Lung Neuroendocrine Neoplasm

This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in the body (advanced). Lutetium Lu 177-dotate is a radioactive drug. It binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Lutetium Lu 177-dotatate builds up in these cells and gives off radiation that may kill them. It is a type of radioconjugate and a type of somatostatin analog. Lutetium Lu 177 dotatate may be more effective than everolimus in shrinking or stabilizing advanced bronchial neuroendocrine tumors.

This phase IIa trial compares the safety and effect of temozolomide combined with survivin long peptide vaccine (SurVaxM) to temozolomide alone in patients with neuroendocrine tumors (NET) that has spread from where it first started (primary site) to other places in the body (metastatic) and is growing, spreading or getting worse (progressing). Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid and may kill tumor cells and slow down or stop tumor growth. Survivin, a protein, is expressed in 50% of patients that have neuroendocrine tumors and, is associated with poor outcomes. SVN53-67/M57-KLH peptide vaccine (SurVaxM) is a vaccine that has been shown to produce an immune system response against cancer cells that express a survivin and may block the growth of new tumor cells. Giving temozolomide with SurVaxM may kill more tumor cells in patients with progressing metastatic neuroendocrine tumors.

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.

The aim of CABOTEM study is to demonstrate the safety and activity of the Cabozantinib and Temozolomide combination in Lung and GEP-NENs patients, progressing after a first line therapy, including target therapies (everolimus, sunitinib) and / or chemotherapy, in the approved setting.
