The Nanomedicine Research Center at the Cedars-Sinai Department of Neurosurgery was established in August 2011. Julia Ljubimova, MD, PhD, leads the nanomedicine research team that includes synthetic chemists, pharmacologists, molecular biologists, radiologists and clinical oncologists.

The main goal of the nanomedicine research team is to engineer and synthesize effective nanomedicines for imaging and treatment of primary and metastatic cancers, including brain gliomas and primary and metastatic (secondary) HER2-positive and triple negative breast and lung cancers, which are incurable with current therapy. These nanodrugs can be intravenously delivered across the blood-brain barrier (BBB) and have been shown to be effective in treating gliomas, as well as breast cancer and brain metastasis from primary lung and breast tumors in mice.

The Nanomedicine Research Center has been awarded $11.5 million by NIH/NCI grants for developing and establishing a novel class of anti-cancer imaging and treatment agents, the latest evolution of molecular drugs designed to slow or stop cancers by blocking them in multiple ways. The ultimate goal is to bring these novel classes of imaging and treatment nanomedicines to the clinical practice.

Compared with conventional chemotherapy, the novel nanodrugs developed at the Cedars-Sinai Nanomedicine Research Center are more effective for treating experimental primary and secondary tumors by increasing the concentration of the anti-cancer drug directly at the tumor site while decreasing general toxicity and immunogenicity. By using the alternative nanodrug delivery mechanisms, scientists can aid in fighting the multidrug resistance that is the hallmark of cancer cells.

The new generation of nanomedicine imaging agents and drugs aim to

The nanodrugs are biodegradable and nontoxic for patients and are able to deliver multiple anti-tumor inhibitors simultaneously directly to cancer cells. In addition, nanodrugs prevent and/or overcome drug resistance and improve the efficacy of treatment, leading to improved quality of cancer patients’ lives. Engineered drugs can be adapted for each cancer patient, with adjustments for individual tumor genome/proteome profiles for treatment of primary tumors and for patients’ tumor progression.

Environmental nano pollution and its influence leading to the development of brain tumors and neurodegenerative disorders are under intensive investigation at the Nanomedicine Research Center.

The Nanomedicine Research Center is a part of the NIH/NCI Alliance for Nanotechnology in Cancer 20102015, which engages the nation’s leading nanomedicine centers in a collaborative effort aimed at accelerating use of nanotechnology to advance cancer diagnosis, treatment and prevention.

Nanomedicine Research Center is multidisciplinary, combining collaborations across a number of departments at Cedars-Sinai, including:

Through these collaborations, we are able to design drugs in the laboratory and test them on animal models.
