Immune checkpoint inhibitor (ICI) combination therapy offers a new option for treatment of unresectable intrahepatic cholangiocarcinoma (uICC). Aim To compare the effect of different anti‐PD‐1 combination therapies as the first‐line treatments for uICC. Methods This study included 318 patients who received chemotherapy alone (Chemo), anti‐PD‐1 plus chemotherapy (ICI‐chemo), anti‐PD‐1 plus targeted therapy (ICI‐target) or anti‐PD‐1 plus targeted therapy and chemotherapy (ICI‐target‐chemo) as first line for uICC from 22 centres in China. The primary endpoint was progression‐free survival (PFS). Secondary endpoints included overall survival (OS), objective response rate (ORR) and safety. Results Patients with ICI‐chemo (median PFS [mPFS], 6.3 months; HR: 0.61, 95% CI: 0.42–0.88; p = 0.008; median OS [mOS], 10.7 months; HR: 0.61, 95% CI: 0.39–0.94; p = 0.026), ICI‐target (7.2 months; HR: 0.54, 95% CI: 0.36–0.80; p = 0.002; 15.8 months; HR: 0.54, 95% CI: 0.35–0.84; p = 0.006) or ICI‐target‐chemo (6.9 months; HR: 0.65, 95% CI: 0.47–0.90; p = 0.009; 14.4 months; HR: 0.47, 95% CI: 0.31–0.70; p 〈 0.001) achieved better clinical outcomes than those with Chemo (3.8 months; 9.3 months). ICI‐target was not inferior to ICI‐chemo in survival outcomes (HR for PFS: 0.88, 95% CI: 0.55–1.42; p = 0.614; HR for OS: 0.89, 95% CI: 0.51–1.55; p = 0.680). ICI‐target‐chemo yielded similar prognoses as ICI‐chemo (HR for PFS: 1.07, 95% CI: 0.70–1.62; p = 0.764; HR for OS: 0.77, 95% CI: 0.45–1.31; p = 0.328) and ICI‐target (HR for PFS: 1.20, 95% CI: 0.77–1.88; p = 0.413; HR for OS: 0.86, 95% CI: 0.51–1.47; p = 0.583) but resulted in more adverse events ( p 〈 0.001; p = 0.010). Multivariable and propensity score analyses supported these findings. Conclusions Among patients with uICC, ICI‐chemo or ICI‐target provided more survival benefits than Chemo while achieving comparable prognoses and fewer adverse events than ICI‐target‐chemo.
