About the REGAIN Study
The clinical trial is expected to enroll up to
20 U.S. patients with recurrent glioblastoma not amenable to surgical resection who have undergone a prior course of central nervous system
radiation. The primary objective of the study is to evaluate the feasibility and safety of the treatment, following the Company’s
promising results from pre-clinical studies. Additional information about the trial can be found at https://www.clinicaltrials.gov/study/NCT06910306
About Alpha Tau Medical Ltd.
Founded in 2016, Alpha Tau is an Israeli oncology
therapeutics company focused on the 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 primarily
affect the tumor and to spare healthy tissue surrounding it. For intracranial use, Alpha DaRT sources are delivered via a specialized
stereotactic delivery system that interfaces with standard real-time neuronavigation platforms, with the goal of precise, image-guided
source placement through minimally invasive burr-hole access without requiring open craniotomy.
Forward-Looking Statements
This press release includes “forward-looking
statements” within the meaning of the Private Securities Litigation Reform Act of 1995. When used herein, words including “anticipate,”
“will,” “plan,” “may,” “continue,” and similar expressions are intended to identify forward-looking
statements. Other than its marketing approval in Japan for unresectable locally advanced or locally recurrent head and neck cancer and
in Israel for products intended to treat Squamous Cell Carcinoma (SCC) of the Skin and Oral Cavity, the Alpha DaRT treatment has not been
approved for commercialization or for use outside of an approved clinical trial. In addition, any statements or information that refer
to the Alpha DaRT treatment in glioblastoma patients, including the timing and content of the conference call and webcast and of the presentation
at the SNO Annual Meeting, the expected enrollment and conduct of the REGAIN trial, the potential benefits and associated risks, safety,
feasibility and efficacy, future applications and uses, and other expectations, beliefs and plans, including with respect to clinical
trials, regulatory approvals and studies, are forward-looking. All forward-looking statements are based upon Alpha Tau’s current
expectations and various assumptions. Alpha Tau believes there is a reasonable basis for its expectations and beliefs, but they are inherently
uncertain. Alpha Tau may not realize its expectations, and its beliefs may not prove correct. Actual results could differ materially from
those described or implied by such forward-looking statements as a result of various important factors, including, without limitation:
(i) Alpha Tau’s ability to receive regulatory approval for its Alpha DaRT technology or any future products or product candidates;
(ii) Alpha Tau’s limited operating history; (iii) Alpha Tau’s incurrence of significant losses to date; (iv) Alpha Tau’s
need for additional funding and ability to raise capital when needed; (v) Alpha Tau’s limited experience in medical device discovery
and development; (vi) Alpha Tau’s dependence on the success and commercialization of the Alpha DaRT technology; (vii) the failure
of preliminary data from Alpha Tau’s clinical studies to predict final study results; (viii) failure of Alpha Tau’s early
clinical studies or preclinical studies to predict future clinical studies; (ix) Alpha Tau’s ability to enroll patients in its clinical
trials; (x) undesirable side effects caused by Alpha Tau’s Alpha DaRT technology or any future products or product candidates; (xi)
Alpha Tau’s exposure to patent infringement lawsuits; (xii) Alpha Tau’s ability to comply with the extensive regulations applicable
to it; (xiii) the ability to meet Nasdaq’s listing standards; (xiv) costs related to being a public company; (xv) changes in applicable
laws or regulations; and the other important factors discussed under the caption “Risk Factors” in Alpha Tau’s annual
report filed on Form 20-F with the SEC on March 9, 2026, and other filings that Alpha Tau may make with the United States Securities and
Exchange Commission. These and other important factors could cause actual results to differ materially from those indicated by the forward-looking
statements made in this press release. Any such forward-looking statements represent management’s estimates as of the date of this
press release. While Alpha Tau may elect to update such forward-looking statements at some point in the future, except as required by
law, it disclaims any obligation to do so, even if subsequent events cause its views to change. These forward-looking statements should
not be relied upon as representing Alpha Tau’s views as of any date subsequent to the date of this press release.
