AlphaTON's Cyncado Therapeutics and Australia's ADDRI to Launch Investigator-Initiated Mesothelioma Clinical Trial of TT-4, Complementing U.S. Plans

Dover, DE and Sydney, Australia, Nov. 12, 2025 (GLOBE NEWSWIRE) -- AlphaTON Capital Corp (Nasdaq: ATON) and its wholly owned oncology-focused subsidiary Tarus Therapeutics, LLC, operating as Cyncado Therapeutics (Cyncado), today announced a non-binding Letter of Intent (LOI) between Australia’s Asbestos and Dust Diseases Research Institute (ADDRI) and Tarus Therapeutics, LLC to conduct an investigator-initiated clinical trial evaluating TT-4, Cyncado’s selective A2B receptor antagonist, in mesothelioma. The Australian trial is planned to enroll approximately 50 patients and will be run in addition to Cyncado’s U.S. mesothelioma activities, subject to a definitive agreement and customary approvals. Highlights ADDRI to sponsor an investigator-initiated clinical trial of TT-4 in mesothelioma in Australia (planned enrollment of 50 patients) Addresses the urgent need after first-line therapy, where there is no widely accepted second-line standard and outcomes remain poor Builds on previously shared preclinical findings supporting evaluation of TT-4 in mesothelioma Cyncado to provide TT-4 and limited support under a definitive agreement Part of an international program running alongside Cyncado’s planned U.S. activities Led by A/Prof Steven Kao (Chris O’Brien Lifehouse/ADDRI) and Dr Melvin Chin (Sir Charles Gairdner Hospital/NCARD) “ADDRI’s leadership in asbestos-related disease makes Australia a compelling setting for a TT-4 investigator-initiated trial,” said Peter Molloy, Chief Executive Officer, Cyncado Therapeutics. “We are building an international mesothelioma program to move quickly, generate decision-quality data, and bring better options closer to patients.” “We exist to improve outcomes for people living with asbestos and dust-related diseases,” said Kim Brislane, Chief Executive Officer, ADDRI. “Australia faces a significant mesothelioma burden. An IIT lets our clinical community evaluate A2B antagonism through a rigorous, patient-focused protocol, and contribute high-quality data that can inform care in Australia and abroad.” About the Investigators A/Prof Steven Kao (Chris O’Brien Lifehouse / ADDRI) - Thoracic medical oncologist and mesothelioma specialist who oversees trials at Chris O’Brien Lifehouse; ADDRI research fellow with a PhD focused on mesothelioma; principal investigator on multiple mesothelioma studies and co-author of peer-reviewed work on biomarkers and treatment response.

Mesothelioma at a glance Mesothelioma is an aggressive, asbestos-linked cancer with poor prognosis: IO has improved first-line outcomes, but most patients relapse. There’s no established second-line standard, making clinical trials a priority, particularly in Australia, which has one of the highest per-capita burdens.
