Everolimus in advanced, progressive, well-differentiated, nonfunctional neuroendocrine tumors: RADIANT-4 lung subgroup analysis

Summary

In the phase 3, RADIANT-4 study, everolimus improved median progression-free survival (PFS) by 7.1 months in patients with advanced, progressive, well-differentiated (grade 1 or grade 2), nonfunctional lung or gastrointestinal neuroendocrine tumors (NETs) vs placebo (hazard ratio [HR], 0.48; 95% confidence interval [CI], 0.35-0.67; P < .00001). This exploratory analysis reports the outcomes of the subgroup of patients with lung NETs. In RADIANT-4, patients were randomized (2:1) to everolimus 10 mg/d or placebo, both with best supportive care. This is a post hoc analysis of the lung subgroup with PFS, by central radiology review, as the primary endpoint; secondary endpoints included objective response rate and safety measures. Ninety of the 302 patients enrolled in the study had primary lung NET (everolimus, = 63 and placebo, = 27). Median PFS (95% CI) by central review was 9.2 (6.8-10.9) months in everolimus arm vs 3.6 (1.9-5.1) months in placebo arm (HR, 0.50; 95% CI, 0.28-0.88). More patients who received everolimus (58%) experienced any tumor shrinkage compared with placebo (13%). Most frequently reported (≥ 5% incidence) grade 3-4 drug-related adverse events (everolimus vs placebo) included stomatitis (11% vs 0%), hyperglycemia (10% vs 0%), and any infections (8% vs 0%). In patients with advanced, progressive, well-differentiated, nonfunctional lung NET, treatment with everolimus was associated with a median PFS improvement of 5.6 months, with a safety profile similar to that of the overall RADIANT-4 population. These results support the use of everolimus in patients with advanced, nonfunctional lung NET.
