1 caNanoLab Overview January 2010 Use and Future Directions

2 Nanotechnology User Scenario (1 of 3) Excerpted from Samira Guccione (Stanford): Sorafenib is a Raf kinase inhibitor that disrupts the key Ras/Raf/MEK/ERK cellular pathway which is up-regulated in renal cell carcinoma, glioblastoma multiforme (GBM) and stomach cancer. The drug has significant side effects and a scientist hypothesizes nanoparticle-assisted targeted delivery of the drug will reduce dosing and side effects. A scientist interested in targeting this drug to GBM does research on possible nanoparticle- delivery systems that have the following properties: biocompatibility sufficiently long intravascular half-life to allow for repeated passage through and interactions with the activated endothelium the ability to have ligands and proteins conjugated on the surface in multivalent configuration to increase the affinity and avidity of interactions with endothelial receptors the ability to have functional groups for high-affinity surface metal chelation or radiolabeling for imaging the ability to encapsulate drugs the capability to have both imaging and therapeutic agents loaded on the same vehicle Furthermore, the scientist looks for information on nanoparticles that could potentially target the GBM. In Vivo Characterization Composition

3 Nanotechnology User Scenario (2 of 3) Integrin-targeted nanoparticles are identified. Synthesis involves UV cross linking an avb3-integrin-targeting ligand attached to a lipid, a diacetylene phospholipid and a cationic lipid. These are sonicated to form polymerized vesicles and the avb3- NP can serve as a scaffold for the attachment of therapeutic agents for imaging and therapy. The physical characteristics have been determined including size, zeta potential, IC50 in a cell adhesion assay, and the effect of multivalency IC50. Selectivity was also demonstrated in a receptor binding assay and it is not rapidly cleared from the target tissue. Previous studies have shown this particle to be highly stable, have no toxicity and to specifically target tumor associated vasculature in GBM when conjugated to GFP. Furthermore the particle has been used as an imaging agent when conjugated with Gd3+ or Indium11+. The avb3-NP-Sorafenib is synthesized. Sorafenib absorption characteristics are available and the concentration of the drug in the system is determined via spectroscopy methods. Other physical properties are characterized. Composition Physical Characterization In Vitro Characterization Composition

4 Nanotechnology User Scenario (3 of 3) The scientist investigates what data sets are available on in vivo use of the drug. A breast cancer xenograph subcutaneous model is found and cell lines from this system are also available. However toxicity data for the drug in animal models are not publicly available. The scientist contacts the drug manufacturer and begins in vitro testing. PK/PD in vitro tests, including drug uptake, toxicity and effectiveness, are performed in the model system cell lines, related and control cell lines by comparing the effects of drug alone, nanoparticle alone, and the combination. Next is in vivo testing with three established animal tumor models. The drug alone, nanoparticle alone, and the combination are administered and tumor size (and other parameters) is monitored. Finally efficacy, dosing, and side effects of the current dosing protocol are compared with targeted nanoparticle delivery of Sorafenib. In Vitro, In Vivo Characterization In Vivo Characterization
