Alpha Tau Medical Announces Full Year 2023 Financial Results and Provides Corporate Update

Alpha Tau Medical Ltd. (“Alpha Tau”, or the “Company”) (NASDAQ: DRTS, DRTSW), the developer of the innovative alpha-radiation cancer therapy Alpha DaRT™, reported full year 2023 financial results and provided a corporate update.

“2023 was an incredibly productive year, as we launched our ReSTART pivotal U.S. multi-center trial in recurrent cutaneous squamous cell carcinoma, which is expected to complete recruitment in the second half of 2024, and as we initiated a number of feasibility trials in difficult-to-treat internal organ tumors with high unmet need,” stated Alpha Tau CEO Uzi Sofer. "We saw meaningful inflection points delivered by the end of 2023, including strong interim safety and feasibility data from our pancreatic cancer trial in Montreal, with initial signs of dose response, and our PMDA submission in Japan for pre-market approval. In parallel, we continue to advance our commercial planning activities and to solidify our supply chain, which was recently bolstered by both a valuable land grant in Jerusalem that is expected to increase our future manufacturing capacity, as well as by the leasing of a second manufacturing site in the United States. In 2024, we are focused on completing patient recruitment in our U.S. pivotal ReSTART study and our pancreatic cancer pilot study in Canada, and on beginning to treat patients in studies targeting a number of other internal organs. We are also exploring the addition of new clinical trials in the U.S., based upon recent positive regulatory feedback. We expect to begin work on the construction of our second U.S. facility, in Hudson, NH, and on the construction plans for our second facility in Jerusalem. Alpha Tau expects to remain adequately capitalized to support all of these programs over the coming years.”

Recent Corporate Highlights:

• In October, the Company announced that it had entered into a long-term lease agreement for a standalone building of over 14,000 rentable square feet in Hudson, NH, with the intention of erecting the Company’s second U.S. manufacturing site, alongside its first site in nearby Lawrence, MA.
• In October, the Company announced that Dr. Stephen Hahn, a former commissioner of the U.S. Food and Drug Administration (“FDA”) and a distinguished expert in the field of radiation oncology and translational clinical research, joined its Scientific Advisory Board.
• In November, the Company announced that Japan’s Pharmaceuticals and Medical Devices Agency (“PMDA”) accepted Alpha Tau’s submission requesting shonin pre-market approval of Alpha DaRT in patients with recurrent head and neck cancer, following multiple pre-submission consultation meetings with the PMDA per common practice in Japan.
• In November, the Company announced interim results from treatment of the first five patients in the Company’s safety and feasibility trial in Montreal, Canada, examining the use of Alpha DaRT to treat advanced pancreatic cancer. The Alpha DaRT procedure was deemed technically successful in all five cases, with Alpha DaRT sources successfully inserted into the target tumors. There were no reported serious adverse events deemed related to the product, and the only reported adverse events deemed possibly related to the product were of severity grade 1 (mild). In addition, despite the conservative and gradual step-up of tumor coverage from minimal initial levels, three of the five patients demonstrated stable disease responses at four weeks after treatment, and one was upgraded to partial response at 69 days after treatment.

R&D expenses for the year ended December 31, 2023 were $26.4 million, compared to $20.9 million in 2022, due to increased employee headcount, compensation and benefits, including share-based compensation, increased operating costs, and increased pre-clinical study and clinical trial expenses, particularly in our U.S. ReSTART trial, with a smaller offset through government grants from the Israel Innovation Authority.

Marketing expenses for the year ended December 31, 2023 were $1.9 million, compared to $1.0 million for 2022 due to increased employee compensation and benefits, including share-based compensation, and the hiring of our chief commercial officer.

G&A expenses for the year ended December 31, 2023 were $7.3 million, compared to $10.3 million for 2022, due to to decreased professional fees (including D&O insurance), and costs associated with our financing transaction in the first quarter of 2022.

Financial expenses (income), net, for the year ended December 31, 2023 were $(6.5) million, compared to $1.6 million for 2022, due to revaluation of warrants and an increase in interest from bank deposits, offset by changes in foreign exchange rates.

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.

About Alpha Tau Medical, Ltd.

Founded in 2016, Alpha Tau is an Israeli medical device 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.
