Revolutionary Cancer Treatment: New Platform Delivers Two Drugs Simultaneously to Tumors
Scientists from Israel, Italy, Portugal, and the Netherlands have developed an innovative technology that allows the simultaneous administration of two different drugs to tumor areas in the patient’s body, as announced by Tel Aviv University via a press release reported by the Xinhua news agency, according to Agerpres.
Cancer treatments often involve combining drugs to enhance therapeutic effectiveness. However, differences in drug properties, such as degradation rates, circulation times, and tumor penetration levels, can hinder their simultaneous arrival in tumor areas, limiting their combined efficacy.
To maximize effectiveness and minimize toxicity, researchers have created a new platform that transports two drugs simultaneously and selectively to the tumor site without affecting healthy organs. This method, described in the journal Science Advances, uses biodegradable polymeric nanoparticles to encapsulate pairs of drugs designed for treating certain types of cancer, including skin and breast cancer.
The platform was tested using two drug pairs for skin and breast cancer on 3D cancer cell models and animal models. Results showed that the nanoparticles accumulated selectively in primary tumors without affecting healthy tissues and successfully penetrated the blood-brain barrier, precisely reaching cerebral metastases.
Simultaneous administration of both drugs proved much more efficient than separate administration, significantly reducing tumor size and improving the lifespan of laboratory mice. Researchers concluded that this versatile platform can transport various drug pairs that enhance each other’s effects, improving treatment for primary tumors and metastases expressing the P-selectin protein.
This groundbreaking technology offers new hope in the fight against cancer, paving the way for more effective and targeted treatments. As clinical trials progress, patients and healthcare providers can look forward to potential advancements in cancer care.
