PHASE3
Brief Summary
The study is being conducted to evaluate the efficacy, and safety of SHR-A1811 in advanced colorectal cancer subjects.
Eligibility Criteria
Inclusion
- Unresectable locally advanced or distant metastatic RAS/RAF wild-type colorectal cancer diagnosed histologically or cytologically;
- After treatment with oxaliplatin, 5-fluorouracil (such as 5-FU, Capecitabine) , irinotecan (DMMR/MSI-H subjects also need anti-PD-1/PD-L1 antibody treatment failure) ;
- According to the response evaluation criteria for solid tumors (RECIST 1.1) , having at least one measurable lesion, measurable lesions should not have received local treatment such as radiotherapy (lesions located within the previously treated area may also be targeted if progression is confirmed) .
- ECOG physical strength score: 0-1;
- Expected survival was ≥12 weeks;
- 24-hour urine protein ≤1.0 g d) clotting: activated partial thromboplastin time (APTT) and international standard ratio (INR )≤1.5 × ULN (for use of a stable dose of anticoagulant therapy such as LMWH or Warfarin and INR can be screened within the expected range of anticoagulant therapy) ;
- Eligible fertile patients (men and women) must agree to use a highly effective contraceptive method with their partner for at least 7 months during the trial and after the last dose; women of reproductive age must have a negative blood pregnancy test within 7 days before the first use of the study drug;
- The subjects volunteered to join the study, signed the informed consent, good compliance, with follow-up.
Exclusion
- Subjects on systemic therapy with corticosteroid (\> 10 mg daily equivalent of prednisone) or other immunosuppressive agents, except for local inflammation and the prevention of allergy and nausea and vomiting, who had undergone major surgery or severe trauma within 4 weeks prior to the first corticosteroid of the study drug, or who required elective surgery during the trial, who had undergone minor traumatic surgery, such as needle biopsy, within 7 days prior to the first dose of the study drug;
- Previous allergies to monoclonal antibody, formulation components of SHR-A1811 products, and fluorouracil medications;
- Previous antineoplastic therapy toxicities did not revert to a CTCAE v5.0 grade rating of ≤1(except for toxicities that the investigator judged to have no safety risk, such as alopecia, etc.) or the level specified by the enrollment/exclusion criteria;
- Subjects with a history of meningeal metastasis or current meningeal metastasis; active brain metastasis;
- uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated drainage;
- history of immunodeficiency, these included people who tested positive for HIV or who had a fever of \> 38.5 degrees of unknown cause before the first dose (cancer fever, as judged by the researchers, could be enrolled); Severe infection (CTCAE \> Grade 2) occurred within 4 weeks before the first use of the study drug, such as severe pneumonia, bacteremia, infection complications, etc. Baseline chest imaging showed active pulmonary inflammation, active hepatitis B (HBV DNA ≥500 IU/mL) and hepatitis C (HCV-RNA was higher than the lower limit of detection);
- Other malignancies in the past 5 years, not including cured skin basal-cell carcinoma and carcinoma in situ of the cervix;
