“Ongoing support from our directors reflects their strong conviction in the commercial potential of ateganosine, our first-in-class anticancer treatment for advanced non-small cell lung cancer (NSCLC),” said Vlad Vitoc, M.D., founder and CEO of MAIA. “Consistent insider participation in our 2025 financings strengthens our ability to execute as we advance our pivotal Phase 3 international trial launched this month with first patient dosing.”
Dr. Smith commented, “Our continued support reflects our strong confidence in the scientific differentiation and commercial promise of ateganosine. The initiation of the pivotal Phase 3 trial marks an important value-creation milestone for MAIA.”
Ms. Adelina Louie stated, “I believe MAIA has reached a pivotal stage in advancing life-changing therapies to broad populations of patients with cancer, and I am proud continue to support the Company in my capacity as both an investor and a member of the Board.”

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.
