Telomir-Zn Shows Growth Inhibition in Human and Canine Osteosarcoma Models

Telomir Pharmaceuticals (NASDAQ: TELO) has announced new research findings from The Ohio State University College of Veterinary Medicine showing that its lead compound, Telomir-Zn, produced growth inhibition across human and canine osteosarcoma cell-line models at similar low drug concentrations. The study, led by Shay Bracha, DVM, MS, DACVIM (Oncology), evaluated Telomir-Zn in one human and two canine osteosarcoma models. The results support further translational investigation and a potential development pathway using naturally occurring canine osteosarcoma, a disease that shares many biological similarities with human osteosarcoma.

Osteosarcoma is a rare but aggressive bone cancer that primarily affects children and young adults in humans, and large-breed dogs in veterinary medicine. Current treatment options often involve surgery and chemotherapy, but survival rates for metastatic disease remain poor. The fact that Telomir-Zn demonstrated similar growth inhibition across species at low concentrations suggests a conserved mechanism of action that could be exploited for therapeutic benefit in both populations.

Telomir is in discussions with The Ohio State University College of Veterinary Medicine and assessing next steps for a potential in vivo efficacy study in canine osteosarcoma. Such a study could support both veterinary development and translational advancement toward human osteosarcoma. The company said its immediate focus remains its triple-negative breast cancer program, which is advancing toward site initiation and Phase 1/2 patient enrollment under an active FDA-cleared Investigational New Drug (IND) application for advanced or metastatic TNBC.

The news is significant for several reasons. First, it highlights the potential of Telomir-Zn as a multi-indication asset, with activity in osteosarcoma adding to its ongoing development in breast cancer. Second, it underscores the value of comparative oncology, where naturally occurring cancers in pets can serve as models for human disease, potentially accelerating drug development timelines. Third, it positions Telomir to pursue a dual-market strategy, addressing unmet needs in both veterinary and human oncology.
