Isabelle, I'm in the Phase I-II Herceptin/Vaccine trial, which does allow stable disease if you have been off chemo for 30 days prior to entering the study and be on Herceptin while taking the vaccine. Here's the link from this site, the Research Nurse is Patty Fintak, and her contact information is provided. Good Luck!
