About

This is a single-arm, open, exploratory clinical study to evaluate the efficacy and safety of camrelizumab combined with chemotherapy for adjuvant treatment of nodal positive thoracic esophageal squamous cell carcinoma.

Full description

Treatment with carrilizumab combined with chemotherapy was planned for 4 to 6 cycles, after which carrilizumab monotherapy was maintained until disease progression, unacceptable toxicity, or patient withdrawal.

vial card Rayleigh bead sheet resistance: intravenous drip, fixed dose of 200 mg, with 30 minutes to an intravenous drip

(The overall infusion time including the flushing time shall be no less than 20 minutes, no longer than 60 minutes), Day 1, every repeat once every 2 weeks.

paclitaxel: 150 mg/m2, intravenous drip for 30 minutes, 1 day, every 14 days for a cycle.

cisplatin: 50 mg/m2, 2 days, every 14 days for a cycle.

A total of 4 to 6 cycles, after carrilizumab maintenance treatment for one year.

Enrollment: 23 estimated patients

Sex: All

Ages: 18 to 70 years old

• Patients with esophageal squamous cell carcinoma after R1 or R2 resection;
• The subject has had or co-had other malignancies (except cured basal cell carcinoma of the skin and cervical carcinoma in situ);
• Patients who had received carrilizumab or other PD-1/PD-L1 treatment in the past could not be enrolled; The subject is known to have a prior allergy to macromolecular protein preparations, or is known to be allergic to any carrilizumab, purple or platinum components;
• Subject has any active autoimmune disease or history of autoimmune disease (such as the following, but not limited to: autoimmune hepatitis interstitial pneumonia, uveitis, enteritis, hepatitis, pituitaritis, vasculitis, nephritis, hyperthyroidism, hypothyroidism; Subjects with purpura or complete remission of childhood asthma without any intervention as adults could be included; Patients with asthma requiring medical intervention with bronchodilators were not included);
• Subjects who were taking immunosuppressant or systemic or absorbable topical hormone therapy for immunosuppressive purposes (dose >10mg/ day prednisone or other therapeutic hormone) and continued to use it within 2 weeks prior to enrollment;

• The researcher considers that the subjects should be excluded from the study. For example, the researcher judges that the subjects have other factors that may cause the study to be terminated, such as other serious diseases (including mental illness). Concomitant treatment is required, there are serious laboratory abnormalities associated with family or social factors that may affect the safety of the subject or the collection of data and samples.
