What You Need to Know Before You Apply

What is the purpose of this trial?

This will be a nonrandomized, single arm feasibility study with the primary goal of evaluating the safety profile of the combination of atezolizumab and bevacizumab in patients with advanced/metastatic HCC with Child-Pugh B7 and B8 liver disease who have received no prior systemic therapy.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on systemic immunosuppressive medications, you must stop them 6 weeks before starting the trial, unless they are low-dose corticosteroids or certain other exceptions.

Is the combination of Atezolizumab and Bevacizumab safe for treating liver cancer?

The combination of Atezolizumab and Bevacizumab has been studied for liver cancer and is generally considered safe, but it can cause side effects like high blood pressure, tiredness, and protein in the urine. Bleeding was more common in patients taking this combination compared to another treatment, so monitoring is recommended. ^{1 2 3 4 5}

How is the drug combination of atezolizumab and bevacizumab unique for liver cancer treatment?

The combination of atezolizumab and bevacizumab is unique because it is the new standard first-line treatment for advanced liver cancer, offering improved survival compared to previous options like sorafenib. This combination therapy represents a significant advancement in managing liver cancer across various stages. ^{2 6 7 8 9}

What data supports the effectiveness of the drug combination Atezolizumab and Bevacizumab for liver cancer?

Research shows that the combination of atezolizumab and bevacizumab improves overall survival in patients with advanced liver cancer compared to the previous standard treatment, sorafenib. This combination is now considered the gold standard for first-line treatment of advanced liver cancer. ^{2 6 7 10 11}

Published Research Related to This Trial

The combination of atezolizumab and bevacizumab has been shown to significantly increase overall survival in patients with advanced hepatocellular carcinoma (HCC) compared to sorafenib.

The FDA's approval of this combination therapy marks a significant advancement in the treatment of HCC, potentially changing how the disease is managed across all stages.

Atezolizumab plus Bevacizumab: A Novel Breakthrough in Hepatocellular Carcinoma. Castet, F., Willoughby, CE., Haber, PK., et al.[2022]

In a study of 191 patients with unresectable hepatocellular carcinoma (HCC), the combination therapy of atezolizumab and bevacizumab showed similar overall survival and progression-free survival rates in older patients (≥65 years) compared to younger patients (<65 years), indicating its efficacy across age groups.

The safety profile of the combination therapy was comparable between older and younger patients, with similar rates of treatment-related adverse events, including severe adverse events, suggesting that older patients can tolerate this treatment as well as younger patients.

The combination of atezolizumab and bevacizumab has recently become the new standard of care for patients with advanced hepatocellular carcinoma (HCC), replacing sorafenib, which was the standard for over a decade.

This review highlights practical aspects of using the atezolizumab and bevacizumab combination, including evidence for its efficacy, indications for use, management of side effects, and areas needing further research, making it a valuable resource for clinicians.

In the phase 3 IMbrave050 study involving 668 patients with high-risk hepatocellular carcinoma, adjuvant treatment with atezolizumab plus bevacizumab significantly improved recurrence-free survival compared to active surveillance, indicating its potential efficacy as a post-surgery treatment.

However, the treatment was associated with a higher incidence of severe adverse events (41% of patients) compared to the active surveillance group (13%), highlighting the need for careful consideration of the benefit-risk profile in these patients.

Atezolizumab combined with bevacizumab demonstrated good efficacy in treating advanced hepatocellular carcinoma (HCC), with a pooled overall response rate of 26% and a median overall survival of 14.7 months based on a review of 23 studies involving 3168 patients.

The treatment was well-tolerated, with 83% of patients experiencing any grade adverse events, and 30% experiencing grade 3 or higher adverse events, indicating that while side effects are common, the combination therapy remains a viable first-line option for advanced HCC.

Atezolizumab in combination with bevacizumab has been approved by the FDA for treating unresectable hepatocellular carcinoma (HCC), showing improved overall survival (OS) and progression-free survival (PFS) compared to sorafenib, with a hazard ratio of 0.58 for OS.

The combination therapy resulted in a median PFS of 6.8 months versus 4.3 months for sorafenib, although it was associated with a higher incidence of hemorrhage (25% vs. 17%), highlighting the need for careful monitoring of patients.

FDA Approval Summary: Atezolizumab Plus Bevacizumab for the Treatment of Patients with Advanced Unresectable or Metastatic Hepatocellular Carcinoma. Casak, SJ., Donoghue, M., Fashoyin-Aje, L., et al.[2022]

In a multicenter study of 121 patients with advanced hepatocellular carcinoma (HCC) treated with atezolizumab plus bevacizumab (Ate/Bev), the objective response rate was 24% and the disease control rate was 76%, demonstrating real-world efficacy similar to phase III trial results.

The most common severe side effect was an increase in aspartate aminotransferase levels (10.7%), and factors like elevated baseline neutrophil-to-lymphocyte ratio were linked to poorer progression-free and overall survival, indicating the need for careful monitoring in these patients.

In a study of 286 patients with unresectable hepatocellular carcinoma treated with atezolizumab plus bevacizumab, treatment-related hypertension was linked to better progression-free survival, with a median of 12.6 months compared to 6.5 months for those without hypertension.

Conversely, treatment-related fatigue was associated with shorter overall survival, indicating that while hypertension may signal a positive response to treatment, fatigue could indicate poorer outcomes.

Adverse events as potential predictive factors of therapeutic activity in patients with unresectable hepatocellular carcinoma treated with atezolizumab plus bevacizumab. Tada, T., Kumada, T., Hiraoka, A., et al.[2023]

In a real-world study of 61 patients with hepatocellular carcinoma (HCC), the combination of atezolizumab and bevacizumab showed a median progression-free survival (PFS) of 5.4 months and an objective response rate (ORR) of 35.3%.

The treatment was found to be safe, with a high incidence of adverse events (98.0%), primarily hepatic disorders, but it remained effective even in patients with prior treatment histories or varying liver function as indicated by albumin-bilirubin (ALBI) grades.

Atezolizumab plus bevacizumab therapy shows promising efficacy for advanced hepatocellular carcinoma (HCC), achieving an objective response rate of 15.6% and a high disease control rate of 93.8% among 34 patients, regardless of liver function or treatment line.

Following the failure of atezolizumab plus bevacizumab therapy, lenvatinib treatment can also be effective, but careful monitoring of liver function is necessary, as indicated by significant reductions in liver function scores in patients receiving lenvatinib.

Atezolizumab plus bevacizumab (Atez/Bev) is safe and effective for treating elderly patients with unresectable hepatocellular carcinoma (HCC), as shown in a study of 317 patients where age did not negatively impact survival outcomes.

There were no significant differences in treatment-related adverse events between elderly and non-elderly patients, indicating that Atez/Bev can be administered safely across different age groups.
