The HER signaling pathway plays a role in the formation and growth of numerous cancers, and previous clinical trials of Perjeta (Pertuzumab) in a single agent setting had suggested clinical activity - including stable disease - in heavily pretreated patients with advanced ovarian and breast cancers.
