Abstract

Background:

Large-cell neuroendocrine carcinoma of the lung (LCNEC) is a rare disease with poor prognosis and limited treatment options. Neuroendocrine tumors frequently show overactivation of the mTOR pathway. Based on the good activity of the mTOR inhibitor everolimus in different types of neuroendocrine tumors and the results of a previous phase I trial, we evaluated the efficacy and safety of everolimus in combination with carboplatin and paclitaxel as upfront treatment for patients with advanced LCNEC.

Patients and methods:

In this prospective, multicenter phase II trial chemotherapy-naive patients with stage IV LCNEC received 5 mg everolimus daily combined with paclitaxel 175 mg/m2 and carboplatin AUC 5 every 3 weeks for a maximum of four cycles followed by maintenance everolimus 5 mg daily until progression. Efficacy parameters were determined based on central radiologic assessment.

Results:

Forty-nine patients with a mean age of 62 ±9 years and a predominance of male (71%) smokers (98%) were enrolled in 10 German centers. The overall response rate was 45% (95% confidence interval [CI] 31%-60%), the disease control rate 74% (CI 59%-85%), the median progression-free survival 4.4 (CI 3.2-6) months and the median overall survival 9.9 (CI 6.9-11.7) months. The progression-free survival rate at 3 months (primary end point) was 76% (CI 64%-88%) according to Kaplan-Meier. Grade-3/4 toxicities occurred in 51% of patients and mainly consisted of general physical health deterioration (8%), cytopenias (24%), infections (10%) and gastrointestinal problems (8%). Typical everolimus-related adverse events, like stomatitis, rash and ocular problems occurred only in a minority of patients (<15%) and were exclusively of grade 1-2.

Conclusion:

Everolimus in combination with carboplatin and paclitaxel is an effective and well-tolerated first-line treatment for patients with metastatic LCNEC.
