详细描述
This is a single-arm, exploratory clinical study. Aim to explore the safety and efficacy of Vedicetuzumab combined with an immune checkpoint inhibitor (carrellizumab) and platinum-based first-line treatment for locally advanced/metastatic HER2 overexpression (IHC 2+/3+) esophageal squamous cell carcinoma.

入选标准
- •≥18 years old, male or female;
- •Patients with locally advanced unresectable, recurrent, or metastatic esophageal cancer were confirmed by imaging examination, and esophageal squamous cell carcinoma was confirmed by histopathology.
- •For those who have received radical therapy and (new) adjuvant therapy, the time of first recurrence or disease progression is greater than 6 months after the end of the last treatment;
- •The HER2 immunohistochemical test was 2+ or 3+;
- •According to the solid tumor Efficacy Evaluation Criteria (RECIST), there should be at least one target lesion that has not received local treatment such as radiotherapy (target lesion located in the previous radiotherapy area can also be selected as a target lesion if it is confirmed to have progressed and meets the RECIST criteria);
- •ECOG score: 0~1;
- •Expected survival≥12 weeks;
- •The function of vital organs met the following requirements (no blood components and cell growth factors were used in the first 2 weeks of enrollment):
- •Absolute neutrophil count ≥1.5×109/L Platelet ≥100 × 109/L Hemoglobin ≥90g/L Serum albumin ≥28g/L Bilirubin≤ 1.5 × ULN In the absence of liver metastasis, ALT and AST≤2.5 × ULN; in the presence of liver metastasis, ALT and AST≤5 × ULN Creatinine clearance ≥50ml/min(Cockcroft-Gault); Left ventricular ejection fraction (LVEF) was ≥50% by echocardiography;
- •Fertile female subjects should undergo a urine or serum pregnancy test that proves negative within 72 hours prior to receiving the initial study drug administration and be willing to use an effective method of contraception during the trial period until 3 months after the last dose. For male subjects whose partner is a woman of childbearing age, effective contraception should be used during the trial and within 3 months after the last dose;
- •The subjects voluntarily joined the study, signed informed consent, had good compliance, and cooperated with follow-up.
排除标准
- •Other malignancies have been diagnosed within 3 years prior to the first dose, except for effectively treated basal cell carcinoma of the skin, clinical cell carcinoma of the skin, and/or effectively resected cervical and/or breast cancer in situ;
- •There is central nervous system metastasis treatment within one month after stabilization;
- •Have any active autoimmune disease or a history of autoimmune disease (such as interstitial pneumonia, uveitis, enteritis, hepatitis, hypophysitis, vasculitis, myocarditis, nephritis, hyperthyroidism, hypothyroidism (can be included after normal hormone replacement therapy); Patients with vitiligo or who had complete remission of asthma in childhood and did not require any intervention as adults could be included, but patients with asthma requiring medical intervention with bronchodilators could not be included;
- •suffering from uncontrolled cardiac clinical symptoms or diseases, such as NYHA class II or above heart failure; Unstable angina pectoris; Myocardial infarction within 1 year; Patients with clinically significant supraventricular or ventricular arrhythmias requiring clinical intervention;
- •Active infection or unexplained fever >38.5℃ occurred during screening or before the first administration of the drug (as determined by the investigator, the subject's fever due to the tumor could be enrolled);
- •Known history or evidence of interstitial lung disease or active non-infectious pneumonia;
- •congenital or acquired immune deficiency (such as HIV infection), active hepatitis B (HBV-DNA≥104/L copy number /ml) or hepatitis C (hepatitis C antibody positive and HCV-RNA higher than the lower detection limit of analytical methods);
- •Known allergic reactions, hypersensitivities or contraindications to macromolecular protein preparations, or to platinum or any component used in preparations there of;
- •Subjects requiring systemic therapy with corticosteroids (>10mg/ day efficacy dose of prednisone) or other immunosuppressants within 14 days prior to initial drug use. In the absence of active autoimmune disease, inhaled or topical steroid and adrenocortical hormone replacement at a therapeutic dose of >10mg/ day of prednisone are permitted;
- •Participate in other clinical studies;
- •Have received live vaccine within 4 weeks prior to the first administration of the drug, and are allowed to receive inactivated virus vaccine for seasonal influenza injection, but are not allowed to receive live attenuated influenza vaccine for nasal administration;
- •Pregnant or lactating women;
- •In the investigator's judgment, the subject has other factors that may lead to the forced termination of the study, such as other serious medical conditions (including mental illness) requiring co-treatment, serious abnormalities in laboratory test values, or family or social factors that may affect the subject's safety or the circumstances of the trial data collection.
