In a stunning progress for pediatric oncology, a medicine initially tested on dogs suffering from bone cancer is demonstrating remarkable potential as a future treatment for children battling the same aggressive disease. This advancement highlights the growing meaning of comparative oncology, a field that recognizes the shared biology of cancer across species.
From Veterinary clinic to Pediatric Ward: A Cancer Treatment Revolution
The unlikely journey of this cancer treatment began with observations of osteosarcoma, a rare and devastating bone tumor, in dogs. Surprisingly, dogs develop cancers with similar biological mechanisms to humans, making them invaluable models for research. Osteosarcoma, in particular, affects both children and large dog breeds.
Each year, hundreds of children and thousands of dogs in France are diagnosed with osteosarcoma. Conventional treatments involve aggressive surgery, frequently amputation, followed by chemotherapy. Sadly, the prognosis remains bleak if the cancer returns or spreads, especially to the lungs.
Os Therapies, an American company, is pioneering a new approach with Ost-Her2, an immunotherapy designed to target the HER2 protein, a well-known target in oncology.
Harnessing Bacteria: A Novel Approach to Cancer Immunotherapy
HER2 (Human Epidermal Growth Factor Receptor 2) is overexpressed in various cancers, including breast, esophageal, lung, pancreatic, and osteosarcoma. Ost-Her2 employs genetically modified *Listeria monocytogenes* bacteria to deliver therapeutic DNA.
When injected, the weakened *Listeria* triggers a robust immune response, teaching the body to recognize and destroy HER2-expressing tumor cells. This innovative “vaccine” approach offers a personalized strategy to combat cancer.
Landmark Canine Trial Paves the Way for human Studies
Os Therapies initially tested Ost-Her2 on dogs afflicted with osteosarcoma. The results, published in *Molecular Therapy,* were truly impressive:
- Tumor growth slowed significantly.
- Metastases were reduced.
- Survival rates increased.
- Amputation was avoided or delayed in some cases.
These encouraging outcomes led to the creation of Animal health Os, a veterinary subsidiary focused on marketing the treatment for dogs. More importantly, the canine data directly informed clinical trials in children, exemplifying the power of comparative oncology.
Human Clinical Trial Shows Promising Results
In january 2025, Os Therapies released the results of its Phase 2B clinical trial involving adolescents and young adults (ages 12-39) with surgically treated, metastasized osteosarcoma. The findings revealed:
- A statistically meaningful improvement in recurrence-free survival at 12 months.
- A notable increase in overall survival at one and two years.
- Minimal serious side effects.
Researchers beleive Ost-Her2 has the potential to transform the management of this challenging cancer, for which no approved treatment currently exists for metastatic relapse. The Food and Drug Administration (FDA) has granted the treatment several expedited designations, including Fast Track, Orphan Drug, and Rare Pediatric Disease Designation.
A request for marketing authorization in the United States is expected by the end of 2025.
One Health: A Symbiotic Approach to medicine
This project embodies the “One Health” concept, emphasizing the interconnectedness of human and animal health.By studying cancer in dogs, researchers have accelerated the development of a promising pediatric drug.
Did You Know? The “One Health” approach extends beyond cancer, encompassing research into infectious diseases, environmental health, and food safety.
Future Applications: Expanding the Scope of Ost-Her2
The Ost-Her2 story may extend beyond osteosarcoma. Os Therapies’ targeted immunotherapy platform, utilizing *Listeria*, could possibly target other HER2-expressing solid tumors. If approved, this veterinary-derived treatment could become one of the first human cancer drugs successfully tested in dogs first.
What other cancers could benefit from this comparative oncology approach?
Comparative oncology: Key Facts
| Aspect | Description |
|---|---|
| Definition | Study of naturally occurring cancers in different species to benefit both humans and animals. |
| Model Species | Dogs are frequently enough used due to similar cancer development as humans. |
| Benefits | accelerated drug development, reduced costs, and improved treatment outcomes. |
| Challenges | Funding, regulatory hurdles, and data sharing. |
The Evergreen Potential of Comparative Oncology
Comparative oncology holds immense promise for the future of cancer research and treatment. By leveraging the natural development of cancer in animals, researchers can gain valuable insights into the disease’s biology, identify new therapeutic targets, and accelerate the development of more effective treatments for both humans and animals.
The “One Health” approach, which emphasizes the interconnectedness of human and animal health, is increasingly recognized as a critical framework for addressing complex health challenges like cancer. As research in comparative oncology continues to advance, we can expect to see even more innovative treatments emerge that benefit both people and their beloved pets.
Pro Tip: Support research initiatives that promote comparative oncology and the “One Health” approach to contribute to a healthier future for all.
Frequently Asked Questions About Osteosarcoma and Comparative Oncology
- What is Osteosarcoma?
- Osteosarcoma is a rare and aggressive bone cancer that affects both children and large breed dogs.
- How is Osteosarcoma Typically Treated?
- Traditional treatment involves surgery (often amputation) followed by chemotherapy.
- What is Comparative Oncology?
- Comparative oncology is the study of naturally occurring cancers in animals to benefit both veterinary and human medicine.
- Why are Dogs Significant in Cancer Research?
- Dogs naturally develop cancers with similar biological mechanisms to humans, making them excellent research models.
- What is Ost-Her2?
- Ost-Her2 is an immunotherapy that targets the HER2 protein, which is overexpressed in several types of cancer, including osteosarcoma.
- How Does Ost-Her2 Work?
- Ost-Her2 uses genetically modified *Listeria* bacteria to stimulate the immune system to target and destroy cancer cells.
- What are the Potential Benefits of Ost-Her2?
- Ost-Her2 has shown promise in slowing tumor growth, reducing metastases, and extending survival in both dogs and humans.
