In the phase III HIMALAYA study (NCT03298451), STRIDE (Single Tremelimumab Regular Interval Durvalumab) significantly improved overall survival (OS) vs. sorafenib in unresectable HCC and demonstrated long-term survival benefits. We report an updated exploratory analysis of OS after 5 years of follow-up, including survival by multiple tumour response measures. Participants were randomised to STRIDE (tremelimumab plus durvalumab), durvalumab or sorafenib. OS, depth of response and serious adverse events were assessed. Extended long-term survivors (≥48 months beyond randomisation) were described. The updated data cut-off was 01 March 2024. Median (95% CI) follow-up durations were 62.49 (59.47-64.79) months (STRIDE) and 59.86 (58.32-61.54) months (sorafenib). The OS hazard ratio (95% CI) for STRIDE vs. sorafenib was 0.76 (0.65-0.89). OS rates at 60 months for STRIDE vs. sorafenib were 19.6% vs. 9.4% overall, 28.7% vs. 12.7% in participants achieving disease control per RECIST v1.1, and 50.7% vs. 26.3% in participants achieving >25% tumour shrinkage. No late-onset treatment-related serious adverse events were reported for STRIDE. There were more extended long-term survivors with STRIDE (83/393, 21.1%) than sorafenib (45/389, 11.6%), and extended long-term survival occurred across all clinically relevant subgroups. At 5 years, STRIDE sustained an OS benefit vs. sorafenib and maintained a manageable safety profile. OS benefit with STRIDE was improved in participants with disease control. Data suggest that any degree of tumour shrinkage with STRIDE can be associated with improved OS, indicating that conventional response measures may not fully capture the benefits of STRIDE. Nevertheless, participants experiencing deep responses appear to have the greatest benefit. STRIDE continues to set new benchmarks in unresectable HCC with 1 in 5 patients alive at 5 years. NCT03298451. The phase III HIMALAYA study showed that STRIDE (Single Tremelimumab Regular Interval Durvalumab) improved overall survival (OS) vs. sorafenib in participants with unresectable HCC, including after 4 years of follow-up. Understanding the efficacy and safety of STRIDE over the longer term is important for healthcare providers; here, we demonstrate that STRIDE sustained an OS benefit vs. sorafenib and maintained a manageable safety profile after 5 years of follow-up. OS benefit with STRIDE was improved in participants with disease control and any degree of tumour shrinkage, indicating that conventional response measures may not fully capture the benefits of STRIDE. These findings are important as they set new benchmarks in unresectable HCC and may help guide clinical decisions in the future.

Background and Aims: The effectiveness of systemic treatment in advanced hepatocellular carcinoma (HCC) depends on the selection of patients, management of cirrhosis complications and expertise to treat adverse events. The aims of the study are to assess the frequency and management of cardiovascular events in HCC patients treated with sorafenib (SOR) and to create a scale to predict the onset of major adverse cardiovascular events (MACE).Method: Observational retrospective study with consecutive HCC patients treated with SOR between 2007 and 2019 in a western centre. In order to classify cardiovascular risk pre‐SOR, we designed the CARDIOSOR scale with age, hypertension, diabetes, dyslipidaemia and peripheral vascular disease. Other adverse events, dosing and outcome data were collected during a homogeneous protocolled follow‐up.Results: Two hundred ninety‐nine patients were included (219 BCLC‐C). The median overall survival was 11.1 months (IQR 5.6‐20.5), and duration of treatment was 7.4 months (IQR 3.3‐14.7). Seventeen patients (6%) stopped SOR due to cardiovascular event. Thirty‐three patients suffered MACE (7 heart failure, 11 acute coronary syndrome, 12 cerebrovascular accident and 8 peripheral vascular ischemia); 99 had a minor cardiovascular event, mainly hypertension (n = 81). Age was the only independent factor associated to MACE (HR 1.07; 95% CI 1.03‐1.12; P = .002). The CARDIOSOR scale allows to identify the group of patients with higher risk of MACE (sHR 3.4; 95% CI 1.4‐6.7; P = .04).Conclusion: The incidence of cardiovascular events in HCC patients treated with SOR is higher than expected. Multidisciplinary approach and clinical tools like CARDIOSOR scale could be helpful to manage these patients.

Pravastatin has demonstrated anti-tumor activity in preclinical and clinical studies. This multicentric randomized double-blind placebo-controlled phase II study (NCT01418729) investigated the efficacy and safety of sorafenib + pravastatin combination on the overall survival (OS) and time to progression (TTP) of patients with advanced hepatocellular carcinoma (aHCC). A total of 31 patients were randomized. Median OS did not differ between both groups (12.4 months for the sorafenib + pravastatin group vs. 11.6 months for the control group). Of note, however, the radiological TTP was higher in patients treated with sorafenib + pravastatin than in the control group (9.9 months vs. 3.2 months; p = 0.008). Considering all the study population, the presence of portal vein thrombosis (PVT) was associated with worse OS, being lower in patients with PVT compared to patients without PVT (6.3 months vs. 14.8 months; p = 0.026). Data also showed a decrease in OS in patients with vascular invasion (VI) compared to patients who did not present it (6.3 months vs. 14.8 months; p = 0.041). The group of patients without dermatological events (DE) showed lower OS (6.9 months vs. 14.5 months; p = 0.049). In conclusion, combination of sorafenib + pravastatin was safe and well-tolerated, prolonging the TTP of patients with aHCC but not improving the OS compared to sorafenib + placebo. The absence of PVT and VI and the development of DE are positive prognostic factors of sorafenib response.

Background & Aims: Information about the impact of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) in patients with liver cancer is lacking. This study characterizes the outcomes and mortality risk in this population. Methods: Multicentre retrospective, cross‐sectional, international study of liver cancer patients with SARS‐CoV‐2 infection registered between February and December 2020. Clinical data at SARS‐CoV‐2 diagnosis and outcomes were registered. Results: Two hundred fifty patients from 38 centres were included, 218 with hepatocellular carcinoma (HCC) and 32 with intrahepatic cholangiocarcinoma (iCCA). The median age was 66.5 and 64.5 years, and 84.9% and 21.9% had cirrhosis in the HCC and iCCA cohorts respectively. Patients had advanced cancer stage at SARS‐CoV‐2 diagnosis in 39.0% of the HCC and 71.9% of the iCCA patients. After a median follow‐up of 7.20 (IQR: 1.84–11.24) months, 100 (40%) patients have died, 48% of the deaths were SARS‐CoV‐2‐related. Forty (18.4%) HCC patients died within 30‐days. The death rate increase was significantly different according to the BCLC stage (6.10% [95% CI 2.24–12.74], 11.76% [95% CI 4.73–22.30], 20.69% [95% CI 11.35–31.96] and 34.52% [95% CI 17.03–52.78] for BCLC 0/A, B, C and D, respectively; p = .0017). The hazard ratio was 1.45 (95% CI 0.49–4.31; p = .5032) in BCLC‐B versus 0/A, and 3.13 (95% CI 1.29–7.62; p = .0118) in BCLC‐C versus 0/A in the competing risk Cox regression model. Nineteen out of 32 iCCA (59.4%) died, and 12 deaths were related to SARS‐CoV‐2 infection. Conclusions: This is the largest cohort of liver cancer patients infected with SARS‐CoV‐2. It characterizes the 30‐day mortality risk of SARS‐CoV‐2 infected patients with HCC during this period.
