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.

[52] [16] Atezolizumab for first-line treatment of metastatic NSCLC with PD-L1 ≥ 50% was approved recently by the FDA, [16] after the IMPOWER110 trial showed a median OS of 20.2 months for patients in the atezolizumab arm, compared with 13.1 months in the chemotherapy arm (p = 0.0106). [53]
PD-1 and PD-L1 inhibitors act to inhibit the association of the programmed death-ligand 1 with its receptor, programmed cell death protein 1 (PD-1). The interaction of these cell surface proteins is involved in the suppression of the immune system and occurs following infection to limit the killing of bystander host cells and prevent autoimmune ...

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.
Antibodies that bind to either PD-1 or PD-L1 and therefore block the interaction may allow the T-cells to attack the tumor. [ 5 ] The discoveries in basic science allowing checkpoint inhibitor therapies led to James P. Allison and Tasuku Honjo winning the Tang Prize in Biopharmaceutical Science and the Nobel Prize in Physiology or Medicine in 2018.
The US Food and Drug Administration (FDA) approved durvalumab for certain types of bladder, lung, and biliary tract cancer: [6] [13] [14]. Adults with locally advanced or metastatic urothelial carcinoma who either have disease progression during or following platinum-containing chemotherapy or have disease progression within twelve months of neoadjuvant or adjuvant treatment with platinum ...
