Abstract
Breast cancer represents an important problem in public health, being one of the leading causes of death among women. Among the drugs used in the therapy, one of the most employed is paclitaxel, a cytotoxic agent with high potency and efficacy; however, it is associated with several side effects, because of drug and also due to the formulation composition. Recently, the observation that diabetic patients under treatment with metformin had better responses to cancer treatment stimulated investigation on its use in the treatment of this neoplasia, which has been presenting promising results. Cases of breast cancer with overexpression of HER2 receptor are also very aggressive and therapy with the antibody anti-HER2 has been used successfully. Still, this antibody, trastuzumab (Herceptin®), could be used in pharmaceutical technology to target delivery systems to the cancer cells, enabling site-specific drug release. Based on this, the purpose of the present project is to functionalize with trastuzumab previously developed and characterized liposomes containing paclitaxel and metformin. Physical chemical characterization will involve the evaluation of antibody integrity, particle size measurement, zeta potential determination, morphology determination using transmission electronic microscopy. Cellular uptake and localization of the liposomes will be evaluated using confocal microscopy. The safety and efficacy evaluation of immunoliposomes will employ cytotoxicity studies and in vivo therapeutic evaluation, using xenograft animal models (AU)
