Medical uses
Atezolizumab/hyaluronidase is a subcutaneous injection version of atezolizumab for all the adult indications as the intravenous formulation of atezolizumab including non-small cell lung cancer, small cell lung cancer, hepatocellular carcinoma, melanoma, and alveolar soft part sarcoma.[2]
History
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.[2] A total of 371 participants were randomized (2:1) to receive subcutaneous atezolizumab and hyaluronidase or intravenous atezolizumab until disease progression or unacceptable toxicity.[2]
