E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the antiproliferative and/or pro-apoptotic activity of denosumab in early breast cancer. If the Hypothesis of this study is proven right it will substantiate and provide rationale to the development of denosumab as an ant-cancer drug in breast cancer. |
Demostrar la actividad antiproliferativa y/o proapoptótica del denosumab en el cáncer de mama precoz. Si se demuestra la hipótesis de este estudio se podría sustanciar el inicio del desarrollo de denosumab como tratamiento antitumoral en cáncer de mama |
|
E.2.2 | Secondary objectives of the trial |
• To correlate the antiproliferative/pro-apoptotic activity of denosumab with the expression of RANK, RANKL (protein expression) and RANK/RANKL modified ratio (mRNA). • To characterize the differential antiproliferative/pro-apoptotic activity of denosumab among the different phenotypes of breast cancers. • To characterize the differential antiproliferative/pro-apoptotic activity of denosumab among pre and post menopausal patients, and menstrual cycle in preneoplasic patients |
• Correlacionar la actividad antiproliferativa/ proapoptótica del denosumab con la expresión de RANK, RANKL (expresión protéica) y RANK/RANKL ratio modificado (mRNA). • Caracterizar las diferencias en la actividad antiproliferativa/proapoptótica del denosumab entre los dife-rentes fenotipos del cáncer de mama. • Caracterizar las diferencias en la actividad antiproliferativa/proapoptótica del denosumab entre pacientes pre y postmenopáusicas y en el ciclo menstrual en las pacientes premenopaúsicas. |
