PFS was defined as time from randomization to the first occurrence of disease progression (PD), as assessed by the investigator using Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1), or death from any cause, whichever occurs first. PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum of diameters at prior timepoints (including baseline), in addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeters (mm).
OS was defined as the time from the date of randomization to the date of death from any cause.
Progression-free survival rate as measured by the proportion of patients free of progression after 12-weeks of treatment
Number of patients with adverse events as measured according to CTCAE v5.0
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.
OS was defined as the time from randomization to death from any cause. KM methodology was used to estimate the median OS.
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.

Tiragolumab is an investigational antibody being studied in oncology for several cancers, including esophageal squamous cell carcinoma, small cell lung carcinoma, metastatic breast cancer, triple-negative breast cancer, PD-L1-selected solid tumors, and non-small cell lung cancer (NSCLC). It is in Phase 2 clinical development for these indications.
Tiragolumab is a monoclonal antibody (a -mab class drug) that targets a pathway involved in cancer immunity. It is being studied in combination with other therapies, such as atezolizumab, in clinical trials for various solid tumors.
Tiragolumab is being developed by Roche Holding AG, which trades under the ticker RHHBY. The company is conducting clinical trials to evaluate the drug's safety and efficacy in multiple cancer types.
Tiragolumab is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. Clinical trials are ongoing or completed to assess its use in various oncology indications.
Tiragolumab has been studied in several trials, including NCT04300647, a Phase 2 study in cervical cancer; NCT04665856, a Phase 3 study in small cell lung cancer; NCT05661578, a Phase 2 study in solid tumors; and NCT06342037, a Phase 2 study in triple-negative breast cancer.
No, Tiragolumab is not the same as atezolizumab. Tiragolumab is a separate investigational antibody that is often studied in combination with atezolizumab, as seen in trials like NCT04300647 and NCT04665856, where the two drugs are given together.
