CHICAGO, Dec. 11, 2025 (GLOBE NEWSWIRE) -- A recent round of open-market purchases marks another display of confidence as the small molecule telomere-targeting cancer therapy by MAIA Biotechnology, Inc. (NYSE American: MAIA) advances through mid- to late-stage clinical development. Newly filed disclosures show that CEO Dr. Vlad Vitoc and other board members acquired approximately 182,445 shares between November 21 and 28, 2025. Insiders’ participation has been viewed by the market as a strong signal of alignment, conviction, and belief in the long-term value creation potential of the ateganosine platform.

The latest insider buying arrives as ateganosine continues to deliver encouraging results. These outcomes have strengthened internal and external confidence that MAIA’s novel telomere-targeting approach may represent a meaningful new therapeutic pathway for patients with advanced non-small cell lung cancer (NSCLC).

Taken together—material insider buying at market prices, sustained insider participation across 2025 financings, and strengthening clinical signals—MAIA’s leadership continues to demonstrate a unified stance: confidence in the company’s strategy, confidence in ateganosine’s growing body of clinical evidence, and confidence in the opportunity ahead as the program advances toward later-stage development. To date, Directors and Officers hold 4,480,120 shares or 12.95% of the company.
