What is HERA?

HERA stands for HERceptin® Adjuvant Trial. HERA is co-ordinated by BIG* and F. Hoffmann-La Roche Ltd. This important international study aims to evaluate the effectiveness of adjuvant Herceptin® in HER2-positive patients with primary breast cancer. Approximately 5,100 patients were enrolled from 480 sites in 39 countries.

The first patient was enrolled into the trial in December 2001.

Screening for entry into the HERA study was closed on the 21st May 2004. Patients who have not yet been screened are no longer able to enter the HERA study.

*Additional collaborative partners for the HERA study include: collaborative groups affiliated with BIG, plus non-affiliated collaborative groups, and independent sites.
