ABSTRACT
BACKGROUND & AIMS: Sorafenib is the standard of care for advanced hepatocellular carcinoma (HCC). Combining sorafenib with another treatment, to improve overall survival (OS) within an acceptable safety profile, might be the next step forward in the management of patients with advanced HCC. We aimed to assess whether a combination of sorafenib and a statin improved survival in patients with HCC. METHODS: The objective of the PRODIGE-11 trial was to compare the respective clinical outcomes of the sorafenib-pravastatin combination (arm A) versus sorafenib alone (arm B) in patients with advanced HCC. Child-Pugh A patients with advanced HCC who were naive to systemic treatment (nâ¯=â¯323) were randomly assigned to sorafenib-pravastatin combination (nâ¯=â¯162) or sorafenib alone (nâ¯=â¯161). The primary endpoint was OS; secondary endpoints were progression-free survival, time to tumor progression, time to treatment failure, safety, and quality of life. RESULTS: After randomization, 312 patients received at least 1 dose of study treatment. After a median follow-up of 35â¯months, 269 patients died (arm A: 135; arm B: 134) with no difference in median OS between treatments arms (10.7â¯months vs. 10.5â¯months; hazard ratioâ¯=â¯1.00; pâ¯=â¯0.975); no difference was observed in secondary survival endpoints either. In the univariate analysis, the significant prognostic factors for OS were CLIP score, performance status, and quality of life scores. The multivariate analysis showed that the only prognostic factor for OS was the CLIP score. The main toxicity was diarrhea (which was severe in 11% of patients in arm A, and 8.9% in arm B), while severe nausea-vomiting was rare, and no toxicity-related deaths were reported. CONCLUSION: Adding pravastatin to sorafenib did not improve survival in patients with advanced HCC. LAY SUMMARY: Sorafenib has proven efficacy for the treatment of patients with advanced hepatocellular carcinoma. However, overall survival remains poor in these patients, so we were interested to see if the addition of a statin, pravastatin, improved outcomes in patients with advanced HCC. This randomized-controlled trial demonstrated that the sorafenib-pravastatin combination did not improve overall survival in this study population compared to sorafenib alone. Clinical trial number: NCT01075555.

BACKGROUND: Cytotoxic chemotherapy is generally ineffective in patients with hepatocellular carcinoma. We assessed the intravenous perfusion of doxorubicin-loaded nanoparticles in patients with hepatocellular carcinoma in whom previous sorafenib therapy had failed. METHODS: We did a multicentre, open-label, randomised, controlled phase 3 trial at 70 sites in 11 countries. Patients with hepatocellular carcinoma with one or more previous systemic therapies, including sorafenib, were randomly assigned to receive 30 mg/m2 doxorubicin-loaded nanoparticles (30 mg/m2 group), 20 mg/m2 doxorubicin-loaded nanoparticles (20 mg/m2 group), or standard care using a computer-generated randomisation list prepared by the funder and stratified by geographic region. Patients in the experimental groups received perfusion of the drug every 4 weeks and those in the control group received any systemic anticancer therapy (except sorafenib) as per investigator decision. The primary endpoint was overall survival in the intention-to-treat population. Safety was assessed in the population of patients who received at least one dose of their assigned treatment. This trial is registered with ClinicalTrials.gov, number NCT01655693. FINDINGS: Between June 15, 2012, and Jan 27, 2017, 541 patients were screened, of whom 144 were excluded and 397 were randomly assigned to one of the groups (133 to the 30 mg/m2 group; 130 to the 20 mg/m2 group; and 134 to the control group). Median follow-up was 22·7 months (IQR 11·2-34·9). After pooling the doxorubicin groups for the efficacy analysis, median overall survival was 9·1 months (95% CI 8·1-10·4) in the pooled doxorubicin-loaded nanoparticles group and 9·0 months (7·1-11·8) in the control group (HR 1·00 [95% CI 0·78-1·28], two-sided p=0·99). 227 (94%) of 242 patients who received doxorubicin-loaded nanoparticles and 100 (75%) of 134 patients in the control group had at least one treatment-emergent adverse event. The most common drug-related grade 3 or 4 treatment-emergent adverse events were neutropenia (25 [10%] of 242 treated with doxorubicin-loaded nanoparticles and eight [6%] of 134 in the control group), asthenia (six [2%] and four [3%]), and thrombocytopenia (three [1%] and ten [7%]). Six (2%) patients treated with doxorubicin-loaded nanoparticles and one (1%) of those in the control group were deemed by investigators to have had a drug-related death. Serious adverse events occurred in 74 (31%) patients who received doxorubicin-loaded nanoparticles and 48 (36%) in the control group. INTERPRETATION: Doxorubicin-loaded nanoparticles did not improve overall survival for patients with hepatocellular carcinoma in whom previous sorafenib treatment had failed. FUNDING: Onxeo.

Ribavirin-induced anemia is the major side effect observed during HCV therapy. In an in vitro study, we recently discovered that DHEA can strongly inhibit this adverse event. We also evaluated a possible link between pre-treatment serum DHEA and hemoglobin during HCV therapy. Among the 108 patients of our cohort serum baseline DHEA levels were associated with hemoglobin levels at week 12 of treatment (r = 0.35; P = 0.0021). Patients with low baseline serum DHEA developed severe anemia. A serum level of DHEA less than 1,500 ng/ml had a sensitivity of 94.3% and a positive predictive value of 93.1% for the detection of hemoglobin less than 11 g/dl during the first 12 week of treatment. With pre-treatment DHEA levels below the cutoff, anemia was observed in 24.4% and 60.5% of patients treated with dual therapy and triple therapy, respectively, versus 0% and 15% of patients with higher DHEA levels. At week 12, the mean difference between patients with serum DHEA below and above the cutoff, in terms of absolute hemoglobin for dual and triple therapy groups were 1.2 and 1.7 g/dl, respectively (P = 0.005 and <0.001). Pretreatment DHEA levels are associated with hemoglobin levels during treatment. Based on these data, pretreatment assay of DHEA could be considered systematically in order to propose DHEA supplementation to potentiate the efficacy of the current and future use of ribavirin for HCV and HEV therapy.

BACKGROUND: Today, treatment of chronic hepatitis C is based on a synergistic combination of pegylated interferon and ribavirin with antiprotease inhibitors. Haemolytic anaemia, which is the major side effect of ribavirin treatment, disrupts ribavirin treatment compliance and varies significantly from one patient to another. There is an individual susceptibility to ribavirin haemolysis. With a view to studying haemolysis, and thus optimizing the treatment response, we have developed a new in vitro tool for analysing the ribavirin-induced lysis of red blood cells. METHODS: Resuspended red blood cells were incubated with isotonic buffer and a range of concentrations of ribavirin. Haemolysis was quantified by spectrophotometric measurement of the supernatant at 540 nm. The assay was used to test the effects of various compounds and to investigate the susceptibility of patients to haemolytic anaemia. RESULTS: In our assay, the degree of haemolysis is dependent on the ribavirin concentration used and can be inhibited by the addition of dipyridamole (50% inhibitory concentration [IC(50)] 30 µM), ATP or glutathione (IC(50) 1.63 mM and 767 µM, respectively). We observed a strong decrease in red blood cell haemolysis in the presence of the ribavirin prodrug viramidine (Taribavirin(®)). When testing the performance of this assay with blood from 24 patients before treatment, we observed a strong correlation between in vitro haemolysis before treatment and the decrease in haemoglobin levels seen in vivo during subsequent treatment (P<0.001). CONCLUSIONS: With this new tool it is possible to better evaluate individual susceptibility to ribavirin-induced haemolysis before the start of treatment. In addition, this model will enable the mechanism of ribavirin-induced anaemia to be further explored and allow molecules that could reduce ribavirin haemolysis to be screened and tested in vitro. This approach could help optimize current and future therapeutic strategies involving ribavirin in the treatment of chronic hepatitis C.

Proteins of the BCL2 family are key regulators of apoptosis. Their expression levels are frequently altered in cancers, enabling tumor cells to survive. To gain insight into the pathogenesis of hepatocellular carcinoma (HCC), we performed a comprehensive survey of the expression of the members of the BCL2 family in samples obtained from surgically resected HCCs. Here, we report the occurrence of a new molecular anomaly, consisting of a strong reduction in the expression of the proapoptotic protein BAD in HCC compared with surrounding nontumoral tissue. We investigate the function of BAD in a panel of HCC cell lines. Using gene overexpression and RNA interference, we show that BAD is involved in the cytotoxic effects of sorafenib, a multikinase blocker, which is currently the sole therapeutic drug effective for the treatment of HCC. Finally, we report that ABT-737, a compound that interacts with proteins of the BCL2 family and exhibits a BAD-like reactivity, sensitizes HCC cells toward sorafenib-induced apoptosis. Collectively, our findings indicate that BAD is a key regulator of apoptosis in HCC and an important determinant of HCC cell response to sorafenib.
