Atezolizumab
Atezolizumab is a humanized IgG1 monoclonal antibody therapy that blocks CD274 molecule, an immune checkpoint protein expressed on tumor cells and tumor-infiltrating immune cells.
Atezolizumab is a humanized IgG1 monoclonal antibody therapy that blocks CD274 molecule, an immune checkpoint protein expressed on tumor cells and tumor-infiltrating immune cells. Developed by Genentech/Roche and marketed as Tecentriq, it belongs to the class of immune checkpoint inhibitors used in cancer immunotherapy. By binding PD-L1, atezolizumab prevents its engagement of Programmed cell death 1 (PD-1) on T cells, releasing the inhibitory signal that suppresses cytotoxic T-cell responses within the tumor microenvironment and restoring antitumor immunity. Unlike agents directed at the receptor itself — such as nivolumab and pembrolizumab — atezolizumab targets the ligand, leaving PD-1/PD-L2 interactions intact. It is approved across several solid tumors, including non-small cell lung cancer (NSCLC), hepatocellular carcinoma (HCC), triple-negative breast cancer, and urothelial carcinoma, and is administered intravenously as well as in a subcutaneous formulation.
In practice, atezolizumab is used both as monotherapy and, more commonly, within combination regimens. Its most established combination pairs it with bevacizumab, an anti-VEGF antibody, as first-line treatment for unresectable HCC — a regimen that displaced sorafenib as standard of care and provides the rationale for pairing checkpoint blockade with antiangiogenic therapy, since VEGF signaling itself contributes to an immunosuppressive tumor microenvironment. It is also combined with cytotoxic chemotherapy such as carboplatin and paclitaxel in lung and breast cancer. Related soluble mediators, including TGF-β1, Interleukin-6 (IL-6), and interferon gamma, together with tumor PD-L1 expression and circulating markers such as soluble PD-L1 and cell-free tumor DNA, are actively investigated as determinants of response. As with other checkpoint inhibitors, treatment carries a characteristic spectrum of immune-related adverse events — among them myocarditis, myositis, encephalitis, and endocrinopathies such as fulminant type 1 diabetes — that shape patient selection and monitoring, particularly in patients with underlying liver disease.

Atezolizumab-Bevacizumab in HCC
Atezolizumab plus bevacizumab remains the central first-line strategy for unresectable hepatocellular carcinoma, with real-world cohorts refining survival predictors and treatment pathways. Comparisons with durvalumab plus tremelimumab, and trials adding ipilimumab, are testing sequencing and intensified combinations. Response assessment repeatedly examines RECIST, mRECIST, DCP, muscle status, and early survival dynamics. Cost, proteinuria, salvage TACE, and liver transplantation remain practical questions.

PD-L1 Immunotherapy Combinations
PD-L1 blockade is being paired with antiangiogenic drugs, costimulatory antibodies, kinase inhibitors, radiation, and engineered delivery systems across solid tumors. Renal and liver cancers recur clinically, while preclinical work seeks stronger tumor immunogenicity and local antibody production. Baseline immune state and myeloid remodeling are emerging as response determinants. Toxicities such as encephalitis and pernicious anemia keep safety and patient selection open.

Atezolizumab in Lung Cancer
Atezolizumab is moving across metastatic, neoadjuvant, and early-stage non-small cell lung cancer settings, usually with platinum chemotherapy, bevacizumab, or stereotactic radiation. Tiragolumab combinations focus on improving outcomes in PD-L1-high disease, while subcutaneous delivery addresses treatment practicality. Gut microbiota and immune-nutritional status are being explored as predictors of progression-free and overall survival. The main open issues are durable benefit, added toxicity, and which earlier-stage patients should receive combined therapy.

Atezolizumab is used for recurrent or new liver cancer in liver-transplant recipients receiving tacrolimus
The subject is recurrent or newly diagnosed liver cancer after liver transplantation, treated with lenvatinib and atezolizumab under ongoing low-dose tacrolimus 42262196Jun. The set otherwise presents atezolizumab mainly as therapy for unresectable or metastatic cancer, perioperative blockade, or combination treatment in non-transplant patients. This study therefore gives atezolizumab a distinct role in treating liver cancer within an immunosuppressed transplant-recipient population, where the treatment must be balanced against the transplanted graft and its immunosuppressive regimen.
