MAIA Biotechnology (NYSE: MAIA) has outlined key clinical milestones for 2025 in a shareholder letter from CEO Vlad Vitoc. The company's lead compound THIO (ateganosine) is highlighted as the only clinical-stage telomere-targeting anticancer agent in cancer discovery.

Key developments include:

• Phase 2 trial THIO-101 expansion is ongoing with potential FDA filing for accelerated approval in 2026
• Phase 3 THIO-104 trial scheduled to begin mid-2025, with potential filing for early full approval in 2026
• THIO demonstrates exceptional efficacy in advanced non-small cell lung cancer (NSCLC)
• Multiple additional THIO trials planned for various cancer indications

The company is pursuing multiple regulatory pathways for THIO in NSCLC treatment, targeting significant market opportunities in hard-to-treat cancers with unmet medical needs.

MAIA Biotechnology (NYSE: MAIA) announced its selection to present a poster at the European Lung Cancer Congress 2025 (ELCC 2025) in Paris, France, from March 26-29. The presentation will focus on cytokine Interleukin-6 (IL-6) as a potential predictive biomarker for THIO treatment response in advanced non-small cell lung cancer (NSCLC).

The poster will highlight findings related to THIO's mechanisms of action when sequenced with checkpoint inhibitors, following exceptional efficacy demonstrated in the company's Phase 2 clinical trial. The ELCC, a program of the European Society for Medical Oncology (ESMO), brings together key multidisciplinary societies in thoracic oncology to advance science and improve lung cancer specialist practices.

MAIA Biotechnology (NYSE: MAIA) has published preclinical data in Naunyn-Schmiedeberg's Archives of Pharmacology regarding their novel THIO dimer compound. The study, published on February 15, 2025, demonstrates that THIO and its dimer form effectively inhibit Glutathione S-transferase Pi (GSTP1), an enzyme important in cancer progression and chemoresistance.

The research reveals the compound's potential dual mechanism of action for enhancing standard cancer treatments and addressing drug resistance. As part of MAIA's second-generation research platform, which has developed over 80 THIO-like compounds, this breakthrough aims to identify telomere-targeting compounds with improved cancer cell specificity and increased anticancer activity.

The findings suggest that the dimerized form of THIO could enhance chemotherapeutic efficacy through GSTP1 targeting, potentially offering new strategies for combating drug-resistant cancers.
