Additional Relevant Details The EU approval of Afinitor was based on efficacy and safety data from a pivotal Phase III study (RADIANT-4) evaluating Afinitor versus placebo in patients with advanced, progressive, well-differentiated nonfunctional NET of GI or lung origin. Results showed that Afinitor reduced the risk of disease progression by 52% (hazard ratio = 0.48; 95% confidence interval [CI], 0.35-0.67; p<0.00001) compared to placebo. The data also showed Afinitor increased median progression-free survival (PFS) by 7.1 months: median PFS by central review was 11.0 months (95% CI, 9.2-13.3) in the Afinitor arm and 3.9 months (95% CI, 3.6-7.4) in the placebo arm[3].In the pivotal trial, the most common treatment-related, all-grade adverse events (AEs) (incidence >=20%) for Afinitor and placebo, respectively, were stomatitis (63% vs 19%), diarrhea (31% vs 16%), fatigue (31% vs 24%), infections (29% vs 4%), rash (27% vs 8%) and peripheral edema (26% vs 4%). The most common treatment-related grade 3/4 AEs (incidence >=5%) for Afinitor versus placebo were stomatitis (9.0% vs 0.0%), diarrhea (7.0% vs 2.0%) and infections (7.0% vs 0.0%)[3].
