Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall response rate (ORR) | From the date of starting pyrotinib to the date of confirmed CR or PR (up to approximately 1 years) | ORR is the percentage of subjects with complete remission (CR) or partial remission (PR) as the best response during the period from the beginning of the treatment to the progression of the disease or the completion of therapy (CR+PR)/Analysis of the total number of people. Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) was used to assess the objective tumor response. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression-Free Survival (PFS) | From the date of starting pyrotinib to the date of first documentation of disease progression or death from any cause (up to approximately 1 year) | PFS is defined as the time from the date of starting maintenance therapy to the date of disease progression or death from any cause, whichever occurs first. |
| Adverse events | From the date of starting pyrotinib to the end of the treatment (up to approximately 1 year) | Adverse events during maintenance therapy will be assessed according to the NCI CTCAE v5.0. |
