61MO IMscin001 (part 2: randomized phase III): Pharmacokinetics (PK), efficacy and safety of atezolizumab (atezo) subcutaneous (SC) vs intravenous (IV) in previously treated locally advanced or metastatic non-small cell lung cancer (NSCLC)

Abstract

Atezo (anti–PD-L1) IV is approved in NSCLC, SCLC, triple-negative breast cancer, hepatocellular carcinoma, urothelial carcinoma and unresectable/metastatic melanoma. To reduce treatment burden and improve convenience and efficiencies in healthcare, a novel fixed-dose atezo SC co-formulated with recombinant human hyaluronidase is being developed. We report Part 2 (Phase III) of the open-label, randomized, multicentre IMscin001 study (NCT03735121) to investigate non-inferiority of drug exposure at Cycle 1 after atezo SC vs IV administration in NSCLC.
