RecruitingPhase 3Drug trialEfficacy and Safety of Radiotherapy Compared to Everolimus in Somatostatin Receptor Positive Neuroendocrine Tumors of the Lung and Thymus.LEVEL trial aims to demonstrate the higher efficacy of 177Lu-edotreotide over everolimus in patients with well to moderately differentiated neuroendocrine tumors of the lung and thymus who require systemic therapy. It is hypothesized that 177Lu-edotreotide may significantly increase the progression-free survival (PFS) compared to everolimus in lung and thymic carcinoids.
