A Study of Tiragolumab in Combination With Atezolizumab in Chemotherapy-Naïve Patients With Locally Advanced or Metastatic Non-Small Cell Lung Cancer

April 13, 2026 updated by: Genentech, Inc.

A Phase II, Randomized, Blinded, Placebo-Controlled Study of Tiragolumab, An Anti-TIGIT Antibody, In Combination With Atezolizumab In Chemotherapy-Naïve Patients With Locally Advanced Or Metastatic Non-Small Cell Lung Cancer

This study will evaluate the safety and efficacy of tiragolumab plus atezolizumab compared with placebo plus atezolizumab in chemotherapy-naive patients with locally advanced unresectable or metastatic PD-L1-selected non-small cell lung cancer (NSCLC), excluding patients with a sensitizing EGFR mutation or ALK translocation.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Objective Response Rate (ORR)
Time Frame: From baseline until a total of 80 progression-free survival (PFS) events have occurred (up to approximately 11 months)
ORR was defined as a complete response (CR) or partial response (PR) on two consecutive occasions ≥ 4 weeks apart, as determined by the investigator according to RECIST v1.1. CR was defined as disappearance of all target and non-target lesions and normalization of tumor marker levels. Any pathological lymph nodes (whether target or non-target lesions) must have a reduction in short axis to <10 millimeters (mm). PR was defined as at least a 30% decrease in the sum of diameters (SOD) of all target lesions, taking as reference the baseline SOD, in the absence of CR. Percentages have been rounded off.
From baseline until a total of 80 progression-free survival (PFS) events have occurred (up to approximately 11 months)
Progression-free Survival (PFS)
Time Frame: From baseline until a total of 80 PFS events have occurred (up to approximately 11 months)
PFS was defined as the time from randomization to the first occurrence of PD, as determined by the investigator according to RECIST v1.1, or death from any cause, whichever occurred first. PD was defined as at least a 20% increase in the SOD of target lesions, taking as reference the smallest SOD at prior timepoints (including baseline) or unequivocal progression of existing non-target lesions. In addition to the relative increase of 20%, the SOD must also demonstrate an absolute increase of ≥5 mm. Kaplan-Meier (KM) methodology was used to estimate the median PFS.
From baseline until a total of 80 PFS events have occurred (up to approximately 11 months)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Duration of Objective Response (DOR)
Time Frame: Up to approximately 36 months
DOR was defined as the time from the first occurrence of a documented objective response (OR) (CR or PR) to PD, as determined by the investigator according to RECIST v1.1, or death from any cause, whichever occurred first. CR was defined as the disappearance of all target and non-target lesions and normalization of tumor marker levels. Any pathological lymph nodes (whether target or non-target lesions) must have a reduction in short axis to <10 mm. PR was defined as at least a 30% decrease in the SOD of all target lesions, taking as reference the baseline SOD, in the absence of CR. PD was defined as at least a 20% increase in the SOD of target lesions, taking as reference the smallest SOD at prior timepoints (including baseline) or unequivocal progression of existing non-target lesions. In addition to the relative increase of 20%, the SOD must also demonstrate an absolute increase of ≥5 mm. KM methodology was used to estimate the median DOR.
Up to approximately 36 months
Overall Survival (OS)
Time Frame: Up to approximately 36 months
OS was defined as the time from randomization to death from any cause. KM methodology was used to estimate the median OS.
Up to approximately 36 months
Number of Participants With Adverse Events (AEs)
Time Frame: From initiation of study drug up to approximately 83.7 months
An AE was any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
From initiation of study drug up to approximately 83.7 months
Minimum Serum Concentration (Cmin) of Tiragolumab
Time Frame: Predose on Day 1 of Cycles 1, 3 and 11 (Cycle length = 21 days)
Predose on Day 1 of Cycles 1, 3 and 11 (Cycle length = 21 days)
Cmin of Atezolizumab
Time Frame: Predose on Day 1 of Cycles 1, 3 and 11 (Cycle length = 21 days)
Predose on Day 1 of Cycles 1, 3 and 11 (Cycle length = 21 days)
Number of Participants With Treatment-Emergent Anti-drug Antibodies (ADAs) to Tiragolumab
Time Frame: Up to approximately 36 months
Participants who received tiragolumab were considered to be treatment-emergent ADA-positive if they were ADA-negative or had missing data at baseline but developed an ADA response following tiragolumab exposure (treatment-induced ADA response), or if they were ADA-positive at baseline and the titer of one or more post-baseline samples was at least 0.60 titer units (t.u.) greater than the titer of the baseline sample (treatment-enhanced ADA response). Participants with a positive post-baseline sample has been reported here.
Up to approximately 36 months
Number of Participants With Treatment-Emergent ADAs to Atezolizumab
Time Frame: Up to approximately 36 months
Participants who received atezolizumab were considered to be treatment-emergent ADA-positive if they were ADA-negative or had missing data at baseline but developed an ADA response following atezolizumab exposure (treatment-induced ADA response), or if they were ADA-positive at baseline and the titer of one or more post-baseline samples was at least 0.60 titer units (t.u.) greater than the titer of the baseline sample (treatment-enhanced ADA response). Participants with a positive post-baseline sample has been reported here.
Up to approximately 36 months
