Clinical Trial Summary

There is an unmet need for patients with intermediate stage hepatocellular carcinoma (HCC). It is known that local tumor ablation can increase tumor immunogenicity by releasing tumor associated antigens, potentially increasing the response to immune therapy not just locally, but systemically. In addition, there is now positive data with immune therapy in advanced HCC, there is renewed interest in the combination of local therapy and systemic therapy in Barcelona Clinic Liver Clinic B (BCLC B) patients with systemic therapies other than sorafenib. Based on this data, the investigators plan to examine the atezolizumab and bevacizumab combination with Transarterial Chemoembolization (TACE) in patients with BCLC B HCC.

Description:

Targeting the Programmed Death-Ligand 1 (PD-L1) pathway with atezolizumab has demonstrated activity in patients with advanced malignancies who have failed standard-of-care therapies. Objective responses have been observed across a broad range of malignancies, including Non-Small-Cell Lung Cancer (NSCLC), urothelial carcinoma, Renal Cell Carcinoma (RCC), melanoma, colorectal cancer, head and neck cancer, gastric cancer, breast cancer, and sarcoma (see Atezolizumab Investigator's Brochure for detailed efficacy results).

Atezolizumab has been generally well tolerated. Adverse events with potentially immune-related causes consistent with an immunotherapeutic agent, including rash, influenza-like illness endocrinopathies, hepatitis or transaminitis, pneumonitis colitis, and myasthenia gravis, have been observed (see Atezolizumab Investigator's Brochure for detailed safety results). To date, these events have been manageable with treatment or interruption of atezolizumab treatment.

The combination of atezolizumab and bevacizumab in HCC has been well studied in both the phase 1 G030140 study and the phase 3 IMBrave150 study with response rates of 36% and 27% respectively. A phase 2 study of bevacizumab and TACE showed that the combination can be safely administered on the same day. Given concern for risk of bleeding with bevacizumab, all patients on these two studies had recent Endoscopic Gastroduodenoscopies (EGDs) and no patients with untreated varices were included. The risk of bleeding on both studies were reported as low, and risk of benefit was presented as outweighing risk.

This trial will enroll patients with HCC who have BCLC B disease and are not candidates for curative treatment but are candidates for TACE. Typically, these patients would be treated with local treatment alone, but given the relatively poor prognosis and limited treatment options for these patients, this population is considered appropriate for trials of novel therapeutic candidates. The benefit-risk ratio for atezolizumab and bevacizumab in combination with TACE is expected to be acceptable in this setting.

Please note the most current guidelines for Avastin are: Exclusionary: Current or recent (< 10 days prior to initiation of study treatment) use of aspirin (> 325 mg/day), or clopidogrel (> 75 mg/day) Allowed: Note: The use of full-dose oral or parenteral anticoagulants for therapeutic purpose is permitted as long as the INR and/or aPTT is within therapeutic limits (according to institution standards) within 7 days prior to initiation of study treatment and the patient has been on a stable dose of anticoagulants for = 2 weeks prior to initiation of study treatment. Prophylactic use of anticoagulants is allowed.
