AlphaTON Capital and Cyncado Therapeutics Share New Mesothelioma Data Supporting TT-4's Path to First- Patient Dosing

Core Insights - AlphaTON Capital Corp and its subsidiary Cyncado Therapeutics presented new findings at the AACR-NCI-EORTC conference, demonstrating that selective adenosine A2B receptor inhibition has a direct anti-tumor effect in mesothelioma cells, reducing PD-L1 expression and modulating YAP signaling [1][2][3] Clinical Development - The new data supports the efficacy of Cyncado's selective A2B receptor antagonist TT-4, which showed better monotherapy activity than anti-PD-1 and improved tumor control when combined with anti-PD-1, leading to increased immune infiltration [2][3] - TT-4 is advancing towards first-patient dosing expected in Q1 2026, with a focus on translating these findings into clinical applications [4][10] Research Collaboration - The research was conducted in collaboration with the Italian Group for Mesothelioma and other institutions, highlighting the importance of partnerships in advancing cancer therapeutics [1][5] Mechanistic Insights - In human mesothelioma models, hypoxia-linked adenosine signaling was found to increase tumor growth and PD-L1 expression, while selective A2B receptor inhibition effectively reduced cell growth and PD-L1 protein levels [3][4] - In vivo studies demonstrated that TT-4 significantly inhibited tumor growth in immunocompetent models, further enhanced by combination therapy with anti-PD-1 [3][4] Company Overview - AlphaTON Capital is focused on building a strategic reserve of TON tokens and developing the Telegram ecosystem, providing institutional-grade exposure to the TON ecosystem while maintaining transparency as a Nasdaq-listed company [6][7] - Cyncado Therapeutics is developing small molecule adenosine receptor antagonists targeting A2A and A2B receptors to overcome immune suppression in oncology, with TT-4 being the lead program [10]
