Официальное название

MRI Guided Personal Chemoradiotherapy and Immunotherapy for Limited Advanced Esophageal Squamous Caicinoma: A Prospective, Multicenter, Single Arm, Phase II Study (FUTURE-3)

Обзор

FUTURE-3 was a prospective, multicenter, single-arm phase II study designed to explore the efficacy and safety of MRI-guided individualized chemoradiotherapy for locally advanced esophageal squamous cell carcinoma. The primary endpoint was one-year progression-free survival rate.

Подробное описание

In this study, patients will receive two cycles of TPF chemotherapy plus adeberib immunotherapy induction, followed by concurrent chemoradiotherapy. One month after the completion of radiotherapy, adebrelimab immunotherapy will be initiated for two years for maintenance. Based on the results of enhanced MRI, the regimen will be adjusted three times: ① After one chemoradiotherapy induction cycle, if the tumor shrinkage is \<20%, the TPF regimen will be replaced with the FLOT regimen; ② After the completion of radiotherapy, if MRI shows significant residual tumor, CRP \<10 ng/L, and no grade II or higher adverse reactions, maintenance immunotherapy will be initiated immediately; ③ One month after radiotherapy, if MRI shows significant residual tumor, capecitabine metrotherapy will be added, and the radiotherapy dose for residual lesions will be increased.

• Locally advanced stage, unresectable or refusing surgery, and stage IV with only extra-regional lymph node metastasis;
• Tolerance of contrast-enhanced MRI;
• Expected survival > 3 months;
• Adequate organ function; subjects must meet the following laboratory criteria:

• Absolute neutrophil count (ANC) ≥ 1.5 x 10⁹/L;
• Platelet count ≥ 100 × 10⁹/L.
• Hemoglobin > 9 g/dL;
• Total bilirubin ≤ 1.5 × Upper Limit of Normal (ULN);
• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN;
• Serum creatinine ≤ 1.5 × ULN and creatinine clearance (calculated using the Cockcroft-Gault formula) ≥ 60 ml/min;
• Good coagulation function, defined as International Normalized Ratio (INR) or Prothrombin Time (PT) ≤ 1.5 times ULN;
• Normal thyroid function, defined as TSH within the normal range. If baseline TSH is outside the normal range, subjects with normal total T3 (or FT3) and FT4 may also be enrolled;
• Cardiac enzyme levels are within the normal range (simple laboratory abnormalities deemed clinically insignificant by the investigator may also be enrolled);
• For female subjects of reproductive age, a urine or serum pregnancy test should be performed within 3 days prior to the first administration of the study drug (day 1 of cycle 1), and the result should be negative. If the urine pregnancy test result cannot be confirmed as negative, a blood pregnancy test is required.

• If there is a risk of pregnancy, all subjects (regardless of gender) must use contraception with an annual failure rate of less than 1% throughout the treatment period until 120 days after the last administration of the study drug (or 180 days after the last administration of chemotherapy).
