Real World Study on the Efficacy and Safety of Anti-HER2 Therapy
- Conditions
- HER2-positive Breast CancerBreast Neoplasms
- Registration Number
- NCT05367739
- Lead Sponsor
- Hunan Cancer Hospital
- Brief Summary
Anti HER2 therapy can improve the survival of HER2 positive patients and reduce mortality. The aim of the open-label, real-world study is to assess efficacy and safety of Anti-HER2 treatment drugs.
- Detailed Description
About 30% of breast cancer is human epidermal growth factor receptor-2 (HER2) amplification or overexpression (i.e. HER2 positive). HER2 positive breast cancer is one of the indicators of poor prognosis because of its high risk of invasion and metastasis. Anti HER2 therapy can improve the survival of HER2 positive patients and reduce mortality. The aim of the open-label, real-world study is to assess efficacy and safety of Anti-HER2 treatment drugs including antibody drugs such as trastuzumab and pertuzumab, small-molecule tyrosine kinase inhibitors (TKIs) such as lapatinib, neratinib, and pyrotinib, and antibody-drug conjugates such as trastuzumab deruxtecan (DS-8201) and trastuzumab emtansine (T-DM1).

- Primary Outcome Measures
Name Time Method Objective Response Rate (ORR) From date of randomization until the date at the end of the second treatment cycle (42 days) The total rate of CR+PR after the completion of two cycles of treatment.
Progression-Free Survival (PFS) From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months The survival time from the date of recruitment to the date of the first documented progression or date of death.
Adverse Events From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months All adverse events \[including adverse events (AE / SAE) and ADR (adverse drug reactions)\] will be collected when known. The classification of adverse reactions shall refer to CTCAE5.0 in case of adverse events / reactions. In case of serious adverse events, the investigators must immediately take necessary treatment measures to protect the safety of subjects. All adverse events / reactions should be tracked and observed. If the adverse events have not recovered, the investigator shall continue to give necessary treatment, report and record, and deal with special cases according to the management opinions of relevant departments.
