Item 7.01 Regulation FD Disclosure Disclosure
Material non-public information disclosed under Regulation Fair Disclosure, often investor presentations or guidance.
Item 9.01 Financial Statements and Exhibits Exhibits
Financial statements, pro forma financial information, or exhibit attachments filed with this report.
Press release date September 14, 2026 Date of Telomir-Zn osteosarcoma research announcement
Clinical trial phase Phase 1/2 Planned Telomir-Zn trial in advanced or metastatic TNBC under an active IND
Osteosarcoma models evaluated 3 cell lines HOS (human), D17 (canine), Abrams (canine) assessed for Telomir-Zn activity
triple-negative breast cancer medical
"advanced or metastatic triple-negative breast cancer (“TNBC”), which is advancing"
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.
osteosarcoma medical
"osteosarcoma cell line models: HOS (human), D17 (canine), and Abrams"
A rare but aggressive form of bone cancer that usually starts in cells that build bone, most often affecting the long bones of the arms and legs. For investors, it matters because the disease’s severity, patient numbers, and difficulty of treatment shape the market for drugs and medical devices, influence clinical trial design and regulatory reviews, and can drive the potential value or risk of companies developing new therapies—think of it as a small but high-stakes market niche.
Investigational New Drug regulatory
"under an active Investigational New Drug application cleared by the U.S."
An investigational new drug is a medication that is still being tested in clinical trials to determine if it is safe and effective for treating a specific condition. For investors, it represents a potential breakthrough that could lead to a new treatment and significant financial gains if successful, but also carries risks since it has not yet been approved for widespread use.
epigenetic medical
"targeting epigenetic and metabolic drivers of cancer"
Epigenetic describes changes that alter how genes are turned on or off without changing the underlying DNA sequence, similar to flipping light switches or adjusting software settings that control a machine. For investors, epigenetic mechanisms matter because they create new targets for drugs, diagnostics, and therapies that can modify disease processes or patient responses, potentially leading to novel products, market opportunities, and long-term revenue streams.
histone demethylases medical
"inhibition of iron-dependent histone demethylases (KDMs), which reverses"
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.

Telomir Announces Research with The Ohio State University Demonstrating In-Vitro Anti-Cancer Activity in Human and Canine Osteosarcoma Models

 

Preclinical Findings Support Parallel Development Pathway in Canine Osteosarcoma as TNBC Program Advances Toward Site Initiation

 

 

MIAMI, Sept. 14 (GLOBE NEWSWIRE) — Telomir Pharmaceuticals, Inc. (NASDAQ:TELO), a clinical-stage biotechnology company developing small-molecule therapeutics targeting epigenetic and metabolic drivers of cancer, announced new research findings from The Ohio State University College of Veterinary Medicine demonstrating that Telomir-Zn produces inhibition of cell growth across human and canine osteosarcoma models. The findings establish a translational foundation for evaluating the compound in a naturally occurring disease setting while the company’s TNBC program simultaneously advances toward site initiation and Phase 1/2 patient enrollment.

 

Research Findings

 

Conducted under the direction of Shay Bracha, DVM, MS, DACVIM (Oncology) at Ohio State’s College of Veterinary Medicine, the study examined Telomir-Zn across three osteosarcoma cell line models: HOS (human), D17 (canine), and Abrams (canine). Researchers evaluated the dose-dependent anti-tumor activity of the compound across all three models.

 

All three osteosarcoma cell lines demonstrated growth inhibition at similar low drug concentrations. “Osteosarcoma in large-breed dogs remains devastating, with limited treatment options and poor outcomes,” noted Bracha, an associate professor at The Ohio State University College of Veterinary Medicine. “These findings suggest Telomir-Zn may offer a meaningful therapeutic opportunity for veterinary patients. The consistency of anti-tumor activity across both canine and human cell lines is particularly compelling because it positions us to explore efficacy in naturally occurring canine osteosarcoma—a model that could accelerate development for both animals and humans.”

 

These results validate the therapeutic potential of Telomir-Zn in osteosarcoma and support further translational investigation.

 

Osteosarcoma: An Unmet Clinical Need

 

Osteosarcoma is the most common primary bone malignancy in children and young adults. Despite decades of chemotherapy-based treatment, survival rates for metastatic disease remain below 30%, with minimal improvement over three decades. In veterinary medicine, osteosarcoma is similarly devastating in large-breed dogs, accounting for the majority of primary bone tumors.

 

The biological similarities between canine and human osteosarcoma, including genetics, tumor biology, and therapeutic response patterns, make the canine model one of the most clinically predictive disease models available for translational research.

 

 
 

 

Strategic Development Pathway

 

Based on these findings, Telomir is assessing osteosarcoma development in canine models as a potential therapeutic pathway, which could support both veterinary indication development and translational advancement toward human osteosarcoma:

 

Track 1: TNBC in Humans — The company’s TNBC program is advancing toward site initiation and Phase 1/2 patient enrollment under an active IND cleared by the FDA, targeting advanced or metastatic triple-negative breast cancer.
  
Track 2: Osteosarcoma in Dogs — Based on these preclinical findings, Telomir is in conversations with The Ohio State University College of Veterinary Medicine and assessing next steps for a potential in vivo efficacy study in canine osteosarcoma. Such research could accelerate clinical development in canine and human osteosarcoma.

 

While the company’s immediate focus remains advancing TNBC toward site initiation and Phase 1/2 patient enrollment, these preclinical findings position potential osteosarcoma development in canine models as a strategic opportunity. If pursued, such a dual-pathway approach could expand the therapeutic indication profile while advancing our platform.

 

The Iron-Modulation Platform

 

Telomir-Zn targets intracellular iron and copper homeostasis to modulate epigenetic pathways. The mechanism involves disruption of intracellular labile iron pools and inhibition of iron-dependent histone demethylases (KDMs), which reverses cancer-associated epigenetic silencing.

 

The company’s strategic focus is triple-negative breast cancer, where the TNBC program is advancing toward site initiation and Phase 1/2 patient enrollment. The osteosarcoma preclinical findings provide an additional translational opportunity to validate the mechanism in a naturally occurring disease model (canine) while simultaneously advancing the lead TNBC indication.

 

Forward Outlook

 

Erez Aminov, Chairman and CEO of Telomir Pharmaceuticals, said: “This research opens a strategic opportunity to develop Telomir-Zn across multiple oncology indications. Our TNBC program is advancing toward site initiation and Phase 1/2 patient enrollment, and we are assessing next steps for potential osteosarcoma development. If successful with either indication, this multi-pronged approach could establish Telomir-Zn as a platform therapy targeting aggressive malignancies, meaningfully expanding our therapeutic scope.”
