Insights

Translational Oncology Analyst

Preclinical lab results show Telomir-1 reduces survival and mitochondrial activity in PANC-1 pancreatic cancer cells; findings are preliminary.

Telomir-1 produced a concentration-dependent reduction in human pancreatic (PANC-1) cell survival and mitochondrial activity, with effects partially reversible by iron re-addition. The program links these observations to modulation of DNA-methylation and iron-dependent histone demethylases, citing effects on MASPIN (SERPINB5), RASSF1A, STAT1, KDM2B, and KDM6B.

Key dependencies and risks include the preclinical setting, the partial iron rescue that indicates multiple mechanisms, and the absence of in vivo or clinical data. The company plans in vivo validation studies and IND preparation, which are necessary next steps before any clinical relevance can be assessed.

Watch for confirmation in animal models and formal IND milestones. Monitor results from planned in vivo validation and any dates tied to IND submission; expect these items over the medium term as preclinical work proceeds.

Findings complement previously announced results in triple-negative breast cancer (TNBC) and prostate cancer models, highlighting Telomir-1's consistent impact on cancer cell survival pathways.

MIAMI, FLORIDA / ACCESS Newswire / October 14, 2025 / Telomir Pharmaceuticals, Inc. (NASDAQ:TELO) ("Telomir" or the "Company"), a preclinical-stage biotechnology company developing therapies that target epigenetic drivers of cancer, aging, and age-related disease, today announced new laboratory findings demonstrating that Telomir-1 kills aggressive pancreatic cancer cells.

Study Summary

In laboratory studies using human pancreatic cancer (PANC-1) cells, Telomir-1 produced a concentration-dependent reduction in cancer cell survival and mitochondrial activity. These data suggest Telomir-1 influences cellular pathways related to energy metabolism and oxidative balance. The findings align with previously reported results in triple-negative breast and prostate cancer models, indicating that Telomir-1 may engage fundamental biological processes involved in cancer cell regulation.

Similar to the observation in TNBC, Telomir-1's effects in pancreatic-cancer cells were partially reversed by iron re-addition, suggesting that Telomir-1's activity in both TNBC and pancreatic cancer involves iron-dependent processes. The incomplete reversal supports the interpretation that additional metabolic or epigenetic mechanisms are also engaged.

Pancreatic-cancer cells are known for metabolic flexibility - the ability to use glucose, lipids, and amino acids to survive in low-oxygen, nutrient-poor environments. TNBC cells, by comparison, rely more heavily on iron-driven oxidative metabolism. The lower sensitivity of pancreatic cells to Telomir-1 in the presence of iron restoration may therefore reflect modulation of broader mitochondrial or energy-control systems, consistent with Telomir-1's function as an epigenetic modulator.

Mechanistic Context: Key Genes and Enzymes

Telomir-1 has previously been shown to influence several tumor suppressor genes and iron-dependent histone demethylases that are also relevant to pancreatic-cancer biology:

• MASPIN (SERPINB5) - A "tumor suppressor shield" that regulates cell migration, invasion, and therapy response. Its loss through hypermethylation correlates with poor prognosis in pancreatic and prostate cancers. Telomir-1 has been observed to reduce MASPIN hypermethylation in preclinical models.

• RASSF1A ("guardian gene") - A regulator of cell-cycle braking and apoptosis, frequently silenced by promoter methylation in pancreatic, breast, and lung cancers. Telomir-1 has previously decreased RASSF1A methylation in a dose-dependent manner.

• STAT1 - A master coordinator of immune surveillance. When hypermethylated, tumors can evade immune detection. Telomir-1 has shown modulation of STAT1 methylation status in laboratory models, informing its potential relevance to immune-related control mechanisms.

• KDM2B (FBXL10) and KDM6B (JMJD3) - Iron-dependent histone demethylases overexpressed in pancreatic and other aggressive cancers, driving transcriptional reprogramming, inflammation, and stem-like tumor behavior. Telomir-1 has demonstrated inhibitory activity against these enzymes.

Together, these previously reported effects provide biological context for Telomir-1's observed activity in pancreatic cancer models. By modulating genes and enzymes that coordinate DNA-methylation, oxidative stress, and cellular energy regulation, Telomir-1 may offer a unifying framework for understanding shared epigenetic and metabolic vulnerabilities across multiple tumor types.

Executive Commentary

Erez Aminov, Chief Executive Officer of Telomir Pharmaceuticals, stated:

"Our mission has always been to understand and address the root biological drivers of disease, not just their downstream symptoms. Pancreatic cancer is one of the hardest and deadliest malignancies known, and these data advance our understanding of how Telomir-1 interacts with the underlying mechanisms that sustain aggressive tumor biology. Each new finding brings us closer to our goal of translating deep science into meaningful innovation."

Dr. Angel, Chief Scientific Advisor of Telomir Pharmaceuticals, added:

"From a scientific standpoint, these results continue to refine our mechanistic understanding of Telomir-1. The differential behavior seen in pancreatic versus breast-cancer models helps us map how Telomir-1 influences iron-dependent and mitochondrial pathways in the context of epigenetic regulation. This type of multi-dimensional insight is precisely what's needed to design smarter, targeted approaches in preclinical oncology research."

Telomir intends to expand its preclinical research into additional cancer models, including leukemia, and to initiate in vivo validation studies as part of its ongoing Investigational New Drug (IND) preparation.

The Unmet Need in Pancreatic Cancer

Pancreatic cancer remains one of the most lethal malignancies, with an estimated 66,440 new U.S. cases and 51,750 deaths projected in 2024 (American Cancer Society). The five-year survival rate is approximately 12%, the lowest among major cancers (National Cancer Institute SEER).

Current standards of care - FOLFIRINOX, gemcitabine plus nab-paclitaxel and selected targeted or immunotherapy combinations - extend survival modestly but are limited by toxicity and the rapid emergence of resistance. The disease's dense stromal barrier, late detection, and ability to rewire its metabolism make it one of the most difficult cancers to treat. This has driven growing interest in therapies that address the epigenetic and metabolic mechanisms enabling tumor persistence.

Why Pancreatic Cancer Remains So Difficult to Treat-and How Telomir-1 Differs

Pancreatic cancer is one of the most complex and treatment-resistant malignancies, driven by a unique combination of biological and environmental challenges. The tumors develop a dense fibrotic stroma that limits drug penetration and oxygen flow, creating a microenvironment that supports survival rather than destruction. These cells also exhibit remarkable metabolic flexibility, switching among glucose, lipid, and amino acid utilization to sustain growth even when nutrients are scarce. This adaptability, together with profound epigenetic dysregulation, enables pancreatic tumors to resist chemotherapy and immune-based therapies alike.

Current front-line regimens-FOLFIRINOX or gemcitabine combined with nab-paclitaxel-attack rapidly dividing cells throughout the body. While these treatments can temporarily slow disease progression, they are often associated with severe fatigue, gastrointestinal distress, immune suppression, and peripheral neuropathy, and the benefit typically lasts only months before resistance emerges.

Telomir-1 represents a fundamentally different approach. Rather than relying on cytotoxic mechanisms that indiscriminately damage dividing cells, Telomir-1 is being studied for its ability to modulate epigenetic and metabolic regulators that underlie cancer cell survival. By influencing pathways that control DNA methylation, histone demethylation, mitochondrial activity, and iron balance, Telomir-1 may help reset the abnormal cellular programs that fuel aggressive cancers. This approach aims to reveal tumor vulnerabilities at their regulatory source - potentially offering a more targeted and mechanistically precise strategy for future development.
