Summary

This multi-center, open label Phase II clinical study is performed in patients with relapsed and metastatic esophageal squamous cell carcinoma progressed on prior PD-1/L1 antibody with or without chemotherapy. This study is investigating the safety and efficacy of SI-B001 at optimal combination dose with irinotecan in patients.

Inclusion Criteria

•1. Voluntarily sign the informed consent and follow the requirements of the protocol;
•2. Male or female, age: ≥18 years and ≤75 years;
•3. Expected survival time ≥3 months;
•4. Locally advanced esophageal squamous cell carcinoma confirmed histologically or pathologically as recurrent or metastatic or without indications of radical local treatment;
•5. Patients who failed or were intolerant to first-line anti-PD-1 (L1) monoclonal antibody plus platinum-based chemotherapy
•6. Agree to provide archived tumor tissue specimens of primary or metastatic lesion (4 surgical specimens (thickness 5μm) without staining section (anti-removal);6 unstained sections (anti-removal) surgical specimens (thickness 10μm) or fresh tissue samples, if the patient cannot provide, can be included after the investigator's judgment;
•7. There must be at least one measurable lesion conforming to the RECIST V1.1 definition. Tumor lesion located in the area of previous radiotherapy or other local and regional treatment sites is generally not a measurable lesion unless there is definite progression of the lesion or the lesion persists three months after radiotherapy;
•8. Physical fitness ECOG score of 0 or 1;
•9. Toxicity from previous antitumor therapy has returned to ≤1 as defined by NCI-CTCAE V5.0 (except for toxicity that the investigators determined to be of no safety risk, such as hair loss, grade 2 peripheral neurotoxicity, and stabilized hypothyroidism after hormone replacement therapy);
•10. Organ function levels must meet the following requirements and meet the following standards:

•2. Patients with esophageal fistula;
•3. Received an unmarketed clinical investigational drug or treatment within 4 weeks prior to initial use of the investigational drug;
