简要总结
This study will evaluate the safety and tolerability of BI-CON-02 in patients with HER2-positive metastatic breast cancer, previously treated with trastuzumab The clinical trial protocol for BI-CON-02 prescribes a start dose of 0,3 mg/kg. After the Data and Safety Monitoring Committee evaluates the data of tolerability and safety of BI-CON-02, received during 3 weeks of investigational product therapy (Week 3, Day 1) and approves, extra doses can be used.
Once the safety of investigational product is confirmed, the dose will be increased in the subsequent cohorts. Planned doses - 0,3 mg/kg; 0,6 mg/kg; 1,2 mg/kg; 2,4 mg/kg; 3,6 mg/kg and 4,8 mg/kg.
