Study Endpoints

Primary Endpoints

Investigator-assessed Progression-free Survival (PFS) in the Primary Analysis Set (PAS)
From randomization to first occurrence of PD or death from any cause, whichever occurred first (up to approximately 32.3 months)

PFS was defined as the time from randomization to the first occurrence of PD, as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1), or death from any cause, whichever occurred first in the PAS. PD was defined as at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest SOD at prior timepoints (including baseline). Additionally, the sum must also demonstrate an absolute increase of ≥ 5 millimeters (mm) and unequivocal progression of existing non-target lesions. Kalpan-Meier (K-M) method was used to estimate median PFS.

Overall Survival (OS) in the PAS
From randomization to death from any cause (up to approximately 32.3 months)

OS was defined as the time from randomization to death from any cause in the PAS. K-M method was used to estimate median OS.

Arm A vs Arm C: Investigator-Assessed Progression-Free Survival (PFS)
From randomization to the first occurrence of disease progression or death from any cause, whichever occurs first (up to approximately 6 years)
Arm A vs Arm C: Overall Survival (OS)
From randomization to death from any cause (up to approximately 6 years)
Arm B vs Arm C: OS
From randomization to death from any cause (up to approximately 6 years)
PFS-12
Assessed at 12 weeks

Progression-free survival rate as measured by the proportion of patients free of progression after 12-weeks of treatment

Incidence of adverse events
Assessed until 90 days after the last dose of study treatment or until initiation of new anti-cancer therapy, whichever occurs first

Number of patients with adverse events as measured according to CTCAE v5.0

Number of Participants With Adverse Events (AEs)
Up to approximately 30.5 months

An AE was defined as any untoward medical occurrence in a participant or clinical study participant temporally associated with the use of a study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of the study intervention.

Objective Response Rate (ORR)
Up to end of treatment (average 9 months)

As defined by investigator-assessed ORR according to RECIST v1.1

Progression-free Survival (PFS) as Determined by the Investigator
From randomization to first occurrence of PD or death from any cause (up to approximately 40 months)

PFS was defined as the time from randomization to the first occurrence of PD, as determined by the investigator according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1) criteria, or death from any cause, whichever occurred first. PD was defined as at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest SOD at prior timepoints (including baseline), in addition to the relative increase of 20%, the SOD must also demonstrate an absolute increase of ≥5 mm or unequivocal progression of existing non-target lesions. Kaplan-Meier (KM) methodology was used to estimate the median PFS.

Overall Survival (OS)
From randomization to death from any cause (up to approximately 40 months)

OS was defined as the time from randomization to death from any cause. KM methodology was used to estimate the median OS.

Pre-crossover Period: Independent Review Committee (IRC)-Assessed Objective Response Rate (ORR)
From randomization up to approximately 17 months

ORR was defined as the percentage of participants with a complete response (CR) or a partial response (PR) on two consecutive occasions ≥4 weeks apart, as determined by the IRC according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1). CR=Disappearance of all target \& non-target lesions or any pathological lymph nodes (whether target or non-target) have reduction in short axis to \<10 millimeters (mm). PR=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. The study enrolled participants with measurable disease as determined by the investigator. Participants found to have non-measurable disease at baseline according to RECIST v1.1 (through IRC assessment or Protocol Deviations) were only considered responders if they achieved a CR. Percentages have been rounded off.

Percentage of Participants With Adverse Events (Cohort B)
Up to approximately 21 months
Confirmed Objective Response Rate ORR (Cohort A)
Up to approximately 21 months

Secondary Endpoints

OS in the FAS

Frequently asked questions about Tiragolumab

What is tiragolumab?

Tiragolumab is an investigational monoclonal antibody being developed by Roche Holding AG (ticker RHHBY) for the treatment of several cancer types. It is designed to bind the TIGIT immune checkpoint and is being studied in solid tumors including non-small cell lung cancer, cervical cancer, esophageal squamous cell carcinoma, and metastatic breast cancer.

What does tiragolumab target?

Tiragolumab targets TIGIT, an immune checkpoint receptor. It is classified as a TIGIT inhibitor. By binding TIGIT, the antibody is intended to interfere with an inhibitory signaling pathway in immune cells, which is the mechanism under investigation across the oncology indications where the drug is being studied.

Who makes tiragolumab?

Tiragolumab is developed by Roche Holding AG, which trades under the ticker RHHBY. Roche is running the clinical program for the antibody, including studies that combine it with atezolizumab, and the intravenous fixed-dose combination of tiragolumab and atezolizumab is part of that development effort.

What phase is tiragolumab in?

Tiragolumab is in Phase 2 development and is investigational. It has not been established as an approved therapy. The program includes Phase 2 studies in metastatic breast cancer and PD-L1-selected solid tumors, along with a Phase 3 study in extensive-stage small cell lung cancer.

What clinical trials is tiragolumab in?

Tiragolumab is being studied in several trials. NCT06342037 is a recruiting Phase 2 trial in metastatic breast cancer in the Netherlands. NCT05661578 is a completed Phase 2 study of the intravenous fixed-dose combination with atezolizumab in PD-L1-selected solid tumors. NCT04958811 is an active Phase 2 trial in non-squamous NSCLC, and NCT04665856 is a completed Phase 3 study in small cell lung cancer.
