Alpha Tau Medical Ltd. reported a clinical milestone: the first recurrent glioblastoma patient treated with its Alpha DaRT therapy outside the United States, and the first in Israel, at Hadassah University Medical Center in Jerusalem under the ALL broad-access protocol.
The procedure used Alpha Tau’s proprietary brain applicator with real-time stereotactic neuro-navigation to deliver Alpha DaRT sources through a single minimally invasive burr-hole, and was completed safely without unexpected complications. Glioblastoma is described as the most common and most lethal primary adult brain tumor, with about 160,000 new global cases annually and near-inevitable recurrence within 6–9 months.
Alpha Tau highlights this case as part of its broader glioblastoma program, which also includes the multicenter U.S. REGAIN trial in recurrent GBM, and positions Alpha DaRT as a potential option for patients with few remaining standard treatments.
Alpha Tau Medical Ltd. submitted a Form 144 notice indicating an intended sale of 17,500 Ordinary Shares through Oppenheimer & Co.

Alpha Tau Medical Ltd. reports that the FDA has cleared it to complete enrollment in its U.S. REGAIN trial of Alpha DaRT for recurrent glioblastoma, allowing recruitment of the final seven of up to ten patients. Two additional leading U.S. academic cancer centers have been authorized as clinical sites, broadening access and expertise for the study.
Early interim data from the first three patients treated showed 100% local disease control, a 67% complete response rate by RANO criteria, and one associated grade 3 serious adverse event that resolved, with no unanticipated toxicities and no local or distant recurrences at the cutoff date. The trial focuses on patients with recurrent glioblastoma who have very limited treatment options, and builds on prior FDA recognition of Alpha DaRT through Breakthrough Device Designation and participation in the Total Product Life Cycle Advisory Program.

Alpha Tau Medical entered a long-term collaboration and supply agreement with Tolmar, granting Tolmar exclusive U.S. commercialization rights for Alpha DaRT in prostate cancer, with an option to expand into bladder cancer. Tolmar will pay an initial $15.0 million to expand Alpha Tau’s manufacturing, up to $161.5 million in clinical, regulatory and commercial milestone payments for the first prostate indication, and 60% of net sales for product supply. Concurrently, Tolmar agreed to a private placement of 1,668,057 ordinary shares at $11.99 per share, providing expected gross proceeds of $20.0 million to Alpha Tau for general corporate purposes, with the potential for an additional $5.0 million equity investment if it exercises the bladder cancer option.
Alpha Tau Medical Ltd. reported new clinical data on its Alpha DaRT® alpha-radiation therapy for pancreatic ductal adenocarcinoma, based on a pooled analysis of three prospective Phase I/II studies.
Patients treated with Alpha DaRT after first-line chemotherapy reached median overall survival of 11.2 months in metastatic disease and 11.1 months in locally advanced disease from trial enrollment, compared with about 4–6 months and about 9 months, respectively, for second-line chemotherapy in published historical data. The safety profile appeared favorable, with treatment-associated adverse events in 36% of subjects and Grade ≥3 events in 9%, no treatment-related deaths, no chronic toxicity, and all Grade ≥3 events resolving.
The company notes these results support the potential feasibility and safety of Alpha DaRT as a one-time, minimally invasive intratumoral treatment and points to the next step of completing recruitment in the multicenter U.S. IMPACT pancreatic cancer trial.
