Expression of somatostatin receptor 2 (SSTR2) is frequently seen in functional imaging in lung-NETs opening the opportunity to treat SSTR2 positive patients with radioligand therapies (RLT). Retrospective data suggest a potential meaningful benefit of RLT directed to SSTR2 in lung-NET patients. Methods The LEVEL trial is a randomized, open-label, phase III international trial of 177Lu-edotreotide versus everolimus in patients with progressive, locally advanced or metastatic, and well/moderately differentiated NETs of lung (typical/atypical) or thymic origin. Patients could be treatment-naïve or have progressed (PD) on somatostatin analogues or ≤ 2 additional systemic treatments. Prior RLT or mTOR inhibitors are not permitted. Eligible patients are randomly assigned 3:2 to 6 cycles of 177Lu-edotreotide (total administered activity 7.5 ± 0.7 GBq / cycle) or to oral everolimus 10 mg once daily until PD or unacceptable toxicity. Only patients with positivity in somatostatin receptor imaging will be included. CT or MRI scans are performed every 12 weeks until PD. Blood samples are analyzed at baseline, at 1st tumor assessment, and at PD for pharmacodynamic endpoints. Archival tumor tissue samples will be analyzed for ancillary studies. The primary endpoint is progression-free survival (PFS) according to RECIST v1.1 based on local investigator assessment. Secondary endpoints include overall survival, overall response rate, safety, and quality of life (EORTC QLQ-C30). The expected sample size is 120 patients to demonstrate statistical significant risk reduction of 46.4% (HR = 0.536) in PFS with the experimental treatment using an overall 5% two-sided alpha error with 80% power. An interim PFS analysis was included using the Lan-DeMets with O’Brian-Fleming-like boundaries. Discussion The LEVEL trial will investigate if 177Lu-edotreotide has the potential to be incorporated as a standard treatment option for patients with NETs from the lung and Thymus.
