The safety and efficacy of Tecentriq were studied in a single-arm phase II clinical trial involving 310 patients, and measured objective response rate. The study also looked at the difference in effect based on positive versus negative expression of the PD-L1 protein on patients’ tumor-infiltrating immune cells.
In all patients, 14.8 percent of participants experienced at least a partial shrinkage of their tumors, an effect that lasted from 2.1 to over 13.8 months at the time of the response analysis. In patients who were classified as positive for PD-L1 expression, 26 percent of participants experienced a tumor response, compared to 9.5 percent of participants who were classified as negative.
The FDA previously granted Tecentriq breakthrough therapy designation and priority review status.
