Introduction!#!Cabozantinib and ramucirumab are approved for the treatment of adults with hepatocellular carcinoma (HCC) following prior sorafenib treatment; ramucirumab is restricted to use in patients with serum alpha-fetoprotein (AFP) ≥ 400 ng/mL. This matching-adjusted indirect comparison evaluated the efficacy and safety of both drugs after sorafenib in patients with HCC and AFP ≥ 400 ng/mL.!##!Methods!#!Individual patient data (IPD) from the CELESTIAL trial (cabozantinib) and population-level data from the REACH-2 trial (ramucirumab) were used. To align with REACH-2, the CELESTIAL population was limited to patients who received first-line sorafenib only and had baseline serum AFP ≥ 400 ng/mL. The IPD from CELESTIAL were weighted to balance the distribution of 11 effect-modifying baseline characteristics with those of REACH-2. Overall survival (OS; primary endpoint) and progression-free survival (PFS) were compared for the CELESTIAL (matching-adjusted) and REACH-2 populations using weighted Kaplan-Meier (KM) curves and parametric (OS, Weibull; PFS, log-logistic) modeling. Rates of treatment-related adverse events (TRAEs) and TRAE-related discontinuations were also compared.!##!Results!#!After matching and weighting, baseline characteristics were balanced between populations (REACH-2, N = 292; CELESTIAL, effective sample size = 105). Weighted KM estimates for OS (median [95% CI]) were not significantly different between cabozantinib and ramucirumab (10.6 [9.5-17.3] months versus 8.7 [7.3-10.8] months; p = 0.104), but PFS was significantly longer for cabozantinib than for ramucirumab (5.5 [4.6-7.4] months versus 2.8 [2.7-4.1] months; p = 0.016). Parametric modeling results were consistent with the weighted KM analysis. Rates of some grade 3 or 4 TRAEs were lower with ramucirumab than with cabozantinib; however, TRAE-related discontinuation rates were similar (p = 0.271).!##!Conclusion!#!In this MAIC, cabozantinib significantly prolonged median PFS compared with ramucirumab after prior sorafenib treatment in patients with HCC and AFP ≥ 400 ng/mL; rates of some grade 3 or 4 TRAEs were lower with ramucirumab than cabozantinib but related discontinuation rates were not significantly different between treatments.!##!Trial registration!#!Clinical trials.gov identifiers: CELESTIAL trial (NCT01908426) and REACH-2 trial (NCT02435433).
