Tiragolumab (development names RG6058 and MTIG7192A) is a humanized monoclonal antibody that functions as an immune checkpoint inhibitor by targeting the T-cell immunoreceptor with Ig and ITIM domains (TIGIT) pathway.[1][2] Developed by Genentech and Roche, the drug is designed to enhance anti-tumor immune responses when used in combination with other immunotherapy agents, particularly atezolizumab (Tecentriq).[1]

In January 2021, tiragolumab received breakthrough therapy designation from the U.S. Food and Drug Administration (FDA) for use in combination with atezolizumab in the treatment of patients with PD-L1-high metastatic non-small-cell lung cancer (NSCLC) who do not harbor EGFR mutations or ALK rearrangements.[3]
