A new study has revealed that metixene, an antiparkinsonian drug, has shown remarkable potential as a novel treatment for metastatic breast cancer and brain metastases, providing hope for patients facing this devastating disease. The study was conducted by a team of researchers led by Dr. Jawad Fares at Northwestern University and was published in the Journal of Clinical Investigation.
Metastatic brain cancer, particularly in the context of breast cancer, represents a significant challenge in the field of oncology, with limited therapeutic options and poor clinical outcomes. However, this study has identified metixene as a potential game-changer in the fight against this formidable disease.
In a comprehensive investigation, the research team screened a library of 320 central nervous system small-molecule inhibitors known to be blood-brain barrier permeable and approved by the U.S. Food and Drug Administration. Metixene emerged as a standout candidate, demonstrating the ability to
reduce cancer cell viability and induce cancer cell death in various metastatic breast cancer subtypes.
Key findings of the study include:
These promising results open up new possibilities for the treatment of metastatic brain cancer.
Furthermore, metixene's reported minimal side effects in humans make it a strong candidate for clinical translation, offering a glimmer of hope for patients worldwide.
“The study highlights the potential clinical significance of metixene as a promising therapeutic agent for the treatment of metastatic cancer and brain metastases. We showed its effects against all subtypes of breast cancer, in addition to lung cancer and melanoma. The drug was noted for having minimal reported side effects in humans, which makes it a strong candidate for consideration in clinical translation, i.e., further investigation and potential use in human clinical trials,” Fares said.
