Exhibit 99.1
Alpha Tau and Samsung Medical Center Sign MOU
to Explore Clinical Trial of Alpha DaRT
®
for Pancreatic Cancer Patients in Korea
- MOU relates to a potential clinical trial
in South Korea, Alpha DaRT’s first, at Samsung Medical Center (SMC) in Seoul, ranked fifth in the world and number one in Korea
in oncology -
- In Korea, only about one in five pancreatic
cancer patients undergo surgery, and the disease’s death rate rose over 6% in 2025, the steepest increase among major cancers -
JERUSALEM, Oct. 22, 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
the signing of an MOU in Seoul, South Korea, with Samsung Medical Center (SMC), regarding
a potential clinical trial in pancreatic cancer patients.
Any such trial would be subject to regulatory and ethics committee approvals.
Pancreatic cancer is one of Korea’s deadliest
cancers. It is now the country’s fourth leading cause of cancer death, and unlike most cancers in Korea, its death rate has continued
to rise. In 2023, 9,748 Koreans were diagnosed with the disease, and its five-year relative survival rate of 17.0% is the lowest of any
cancer in the country. Fewer than one in six patients are diagnosed while the cancer is still confined to the pancreas, and more than
four in ten are diagnosed only after it has already spread to distant organs.
SMC is ranked fifth in the world and number
one in Korea in oncology. Its Pancreatobiliary Cancer Center combines a multidisciplinary team, a fast-track pathway for diagnosis
and treatment, and a high-volume surgical program that has performed more than 4,000 pancreatectomies for pancreatic cancer between
2008 and 2025. (Courtesy of SMC)
Uzi Sofer
, CEO of Alpha Tau, stated:
“Signing
this MOU with Samsung Medical Center, one of the world’s leading medical centers, is an important step forward in our goal to bring
Alpha DaRT to cancer patients wherever they are. With Korea, our pancreatic cancer program could potentially span six countries across
North America, Europe, the Middle East and Asia. I am grateful for SMC’s confidence in Alpha Tau and for the opportunity to explore
the potential of Alpha DaRT to benefit its patients.”
Hee-Chul Kim
, EVP of Samsung Medical Center,
General Director of Samsung Comprehensive Cancer Center (SCCC), stated:
“Pancreatic cancer remains one of the most challenging
cancers to treat, and treatment options are limited for many patients. We hope this MOU will help us explore new possibilities for these
patients. We will carefully review the clinical application of Alpha DaRT and do our best to strengthen our own research capabilities.”
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.
About Samsung Comprehensive Cancer Center
Samsung Comprehensive Cancer Center (SCCC) is
guided by respect for life, striving for excellence in patient care, research, and education to help people lead healthier, happier lives.
Since opening in 2008 as Korea’s first and largest cancer center of its kind, SCCC has continued to expand its capabilities, establishing
the Supportive Care Center (2014), the Proton Therapy Center (2016), the CAR T-Cell Therapy Center (2021), and the Precision Oncology
Therapeutics Center (2022). In 2023, SCCC signed MOUs with Gustave Roussy and Charité to strengthen its global collaboration, and
in 2024 it opened the Institute for Quality of Life in Cancer. In 2026, SCCC achieved ICHOM Level 1 accreditation and signed an MOU with
EORTC. SMC was ranked fifth in the world and first in Korea in oncology in Newsweek’s World’s Best Specialized Hospitals 2027.
