Eligibility
Inclusion criteria
1. Able and willing to provide a written informed consent. Have good compliance and cooperated with follow-up visits. 2. Subjects are older than or equal to 18 years old and younger than or equal to 75 years old on the day of signing the informed consent. Male or female. 3. ECOG score 0-1. 4. Life expectancy is at least 12 weeks. 5. Histologically or cytologically confirmed metastatic or advanced unresectable HER2-expression or Her-2 functional mutations solid tumors. 6. Provide ≥ 6(or ≥8)sections of formalin-fixed, paraffin-embedded tumor tissue blocks or unstained tumor specimen sections. Sections should be archived within 1 year before the first study treatment or freshly obtained (freshly obtained is preferred). 7. ≥1 Measurable lesions, according to the Response Evaluation Criteria for Solid Tumors (RECIST) version 1.1. The dose escalation phase allows for the absence of measurable lesions. 8. Organ function met criteria within 7 days prior to initial administration (No blood component or cell growth factor was used within 14 days before the initial administration): 9. Left ventricular ejection fraction (LVEF) ≥ 50% at baseline within 28 days prior to initial administration. 10. Males and women of childbearing age must use reliable contraception from the written informed consent to 7 months after last drug administration (SHR-A1811) or 8 weeks after last drug administration (Pyrotinib) or 6 months after last drug administration (BP102 or Oxaliplatin or Calcium levonofolinate or fluorouracil), the latest time should be taken as final. Women of childbearing age must have had a pregnancy test (serum or urine) with negative results within 7 days prior to initial administration and must not in lactation period.
Exclusion criteria
1. Subjects with untreated or known active CNS metastasis. Subjects with a history of meningeal metastasis or known active meningeal metastasis. 2. Have a history of antibody drug conjugate with following characteristics: topoisomerase I inhibitors, including Enhertu (DS-8201a), U3-1402, etc. Part A: Have a history of Her-2 targeted tyrosine-kinase inhibitor (TKI). 3. Palliative radiotherapy within 14 days prior to initial administration. Subjects who had received systemic anti-tumor therapy within 4 weeks prior to initial administration will not permitted. The interval between the end of small-molecule targeted drugs administration and initial test drug administration must be ≥ 5 half-lives or 7 days (take the longer time). The interval between the end of Chinese patent anti-tumor drug administration and initial test drug administration must be ≥ 2 weeks. Participating in another clinical study of other drugs. The interval between the previous clinical study drug use and this study initial administration is less than 4 weeks or 5 half-lives of previous clinical study drug (take the shorter time). 4. Toxicity and/or complications of previous interventions were not recovered to NCI-CTCAE ≤ grade 1 or didn't meet this inclusion criteria and
