Rhea-AI Filing Summary

Telomir Pharmaceuticals, Inc. reported that a peer-reviewed preclinical study of its lead candidate Telomir-Zn was published in the Journal of Oncology Research and Therapy, Volume 11, Issue 3. The study shows Telomir-Zn depletes intracellular iron to inhibit JmjC histone demethylases (KDMs), enzymes overexpressed in aggressive cancers, leading to tumor-suppressor gene reactivation and reduced tumor growth in prostate and triple-negative breast cancer (TNBC) models.

In TNBC models, Telomir-Zn reduced primary tumor size and significantly curtailed metastatic spread in an HCC1806 model, and showed synergistic tumor reduction when combined with paclitaxel in BT-549 xenografts, while one TNBC model (MDA-MB-231) did not respond. The compound killed iron-dependent TNBC cells at low concentrations while sparing normal cells at concentrations more than 50-fold higher, suggesting a favorable selectivity window. These findings support advancement of Telomir-Zn into a planned Phase 1/2 clinical trial in TNBC under an active IND.

triple-negative breast cancer medical
"suppressing tumor growth in prostate and triple-negative breast cancer (TNBC) models"
Triple-negative breast cancer is a type of breast cancer that lacks three common markers used to identify and treat the disease effectively. Because it doesn’t respond to some targeted therapies, it can be more difficult to treat and may have a more aggressive progression. This impacts the development of new treatments and can influence the outlook for healthcare companies involved in cancer research and pharmaceuticals.
histone demethylases medical
"Telomir-Zn inhibits histone demethylases (KDMs), which aggressive cancer cells overexpress"
Histone demethylases are enzymes that remove small chemical tags from histone proteins, which act like a volume knob that helps control whether particular genes are turned up or down. They matter to investors because drugs or diagnostics that target these enzymes can change disease-related gene activity, creating potential new therapies, revenue streams, and clinical trial catalysts for biotech companies working in cancer, neurological, or inflammatory conditions.
xenograft models medical
"In TNBC human xenograft models, Telomir-Zn reduced primary tumor size"
Xenograft models are laboratory tests in which human tissues or tumors are implanted into animals (commonly mice) so researchers can watch how a disease progresses and how a potential drug behaves in a living body. For investors, these models act like a realistic prototype test: strong positive results can lower the technical risk of a drug program and increase the likelihood of advancing to costly human trials, while failures can signal higher development risk.
epigenetic silencing medical
"elevated KDM activity and abnormal DNA methylation can silence tumor-suppressor genes"
Investigational New Drug (IND) regulatory
"has received Investigational New Drug (IND) clearance from the U.S. Food and Drug Administration"
An investigational new drug (IND) is a drug or biologic that is being tested but has not yet been approved for general use; it is the application and formal status that allows a company to begin human clinical trials under regulator oversight. Investors care because an IND marks the transition from lab work to human testing — like getting a permit to run real-world experiments — which creates important milestones, costs, timelines and regulatory risk that drive a development-stage company's value.

Item 7.01 Regulation FD Disclosure.

 

On August 10, 2026, Telomir Pharmaceuticals, Inc. (the “Company”) issued a press release announcing publication of a peer-reviewed preclinical study titled “Telomir-Zn Modulates Intracellular Iron and Copper to Inhibit JmjC Histone Demethylases and Suppress Tumor Growth in Prostate and Triple-Negative Breast Cancer” in the Journal of Oncology Research and Therapy, Volume 11, Issue 3.

 

The publication demonstrated that Telomir-Zn inhibits histone demethylases (KDMs), which aggressive cancer cells overexpress, to silence tumor-suppressor genes by depleting free intracellular iron. In TNBC cells, iron-rescue experiments proved the mechanism’s specificity. In prostate and TNBC cancer models, the compound reduced primary tumor growth. In a prostate cancer model, Telomir-Zn enabled the reactivation of silenced tumor-suppressor genes by the inhibition of DNA methylation. Notably, Telomir-Zn significantly reduced metastatic dissemination in an HCC1806 TNBC model—a critical finding, as most TNBC patients die from metastatic spread. In TNBC models, Telomir-Zn combined with paclitaxel showed synergistic tumor reduction, suggesting potential for combination approaches.

Telomir Announces Peer-Reviewed Publication Demonstrating Telomir-Zn Suppresses Tumor Growth in TNBC and Prostate Cancer Models

 

Iron-Rescue Experiments Confirm Iron-Dependent Mechanism. Tumor Suppressor Gene Reactivation and Anti-Tumor and Anti-Metastatic Activity Across Multiple Models.

 

MIAMI, Aug. 10, 2026 (GLOBE NEWSWIRE) -- Telomir Pharmaceuticals, Inc. (NASDAQ:TELO), a clinical-stage biotechnology company developing small-molecule therapeutics targeting epigenetic and metabolic drivers of cancer, today announced the peer-reviewed publication of preclinical data of Telomir-Zn suppressing tumor growth in prostate and triple-negative breast cancer (TNBC) models through selective modulation of intracellular iron and copper.

 

The manuscript, titled “Telomir-Zn Modulates Intracellular Iron and Copper to Inhibit JmjC Histone Demethylases and Suppress Tumor Growth in Prostate and Triple-Negative Breast Cancer,” has been published in the Journal of Oncology Research and Therapy, Volume 11, Issue 3. These preclinical findings provide the scientific foundation supporting advancement of Telomir-Zn toward the Company’s planned Phase 1/2 clinical trial in TNBC.

 

Publication Highlights

 

KDM Inhibition: The Target at the Core

 

Histone demethylases, or KDMs, specifically the KDM2, KDM5, and KDM6 families, are often overexpressed in aggressive cancers, where they can promote tumorigenesis by either silencing tumor-suppressor genes or activating oncogenic programs, depending on their substrate specificity and cellular context. Telomir-Zn targets these KDM enzymes by depleting the intracellular iron they require for catalytic activity. This study demonstrates that this KDM-targeting approach translates to meaningful anti-cancer activity.

 

Iron-Dependent Mechanism Proved

 

The study’s most critical finding was direct proof that Telomir-Zn’s anti-cancer activity depends on iron depletion. When researchers added iron back to treated TNBC cells, the compound’s killing effect was significantly reversed. This iron-rescue result eliminates alternative explanations and demonstrates the mechanism is real and specific, not a general toxin or off-target effect.

 

Selective Targeting of Cancer Over Normal Cells

 

Telomir-Zn killed iron-dependent TNBC cancer cells at low concentrations while leaving normal cells unharmed at concentrations more than 50-fold higher. This selectivity window demonstrates the compound preferentially targets cancer cells with elevated iron dependence, a hallmark of aggressive malignancies like TNBC.

 

 

 

 

Tumor Suppressor Gene Reactivation

 

In a prostate cancer model, oral Telomir-Zn suppressed tumor growth and reactivated silenced tumor-suppressor genes (STAT1, GSTP1, RASSF1A, CDKN2A, and MASPIN). In TNBC and prostate cancer, both elevated KDM activity and abnormal DNA methylation can silence tumor-suppressor genes through distinct but complementary epigenetic mechanisms. The compound works through an upstream mechanism distinct from approved drugs that target downstream epigenetic machinery.

 

Anti-Tumor and Anti-Metastatic Activity

 

In TNBC human xenograft models, Telomir-Zn reduced primary tumor size across several cell lines. In HCC1806 xenografts, the compound also significantly reduced metastatic dissemination, a critical finding, as most TNBC patients die from spread disease, not the primary tumor. In BT-549 xenografts, Telomir-Zn combined with paclitaxel produced significantly greater tumor reduction than either drug alone, a finding that suggests potential for combination therapy approaches in the clinic and positions Telomir-Zn as both a monotherapy and a chemotherapy partner. Notably, MDA-MB-231 xenografts did not respond, indicating heterogeneous sensitivity based on tumor-specific iron-metabolism features. It tells us that in the future we could be able to stratify patients based on personalized iron-handling signatures and potentially enrich for responders in future clinical development.

 

Why This Matters for Clinical Development

 

Triple-negative breast cancer remains a significant clinical challenge. Most patients receive chemotherapy as a backbone, with limited options for targeted or precision-based approaches. Current approved therapies and those in development address symptoms of epigenetic dysregulation but do not target the underlying metabolic drivers, specifically, the dysregulated iron homeostasis that fuels overactive KDM enzymes in iron-addicted cancers.

 

This publication establishes dysregulated KDM-driven epigenetic silencing as a fundamental cancer vulnerability that can be targeted through selective iron modulation. Unlike conventional epigenetic drugs that broadly inhibit methylation-modifying enzymes (DNMT or HDAC inhibitors), Telomir-Zn targets the upstream metabolic dependency, excess intracellular iron, that fuels KDM overactivity. By depleting labile iron and disabling KDM enzymes, the compound disrupts epigenetic silencing at its root, enabling tumor-suppressor reactivation. This mechanistically distinct approach addresses a therapeutic gap in the current TNBC treatment landscape.

 

The iron-rescue experiments provide the strongest possible proof that this mechanism is real and specific, enabling clinical strategies for patient selection based on iron-metabolism biomarkers. The preclinical anti-metastatic activity in HCC1806 xenografts is particularly noteworthy, as it suggests potential to address both primary tumor control and disseminated disease, a key unmet need in TNBC.

 

 

 

 

Management Commentary

 

“In several cancer types, cancer cells silence critical tumor-suppressor genes through abnormal DNA methylation, essentially turning off the cell’s brakes,” said Dr. Itzchak Angel, Chief Scientific Advisor of Telomir. “Overactive KDM enzymes also play a role as important drivers of this epigenetic silencing. Current TNBC treatments address downstream consequences of this dysregulation but do not target the KDM-driven mechanism itself. Our data implicates that by reversing the abnormal methylation and by KDM inhibition, Telomir-Zn can reactivate these silenced tumor-suppressor genes, promoting cell killing. We’re seeing tumor suppression and, in some models, reduced metastatic spread. This is a mechanistically different approach to TNBC, and we believe it addresses a fundamental vulnerability that existing therapies don’t. We’re encouraged by the preclinical evidence and eager to test it in patients.”

 

“Triple-negative breast cancer represents one of oncology’s most significant unmet needs,” said Erez Aminov, CEO of Telomir. “Most patients with advanced disease have limited treatment options and poor survival outcomes. We’re excited to advance Telomir-Zn into our Phase 1/2 program under our active IND to test whether this approach can meaningfully improve outcomes for TNBC patients.”
