AlphaTON (Nasdaq:ATON) and Cyncado Therapeutics: Preclinical Mesothelioma Data Show Direct A2B Tumor Activity; TT-4 Achieved >90% Tumor Growth Inhibition; First-Patient Dosing on Track for Q1 2026
Dover, DE, Oct. 27, 2025 (GLOBE NEWSWIRE) -- AlphaTON Capital Corp (NASDAQ:ATON) and its wholly owned oncology-focused subsidiary Tarus Therapeutics, LLC, operating as Cyncado Therapeutics (Cyncado), today issued a recap of data presented on Saturday at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in Boston.
The poster showed that selective A2B receptor inhibition produces direct anti-tumor activity in both epithelial and non-epithelioid mesothelioma models, reduces tumor PD-L1 alongside decreased pCREB in a human epithelioid mesothelioma cell system, and that TT-4 monotherapy outperformed anti-PD-1 with additional activity in combination. TT-4 remains on track for first-patient dosing in Q1 2026.
"With data now in the public domain showing >90% tumor growth inhibition for TT-4 plus anti-PD-1 and TT-4 monotherapy outperforming anti-PD-1, we are executing toward first-patient dosing in Q1 2026," said Peter Molloy, Chief Executive Officer of Cyncado Therapeutics. "These findings confirm that selective A2B inhibition exerts a direct anti-tumor effect across mesothelioma subtypes, reduces PD-L1, and drives immune activation consistent with durable response potential.
Key takeaways from the poster
- Direct tumor effect across subtypes: Blocking the A2B receptor produced direct anti-tumor activity in both epithelial and non-epithelioid mesothelioma models
- Quantified anti-tumor activity: TT-4 + anti-PD-1 cut tumor growth by more than 90% in vivo; TT-4 alone outperformed anti-PD-1, with additive benefit in combination
- Mechanistic evidence: Selective A2B inhibition decreased pCREB resulting in lowered PD-L1 expression in human mesothelioma spheroids; in murine models TT-4 blocked NECA-induced pCREB and drove in-vivo tumor control
- Immune activation: Combination therapy was associated with increased immune-effector infiltration, consistent with durable immune response
- Advancing to clinic: TT-4 is IND-enabled and remains on track for first-patient dosing in Q1 2026
Next steps
Cyncado is using these findings to finalize clinical development plans for TT-4 in mesothelioma, with first patient dosing on track for Q1 2026.
