Registration Number
NCT00545688
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This 4 arm study will evaluate the efficacy and safety of 4 neoadjuvant treatment regimens in female patients with locally advanced, inflammatory or early stage HER2 positive breast cancer. Before surgery, patients will be randomized to one of 4 treatment arms, to receive 4 cycles of a)Herceptin + docetaxel b)Herceptin + docetaxel + pertuzumab c)Herceptin + pertuzumab or 4)pertuzumab + docetaxel. Pertuzumab will be administered at a loading dose of 840mg iv, then 420mg iv 3-weekly, Herceptin at a loading dose of 8mg/kg iv then 6mg/kg 3-weekly, and docetaxel at a dose of 75mg/m2 escalating to 100mg/m2 3-weekly. During the entire pre- and post-surgery period all patients will receive adequate chemotherapy as per standard of care, as well as any surgery and/or radiotherapy as required. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

pCR was defined as an absence of invasive neoplastic cells at microscopic examination of the tumor remnants after surgery following primary systemic therapy. Participants were classified as Estrogen and/or Progesterone positive (+ve), Estrogen and/or Progesterone negative (-ve) or receptor status unknown. Participants with invalid/missing pCR assessments were defined as non-responders.

Percentage of Participants Achieving pCR by Lymph Node StatusApproximately 4 months from randomization following surgery or early withdrawal, whichever occurred first (Surgery was performed within 2 weeks after Cycle 4)

pCR was defined as an absence of invasive neoplastic cells at microscopic examination of the tumor remnants after surgery following primary systemic therapy.

Percentage of Participants Who Were Progression Free and Disease FreeRandomization up to a maximum of 329 weeks

Disease-free survival (DFS) was defined as the time from first date of no disease to first documentation of PD or death. Participants without progression after surgery were considered Disease Free. Any evidence of contralateral disease in-situ was not considered as PD. Participants who were withdrawn from the study without documented progression and for whom evaluations were made, were censored at date of last assessment when participant was known to be disease-free. Progression-free survival (PFS) was defined as time from date of randomization to first documentation of PD or death. Any evidence of contralateral disease in-situ was not considered as PD. Participants who were withdrawn from study without documented progression and for whom evaluations were made, were censored at date of last assessment when the participant was known to be free from progressive disease. Participants without post baseline assessments but known to be alive were censored at the time of randomization.

Progression Free and Disease Free SurvivalRandomization up to a maximum of 329 weeks

DFS was defined as the time from the first date of no disease (date of surgery) to the first documentation of PD or death. Participants without progression after surgery were considered Disease Free. Any evidence of contralateral disease in-situ was not considered as PD. PFS was defined as the time from the date of randomization to the first documentation of PD or death. Any evidence of contralateral disease in-situ was not considered as PD. DFS and PFS were determined using Kaplan-Meier estimates.
