Atezolizumab, sold under the brand name Tecentriq among others, is a monoclonal antibody medication used to treat urothelial carcinoma, non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), hepatocellular carcinoma and alveolar soft part sarcoma, [9] [11] but discontinued for use in triple-negative breast cancer (TNBC). [12]
The subcutaneous injection of atezolizumab and hyaluronidase was evaluated in IMscin001 (NCT03735121), an open-label, multi-center, international, randomized trial in adults with locally advanced or metastatic non-small cell lung cancer who were not previously exposed to cancer immunotherapy and who had disease progression following treatment with platinum-based chemotherapy.

Atezolizumab (Tecentriq) is a fully humanised IgG1 (immunoglobulin 1) antibody developed by Roche Genentech. In 2016, the FDA approved atezolizumab for urothelial carcinoma and non-small cell lung cancer. Avelumab (Bavencio) is a fully human IgG1 antibody developed by Merck Serono and Pfizer.
NSCLC cells expressing programmed death-ligand 1 (PD-L1) could interact with programmed death receptor 1 (PD-1) expressed on the surface of T cells and result in decreased tumor cell kill by the immune system. Atezolizumab is an anti-PD-L1 monoclonal antibody. Nivolumab and Pembrolizumab are anti-PD-1 monoclonal antibodies.
Checkpoint inhibitor therapy is a form of cancer immunotherapy.The therapy targets immune checkpoints, key regulators of the immune system that when stimulated can dampen the immune response to an immunologic stimulus.
Atezolizumab, sold under the brand name Tecentriq among others, is a monoclonal antibody medication used to treat urothelial carcinoma, non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), hepatocellular carcinoma and alveolar soft part sarcoma, [73] [74] but discontinued for use in triple-negative breast cancer (TNBC). [75]
The study enrolled 34 patients, 28 of which underwent surgery to resect the PDAC. 19 of the patients who had undergone surgery then received atezolizumab, an immune checkpoint inhibitor. 16 of the patients on atezolizumab then received autogene cevumeran. 1 patient was considered to have insufficiently many neoantigens to manufacture the vaccine.
Small-cell lung carcinoma (SCLC) has long been divided into two clinicopathological stages, termed limited stage (LS) and extensive stage (ES). [8] The stage is generally determined by the presence or absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy ...
