"We are proud to join ELCC 2025, a premier conference focused directly on the science of thoracic oncology," said Vlad Vitoc, M.D., CEO of MAIA. "Our poster features our latest findings on cytokine Interleukin-6 (IL-6) as a potential predictive immune response biomarker for THIO sequenced with a checkpoint inhibitor. Predictive biomarkers can further illuminate THIO’s unique mechanisms of action which have shown exceptional efficacy in our Phase 2 clinical trial."

About Ateganosine
Ateganosine (THIO, 6-thio-dG or 6-thio-2’-deoxyguanosine) is a first-in-class investigational telomere-targeting agent currently in clinical development to evaluate its activity in Non-Small Cell Lung Cancer (NSCLC). Telomeres, along with the enzyme telomerase, play a fundamental role in the survival of cancer cells and their resistance to current therapies. The modified nucleotide 6-thio-2’-deoxyguanosine induces telomerase-dependent telomeric DNA modification, DNA damage responses, and selective cancer cell death. Ateganosine-damaged telomeric fragments accumulate in cytosolic micronuclei and activates both innate (cGAS/STING) and adaptive (T-cell) immune responses. The sequential treatment with ateganosine followed by PD-(L)1 inhibitors resulted in profound and persistent tumor regression in advanced, in vivo cancer models by induction of cancer type–specific immune memory. Ateganosine is presently developed as a second or later line of treatment for NSCLC for patients that have progressed beyond the standard-of-care regimen of existing checkpoint inhibitors.
