Vlad Vitoc, M.D., Founder and Chief Executive Officer of MAIA, commented, "Enrollment and dosing in our Phase 3 study is progressing at a strong pace. Based on this early momentum, we are targeting up to 100 patients by year-end and expect to have sufficient survival data to conduct an interim analysis in 2027."

Dr. Vitoc has previously stated that statistical assessments of MAIA’s lead therapeutic, ateganosine, suggest a high probability of technical success in the THIO-104 full approval trial if Phase 3 data is consistent with Phase 2 THIO-101 trial results. Median overall survival was 17.8 months in parts A and B of the Phase 2 trial. With chemotherapy, which is the standard utilized treatment for 3L NSCLC patients, expected survival in a heavily pre-treated population is 5.8 months.1

Ateganosine is a first-of-its-kind dual mechanism therapy designed to break down telomere structure and function in cancer cells while inducing immune activation. As a potential breakthrough therapeutic, ateganosine holds substantial commercial opportunity in a projected $70 billion global NSCLC treatment market by 2030.2

The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for ateganosine as a 3L NSCLC treatment.

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.

About THIO-104 Phase 3 Clinical Trial

THIO-104 is a multicenter, open-label, randomized Phase 3 clinical trial, designed to evaluate ateganosine’s telomere-targeting anti-tumor activity when followed by PD-(L)1 inhibition in patients with advanced third-line NSCLC who previously did not respond or developed resistance to treatment regimens containing checkpoint inhibitor and/or chemotherapy and have progressed. The trial has two primary objectives: (1) to assess the clinical efficacy of ateganosine compared to investigator’s choice of chemotherapy, using median Overall Survival (OS) as the primary clinical endpoint (2) to evaluate the safety and tolerability of ateganosine in sequential combination with a checkpoint inhibitor. For more information on this Phase 3 trial, please visit ClinicalTrials.gov using the identifier NCT06908304.

mHSPC is a diverse disease state with widely variable outcomes, requiring complex treatment decisions that can significantly impact both survival and quality of life. While traditional clinical factors provide general prognostic insight, they do not offer individualized risk. The ArteraAI Prostate Test (mHSPC) addresses this gap by delivering a patient‑specific estimate of 5‑year prostate cancer–specific mortality (PCSM) in patients treated with androgen deprivation therapy (ADT) plus an androgen receptor pathway inhibitor (ARPI).

"Artera’s platform was built to bring greater clarity to cancer treatment decisions," said Andre Esteva, CEO of Artera. "With our expansion into metastatic hormone-sensitive prostate cancer, we are excited to leverage our validated MMAI approach for a more complex stage of disease, helping guide treatment decisions with greater confidence."

The ArteraAI Prostate Test (mHSPC) builds on Artera’s established biopsy‑based MMAI model used in localized prostate cancer and was further validated in patients with mHSPC receiving ADT plus ARPI as significantly prognostic for prostate cancer–specific mortality.

"As treatment options for metastatic hormone-sensitive prostate cancer have evolved, tools to accurately assess individual patient risk in the context of modern combination therapy have not fully evolved alongside them," said Calvin Chao, MD, PhD, Vice President of Medical Science at Artera. "This clinically validated test is poised to help clinicians better tailor treatment intensity and duration to the individual patient."

The ArteraAI Prostate Test (mHSPC) is available through Artera and its commercial partner, Tempus, supporting broad and convenient access within existing clinical workflows.

Under the agreement, Natera will assess CytoDyn clinical trial samples from the CLOVER Phase 2 study (ClinicalTrials.gov Identifier: NCT06699836) in patients with mCRC. SignateraTM, Natera’s personalized assay for the detection of molecular residual disease (MRD), will be used to evaluate ctDNA dynamics and molecular response patterns associated with leronlimab treatment.

Natera will also provide customized real-world data (RWD) analyses leveraging its proprietary oncology database, which is the largest multi-timepoint early- and late-stage oncology dataset with more than 2 million plasma timepoints and enriched clinical and imaging records. By integrating molecular response data from its MRD testing platform with curated electronic medical record (EMR) data, this multimodal dataset enables analyses of patient populations, treatment patterns, ctDNA response rates, and response dynamics across diverse clinical settings. Together, these capabilities are expected to generate insights into molecular response and disease progression that may help inform future clinical development of leronlimab, including clinical trial design, biomarker-driven patient selection strategies, and broader translational research efforts.

The collaboration builds on CytoDyn’s growing oncology program and follows completion of enrollment in the CLOVER study, which is evaluating leronlimab in combination with trifluridine/tipiracil (TAS-102) and bevacizumab in patients with previously treated mCRC. The collaboration is also expected to complement ongoing translational and biomarker analyses from the study aimed at further characterizing treatment response and informing future development strategies.

"Signatera has become an increasingly important tool in precision oncology and clinical development," said Jacob Lalezari, M.D., chief executive officer, CytoDyn. "Through this collaboration, we expect to gain valuable insights into ctDNA response kinetics and disease progression that may help guide future development strategies for leronlimab in colorectal cancer and potentially other solid tumor indications."

"We are pleased to partner with CytoDyn and provide their team with insights derived from one of the largest and most comprehensive real-world molecular oncology data platforms," said Matt Love, vice president, biopharma data & AI partnering, Natera. "Our platform enables biopharma partners to better understand disease biology, treatment response, and patient outcomes, helping inform key development decisions throughout the drug development lifecycle."
