drug delivery system

Scientists have developed a new drug delivery system that is capable of crossing the blood-brain barrier to reach and kill cancer cells in the brain.

Following successful preclinical studies, the technology is being evaluated in two phase I clinical trials in patients with malignant glioma and brain metastases.

(Harvard Medical School) Scientists have developed a new self-assembling hydrogel drug delivery system that is biocompatible, efficient at drug release, and easy to tailor.

Importantly, these structures can deliver clinically approved drugs in high concentrations without requiring carriers for the drug or generating toxic components, a problem with hydrogel systems until now.

Chemical engineers have broken the "mucus barrier," engineering the first drug-delivery particles capable of passing through human mucus -- regarded by many as nearly impenetrable -- and carrying medication that could treat a range of diseases.

Those conditions include lung cancer, cervical cancer and cystic fibrosis, the research say.
