Combination of CRAFITY score with Alpha-fetoprotein response predicts a favorable outcome of atezolizumab plus bevacizumab for unresectable hepatocellular carcinoma.

ABSTRACT: Immune checkpoint inhibitors (ICIs) with atezolizumab plus bevacizumab are promising agents for unresectable hepatocellular carcinoma (HCC). We tried to guide the treatment based on recent developed CRAFITY score combining with on-treatment AFP response. Eighty-nine patients who received atezolizumab plus bevacizumab regardless of as a first-line therapy or not for unresectable HCC were enrolled for analyses. Radiologic evaluation was based on modified Response Evaluation Criteria in Solid Tumors (mRECIST). The objective response rate (ORR) and disease control rate (DCR) were 25.0% and 65.5%, respectively. Multivariate analysis showed that low CRAFITY score (AFP<100 ng/ml or CRP<10 mg/l) and satisfactory AFP response at 6 weeks (≥75% decrease or ≤10% increase from baseline) were independent factors determining good overall survival (OS) (hazard ratio [HR]=0.143, P=0.002 & HR=0.337, P=0.031), progression-free survival (PFS) (HR=0.419, P=0.022 & HR=0.429, P=0.025) and good responder (odds ratio [OR]=1.763, P=0.044 & OR=3.881, P=0.011). Patients were further divided into three classes by combination of CRAFITY score and AFP response at 6 weeks [The CAR (CRAFITY score and AFP-Response) classification)]: low CRAFITY score with satisfactory AFP response at 6 weeks (class I), either high CRAFITY score or unsatisfactory AFP response at 6 weeks (class II) and high CRAFITY score together with unsatisfactory AFP response at 6 weeks (class III). ORR was 35.0%, 18.2%, and 0% in class I, II and III patients, respectively (overall P=0.034). Patients in the class I had the best OS and PFS, followed by class II and class III (median OS: not reached vs. 11.1 vs. 4.3 months, log-rank P<0.001; median PFS: 7.9 vs. 6.6 vs. 2.6 months, log-rank P=0.001). Combination CRAFITY score and AFP response at 6 weeks with AUROC predicts OS and tumor response to be 0.809 and 0.798, respectively, better than either CRAFITY score (0.771 & 0.750) or AFP response at 6 weeks (0.725 & 0.680) alone. In conclusions, the CAR classification which combining CRAFITY score and AFP response at 6 weeks provides a practical guidance for atezolizumab plus bevacizumab therapy in unresectable HCC patients.

Project description:BackgroundAlthough atezolizumab plus bevacizumab (Atez/bev) treatment has been developed for unresectable hepatocellular carcinoma (u-HCC), changes in hepatic function during therapy have yet to be reported.AimThis retrospective clinical study aimed to elucidate early responses to Atez/Bev.MethodsFrom September 2020 to April 2021, 171 u-HCC patients undergoing Atez/Bev treatment were enrolled (BCLC stage A:B:C:D = 5:68:96:2). Of those, 75 had no prior history of systemic treatment. Relative changes in hepatic function and therapeutic response were assessed using albumin-bilirubin (ALBI) score and Response Evaluation Criteria in Solid Tumors (RECIST), ver. 1.1, respectively.ResultsIn initial imaging examination findings, objective response rates for early tumor shrinkage and disease control after 6 weeks (ORR-6W/DCR-6W) were 10.6%/79.6%. Similar response results were observed in patients with and without a past history of systemic treatment (ORR-6W/DCR-6W = 9.7%/77.8% and 12.2%/82.9%), as well as patients in whom Atez/Bev was used as post-progression treatment following lenvatinib (ORR-6W/DCR-6W = 7.7%/79.5%), for which no known effective post-progression treatment has been established. In 111 patients who underwent a 6-week observation period, ALBI score was significantly worsened at 3 weeks after introducing Atez/Bev (-2.525 ± 0.419 vs -2.323 ± 0.445, p < .001), but then recovered at 6-weeks (-2.403 ± 0.452) as compared to 3-weeks (p = .001). During the observation period, the most common adverse events were appetite loss (all grades) (12.3%), general fatigue/hypertension (all grades) (11.1%, respectively), and urine protein (all grades) (10.5%).ConclusionAtez/Bev might have therapeutic potential not only as first but also later-line treatment of existing molecular target agents. In addition, this drug combination may have less influence on hepatic function during the early period, as the present patients showed a good initial therapeutic response.

Project description:BackgroundA growing body of evidence suggests that non-viral hepatocellular carcinoma (HCC) might benefit less from immunotherapy.Materials and methodsWe carried out a retrospective analysis of prospectively collected data from consecutive patients with non-viral advanced HCC, treated with atezolizumab plus bevacizumab, lenvatinib, or sorafenib, in 36 centers in 4 countries (Italy, Japan, Republic of Korea, and UK). The primary endpoint was overall survival (OS) with atezolizumab plus bevacizumab versus lenvatinib. Secondary endpoints were progression-free survival (PFS) with atezolizumab plus bevacizumab versus lenvatinib, and OS and PFS with atezolizumab plus bevacizumab versus sorafenib. For the primary and secondary endpoints, we carried out the analysis on the whole population first, and then we divided the cohort into two groups: non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH) population and non-NAFLD/NASH population.ResultsOne hundred and ninety patients received atezolizumab plus bevacizumab, 569 patients received lenvatinib, and 210 patients received sorafenib. In the whole population, multivariate analysis showed that treatment with lenvatinib was associated with a longer OS [hazard ratio (HR) 0.65; 95% confidence interval (CI) 0.44-0.95; P = 0.0268] and PFS (HR 0.67; 95% CI 0.51-0.86; P = 0.002) compared to atezolizumab plus bevacizumab. In the NAFLD/NASH population, multivariate analysis confirmed that lenvatinib treatment was associated with a longer OS (HR 0.46; 95% CI 0.26-0.84; P = 0.0110) and PFS (HR 0.55; 95% CI 0.38-0.82; P = 0.031) compared to atezolizumab plus bevacizumab. In the subgroup of non-NAFLD/NASH patients, no difference in OS or PFS was observed between patients treated with lenvatinib and those treated with atezolizumab plus bevacizumab. All these results were confirmed following propensity score matching analysis. By comparing patients receiving atezolizumab plus bevacizumab versus sorafenib, no statistically significant difference in survival was observed.ConclusionsThe present analysis conducted on a large number of advanced non-viral HCC patients showed for the first time that treatment with lenvatinib is associated with a significant survival benefit compared to atezolizumab plus bevacizumab, in particular in patients with NAFLD/NASH-related HCC.

Project description:Atezolizumab plus bevacizumab (A+B) is used to treat unresectable hepatocellular carcinoma (HCC), but the optimal rescue therapy after A+B remains unclear. Combining locoregional therapy (LRT) with systemic treatment has been shown to improve tumor control, but the role in patients who fail A+B is unknown. We retrospectively enrolled patients who experienced radiological progression after A+B. Objective response rate (ORR), disease control rate (DCR), post progression survival (PPS), and secondary progression-free survival (PFS) were evaluated by modified RECIST. Inverse probability weighting (IPW) was used to balance baseline clinical features. A total of 61 patients were enrolled with a median age of 60.7 years, 83.6% male, 88.5% viral hepatitis-related, and 60.7% without prior systemic treatment before A+B. Patients receiving sequential therapies had significantly longer PPS than supportive care (10.5 vs. 2.3 months, P<0.0001). Among 37 patients received sequential systemic treatment, 18 received combined LRT. The median follow-up after post A+B failure was 6.6 months. The combined LRT group had higher ORR (27.8 vs. 0%, P=0.0197) and DCR (72.2 vs. 26.3%, P=0.0052) than systemic alone group. The median PPS and secondary PFS were significantly longer in combined LRT group (PPS: 12.2 vs. 5.8 months, P=0.0070; PFS: 5.0 vs. 2.6 months, P=0.0134) than systemic alone group. After IPW analysis, patients with combined LRT had superior PPS and secondary PFS. The incidence rates of AEs were higher in LRT combination compared to systemic alone (any grade AEs: 94.4 vs. 63.2%, P=0.0422; severe AEs: 33.3 vs. 5.3%, P=0.0422). No significant albumin-bilirubin index changed in the first 3 months in combined LRT group (0.966 [0.647-1.443], P=0.867) though a trend of deterioration in systemic alone group. In conclusion, sequential systemic therapy provides survival benefits after A+B failure. Furthermore, combining LRT with systemic treatment could provide better tumor responses and survival benefits with acceptable toxicity than systemic therapy alone.
