AIM: The REACH and REACH-2 trials investigated ramucirumab versus placebo in patients with advanced hepatocellular carcinoma (HCC). Ascites is common in HCC and is associated with poorer outcomes. This exploratory, pooled meta-analysis of patients with baseline α-fetoprotein (AFP) ≥400 ng/ml investigated outcomes by treatment-emergent (TE) ascites in REACH and REACH-2.
METHODS: A pooled meta-analysis of independent patient data for participants (N = 542) with baseline AFP ≥400 ng/ml (stratified by study) from REACH and REACH-2 was carried out. Overall survival (OS) and progression-free survival (PFS) were evaluated by Kaplan-Meier estimator, and OS further assessed by Cox models. The effect of TE ascites on OS was evaluated by multivariate Cox models.
RESULTS: Treatment-emergent ascites developed in 66 patients (20.9%) in the ramucirumab group and 33 patients (14.8%) in the placebo group. When adjusted for treatment duration, the incidence rates per 100 patient-years of any grade TE ascites were 59.1 and 71.9 for the ramucirumab and placebo groups, respectively, and the incidence of grade ≥3 TE ascites were 13.4 and 19.6, respectively. Treatment-emergent ascites was associated with TE hypoalbuminemia (odds ratio 4.9; 95% confidence interval 2.5-9.3), but not TE proteinuria or hypertension. One patient discontinued ramucirumab treatment due to TE ascites. Ramucirumab treatment improved OS and PFS compared with placebo, irrespective of TE ascites.
CONCLUSIONS: When adjusted for treatment duration, the incidence of TE ascites was no higher in patients who received ramucirumab than in those who received placebo. Ramucirumab was well tolerated and provided a survival benefit irrespective of the development of TE ascites.
