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.

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.

Treatment patterns, risk factors and outcomes for patients with newly diagnosed hepatocellular carcinoma in France: A retrospective database analysis.

BACKGROUND & AIMS: The aim of this analysis was to describe the nationwide distribution of patients with newly diagnosed hepatocellular carcinoma (HCC) according to treatment patterns, aetiologies, and outcomes in France. METHOD: A retrospective cohort of patients with newly diagnosed HCC was selected over the period 2015-2017 in a French claims database covering 99% of the population. Treatment patterns were described using an algorithm based on a ranking of curative and palliative HCC treatments identified. Survival was analyzed using Kaplan-Meier curves according to major treatments and aetiologies. RESULTS: A total of 20,083 incident patients were identified with a mean age of 69.2 years (SD: 11.0) and 82.4% of men. The mean duration of follow-up was 10.0 months (SD: 9.7). At least one HCC risk factor could be identified in 87.0% of patients. The most frequent aetiologies were alcohol-related liver disease present in 50.8% of patients, a metabolic disease (NAFLD, NASH or diabetes) without alcohol or viral hepatitis (44.5%) and viral hepatitis (20.0%). Only 32.7% of patients received a curative therapy, with a 1-year survival of 89.5%, while 38.0% of patients received only best supportive care, with a 1-year survival of 12.9%. The highest rates of curative treatments were found in patients with viral hepatitis, associated or not with another risk factor. CONCLUSION: Hepatocellular carcinoma was still most often diagnosed at an advanced disease stage as shown by the low rate of curative treatment observed and the very poor prognosis. Viral aetiology was associated with the best survival.

Clinical Benefit of Everolimus as Second-Line Therapy in Metastatic Renal Cell Carcinoma: The French Retrospective SECTOR Study.

BACKGROUND: Real-world data of everolimus after vascular endothelial growth factor receptor (VEGFR)-tyrosine kinase inhibitor (TKI) therapy in metastatic renal cell carcinoma (mRCC) are limited. PATIENTS AND METHODS: The retrospective, noninterventional SECTOR (SECond line with afiniTOR) study (N = 165) assessed outcomes of second-line everolimus after initial VEGFR-TKI (TKI-everolimus, n = 144) and of third-line VEGFR-TKI after everolimus (TKI-everolimus-TKI, n = 59) in patients with mRCC. The primary end point was duration of everolimus therapy for both populations. RESULTS: Median duration was 4.0 months (range, 0.0-33.0 months) for second-line everolimus and 18.0 months (range, 2-78 months) for sequential VEGFR-TKI and everolimus. Median overall survival (OS) for this sequence was 36.0 months (95% confidence interval [CI], 27.0-56.0 months) and was longer for patients who received a first-line TKI for ≥ 9 months (not reached) than for < 9 months (28.0 months; P < .001). During second-line everolimus treatment, commonly reported adverse events (all grades) were fatigue (n = 66, 40.7%), anemia (n = 58, 35.8%), and stomatitis (n = 41, 25.3%). Median duration from initiation of first-line TKI to the end of the third-line TKI was 24.0 months (95% CI, 19.0-29.0 months). Median OS for this sequence was 41.0 months (95% CI, 25.0-57.0 months) and was significantly longer for patients who received the first-line TKI for ≥ 9 months (37.5 months) than for < 9 months (19.0 months; P < .0001). CONCLUSION: These results reflect clinical use of sequential TKI-everolimus and TKI-everolimus-TKI and provide additional evidence that everolimus could be an option in second-line therapy in mRCC. Results of the CheckMate-025 (Nivolumab versus Everolimus in Advanced Renal-Cell Carcinoma) and METEOR (Metastatic RCC Phase 3 Study Evaluating Cabozantinib versus Everolimus) studies might change the treatment landscape.

Everolimus for patients with metastatic renal cell carcinoma refractory to anti-VEGF therapy: results of a pooled analysis of non-interventional studies.

AIM: To assess the efficacy and safety of everolimus in patients with metastatic renal cell carcinoma (mRCC) who failed one or two anti-VEGF therapies. PATIENTS AND METHODS: Data from four prospective, non-interventional studies conducted in Germany, France, Greece and Austria were pooled for this analysis. Patients with mRCC of any histology (clear cell or non-clear cell) were included. VEGF-refractory patients received everolimus 10mg/day until disease progression or unacceptable toxicity. The primary objective was to determine everolimus efficacy as measured by time to progression (TTP; from baseline to progression). RESULTS: The overall population comprised 632 patients; 493 patients received everolimus in the second-line setting. Most patients were of favourable/intermediate MSKCC risk (91%), had clear cell mRCC (89%), and had undergone nephrectomy (89%). Median TTP was 6.3months (95% confidence interval [CI], 5.9-6.8) for the overall population and 6.4months (95% CI, 5.8-6.9) for the second-line everolimus population. Similarly, median progression-free survival was 5.5months (95% CI, 5.0-6.1) for the overall population and 5.8months (95% CI, 5.0-6.4) for second-line everolimus population. Best tumour response (n=349) was complete or partial remission in 12% of patients and stable disease in 59% of patients. Overall population median overall survival (OS) was 11.2months (95% CI, 9.0-not reached). Commonly reported adverse events (AEs) (any grade) were stomatitis (25%), anaemia (15%) and asthenia (11%). CONCLUSIONS: Results of this pooled analysis provide evidence of safety and effectiveness of second-line everolimus in routine clinical use and support everolimus as a standard of care for VEGF-refractory patients with mRCC.

Efficacy and Safety of Sequential Use of Everolimus in Patients With Metastatic Renal Cell Carcinoma Previously Treated With Bevacizumab With or Without Interferon Therapy: Results From the European AVATOR Study.

BACKGROUND: Everolimus is a mammalian target of rapamycin (mTOR) inhibitor. It gained approval based on the results of the RECORD-1 (Regulation of Coagulation in Orthopedic Surgery to Prevent Deep Venous Thrombosis and Pulmonary Embolism 1) trial, which included patients with metastatic renal cell carcinoma (mRCC) whose disease progressed after receiving vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs). Bevacizumab is a monoclonal antibody targeting angiogenesis that is approved in patients with mRCC. The sequence of everolimus second-line therapy after failure of bevacizumab ± interferon (IFN) first-line therapy has not yet been studied. METHODS: AVAstin(®) followed by afiniTOR(®) (AVATOR) was a noninterventional retrospective multicenter European observational study of 42 unselected patients with mRCC who were previously or currently treated with everolimus after failure of bevacizumab ± IFN. The primary end point was everolimus progression-free survival (PFS). Secondary end points were related to the overall survival (OS) of patients receiving the drug sequence and everolimus treatment and safety. RESULTS: Exploring the duration of second-line everolimus treatment, 63.8% of patients received at least 3 months of everolimus and 28.8% received at least 8 months of treatment. At the time of data analysis, 15 patients (36%) were still receiving everolimus, 40% had stopped because of progressive disease, and 24% had discontinued treatment for other reasons. Patients receiving everolimus after bevacizumab experienced a median PFS of 17 months (95% confidence interval [CI], 5 [not reached]). Median OS was not reached with everolimus second-line therapy. At 32 months after the start of first-line therapy, 53.3% of patients were still alive. All grades of common adverse events (AEs) were consistent with the known safety profile of everolimus. CONCLUSION: The AVATOR-studied sequence displayed a longer than expected median PFS. Further prospective exploratory studies need to be performed to confirm these encouraging results in a larger cohort of patients.
