Arm Intervention/treatment
Experimental: RC48-ADC

Phase Ib: Patients will receive RC48-ADC 1.5 mg/kg or 2.0mg/kg or 2.5mg/kg intravenously (IV) administered once every 2 weeks.

Phase II: Patients will receive a suitable RC48-ADC dose which was selected according to the Ib phase of the experimental results RC48-ADC via IV administered once every 2 weeks.

Drug: RC48-ADC
Other Name: ADC=Antibody-drug conjugates

Active Comparator: Lapatinib plus capecitabine

Phase II: Active Comparator:Lapatinib+capecitabine Lapatinib repeating dose taken orally every day for 3 weeks as a treatment cycle.

Capecitabine :1000 mg/m2 bid, oral. Days: 1-14 every three weeks.

Drug: Lapatinib plus capecitabine

Primary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: Estimated 2 year ]
    Progression-free survival (PFS) was defined as the time from the first day of study treatment (Day 1) to first documented disease progression or death, whichever occurred first. If a patient did not experience disease progression or die, PFS was censored at the day of the last tumor assessment that a patient was known to be progression free.

Secondary Outcome Measures :
  1. Cmax [ Time Frame: Estimated 2 year ]
    Maximum Observed Plasma Concentration

  2. AUC [ Time Frame: Estimated 2 year ]
    Area Under Curve

  3. Tmax [ Time Frame: Estimated 2 year ]
    Time for Cmax

  4. Overall response Rate (ORR) [ Time Frame: Estimated 2 year ]
    As per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 - to estimate the anti-tumor activity of RC48-ADC.

  5. Clinical Benefit Rate (CBR) [ Time Frame: Estimated 2 year ]
    Clinical Benefit Rate was defined as the percentage of patients with complete remission (CR) partial remission (PR) stable (SD) not less than 4 months.
