A prospective observational study on the evaluation of everolimus-related adverse events in metastatic renal cell carcinoma after first-line anti-vascular endothelial growth factor therapy: the AFINITE study in France

Abstract

Purpose

The objective of the study was to describe the occurrence of stomatitis and noninfectious lung disease in patients with metastatic renal cell carcinoma (mRCC) treated with second-line everolimus in a real-world setting.

Methods

This multicenter, prospective, observational study was conducted in France by physicians with experience of treatment of patients with mRCC. Patients aged ≥18 years who received everolimus after first-line antivascular endothelial growth factor (VEGF) therapy were included in the study. The primary safety assessments were occurrence of stomatitis (in terms of severity, event dates, and therapeutic management) and noninfectious pneumonitis (in terms of detection methodology, severity, event dates, and therapeutic management).

Results

Between September 2010 and August 2012, 284 patients were enrolled at 77 centers, of whom, 274 received everolimus therapy. Most patients had mRCC of clear cell histology (88%), and most of them (84%) received first-line sunitinib. In total, 40% of patients experienced treatment-related stomatitis, and 15% of patients experienced noninfectious lung disease. Most of them had a single episode. The incidence of grade 3 stomatitis and noninfectious lung disease were 8 and 3%, respectively. Mean time to the first episode was 27 days for stomatitis and 72 days for noninfectious lung disease from treatment initiation. Stomatitis and noninfectious lung disease resulted in treatment discontinuations in 2 and 7% of patients, respectively. The primary first-episode treatment was mouthwash (86%) for stomatitis and corticosteroids (65%) for noninfectious lung disease.

Conclusions

This study confirms that stomatitis and noninfectious lung disease are commonly associated with everolimus use. Both adverse events were rarely severe and were managed easily and efficiently.
