Although first-line immunochemotherapy has improved prognosis for patients with advanced esophageal squamous cell carcinoma(ESCC),more effective strategies still require further investigation.This multi-center,phase Ⅱ study(ClinicalTrials.gov NCT05013697)assessed the feasibility of benmelstobart(a novel PD-L1 inhibitor)plus anlotinib(multitargeted TKI)and chemotherapy in advanced or metastatic/recurrent ESCC.Eligible patients received 4-6 cycles(21-day)of benmelstobart(1200 mg),anlotinib(10 mg)plus paclitaxel(135 mg/m2)/cisplatin(60-75 mg/m2),then maintained with benmelstobart and anlotinib.Primary endpoint was progression-free survival(PFS)assessed according to RECIST v1.1.Secondary endpoints were tumor response,overall survival(OS),and safety assessed by adverse events(AEs).From September 2021 to November 2023,50 patients were enrolled and received study treatment.With median follow-up of 23.7 months as of April 1,2024,median PFS was 14.9 months(95％CI,11.4-not estimable[NE])and the 1-year PFS was 58.5％(95％CI,41.9％-71.9％).Among 50 patients,confirmed objective response rate was 72.0％and disease control rate was 84.0％.Median duration of response of 36 responders was 16.2 months(95％CI,10.2-NE).At the cutoff date,31 patients remained alive;median OS was not reached(95％CI,13.2 months-NE)with 1-year OS of 74.8％(95％Cl,59.8％-84.8％).Forty-six(92.0％)patients reported treatment-related AEs,with 37(74.0％)were grade ≥3.Overall,benmelstobart plus anlotinib and chemotherapy showed promising efficacy and acceptable toxicity in advanced or metastatic/recurrent ESCC.
