JERUSALEM, Aug. 11, 2025 (GLOBE NEWSWIRE) -- Alpha Tau Medical Ltd. ("Alpha Tau", or the “Company”) (NASDAQ: DRTS, DRTSW), the developer of the innovative alpha-radiation cancer therapy Alpha DaRT®,reported second quarter 2025 financial results and provided a corporate update.

"The Company's focus activities continue to coalesce, with an increasing emphasis on U.S. clinical trials, priority indications in internal organs, and preparations for commercial scale-up," said Alpha Tau Chief Executive Officer Uzi Sofer. "All four U.S. IDEs are active: Our pivotal skin cancer ReSTART (Recurrent SCC Treatment with Alpha DaRT Radiation Therapy) trial continues to recruit patients actively and is nearing completion; we expect to commence treatment shortly in our trial in immunocompromised patients as well as the pilot IMPACT (Intratumoral Pancreatic Alpha Combination Trial) study; and the GBM study should initiate later in 2025. In parallel we are also deepening our focus on pancreatic cancer, with studies expected to launch shortly in France and Italy. And our push towards commercialization continues: a PMDA response is expected imminently, potentially opening up new commercial opportunities for the Company, and we expect to complete our first phase of construction shortly in our commercial-scale facility in Hudson, New Hampshire, which should be ready to manufacture Alpha DaRT treatments in early 2026."

·In April, Alpha Tau announced receipt of an IDE from the FDA to conduct a U.S. pilot study of Alpha DaRT in patients with recurrent glioblastoma multiforme (GBM), a highly aggressive brain cancer with an estimated average survival rate of only 8 months. The clinical trial is expected to enroll up to ten U.S. patients with recurrent glioblastoma not amenable for surgical resection who have undergone a prior course of central nervous system radiation, building on the Breakthrough Device Designation received from the FDA for this indication.

Research and Development expenses for the six months ended June 30, 2025 were $14.2 million, compared to $13.3 million for the same period in 2024, primarily due to an increase in employee compensation and benefits and third-party contractor expenses, reflecting increased clinical activities, as well as decreased government grants, offset by lower costs of raw materials, share-based compensation expenses and travel expenses.

Marketing expenses for the six months ended June 30, 2025 were $0.9 million, compared to $1.1 million for the same period in 2024, due to decreased employee compensation and benefits and decreased marketing conference activities.

General and Administrative expenses for the six months ended June 30, 2025 were $3.9 million, compared to $3.0 million for the same period in 2024, primarily due to increased employee compensation and benefits, including share-based compensation and professional fees (including legal, financing and IR expenses), offset by a decrease in travel expenses and D&O insurance costs.

Financial income, net, for the six months ended June 30, 2025 was $0.3 million, compared to $2.1 million for the same period in 2024, primarily due to a decrease in interest from bank deposits, and changes in foreign exchange rates.

For the six months ended June 30, 2025, the Company had a net loss of $18.8 million, or $0.25 per share, compared to a net loss of $15.4 million, or $0.22 per share, in the six months ended June 30, 2024.

As of June 30, 2025, the Company had cash and cash equivalents, short-term deposits and restricted deposits of $83.3 million, compared to $62.9 million at December 31, 2024.

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.

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.
