Basel, 5 January 2021 – Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that tiragolumab, a novel cancer immunotherapy designed to bind to TIGIT, has been granted Breakthrough Therapy Designation (BTD) by the US Food and Drug Administration (FDA), in combination with Tecentriq® (atezolizumab) for the first-line treatment of people with metastatic non-small cell lung cancer (NSCLC) whose tumours have high PD-L1 expression with no EGFR or ALK genomic tumour aberrations. Tiragolumab is the first anti-TIGIT molecule to be granted BTD from the FDA, and the designation is based on randomised data from the phase II CITYSCAPE trial. CITYSCAPE provides the first evidence that targeting both immune inhibitory receptors, TIGIT and PD-L1, may enhance anti-tumour activity by potentially amplifying the immune response.1
