Nanoparticle complexes of albumin, paclitaxel, and anti-VEGF antibody for treatment of cancer
This document provides materials related to treating cancer (e.g., skin cancer). For example, materials relating to the use of a composition containing albumin-containing nanoparticle/antibody complexes (e.g., albumin-bound paclitaxel/anti-VEGF polypeptide antibody complexes) to treat cancer (e.g., skin cancer) are provided).
1. An antibody-albumin nanoparticle complex comprising albumin, a bevacizumab antibody, and paclitaxel, wherein the nanoparticle complex has been pre-formed in vitro by mixing an aqueous albumin-paclitaxel nanoparticle with the antibody under conditions to form the nanoparticle complex, such that the nanoparticle complex has VEGF binding specificity, and wherein the complex has a diameter of between 0.1 μm and 1 μm.
2. The antibody-albumin nanoparticle complex of claim 1 , said complex having a diameter of between 0.1 μm and about 0.9 μm.
3. The antibody-albumin nanoparticle complex of claim 1 , said complex having a diameter of between about 0.1 μm and 0.3 μm.
