MAIA Biotechnology (NYSE American: MAIA) announced the publication of interim clinical data from its Phase 2 THIO-101 trial in the peer-reviewed journal Cells. The manuscript, focused on "Perioperative Management of Non-Small Cell Lung Cancer in the Era of Immunotherapy," was authored by researchers from Turkey and the U.S., including MAIA's scientific team.

The publication highlights MAIA's novel combination strategy using ateganosine sequenced with a checkpoint inhibitor, which has shown promising results in addressing the challenge of patient resistance to conventional immunotherapies. This development represents a potential breakthrough for patients with high unmet medical needs in non-small cell lung cancer treatment.

MAIA Biotechnology (NYSE American: MAIA) ha annunciato la pubblicazione su Cells di dati clinici intermedi del suo studio di Fase 2 THIO-101. Il manoscritto, intitolato "Gestione perioperatoria del carcinoma polmonare non a piccole cellule nell'era dell'immunoterapia", è stato redatto da ricercatori turchi e statunitensi, incluso il team scientifico di MAIA.

La pubblicazione mette in luce la strategia combinata innovativa di MAIA basata su ateganosina sequenziata con un inibitore del checkpoint, che ha mostrato risultati promettenti nel superare la resistenza dei pazienti alle immunoterapie convenzionali. Questo progresso potrebbe rappresentare una svolta per i pazienti con grandi bisogni terapeutici insoddisfatti nel trattamento del carcinoma polmonare non a piccole cellule.

MAIA Biotechnology (NYSE American: MAIA) anunció la publicación en la revista Cells de datos clínicos interinos de su ensayo de Fase 2 THIO-101. El manuscrito, titulado "Manejo perioperatorio del cáncer de pulmón de células no pequeñas en la era de la inmunoterapia", fue elaborado por investigadores de Turquía y EE. UU., incluido el equipo científico de MAIA.

La publicación destaca la novedosa estrategia combinada de MAIA que emplea ateganosina secuenciada con un inhibidor del checkpoint, la cual ha mostrado resultados prometedores para afrontar la resistencia de los pacientes a las inmunoterapias convencionales.

CHICAGO, Aug. 27, 2025 (GLOBE NEWSWIRE) -- MAIA Biotechnology, Inc. (NYSE American: MAIA) (“MAIA�, the “Company�), a clinical-stage biopharmaceutical company focused on developing targeted immunotherapies for cancer, today announced that a manuscript detailing developments in its Phase 2 THIO-101 clinical trial was accepted and published in the international peer-reviewed open access scientific journal, , in a special issue, “Cellular Mechanisms of Anti-Cancer Therapies�

The manuscript, titled �,� was authored by a group of oncology researchers in Turkey and the U.S. including MAIA scientists Sergei Gryaznov, Ph.D., Chief Scientific Officer and Ilgen Mender, Director of Biology Research, along with MAIA Scientific Advisory Board members Z. Gunnur Dikmen, M.D., Ph.D. and Saadettin Kiliçkap, M.D., M.Sc.

MAIA Chairman and CEO Vlad Vitoc, M.D. commented, “The importance of the findings published in Cells cannot be overstated. While conventional immunotherapies have expanded treatment options for patients, intrinsic and acquired resistance by patients remains a challenge. Our novel combination strategy of ateganosine sequenced with a checkpoint inhibitor stands out, showing encouraging results in a population with high unmet medical need.�

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 of 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.
