Time frame
Time from start of treatment to time of progression or death, whichever occurs first, assessed up to 2 years.

What was measured

Progression is defined, per RECIST v1.1, as a 20% increase in the sum of the longest diameter of target lesions (the sum must demonstrate an absolute increase of at least 5 mm), or the appearance of new lesions and/or unequivocal progression of non-target lesions. PFS will be summarized using Kaplan-Meier estimates. Will also assess PFS in patients stratified by PD-L1 expression levels in the tumor microenvironment.

Analysis population: Patients without documented PD or death are censored at the last disease assessment date. The PD-L1 assay produced no data due to expired antibody. Stratification by PD-L1 expression levels in the tumor microenvironment cannot be reported.

Groups in this outcome

Group 1 (CYT107, Atezolizumab)

Patients receive CYT107 on days 1, 8, 15, and 22, and atezolizumab on day 8 of cycle 1. Following cycle 1, patients receive atezolizumab on day 1. Cycles with atezolizumab repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Atezolizumab: Given IV Glycosylated Recombinant Human Interleukin-7: Given IM

Group 2 (Atezolizumab)

Patients receive atezolizumab on day 1 of each cycle. Cycles repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Atezolizumab: Given IV

Safety Run in Phase

Patients were not randomized; they were assigned to the experimental arm treatment (atezolizumab + CYT107). Patients receive CYT107 on days 1, 8, 15, and 22, and atezolizumab on day 8 of cycle 1. Following cycle 1, patients receive atezolizumab on day 1. Cycles with atezolizumab repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Atezolizumab: Given IV Glycosylated Recombinant Human Interleukin-7: Given IM
