Infinzi for chalgiocarcinoma -pro
AstraZeneca’s Imfinzi (durvalumab) has been approved in the US for the treatment of adult patients with locally advanced or metastatic biliary tract cancer (BTC) in combination with chemotherapy (gemcitabine plus cisplatin).
The approval by the Food and Drug Administration (FDA) was based on the results from the TOPAZ-1 Phase III trial. In an interim analysis of TOPAZ-1, Imfinzi plus chemotherapy reduced the risk of death by 20% versus chemotherapy alone (hazard ratio [HR] 0.80; 95% confidence interval [CI] 0.66-0.97; p=0.021). An estimated one in four (25%) patients treated with Imfinzi plus chemotherapy were still alive at two years compared to one in 10 (10%) treated with chemotherapy alone. Results were consistent across all prespecified subgroups, regardless of PD-L1 expression or tumour location.
