Inclusion Criteria
- Able and willing to provide a written informed consent. Have good compliance and cooperated with follow-up visits.

- ≥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.
- 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):
- Left ventricular ejection fraction (LVEF) ≥ 50% at baseline within 28 days prior to initial administration.
- 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
- Subjects with untreated or known active CNS metastasis. Subjects with a history of meningeal metastasis or known active meningeal metastasis.

- 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).
- Toxicity and/or complications of previous interventions were not recovered to NCI-CTCAE ≤ grade 1 or didn't meet this inclusion criteria and exclusion criteria. If investigator determines that the toxicity and/or complications are NCI-CTCAE ≤ grade 2 and there is no safety risk, this subject can be enrolled. For example, patients with type 1 diabetes or hypothyroidism who have been treated with immune checkpoint inhibitors and are stable after hormone replacement therapy.
- Have a history of (non-infectious) interstitial lung disease (ILD). Suspected ILD. Other moderate and severe lung diseases that may interfere the detection or management of drug-related pulmonary toxicity and severely affect respiratory function within 3 months before the first test drug administration. Any autoimmune disease, connective tissue disease, or inflammatory disease with lung involvement.

- Patients with moderate and severe ascites of clinical symptoms Refractory or moderate to severe pleural effusion or pericardial effusion.
- Patients with intestinal obstruction within 6 months prior to the first test drug administration or presence of signs and symptoms of intestinal obstruction (patients can be enrolled if surgical treatment had been performed and the obstruction had been completely resolved).
- Have clinically significant cardiovascular disease.
- Previous or combined with other malignancies except those have achieved complete remission and do not require or are not expected to require other treatment during the study period within at least 5 years prior to screening, including basal cell carcinoma of the skin, superficial bladder cancer, squamous cell carcinoma of the skin, cervical carcinoma in situ, local prostate cancer, ductal carcinoma in situ after radical surgery, etc (hormone therapy for non-metastatic prostate cancer or breast cancer is allowed) .
- Serious infections within 28 days prior to the first test drug administration. Active infections that had received therapeutic intravenous antibiotics within 2 weeks prior to the first test drug administration. Prophylactic antibiotic therapy can be enrolled.
- Active hepatitis B or active hepatitis C infection. Active hepatitis B is defined as hepatitis B surface antigen (HBsAg) positive and HBV-DNA ≥10000 copies/ml [2000 IU/ml] during screening. Active hepatitis C is defined as hepatitis C virus antibody positive and HCV-RNA positive during screening. Patients with active pulmonary tuberculosis infection within 1 year before enrolment, or with a history of active pulmonary tuberculosis infection but without regular treatment more than 1 year before enrolment. Has known immunodeficiency disorders, including human immunodeficiency virus (HIV) infection, etc. Received attenuated live vaccines within 28 days of initial administration.
