A female participant of childbearing potential must have a negative serum pregnancy test within 72 hours before the first administration of study treatment, must not be breastfeeding, and must agree to use a highly effective method of contraception with an annual failure rate of less than 1%, such as an intrauterine device, oral contraceptive, or condom, throughout the study and until 2 months after the last dose of adebrelimab or 6 months after the last dose of chemotherapy, whichever is longer. A male participant with a female partner of childbearing potential must be surgically sterile or agree to use an effective method of contraception throughout the study and until 2 months after the last dose of adebrelimab or 3 months after the last dose of chemotherapy, whichever is longer. Sperm donation is not permitted during the study.\n12. Able and willing to comply with the study procedures and follow-up requirements.\n\nExclusion Criteria:\n\nParticipants meeting any of the following criteria will be excluded:\n\n1. Obvious invasion by the tumor or involved lymph nodes into organs adjacent to the esophageal lesion, including the pleura, pericardium, azygos vein, diaphragm, peritoneum, major arteries, vertebral body, or trachea.\n2. Supraclavicular lymph node metastasis.\n3. Diagnosis of another malignant tumor within 5 years before the first administration of study treatment, except for a malignancy with a low risk of metastasis or death and an expected 5-year survival rate greater than 90%. Participants with adequately treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin, cervical carcinoma in situ, or a similar malignancy may be considered eligible.\n4. Uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated drainage.\n5. Poor nutritional status, defined as a body mass index (BMI) of less than 18.5 kg\u002Fm2. A participant whose nutritional status is corrected through appropriate nutritional support before the initiation of treatment may still be considered eligible following assessment by the principal investigator.\n6. History of an allergic reaction to a monoclonal antibody.\n7. Receipt of any tumor-directed radiotherapy, chemotherapy, or other antitumor medication.\n8. Use of immunosuppressive medication or systemic corticosteroid treatment for an immunosuppressive purpose within 2 weeks before the first administration of study treatment at a dose greater than 10 mg\u002Fday of prednisone or an equivalent dose. In the absence of an active autoimmune disease, inhaled or topical corticosteroids and adrenal corticosteroid replacement at a dose greater than 10 mg\u002Fday of prednisone or an equivalent dose are permitted.\n9.

The study hypothesis is that information from the two scans can identify patients who are unlikely to have a pathologic complete response (pCR), meaning no remaining cancer in the removed esophagus or lymph nodes, and that retlirafusp alfa may improve pathologic response compared with adebrelimab when each is combined with chemotherapy in these patients.\n\nThis study has two stages and plans to enroll 92 adults aged 18 to 75 years with previously untreated, stage II to IVA, resectable thoracic esophageal squamous cell carcinoma.
