Breast Cancer
Conditions
Brief summary
This is a randomised, double-blind multicenter Phase III study for evaluating the efficacy and safety of pyrotinib in women with early stage high-risk breast cancer after adjuvant trastuzumab. The main purpose of this study is to investigate whether pyrotinib can further reduce the risk of recurrence from previously diagnosed HER-2 positive breast cancer after adjuvant treatment with trastuzumab.
Interventions
pyrotinib 400 mg, orally once daily for one year
placebo 400mg, orally once daily for one year

Eligibility
Inclusion criteria

Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Invasive Disease-free Survival (iDFS) | From randomization until time of event up to 2 years | Invasive disease-free survival time is defined as the time from date of randomization until the first invasive disease recurrence of the following events: invasive ipsilateral breast tumor recurrence, invasive contralateral breast cancer, local/regional invasive recurrence, distant recurrence and death from any cause. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Disease-free Survival (DFS) | From randomization until time of event up to 2 years | Disease-free survival time is defined as the time from date of randomization until the first disease recurrence of the following events: invasive ipsilateral breast tumor recurrence, invasive contralateral breast cancer, local/regional invasive recurrence, non-breast primary invasive cancer, ductal carcinoma in situ(DCIS),or distant recurrence and death from any cause. |
| Overall Survival (OS) | up to 2 years | Overall survival is defined as the time from randomization to death from any cause. |
| Distance Disease-free Survival (DDFS) | distant recurrence From randomization until time of event up to 2 years | Distance Disease-free Survival is defined as the time from date of randomization until the first distant recurrence and death from any cause. |
