jan. 05, 2026 (GLOBE NEWSWIRE) -- Alpha Tau Medical Ltd . (Nasdaq: DRTS, DRTSW) ("Alpha Tau", or the “Company”), the developer of the innovative alpha-radiation cancer therapy Alpha DaRT ® today announced the submission of the first module of its pre-market approval (PMA) application to the U.S. Food and Drug Administration (FDA), following the FDA’s previous decision to allow the Company to use the more flexible modular approach. The Company submitted the module as part of an application for the use of Alpha DaRT in treating recurrent cutaneous squamous cell carcinoma (cSCC), the second most common form of skin cancer, for patients not indicated for surgery or standard radiation therapy, and for whom no curative systemic treatment is available. This module is focused on comprehensive documentation with respect to non-clinical studies as required under the PMA application.

Uzi Sofer, CEO of Alpha Tau, stated, “Alpha Tau continues its fast pace of activity, charging forward in our pursuit of potential marketing authorizations across a wide range of tumors, with an eye toward future commercialization. The decision by the FDA to allow us to submit our PMA in a modular form will hopefully allow for ongoing FDA review and feedback as each module is submitted, and we look forward to this dynamic and efficient authorization review process with the FDA.”

Yaniv Sagie, VP Quality and Regulatory Affairs, added, "Thank you to our outstanding team for this great accomplishment, our first PMA module submission, and for all of the other achievements working with regulators around the world. I appreciate the support of our advisors who work closely with us and hope to accomplish great things for Alpha Tau together."

Alpha Tau is currently conducting its multi-center pivotal ReSTART study exploring the use of Alpha DaRT in recurrent cSCC, one of five clinical trials currently approved in the U.S., and anticipates completing patient recruitment in Q1 2026. Alpha Tau has received Breakthrough Device Designation from the FDA in this indication as well as for recurrent glioblastoma multiforme (GBM) and recurrent squamous cell carcinoma of the oral cavity with similar criteria, and is also part of the FDA Total Product Life Cycle Advisory Program (TAP) to accelerate market access for the potential treatment of recurrent GBM.

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.
