New Drug for HER2+ Breast Cancers

I stumbled across a post on the Breast Cancer Care forum regarding a new drug called Kadcyla is a new generation of Herceptin used to treat Her2 cancers that have progressed after treatment with Herceptin and Tykerb (Lapatanib). I believe it combines three drugs (1) Herceptin (2) a chemo (3) a chemically modified agent that delivers these two directly into the cancer cell (so no chemo SE's. Have provided a link to article about it for anyone who is interested. http://www.medicalnewstoday.com/articles/256790.php
